The invention relates to an electrification preventing
implement and an method electrification preventing according to claims 1 and 2,
wherein minus ions are used for improving environment by removing static electricity.
It is generally known that stray current flows in the atmosphere
and the earth. The intensity varies depending on changes in atmospheric potential
caused by changes in weather, geographic features, and other natural conditions,
and also depending on artificial things such as electric apparatuses, railways,
power cables, and so forth and is influenced with metalliferous veins, ground water
arteries, and underground cables, if they are present. Ordinarily, in the ground
with a height above the sea of 100 m, earth current with an intensity of about 15
µA flows. However, in the modern society, with the spread of electric
apparatus, the intensity of the stray current has been higher almost in any place.
This appears as static electricity which is electrified on the earth. In event that
earth current having an intensity of 30 to 40 µ A flows through a human
body to electrify, there is a great possibility that the current causes various
hindrances to men's health. Light symptoms caused by the electrification include
stiffness in the shoulder, headache, fatigue feeling, and so forth. However, if
the electrification lasts in a long term, or the charge quantity is high, the morbid
symptoms become severe. In some cases, their human relations are badly influenced
with the poor physical conditions.
The electrification exerts a bad influence not only over
human bodies but also over plants, animals, and even objects. The bad influences
can be appreciated as follows; for plants, the growing rate is decreased, the vitality
of forests is deteriorated, and for animals, the vitality is reduced, and the morbid
symptoms appear. In an electrified condition, cat fish can hardly foreknown an earthquake,
cat fish in the river being well-known as an animal having ability to foreknow an
earthquake in Japan.
Though the electrostatic charge, generated by the electrification
of an object, is effectively used in some cases, they may cause the following hindrances:
mechanical hindrances occur, that is, electrified objects such as powder, fibers,
sheets, and so forth get to be caught in other objects, combustible and explosive
objects are ignited when static electricity is discharged, which may induce fires
and explosions, and the electrostatic charge may be a cause of the breaking, error
action, quality-deterioration of precision apparatuses such as semiconductor parts,
and so forth.
Conventionally, as a method of inhibiting the residence
of earth current to prevent the electrification in a wide area the embedment of
carbon is carried out. Hereinafter, the embedment of carbon will be described.
For example, as shown in FIG. 1, for a building lot wi
th a land area of 100 tsubo (1 tsubo = 3.3m2) and a building area of
40 tsubo, embedment pits 11 with a diameter (r) of 1 m and a depth (d) of 1 to 2
m are dug at intervals (p) of 5 to 10 m. 200 to 500 kg per pit of carbon 12 (for
example, coconut shell carbon) is embedded into a pit. The carbon 12 may have a
form of grains or powder, depending on the conditions of the land 13 and the building
14. The intervals between the embedment pits 11 can be changed depending on the
conditions of the land and the building. FIGS. 2A and 2B are sectional model views
of the embedment pits 11. FIG. 2A shows pits provided in a level ground. The pits
shown in FIG. 2B are provided in a sloping land (the building lot is an embankment).
In the case of such sloping lands as shown in FIG. 2B, the carbon 12 is embedded
in the mountain-shape land at the same horizontal-level.
When the carbon is embedded, the electric resistance is
reduced as a whole, so that the stray current flows, swirling and spreading as shown
in FIG. 3 (side view) and FIG. 4 (plan view). This reduces the electrification of
men, plants and animals, and objects present in the land in which the carbon is
embedded, that is, reduces the static electricity on the ground. Such phenomena
are effective to a height above the sea level of about 3 m, which serves for the
stabilization of them.
FIG. 5 is a plan view which illustrates the application
to a factory and a farm. The embedment pits 11 for embedding the carbon 12 have
an interval (p) of 10 m, are provided in the sites positioning at the apexes of
a triangle. The embedment quantities of the carbon 12 are controlled according to
the potential inclination. In the case of the potential inclination to be provided
in the lateral direction as shown in FIG. 5, 200 kg of the carbon 12 is embedded
in the embedment pit 11 in the highest potential site, and 500 kg of the carbon
12 is done in the embedment pit 11 in the lowest potential site. Between both sites,
the quantities of the carbon to be embedded are determined according to the proportional
distribution. Also, in the case of the potential inclination in the longitudinal
direction of the drawing, the quantities of the carbon to be embedded are controlled.
The embedment pits 11 have a diameter of 1 to 1.2 mm and a depth of 1 to 2 m. In
this case, it is desirable that the carbon 12 is embedded in the mountain-shape
land at the same horizontal level. The case where the carbon embedment is applied
to the factory and farm can also obtain a similar effect to the case of residential
When the embedment of the carbon is carried out, 1 to 2
tons of the carbon 12 is required for a house. For the application to a factory
(lot 1000 tsubo, building 500 tsubo), 10 to 30 tons of the carbon 12 is needed.
In addition, many embedment pits 11 are dug. The overall amount of money including
the construction cost is vast. The economical burden is very heavy.
When carbon is sprayed on the ground surface to a thickness
of about 3 to 10 cm, effects to some degree can be obtained. However, the effects
are lower as compared with the underground embedment, and the effectiveness-lasting
time is short, that is, about half a year.
The influence of static electricity is more apparently
recognized indoor, as compared with the outdoor condition. For the purpose of making
indoor air more comfortable or activating the indoor air, air cleaning devices having
function for generating minus ions, infrared ray generators, static-electricity
removing devices, dehumidifiers, humidifiers, and so forth have been rapidly spread.
In addition, bedding (futon, pillows), clothes, cosmetics, and so forth which allow
minus ions to act on human bodies have been practically used.
The effects of minus ions can be explained based on the
biological action of atmospheric ions or the principle of the ion introduction.
The causes of the atmospheric ions include ionization effects
by space rays, ultraviolet rays, natural radioactive substances, atmospheric discharge
(lightning), and so forth, and triboelectricity generated at snow falling, effects
accompanied by the changes in surface area of water drops, the Lennard effect, and
so forth. Also, the phenomenon is called global circuit wherein minus ions flow
between ionosphere and earth circularly, and current flows in the opposite direction.
It is generally thought that as the biological actions of the atmospheric ions generated
by the above-mentioned causes, the minus ion alkaline atmosphere has systematic
actions such as tranquil, invigorating, hypnotic, appetite promoting actions, and
so forth, blood pressure drop action, blood sugar reduction, vasodilatation, diuretic
action, and so forth. On the other hand, it is generally thought that the plus ion
acidic atmosphere has systematic actions such as excitable, unpleasant feeling sleeplessness,
appetite diminishment, and so forth, blood pressure rising action, blood sugar increasing
action, vasoconstriction, diuretic inhibition action, and so forth.
The principle of the ion introduction is that various substances
are ionized by the application of electrolytic action, and through the ions an objective
substance itself is permeated into subcutaneous tissues. It is generally thought
that when the activated oxygen is absorbed into a layer near the skin surface, the
acidic horny layer is neutralized to be softened and the metabolism of the skin
becomes active, recovering the skin function to its normal state.
In addition, the minus ions enhance the blood flow in the
skin, adjusts the function of the autonomic nervous system, makes the blood alkaline
so as to activate the functions of the cells. Thus, the minus ions has a positive
action to prevent the skin aging and dissolve other troubles. Moreover, the minus
ions, normalizing the skin functions, are very effective in prevention of the loss
of hair and hair restoration.
In the indoor condition, minus ions, when they are generated
with a device having a minus ion generating function, neutralizes the plus charge
and further can convert to the minus ion environment. However, when the removal
of electrostatic charge or the activation of a space is attempted with an electric
apparatus, there exists such a problem that the electrostatic charge quantity is
increased, due to the fact that the electric apparatus itself is charged, even though
the air is cleaned.
Moreover, it is desired to clean water and air which are
indispensable to the preservation of our life.
Conventionally, drink water is obtained by treating river
water and groundwater (raw water) to clean, if necessary. As means for treating
water to clean, (1) the flocculation of suspended matters, and the solid - liquid
separation, (2) the coagulation of dissolved matters, oxidation, biochemical modification,
adsorption, and ion exchange, (3) the agglutination and filtration of bacteria and
virus, and their disinfection, (4) the neutralization of acids and alkali, and so
forth are exemplified, and are employed in combination of them depending on the
In general, underground water, not containing objects to
be removed, has good water qualities. Therefore, the underground water, after it
is subjected to chlorine disinfection only, is supplied. On the other hand, for
river water and lake water, viscosity colloids, algae plankton, and contaminants
deriving from the nature are objects of the water cleaning. For this purpose, the
slow sand filtration or quick sand filtration system is employed.
According to the slow sand filtration system, in addition
to the mechanical filtration of suspended matters, the oxidation, adsorption and
decomposition of ammonia, iron, manganese, organic components, and smell components
with microorganisms propagating in the surface layer, the predation with water bacteria,
and the stabilization of nitrogen components with bacteria in the sand layer can
According to the quick sand filtration system, viscosity
colloids and color colloids in water are flocculated by the addition of a coagulant
having a positive charge, and then the flocculation is precipitated and filtrated
to be separated. As the coagulant, aluminium salts are mainly used. In part, iron
salts and high polymeric substances are used. Even by the quick sand filtration
system, dissolved contaminants can be flocculated, precipitated and filtrated to
be cleaned to some degree, using an oxidizing agent, the absorption into aluminium
hydroxide, and the coagulation. For extreme contamination and bad smells, the oxidization
with ozone and the adsorption to active carbon are further used in some cases.
Water with physiological safety for drinking or tasteful
water contains minerals dissolved out of rocks and stones in an appropriate amount.
In the case of ultra-pure water required, processes such as ultra fine filtration,
multi-step reduced-pressure distillation, ion exchange, reverse osmosis, and so
forth are used to produce pure water on a required water-quality level. As described
above, many water cleaning methods suitable for the respective uses of water have
In recent years, with the more contamination of raw water,
the amounts of chlorine and chlorinated lime used in the above-described processes
have been increased. However, there have been more people who are sensitive to the
taste and smell of the chlorine and the chlorinated lime and dislike them. For this
reason, water cleaning devices for cleaning tap water in their homes have been widely
spread. There are various types of such water cleaning devices. That is, ones are
attached to taps, and others are placed in the cabinets of sinks, and so forth.
However, the water cleaning devices to be attached to taps have such problems that
the taps become heavy to be handled, persons using tap water can not sufficiently
see the working space under the water cleaning devices. For the water cleaning devices
to be placed in the cabinets of sinks, there are such problems that the spaces for
working in the cabinets are reduced. For both types of the water cleaning devices,
it is necessary to maintain them, e. g., exchange the fillers.
For preventing of indoor bad smells, deodorants using active
carbon and so forth, deodorizing sprays, perfumes for emitting various scents, and
so forth are available. With conventionally used deodorants and deodorizing sprays,
it is difficult to deodorize smells sufficiently. As to perfumes, perfumes are liked
or disliked by different persons. In some cases, persons feel that perfumes smell
In addition, air conditioners having an air cleaning function
have been spread. However, their spread is inhibited because the devices are too
expensive, the large-scale attachment is necessary, and for use of the devices,
electricity is required.

container in which a mineral is received. The mineral may comprise rose quartz in
granular form and the container is made of plastics or an epoxy resin.

The present invention has been devised to solve abovementioned
problems. A main object of the invention is to provide an electrification preventing
implement and an electrification preventing method with use of minus ions.
This object is solved by providing an electrification preventing
device and a method of preventing electrification according to claims 1 and 2 which
are applicable to reduce electrification of static electricity due to stray current
easily, using relative inexpensive means, and prevent a human body, a plant, an
animal, and an object from being electrified.
An electrification preventing device of the invention is
characterized in that a predetermined granular and/or powdery element and/or compound
is sealed in a glass tube. Said element and/or compound may be Si and/or SiOx
A method of preventing electrification of the invention
is characterized in that the electrification preventing device is embedded underground
in the vertical direction.
It is preferred to use an element or compound minus ionized
previously. Higher effects can be obtained as the ionization degree is higher.
The above and further objects and features of the invention
will more fully be apparent from the following detailed description with accompanying

Hereinafter, the present invention will be described in
detail, in reference to the drawings showing embodiments.
FIG. 6 is a schematic view showing an electrification preventing
implement of the present invention. In a Pyrex tube (reinforced glass tube) 1, 500
to 600 g of granule or powder of, for example, silicon (Si) 2 is tightly sealed.
The silicon 2 is previously placed in a minus-ionized quartz crucible for a predetermined
time to be minus-ionized.
An appropriate hole is dug nearly in the center of a house,
a factory, or a farm. One electrification preventing implement 3 is vertically embedded
in the hole.
FIG. 7 is a side view of the house in which the electrification
preventing implement 3 is embedded and its neighborhood. FIG. 8 is a plan view of
the house and its neighborhood. When flow current is measured using a tester to
quantify static electricity in the land 100 m above the sea level, the result was
30 to 40 µA. The static electricity was reduced to about 15
µA by the embedment of the electrification preventing implement 3. Probably,
this is because the stray current on the ground surface and its neighborhood was
allowed to flow easily and the residing static electricity was discharged to be
eliminated. The embedment of the implement 3 reduces the intensity of current flowing
human body, inhibiting the above-mentioned hindrances to men's healthy and morbid
With the clockwise eddy of electric current as shown in
FIGS. 7 and 8, minus ions from the silicon 2 so act that the concentration of minus
ions in the house and its neighborhood is increased. It is generally known that
the minus ions are effective in recovery from fatigue, cleaning of blood, and so
forth. Air cleaning implements, bedding (futon, pillows), and so forth having such
functions have been widely used. With the electrification preventing implement 3
embedded, minus ions from the silicon 2 activates hydrogen molecules. Thus, a comfortable
living space in which the air is cleaned can be obtained. As to human bodies, effects
whether they are physical or mental can be appreciated. For example, a person feels
himself agile, becomes more patient, and so forth.
According to the method of this invention, a hole for embedding
only one electrification preventing implement 3 is merely dug. The method can be
carried out more easily as compared with conventional embedment of carbon. As only
one glass tube is embedded, the implement can be easily transported.
In a fish feed factory filled with bad smells, the bad
smells disappeared immediately after the electrification preventing implement 3
When the implement 3 was applied to a farm, plants were
activated, and the growth rate was enhanced.
When the three to six implements 3 are embedded in a lake,
the water is cleaned.
It is verified that the effects of the electrification
preventing implement 3, which has a length of 1 m, extends to the space about 25
m above the ground level. In the case of a length of 1.5 m, the effects extend to
the space about 50 m above the ground level. Thus, the length and the diameter of
the Pyrex tube 1, and the amount of the silicon 2 can be appropriately selected,
depending on lands and buildings, The effects are long-lasting. A plurality of implements
3 may be embedded. The larger number of the implements 3 is, the larger effect is
Though Si is used in the above embodiments, SiOx
may be used. With component of SiOx, good effects can be obtained provided
that x is a number of from 1.00 to 1.95.
Higher effects can be obtained as the ionization degree
As abovementioned, the embedment of a glass bar including
silicon therein allows stray current to flow easily under and above ground. This
can prevent electrification having a bad influence on a human body, animals, plants
