Description

Charged charge reduction device and member

The present invention relates to a charged charge reducing device and a member.

The existence of electronic equipment and electrical equipment is indispensable for conducting modern daily life.

Electronic equipment refers to electrical products that apply electronic technology, and includes equipment that digitally processes information, equipment that electrically processes video and audio, and the like. Examples of electronic devices include computers, televisions, displays, audio equipment, car navigation systems, mobile phone terminals, smartphones, personal digital assistants (PDAs), game machines, CD players, DVD players, digital cameras, electronic notebooks, electronic dictionaries, Calculator, hard disk recorder, video camera, printer, radio, etc.

“Electrical equipment” refers to equipment that uses electricity in general, and includes, for example, refrigerators, washing machines, vacuum cleaners, air conditioners, electric kettles, lighting fixtures, and microwave ovens.

By the way, the electronic parts used in electronic devices and electric devices are becoming lighter and smaller, and the influence of static electricity on the electronic parts is increasing.

For example, if you continue to use a personal computer for a long time, the electronic components may be charged with static electricity, making it difficult to turn on the computer or making the computer unstable. In some cases, a phenomenon called electrostatic breakdown in which electronic components are destroyed by static electricity may occur, and the computer may malfunction or fail to start.

Also, for example, it is known that when a speaker, which is an acoustic device, is in a charged state, the sound reproducibility is affected and the sound quality is degraded.

Therefore, methods for preventing electrification of electronic parts used in electronic devices and electric devices have been studied, and various methods have been proposed.

For example, in Patent Document 1, a housing that houses a board on which an electronic component is mounted and a first electronic component that is connected to the board and has a ground terminal, and a through-hole that opens to the outside is formed in the housing. In the portable electronic device having a housing, the first electronic component has an exposed conductive portion that is electrically connected to a ground terminal, and the conductive portion is at least partially opposed to the through hole, It has been proposed to be disposed closer to the through hole than other electronic components. According to this portable electronic device, even if the discharge from the charged body causes a discharge toward the through hole of the housing, the first electronic component having the ground terminal is disposed adjacent to the through hole. Therefore, static electricity is discharged to the ground terminal of the first electronic component and escapes to the ground. Therefore, it is possible to prevent electrostatic discharge from being discharged to other electronic components such as chips.

Further, in Patent Document 2, in an antistatic circuit provided with an antistatic capacitor provided between a signal ground and a chassis ground, there is a forward direction between the capacitor and the signal ground or the chassis ground. It has been proposed to include two rectifying elements that are connected in parallel so as to have opposite directions and have a predetermined capacitance. According to this static electricity countermeasure circuit, static electricity may be applied to the signal ground via an external terminal or the like. In that case, the high-frequency component of the applied electrostatic pulse can be released to the chassis ground via a static electricity countermeasure capacitor in the same manner as in the past without being hindered by the two rectifying elements facing in the opposite direction. On the other hand, when a ground loop is formed via an anti-static circuit, the ground loop passes through two rectifying elements having a predetermined capacity. For this reason, by reducing the capacitance of each rectifying element, the frequency of the ground loop current that can be generated is limited to an extremely high frequency that is much higher than when the ground loop passes only through an anti-static capacitor. be able to. Therefore, for example, the generation of a relatively low frequency ground loop current that affects the audio signal can be prevented, and the influence of the ground loop current can be virtually eliminated.

However, although the portable electronic device described in Patent Document 1 and the static electricity countermeasure circuit described in Patent Document 2 are both effective in reducing charged charges, the structure of the device itself has a specific structure. Yes, it is not a measure that users can attach to purchased devices later. Therefore, it is desirable to provide a method that can be retrofitted by the user without modifying a purchased device.

As a method that can be implemented later by the user, the user may handle an electronic device or an electric device after touching a metal part such as a water tap. More preferably, the user may handle the electronic device or the electric device after hand washing.

Further, in Patent Document 3, one end of the first conductor piece and the first conductor piece, which are arranged to face each other via the zinc oxide varistor element, and the first conductor piece are in electrical contact. The second conductive pair piece is connected and the other end is electrically contact-connected, and the first conductive piece and the second conductive piece are brought into contact with the first conductive piece by bringing the electrostatic charging member into contact with the first conductive piece. The static eliminator in which the charge induced electrostatically in the conductor piece is discharged and absorbed by the zinc oxide varistor element in a state where the first conductor piece and the second conductor piece are not grounded by dielectric polarization ( So-called “static bracelets”) have been proposed.

Moreover, in patent document 4, the contact part which receives the contact from a human body, one end electrically connected with the said contact part, and the other end electrically connected with the reference electric potential part, and the said contact part A static eliminating device (so-called “static eliminating sheet”) is proposed, comprising an insulated antenna portion for detecting the potential of the contact portion, and an informing means for informing the potential detected by the antenna portion. ing.

However, it is bothersome and often forgotten for the user to touch or wash the faucet etc. every time before handling the electronic device or electric device. . Therefore, it cannot be said that it is a reliable measure.

Also, as described in Patent Document 3, it is necessary for the user to always wear the so-called “static discharge bracelet”, which is troublesome for the user.

In addition, as described in Patent Document 4, when using a so-called “static removal sheet”, the user should touch the “static removal sheet” before handling the electronic device or the electric device. This is what is required and is troublesome for the user. Further, although charging to electronic devices and electrical devices derived from human contact can be prevented, charging to electronic devices and electrical devices derived from others cannot be prevented.

The present invention has been made in view of such problems, the purpose of which can be retrofitted by a user to a purchased device, and does not require the user to perform any work for each use of an electronic device, An object of the present invention is to provide a charged charge reducing device capable of preventing not only human contact but also charging caused by other sources in a form that is as reasonable as possible and that can be miniaturized.

As a result of intensive studies to solve the above problems, the present inventors have found that the above object can be achieved by making the internal structure of the main body a special structure, and have completed the present invention. Specifically, the present invention provides the following.

The present invention includes a main body portion and a conductive wire portion extending from the main body portion, and the main body portion includes a radiation generating layer including a natural ore containing a radioactive substance, a metal having a redox potential of 0 V or less, or A first metal layer containing an alloy of a metal having a redox potential of 0 V or less, a metal having a volume resistivity of 4.7 μΩ · cm or less at 0 ° C., or a metal having a volume resistivity of 5 μΩ · cm or less A second metal layer containing an alloy of the above, wherein the conductor portion has a reduction device side connection portion extending from the second metal layer and electrically connectable to an electronic device or an electric device. It is a reduction device.

The present invention also provides a radiation comprising a metal layer containing a metal having a redox potential of 0 V or less, or an alloy of a metal having a redox potential of 0 V or less, a natural ore containing a radioactive substance, and a radiation transmissive resin. The charged charge reducing member has a laminated structure in which a generation layer is laminated, and a radiation dose generated by the radiation generation layer is 0.02 μSv / h or more and 0.2 μSv / h or less.

Regarding the first charged charge reduction device, the user electrically connects the reduction device side connection portion provided in the conducting wire portion of the reduction device to an electronic device or an electrical device. This method is a method that a user can retrofit to a purchased device.

∙ Static electricity accumulates inside electronic equipment or electrical equipment, which causes electrical noise. Static electricity can obstruct the transmission of computer data or cause damage to machinery. Further, static electricity causes noise as a noise during reproduction of a sound source of an acoustic device, and causes damage to a mechanical device.

The radiation generating layer contains natural ore containing radioactive substances and generates radiation. This radiation ionizes a metal or the like having a redox potential of 0 V or less constituting the first metal layer. And the negative electric charge which arises by this ionization is sent to each part of an electronic device or an electric equipment via a 2nd metal layer and a conducting wire part. Since the electronic component group provided in the electronic device and the electric device is in an electrically connectable state as a whole, if the device of the present invention and the electronic device or the electric device are electrically connected at least at one place, the negative Can be sent to various parts of each part of the electronic device or electric device. And the negative electric charge is sent, The positive electric charge electrified by the electronic device or the electric device is reduced. At this time, the user is not required to perform any work every time the electronic device or the like is used. Further, not only charging of electronic devices or electric devices derived from human contact but also charging caused by other sources can be reduced.

This makes it possible to recover the performance of electronic equipment and electrical equipment that has been reduced by the positive charge.

The first charged charge reduction device is more reasonable in that the battery does not have to be mounted on the electronic device and the electric device, and it does not depend on external energy such as the battery. Miniaturization is also possible.

Therefore, according to the first charged charge reduction device, the user can practice retrofitting the purchased device and does not ask the user for any work every time the electronic device is used. It is possible to provide a charged charge reducing device capable of preventing charging due to the origin of the material in a form that can be miniaturized as reasonably as possible.

Regarding the second charged charge reducing member, the user attaches the charged charge reducing member to a casing in which an electronic device or an electronic component group of an electric device is accommodated. At the time of attachment, the metal layer may be attached so as to contact the surface of the housing, or the radiation generation layer may be attached so as to contact the surface of the housing. This method is a method that a user can retrofit to a purchased device.

The radiation generating layer contains natural ore containing radioactive substances and generates radiation. This radiation ionizes a metal or the like having a redox potential of 0 V or less constituting the metal layer. And the negative electric charge which arises by this ionization reduces the positive electric charge charged to the electronic device or the electric equipment. At this time, the user is not required to perform any work every time the electronic device or the like is used. Further, not only charging of electronic devices or electric devices derived from human contact but also charging caused by other sources can be reduced.

The second charged charge reducing member is more reasonable in that the battery does not have to be mounted on the electronic device and the electric device and does not depend on external energy such as the battery. Miniaturization is also possible.

Therefore, according to the second charged charge reducing member, the user can practice retrofitting the purchased device and does not ask the user for any work every time the electronic device is used, not only from human contact, It is possible to provide a charged charge reducing member capable of preventing charging caused by the origin of the material in a form that is as reasonable as possible and that can be reduced in size.

In order to ionize the metal constituting the first metal layer 12 more suitably, the lower limit of the radiation dose generated by the radiation generating layer 11 is preferably 0.02 μSv / h or more, and 0.05 μSv / h or more. It is more preferable that it is 0.1 μSv / h or more.

The upper limit of the amount of radiation generated by the radiation generating layer 11 is preferably 0.2 μSv / h or less, more preferably 0.15 μSv / h or less, and particularly preferably 0.1 μSv / h or less. preferable. By defining the upper limit of the radiation dose, the safety of using radiation can be further enhanced.

Also, the amount of natural ore equivalent to the radiation source can be reduced, leading to effective use of mineral resources and cost reduction.

In the present embodiment, the value of the radiation dose is a value including the background (dose when the natural ore is not contained in the radiation generation layer 11) when the NaI scintillation type survey meter is used.

The lower limit of the content of natural ore is not particularly limited as long as it can generate a sufficient amount of radiation to activate the substance to be activated, which is inherent in the apparatus. The lower limit of the content of the natural ore is preferably 0.01 parts by mass or more, more preferably 0.1 parts by mass or more, with respect to 100 parts by mass of the material constituting the radiation generating layer 11. It is particularly preferable that the amount is at least part by mass.

The upper limit of the content of natural ore is not particularly limited as long as the radiation dose generated by the radiation generation layer 11 can be 0.2 μSv / h or less. The upper limit of the content of the natural ore is preferably 90 parts by mass or less, more preferably 85 parts by mass or less, and 80 parts by mass or less with respect to 100 parts by mass of the material constituting the radiation generation layer 11. It is particularly preferred.

The lower limit of the thickness of the radiation generating layer 11 is not particularly limited as long as a sufficient amount of radiation can be generated to activate the substance to be activated, which is inherent in the apparatus. The lower limit of the thickness of the radiation generating layer 11 is preferably 0.01 mm or more, more preferably 0.05 mm or more, and particularly preferably 0.1 mm or more.

The upper limit of the thickness of the radiation generating layer 11 is not particularly limited. The upper limit of the thickness of the radiation generating layer 11 is preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 1 mm or less.

The radiation generating layer 11 is preferably a resin composition that is a mixture of the natural ore and a resin.

The type of resin is not particularly limited. Examples of the resin include acrylic resins, polycarbonate resins, polyester resins, polystyrene resins, polyolefin resins, vinyl chloride resins, polyimide resins, silicone resins, and copolymers based on combinations selected from these resins.

In addition, in the radiation generation layer 11, the additive generally used may be contained in the range which does not affect the invention as described in this embodiment. Examples of additives include viscosity modifiers, processing aids, stabilizers, flame retardants, disaster prevention agents, anti-aging agents, antistatic agents, ultraviolet absorbers, fillers, colorants, and foaming agents.

Although not essential, the radiation generating layer 11 is a metal powder having a redox potential of −1.5V to 0V or a metal alloy powder having a redox potential of −1.5V to 0V. It is preferable that an alloy powder having an oxidation-reduction potential of −1.5 V or more and 0 V or less as an alloy is included. Since the metal or alloy powder is contained in the radiation generating layer 11, the radiation generated in the radiation generating layer 11 collides with the metal or alloy powder to cause irregular reflection, and the radiation is the first metal. It is believed that when directed to the layer 12, the amount of radiation reflected at a specific angle of incidence and reflection with respect to the first metal layer 12 increases, which can lead to further activation of the material.

As will be described below, in order to facilitate the handling of the metal or alloy powder when preparing the radiation generating layer 11, the oxidation-reduction potential of the metal or alloy powder contained in the radiation generating layer 11 is −1. More preferably, the voltage is 0.0 V or higher, more preferably −0.75 V or higher, still more preferably −0.5 V or higher, and particularly preferably −0.4 V or higher.

By the way, in order to promote diffuse reflection of the radiation generated in the radiation generating layer 11, the particle diameter of the metal or alloy powder contained in the radiation generating layer 11 is preferably as small as possible. On the other hand, the smaller the particle size, the larger the surface area of the metal or alloy, and as a result, measures to prevent spontaneous ignition of the metal or alloy are required. In order to facilitate handling of metal or alloy powder, the radiation generating layer 11 may contain substantially no powder having a redox potential of less than −1.5 V with respect to the metal or alloy powder. preferable. More preferably, the powder having an oxidation-reduction potential of less than −1.0 V is substantially not contained, and the powder having an oxidation-reduction potential of less than −0.75 V is substantially not contained. More preferably, the powder having an oxidation-reduction potential of less than −0.5 V is more preferably not contained, and the powder having an oxidation-reduction potential of less than −0.4 V is substantially contained. It is particularly preferred that

In the present embodiment, “substantially not contained” means that when the resin composition is prepared, the powder of the metal or the alloy spontaneously ignites, and the surrounding environment including the preparation apparatus is used. It shall mean the quantity that carries the risk of affecting.

[First metal layer 12]
The first metal layer 12 is composed of a metal having a redox potential of 0 V or less, or an alloy of a metal having a redox potential of 0 V or less, and an alloy having a redox potential of 0 V or less as the alloy. Since the material constituting the first metal layer 12 is a specific material, the radiation dose generated by the radiation generation layer 11 is 0.02 μSv / h or more and 0.2 μSv / h or less, which is extremely low, The radiation generated in the radiation generation layer 11 can favorably ionize the metal or the like constituting the first metal layer 12, and the negative charge generated by the ionization is sent to each part of the vehicle, thereby positively charging the vehicle. It is considered that the electric charge can be suitably reduced.

As a metal having a redox potential of 0 V or less, lithium (−3.045 V), cesium (−2.923 V), rubidium (−2.924 V), potassium (−2.925 V), barium (−2.92 V), Strontium (-2.89V), calcium (-2.84V), sodium (-2.714V), magnesium (-2.356V), thorium (-1.90V), beryllium (-1.85V), aluminum ( −1.676V), titanium (−1.63V), zirconium (−1.534V), manganese (−1.18V), tantalum (−0.81V), zinc (−0.7626V), chromium (−0 .74V), iron (−0.44V), cadmium (−0.4025V), cobalt (−0.277V), nickel (−0.257V), tin (−0.1V) 75V), lead (-0.1263V), and the like.

In order to generate a negative charge more suitably, the oxidation-reduction potential of the metal or alloy constituting the first metal layer 12 is preferably −0.4 V or less, more preferably −1.0 V or less. , −1.5V or less is more preferable, −2.0V or less is more preferable, and −2.5V or less is particularly preferable.

In the present embodiment, the first metal layer 12 is preferably plate-shaped or foil-shaped. Since it is plate-shaped or foil-shaped, its surface area is smaller than that of powder. As a result, the metal or alloy is less likely to spontaneously ignite as compared with the powder form, so even a metal or alloy having a low redox potential can be handled relatively easily.

On the other hand, a metal having an oxidation-reduction potential exceeding 0 V is not preferable because a negative charge cannot be suitably generated unless the radiation dose generated by the radiation generation layer 11 is higher than 0.2 μSv / h.

The lower limit of the thickness of the first metal layer 12 is not particularly limited as long as a negative charge can be suitably generated by ionization of the first metal layer 12. The lower limit of the thickness of the first metal layer 12 is preferably 0.01 mm or more, more preferably 0.05 mm or more, and further preferably 0.1 mm or more.

The upper limit of the thickness of the first metal layer 12 is not particularly limited. The upper limit of the thickness of the first metal layer 12 is preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 1 mm or less.

[Second metal layer 13]
The second metal layer 13 is a metal having a volume electrical resistivity at 0 ° C. of 5 μΩ · cm or less, or an alloy of the metal, and an alloy having a volume electrical resistivity at 0 ° C. of 5 μΩ · cm or less as an alloy. It is comprised including.

It is preferable that the metal or alloy constituting the second metal layer 13 has higher conductivity than the conductivity of the metal or alloy constituting the first metal layer. In particular, the negative charge generated by ionization of the metal constituting the first metal layer 11 can be more suitably sent to each part of the vehicle via the second metal layer 13 and the conductor portion 20. For this reason, the metal or alloy constituting the second metal layer 13 is preferably as high as possible.

The volume electrical resistivity at 0 ° C. is given as an index indicating the high conductivity. And as a highly conductive metal, silver (Ag, volume electrical resistivity: 1.5 μΩ · cm), copper (Cu, volume electrical resistivity: 1.6 μΩ · cm), gold (Au, volume electrical resistivity: 2.1 μΩ · cm), aluminum (Al, volume resistivity: 2.5 μΩ · cm), beryllium (Be, volume resistivity: 2.8 μΩ · cm), calcium (Ca, volume resistivity: 3. 2 μΩ · cm), magnesium (Mg, volume resistivity: 3.9 μΩ · cm), sodium (Na, volume resistivity: 4.2 μΩ · cm), rhodium (Rh, volume resistivity: 4.3 μΩ · cm) cm), iridium (Ir, volume resistivity: 4.7 μΩ · cm), and the like.

Among them, the second metal layer 13 is formed because it has higher conductivity, and negative charges generated by ionization of the metal constituting the first metal layer 11 can be more suitably sent to each part of the vehicle. The volume electrical resistivity at 0 ° C. of the metal or alloy to be used is more preferably 4 μΩ · cm, further preferably 3 μΩ · cm or less, still more preferably 2.5 μΩ · cm or less, and 2 μΩ. -It is especially preferable that it is cm or less.

The lower limit of the thickness of the second metal layer 13 is more preferably a vehicle in which negative charges generated by ionization of the metal constituting the first metal layer 11 are transmitted via the second metal layer 13 and the conductor portion 20. There is no particular limitation as long as it can be sent to each part. The lower limit of the thickness of the second metal layer 13 is preferably 0.01 mm or more, more preferably 0.05 mm or more, and further preferably 0.1 mm or more.

The upper limit of the thickness of the second metal layer 13 is not particularly limited. The upper limit of the thickness of the second metal layer 13 is preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 1 mm or less.

[First magnet 14A and second magnet 14B]
Although not essential, the first magnet 14A is provided on the surface (one surface) of the radiation generating layer 11, and the second magnet 14B is provided on the back surface (the other surface) of the second metal layer 13. Is preferred. The first magnet 14A and the second magnet 14B face each other with the same poles.

Since the first magnet 14A and the second magnet 14B face each other with the same pole, a magnetic repulsion action occurs. Due to this magnetic repulsion action, the ability to remove static electricity inside the main body 10 can be further enhanced.

The types of the first magnet 14A and the second magnet 14B are not particularly limited, but since they are maintenance-free, the first magnet 14A and the second magnet 14B are preferably permanent magnets.

In FIG. 1, the first magnet 14 </ b> A and the second magnet 14 </ b> B face each other with N poles, but the present invention is not limited to this. The first magnet 14A and the second magnet 14B need only face each other with the same pole, but since the magnetic field lines flow from the N pole toward the S pole, in order to use the magnetic force more efficiently, It is more preferable that the N poles face each other.

[Container 15]
The radiation generating layer 11, the first metal layer 12, the second metal layer 13, the first magnet 14 </ b> A, and the second magnet 14 </ b> B) are all housed in the housing 15. The material of the container is not particularly limited.

[Conductor 20]
The conductor portion 20 extends from the second metal layer 13. And the front-end | tip 20A of the conducting wire part 20 functions as a reduction device side connection part which can be electrically connected with an electronic device or an electric device.

In this embodiment, an electronic device refers to an electrical product that applies electronic technology, and includes devices that digitally process information, devices that electrically process video, audio, and the like. Examples of electronic devices include computers, televisions, displays, audio equipment, car navigation systems, mobile phone terminals, smartphones, personal digital assistants (PDAs), game machines, CD players, DVD players, digital cameras, electronic notebooks, electronic dictionaries, Calculator, hard disk recorder, video camera, printer, radio, etc.

In addition, an electric device means a device that uses electricity in general, and examples thereof include a refrigerator, a washing machine, a vacuum cleaner, an air conditioner, an electric kettle, a lighting fixture, and a microwave oven.

The shape of the reducing device side connecting portion is not particularly limited as long as it can be electrically connected to an electronic device or an electric device. As shown in FIG. 1, it may be U-shaped. In addition, when the target device is a personal computer, the shape of the reduction device side connection portion may be a shape that can be fitted to a USB terminal provided in the computer. In addition, when the target device is an acoustic device, the shape of the reduction device side connection portion may be a pin terminal type shape that can be fitted into a cylindrical hole provided in the acoustic device.

On the other hand, the positive terminal of the battery can be cited as a place where the tip 20A of the conductor portion 20 cannot be connected. Further, the tip 20A of the conductor portion 20 cannot be connected to a metal portion directly connected to the plus terminal.

In the present embodiment, the user can electrically connect the tip 20A of the conductive wire portion 20 of the charged charge reduction device 1 to the inside of the vehicle except for the negative terminal of the battery provided in the vehicle and the positive terminal of the battery. Electrically connected to at least one of the connecting parts. This method is a method that a user can retrofit to a purchased device.

The radiation generating layer 11 includes natural ore containing a radioactive substance and generates radiation. This radiation ionizes a metal or the like constituting the first metal layer 12 with an oxidation-reduction potential of 0 V or less. And the negative electric charge which arises by this ionization is sent to each part of an electronic device or an electric device via the 2nd metal layer 13 and the conducting wire part 20. FIG. Since the electronic component group provided in the electronic device and the electric device is in an electrically connectable state as a whole, the charged charge reducing device 1 of the present embodiment and the electronic device or the electric device are electrically connected at least in one place. If connected, negative charges can be sent to various parts of each part of the electronic device or electric device. And the negative electric charge is sent, The positive electric charge electrified by the electronic device or the electric device is reduced. At this time, the user is not required to perform any work every time the electronic device or the like is used. Further, not only charging of electronic devices or electric devices derived from human contact but also charging caused by other sources can be reduced.

For example, when the electronic device is a personal computer, it is possible to prevent the power of the computer from being turned on and the operation of the computer from becoming unstable.

<Charged charge reduction device>
FIG. 7 is a schematic diagram for explaining the charged charge reducing member 101 of the second embodiment. The charged charge reducing member 101 includes at least a metal layer 111 and a radiation generation layer 112.

[Metal layer 111]
The metal layer 111 includes a metal having a redox potential of 0 V or less, or an alloy of a metal having a redox potential of 0 V or less, and an alloy having a redox potential of 0 V or less as the alloy. Since the material composing the metal layer 111 is a specific material, radiation generation is performed even though the radiation dose generated by the radiation generation layer 112 is extremely low as 0.02 μSv / h or more and 0.2 μSv / h or less. The metal or the like constituting the metal layer 111 can be suitably ionized by the radiation generated in the layer 112, and the negative charge generated by the ionization is sent to each part of the electronic device or the electric device, whereby the electronic device or the electric device It is considered that the positive charge charged in the can be suitably reduced.

In the present embodiment, the metal layer 111 is preferably plate-shaped or foil-shaped. Since it is plate-shaped or foil-shaped, its surface area is smaller than that of powder. As a result, the metal or alloy is less likely to spontaneously ignite as compared with the powder form, so even a metal or alloy having a low redox potential can be handled relatively easily.

On the other hand, a metal having an oxidation-reduction potential exceeding 0 V is not preferable because a negative charge cannot be suitably generated unless the radiation dose generated by the radiation generation layer 112 is made higher than 0.2 μSv / h.

The lower limit of the thickness of the metal layer 111 is not particularly limited as long as a negative charge can be suitably generated by ionization of the metal layer 111.

[Radiation generation layer 112]
The radiation generating layer 112 includes a natural ore containing a radioactive substance.

In order to more suitably ionize the metal constituting the metal layer 111, the lower limit of the radiation dose generated by the radiation generation layer 112 is preferably 0.02 μSv / h or more, and 0.05 μSv / h or more. More preferably, it is 0.1 μSv / h or more.

The upper limit of the radiation dose generated by the radiation generating layer 112 is preferably 0.2 μSv / h or less, more preferably 0.15 μSv / h or less, and particularly preferably 0.1 μSv / h or less. preferable. By defining the upper limit of the radiation dose, the safety of using radiation can be further enhanced.

In the present embodiment, the value of the radiation dose is assumed to be a value including the background (dose when the natural generation ore is not contained in the radiation generation layer 112) when the NaI scintillation type survey meter is used.

The lower limit of the content of natural ore is not particularly limited as long as it can generate a sufficient amount of radiation to activate the substance to be activated, which is inherent in the apparatus. The lower limit of the content of the natural ore is preferably 0.01 parts by mass or more, more preferably 0.1 parts by mass or more, with respect to 100 parts by mass of the material constituting the radiation generating layer 112. It is particularly preferable that the amount is not less than part by mass.

The upper limit of the content of natural ore is not particularly limited as long as the radiation dose generated by the radiation generation layer 112 can be 0.2 μSv / h or less. The upper limit of the content of natural ore is preferably 90 parts by mass or less, more preferably 85 parts by mass or less, and 80 parts by mass or less with respect to 100 parts by mass of the material constituting the radiation generation layer 112. It is particularly preferred.

The lower limit of the thickness of the radiation generation layer 112 is not particularly limited as long as it can generate a sufficient amount of radiation to activate the substance to be activated, which is inherent in the apparatus. The lower limit of the thickness of the radiation generating layer 112 is preferably 0.01 mm or more, more preferably 0.05 mm or more, and particularly preferably 0.1 mm or more.

The upper limit of the thickness of the radiation generating layer 112 is not particularly limited. The upper limit of the thickness of the radiation generating layer 112 is preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 1 mm or less.

The radiation generating layer 112 is preferably a resin composition that is a mixture of the natural ore and a resin.

The type of resin is not particularly limited. Examples of the resin include acrylic resins, polycarbonate resins, polyester resins, polystyrene resins, polyolefin resins, vinyl chloride resins, polyimide resins, silicone resins, and copolymers based on combinations selected from these resins. Especially, since it is excellent in flexibility, it is preferable that resin is a polycarbonate resin, a polyester resin, and a silicone resin.

Note that the radiation generating layer 112 may contain additives that are widely used as long as they do not affect the invention described in the present embodiment. Examples of additives include viscosity modifiers, processing aids, stabilizers, flame retardants, disaster prevention agents, anti-aging agents, antistatic agents, ultraviolet absorbers, fillers, colorants, and foaming agents.

Although not essential, in the radiation generation layer 112, a metal powder having a redox potential of −1.5V to 0V or a metal alloy powder having a redox potential of −1.5V to 0V. It is preferable that an alloy powder having an oxidation-reduction potential of −1.5 V or more and 0 V or less as an alloy is included. Since such a metal or alloy powder is contained in the radiation generation layer 112, the radiation generated in the radiation generation layer 112 collides with the metal or alloy powder to cause irregular reflection, and the radiation is generated in the metal layer 111. It is believed that the amount of radiation that reflects at a specific angle of incidence and reflection with respect to the metal layer 111 increases when directed to, and can result in further activation of the material.

As will be described below, in order to facilitate the handling of the metal or alloy powder in preparing the radiation generating layer 112, the oxidation-reduction potential of the metal or alloy powder contained in the radiation generating layer 112 is −1. More preferably, the voltage is 0.0 V or higher, more preferably −0.75 V or higher, still more preferably −0.5 V or higher, and particularly preferably −0.4 V or higher.

By the way, in order to promote the diffuse reflection of the radiation generated in the radiation generating layer 112, the particle diameter of the metal or alloy powder contained in the radiation generating layer 112 is preferably as small as possible. On the other hand, the smaller the particle size, the larger the surface area of the metal or alloy, and as a result, measures to prevent spontaneous ignition of the metal or alloy are required. In order to facilitate handling of the metal or alloy powder, the radiation generating layer 112 may contain substantially no powder having a redox potential of less than −1.5 V with respect to the metal or alloy powder. preferable. More preferably, the powder having an oxidation-reduction potential of less than −1.0 V is substantially not contained, and the powder having an oxidation-reduction potential of less than −0.75 V is substantially not contained. More preferably, the powder having an oxidation-reduction potential of less than −0.5 V is more preferably not contained, and the powder having an oxidation-reduction potential of less than −0.4 V is substantially contained. It is particularly preferred that

[It may be a repeating structure]
The charged charge reducing member 101 for an electronic device or an electric device may have a structure in which the metal layer 111 and the radiation generation layer 112 are repeated. That is, the charged charge reducing member 101 for an electronic device or an electric device is formed of a metal layer 111, a radiation generation layer 112, a metal layer 111, a radiation generation layer 112, a metal layer 111, a radiation generation layer 112,. The layer 111 and the radiation generation layer 112 may be repeated a plurality of times.

<Electronic equipment or electrical equipment>
The charged charge reducing member 101 of this embodiment is preferably used for an electronic device or an electric device in which a main body held in an insulated state with respect to an installation surface is positively charged with static electricity by operation of the device.

As in the first embodiment, an electronic device refers to an electrical product to which electronic technology is applied, and includes devices that digitally process information, devices that electrically process video and audio, and the like. .

The user attaches the charged charge reducing member 101 to a housing in which an electronic device or an electronic component group of an electric device is accommodated. At the time of attachment, the metal layer 111 may be attached so as to contact the surface of the housing, or the radiation generation layer 112 may be attached so as to contact the surface of the housing. This method is a method that a user can retrofit to a purchased device.

The radiation generating layer 112 includes natural ore containing a radioactive substance and generates radiation. This radiation ionizes a metal or the like constituting the metal layer 111 with a redox potential of 0 V or less. And the negative electric charge which arises by this ionization reduces the positive electric charge charged to the electronic device or the electric equipment. At this time, the user is not required to perform any work every time the electronic device or the like is used. Further, not only charging of electronic devices or electric devices derived from human contact but also charging caused by other sources can be reduced.

The charged charge reducing member 101 does not have to be equipped with a battery in electronic equipment and electrical equipment, and is more reasonable in that it does not rely on external energy such as the battery. Is also possible.

Therefore, according to the charged charge reducing member 101, the user can practice retrofitting the purchased device and does not require the user to perform any work for each use of the electronic device or the like. It is possible to provide a charged charge reducing member capable of preventing the charging caused by the above as reasonably as possible and in a form that can be reduced in size.

<Examples and Comparative Examples>
〔Example〕
Connect an analog cable between a CD player (product name: CDP-337ESD, manufactured by Sony Corporation) and a personal computer on which audio editing software (product names: WAVELAB6 and CUBASE5.1, both manufactured by Steinberg) is installed. did. The charged charge reducing members 101 having the configuration shown in FIG. 7 were attached to the analog cable at the CDOUT side and the PCIN side.

In addition, an audio converter (product name: TAC-2, manufactured by ZOOM) was connected to the personal computer, and it was possible to digitize analog voice data captured in the personal computer.

・ Set CD (44.1KHz, 16Bit, Artist: JUJU, Title: If you can be honest) to CD player and play music. The reproduced music data was A / D converted, and the converted digital data was stored in a predetermined storage area of the personal computer. In parallel, music was output from a speaker connected to a personal computer.

[Comparative example]
The reproduced music data was stored in a predetermined storage area of the personal computer by the same method as in the example except that the charged charge reducing member 101 was not attached to the analog cable.

[Evaluation]
[Evaluation 1] 3D frequency analysis 3D frequency analysis was performed on each of the music data obtained in the examples and comparative examples. The results are shown in FIG.

When comparing the two, it was confirmed that there was a great difference between the low frequency range of 25 Hz to 90 Hz and the high frequency range of 180 Hz to 2000 Hz. In these wavelength bands, when the charged charge reducing member 101 is attached as in the embodiment, the sound is finer, wider and wider than in the case where the charged charge reducing member 101 is not attached as in the comparative example. Was confirmed. In the embodiment, it can be said that it is possible to provide a solid sound by finely absorbing the sound in the entire wavelength band.

In particular, when comparing the waveforms from 70 s to 140 s after the start of reproduction at around 44 Hz, the sound source with the charged charge reduction member 101 as in the embodiment can clearly see irregularities and the volume is also clear. Yes. On the other hand, the sound source without the charged charge reducing member 101 as in the comparative example has no corrugation.

In the middle sound range, the waveform unevenness was somewhat stable in the sound source with the charged charge reducing member 101 attached as in the example. On the other hand, in the sound source in which the charged charge reducing member 101 is not mounted as in the comparative example, the corrugated irregularities were larger than in the example. It seems to limit noise and unwanted loud sounds, and as a result, affect the main melody and the ease of listening to vocals.

Also, in the high sound range, the sound source with the charged charge reducing member 101 mounted as in the embodiment stabilizes the sound volume and sound quality, and there are sharp and large sizes. In particular, the accented part of the sound source and the place with impact react strongly and draw a powerful waveform. On the other hand, the sound source without the charged charge reducing member 101 as in the comparative example has many harsh and harsh waveforms overall.

[Evaluation 2] Waveform Comparison Waveforms were compared for each of the music data obtained in the examples and comparative examples. The results are shown in FIG.

From FIG. 9, it was confirmed that the sharpness of the waveform was larger in the example than in the comparative example. It is thought that the peaks of the sound are sharply aggregated and the fluctuation width is small.

[Evaluation 3] Listening Evaluation In the examples, the high frequency range was bright and wide, and the low frequency range had a sharp impact. The mid range was very stable, so it was easy to hear the main melody and vocals, and it was a relatively stable listening experience. There is a tendency to express the dynamics and accents of the sound source faithfully and boldly, and because the listening response is different, the image of the expression itself also changes slightly. There was a sense that the sound quality of the sound source was improved rather than a change that had effect processing such as equalizer, and the sound quality was very good and it was an image that could be heard clearly.

When used as equipment, the equipment is stable and can be operated faithfully, and noise and unnecessary high-motion sounds are restricted, making it easy to play and faithful to the original sound source. In addition, connection instability and troubles peculiar to analog devices tend to be resolved.

From the above, it was confirmed that the embodiment can achieve both improvement in the quality of sound itself and stabilization of connected devices.

In this embodiment, an acoustic device is taken as an example. However, in terms of improving the charging state of an electronic device, the technology of this embodiment is applied to other electronic devices such as a personal computer. The present invention can also be applied to prevent the device from becoming difficult to turn on or the electronic device from becoming unstable. In addition, it can be applied to prevent an electronic device from malfunctioning or not starting due to a phenomenon called electrostatic breakdown in which electronic components are destroyed by static electricity.
