(Electromagnetic wave oscillation mechanism)
The electromagnetic wave oscillating mechanism of the present invention includes an electromagnetic wave oscillating unit and a sheet-shaped fixing member to which the electromagnetic wave oscillating unit is fixed, and is used when an electromagnetic wave is generated by applying an alternating current to the electromagnetic wave oscillating unit. is there. Then, the electromagnetic wave oscillation mechanism of the present invention may optionally further include a fixing mechanism that fixes the sheet-shaped fixing member in a curved state.

Here, the electromagnetic wave oscillating unit is composed of a cable bent in a substantially rectangular shape or a cable coil having a substantially rectangular cross section orthogonal to the axial direction. Thus, if a cable bent in a substantially rectangular shape or a cable coil having a substantially rectangular cross-section orthogonal to the axial direction is used, electromagnetic waves are oscillated with high intensity by utilizing the resonance action when an alternating current is applied. can do.

Further, the electromagnetic wave oscillating unit needs to be fixed to the sheet-shaped fixing member. If the position of the cable that makes up the electromagnetic wave oscillator is misaligned, the desired resonance effect may not be obtained and it may not be possible to oscillate the electromagnetic wave of the desired intensity. If fixed to a member, the cable can be prevented from being displaced during installation and use, and electromagnetic waves can be efficiently oscillated.
The method of fixing the electromagnetic wave oscillating portion to the sheet-shaped fixing member is not particularly limited as long as it can suppress the positional displacement of the cable. For example, as shown in FIG. The method of embedding and fixing may be used, or the method of using a cable fixing means as shown in FIGS. 2 and 3 may be used.

Then, the sheet-shaped fixing member needs to be a flexible sheet-shaped member. If the sheet-shaped member is flexible, it is easy to install the electromagnetic wave oscillation mechanism on the object to be attached such as piping and remove the electromagnetic wave oscillation mechanism from the object to be attached.

Note that the flexible sheet-shaped fixing member is not particularly limited and can be formed using a material such as a resin composition or a rubber composition, but is formed using a non-conductive material. Is preferred. If a sheet-shaped fixing member made of a non-conductive material is used, the insulating property of the electromagnetic wave oscillation mechanism can be enhanced and, for example, a high surge current countermeasure function can be exerted. Therefore, the applicability of the electromagnetic wave oscillation mechanism to the attached object having conductivity can be enhanced.
Here, the volume resistivity of the sheet-shaped fixing member made of a non-conductive material is preferably 10 ¹⁰ Ω·cm or more.

Further, the fixing mechanism optionally provided is in a state where the sheet-shaped fixing member is curved, and preferably has a substantially cylindrical shape or a cross-sectional shape orthogonal to the axial direction having an arc shape (for example, a semi-arc shape or a C shape). It is fixed in a state of being curved in a tubular shape.
The fixing mechanism is not particularly limited and, for example, a hook, a hook-and-loop fastener, a button or the like can be used. The installation position of the fixing mechanism is not limited as long as it can be fixed in a state in which the sheet-shaped fixing portion is curved. For example, when the sheet-shaped fixing member is curved, the sheet-shaped fixing members engage or face each other. It can be between the edge of the fixing member and the cable that constitutes the electromagnetic wave oscillation unit.

Here, FIG. 1 shows a schematic configuration of an example of the electromagnetic wave oscillation mechanism of the present invention described above.

The embedding of the electromagnetic wave oscillating portion 11 in the sheet-shaped fixing member 12 is not particularly limited, and may be, for example, integrally formed or a plurality of flexible sheets may be formed by a known bonding method such as an adhesive or welding. This can be performed using a known method such as a method of interposing an electromagnetic wave oscillating portion between the flexible sheets when the sheet-shaped fixing member is formed by laminating the sheets.

Further, according to the electromagnetic wave oscillation mechanism 10, since the electromagnetic wave oscillation unit 11 is composed of a cable bent into a substantially rectangular shape, it is possible to oscillate the electromagnetic wave with high intensity by utilizing the resonance action when an alternating current is applied. Further, in the electromagnetic wave oscillation mechanism 10, since the electromagnetic wave oscillation part 11 is fixed to the sheet-shaped fixing member 12, the cable 11a is prevented from being displaced during installation and use, and electromagnetic waves are efficiently oscillated. be able to.

Further, in the electromagnetic wave oscillation mechanism 10, since the electromagnetic wave oscillation part 11 is embedded in the sheet-shaped fixing member 12, it is possible to prevent the electromagnetic wave oscillation part 11 from being deteriorated by moisture or corrosive gas existing in the surrounding environment. You can

When the sheet-shaped fixing member 12 that embeds the electromagnetic wave oscillation unit 11 is made of a non-conductive material, the insulating property of the electromagnetic wave oscillation mechanism 10 is increased, and the electromagnetic wave oscillation mechanism 10 with respect to the attached object having conductivity is improved. Applicability can be increased.

Further, FIG. 2 shows a schematic configuration of another example of the electromagnetic wave oscillation mechanism of the present invention described above. As shown in a perspective view of FIG. 2A and a sectional view taken along line II-II of FIG. 2A in FIG. 2B, an electromagnetic wave oscillation mechanism 10A according to an example of the present invention has an axial direction ( The electromagnetic wave oscillating unit 11 including a cable coil formed by winding a cable 11a so that a cross section orthogonal to the main surface of the sheet-shaped fixing member 12) has a rectangular shape with rounded corners located at four corners.

There is. Specifically, as shown in FIG. 2B, the electromagnetic wave oscillating unit 11 binds the cables 11a forming the electromagnetic wave oscillating unit 11 with the binding wire 14a and the cables 11a bound with the binding wire 14a. By fixing the sheet-shaped fixing member 12 with the band 14b, the sheet-shaped fixing member 12 is fixed on one surface (upper side in FIG. 2B).

The cable fixing means 14 for fixing the electromagnetic wave oscillating portion 11 on one surface of the sheet-like fixing member 12 is bundled like the electromagnetic wave oscillating mechanism 10B showing a cross section at the same position in FIG. 2B. It may be configured only with the band 14b.

Further, according to the electromagnetic wave oscillation mechanisms 10A and 10B, since the electromagnetic wave oscillation unit 11 is composed of a cable coil having a substantially rectangular cross section orthogonal to the axial direction, the resonance action is utilized when an alternating current is passed. Electromagnetic waves can be oscillated with high intensity. Further, in the electromagnetic wave oscillation mechanisms 10A and 10B, since the electromagnetic wave oscillation unit 11 is fixed to the sheet-shaped fixing member 12, the cable 11a is prevented from being displaced during installation and use, and the electromagnetic waves are efficiently emitted. Can be oscillated.

Furthermore, in the electromagnetic wave oscillation mechanisms 10A and 10B, the electromagnetic wave oscillation part 11 is fixed on one surface of the sheet-shaped fixing member 12, and the electromagnetic wave oscillation part 11 can be easily removed from the sheet-shaped fixing member 12, Even when one of the electromagnetic wave oscillation unit 11 and the sheet-shaped fixing member 12 is deteriorated or damaged, the other can be easily reused.

When the sheet-shaped fixing member 12 is made of a non-conductive material, the insulating properties of the electromagnetic wave oscillation mechanisms 10A and 10B are enhanced, and the applicability of the electromagnetic wave oscillation mechanisms 10A and 10B to a conductive object to be attached is enhanced. be able to.
