<P>PROBLEM TO BE SOLVED: To provide a resonance circuit capable of simplifying time and trouble required for installation, and preventing the deterioration of reliability. <P>SOLUTION: A plurality of cables 10 is annularly disposed, and one internal conductor 11 of the adjacent cables 10 and the other external conductor 12 are connected so as to carry a current. An insulation body 13 is disposed between the internal conductor 11 formed in a long shape and the external conductor 12 formed in a cylinder shape and disposing the internal conductor 11 therein. Therefore, the cables 10 annularly disposed have an inductance L, and the internal conductor 11, the external conductor 12 and the insulation body 13 of the cables 10 have a capacitance C. Consequently, an LC resonance circuit can be configured without additionally providing a capacitor, thereby simplifying time and trouble required for installing a resonance circuit 1. Furthermore, it is unnecessary to use the capacitor which may be broken, the deterioration of the reliability of the resonance circuit 1 can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
