<p>PURPOSE:To make it difficult for an induction current to be generated in a conductor other than the objects, by arranging return transmission lines wherein return currents are made to flow on both sides of an out-going transmission line wherein an out-going current is made to flow, and forming a coil in the magnetic field generated on the periphery of the out-going transmission line by the out-going current and the return currents which flow on both sides of the out-going current. CONSTITUTION:Three transmission lines 1a, 2a, 3a are arranged at the same intervals parallel with each other, and closed at both of the ends. A transmitting power supply 4 is inserted in the central transmission line 2a, and an out-going transmission line 2 wherein an out-going current Io is made to flow is formed. The transmission lines 1a, 3a on both sides constitute returning transmission lines 1, 3. Through each of the lines 1, 3, the return current of Io/2 flows on account of the symmetry of the lies 1a, 3a. A coil 5 is divided into two parts, one divided coil 5a is arranged between one return transmission line 1 and an out-going transmission line 2, and the other divided coil 5b is arranged between the other return transmission line 3 and the out-going transmission line 2.</p> |
