<P>PROBLEM TO BE SOLVED: To provide a power source supplying method and a signal transmitting method capable of solving problems wherein maintenance is necessary due to vibration and shock caused by a communication cable and a power source cable of an elevator and breakdown and failure caused by rub of cables against each other. <P>SOLUTION: Radio communication and optical special modulated wave are used to eliminate use of a communication cable. In this new system called a special modulation type electromagnetic induction and power feeding system, power is supplied from the power source without using a power source cable. A special modulation type induction electromotive force transmitter 15 and a special modulation type induction electromotive force receiver 14 are used to form a complete individual charge system for charging a battery and a capacitor, and power source is thereby secured, and the power source cable is unnecessary. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
