Abstract: A variable magnetic field in which a power-supplying coil and a power supplying resonator exist is generated only by the power-supplying coil.
Power-supplying coils 111 and 112 each of which generates a variable magnetic field due to the supply of a variable current via a first current path 141 on one coil end 141a side and a second current path 142 on the other coil end 142a side; resonance capacitors 151 which are provided on the first current path 141 and the second current path 142; and a power-supplying coil short-circuit mechanism 1313 which is able to cause at least one of the power-supplying coils 111 and 112 to function as a power supplying resonator by allowing the end portions 141a and 142a of the first current path 141 and the second current path 142 to short-circuit with each other are provided.-

Abstract: A comparator circuit 13 compares a value of current detected by a current detector 12 with a threshold. A first signal is output if the value is determined as to be equal to or more than the threshold. A second signal is output if the value is less than the threshold. Then, a logical operation is executed based on a signal output from the comparator circuit 13 and the signal (oscillation signal, pause signal) output from a signal oscillator14. when the power-shut off condition is met; i.e., the signal from the comparator circuit 13 is the second signal and the signal from the signal oscillator 14 is the pause signal, a turn-off control signal which turns off power supply to the power-supplying module 2 is output to the oscillation output device 11, and a turn-on control signal which turns on the power supply to the power-supplying module 2 is output to the oscillation output device 11 otherwise.
Abstract translation: 比较器电路13将由电流检测器12检测到的电流的值与阈值进行比较。 如果确定该值等于或大于阈值，则输出第一信号。 如果该值小于阈值，则输出第二个信号。 然后，基于从比较器电路13输出的信号和从信号振荡器14输出的信号（振荡信号，暂停信号）来执行逻辑运算。 当电源切断条件满足时; 即来自比较器电路13的信号是第二信号并且来自信号振荡器14的信号是暂停信号，关断到供电模块2的电力供应的关断控制信号被输出到振荡输出 装置11，并且接通对供电模块2的供电的开启控制信号，否则被输出到振荡输出装置11。
