Abstract
A Manchester code signal is used as a communication signal to be superimposed onto an operating current. The amplitude value in the plus direction with respect to an average current value is made larger than that in the minus direction, and the time width of an 'H' level in one bit time is made smaller than that of an 'L' level so as to establish the average current value into a low level. Accordingly, it is possible to make the average current value at the time of not-communication equal to that at the time of communication, and it is also possible to establish the average current value to a low level.
