Filed: 1981-12-20
Abstract: PURPOSE:To prevent the current of wasteful electricity by a method in which the collector resistance of a drive element to give pulse from the resistance side of its resistance diode matrix circuit is replaced by a resistance matrix circuit resistance so as to eliminate the circuit directly leading to the ground through the collector resistance.
