Abstract
PURPOSE:To contrive to freely change pulse widths, quiescent widths and frequency in such a way that counts are effected by counting clock pulses up to as many as the optional set number on a time setting device, and ON and OFF time for the pulse power source are made changeable. CONSTITUTION:Clock pulses generated in an oscillating circuit 1 are inputted first for example to an OFF time setting circuit 2, and are counted by means of counters 3, 4. Output from the counters 3, 4 is selected by a change-over relay 5, and counted using a decimal counter 6. BCD signals from the decimal counter 6 are changed to decimal output by a decoder 7, then pass through a gate circuit in such a way that optional output is selected by means of a change-over relay 8, and attain to a flip flop 19 through a gate circuit. In short, the OFF time are determined by means of clock pulses as many as the product of the both numbers by means of the change-over relays 5, 8. And, when a switch element 21 is turned ON, the circuits are changed over, an ON time setting circuit 9 counts clock pulses, and controls ON time.
