Abstract

PURPOSE: To make a control gain large by comparing a detector output signal detecting a rotation speed of a motor with a standard voltage or a standard frequency at a comparison circuit, controlling an oscillation frequency with its output error signal voltage, and by letting possess a proper mark space ration by a waste time generating circuit.
