Abstract

PURPOSE: When an oscillation circuit is constituted by a tank circuit connected serially to power and by transistor, detection means is provided at a place where effect of oscillation stop shows up. By making output of the detection means as a drive source for transistor base, breakdown of transistor is prevented.
