Abstract

PURPOSE: To control the generated amount of heat correctly by supplying the oscillating pulse of an intermittent high-frequency pulse oscillator to a heater.
CONSTITUTION: In this system, a rectifier 3 is connected with an electric source 4, and a heater 2 is electrified through a switching element 5 for heating an object 1. Here, the signal of a temperature detector 6 is input into an intermittent high- frequency pulse oscillator 8 to supply on-pulses to generate the necessary amount of heat in the heater 2. Besides, a high-frequency pulse oscillator 7 is composed of a pulse oscillator 7-1, the first and the second preset counter 7-2 and 7-3, an and- circuit 7-4, and a gate-circuit 7-5. The relation between the set point of the preset counter 7-3 and the heat amount of the heater is adjusted to be linear for controlling the heat amount of the heater correctly.
