Abstract

PURPOSE: To simplify a control circuit, by providing positive chracteristic heater itself with function as a temperature sensor.
CONSTITUTION: When electricity is conducted to a positive characteristic heater 4 and temperature rises, split voltage between a and b lowers, a constant-voltage discharge tube NL is put put, a current control element SCR2 becomes non-conductive and conduction to the heater 4 is interrupted. When temperature again drops, split voltage between a and b becomes high, NL is lit, currents are excited to a secondary terminal of a pulse transformer T and the gate signals of a current control element SCR1 are obtained through a resistance R3. When SCR1 is in ON, a condenser C2 is charged, electric charge charged to the condenser C2 is discharged in the next half-cycle, the control element SCR2 is ON and electricity is conducted to the heater 4.
