Abstract
PURPOSE: To select a random temperature and adequate temperature properly, by connecting a variable resistor for setting a desired temperature and a resistance for setting a prescribed temperature to a control circuit for a switching element controlling electric feed to a heating filament while the both can be changed over.
CONSTITUTION: In series to AC power source 1, SCR2 and heating filament 3 are connected and in parallel to them, switch 4, variable resistor 5 (resistance 6), resistance 7, signal line 8, heat-sensitive layer 9, and heating filament 3 are connected. In parallel to heat-sensitive layer 9, the series circuit of signal line 8, diode 10, diac 11, the gate and cathode of SCR2, and heating filament 3 is connected and this makes use of fluctuations of temperature of the capacity between signal line 8 and heating filament 3 as a temperature sensor. When switch 4 is placed at side A and the value of variable resistor 5 is minimum, the temperature of heating filament 3 is maximum and when the value of variable resistor 5 is maximum, the temperature is minimum. To obtain a proper temperature, the switch is changed over to side B.
