スタ４７のみが加熱用抵抗４３により加熱され常
に周温より定温度上昇する。 Even if the ambient temperature changes, the resistance values of heat-sensitive elements 46 and 47 such as thermistors change at the same ratio, and only the thermistor 47 is heated by the heating resistor 43, so that the temperature always rises above the ambient temperature.

一定となる。 Therefore, the voltage division ratio does not change with respect to changes in the ambient temperature, and therefore, the time it takes for the transistor 45 to reach the cut-off state is always constant regardless of whether the ambient temperature is high or low.

保つ。 At normal temperature, the thermistor resistance value is very high, and while the lamp is on, the voltage between terminals a and b is low, so no current flows beyond the voltage regulator diode 54, and the current flows through the resistor 53. is very small, and the amount of heat generated by the resistor 53 is also small, and the temperature of the thermistor 55 does not rise, so it remains in the same state.

2. Current flows through the series circuit of the resistor 53 and the voltage regulator diode 54, and the resistor 53 and the voltage regulator diode 5
4 generates heat, the constant voltage diode 54 serves as an auxiliary heater and heats the auxiliary bimetal 3b, the thermal switch is closed, enters a reheating operation, and repeats the operation. On the other hand, due to the heat generated by the resistor 53, the thermistor 5
5 is heated, and as the temperature of the thermistor increases, its resistance value decreases. When the resistance value of the thermistor 55 decreases to (voltage of the constant voltage diode 54/resistance of the thermistor)>current flowing through the resistor 53, the current of the constant voltage diode 54 becomes zero and the auxiliary bimetal is no longer heated.
