Document Type and Number:
Japanese Patent JPS6132124
Kind Code:
A
Abstract:
PURPOSE:To attain minute temperature control by using the 1st and 2nd heaters to warm quickly the room to a set temperature and using only the 1st heater for temperature control after the temperature reaches the set temperature. CONSTITUTION:A transistor (TR) 30 is turned on and flip-flop 33-35 are SET. Since the temperature is lower than the set temperature, an output of a comparator 8 goes to a high level, a Qx goes to high, a TR31 is turned on, and the 2nd heater 24 is energized. Since a TR9 is turned on, the 2nd heater is energized. When the temperature reaches the setting value, an output of the comparator 8 goes to a low level and TRs 31, 9 are turned off. When an output Q3' goes to a low level, since an R3 is fixed to a low level, the Qx goes to a low level, the TR31 is fixed in the off-state and then the temperature is controlled only with the 1st heater 2.
