Abstract

PURPOSE: To rapidly stabilize the temperature of an constant-temperature electronic part by detecting the heat of a semiconductor and controlling a current to maintain the temperature of the semiconductor constant.
CONSTITUTION: A current is flowed through a semiconductor 1 such as a plastic power transistor or the like to heat it. This heat is detected by a heat detector 3 such as a thermistor or the like to control the current of the semiconductor so as to retain the temperature of the semiconductor constant. The heat of the semiconductor 1 can be maintained at constant temperature with constant heat at 40W50°C for 1W2 minutes. When it is covered with a heat insulating case 5, it is not affected with atmospheric change. When a crystal oscillator 4 as one of constant-temperature electronic parts is provided on the semiconductor 1, the scillator 1 may also be maintained at constant temperature.
