摘要	PURPOSE:To control temp. with high accuracy by executing the power feed to a heater for heating a laser by on and off of pulse current conduction. CONSTITUTION:The signal of a temp. detecting element 26 is transmitted to a temp. regulating circuit 27 and the output of a power source 28 is measured by a voltage detecting circuit 29 and is transmitted to the circuit 27. The circuit 27 interrupts the electric power which the power source 28 impresses to the heater 25 on the basis of the two signals. The quantity of the heat to be generated by the heater per unit time can be decreased by conducting the pulse current in the stage of supplying electric power to the heater 25 in this case and since the generation of a delay in detection in the temp. detecting means 26 is made hard, the temp. ripple of the heater 25 is diminished. The temp. control with high accuracy is made possible by attaching the temp. regulating circuit to change over the ratio between the pulse on time and pulse off time during the conduction of the pulse current in accordance with the power source voltage to be supplied to the heater.
其他摘要	目的：控制温度。通过对加热器执行供电以通过脉冲电流传导的接通和断开来加热激光器，从而具有高精度。组成：温度的信号。检测元件26被传送到温度。调节电路27和电源28的输出由电压检测电路29测量并传送到电路27.电路27根据电源27中断电源28对加热器25施加的电功率。信号。在这种情况下，通过在向加热器25供电的阶段中传导脉冲电流并且由于在温度下产生检测延迟，可以减少每单位时间由加热器产生的热量。检测装置26变硬，即温度。加热器25的波纹减小。温度。通过附加温度可以实现高精度的控制。调节电路根据要提供给加热器的电源电压，在脉冲电流导通期间改变脉冲导通时间和脉冲关断时间之间的比率。
