Filed: 1984-03-06
Abstract: PURPOSE:To shorten the light emission delay time of a stand-by semiconductor laser diode LD by performing the temperature compensation of the DC bias current of the stand-by LD and raising the current before switching to the stand-by LD is performed in case of deterioration of an in-use LD. CONSTITUTION:The temperature sensor 24 of an automatic light output control APC circuit 2' detects the temperature state of the stand-by LD and its output is connected to an analog amplifier 26 through a gate circuit 25 controlled with an LD pre-bias control signal. The amplifier 26 varies the output voltage of the sensor 24 to the output variation width of an analog amplifier 23 which compensates variation in light output by controlling the LD DC bias current when the temperature of the LD varies in a normal APC loop. The output of the amplifier 26 is connected to the base of transistor TR1 through a TR2 and a DC bias current suitable to the temperature state of the LD is flowed in a no-signal state even when the output of the amplifier 23 drops. Consequently, pulse modulation characteristics of the stand-by LD are obtained in LD switching operation without any delay of the light emission time.

Abstract: PURPOSE:To reduce the working period and the speed of revolution of a cooling fan, by differentiating the detected output from a temperature sensor, which detects the temperature of cooling water for an engine by time, and by controlling the drive of a cooling fan based on the value obtained by differentiation. CONSTITUTION:A temperature sensor 12 is arranged to a cooling water pipe 3 of an engine 1, and the detected output from said temperature sensor 12 is put into both a comparator 13 to compare the output with the predetermined, reference voltage Es, and into a differential circuit 16. When the temperature exceeds the set value theta1, the detected value also exceeds ES, and then a comparator 13 closes a switch 14a. On the other hand, the output from a differential circuit 16 is put into a control circuit 18 through a comparator 17. A switch 18a is closed when the differentiated value is positive number, that is, the time when the temperature rises, while the switch 18a is opened when the differentiated value is a negative number, that is, the time when the temperature drops. Accordingly, a cooling fan driving motor 11 is driven through a drive circuit 15, when the temperature of cooling water is above theta1 and the temperature is rising at the same time, but the fan is stopped while the temperature is dropping.

In case of <5% Ni, satisfactory strength and heat resistance are not obtd. but >15% Ni lowers the electrical conductivity. In case of <0.1% Si, high strength is not obtd. but >1.0% Si deteriorates the workability. In case of <0.1% Al, high strength is not obtd. but >3.0% Al deteriorates the workability. Sn hardly contributes toward improving the strength when added by <0.01% but >3.0% Sn deteriorates the workability and lowers the electrical conductivity.
