Abstract: PURPOSE:To prevent the deterioration or breakdown by making overcurrent not flow into a semiconductor laser by turning off current control elements at the time of current throw-in by a method wherein a photocoupler is provided between a photodetector and the current control elements. CONSTITUTION:A modulation circuit 1 modulates the semiconductor laser LD by an image signal (a). A photo diode PD is the photodetector and generates the photocurrent according to the strength of incidence of the photo output of the LD. This photocurrent is amplified in an amplifier 2, and the peak value is kept for every main scanning in a peak hold circuit 3. The output signal of the peak hold circuit 3 is compared with the reference voltage in an error amplifier 4, resulting in the amplification of the error, and then an LED drive circuit 5 drives an LED by the output signal of the error amplifier 4. The LED and a light receiving element CdS compose a photocoupler, and the photo output of the LED is inputted to the light receiving element CdS. The light receiving element CdS and a resistor R2 give base current to a transistor Tr1, the resistance value of the light receiving element CdS varies with the photo output of the LED, thus the base current of the transistor Tr1 is controlled, and accordingly the photo output of the LD is so controlled that the input signal and the reference voltage equal in the error amplifier 4.

Title: Alumina sintered material excellent in resistance to corrosion by liquid sodium
Inventor: NOSE TETSUO
IPC: B01J19/02
Filed: 1995-04-19
Abstract: PURPOSE: To obtain an alumina sintered material excellent in corrosion resistance in the environment of liquid sodium while keeping its high temperature characteristics by selecting a specific alumina sintered material. CONSTITUTION: This alumina sintered material consisting of <=0.1wt.% silicon and the rest of >=99.9wt.% purity α-alumina, and having <=5μ mean crystal grain diameter and >=98% relative density is selected. That is, since the corrosion of an alumina sintered material in liquid sodium proceeds by the reaction of silica and oxygen existing in a grain boundary phase with the liquid sodium to form Na2 SiO3 , etc., the corrosion becomes notable in the case of having <99.9wt.% purity of alumina and >0.1wt.% silicon concentration. Also, in the case of having >10μ mean crystal grain diameter, cracks are formed in the crystal grain boundaries due to the heat stress caused by an anisotropy in heat expansion coefficients to promote the corrosion in the grain boundaries.  And in the case of having <98% relative density, the liquid sodium infiltrates into the sintered material to promote the corrosion.
