Title: Automatic gas stopping valve at gas leakage
Inventor: SAKAI YASUSADA
IPC: F16K17/22
Filed: 1979-05-26
Abstract: PURPOSE: To provide a valve device which checks a gas flow when any gas leakage is detected.  
     CONSTITUTION: When a gas leakage is detected due to cracks in the pipes etc., a pressure in the outlet port 2 is decreased and a spool 6 is pushed up under a pressure in the inlet port chamber 1. Then, the head 4 integral with the spool 6 is closely contacted with the valve seat 22 to shut off the flow of the gas. When no gas leakage is detected, the spool 6 is kept still. In this case, wheather the gas leakage is occured or not is indicated by the system having a colour in the spool 6 and further having its recognition through the display window 7. In this way, when no gas leakage is detected or checked and the leverl button 10 is depressed, the lock pin 13 is lowered and the setting lever 11 is pushed out by a reaction force of the internal pressure and the spring 15, then the set lever 11 is pushed out. And when the sleeve 5 slips out from the outer surface of the crank shaft 9, the sleeve is pushed up by a reaction force of the spring 23 to cause the gas to flow into the inlet port 2 from the inlet port chamber 1 in normal status.

Title: Manufacture of integrated semiconductor laser
Inventor: SHINOZAKI KEISUKE
IPC: H01S5/00
Filed: 1988-03-23
Abstract: PURPOSE:To manufacture a semiconductor laser easily even in case where there are many stripes to be integrated, by making a distance unequal between an active area and an optical absorption area in each guided wave path. CONSTITUTION:A p-type clad layer 4 and an optical wave guide 5 are deposited in this order by a liquid phase growth method on a current blocking layer (optical absorption layer) 2 having a stripe 3 on it. When depositing the p-type clad layer 4 by the liquid phase growth method, the current blocking layer 2 near the stripe 3a in the center of a substrate is melt-etched by about 0.5mum by using a melt to grow this p-type clad layer 4 so that the melt becomes oversaturated just before completion of deposition of the p-type clad layer 4. In this manner, stages are generated on the optical absorption layer 2, resulting in formation of an integrated semiconductor layer having unequal distance between an active area and an optical absorption area in each guided wave path. This method makes it possible to manufacture a semiconductor laser even when there are many stripes to be integrated.

IPC: G06F15/02
Filed: 1986-03-26
Abstract: PURPOSE:To easily detect failure in terms of controlling and processing by conducting the fluctuation of a DC voltage in a diagnosis control action. CONSTITUTION:The electronic desktop calculator 8 is provided with a power source control mechanism 7 that causes the output voltage of a DC power source to fluctuate according to a power source control command transmitted from a main body 2 through a power source control instructing line (a). At the time of rising, the main body 2 enters an initial activation action due to the supply of a DC voltage from the control mechanism 7, and further enters a diagnosis action. By this action the main body 2 instructs the control mechanism 7 to attain a high DC voltage margin, and executes its diagnosis control action. When this action correctly ends, the main body 2 instructs a low DC voltage margin, and executes its diagnosis action. When the margin of the DC voltage is made to fluctuate in the initial diagnosis action of the computer 2, the speed of a logic action fluctuates with defective elements mixed. Accordingly an illegal action can be easily detected.
