Abstract: PURPOSE: To provide a leak preventing device for earthquake which can stop power supply when the device detects an earthquake. CONSTITUTION: When the knob section 3a of a switch 3 is pushed up while a weight body 8 is normally erected, a switching arm 4 is also raised. When the first projecting section 4b of the arm 4 reaches the retaining claw 6a of an oscillating plate 6, the projecting section 4b is caught by the claw 6a and the arm 4 is stopped. When an earthquake occurs, the weight body 8 is turned over and a chain 9 is pulled up by the weight of the body 8. As a result, the right end of the oscillating plate 18 is pulled up. Since the plate 8 rotates in the direction shown by the arrow B, the first projecting section 4b of the arm 4 is separated from the claw 6a. In addition, the left end of the arm 4 is pulled down by a spring 5 for arm and the knob section 3a of the switch 3 is also pulled down. Therefore, the switch 3 is turned off.

Abstract: PURPOSE:To prevent temperature rise of an element due to undue voltage drop at the interface by bringing an electrode into contact with a surface where more than one II-IV compound semiconductor having different conductivity type are exposed. CONSTITUTION:A p-type ZnSe layer 101 is grown on a semiconductor substrate on which II-IV compound semiconductor layers are formed using nitrogen excited in plasma as a dopant and then a Cl doped n-type ZnSe layer 102 is grown using ZnCl2 as a doping material. Subsequently, a mask is formed of photoresist, for example, on the n-type ZnSe layer 102 and an opening reaching the p-type ZnSe layer 101 is made by a specific chemical etching. Finally, a Pt/Ti/Pt/Au metal electrode 103 is formed by electron beam deposition on the p-type ZnSe layer 101 and the n-type ZnSe layer 102 in the opening. Since the current is constricted by the n-type ZnSe 102 having high thermal conductivity, heat can be dissipated effectively from the element.

IPC: H01L21/302
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To reduce the leakage current in a semiconductor laser which is provided with current constriction layers on both sides of an active layer.
