Patent JP-H10242508-A (JP)
Title: Manufacture of semiconductor light emitting element
Inventor: KITA TORU
IPC: H01L33/30
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a defective thyristor structure, by diffusing Zn in the joining surface between an Si-doped n-type GaAs layer and an Si-doped p-type GaAs layer and in its vicinity. SOLUTION: After a wafer is formed by successively forming an Si-doped n-type GaAs layer and an Si-doped p-type GaAs layer on an n-type GaAs substrate by the LPE method, both Zn for diffusion and As for preventing As- extraction are set. Then, after the atmosphere in an ampule is substituted with nitrogen gas or an inert gas, the ampule is evacuated to a vacuum. Thereafter, the ampule is sealed and heat treatment is performed in a heat-treating furnace. After the Zn is diffused on the surface of the wafer in such a way, a semiconductor light emitting element is formed by forming electrodes on the wafer and dicing the wafer. Since the Zn is diffused, the carrier concentration at the p-n junction or in its vicinity does not fluctuate and the formation of a defective thyristor structure can be improved.

Title: Elevator gondola
Inventor: OOTA MASATOSHI
IPC: B66B13/28
Filed: 1978-04-05
Abstract: PURPOSE: To stop the movement of an elevator gondola, by movably supporting a threshold of the gondola and actuating a switch.  
     CONSTITUTION: When a passenger steps on the movable threshold 14, a bibration- proof rubber piece 16 is displaced and the switch 15 is actuated by a push pin 18 to  stop the movement of the elevator gondola to prevent the passenger from coming  into contact with the wall of a duct or getting his foot nipped between the duct wall  and the movable threshold. The vibration-proof rubber pieces 16 are provided  under both the ends of the threshold 14. The switch 15 is located under the central  part of the threshold. The displacement of a switchin point is thus made the same  on whichever of the ends and central part of the threshold the passenger steps. As a  result, the switch is actuated by a constant weight independently of the step position of the passenger on the threshold.
