Title: Semiconductor manufacturing apparatus
Inventor: NISHIMURA TADASHI
IPC: H01L21/20
Filed: 1982-12-18
Abstract: PURPOSE:To provide crystal layer of high quality without strain, by a method wherein a movable upper heater is formed in hook or circular arc, and bending top end part thereof is moved in the travelling direction on a semiconductor layer. CONSTITUTION:A hook-shaped upper heater 21 has a bending top end part bent at a prescribed angle with respect to the travelling center of a specimen surface. The travelling direction is set so that the top end of the heater 21 is at front side on the travelling center of the specimen surface. If the top end of the heater 21 comes to the specimen in this constitution, a part of the specimen is melted and a melting region 14 of polycrystalline Si layer becomes triangular form and the top end further travels forwards as the melting region. At rear side of the region 14, center part is solidified and pulled towards both sides thereby stress by the solidification expansion is released and the cause of polycrystallization is eliminated. Thus stress produced in recrystallization Si layer is removed and almost entire region can be made single crystal Si layer without crystal grain boundary.

Title: Photoelectric switch device
Inventor: KIKUNAGA JIYUNICHIROU
IPC: H05B37/02
Filed: 1984-10-24
Abstract: PURPOSE:To reduce the number of wirings for a photoelectric switch device and electric power consumption by controlling on and off a switching element with use of a single joint transistor which is controlled on and off by ultra- electric power of a photoelectric conversion element. CONSTITUTION:When a light beam is irraidated to a solar battery 6, the transis tor Q1 is turned on to cause the base of the transistor Q2, that is, a main switching element, in the practically open state, and a space across the emitter and collector of the transistor Q2 is made in the off-state. As a result, an excit ing current will not flow in the exciting coil of an electromagnetic switch 4 connected to an electric power source 3 even if a manual switch 2 is closed,and a lamp 5 will not light up, because the electromagnetic switch 4 is in the off- state as it is. On the other hand, if a light beam is not irradiated to the solar battery 6, the transistor Q1 is turned off, and a space across the anode A and cathode K of the single joint transistor 7 is made in the on-state, leading the transistor Q2 to be in the off-state. Accordingly a current flows in the exciting coil of the electromagnetic switch 4 when the manual switch 2 is closed, and the electromagnetic switch 4 is turned on, rendering the lamp 5 to light up.
