Title: Incandescent lamp
Inventor: YAMAMOTO FUMIO
IPC: H01K1/16
Filed: 1977-10-20
Abstract: PURPOSE: To improve the vibration resistance, by interposing a conductor of less deformation resistance than a filament between a lead wire and the filament to hold it.  
     CONSTITUTION: The filament 1 and a nickel plate 3 of less deformation resistance than the filament are so placed that the nickel plate 3 is interposed between the filament and the lead wire. The filament and the nickel plate are calked with the lead wire. Since the deformation resistance of the nickel plate is lower than those of the filament and the lead wire, the nickel plate is deformed to fill the opening between the filament and the lead wire. Therefore, the substantial contact area between the lead wire and the filament is increasesd and the snapping resistance of the filament is heightened

Title: Semiconductor laser device
Inventor: OOTAKI KANAME
IPC: H01S5/22
Filed: 1980-09-08
Abstract: PURPOSE:To lower the level of the threshold current in a semiconductor laser device by reducing the swidth of a fringe through avoiding restriction of the width of the fringe by the thickness of a diffusion layer, by providing a method wherein a semicondutor layer of the same conductivity type as the active layer is formed by an epitaxial growth on a surface having a V-shaped groove. CONSTITUTION:An N type AlGaAs2, GaAs active layer 3, P type AlGaAs layer 4, N type AlGaAs layer 5 and an N type GaAs layer 6 are formed on an N type GaAs substrate 1 by epitaxial growth. Then, a V-shaped groove 7a is formed to penetrate the layers 6 and 5 and to reach the layer 4 to form a P type conductive layer 11. Since the inner walls defining the V-shaped groove are inclined at an angle of 70 deg. to each other, the width D2 of the fringe formed by the end of the V-shaped groove can be reduced without fail as compared with that formed by a diffusion from the wall of the V-shaped groove. It is, therefore, possible to lower the level of the threshold current. The V-shaped groove 7a can be refilled by the growth of the P layer 11 so that a gentle recess is formed. In consequence, it is possible to form the electrode 9 without fail and, hence, the reliability of the device is improved advantageously.

Abstract: PURPOSE:To cleave a semiconductor wafer easily without generating defectives by holding the semiconductor wafer in a sandwich shape by an adhesive sheet given tension and a hold-down sheet while tilting the edge of a cutting tool to the semiconductor wafer and pushing the edge section of the cutting tool against the edge section of the wafer. CONSTITUTION:Since a semiconductor wafer W is held in a sandwich shape by an adhesive sheet 1 given specified tension and a hold-down sheet 3 keeping the state of constant tension and pushed by a cutting tool 5, large bending moment can be applied to the semiconductor wafer W on cleavage, and a chip in narrow width can be cloven easily.
