Title: Buffer type gas-blast circuit breaker
Inventor: KIKUTA TOSHIRO
IPC: H01H33/91
Filed: 1989-02-10
Abstract: PURPOSE:To augment gas pressure blasted to an arc by providing a pressure hole by which the inside of a driving rod and a buffer chamber are communicated together, and by switching the communicating state of a hollow part in the driving rod. CONSTITUTION:When a driving rod 8 is driven to the right hand side, an arc 19 is generated between fixed/movable arching contacts 4 and 7, and the temperature at the surroundings is increased so as for insulating gas to be pressurized high. The side of a piston 29 of a hollow part 5 is closed, and almost all of the insulating gas blows in a buffer chamber 9 via an emission passage 12 and a pressure hole 31, for the pressure in the chamber 9 to be increased. When the driving rod 8 is transferred farther to the right in the last stage of the performance of the breaker, with the hollow part 5 opened and the hole 31 closed at the same time, the insulating gas in the chamber 9 blasts the arc 19 from the emission passage 12. Pressure of the insulating gas blasted to the arc 19 is augmented, and the cutting off by the breaker can thus done in a short period of arc time.

Title: Semiconductor distributed feedback type laser device
Inventor: TADA KUNIO
IPC: H01S5/12
Filed: 1992-02-19
Abstract: PURPOSE:To enhance nonlinear operation and hereby ensure low-charp high- speed bistable operation by forming a periodic absorption layer with a semiconductor material to which no impurity is added. CONSTITUTION:A diffraction grating 7 is formed by arranging absorption layers 6 each with a composition absorbing inducted emission emitted from an active layer 4 periodically along a laser optical axis located parallely to the active layer 4. More specifically, the absorbance is altered with a period of the diffraction grating 7 along the direction of the laser optical axis. The absorption layer 6 constituting the diffraction grating 7 is formed with a material involving no impurity, i.e., a material of 5X10<17>cm<-3> or lower impurity concentration. Hereby, the absorption coefficient of the absorption layer is greatly changed with laser output to ensure greater nonlinearity. Further, hysteresis of the absorption coefficient with respect to the laser output is also increased and hence hysteresis of the laser output with respect to the injection current is also increased. Thus, the laser apparatus is utilized as an optical bistable device.

IPC: H01L21/263
Filed: 1985-02-22
Abstract: PURPOSE:To prevent the generation of defective crystal growth by a method wherein an amorphous thin film is constituted using at least two kinds of material of a dielectric thin film, which works as an electric insulator,and a high heat conducting material with which a radiating action is performed, and the heat generated by the irradiation of a laser beam is diffused not only in the depthwise direction of the sample, but also in the transverse direction. CONSTITUTION:First, after a thermal oxide film SiO2 of 200nm is thickness if formed on a single crystal silicon face 100 substrate 1, a polysilicon film 3 of 300nm is formed thereon, and the oxide film of 800nm is formed. After a part of the oxide film 4 is etched, a polysilicon layer 5 of 400nm is formed on the whole surface of a sample. When a laser irradiation is performed on the above-mentioned structure, heat is diffused in the vertical direction through the polycrystalline silicon layer 3, the difference of the apparent thermal conductivity is made smaller, and the polycrystalline silicon layer 5 begins to fuse on the whole surface of the sample. As a result, said layer is turned to excellent single crystal after irradiation of the laser beam.
