Patent JP-S6481289-A (JP)
Title: Semiconductor laser
Inventor: MANNOU MASAYA
IPC: H01S5/00
Filed: 1987-09-22
Abstract: PURPOSE:To prolong the life of a visible-ray semiconductor laser and to realize its high output by a method wherein a specific strain superlattice layer is used as an end-face protective film of the visible-ray semiconductor laser in order to prevent the end face from being oxidized. CONSTITUTION:Strain superlattice layers composed of two or more kinds of II-VI group semiconductors which are transparent with regard to a laser beam are epitaxially grown as end-face protective films at end faces of a resonator formed by a chemical etching operation or a reactive ion etching operation of an AlGaAs- or an AlGaInP- based visible-ray semiconductor laser whose lattice has been matched to GaAs. These strain superlattice layers are formed by a vapor growth operation or a molecular beam growth operation. Close adherence at an interface between both is good as compared with Al2O3, SiO2 or the like; a pinhole or an uneven part does not exist on the surface of a strain superlattice, and this surface is extremely good. Especially, even when the end faces are etched faces containing a damaged part, the faces hardly cause any problem. As a result, a deterioration on th surface at the end faces is suppressed remarkably; a high output and a stable operation to continue for many hours are realized.

IPC: C22B1/20
Filed: 1993-09-24
Abstract: PURPOSE:To make it possible to form a raw material filled layer proper to the manufacture of high quality sintered ores with high productivity. CONSTITUTION:A sintering raw material 2 stored in a hopper is fed out to a slope shoot 4 from a drum feeder and charged into a pallet 6 by way of a rotor 10. The central part of the rotor 10 is supported with a support arm 13, thereby inhibiting its deflective deformation. The sintering raw material 2 is fed to a slope surface of the raw material layer as a dispersion flow which spreads over a wide area with blades 11 of the rotor 10. The rotor 10 is segmented into a central rotor 10c between the support arms 13 and an end rotor 10s outside the support arms 13 and can be rotated at each of different speeds with a built-in power transmission mechanism of the support arms 13. This construction makes it possible to stabilize filled structure of the raw material filled layer 7 without fluctuating the distance between the slope shoot 4 and the rotor 10 since the deformation of the rotor 10 can be inhibited.

Filed: 1985-10-23
Abstract: PURPOSE:To continuously print graphic patterns by providing an internal graph page buffer to store an internal graph command for graph developing CPU and developing the contents of the page buffer to a graphic bit pattern after reading them in a print-out mode. CONSTITUTION:A graph command 1 is supplied from a host computer via an interface 3 and internal graph page buffer 9 analyzes the graph command red out of a graph page buffer 8 prior to the print of a test page buffer 4 and converts it into an internal graph command for a graph developing CPU 10.

Title: Cylindrical elastic body cutting device
Inventor: YAMADA HIDEHARU
IPC: B26D3/00
Filed: 1990-09-10
Abstract: PURPOSE:To produce a disk of desired measure out of even a soft elastic body without providing it with distortion by cutting the object to be cut not in the state of being gripped by a chucking or the like but in the state of being placed on turning rollers. CONSTITUTION:A rotary round blade 23 is used as a cutting means, and an elastic body 1, an object to be cut, is placed between turning rollers 3, without being held. At the time of cutting, these turning rollers 3 are rotated, and the elastic body l placed on these rollers 3 is cut while being rotated. The whole face of the elastic body l can be thereby cut by the cutter blade 23 biting into the elastic body l only by its radius part. The cutting resistance of the rotary round blade 23 is therefore small, and also the cut face can be finished into the fine cut face since the object to be cut l is cut while being rotated.
