Title: Vacuum arc descaling method
Inventor: TAKEUCHI JUN
IPC: B24C1/00
Filed: 1994-03-22
Abstract: PURPOSE:To reduce initial and running costs by projecting powder and granular iron consisting essentially of iron by high-pressure air to execute a shot blasting treatment and allowing shot materials to remain on the surface of a material to be treated and subjecting this material to pickling after a vacuum arc descaling method. CONSTITUTION:The material 13 to be treated is subjected to descaling in a shot blasting device 10 then to arc discharge in a vacuum arc device 11. In succession, the material is pickled in a pickling tank 12. The currents flowing to electrodes and the potential difference thereof, magnetic field, etc., are subjected to a discharge treatment by the modes preset for every material. The parts of the oxides which are not removed by the shot blasting are thereby removed. The surface roughness is improved by the arc discharge in the vacuum. Only the removal of the remaining shot materials is executed by the pickling. The treatment of different kinds of steel with the same pickling tank is thus possible.

Title: Binarizing circuit
Inventor: KONDO HIDEYUKI
IPC: G06T1/00
Filed: 1989-03-03
Abstract: PURPOSE:To perform a proper binarizing operation by setting a binalizing level based on the value obtained by detecting the maximum and minimum values of a video signal for each scanning line. CONSTITUTION:A detection means 11 detects and holds the maximum and minimum values of a video signal for each scanning line. Based on these maximum and minimum values, a binarizing level is set by binalizing level setting means 12 and held. Based on the binarizing level, a binarizing means 13 binarizes the video signal which is later by one scanning line than the video signal that is used for setting the binarizing level. Thus the video signal is properly binarized despite the fluctuation of the video signal caused by the influence of the shading of an image pickup means, the illumination variance of a subject, etc.

Title: Electronically controlled ignition timing controller
Inventor: SASAKURA HACHIROU
IPC: F02P5/04
Filed: 1980-04-18
Abstract: PURPOSE: To make revolutional variation smaller in a range of a load change where engine combustion bvecomes unstable, by making the ignition timing a constant angle when an engine combustion instability is detected.  
     CONSTITUTION: An engine combustion condition under air inlet piping negative pressure of above about 460mmHg is detected by an air inlet negative pressure sensor 16, where engine combustion becomes unstable. Under the above condition, a CPU used for a normal control is switched-over to an updown counter 17 by means of a multiplexer. Accordingly, ignition timing is made constant by perforce by said hardware constituted pulse number counter 17. Therefore, the variation in revolution is not amplified because ignition timing is now stable, even if a revolutional variation is caused by an unstable combustion where a misfire and a good combustion alternately occur.

Title: High output semiconductor laser
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00

Abstract: PURPOSE:To lessen an optical density and increase an end breaking level, by laminating layers of; clad, optical guide, active one, second conductivity type clad in order on a substrate having a groove and making the widths of the groove in the vicinity of ends of a resonator broader than that of the inside of the resonator; besides, rendering an optical guide layer of a groove part more thicker. CONSTITUTION:A V-shaped groove is formed on an n-type GaAs substrate 1 and the end parts are patterned into broader shapes. Growth layers 2, 3, 4, 5, 6, and 7 grow one after another on the groove with liquid phase epitaxy. A clad layer 2 does not become flat at the groove part and a thick structure of an optical guide layer 3 is formed. A refractive index becomes high equivalently inside the groove and an optical waveguide mechanism is formed in the horizontal direction. As the shape of the groove 11 formed on the foregoing substrate 1 varies in the direction of a resonator, the width of the waveguide has a structure where it is wide in the vicinity of end parts and is narrow at the center. In view of the property of a liquid phase growth, the optical guide layer 3 becomes flat after its growth and the active layer 4 is converted into a uniform growth layer.
