Title: Wire-cut electrification machining metod and its device
Inventor: MATSUNO HIROAKI
IPC: B23H7/08
Filed: 1980-04-22
Abstract: PURPOSE:To increase a cross section area of wire electrode, apply tensile force of higher intensity, thus improved processing precision by elongating the cross section size of a wire electrode for a wire-cut electrification machining device in a direction where the wire electrode proceeds and shortening said size in a directon at right angle with the wire electrode. CONSTITUTION:An electrode discharge process is carried out in a processing clearance 4 between a work 2 and the electric discharge surface 3B of a wire electrode 3. An effective electric discharge processing surface represents the short diameter D2 of the wire electrode 3 opposed to a process preceeding direction B. The sizes in a position where the wire electrode 3 cross section proceeds and a direction at right angle with the said corss section represent a long diameter D1. Therefore as compared with a wire electrode with a circular cross section, a cross section area for an equal electric discharge processing is larger. For this reason, it is possible to increase the tensile force of the wire electrode 3 by the increase of the cross section area, and carry out high precision machining with reduced wire vibration. In addition, process energy supply can be increased and processing velocity be accelerated.

Title: Semiconductor luminescent device
Inventor: TABUCHI HARUHIKO
IPC: H01S5/00
Filed: 1983-03-31
Abstract: PURPOSE:To lessen the variation of oscillating wavelength and to enable to obtain a larger optical output in the titled semiconductor luminescent device by a method wherein a semiconductor substrate is formed, and an active layer, an optical waveguide path consisting of clad layers laminated in such a condition that the active layer has been interposed between the clad layers, a periodic irregularity formed in one part of the optical waveguide path, a first electrode and a second electrode are provided. CONSTITUTION:When a current I1 is flowed from a lead wire 15, an optical gain yields at the lower region of a region 9 located over an active region 5 and a laser oscillation is generated in an oscillating wavelength having least loss and a large gain, which is decided by the period of an irregularity 3. When a current I2 flowed from a lead wire 16 is increased while maintaining the condition thereof at the time oscillated from a laser intact, the amount of light to be absorbed in the active region 5 begins to drop as the current I2 is increased and an optical gain yields at this region as well at the point when the value of the current I2 has become larger than a certain value. As a result, an amplifying action is presented. If the current I1 is set at a constant and the modulation of optical output is formed in such a way as to perform through the control of the current I2, even when it is a modulating time, no variation occurs in carriers implanted in the lower part of the Zn diffusion region 9 which belongs to the region of an oscillator. As a result, the oscillating wavelength becomes a very stabilized one in the oscillating condition, etc.

Title: Manufacture of semiconductor device
Inventor: OGIUE KATSUMI
IPC: H01L21/762
Filed: 1984-03-23
Abstract: PURPOSE:To obtain a highly integrated semiconductor device by a method wherein the lateral spreading of diffusion of impurities is prevented by formation of a groove on he surface of a substrate, thereby enabling to form an oxide film isolation region having the occupation area as small as possible. CONSTITUTION:A groove is provided by performing an etching on a P type silicon wafer 1 using mask films 3 and 4, P type impurities 5 are ion-implanted, and a heat treatment is performed. As no impurities are diffused in lateral direction due to the presence of the groove on an N<+> type deposition layer 2, an N<+> type buried layer 2' having as small an occupation area as possible can be formed. An N type layer 6 is epitaxially grown, masks 7 and 8 for selective oxidization are formed, and a thermal oxidization processing is performed. As the shoulder part of the recessed part is covered by the mask films 7 and 8, the diffusion in lateral direction is very small, thereby enabling to form the silicon film 9 for isolation having a small occupation area.

Abstract: PROBLEM TO BE SOLVED: To minimize the density unevenness of a recorded image by providing a heat radiating plate in close contact with a different face from the heating element- formed face of a head substrate with plural heating elements arranged in a row, and making the contact length between the head substrate and the heat radiating plate right below the heating elements shorter than the length of the head substrate in the heating element-arranged direction. SOLUTION: A thermal head is composed of a head substrate 9 and a heat radiating plate 10, and plural heating elements 8 are aligned in a single row on the substrate 9. The heating elements 8 are formed on a chamfered part of the end face of the substrate 9, and on the rear face of the substrate 9, the heat radiating plate 10 is provided. The heat radiating plate 10 is of the projecting shape formed on the face engaged with the substrate 9 of the plate 10, and only the center of the heat radiating plate 10 is junctioned to the substrate 9. In addition, the contact length between the heat radiating plate 10 and the substrate 9 is larger than the width of a recorded image, and is smaller than the length of the substrate 9. Further, the center of the contact part is arranged in such a manner that it coincides with the center of the heating elements 8.  Thus the drop of temperatures on both end parts of the heating elements is reduced by concentrating the heat releasing channels in the center, and the density unevenness of a recorded image in a single line is reduced.
