Title: Production of information recording disk
Inventor: GOTOU YASUYUKI
IPC: G11B9/06
Filed: 1981-09-30
Abstract: PURPOSE:To detect easily a shift of focus for the beam which is irradiated to a photoresist layer under a patterning process, by forming a metallic thin film on the photoresist layer before the resist layer on a substrate is exposed to light. CONSTITUTION:A photoresist layer 2 is formed on a substrate 1, and a metallic thin film 3 is formed on the layer 2 by a vacuum vapor deposition process. The film 3 is then removed selectively by means of a laser beam. After the removal of the film 3, the substrate 1 is exposed to ultraviolet rays. Thus a disk original board T is obtained after a development. The intensity is increased for the reflected light of the beam which is irradiated to the turning substrate via a lens L3 since the reflection factor of the film 3 is large. As a result, a shift of focus of the beam can be easily compensated with the reflected light which is made incident to a light detector D via a half mirror M and a lens L4.

Abstract: PURPOSE:To prolong the life for opening and closing by providing a braking member which increase the braking force to a driving member following the displacement operation of the driving member to the opening direction of a contact. CONSTITUTION:A compression coil spring (a braking member) 23 to increase the braking force to an iron core 20 as the dispacement amount of a driving member BB (the movable iron core 20 precisely) to the contact opening direction is increased, when the contact part of a seal contact AA is opened, is provided. As a result, the opening force of the contact is not reduced too much to the level to give an influence to the extinction of arc, and the restoring operation speed of the iron core 20 when the iron core 20 is restored a specific distance and reaches to a regulating position, that is, a part of a housing 24, is braked and reduced by the spring 23. Consequently, the shock of the collision at that time is moderated, an impact force transmitted to a bellows connected to a movable shaft 12 driven by a driving pin 20a fixed to the iron core 20 through an intermediate movable member 25 is also weakened, and the bellows is never hurt, so as to extend the opening and closing life.

Filed: 1987-06-24
Abstract: PURPOSE: To obtain insulation while a decrease in a heat sink is avoided by forming a large diameter section in a header mounting hole when an electronic device is secured to a heat sink plate, and partly thickly forming the periphery of the hole of an insulating plate.  
     CONSTITUTION: A resin-insulated power transistor 1 is disposed at a predetermined position of a heat sink plate 14 to bring an insulating plate 12 into contact with its surface with a header 5 directed toward the plate 14. Then, a clamper, such as a self-tapping screw member 16 is inserted from above a package 10 into a mounting hole 13, and engaged within a clamping hole 15 to be clamped on the plate 14. In this case, a tapered large-diameter section 9 is formed in the mounting hole 8 of the header 5. Thus, since an insulating plate 12 around the hole 13 is partly thickly formed, even if chips 17 generated upon engaging of the member 16 within the hole 15 are intruded to the periphery of the hole 13, an insulating gap between the chips and the surface of the header can be sufficiently obtained. As a result, it can prevent the insulation of a transistor from decreasing.

Title: Exposure device
Inventor: GO KATSUTO
IPC: H01L21/027
Filed: 1989-06-20
Abstract: PURPOSE:To efficiently smooth the integrated illuminance on the irradiated surface by controlling pulse light emission time in accordance with the scanning position detected through position detecting means so that a light source produces a light puse at the predetermined target position in the scanning of a speckle pattern. CONSTITUTION:An exposure device transfers a pattern of reticule R on a wafer W which is a member to be exposed. The speckle pattern appearing on the surface irradiated with the exposure light is scanned by an oscillating mirror 3 which oscillates with a predetermined period. The displacement amount of the mirror 3 is detected by a position detecting part 10 and is sent to a trigger controlling part 11 as a mirror position signal. Thus, the trigger controlling part 11 compares a target mirror position, determined in accordance with the exposure condition, etc., from a controller 7, with the mirror position signal, and successively sends trigger signals to a pulse laser light source 1. The light source 1 produces laser light by receiving the trigger signals, and the oscillating mirror 3 is driven in accordance with the mirror controlling signal. At that time, efficient smoothing of the exposure amount distribution can be achieved by properly displacing the oscillating mirror and controlling the movement of the exposure amount peaks in every pulse light emission so that they move with approximately equal spacings in the direction to traverse the interference fringes.

Abstract: PURPOSE:To make it possible to obtain uniform printing by eliminating the irregularity of the density on a printing surface, by engaging the leading ends of comb tooth shaped springs with both sides of a printing element group to hold a predetermined position and reducing the contact friction between printing elements. CONSTITUTION:When one end of a righthand armature 4 is attracted to a righthand magnet 6, the other end thereof presses the lateral side of the operating projection 3c of a printing element 3 to allow the printing element 3 to move forwardly and impact printing is performed. When printing operation is finished and the printing element returns, one end part of a return armature 4 is attracted to a lefthand magnet 6 and a return projection 3d is pressed by the side surface of the other end part of said armature 4 to return the printing element 3. At this time, the leading end parts of a comb tooth shaped springs 8 are engaged with the notch parts 7 provided to the side surfaces of both end parts 3a, 3a of said printing element 3 and the printing element 3 always returns to a predetermined position to hold said position. Therefore, the operating projection 3c and the return projection 3d are held to the positions capable of being just contacted with the lateral sides of the armatures 4, 4 and there is no irregularity in the pressing forces due to the armatures 4, 4 and smooth printing due to a printing surface can be performed.

Abstract: PURPOSE:To eliminate the necessity of inserting an insulator between a semiconductor element and a heat dissipating plate by setting a shortest distance between leads and a back surface of a TO-220 type entire resin-coating semiconductor element to a predetermined value or more including tolerance. CONSTITUTION:A thickness of resin is increased by setting a distance between a back surface 1 of a case and a lead 2 to (2.6mm + maximum tolerance) as a central value by a mold designing at the time of molding. Thus, the surface 1 can be mounted directly on a flat heat dissipating plate, etc., while satisfying safety standards, addition of an insulator such as a silicon sheet, etc., coping with the plate are eliminated, a cost can be reduced, and assembling properties can be improved. Since the heat dissipation is enhanced in view of performance such as an allowable loss, etc., as compared with the case where the insulator such as the sheet is added, features of an entire resin-coated 3-terminal semiconductor element can be utilized more advantageously.
