Title: Injection molding machine
Inventor: SONODA YUBUN
IPC: B29C45/00
Filed: 1986-12-23
Abstract: PURPOSE:To prevent glass fiber contained in resin from getting damaged in a plunger section by retaining a check ring without a pawl component at the end of the plunger of an injection molding machine. CONSTITUTION:When a resin material for injection molding (containing glass fiber) in a stuffer 27 is stored inside the end of a barrel 20, a plunger 24 moves backward gradually. At that time, the hydraulic pressure of an injection cylinder 72 connected with the rear of the plunger 24 is minimized to prevent glass fiber from getting damaged. Then, by the rotation of the plunger 24, the resin material is homogenized. As there is no pawl component for retaining a check ring at the end of the plunger 24, the material is not stirred by the pawl component when the plunger 24 rotates, and the glass fiber contained in the material is not damaged. After a given quantity of material is measured in the barrel 20, the plunger 24 is moved forward by the injection cylinder 72 to inject the material.

Filed: 1987-12-07
Abstract: PURPOSE: To facilitate a movement by floating a hook at fork moving time by arranging means for generating the same kind of magnetism on the downward tip surface of the hook and the upward surface of a finger bar contacting with it. CONSTITUTION: A permanent magnet 11 is embedded in the tip of an upper side hook 7 of a fork 4 so that the downward surface of the hook 7 is formed as the magnetic pole surface.

IPC: G01R19/145
Filed: 1989-11-29
Abstract: PURPOSE:To discriminate a target cable and to securely specify and confirm it by detecting the magnetic field of a signal circulating current by magnetic sensors and calculating the output thereof by addition and substruction. CONSTITUTION:The magnetic field sensors A and B are arranged at the periphery of a three-phase cable 1 and the magnetic field of the signal circulating current is detected. When the magnetic field sensors A and B detect a magnetic field parallel to the sense surfaces, i.e. a horizontal magnetic field, their output voltages become maximum, so when they are installed as shown in a figure, the maximum outputs are obtained. Cables 2, 3, and 4 of respective phases are positioned centering on the axis of the cable 1 at equal intervals and at equal angles and, namely, when the magnetic field sensors A and B are arranged at a nearby 120 deg. inclined angle centering on the axis of the three-phase cable, the maximum values are outputted respectively. Then the sum and difference are calculated from the respective outputs by addition and subtraction and when they are 0 and 2, it is confirmed that the magnetic field sensors A and B detect the three-phase cable 3 where the signal circulating current flows.

Abstract: PURPOSE:To perform automatic and rapid inspection of a work by deciding the shape of the outer periphery of a work based on shape data sent from a shape scanning means during scanning of a work shape and angle data obtained by a rotation detecting means. CONSTITUTION:When a motor starts to run, a rotation signal for each of work attaching stands 28, 30, 32, and 34 from a microbeam sensor 68 is inspected by a shape scanning work deciding means 86 to decide whether a work is attached to the respective attaching stands. When the work is attached to the corresponding stand, scanning of the work is started by a shape scanning work deciding means 86, and similarly, angle data from a rotary encoder 66 is read in a shape deciding means 88. Thereafter, a work under scanning is displayed on a display board 82 for a work under scanning of a shape. Reference shape data and reference angle data for a detect-freed work prescanned by the means 88 are compared with respective data obtained from present scanning to compute a comparing result.

Title: Manufacture of metallic vapor discharge arc tube, metallic vapor discharge lamp, and metallic vapor discharge arc tube, and projection type display using metallic vapor discharge lamp
Inventor: MONJU HIDETO
IPC: G03B21/14
Filed: 1991-11-25
Abstract: PURPOSE:To maintain the light beam utilization efficiency by making ppm of the hydroxyl group contained in a fire-made glass tube a specified, or smaller than the specified value and thereby preventing proceeding of a reaction of metal halide sealed with vitreous substances and crystallization thereof. CONSTITUTION:The concentration of the hydroxyl group contained in a glass tube body 12 of an arc tube 11 is highest in the outer surface of the tubular body 12 and becomes lower toward a center of the interior thereof. When the arc tube 11 is lit, the high- concentration hydroxyl group in the outer surface is diffused into the tubular body 12 due to high temperature. The reaction between a sealed metal halide and vitreous substances of the arc tube and the crystallization thereof are thereby promoted to shorten the service life of the metallic vapor discharge tube. To avoid this, the high hydroxyl-group concentration surface layer portion in the outer surface of the tubular body 12 as fire-made is removed using at least one fabrication method selected from the group consisting of grinding, blasting, hub fabrication, ion sputtering, and etching. In this way, the hydroxyl group concentration in the tubular body 12 is made 10ppm or less, thereby obtaining a bright image plane and a high quality of display.

Abstract: PURPOSE:To reduce coating thickness and to prevent peeling and shrinkage cavity by interposing a flux in a molten state into the cavity formed of parts bodies and a core and applying centrifugal force of the specific value in gravity multiple to the molten metal of a coating material simultaneously with sealing of the molten metal. CONSTITUTION:The cylinder part of a cylinder block body 1 for a high-pressure hydraulic pump is subjected to coating. The core 2 made of graphite or mild steel for assuring the thickness of the coating layer is set and the flux 3 (borax:boric acid=7:3) to intermediate welding is packed into the cavity formed of the body 1. The coating layer is heated to a prescribed temp. in a heating furnace to a molten liquid state. The cylinder block is taken out of the furnace and is placed on a vertical type centrifugal casting machine 6 by which the molten coating metal 5 is cast and the centrifugal force of 5 to 15 gravity multiple is simultaneously applied thereto. The specific gravities of the flux and the coating metal are increased by as much as the multiplication of the gravity multiples, by which the difference in the sp. gr. is increased and, therefore, the surely substd. coating is formed. The working allowance for the coating layer is decreased in this way and the yield is improved. The decrease of the man-hours for working is possible as well.

IPC: B60C9/08
Filed: 1992-11-18
Abstract: PURPOSE:To provide a pneumatic radial tire which improves fuel consumption and uneven abrasion resistance. CONSTITUTION:The carcass line shape at internal pressure of 0.5kg/cm<2> is set at R1>= R2>=R3, where the radius of curvature on the tire equatorial face is R1, the radius of curvature at the maximum width position of a belt is R2 and the radius of curvature at the maximum width position of a tire is R3. When filled at regular internal pressure, the neighborhood of the maximum width position of a carcass is deformed as recessed inward, a portion of a shoulder part is deformed as projected toward the outside of the tire and growth of the shoulder part is increased and tension burden of the belt is increased. Thus, rigidity of the belt is increased, collapse of the belt at grounding is reduced and loss at running is reduced and the low fuel consumption is achieved. Also, as growth of the shoulder part is increased, change in the crown radius is restrained and uneven abrasion is restrained.
