Abstract: PURPOSE:To improve electrooptic characteristics such as response speed and threshold voltage by providing a stage for roughing the surface of an insulating film from the specified direction and a process for subjecting the surface to a rubbing treatment from the direction opposite from the roughening direction. CONSTITUTION:The layer of a transparent electrode 2 consisting of indium oxide is formed on one surface of a transparent glass substrate 1 and a layer of a polyimide resin is then deposited as the insulating film 3 on the electrode 2 by utilizing a spinner. The insulating film is thoroughly dried and thereafter a polishing agent is sprayed thereto by a dry honing machine. The rough surface 5 having directional projections 6 is formed when the polishing agent is sprayed from the specific direction of the substrate. The projections are so formed that the sloped parts 7 thereof point the direction opposite 8 from the spraying direction. The rough surface is then subjected to the rubbing treatment by a cotton fabric roller in the opposite direction 8 in succession of the above-mentioned treatment. Two sheets of the resultant substrates 1 are prepd. and are positioned to face each other in such a manner that the rubbing directions are opposite from each other. A container is made between these substrates and a liquid crystal is injected and hermetically sealed into the container, by which the liquid crystal display element is obtd.

Title: Method and device for retapping plated thread hole
Inventor: TSUCHIYA TAKASHI
IPC: B23G5/06
Filed: 1989-04-13
Abstract: PURPOSE:To surely generate the threading motion of a tap correctly aligned to the thread streak of a plated thread hole by guiding the tap, having a chamfering part in a biting point end and clamped by a tap chuck possible to eccentrically float, to the plating thread hole of a workpiece under the action of differential thread thrust. CONSTITUTION:By setting a thread pitch of a lead screw left as different from a pitch of a retapping tap 5, while the differential thread thrust of the screw is absorbed by the compression displacement of inner and outer concentrical double coil springs 15 or 16 built in a tap chuck 31, a plated member is searched for its lower thread streak dressing the thread, thereafter the tap 5 is removed by reversing a motor. In case of this retapping action, even when the axial center of the tap 5 is a little displaced for the thread hole of a workpiece, particular biting shapes 5a, 5b, provided in the tap 5, and the tap chuck 31 generate eccentrically floating action to cause automatic aligning action for performing adequate thread dressing.

Title: Optical recording medium
Inventor: ETSUNO NAGAAKI
IPC: G11B7/2433
Filed: 1983-05-25
Abstract: PURPOSE:To provide an optical recording medium which permits writing of information thereon by laser light of a small output with high sensitivity, has excellent resistance to corrosion and withstands long-term storage by providing a thin film contg. a metal of gold or platinum group via a thin transparent film consisting of a sublimable material on a base plate. CONSTITUTION:A recording layer 2 consisting of a thin film contg. a metal of a gold or platinum group is formed via a thin film consisting of a sublimable material on a transparent plastic base plate 1 of polymethyl methacrylate or polycarbonate. Various phthalocyanines including, for example, copper phthalocyanine are usable for the sublimable material. If laser light for writing of information is irradiated to such optical recording medium, the thin metallic film heats up and softens by absorbing the laser light. The heat is transmitted to the thin film consisting of the sublimable material adjacent thereto, by which the film is evaporated to have the increased pressure. The softened thin metallic film is thus extruded and a bubble-shaped deformation is generated. The pressure increase owing to the evaporation of the sublimable material is applied in this invention in the above-mentioned way so that the definite writing by the light power smaller than in the prior art is accomplished.

Abstract: PURPOSE:To lessen the power loss, signal attenuation and increase of noise index at a high frequency by a method wherein the titled device is so constructed as to include two center conductors provided at an interval in the center axis of the metallic housing cylinder of a semi-rigid type coaxial cable and a semiconductor element each of whose electrodes is connected to the center conductor and the housing cylinder. CONSTITUTION:An e.g. semi-spherical mounting substrate 6 is installed to a part of the inner surface of the metallic housing 1 of said coaxial cable. The semiconductor element 3 such as a transistor is mounted thereon, and the input and output terminals of the element 3 are connected by bonding to both of the center conductors 2 which have been cut previously. Thereby, the coaxial cable itself comes to have amplification, rectification, and other functions. When a part of the cable having the function of low noise is connected in the neighborhood of the antenna, the signal itself increases without changing the transmission system, and accordingly the influence by the loss thereafter can be made very small.

Abstract: PURPOSE:To prevent a propeller shaft from seizure or the like by disposing a coupling member for coupling the inner ring of bearing supporting the propeller shaft with the outer ring of bearing of a reverse gear, while holding the reverse gear with the inner ring of the reverse gear bearing. CONSTITUTION:When a shifter dog 5 is adapted to mesh with the forward gear 6 side by shift operation, a propeller thrust force is generated at the advance side and transmitted to a coupling member 14 through a propeller shaft 10 and further to a gear case 12 through a bearing 17 for supporting said member 14 to move a hull. Then, a reverse gear 7 is coupled with said case 12 through the inner ring 16b of bearing 16 and the outer ring 16a coupled with said coupling member 14, so that a shaft 10 and the reverse gear 7 can rotate reolative to each other with approximately same rotational frequency as that of an engine 5 without any troubles. And since the propeller thrust force is not transmitted through the reverse gear 7 and its bearing 16, any seizure is not generated during the relative rotation of gear 7 and shaft 10.
