Title: Liquid crystal display device
Inventor: NISHIO TETSUYA
IPC: G02F1/136
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent generation of an afterimage by providing a liquid crystal display device with an afterimage preventing alignment layer, which has a modulus of elasticity in tensile elasticity measurement higher than a specified value at a specified temperature, as an alignment layer. SOLUTION: The alignment layer is a layer to determine initial alignment of liquid crystal and is usually formed of a synthetic resin, for example of a polymer material derived from polyamide acid (molecular weight about 40,000). The alignment layer has >=2 GPa (2×109 N/m2) modulus of elasticity in dynamic tensile elasticity measurement at 55 deg.C. The alignment layer thus formed has a comparatively high modulus of elasticity, implying that behavior in an electric field of liquid crystal molecules, located in contact with the alignment layer, is not influenced by the alignment layer.  When residual images before and after applying a voltage are correspondingly related to a difference ΔT (hysteresis) generated in T(transmissivity)-Va (driving voltage) curves of a liquid crystal display device as an evaluation of a behavior of the alignment layer, the ΔT (hysteresis) is drastically reduced.

Title: Electrical component
Inventor: EBATA JUNICHI
IPC: H01H11/06
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To provide an electrical component in which the base section sides at the roots of tongue sections are always stably brought into contact with the flat surface of a holding member, without coming up from the surfaces by forces bending the tongue sections downward, even when pressing forces are applied to the sliding pieces of sliders. SOLUTION: Since an electrical component is constituted in such a way that projecting sections 1f are provided to a holding member 1 below the flat surface 1a of the member 1, the base sections 2a of sliders 2 are placed on the flat surface 1a of the member 1. At the same time, the sliders 2 are attached to the holding member 1 by engaging the end sections of tongue sections 2d of the sliders 2 with the bottoms of the projecting sections 1f, the base sections 2a at the roots of the tongue sections 2d are always stably brought into contact with the flat surface 1, even when pressing forces are applied to the sliding pieces 2b of the sliders 2, because the base sections 2a are prevented from coming up from the flat surface 1a by the forces which bend the tongue sections 2a downward.

Title: Sucker
Inventor: YOKOYAMA HIDEAKI
IPC: F16B47/00
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a sucker that is characterized by some modifications made to existent suckers for easier release. SOLUTION: A sucker 1 has an air hole 1e extending through the center of a knob 1b from a suction surface 1c to the exterior side. A separate U-shaped leaf spring 7 is fitted within a constriction 1d of the knob 1b. The leaf spring 7 is bent at such a radius of curvature as, while one end is fitted in the constriction 1d, presses the other on the upper end of the knob 1b. The latter spring end is so flatted as to close the air hole 1e. When the leaf spring 7 is fitted in position in the constriction 1d, the air hole 1e is closed to allow the sucker 1 to adhere to a flat wall 3 when pressed against it via the knob 1b. When releasing the sucker 1, the free end of the leaf spring 7 is pulled up in the face of the spring pressure to allow air to flow into a sealed space 5 via the air hole 1e now opened, which facilitates the removal of the sucker 1 from the flat wall 3.

Title: Production of thermal recording material
Inventor: MATSUMOTO TAKASHI
IPC: B41M5/30
Filed: 1987-10-27
Abstract: PURPOSE:To obtain a thermal recording material having a uniform and stable coated structure excellent in smoothness and having excellent preservability, color forming properties and adaptability to recording machines, by controlling the surface roughness Ra to within a specified region at the time of providing a protective layer on a thermal color forming layer on a base by a roll blade coating method. CONSTITUTION:The surface roughness according to JIS-B0601 of a protective layer is controlled to be not more than 1.1mum at the time of providing a protective layer on a base by a roll blade coating method in the production of a thermal recording material in which a color forming layer comprising a color former and a color reaction agent capable of a color reaction with the color former when being heated, and the protective layer comprising a polymer as a main constituent, are provided in a laminate form. When the surface roughness Ra of the protective layer is more than 1.2-1.4mum, the coating property of the protective layer becomes poor, the preservability such as plasticizer resistance is lowered, and a satisfactory dynamic sensitivity can not be obtained even by controlling the pressure with which a platen is pressed against a thermal head. Therefore, the protective layer of the thermal recording material suitably has a surface roughness Ra of not more than 1.1mum, preferably, 0.8-1.1mum.

Abstract: PROBLEM TO BE SOLVED: To easily carry a substrate by a simple constitution even if the shape or size of the substrate is changed by providing regulators for regulating the periphery of the substrate at a substrate support so as to tilt to the horizontal surface. SOLUTION: A substrate carrier support has a rectangular facing 2 at approximately the central area, facing 3 having a wider area than that of the facing 2 around this facing 2, and facing 4 having a wider area than the facing 3 round this facing. Each of these facings 2, 3, 4 is formed so as to tilt when the support is held horizontally. Thus rectangular masks of three sizes fitted to the shapes of the facings 2, 3, 4 can be set on the support with their peripheries regulated by the facings. Owing to the tilt of the facing 4, a mask 7 e.g. contacts a contact surface 4A of the facing 4 by the self wt.
