Title: Liquid crystal display device and its production
Inventor: OGISHIMA KIYOSHI
IPC: G02F1/1337
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent display irregularity from being recognized by subjecting a perpendicular orientation film on a substrate not only to orientation treatment in the normal orientation direction to orient the liquid crystal molecules in a specified direction but to orientation treatment in different directions from the normal orientation direction and in temporary orientation direction which does not contribute to the orientation of liquid crystal molecules. SOLUTION: Transparent electrodes 2 comprising transparent conductive thin films are formed on the inner surfaces of transparent substrates 1. Perpendicular orientation films 3 to orient the liquid crystal molecules perpendicular to the transparent substrates are formed on the transparent electrodes 2 and rubbed in four directions 7 to 10 with each rubbing direction is different from others by 45 deg.. The order of rubbing treatment is controlled in such a manner that the last rubbing direction coincides with the normal orientation direction 10. In this method, the normal orientation direction 10 is preferably selected not to overlap the temporary orientation directions 7 to 9.

Title: Balloon catheter
Inventor: NAKANO RYOJI
IPC: A61M25/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a balloon catheter which simultaneously satisfies the requirements for making it possible to transmit the pushing force applied on a proximal part to a distal part without loss, attaining the compatibility of the pushability in an axial direction even in a curved state with the flexibility required in this distal part, making the outside diameter and thickness of a catheter shaft as small as possible and imparting sufficient strength against the strong tightening of a Y-connector connected to a guide catheter to the catheter. SOLUTION: This balloon catheter is formed by providing the distal end of the catheter shaft with a balloon and connecting an adapter to the proximal end. The catheter shaft is formed by coaxially disposing a lumen tube for the guide wire into a lumen tube 5 for dilation. This lumen tube 5 for dilation is a single member formed by integrally laminating an inside layer pipe 5A consisting of a high-modulus material gradually decreased in the outside diameter from the proximal part to the distal part and an outside layer pipe 5B consisting of a low-modulus material which covers the entire part or a part thereof and is gradually decreased in the outside diameter from the proximal part to the distal part.

Title: Brace damper
Inventor: MATSUNO AKIRA
IPC: E04H9/02
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To absorb not only large vibration in a large earthquake but also comparatively small minute vibration. SOLUTION: A hydraulic damper 16 comprises a first damping force generation part caused by viscosity resistance in a valve part provided on a piston 19 by the relative displacement of a cylinder 18 and the piston 19 and a second damping force generation part caused by friction force on a friction member 22. When a pair of the friction member 22 is pushed on the outer periphery of a piston rod 20, the hydraulic damper 16 is a friction combined type damper in which damping force by friction of the friction member 22 and a piston rod 20 can be obtained. Thus, when the piston rod 20 is minutely displaced together with the piston 19, the damping force by the friction of the friction member 22 and the piston rod 20 is given to the piston rod 20. Thereby minute vibration such as traffic vibration is damped well, and a house is prevented from traffic vibration.

Abstract: PROBLEM TO BE SOLVED: To obtain a large-sized hologram capable of realizing full color reproduction in a required visual area by the use of a monochrome laser by individually exposing plural holograms, and then integrally arranging plural holograms through a connection means so as to hold two-dimensional spread. SOLUTION: Plural holograms 30 are individually exposed and then integrally arranged through the connection means so as to hold the two-dimensional spread. For example, in the case of dividing the hologram 30 into two up and down, the size of a diffusing body 24 required to satisfy the visual area of the hologram 30 after division is the size large enough to fit the outside of an area obtained by linking the viewing points 125a and 125b at both ends of the visual area 125 with both ends 30a and 30b of the hologram 30. The hologram 30 at a lower part is installed so that positional relation between a photosensitive member and the diffusing body 24 may keep the positional relation between the hologram 30 and the diffusing body 24 symmetrically with respect to a symmetry axis 70 linking a viewing point β in the center of the visual area 125 and the end 30b of the hologram 30.

Title: Piston of internal combustion engine
Inventor: TANIZAKI MASAHIRO
IPC: F16J1/00
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To prolong a span of service life in each individual cylinder of an internal combustion engine, making improvements in air supply and exhaust efficiency, and also to form the engine into being compact in size. SOLUTION: A tetragon is used in a cylinder liner (a) of an internal combustion engine, installing each of small radii (b) at the four corners, and a piston 1 uses the same type as well. In time of a crank motion, abrasion becomes increased in the crank moving direction and its counter direction of a cylinder inner wall surface by motion of the piston 1. Load is dispersed at each of longitudinal one-side surfaces of this tetragonal piston 1, reducing the abrasion, widening each tension of pressing pieces, and further, each width of airtight pieces 2 and 3 is widened as well, whereby it is made pressable up to a place being large in the degree of wear and thus engine service life may be kept longer. The form of a cylinder head is nearly turned to a tetragonal roof type.  With this, when supply and exhaust valves are installed therein as much as four in total, each individual valve surface is installable wider than ever before. In addition, since a tubular form of the cylinder liner (a) is of a square pole, a flow of air supply and exhaust is formed into a continuous current manner so that air supply and exhaust efficiency is well improvable. In the case where those of cylinders in the same piston displacement each are arranged in lines and compared with the conventional ones, and engine of this cylinder liner (a) is manufactured to be compact in size.
