IPC: B65H5/00
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To surely prevent feeding defect and to easily clean a sheet feed roller by forming a viscous part and a wiping off part in a sheet material. SOLUTION: One half surface of surfaces of a cleaning material (cleaning sheet) 2 is formed with a viscous part 3, and the other half surface is formed with a wiping off part 4.

Title: Frensnel lens sheet and transmission type screen
Inventor: MORISHITA TOMIHITO
IPC: G03B21/625
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce a moire by allowing the lens surface of a Frensnel lens to be constituted of the planar part of a tip part and convex parts and/or concave parts whose cross-sections are circular-arcuate shapes to eliminate deterioration of picture quality such as the lowering of luminance, the blurring of picture. SOLUTION: Since light beams to be emitted from the lens surface of the Frensnel lens 1 are diffused and brightness and darkness patterns of light beams to be formed by the Frensnel lens 1 are reduced by forming convex parts 3 and/or concave parts 4 whose cross-sections are circular-arcuate shapes on the lens surface of the Frensnel lens 1. a moire is remarkably reduced and also the visual field in the vertical direction is expanded. Moreover, phenomenons such as a picture becomes dark because luminance is lowered at a peripheral part in which a light quantity is small, the picture of a center part becomes whitish by an irregular reflection and the lowering of luminance in the center part are suppressed by diffusion of light beams in the convex parts 3 or the concave parts 4 whose cross-sections are circular-arcuate shapes.

Inventor: SONODA HIROTETSU
IPC: B62D7/14
Filed: 1989-05-01
Abstract: PURPOSE:To improve a small sharp turning property by feeding one side chamber of a cylinder for a rear-wheel steering displacement transfer control mechanism with pressure oil of supply flow rate conformed to a car speed, and making it flow back to the return side via the other side chamber from a fixed restrictor installed in a piston. CONSTITUTION:Pressure oil out of a motor pump 11 controlling a supply according to a car speed is fed to either side of cylinder double chambers 12a, 12b constituting a rear-wheel steering displacement transfer control mechanism 14, and then flows back to an oil tank 8 via the other side chamber from a fixed restrictor 13a of a piston 13. Consequently, travel of the piston 13 is selected by size of a flow rate, and steering information from the front wheel side to the rear wheel side conformed to the moving position is transmitted to a control valve 15 from a control mechanism 14 with a specified play stroke, thereby driving a rear-wheel steering power cylinder 3. Thus, improvement in controllability including a small sharp turning property or the like at time of low speed travel of a vehicle is well promotable.

Abstract: PROBLEM TO BE SOLVED: To achieve the second and subsequent press operation without any trouble by detecting a point at which an upper die is lowered and abutted on a material on a lower die by the current rise point of a servo motor, and registering the slide position where the current value is the value corresponding to the required preload value as a die height value to facilitate the trial work. SOLUTION: When a movement command signal for setting is inputted in a movement command 6 and a servo press is started, a slide 2 is slowly lowered, and an upper die mounted on the slide 2 is abutted on a material placed on a lower die. When the set current corresponding to the preload value is detected by a galvanometer 9, the slide position is detected by a position detector 8, and a servo motor 3 is automatically stopped. The detected slide position is stored, and registered in an NC control device 5 as the value corresponding to the required preload value. The registered current value is set in a motor current setting device 10 and used every time when the servo press is in the continuous stroke by the movement command 6, and the pressure is applied with the preload value corresponding to this current value.

Title: Method for driving opto-electrical device
Inventor: MAEDA TAKESHI
IPC: G02F1/136
Filed: 1990-04-27
Abstract: PURPOSE:To average the current direction of a non-linear resistor element, to extend the using life of respective elements and to make it possible to control storing characteristics by inverting and driving the selected potential of a scanning signal in each frame. CONSTITUTION:Many driving electrodes 31a, 31b are successively selected as a pair from the highest position, and during the selection period, data are charged by counter electrodes 32. In this case, the selecting potential of a scanning signal is inverted and driven in each frame. Since the current direction of a current flowing into non-linear resistor elements 34a, 34b are averaged so as not to be deflected to one direction, the using life of the non-linear resistor elements can be extended and the generation of a picture element defects can be suppressed. In addition, the charge/discharge of data can easily be controlled by inverting the non-selected potential.

Title: Production of spacer and liquid crystal display panel
Inventor: KANBAYASHI TOMIO
IPC: G02F1/1339
Filed: 1994-05-02
Abstract: PURPOSE:To enhance strength of a spacer against tension, compression and bending applied on a substrate by obtaining fine patiticles by spray drying thee resulted soln. from the reaction between a specified epoxy resin and a hardening agent in a soln. while heating. CONSTITUTION:An epoxy. resin having 60-110 deg.C softening point (BP softening point) by ring and ball test is made to react with one or more kinds of hardening agents selected from dicyane diamide and dibasic dihydrazide by heating to obtain a half-hardened epoxy resin soln. This soln. is spray dried to obtain fine particles. If the RB softening point of the epoxy resin is lower than 60 the dried epoxy resin particles easily melt, which makes difficult to obtain stable spherical particles by the spray drying method. If the softening point exceeds 100 deg.C, it becomes difficult to melt and adhere the epoxy resin between specified substrates under pressure in the assembling process of a liquid crystal display panel.
