Title: Reflection type screen
Inventor: YAJIMA FUMITAKA
IPC: G03B21/60
Filed: 1985-12-20
Abstract: PURPOSE:To obtain an image with a large contrast ratio by using a screen formed by providing a diffuse reflecting layer of metallic foil, etc., which has a fine projection-recess part on the surface and anisotropic diffuse reflection characteristics on the surface of a backing substrate, and forming a louver layer which is constituted at fine pitch on the surface of the screen. CONSTITUTION:The fine projection-recess part is provided on the surface of the backing substrate 1 made of resin, wood, etc., metallic foil of Al, etc., is stuck by vapor deposition, adhesion, etc., to form the diffuse reflecting layer 2 which has large anisotropic diffuse reflection characteristics, and the parallel louver layer 3 is provided on the surface, thereby constituting a reflection type screen. The louver layer 3 cuts off light whose angle is larger than an angle determined by the pitch and thickness, so the angle of visibility is also determined by the louver layer 3. Therefore, an observer is not affected when the cut-off angle of the louver layer 3 is set to 20-30 deg. above and below the perpendicular to the screen. Further, the screen gain of the diffuse reflecting layer is decreased and the diffusibility is increased to increase the right and left angle of visibility, so the angle of visibility is wide, specially, in the right-left direction even in bright lighting and a bright image is obtained.

Title: Oscillation circuit
Inventor: MATSUOKA TOSHIAKI
IPC: H03K17/95
Filed: 1991-11-01
Abstract: PURPOSE:To entirely exclude a disadvantage resulting from a change in a Q of an LC circuit A even when the Q of the LC circuit A changes due to a change in an ambient temperature. CONSTITUTION:A current of a constant current circuit B is fed to an LC circuit A and an output of the LC circuit A is subject to positive feedback amplification by using a positive feedback amplifier circuit D, then the LC circuit A is oscillated stably and continuously. When the Q of the LC circuit A changes due to ambient temperature, the loop gain of the positive feedback amplifier circuit D is adjusted by a temperature compensation circuit E having a negative temperature characteristic according to the change. As a result, the entire loop gain is made stable against the ambient temperature. Although the temperature compensation circuit E has a negative temperature characteristic, since a VD multiplier circuit is employed, the temperature coefficient of the temperature compensation circuit E is simply changed by having only to change the circuit constant.

Abstract: PROBLEM TO BE SOLVED: To provide a connector and an electric connection structure thereof capable of reducing its cost without requiring a connector by providing a tape wire capable of realizing high density of electric connection and providing a conduction route itself with its connector function. SOLUTION: A tape wire connector 20 is formed by pasting two tape wires 10 in two layers.

Title: Graphite sheet gasket member
Inventor: HIRAI KEIZO
IPC: F16J15/10
Filed: 1990-10-25
Abstract: PURPOSE:To obtain a sheet gasket member with an excellent heat resistance, an excellent sealing property, and an excellent strength, by filling a specified weight of fluororubber in expanded graphite particles, and making its powder density at a specified value or higher. CONSTITUTION:In 60 to 95wt.pt. of expanded graphite particles, 5 to 40wt.pt. of fluororubber is filled to make a graphite sheet gasket member of the powder density of 0.7kg/cm<3> or more. As the expanded graphite and the fluororubber, a generally used material is used, and as a pressure molding method, a pressing, a rolling, and the like are available with no restriction. But in the pressure molding, it is preferable to carry out the hardening of the fluororubber at the same time, and the heating is made preferably at 150 deg.C or higher. As the method to fill the fluororubber in the expanded graphite particles, a method of impregnation is preferable because the expanded graphite particles prior to molding are very fragile and weak. This graphite sheet gasket member has a strength and the sealing property much better than a conventional gasket member which consists of only the expanded graphite particles, the heat resistance is same as the conventional one, and the oilproof and the acidproof properties are also improved extensively.

Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To allow each contour pixel to impart directional code capable of expressing a smooth contour direction by using a preliminarily decided directional code. SOLUTION: Four kinds of directional codes notched at each 45 deg. for expressing horizontal, vertical, right-upward, and right-downward directional codes are decided. At first, a smoother contour direction than the quantization notch of the directional code is extracted for each contour pixel. Then, each extracted smooth contour direction is decomposed into two directional code overlap. Decomposition coefficients are applied to the two directional codes obtained as the result of decomposition, and the two directional codes are multiplied by each decomposition coefficient, and a vector sum is calculated for each contour pixel. Thus, the original contour direction can be reproduced.
