Title: Three-dimensional seal registering and collating device
Inventor: HORIUCHI TAKAHIKO
IPC: G06T7/00
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To equalize the time needed for automatic collation to a visual collating time by finding, as the degree of difference, the distance from a cinnabar seal ink image of a seal impression to be inspected to the uneven surface of a registered seal while varying the position and rotational angle, and judging that the seal is genuine when the degree of differences is less than a certain judging value. SOLUTION: An optimum position and rotational angle determining mechanism calculates the judging value used for collation while determining parameters of an optimum position and a optimum rotational angle. The calculation is repeated to gradually approximate the position and angle to the optimum position and rotational angle. Once the center and azimuth are temporarily determined, the seal impression to be inspected is placed over the registered seal. Then the distance between a cinnabar seal ink pixel P of the seal impression to be inspected and the registered seal surface having the same (x, y) with it is found. When the genuine seal neither tilts nor has a blur, the cinnabar seal ink pixel P comes into contact with the registered seal peak surface without fail and the distance and sum become 0 all over.  Therefore, the value obtained by dividing the number Q of cinnabar seal ink pixels by the distances S between all the cinnabar seal ink pixels of the seal impression to be inspected and the registered seal is regarded as an evaluation scale D.

IPC: H01L29/73
Filed: 1987-08-05
Abstract: PURPOSE:To eliminate steps between electrodes, to flatten a wiring, to prevent wire breakdown and to improve the yield rate and reliability of an integrated circuit, by forming electrodes in a recess part to the height of the surface of a substrate, filling the surrounding parts of the electrodes with an insulating layer, flattening the surface, and providing the wiring. CONSTITUTION:On a substrate 1, a subcollector layer 2, a collector layer 3, a base layer 4, an emitter layer 5 and an emitter contact layer 6 are sequentially laminated. A collector electrode C1 is formed on the exposed collector layer 2. A base electrode B1 is formed on the exposed base layer 4. Both electrodes are formed to the height of the surface of the substrate. Then, an SiO2 or Si3N4 layer 7 is grown on the entire surface of the substrate so as to cover steps. A hole is provided on the required electrodes and the surfaces of the emitter and collector layers by flattening etching. A Cu/Au wiring layer is deposited on the entire surface of the substrate so as to cover the hole part. Specified patterning is performed, and a wiring 8 is formed. In this way, the steps between the electrodes are eliminated, the wiring is flattened, wire breakdown is prevented and the yield rate and reliability of the integrated circuit can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a structure and production method of a film suitable as a barrier film to be used as a base film for a wiring layer and to provide a film forming device in which metal compd. films such as TiN having different film properties and/or orientation property can be produced with high accuracy. SOLUTION: A substrate 82 where a metal compd. film is to be formed and a metal film source 83 which constitutes the metal compd. film are disposed at a certain distance in a film forming chamber. A gas essentially comprising reactive gas N2 which reacts with the metal emitted from the metal film source is made to flow near the substrate, while a gas essentially comprising inert gas Ar is made to flow near the metal film source, so that the metal emitted from the metal film source is made to react with the reactive gas to deposit a metal compd. film on the substrate. A discharging port 87 is formed between the metal film source 83 and the substrate 82 and exhausting is performed to such a degree that the reaction gas can not reach the metal film source 83.

Title: Non-contact inflation film thickness measuring method and device
Inventor: MIHARA TOSHIAKI
IPC: G01B15/02
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To measure the thickness without arranging a radiation source and a detector in the interior by disposing a radiation source at a specified angle and a detector opposite thereto on the outside, and moving a set of both in rotation in the circumferential direction. SOLUTION: A radiation source 2 is arranged on the outside of an inflation film 1, and the angle A to a detector 3 similarly arranged on the outside opposite thereto is 20 degrees or more. The radiation 4 from the radiation source 2 is passed through the inflation film 1 two times to reach the detector 3. At this time, the radiation source 2 and the detector 3 are rotated in the circumferential direction of the inflation film 1 as indicated by arrows 5-1, 5-2, and the rotating speeds of the radiation source 2 and the detector 3 are made equal. Thus, the partial thickness of the inflation film 1 near the detector 3 can be measured. Thus, measurement is enabled without inserting a material to be measured in the inflation film 1 and only by disposing the device on the outside.

Abstract: PURPOSE:To prevent a gasket from falling off and coming up by a method wherein a flangless end of a flanged metal cylinder is forced-fitted to be fixed to a cylinder-shaped part to hold the internal diameter side of a gasket between the other end of said metal cylinder, namely the flange of the end to an axial direction output terminal and a conductive member of the other part of an external surface. CONSTITUTION:A flangeless end 5b of a flanged metal cylinder 5 is fixed by forced fitting to a cylinder-shaped part of an output side metal sealing member 1e, while at the other end the flange 5a holds down the internal diameter side of a gasket 4 from the upper surface (the output terminal side) and holds the gasket 4 by compression together with a magnet 2a or the upper surface of a yoke 3a. Accordingly the gasket 4 is surely maintained also in the cource of transport, and the like without causing an falling-off accident. The metal cylinder 5 is forced-fitted to the output side metal sealing member 1e at the end part 5b thus obtaining stabilized connection in view of microwaves, moreover without using expensive silver solder for said junction part as before and doing with a few processes.

IPC: G02F1/1335
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical system for a projection type display using three reflection type space/light modulators(SLMs). SOLUTION: Each color component is guided to one of three SLMs 38, 40, 42 through its own polarized beam spliter(PBS) cub 44, 46 or 48. In two SLMs 40, 42 out of three, image forming light is reflected from each SLM 40 or 42 and passed through each corresponding PBS 44 or 46. Two colors are recombined by using a dichroic prism 64. An image of two colors is formed by a lens 58 and projected to the surface of a screen. The 3rd SLM is arranged on a completely different route. Image forming light from the SLM 38 forms an image by a relay lens 50 of which power is almost '1' to generate an intermediate image plane. Then the intermediate image is recombined with the two color images by using the PBS 46 and the prism 64.

Title: Optical reader
Inventor: ISHIKAWA HIROSHI
IPC: G06T1/00
Filed: 1987-08-05
Abstract: PURPOSE:To prevent an adverse effect due to regular-reflection light by setting an image-formation point on a light-emitting side to a position farther than the image-formation point on a light-receiving side from the lens. CONSTITUTION:An image-formation point A on the light-emitting side, at which a light-emitting element 28 is image-formed by a lens 26 on the light-emitting side, is set to the position farther than an image-formation point B on the light-receiving side, at which a light-receiving element 29 is image-formed by a light-receiving lens 26, from the lens. Consequently, light is irradiated in a defocusing condition for a detecting surface, the proportion of regular-reflection light out of the light, which is reflected from the detecting surface and obtained by the light-receiving lens, is reduced. When a bar code, etc., are read, a possibility to detect the regular-reflection light fro a black bar is largely decreased. Thus, the level of the detecting signal of the black bar and a white bar can be stabilized.
