Inventor: OKAMOTO HIYOSHI
IPC: C23C18/20
Filed: 1984-10-09
Abstract: PURPOSE:To manufacture molded goods to be plated having superior plating strength, by subjecting the plastic contg. fine-granular rubber component to injection molding by use of a specific metallic mold for injection, removing the rubber component near the surface of the obtd. molding, and plating it. CONSTITUTION:The fine-granular rubber component (1-40pts.wt.) having 0.02-10mu particle size is incorporated into the 100pts.wt. of thermoplastic. This thermoplastic is injected into the mold which has a film of composite platings made by dispersing a fluorine-contained high molecular substance to form eutectoid on the cavity surfaces thereof, to form a molding. This molding is immersed in a soln. of mixture of e.g. concd. sulfuric acid and chromic acid,so that the rubber component in the surface of the molding can be removed to obtain the roughened surface. After that, the surface is subjected to plating.

Title: Electrolytic impregnation method in molten carbonate-type fuel cell
Inventor: HOSAKA MINORU
IPC: H01M8/02
Filed: 1985-09-24
Abstract: PURPOSE:To prevent a tile from cracking, by putting a raw tape between tile- supporting layers and assembling them into a cell together and impregnating the tile-supporting layers by heating the cell. CONSTITUTION:A raw tape 8 of carbonate is put between tile-supporting layers 9 and 10, which are composed of either porous sintered plates such as ceramics or raw tapes made from tile-supporting material powder. The tile-supporting layers 9 and 10, with the raw tape 8 of carbonate put between them, are put and fixed between separators 2 and 3, into whose recessed parts an anode plate 4 and a cathode one 5 are inserted, to be assembled into a cell. Heating the cell allows organic matter to be decomposed and vaporized for removal of fat and makes cabonate to be molten for impregnating the tile-supporting layers 9 and 10. Hence, because of such a soft raw tape put between the tile- supporting layers, the tile can be prevented from cracking.

Title: Photodetector
Inventor: NISHINA SHIGEKI
IPC: H01L31/10
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a photodetector which can measure data with high accuracy by reducing the influence of the drift of the offset voltage of an operational amplifier by measuring the rate of change of the offset voltage when an optical shutter blocks light and preparing the approximate expression of the offset voltage to time, and then, obtaining the measured data by subtracting the offset voltage from the measured data. SOLUTION: A photodetector detects the drift of the offset voltage of an operational amplifier 7 measured while an optical shutter 1 is turned off. An approximate expression predicting the change of the offset is prepared from the rate of change of the offset voltage and the offset quantity predicted from the approximate expression is subtracted from measured data, and then, the results are displayed. The error contained in the measured data of the intensity of light when measurement is performed by using the approximate expression becomes less as compared with the case where the prior art phtoodetector is used. Therefore, high accuracy data can be measured by reducing the error contained in the measured data by reducing the influence of the drift of the offset voltage without prolonging the measuring time.

Filed: 1992-08-07
Abstract: PURPOSE:To reduce the thickness of this device and to improve the efficiency of highly utilizing light by forming multilayered dielectric films consisting of a high-refractive index film on a front surface side and a low-refractive index film of a rear surface side on the front surface of a reflection film. CONSTITUTION:This illumination device is of an edge light system and has a light transmission plate 12 which is disposed in parallel behind a liquid crystal display plate 11 and illuminates this plate, a light source 13 which is disposed at the end of this light transmission plate 12, the reflection film 14 which reflects the backward light forward in the light transmission plate 12 and the multilayered dielectric films 15 which are disposed on the front surface of the reflection film 14. The multilayered dielectric films 15 consist of the high-refractive index film 17 on the front surface side and the low-refractive index film 18 on the rear surface side. The light advances into the light transmission plate 12 and advances forward while repeating the total reflection within the plate when the light source 13 is triggered to emit light. After this light is diffused by the light diffusion film 16, the light illuminates the liquid crystal display plate 11. The backward light within the light transmission plate 12 is reflected forward by the dielectric films 15. Particularly the thicknesses of the respective refractive index films 17, 18 of the multilayered dielectric films 15 are set at lambda/4 the wavelength lambdaof the light and, therefore, the light reflectivity is optimized.

Title: Laser printer
Inventor: YASUI TATSUYA
IPC: G03G15/00
Filed: 1989-08-18
Abstract: PURPOSE:To rapidly shut off a laser beam and to eliminate the need for a shutter by providing a power source breaking means in the power source circuit of a modulator driving circuit and breaking the power source by the signal from an interlock switch. CONSTITUTION:The laser beam B is reflected by a mirror M 1 and is made incident on an acoustoptical modulator AOM 2. The laser beam B is diffracted if there is a high-frequency voltqage from the modulator driving circuit 30 and the laser beam B is not diffracted if there is no high-frequency voltage. The signal of the interlock switch 7 is a low level during the normal time. The circuit 30 outputs the AOM driving circuit output when the video signal rises to a high level. The laser beam B is then diffracted and is passed through a slip 4a of a shielding plate 4 to scan a dot pattern on a photosensitive drum 20. The switch 7 rises to the high level and the power source breaking means breaks the power source when a point having the possibility of allowing the laser beam B to leak to the outside is opened. There is no signal from the circuit 30 and the laser beam B is not diffracted and is shut off by the shutting plate 4 even if the video signal rises to the high level. The shutter is thus eliminated.

IPC: B65H3/44
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To appropriately take necessary measures in case a card issuing device is hindered in the operation of its new constitution, whose number of part items can be reduced without enlarging a stack of card cassettes even if a number of card cassettes are stacked. SOLUTION: In a new card issuing method which utilizes the movement of a carrier unit, whether or not the carrier unit is in a unmovable state with a card cassette drawn out is surely detected, since the movement of the carrier unit may be hindered if a path for feeding it is not secured; when the unit is not movable, the card cassette drawn out is stored to allow the movement of the carrier unit, after which the carrier unit is moved and made to perform reference point detection which is its initial action, thus enabling card issuing action to be always performed without hindrance.
