Title: Information recording medium
Inventor: MASUDA TOSHIYUKI
IPC: G11B7/2532
Filed: 1987-12-07
Abstract: PURPOSE:To improve the protection and recording sensitivity of a recording layer by covering the surface on the recording layer side of a disk substrate with a metallic film formed with ruggedness and adhering the same with non- recording regions provided in the inside and outside circumferential sides of the substrate. CONSTITUTION:The non-recording regions 14, 15 are set in the inside and outside circumferential edge parts of the central hole part 13 of the resin substrate 11 and the recording layer 16 is formed between the regions 14 and 15. The metallic film 12 which has the central part 17 and is formed with ruggedness of 1-50mum height on the surface is disposed to face the recording layer 16. This film 12 is joined to the layer 16 by a hot-melt adhesive agent in the non- recording regions 14, 15. Permeation of moisture is thus prevented by the film 12 and the recording layer is protected for a long period of time. In addition, the irregular reflection is increased by the ruggedness of the film 12 and the undesirable influence by reflection is prevented. The protection and reading sensitivity of the recording layer are, therefore, improved.

Inventor: KINOSHITA MASAHIKO
IPC: B23K26/066
Filed: 1993-12-10
Abstract: PURPOSE:To provide a laser beam machine capable of easily machining the laser beam incidence side larger than the outgoing side. CONSTITUTION:A synthetic crystal glass 11 is inserted in a laser beam transmitting hole 10 of an abrasion mask 5, and a multiple reflection film 14 where the excimer laser beam is reflected by 60% is coated on a circumferential edge part 13 on the synthetic crystal glass 11. The energy density of the excimer laser beam passing through the circumferential edge part 13 of the transmitting hole 10 becomes 40% of the energy density of the excimer laser beam passing through the center part 12 of the transmitting hole 10. Thus, a through hole corresponding to the center part 12 and a non-through hole corresponding to the circumferential edge part 13 are simultaneously machined in a nozzle plate, and a stepped nozzle can be manufactured in one process.

Abstract: PROBLEM TO BE SOLVED: To totally reduce a cost by roughly compressing the level fluctuation of reference body signals in an equipment mounted to an earth satellite, receiving in a ground equipment, then averaging the fluctuation of the reference body signals including noise and correcting object signals. SOLUTION: The DC reproducing circuit or clamp circuit 11 of the equipment 1 mounted to the earth satellite roughly compresses the DC fluctuation part of a dynamic range for input signals provided with the level fluctuation for which the output of an infrared ray detector for detecting infrared rays from a reference body and an object in a time division manner is AC amplified and an A/D converter 12 reduces quantization noise and performs transmission to the ground equipment 2. The averaging processing circuit 21 of the ground equipment 2 performs an averaging processing for removing the noise mixed in observing the reference body, corrects the error of the reference level of the video data of the object in received data and obtains the accurate video data of the object.  Thus, resources mounted to the satellite are reduced, the degree of freedom is given to processings on the ground and a generally effective image processing system is constructed.

Title: Processor for utility ticket in charged facility
Inventor: NAITO KAZUTOSHI
IPC: G07B15/00
Filed: 1988-12-08
Abstract: PURPOSE:To reutilize a utility ticket by equipping the utility ticket with a printing area and a magnetic recording part. CONSTITUTION:A vehicle to use a charged facility gives the utility ticket to a receiving person at an exit, entrance information is read by a confirming device, exit information is magnetically recorded, and a charge is calculated. At this time, while only an entrance name 1 is printed in a printing area 2 of the utility ticket, the entrance information and the exit information are magnetically recorded in the magnetic recording part. Consequently, when the utility cad is housed in a utility ticket issuing machine having the entrance name and used again, the entrance information and the exit information recorded in the preceding time are erased, and necessary input information can be recorded on the magnetic recording part by the issuing machine for a user after that. Consequently, the utility ticket can be repeatedly used, and the cost can be widely reduced.

Title: Semiconductor device
Inventor: AZUMA HIROYASU
IPC: H01L21/768
Filed: 1986-12-25
Abstract: PURPOSE:To reduce occurrence of troubles of aluminium disappearance from an aluminium wiring, by using interlayer insulating films, which are formed compositely of the following films: a vapor growth plasma nitriding film to apply compressive stress to a lower layer aluminium wiring, and a vapor growth silicon oxidizing film to apply stress in the direction opposite to the former stress, so that the stress applied to the aluminium wiring is relaxed. CONSTITUTION:A plasma silicon nitriding film and a silicon oxidizing film generally function to apply stress to a coating aluminium wiring in the directions opposite to each other. Namely, if compressive stress is applied to one silicon nitriding film, then stress is applied to the other silicon oxidizing film in the direction in which the stress is relaxed. Therefore, thickness of a vapor growth plasma nitriding film 14 is made as small as possible so as to reduce the compressive stress, and the compressive stress is balanced with the relaxing stress for three remaining silicon oxidizing films 16, 18, and 19. Thus the compressive stress applied to a first layered aluminium wiring 13 is made small enough to be almost negligible so that occurrence of a phenomenen of aluminium disappearance can be suppressed.

Title: Gasified fuel feed device for internal combustion engine
Inventor: OTAKA SHOICHI
IPC: F02D41/00
Filed: 1987-12-08
Abstract: PURPOSE:To prevent production of a fluctuation in an air-fuel ratio to the rich side and to improve exhaust emission, by a method wherein, in a device to feed gasified fuel, generated in a fuel tank, to an engine, control is performed such that the number of revolutions is increased according to an internal pressure in the fuel tank. CONSTITUTION:During running of an engine 1, it is discriminated by an ECU 5 based on various engine parameter signals whether the engine is in a given idle running state. When discrimination of YES is made, the number of idle revolutions is converged to the target number of revolutions by controlling an auxiliary air amount control valve 14 according to a deviation between the target number of idle revolutions determined according to a running state and the actual number of revolutions of the engine. In this case, it is discriminated whether an internal pressure in a fuel tank 7 detected by an internal pressure sensor 11 exceeds a given pressure or not. When discrimination of YES in which a fuel tank pressure is high and quantities of gasified fuel is present in a canister 10 is made, the target number of idle revolutions is set to a further higher value, and an intake air amount is increased.
