Filed: 1979-11-19
Abstract: PURPOSE:To reduce the thermal resistance of the contacting surface of radiating plate surface and a cooling unit by making the surface about 0.05-0.12mm. convex. CONSTITUTION:A radiating plate 5 and a fin 9 are made of different materials and combined randomly to cause a small clearance therebetween. The application of a joint compound to the contacting surface thereof is effective to eliminate this defect. During the long-time use thereof, however, the compound loses the function thereof because of quality change or jutting-out. If the contacting surfaces (a) of the plate 5 with a fin 9 are 0.05-0.12mm. convex, therefore, thermal resistance and the change thereof can be kept low and small respectively even though the surface of the fin 9 has a small unevenness and undulation so that a semiconductor device is improved in reliability.

Abstract: PURPOSE:To prevent paper feed inferiority and to enhance the insertion of paper in a printer by providing a means bringing an auxiliary plate brought into contact with paper feed rubber and printing paper under pressure to a pressure contact state and a separated state. CONSTITUTION:An auxiliary plate 18 is brought into contact with paper feed rubber under pressure by the force of an auxiliary plate spring 19 through printing paper 7 to perform printing. Immediately before a shuttle head 22 begins to slide in a return direction after the forward process of a shuttle head 22 is completed, an auxiliary plate driving lever 15 is moved by an auxiliary plate driving cam 16 and a pin 15-1 acts on the auxiliary plate 18 to separate said plate 18 from the paper feed rubber 4. At the time of paper feed, the auxiliary plate 18 is separated from the paper feed rubber 4 and, therefore, there is rotation shift between a paper feed shaft 3 and the paper feed rubber 4 and a ratchet clutch is certainly operated to perform accurate paper feed. When a paper feed gear 2 is shaken, a paper feed transmission gear 1 is rotated and the paper feed rubber 4 is rotated through the paper feed shaft 3. The printing paper 7 pressed to the paper feed rubber 4 by a paper press roller 5 and the auxiliary plate 18 is fed by one pitch.

Abstract: PROBLEM TO BE SOLVED: To provide a portable screen which can be rolled up compactly and carried in carrying, is made easily usable many times by affixing the screen to a perpendicular surface of a wall, partition board, etc., is lightweight and may be inexpensively manufactured. SOLUTION: This portable screen is constituted by mounting a tacky adhesive sheet 20 to be peelably affixed to the perpendicular surface 50 of a wall, partition board, etc., at a rear surface 12 of a screen film 10. The fixation force of the tacky adhesive sheet 20 to fix the sheet to the rear surface 12 of the screen film 10 is made larger than the tacky adhesive force to affix the sheet to the perpendicular surface 50 to prevent the tacky adhesive sheet 20 from being held affixed to the perpendicular surface 50 at the time of removal of the screen film 10 from the affixation to the perpendicular surface 50. A release sheet 30 or the tacky adhesive sheet 20 is formed thick and the release sheet is provided with a turn-back sheet 40 adapted to allow the repetition of coating and peeling of the release sheet 30 to and from the tacky adhesive surface 22 by mounting its one end to the release sheet 30 and mounting the other end to the rear surface of the screen film so as to allow the easy peeling of the release sheet 30 peelably adhered to the tacky adhesive sheet 20 with fingertips.

Title: Electrophotographic printer
Inventor: TAKANO YASUO
IPC: G03G21/14
Filed: 1988-06-17
Abstract: PURPOSE:To prevent the disturbance of printing by inputting and calculating the detection signal of a form detector, turning off a voltage applied to a separator for a short time before the front end of a form reaches a heat roll and a backup roll and thus stopping separating operation temporarily. CONSTITUTION:A separating operation control circuit 17 is provided and inputs and calculates the detection signals of two form detectors 10, 11 for a start side and a fixation side. Then the voltage of the separator 8 is turned off for the short time before the form 5 reaches the heat roll 13 and backup roll 14 to stop the separating operation temporarily and the form 5 is attracted to a photosensitive drum 1 while the operation is stopped. Therefore, when the form 5 reaches the fixing device, a collision force is relieved with the attracting force. Consequently, the form 5 does not vibrate abnormally owing to the shock at the time of a collision and a stable print image is obtained.

Filed: 1980-10-27
Abstract: PURPOSE:To obtain a high strength electric welded steel pipe which is less threattened with bending owing to fluctuations in climatic conditions and secular change and is suited for oil wells, etc. by subjecting the electric welded part of a steel pipe formed from a steel plate to local heat treatment in a specific temp. range. CONSTITUTION:A steel plate is formed to a tubular shape and is electrically welded. The electric welded part is subjected to local heat treatment at above the A3 transformation point and >=1,000 deg.C. The residual stress of the welded part is relieaved by this heat treatment. Particularly by the local heating of 900 deg.C. The difference between the residual stress of the welded part and the residual stress of the base metal part is virtually eliminated, and the mechanical strength distribution is made uniform in the circumferential direction of the pipe. Hence, the toughness of the welded part is improved and the preventive effect of the selective corrosion of the welded part is obtained.

Inventor: ODA KAZUYA
IPC: H04N5/345
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To reduce the measuring area of a solid-state image-pickup drive rather than an area to be read at ordinary operation and to make the simplification of a device configuration compatible with the high image quality by reading signal charges only from the measuring area, while moving the measuring area of the solid- state image-pickup device to a corner on one side by moving a substrate. SOLUTION: A control part 11 supplies a control signal corresponding to detected position data to a driving signal generation part 12. The driving signal generation part 12 generates a driving signal corresponding to the control signal from the control part 11. Corresponding to the driving signal from the driving signal generation part 12, a substrate displacing part 13 moves a substrate 103. By moving the substrate 103, the measuring area of a solid-state image-pickup device 10 is moved to a corner on one side, and signal charges are read only from this measuring area. Based on the read signal charges, information are collected. On the light-receiving plane of the solid-state image-pickup device 10, a photosensitive cell 101 is arranged and a photosensitive area in a square of several millimeters is formed.  The photosensitive cell 101 photoelectrically converts the incident light which is converged through an optical system.

Title: Method and device for inspecting pattern defect
Inventor: AOKI OSAMU
IPC: G03F1/84
Filed: 1989-06-13
Abstract: PURPOSE:To simplify the processing to detect defects and to improve the accuracy of detection by selectively extracting the defect parts by the reversal processing of resist patterns. CONSTITUTION:The resist 1C of exposed parts 30 is made into the resist soluble in alkalis if the resist film 1C formed on a substrate 1 having a metallic film 1b is subjected to a primary exposing by sing a mask 2B to be inspected. A black detect part 22 is unexposed and a white defect part 21 is soluble in alkalis. The exposed parts 30 are converted to the resist soluble in alkalis when such resist film is subjected to the pattern reversal processing. Only the defect parts 21, 22 are made into the blanked patterns if the resist film is developed after the mask pattern 2B is shifted by a repeating pitch (usually one pitch) and the resist film is subjected to the secondary exposing. The substrate 1 with which light transmits only the defect parts 21, 22 is obtd. by the etching of the metallic film 1b. The inspection is thus executed with high accuracy without requiring the intricate processing.
