Abstract: PURPOSE:To sufficiently widen the flow rate region and to reduce measuring errors of the flow rate in the whole area, by making a linear enlarged wall part of a flowmeter as a common tangent of a main arch and a sub arch, and setting the radius of the main arch, the radius of the sub arch, the distance of the center of the sub arch from the jetting face of a nozzle and the distance of the center of the sub arch from the axial center of a flow path in a specific relationship. CONSTITUTION:An inner wall face 15 at an enlarged part of a flowmeter is constituted of a main arch 16 of the radius R to a jetting surface 11 of a nozzle, a linear enlarged wall part 17 connected smoothly to the main arch 16, and a sub arch 18 of the radius (r) connected to a flow part 13. The wall part 17 is a common tangent of the arches 16 and 18. Supposing that the distance between the center of the arch 18 and the jetting surface 11 in the direction of the flow path is L, and the distance between the center of the arch 18 and the axial center of tire flow path in a transverse direction of the flow path is (x), the center of the arch 16 is set so that r/R=0.5, L/R=1.5, (x)/R=(sq. rt. 3)/2 are satisfied. The center of the arch 18 is obtained thereafter. In this manner, it becomes easy to increase or decrease the scale, etc., when the area to be measured is changed.

Inventor: FUHA YOSHIO
IPC: C23C4/02
Filed: 1979-04-03
Abstract: PURPOSE:To omit grooving process for piston rings so as to mass-produce sprayed piston rings at a low cost, by heat-treating the whole outer peripheral surface of a cylinder body which is formed by piling up many piston rings so as to prevent spraying particles from adhering to the surface, then by removing surface-treated layer of only the part to be sprayed, and by spraying metal on the surface. CONSTITUTION:Piston rings 1 chamfered 5 respectively at both ends of their outer peripheral surface are piled up to form a cylindrical body 11, then the cylinder 11 is sprayed with Teflon or Fe3O4 to form a surface treated layer 6, to which hardly adhere the sprayed particles. Then only the outer peripheral surface is ground in order to expose the surface to be sprayed, and is finished to a prescribed dimension, followed by preheating and spraying 3 with metal or ceramics. In addn., the sprayed surface 3 is finished by grinding. The piston rings are manufactured at a low cost nearly equal to that of chromium-plated piston rings, moreover they have excellent scuffing resistance and galling resistance.

IPC: G03B27/62
Filed: 1990-02-21
Abstract: PURPOSE:To prevent a sheet-like original placed on an original platen glass from being deviated on the glass by providing a sheet different from an original pressure plate and a means for holding the sheet so that it can be attached to and detatched from an original placing surface. CONSTITUTION:In the case of reading the sheet-like original, the original 8 is placed on the original platen glass 7 and original deviation preventing sheets 15 and 17 are superposed on the original 8, then the projecting part of the sheet is fixed by a sheet fixing part 19. Thus, the original is prevented from being deviated by wind pressure at the time of closing the original pressure plate. In the case of reading a book-like original, the sheets 15 and 17 are detected. By making the sheets 15 and 17 transparent, the deviation of the original can be confirmed even after the sheet is placed on the original, and the position of the original 8 is easily corrected in a state where the sheet is set by forming holes 25 and 26 on an original abutting part or exposing a part of the original.

Title: Production of optical disk
Inventor: NAGAHARA YOSHIYUKI
IPC: B29D17/00
Filed: 1990-02-20
Abstract: PURPOSE:To uniformize the resin to be stuck to a substrate and to reduce the thickness of the disk by pressurizing the substrate via a plate material having elasticity from the rear surface of the substrate at the time of curing a liquid resin, thereby bringing the substrate and a stamper into tight contact with each other uniformly over the entire surface thereof. CONSTITUTION:The elastic plate material 5 having resilience is interposed between the stamper 1 and a metallic mold 2 and the surface of the stamper and the surface of the substrate are brought into tight contact with each other by pressurization even if the plane accuracy of the stamper 1 and the metallic mold 2 is slightly inferior at the time of transferring the fine patterns formed on the stamper 1 by the liquid resin 3. The stamper 1 is brought into pressurized contact with the substrate 4 after the stamper is imposed on the elastic plate material 5 and, therefore, the application of a partial strong force therebetween is obviated. The formation of the resin to an extremely small and uniform thickness is possible in this way and the tilt thereof is decreased. The problem of a deterioration in the properties of the thin film for an optical memory deposited thereon is lessened and improvement in reliability is made.

IPC: B25B27/20
Filed: 1989-02-22
Abstract: PURPOSE:To simply pull out a clip without damaging blades by providing a cap to be covered over the anchor portion of the clip on one end portion of a shank and forming the inside diameter of this cap smaller than the diameter of a clip installing hole. CONSTITUTION:As the cap 4 of a clip extractor A is covered over the anchor portion 11 of a clip 7, two detect blades 10, 10 are pressed in the direction of a shaft P reducing the diameter of the anchor portion 11. Since the inside diameter P1 of the cap 4 is smaller than the diameter (d) of the installing hole 13, the outside diameter between the lower end portions 10a, 10a of the detent blades 10, 10 becomes smaller than the diameter (d), releasing the engaged condition between the anchor portion 11 and the installing hole 13. Hence, by pulling the installing base board 8 of the clip 7 in the arrow line direction, the clip 7 can be simply pulled out of a panel 12.

Filed: 1989-02-21
Abstract: PURPOSE:To perform accurate monitor by comparing position information of the disk read point through a position sensor moving integrally with a slider with stored read-in and read-out positions to monitor the read point position. CONSTITUTION:A fixed optical scale is read by a position sensor 20 moving integrally with the slider of a pickup 2, and the read signal passing a waveform shaping circuit 30 is counted by an up/down counter 31 to detect the read point position of a disk D. This detection result is compared with read-in and read-out position information, which are stored in a RAM of a system controller and correspond to read point position information written on the disk D, to monitor the read point position, and slider driving is immediately stopped when the read point position reaches the outside of the range of read-in and read-out positions. The read point position is always accurately monitored independently of read information from the pickup 2 without an influence upon defocusing or the like of the pickup.

Title: Electronic watch
Inventor: NAKAMURA JIYUNPEI
IPC: G04G5/00
Filed: 1979-04-06
Abstract: PURPOSE:To automatically correct time at arbitrary time on an electronic watch by calculating the difference between the absolute value of the difference between a standard time signal and a counted time and a specified number when the absolute value is higher than a predetermined value. CONSTITUTION:The differences between the standard time signal externally received through registers 1, 2 and counted time signal in an electronic watch is calculated by an arithmetic unit 11, and applied to a register unit 7 consisting of 10-digit flip-flops FF71-73 and 1-digit flip-flops FF74-77. When the difference becomes in absolute value B2 30, a NAND gate 15 produces an output ''0'', while when the absolute value B2 becomes higher than 30, the NAND gate 15 produces an output ''1''. When the output of the NAND gate 15 becomes through a controller 12 ''0'', switching units 4, 9 and 3, 8 are respectively opened and closed to allow the unit 11 to calculate 60-B2. When the result of the unit 11 becomes lower than 30, a correcting unit becomes in operating state to automatically correct the time by quick feed or stop or the like of the time in response to the positive or negative information from the unit 11 and the content of the register unit 7. Therefore, it can automatically correct the time difference within + or -30sec. at arbitrary time except at the on the hour time signal.
