Title: Dial device for time switch
Inventor: MUROI HIROAKI
IPC: H01H43/06
Filed: 1988-07-26
Abstract: PURPOSE:To prevent the jolting of a dial on the driven side by forming circular arc- shaped recessed faces centering the rotation center of a pin wheel on the periphery between adjacent slots in the peripheral direction of a hole groove wheel and forming circular arc-shaped protruded faces to be coupled with the recessed faces on the pin wheel. CONSTITUTION:A pin wheel 21 rotated interlockingly with a dial 11 on the driving side and protruded with pins 21b on the periphery and a hole groove wheel 22 formed with multiple slots 22a to be engaged with the pins 11b of the pin wheel 21 on the periphery and rotating a dial 23 on the driven side are inserted between a pair of the dials 11 and 23. Circular arc-shaped recessed faces 22c centering the rotation center of the pin wheel 21 are formed on the periphery between adjacent slots 22a in the peripheral direction of the hole groove wheel 22, circular arc-shaped protruded faces 21c to be coupled with the recessed faces are formed on the pin wheel 21. Even if a rotating force is applied to the dial on the driven side, the recessed faces of the interlocked hole groove wheel are coupled with the protruded faces of the pin wheel and the recessed faces are centered on the rotation center of the pin wheel, thus the rotating force of the dial is not transmitted to the pin wheel. The jolting of the dial on the driven side can be thereby prevented.

Title: Automatic paper feeding unit
Inventor: ISHIKAWA MASAAKI
IPC: B65H3/52
Filed: 1980-12-26
Abstract: PURPOSE: To prevent erroneous paper feeding by providing a paper feeding board with an inclined angle through which a paper drops owing to its own weight, and by positioning the feeding board in such a way that the extension of the board passes through the center of a paper feeding roller, and thereby enlarging the contact area between a bottom part and the paper feeding roller.  
     CONSTITUTION: A paper feeding board 14 is set at an inclined angles β at which each paper starts dropping of itself due to its own weight, and placed in such a way that the extension B of the top surface of the board 14 passes through the center O of a paper feeding roller 11 or a little above of its. Thus, in paper feeding, the bottom part 13a is brought in contact with the paper feeding roller 11 in a large area, and bites into between the roller 11 and a separating roller 12. Since the friction coefficient between paper is made smaller than that of the roller 12, and the friction coefficient of the roller 12 to paper 13a, 13b... is selected to be smaller than that of the roller 11, the upper layered paper is returned by the roller 12 in the reverse direction of the feeding one.

Title: Electrolytic capacitor and manufacture thereof
Inventor: KISHIMOTO YOSHIO
IPC: H01G9/04
Filed: 1989-07-19
Abstract: PURPOSE:To increase an electrostatic capacity, to simplify a manufacturing process and to improve a lifetime performance by forming an oxide dielectric layer, an electrolytic conductor and an opposite electrode sequentially on the surface of a metal thread electrode. CONSTITUTION:An oxide dielectric layer 2 is provided on the surface of a metal thread electrode 1, an electrolytic conductor 3 is filled up around this oxide dielectric layer 2, and further an opposite electrode 4 is formed on the outer peripheries of them. For the metal thread 1, an aluminum wire having a roughened surface is most suitable, and it can be used in the form of a bundled or porous wire. For the electrolytic conductor 3, a conductive macromolecular composition is used mainly. When the opposite electrode 4 shaped in a cylinder is disposed around the metal thread electrode 1 as a core, a dopant concentration becomes high in the vicinity of the metal electrode 1 and, therefore, stability with time as well as conductivity is improved. Since the metal thread for which manufacturing processes can be combined successively is used as the electrode, the electrolytic capacitor is formed in such a shape as a wire around the thread as the core and then cut, and thereby a capacitor shaped in a chip can be manufactured with ease.

Title: Cage valve
Inventor: SUZUKI HIROFUMI
IPC: F16K3/24
Filed: 1980-12-26
Abstract: PURPOSE: To enable free adjustment of flow condition by rotatably fitting a cylindrical stopper with an eccentric hole in a circular hole made near the full stoppage line of a cage.  
     CONSTITUTION: Flow rate of a fluid, which goes to a fluid passage 9 from a fluid passage 8 via a window 10, is adjusted by a screen area of the window 10 made by a plug 6 which moves up and down. A descrepancy from ideal property is sometimes generated where valve opening is small, due to work tolerance of the plug 6 and the inside diameter of a cage 7. Therefore, when a cylindrical stopper 12 is rotated, its through hole 12b is lowered from the maximum degree to 60°, 120° and 180° according to rotational angle. As the result, flow characteristic at a low relative travel part can be freely adjusted by selecting rotational angle.

Filed: 1987-07-29
Abstract: PURPOSE:To obtain low-cost discharge plasma, and to treat the surface with excellent reproducibility by installing a superconducting magnetic field coil giving a constant magnetic field into space near a sample base and a sample outside a sample chamber. CONSTITUTION:A superconducting magnetic field coil 21 giving a constant magnetic field into space near a sample base 8 and a sample 7 is mounted outside a sample chamber 9. The magnetic field near the sample base 8 and the sample 7 near the inside of the coil 23 maintains the intensity of the magnetic field by the coil 21 applied first because the coil 21 cancels the effect section of a normal conducting magnetic field coil 1. Consequently, even when the kinds of a gas 6 for plasma, a material gas 10, etc., are changed, the intensity of the magnetic field near the sample 7 is kept constant at all times even when currents by the coil 1 are altered for stabilizing the state of discharge. Accordingly, low-cost discharge plasma is acquired, and the surface is treated with excellent reproducibility.
