  • Patent number: 5243277
    Abstract: Disclosed herein is a cross coil having a first coil winding for generating a first magnetic field when an electrical current flows therethrough and a second coil winding for generating a second magnetic field when an electrical current flows therethrough, and the second coil winding being wound so as to cross the first coil winding to each other. The cross coil comprises a mechanism for equalizing the magnitude of each of the first and second magnetic fields generated when identical electrical currents flows through each of the coil windings.The equalizing mechanism comprises the arrangement of the turns of the windings in which the individual turns are alternately wound on top of the turns for the other winding.

  • Patent number: 5138968
    Abstract: A cross coil-shaped indicating instrument includes a cross coil structure in which two coils are wound around a coil bobbin at right angles to each other. The coil structure is electrically charged in correspondence to the amount measured so as to form a composite magnet. A magnet rotor is disposed inside the cross coil structure. The magnet rotor has a center rotary shaft rotatable at a predetermined angle in correspondence to the composite magnetic field. A pointer is fixed to the end of the rotary shaft. In order to press the pointer into an appropriate position with respect to the rotary shaft, a pressure recess is formed in the coil bobbin so that a rod-like fixture can be inserted into the recess, and a stopper projects inside the pressure recess to press against the magnet rotor when the fixture is inserted. The stopper makes the magnet rotor stationary. While the rotary shaft remains stationary, the pointer can be fixed to an predetermined indicating position.

  • Patent number: 5118928
    Abstract: An external pinion type odometer, in which the outer diameter of at least a lower digit wheel, a surface portion of which has numbers stamped, is made smaller than the outer diameter of the lower digit wheel, another surface portion of which slidingly contacts with a wide tooth of the corresponding transfer pinion. The stamped numbers do not contact with the wide teeth of the transfer pinion, thereby excluding the likelihood that the stamped numbers will come to peel off.

  • Patent number: 5095266
    Abstract: An indicating instrument having a cross coil comprising a pair of mutually perpendicular coils wound on a coil bobbin for passing therethrough current changing with changes in the quantity to be measured, a magnet rotor disposed inside the coil bobbin for rotating in the direction of a magnetic field which is the combination of the respective magnetic fields generated by the cross coil, and a pointer for indicating the measured quantity which is mounted on a rotary shaft rotatable together with the magnetic rotor. In order to prevent unneccessary vibration of the rotary shaft, the rotary shaft is acted on by a damping force of a viscous liquid. The viscous liquid is accommodated in a recess formed in the upper surface of the magnet rotor, and the damping action is performed in cooperation with a damping projection projecting downward from a part of the coil bobbin.

  • Patent number: 5093615
    Abstract: A movement for instrument is of thin construction. A rotatably supported shaft extends through a thin magnet and supports the magnet on it. The magnet radiates a magnetic field that varies in magnetic field strength in accordance with a sine function along a circular path about the shaft. A signal generator provides a first current and a second current. First straight conductors are disposed in a first direction parallel to the surface of the thin magnet, are laid in the magnetic field of the magnet, and are supplied with the first current through them. Second straight conductors are disposed in a second direction parallel to the surface of the magnet and transverse to the first direction. The second conductors are laid in the magnetic field of the magnet and are supplied with the second current through them. Thus, the magnet is angularly positioned in accordance with the magnitudes and directions of said first and second currents, thereby causing the pointer to indicate the angular position of the magnet.

  • Patent number: 5062135
    Abstract: An indicating gauge for automobiles for displaying the amount of a measurement on a gauge board by a movement. The movement comprises a pair of coils for generating a combined magnetic field in response to a predetermined measurement amount, a magnet rotor having a rotation shaft rotating dependent on the generated magnetic field, a counter shaft rotatably disposed in parallel to the rotating shaft, a pointer mounted on the tip of the counter shaft, a rotation gear secured to the rotation shaft and a counter gear secured to the counter shaft. To fix the pointer to 0 position of the gauge board, a stopper is provided in the counter gear. This obviates the another stopper on the gauge board. The number of parts is reduced, and assembling the gauge can be done easily.
