  • Patent number: 9030070
    Abstract: A method and device for orienting a timepiece component on both ends of which two magnetic/electrostatic fields each attract it onto a pole piece, with an unbalance in the intensity of the fields around the component, in order to create a differential in the forces thereon and to press one of the ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic/electrostatic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each attracted by a magnetic/electrostatic field transmitted by one of the ends, or generating a magnetic/electrostatic field attracting one of the ends, the magnetic/electrostatic forces exerted on the two ends are of different intensity, in order to attract only one end into contact with only one of the pole piece surfaces.

    Abstract: The present invention relates to a buffer member, a shock buffering structure of an electronic device, and an electronic device. A buffer member interposed between a wristwatch case and a watch module therein is composed of a viscoelastic body which, when the wristwatch case receives shock, reduces shock to be transmitted to the watch module by changing its shape while converting the kinetic energy to heat energy, and quickly reduces elastic force on the watch module by reducing the conversion of the kinetic energy to elastic energy accompanying the shape change. The viscoelastic body includes a first viscoelastic body section formed to cover the top and side surfaces of the module, a second viscoelastic body section arranged in predetermined portions of the first viscoelastic body section, and a third viscoelastic body section arranged along the inner peripheral edge of the top surface of the first viscoelastic body section.

  • Patent number: 4308606
    Abstract: A rotary pendulum without time-keeping function, comprising an inertial body suspended from a clockwork housing of a preferably electronically driven timepiece through the intermediary of an elongate torsion spring, is periodically accelerated by the impact between a vane on the spring and radial camming teeth of an impeller wheel frictionally entrained on a horizontal seconds shaft of the timepiece via a spiral spring anchored to that shaft. The vane, near the upper end of the torsion spring, oscillates only through a half-cycle limited on the return swing by an abutment on the clockwork housing. The inertial body is secured to a latch member at the lower end of the torsion with the aid of a coupling ring on which a drag ring is rotatably mounted, the latter carrying a radial fin engageable with a fixed stop pin as well as with a peripheral lug on the coupling ring whereby the body can turn through almost two full revolutions before being positively arrested.
