  • Chronograph timepiece and lever device for timepiece
    Patent number: 6428201
    Abstract: In a state in which a chronograph mechanism is not operated, a coupling lever 442 positions a second counting transmission pinion 212b such that the second counting transmission pinion 212b is separated from a second chronograph wheel 214. In a state in which the chronograph mechanism is operated, the coupling lever 442 is moved to rotate such that the chronograph mechanism is operated. As a result, the second counting transmission pinion 212b is in mesh with the second counting wheel 214. By bringing an outer peripheral portion 442f of a guide frame 442d into contact with a contact portion 202d of a chronograph bridge 202, movement of the coupling lever 442 is set.

  • Multi-functional timepiece
    Patent number: 5956294
    Abstract: A multi-functional timepiece comprises a base, a wheel train mounted on the base for rotation, a cam member rotationally driven by the wheel train about a rotational center, and a rotary member mounted to undergo angular displacement in opposite directions. A display member is integrally connected to the rotary member for angular displacement therewith to display time or date information. An interconnecting member interconnects the cam member to the rotary member such that rotational motion of the cam member effects angular displacement of the rotary member in the opposite directions.

  • Socket with a plug locking mechanism
    Patent number: 5593313
    Abstract: A socket with a plug locking mechanism has a socket body having an opening formed in a specified position. Plural receptacles for supplying electric power are exposed at their top face from the opening of the socket body and are electrically and mechanically connected with plural terminals projectively formed on the top end of a plug. Plural projecting parts are integrally formed with the same material as the socket body as keeping a specified interval between them on both sides of the opening. Each of the plural projecting parts has at least one hole. A spring has a locking part formed to be engaged with the rear part of the plug in its middle part, and is set in the plural projecting parts so as to be freely turned by inserting each end part thereof into each of the holes which are formed in each of the plural projecting parts.
