  • Watch
    Patent number: 10579019
    Abstract: A watch including: a first drive mechanism including a hand having a rotational axis along a first direction, a wheel train, and a drive power source; and a second drive mechanism including a hand having a rotational axis along a second direction different from the first direction, a wheel train, and a drive power source, wherein the first drive mechanism and the second drive mechanism are mounted separately. Each of the first direction and the second direction is defined along a normal direction to dial at a position of a rotational axis of the hand.
    Type: Grant

  • Method of manufacturing pure niobium plate end-group components for superconducting high frequency accelerator cavity
    Patent number: 10252314
    Abstract: Targeting mass production, the present invention provides an advanced method of manufacturing pure niobium plate end-group components from pure niobium plate material for superconducting high frequency accelerator cavity by means of innovative shear-blanking followed by innovative forging procedures, wherein the invention is to convert the procedure/production method from the conventional machining or waterjet cutting followed by the conventional cold forging to the whole press-forming The invention gives the drastic effects on cost-effectiveness and press-performance.
