  • Patent number: 9616968
    Abstract: A sensing device and a driving module for an electric bicycle having a spindle are provided. The sensing device includes a torque sensor, a slip ring, a grating, and a cadence sensor. The driving module includes a motor, a reducer and the sensing device. The present disclosure combines the slip ring with the grating to integrate the cadence sensor and the torque sensor into one sensing device, such that the sizes of the sensing device and the driving module are reduced.

  • Publication number: 20140144377
    Abstract: A substrate and mask attachment clamp device comprising a push assembly, an upper clamp mechanism and a lower clamp mechanism is disclosed. The upper clamp mechanism comprises a first inclined surface, a swing element, a second inclined surface and a sliding surface. The lower clamp mechanism comprises a lower clamp retainer and a clamp movably. During the push assembly moving along a first direction, the push assembly moves with respect to the first inclined surface to drive the upper clamp mechanism to move along a second direction. The push assembly further drives the second inclined surface to move with respect to the swing element, so that the swing element drives the clamp to move along a third direction opposite to the first direction, and drives the sliding surface to move with respect to the lower clamp mechanism to drive the clamp to move along a fourth direction.

  • Patent number: 7927425
    Abstract: A power-delivery mechanism is provided in the present invention, which utilizes an element with airtight and flexible characteristics coupled to a power-generating unit so as to generate a motion in a specific direction. Besides, an apparatus of plasma -enhanced chemical vapor deposition (PECVD) is also provided in the present invention, which comprises the power-delivery mechanism to load/unload a workpiece onto a stage for processing automatically. Meanwhile, the present invention also provides a height-adjusting unit and a position-indicating unit allowing the operator to adjust the distance between an upper electrode and a lower electrode of the PECVD so that the operator is capable of monitoring and adjusting the distance easily between the upper electrode and the lower electrode outside the chamber of the PECVD.

  • Patent number: 6712926
    Abstract: The present invention describes a chemical solution recycling apparatus in a spin etching and cleaning process chamber for manufacturing semiconductor devices. Modification of the exterior dimension and the main structure of the process chamber is not necessary. The recycling apparatus in accordance with the present invention may separate different chemical solutions into different vessels and recycle them thereafter. The recycling apparatus comprises a recycling ring moving up and down to collect the solution and a recycling circular tray for sorting the chemical solutions in different trenches and drains. Therefore, the chemical solutions may be collected by assigned vessels or may be recycled into the process chamber after necessary quality inspections.
