  • Patent number: 6698992
    Abstract: An elastically expandable positioning device for positioning a cover of a unified pod is disclosed, which has a central fastener having one end protruded on the interface plate and an axial input hole opened at another end, and at least one radial distributing hole equally opened at its circular surface; a ring-shaped inflatable body made from an expandable elastic material; a supporting ring encircled around the central bolt and positioned above the distributing hole, for supporting the inflatable body, the supporting ring having at least one radial inflating hole equally positioned corresponding to the radial distributing hole of the central bolt; and an input fluid source connected to the axial input hole of the central bolt, for providing an input fluid.
    Type: Grant

  • Patent number: 6655423
    Abstract: A front-opening unified pod quick-opening apparatus. The apparatus is positioned in a front-opening unified pod loading system. The apparatus has a rail, a slide, a short linking rod having a first end rotatably fixed on the slide to drive the slide to move along the rail, a long rocker arm having a first end rotatably fixed on a second end of the short linking rod, and a second end rotatably fixed on a pin on the backboard; and a power source. When the power source drives the long rocker arm to rotate upwards around the pin on the backboard, the long rocker arm leads the short linking rod, and the short linking rod drives the slide to move upwards along the rail which results in an upward rectilinear motion, and vice versa.
