  • Publication number: 20140145453
    Abstract: The instant disclosure provides a push latch having a pivotally mounted blocking hammer including a head with a lever arm extending away from the head to a counter-weight. Under normal operating conditions, the hammer is held in an inert/balanced condition. Under such normal conditions, a portion of the hammer head may be in periodic contact with a resin of tacky character defining a bumper to aid in dampening vibration. Upon the occurrence of a high impact force, the rotational force provided by the counterweight is sufficient to cause the hammer to rotate into blocking relation relative to the latching mechanism so as to prevent unlatching. In the rotated condition, the counterweight may be in contact with an optional resin of tacky character defining a bumper to reduce rebound action.

  • Publication number: 20140004684
    Abstract: The present invention provides a method for preparing a GOI chip structure, where, in the method, first, a SiGe on insulator (SGOI) chip structure is made by using a Smart-Cut technology, and then, germanium condensation technology is performed on the SGOI chip structure, so as to obtain a GOI chip structure. Because the SGOI made by the Smart-Cut technology basically has no misfit dislocation in an SGOI/BOX interface, the threading dislocation density of the GOI is finally reduced. A technique of the present invention is simple, the high-quality GOI chip structure can be implemented, and the germanium condensation technology is greatly improved. An ion implantation technology and an annealing technology are quite mature techniques in the current semiconductor industry, so that such a preparation method greatly improves the possibility of wide use of the germanium concentration technology in the semiconductor industry.
