  • SCREW ATTACHMENT, FASTENING ASSEMBLY HAVING SCREW ATTACHMENT, AND PROCESS OF RELEASING FASTENING ASSEMBLY
    Publication number: 20100162550
    Abstract: A screw attachment (10, 10?, 10?) disposed around a fastening piece (17) secured to a main fastening body (25a), the screw attachment sandwiched between a head (17b) of the fastening piece and a securing object (22) so that the screw attachment bears a securing force of the fastening piece to press the securing object. The screw attachment includes a pair of arms (12, 13) made of a shape restoring material. Each arm has a fore end, and the fore ends are joined to each other with an adhesive material that is softened when heated. The arms expands radially such that the screw attachment is released from the head of the fastening piece when heat or force is applied to the arms.

  • Ti-Ni-V shape memory alloy
    Patent number: 4894100
    Abstract: A shape memory alloy consisting, by atomic ratio, of V 0.25-2.0% and the balance of Ni and Ti, an atomic ratio of Ni and Ti being 0.96-1.06. The shape memory alloy has a good workability and a reduced temperature difference between a martensitic transition start point and an austenitic transition finish point. When the atomic ration of Ni/Ti is 0.96-1.02, the martensitic transition start point is the room temperature or higher. When the atomic ratio of Ni/Ti is 1.02-1.06, the martensitic transition start point is the room temperature or lower. The shape memory alloy has a pseudo elasticity.
