摘要： PURPOSE:To obtain a cord for an earphone hard to bent by external forces and having good elasticity by laying a linear or coil-shaped super elastic alloy wire made of Ni-Ti group alloy along a conductive wire and covering them with a insulating layer. CONSTITUTION:A Ni-Ti group alloy is formed into a linear shape by repeating annealing and cold-working after casting and hot-working and then formed into a linear super elastic alloy wire 5 by means of application of a predetermined heat treatment. Then the alloy wire 5 is laid along the outside of a conductive wire 4 and covered with an insulating layer 6 of a soft vinyl chloride to manufacture a cord. The Ni-Ti group alloy is formed in the construction of a cubic crystal in the basic phase condition of a high temperature phase and it is cooled to the martensite transformation temperature to turn in the martensite phase of a single rhombic crystal construction. The alloy is heated again, thereby, it is reversely transformed through the reverse transformation temperature to is exhibited return to the basic phase and thus a shape memory effect. An earphone cord hard to bent by an external force and having good elasticity can be obtained by incorporating this super elastic alloy wire in a cord.

摘要： PURPOSE:To reduce the number of working processes of connecting a fastener and the manufacturing cost of the fastener by forming the cross-section of the fastener made of a shape- memory alloy in a horseshoe shape, and at the same time forming the fastener so as to exhibit such bi-directivity that a slit is opened wider at a low temperature while being closed at room temperature so as to generate engaging force. CONSTITUTION:A fastener 2 made of a shape-memory alloy, formed with a slit 1, is formed at its cross-section in a horseshoe shape, and at the same time it is formed with such bi- directivity that the slit 1 is opened wider at a low temperature while being closed to generate engaging force when the fastener is heated to room temperature. Or the fastener 2 made of the shape-memory alloy, formed in the forseshoe shape, is kept in a constant-temperature bath 3 controlled at a temperature of not more than (Ms point +50 deg.C), and then a jig 4 whose head is wedge-shaped is inserted into the R portion of the fastener, so that the slit 1 is opened wider than an opening of a size equivalent to the inside diameter of the R portion. Thereafter, when the jig 4 is pulled out from the R portion and the fastener is heated to room temperature the fastener exhibits such bi-directivity that the slit 1 is closed while being opened wider when the fastener is cooled to its low temperature. This can reduce the number of working processes of connecting the fastener to a liquid-crystal display panel so as to reduce the manufacturing cost of the fastener.

摘要： PURPOSE:To substantially strengthen a restricting force, improve reliability and save a shape memory effect alloy of a joint by providing projections on the inner periphery of a liner so that the distance between the diametrical ends of the projections is made equal or smaller than the inner diameter of the liner. CONSTITUTION:A liner 3 is provided on the inner periphery circumferentially with projections so that the distance between the diametrical ends of the projections is equal to or smaller than the inner diameter (d) of the liner by recessing the projection part. Thus, a piping can be connectively inserted and set rapidly without damaging the projections. While the liner 3 is formed on the outer diameter (D) with a protrusion (D')corresponding to the inner diameter (d) in molding the liner 3, a joint can be connectively inserted only on this part in execution so that the use of a long joint is not needed and thereby an amount of a shape memory effect alloy can be substantially saved.

摘要： PURPOSE:To make a joint strong against torsion in the circumferential direction of a pipeline in a shape memory alloy joint, in which a shape memory alloy joint and a cylindrical liner are arranged, by providing projections inside of the inner surface of the liner, and providing projections having notch parts in the inner surface of the liner. CONSTITUTION:Projections 4 are provided in the inner surface of a liner 3 located inside of a shape memory alloy joint along the circumferential direction of the liner to improve sealing property of the connection with a pipeline, and while projections 4' having partial notch parts 5 are provided along the circumferential direction of both ends outside of the projections 4. These projections 4' can be provided so that the notch parts 5 are distributed evenly in the circumferential direction, or so that the notch parts 5 are distributed unevenly, or multiple projections 4' can be provided in both ends so that the notch parts 5 are distributed evenly in the circumferential direction. A Ni-Ti group alloy, Cu-Zn-Al group alloy and other ordinary shape memory alloys can be used as the shape memory alloy for a joint. As a result, the joint is strong against the force in the twisting direction to improve reliability as a pipeline system.
