  • Publication number: 20150357725
    Abstract: A terminal includes a connector portion electrically connectable to an external terminal, a tubular crimp portion formed integrally or separate from the connector portion and crimps with a wire, and a transition portion coupling the two. The tubular crimp portion of a copper or copper alloy metal base material or a metal member having the same is a tubular member closed on transition portion side and reduces in diameter towards the transition portion side such that a conductor-end portion of the electric wire is un-exposed. The tubular crimp portion has a belt-shaped weld portion along a longitudinal direction of the tubular crimp portion. A circumferential direction of the tubular crimp portion matches the RD-direction of the base material. A sum of area ratios R1, R2 and R3 in a rolling plane of the base material, of Cube-, RDW-, and Goss-oriented crystal grains, respectively, is greater than or equal to 15%.

  • Publication number: 20150333416
    Abstract: A barrel portion which allows the pressure-bonding connection of an aluminum core wire exposed on a distal end of an insulated wire covered with an insulating cover is formed into a cylindrical shape by bending barrel portion corresponding portions of a terminal base material in a terminal developed state about a terminal axis. In abutting end portions where the barrel portion corresponding portions abut each other, a welded part which welds the end portions is formed along a long length direction of the insulated wire. The welded part is formed on an upper surface concave portion and a projecting portion where an amount of plastic deformation of a conductor pressure-bonding section generated along with the pressure-bonding of the conductor pressure-bonding section becomes larger compared to other portions in a circumferential direction of the conductor pressure-bonding section.

  • Patent number: 4622636
    Abstract: A system and method for automatically controlling the speed of an automotive vehicle holds the vehicle speed constantly at a set vehicle speed when there are no other vehicles in front of the vehicle and controls the vehicle speed so as to follow another vehicle moving in front of the vehicle according to the distance between the two vehicles. The system disables both of the above-described functions when the vehicle speed is outside of a predetermined speed range around a set vehicle speed after the leading vehicle is no longer in front of the vehicle or a predetermined interval of time after the other vehicle has disappeared from a front detection area.
