Title: Method for preventing hot working crack in tough pitch copper ingot
Inventor: WATABE MASAHITO
IPC: C22B9/02
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To solve the problems that, as for dry refining using molten copper oxidtion, Pb is hard to remove in oxidation refining for molten copper viewed from the thermodynamic characteristics of Cu2 O slag and the distribution equilibrium value of impurity elements in the molten copper and the removal of hot working cracks and inside cracks in a tough pitch copper ingot is hard. SOLUTION: This hot working method for a tough pitch copper ingot is the one in which a tough pitch copper ingot contg. Pb with inevitable impurities other than Pb is subjected to hot working to produce a product. In this case, the grain size 2 is controlled so as to regulate the Pb content (= apparent boundary Pb concn. Cpb ) to <=3.5×10<8> (g/mm<2> ). Then, the crystal grains are refined by the control of the grain size 2, so that Pb is dispersed into the tough pitch copper ingot 1, the content of Pb per unit grain boundary area is made small, and the generation of hot working cracks at the time of the hot working can be prevented.

Title: Controller for electric automobile
Inventor: YOKOI YASUO
IPC: B60L7/12
Filed: 1991-05-17
Abstract: PURPOSE:To regenerate kinetic energy at the time of braking and potential energy at the time of traveling on a downhill efficiently, in the form of electric energy, to a battery. CONSTITUTION:A booster type chopper comprising a high frequency reactor L, a switching element Q2 to be turned ON/OFF through a brake mechanism and a rectifier D2 for feeding the electromotive force of the motor to the battery upon turn OFF of the element Q2 is connected between the DC motor and the battery Ba. When the motor is decelerated, a current induced by the electromotive force of the motor flows through the reactor and the element Q2 being turned ON and that current is commutated to the rectifier upon turn OFF of the element Q2 to be recovered efficiently back to the battery through the reactor L. In case of downhill traveling, the electromotive force is higher than the battery voltage and thereby a current flows from the motor through the reactor and the rectifier into the battery to be recovered therein.

Title: Surface mounting substrate
Inventor: YAMAGUCHI KENJI
IPC: H05K3/38
Filed: 1989-05-02
Abstract: PURPOSE:To improve a surface mounting substrate in heat resistant and adhesive property by a method wherein a treated layer of Zn or Ag is provided through an electroplating method onto the surface of the copper layer of a three-layered clad material composed of copper/Fe-Ni alloy/copper onto which an insulating layer is bonded. CONSTITUTION:The main body of a surface mounting substrate 1 is formed of a clad material of three-layered structure that an Fe-Ni alloy layer 3 is interposed between copper layers 2 and 4, and when an insulating layer such as an epoxy resin layer or the like is bonded onto one side or both the sides of the clad material, a treated layer 5 of Zn or Ag is formed on the surface of the copper layer 2 on which the insulating layer is bonded. The reason that a dissimilar metal layer laminated on a copper layer is formed of Zn or Ag is that a Zn or an Ag layer serves as a catalyst better than an Ni layer to protect a resin layer against deterioration by oxidation. A Zn or an Ag treated layer is formed through a usual electroplating method.
