Title: Battery switcher for motor vehicle
Inventor: INABA MASAMITSU
IPC: B60L11/18
Filed: 1993-04-16
Abstract: PURPOSE:To allow smooth starting or acceleration of a vehicle by switching the connection of main and auxiliary batteries depending on the value of current flowing through a running motor. CONSTITUTION:A current sensor 7 detects the current flowing through a running motor and when it is lower than a reference level, a running control circuit 2 connects a main battery 1 and an auxiliary battery 5 through a step-down converter 6. Consequently, the voltage of the main battery 1 is stepped down to the voltage V2 of the auxiliary battery 5 and the voltage V2 is fed to the auxiliary battery 5. When the current flowing through the running motor 3 is higher than the reference level, the running control circuit 2 connects the main and auxiliary batteries 1, 5 through a booster converter 8. Consequently, the voltage V2 of the auxiliary battery 5 is boosted up to the voltage V1 of the main battery 1 and the voltage V1 is fed to the running motor 3. This constitution allows smooth starting or acceleration of the vehicle.

Title: Soldering method and basic soldering material
Inventor: ANADA TAKAAKI
IPC: H05K3/34
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent defective joint due to cracking by forming a nickel skin layer on the surface of a basic material principally comprising copper and forming a thin layer of gold, silver, palladium or tin on the surface of the nickel skin layer thereby blocking undue growth of a compound layer under high temperature. SOLUTION: Since a nickel skin layer is formed on the surface of a basic material principally comprising copper, copper is diffused into the nickel skin layer when solder adheres onto the basic material and boded through formation of a compound with zinc in the solder. Consequently, the solder is jointed surely to the basic material. Since wettability of tin-zinc based solder to nickel is insufficient when the nickel skin layer is formed simply on the surface of the basic material of copper, initial strength can not be ensured sufficiently. When a thin layer of gold, silver, palladium or tin is formed on the surface of the nickel skin layer, wettability of solder to the surface of the basic material is improved resulting in good soldering and enhanced initial strength.
