Title: D.c. uniterruptible power supply unit and part which serves double purpose of booster and power controller and is used for its unit
Inventor: MORIWAKI HARUROU
IPC: H02J7/34
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To miniaturize and lighten an uninterruptible power supply unit by collectively performing conversion control for a DC output current and the charging current of a storage battery by a part which serves a double purpose of AC/DC conversion and charging, preferentially supplying the output to a DC output terminal and at the same time using the remainder of the output for the charging current of the storage battery through a part which serves a double purpose of a booster and a power controller. SOLUTION: The rated current Ir of a part 2 which serves a double purpose of AC/DC conversion and charging is set at the sum total of a current to be supplied from a DC output terminal 6 and a minimum required charging current. When an AC input from an AC input terminal 1 is interrupted, a switch part 5 is closed to supply electric power to the DC output terminal 6 from a storage battery 4. When the AC input is recovered, the part 2 which serves a double purpose of AC/DC conversion and charging delivers the output current Io from the DC output terminal 6 as a preferential output and delivers the remainder of the output as the charging current of the storage battery through a part 3 which serves a double purpose of a booster and a power controller. Therefore, this uninterruptible power supply unit is miniaturized and lightened, so that it may be constituted at low costs.

Title: Solder material
Inventor: HANIYU KAZUTAKA
IPC: C22C13/00
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To obtain a non-lead solder material capable of obtaining an excellent solderability with an excellent mechanical property and wettability by adding a specified quantity of Ge and Cu to the solder alloy consisting of a specified ratio of Zn, Bi and Sn. SOLUTION: This solder material is composed of, by wt., 0.5-10% Zn, 0.5-8% Bi, 0.005-0.05% Ge, 0.3-3% Cu and the balance Sn. Zn and Bi among these elements act so as to lower the molten temperature of the solder material in the range of the above composition ratio. Ge and Cu are added in order to improve the wettability of the solder material. When the composition ratio of Ge and Cu deviates from the above range, the wettability is lowered and the excellent solderability is not obtained. Especially, Cu acts so as to help that Ge is brought in the solder alloy, and a sufficient quantity of Ge is not allowed to contain in the solder when Cu does not coexist.
