Abstract: A battery charger charges a discharged battery and can be connected directly to an appliance where it serves as an AC adapter. The output of the battery charger automatically reduces to a trickle maintenance charge as the battery approaches a full charge condition. A Zener diode, used for overcurrent protection automatically turns off the charging function in the event of an overcurrent condition. The circuit automatically resets when the overcurrent condition is removed. A hinged section, when opened out, provides mounting for a battery to be charged. When the hinged section is closed, switches are operated, and electrical connections are made to permit affixing the charger, as an AC adapter, to the normal battery retainer of the appliance.

Abstract: A battery charging apparatus, which charges a secondary battery such as an Ni-Cd battery being used for a battery-driven equipment such as a VTR camera, is provided with a first loading unit for only charging a loaded battery and a second loading unit for charging a loaded battery, for discharging the charged battery, for measuring the capacity of the discharged battery, and for displaying the measured capacity by four steps of its percentage, and which is capable of using either of the both loading units according to the qualities of the battery characteristics of the battery. In this battery charging apparatus, a new battery or a battery with good battery characteristics substantially similar to the new one are charged in the first loading unit and an old battery or a battery with inferior battery characteristics are charged in the second loading unit.

Abstract: A glass fiber reinforced resin composition suitable as an injection molding material for automobile instrument panels. Essentially the resin composition is a blend of 55-77 wt % of a propylene-ethylene block copolymer at least partially modified by graft copolymerization with an unsaturated carboxylic acid or its derivative, 5-15 wt % of an ethylene-propylene rubber in which the content of ethylene is 60-85 wt % and 18-30 wt % of glass fiber having a filament diameter of 8-15 .mu.m. The melt flow index of the modified propylene-ethylene block copolymer and the Mooney viscosity of the ethylene-propylene rubber are strictly specified. The resin composition is pelletized from a melted state such that the glass fiber dispersed in the pellets is not smaller than 550 .mu.m and, preferably, not greater than 1100 .mu.m in mean filament length. This resin composition is good in moldability and provides instrument panels high in rigidity, in heat distortion resistance and also in impact resistance.
