    • An apparatus which is capable of providing an advance warning for indicating excessive discharge of a battery, during the supply of electric power from the battery to a load, prior to the battery being unuseable for powering the load. The apparatus comprises first power supplying means for initially supplying power from the battery to the load, supervisory control means for continuously monitoring the residual or current power capacity of the battery and interrupting or reducing the supply of power to the load when a predetermined quantity of power consumption is detected, and second power supplying means for supplying, subsequently, the residual power of the battery to the load when the first power supplying means is rendered inoperative.

    • The charging apparatus for charging a secondary battery by controlling the charging current on the basis of the change with time of the voltage of the secondary battery through sampling of the voltage. The voltage of the secondary battery is sampled by use of a voltage/frequency converter which converts the voltage of the secondary battery to pulses of a frequency corresponding to the voltage and a counter which counts the converted pulses for a predetermined time with a predetermined cycle. The counting time of the counter is set to be larger than half a cycle of a commercial alternating current source used as a charging power source. Short duration fluctuations in the battery voltage due to charging power source variations are compensated for because the average voltage during this time is converted to digital values, thus making it possible to sample the voltage of the secondary battery correctly without being influenced by the change of the voltage of the power source.
    • 根据二次电池的电压随时间的变化,通过对该电压的取样来控制充电电流来对二次电池进行充电的充电装置。 通过使用电压/频率转换器对二次电池的电压进行采样,该电压/频率转换器将二次电池的电压转换为与电压对应的频率的脉冲,并且以预定周期将转换的脉冲计数预定时间的计数器。 计数器的计数时间设定为大于用作充电电源的商用交流电源的半周期。 由于充电电源变化导致的电池电压短暂的波动被补偿,因为在此期间的平均电压被转换为数字值,因此可以正确地对二次电池的电压进行采样,而不会受到 电源电压。

    • An electric shaver is described which comprises: a housing; a fixed cutter mounted to the housing; and a movable cutter arranged to slide along the fixed cutter. A driving motor is linked to the movable cutter for slidably moving the movable cutter along the fixed cutter. A power supply circuit is electrically connected to the driving motor for supplying a selectively controllable voltage to the driving motor. The power supply circuit comprises a charging circuit and a control circuit. The charging circuit includes a voltage reducing transformer, and a rectifying element and a rechargeable battery connected in series with the secondary coil of the voltage reducing transformer. The control circuit is connected to the driving motor in parallel to the rechargeable battery. The control circuit includes a starting switch and at least one voltage drop element having a substantially constant voltage characteristic. The starting switch and the voltage drop element are connected in series with the driving motor. The control circuit further includes means for selectively providing a short circuit providing means is connected in parallel to the voltage drop element and in parallel to the voltage drop element and includes an operator controllable switch mounted to the housing for selectively shorting the voltage drop element.
