    • A protection method for preventing battery cells from over-discharging and being overcharged, a control circuit, and a battery unit are provided. In the protection method, when a set signal “1” is supplied to a set terminal, a flip-flop outputs “1”. The gate of a discharge control FET then becomes “1”, so that the discharge control FET is OFF regardless of a discharge control signal supplied from a voltage monitor circuit. When a reset signal “1” is supplied to a reset terminal, the flip-flop outputs “0”. The discharge control FET is then switched on and off in accordance with the output of a discharge control circuit of the voltage monitor circuit. In this manner, battery cells connected to an electronic device do not over-discharge, even when they are left unused for a long period of time. Thus, the battery unit can be prevented from deteriorating and shortening the life thereof.
    • 提供一种用于防止电池过度放电和过充电的保护方法,控制电路和电池单元。 在保护方法中,当设定信号“1”被提供给设定端子时,触发器输出“1”。 然后,放电控制FET的栅极变为“1”,使得放电控制FET不管从电压监视电路提供的放电控制信号如何都是OFF的。 当复位信号“1”被提供给复位端时,触发器输出“0”。 然后,根据电压监视电路的放电控制电路的输出,对放电控制FET进行接通和断开。 以这种方式,连接到电子设备的电池单元即使长时间不使用也不会过度放电。 因此,能够防止电池单元劣化,缩短寿命。

    • A sintering compound containing a sinterable powder and a binder removable in a debinding step is injected into a metal mold set provided with a sintering compound injecting mold, in a sintering compound molding step (S104). An add-on forming compound which becomes removable or separable from the sintering compound injection molded body in the debinding step or the sintering step is injected into the metal mold set provided with an add-on mold in an add-on forming step (S102). The sintering compound injection molded body and the add-on are formed integrally with each other in the metal mold set. The integral formation of the add-on and the sintering compound injection molded body enables to prevent damage during release from the mold and make easy to handle the injection molded body.
