    • A surface micromachining process for a resin mold including a layer of a resin as a material of the resin mold, which layer has a product's surface forming plane, and a back surface reinforcing member for reinforcing the resin layer. The product's surface forming plane is micromachined by means of at least two masking/blasting treatments. The treatments comprise a primary blasting step of sticking a first mask sheet having a specific window on the product's surface forming plane and blasting blast particles to the product's surface forming plane via the first mask sheet, and a secondary blasting step of peeling the first mask sheet, sticking a second mask sheet different from the first mask sheet on the product's surface forming plane, and blasting blast particles to the product's surface forming plane via the second mask sheet.

    • To adapt to the relative small sizes of portable electronic devices, two battery output terminals of rechargeable batteries are frequently deployed in a close vicinity to each other. Consequently, rechargeable batteries are prone to cause output terminals short. To prevent such output terminals from shorting, a switching circuit and an activating signal generating circuit are deployed between a rechargeable battery and a pair of voltage output terminals. In response to an activating signal generated by the activating signal generating circuit, the switching circuit connects the rechargeable battery to the voltage output terminals. In absence of an activating signal, the switching circuit disconnects the rechargeable battery from the voltage output terminals, so that a short of the output terminals will not occur to the rechargeable battery even if the voltage output terminals are directly connected with each other.
    • 为了适应便携式电子设备的相对小尺寸,可再充电电池的两个电池输出端子经常部署在彼此附近。 因此,可充电电池容易导致输出端子短路。 为了防止这种输出端子短路,开关电路和激活信号发生电路部署在可再充电电池和一对电压输出端子之间。 响应于由激活信号发生电路产生的激活信号,开关电路将可充电电池连接到电压输出端子。 在没有激活信号的情况下,开关电路将可再充电电池与电压输出端子断开,即使电压输出端子彼此直接连接,也不会发生短路的可充电电池的输出端子。
