    • A booster circuit has: a charge pump configured to perform a booster operation that boosts a voltage supplied from an external power source and outputs the boosted voltage as an output voltage through an output capacitor; and a feedback circuit section configured to control the booster operation depending on the output voltage. A mode of the booster operation includes: a charge mode that charges the output capacitor with the voltage supplied from the external power source; and a discharge mode that discharges the output capacitor. The mode of the booster operation is switched between the charge mode and the discharge mode depending on the output voltage. The feedback circuit section has a booster operation control section that secures a period during which the mode is not switched between the charge mode and the discharge mode in accordance with an external synchronizing signal.
    • 升压电路具有:电荷泵,被配置为执行升压操作,升压从外部电源供给的电压,并通过输出电容器输出升压电压作为输出电压; 以及反馈电路部,被配置为根据输出电压来控制升压操作。 升压器操作的模式包括:充电模式,其利用从外部电源供应的电压对输出电容器充电; 以及对输出电容器进行放电的放电模式。 根据输出电压,升压操作的模式在充电模式和放电模式之间切换。 反馈电路部分具有升压器操作控制部分,其根据外部同步信号确保在充电模式和放电模式之间不切换模式的期间。

    • A piping joint that enables welding without back shielding and without oxidized scaling on the pipe's inner surface. A piping joint has an inner fitting portion formed around the circumference of an end of a first tubular material, and a first bevel is formed on the radial outside of the inner fitting portion around the circumference. An outer fitting portion, fitted to the radial outside of the inner fitting portion, is formed on the end of a second tubular material butt welded to the first tubular material, and a second bevel is formed around the circumference at the end of the outer fitting portion facing the first bevel. The cross-section of the face of the inner fitting portion located on the radial outside, and the cross-section of the face of the outer fitting portion located on the radial inside, are completely round with a constant circumferential curvature.
