    • The impurity density of a photoelectric transducer n-layer (7) and the impurity density of a p-layer ( 6 ) of an impurity region in which the electric transducer (7) and a transfer channel (9) are formed, are each distributed to have its maximum value in a more interior part from the surface of a semiconductor substrate (5). Alternatively, i) a thin, high-density p-layer (34) and ii) a thick, low-density p-layer (33) of an impurity region in which the electric transducer (7) and the transfer channel (9 ) are formed may be formed. Each minimum potential in these two p-layers (33, 34) is made to have a different dependence on the voltage applied to an n-type semiconductor substrate ( 5). The thick, low-density p-layer ( 33 ) is formed in such a way that it comes into contact with part of the photoelectric transducer n-layer (7) at its bottom portion. The above constitution can bring about a solid-state image pickup device that can prevent the blooming phenomenon, causes less residual images, and can operate as an electronic shutter with ease.

    • A DC power supply apparatus includes a rectifier circuit for rectifying an input AC voltage to develop a rectified voltage between two output terminals thereof. First and second smoothing capacitors are connected in series between the output terminals of the rectifier circuit. First and second voltages developed across the first and second capacitors are applied to first and second inverters which convert the applied voltages to high-frequency voltages, which, in turn, are applied to a transformer. The transformer develops a transformed high-frequency voltage which is converted to a DC voltage by a converter. A voltage detector detects the first and second voltages, and the detected first and second voltages are compared in a microprocessor. An inverter control circuit controls the first and second inverters in accordance with the result of comparison, in a sense to make the voltages across the first and second smoothing capacitors equal.

    • An arc welder includes an inverter for converting a DC voltage to a RF voltage which, then, is rectified by a rectifier. The output of the rectifier is smoothed by a DC reactor. A RF generator provides RF current to flow between a workpiece and a main electrode of the welder forming a welder load, which initiates arcing between the workpiece and the main electrode. Initiation of arcing causes output current from the DC reactor to be supplied to the welder load, so that steady-state arcing is established. The DC reactor has a relatively small inductance which permit the output current from the DC reactor to reach a value required for establishing the steady-state arcing within a time period during which the RF generator provides RF current. The RF voltage from the inverter has a relatively high frequency so that the output current from the DC reactor can sustain the steady-state arcing.
    • 电弧焊机包括用于将DC电压转换成RF电压的逆变器,然后由整流器整流。 整流器的输出由直流电抗器平滑。 RF发生器提供RF电流以在焊接工件的工件和主电极之间流动,形成焊接负载,其启动工件和主电极之间的电弧。 引起电弧会使直流电抗器的输出电流提供给焊机负载,从而建立稳态电弧。 DC电抗器具有相对小的电感,其允许来自DC电抗器的输出电流达到在RF发生器提供RF电流的时间段内建立稳态电弧所需的值。 来自逆变器的RF电压具有相对高的频率,使得来自DC电抗器的输出电流可以维持稳态电弧。
