    摘要: A double-side image forming apparatus forms an image on one side of a sheet in a laser printer section, reverses the leading edge and the trailing edge of the sheet with respect to the transporting direction in a turnaround section, turns over the sheet by moving the sheet through an upper or lower reversing transport path, and transports the sheet to the laser printer section again. A sheet guiding device guides the sheet output from the turnaround section to one of the upper and lower reversing transport paths. When the sheet is again transported to the laser printer section, an image is formed on the other side of the sheets. This configuration simplifies the structure of the apparatus and reduces the size thereof compared to a configuration in which only one reversing transport path capable of holding the same number of sheets therein is formed.

    摘要: A power conversion apparatus includes serially connected arms U and X, serially connected arms V and Y, serially connected arms W and Z, and a capacitor, the pairs of serially connected arms and the capacitor all connected in parallel to one another. The input-side arms U and X and the output-side arms W and Z are subjected to PWM control so that the arms W and Z are controlled to have a voltage that is lower than that of the arms U and X, thereby providing a step down operation. A step up operation also can be provided by an opposite relation in which the arms W and Z are controlled to have a voltage that is higher than that of the arms U and X, thereby to expand the range within which the output voltage is controlled with the effect of reducing distortion.

    摘要: In controlling the cooling of a hot-rolled steel sheet after hot rolling, a target value of a transformation rate required for obtaining mechanical properties ultimately expected from the hot-rolled steel plate is previously determined, a rate of gamma to alpha transformed fraction of the hot-rolled steel sheet in a section in which the cooling is controlled is detected by transformed fraction detectors, and an elapsed time from the start of cooling is measured to determine the transformation rate of the steel sheet in a cooling stage, the conditions of cooling being controlled so that the transformation rate can coincide with the target value.
