Abstract: Provided is a crane which can suppress deformation and vibration of a crane structure in travel and stop of the crane. Inverters are installed respectively in travel devices which are arranged on the opposite sides with a gap in a transverse direction. Each of the inverters independently measures a torque generated in a motors to which the inverter is connected and reduces the rotation speed in the command from a controller to the motor such that the greater the measured torque is, the greater a ratio of reduction is.

Abstract: One three-phase transformer (71A) out of two paired three-phase transformers among three-phase transformers provided for respective feeder lines outputs, as operating power, first three-phase AC power of the same voltage phase as that of power-supply power. The other three-phase transformer (71B) out of the two paired three-phase transformers outputs, as the operating power, second three-phase AC power of a voltage phase shifted by ?/6 from that of the power-supply power. The power storage device (4) of a crane apparatus (10) stores DC power supplied from a three-phase full-wave rectifier (1) to a common bus (B), and supplies the stored power to the common bus (B) upon reduction of the DC power.

Abstract: A three-phase full-wave rectifier (21) performs full-wave rectification of three-phase AC power (11A) supplied from ground power supply equipment, and supplies obtained DC power (12A) to a common bus (B). A ?-Y connection type three-phase transformer (2) outputs three-phase AC power (11B) of a voltage phase shifted by ?/6 from the three-phase AC power (11A). A three-phase full-wave rectifier (22) performs full-wave rectification of the three-phase AC power (11B) output from the three-phase transformer (2), and supplies obtained DC power (12B) to the common bus (B).

Abstract: This invention relates to a color image recording apparatus, which once records an image on an intermediate sheet by means of a recording means, and then transcribe the recorded image on any desired recording sheet. Where, in the step of recording on the dye depositing layer of intermediate sheet, the color image is recorded for a length longer than that the sheet holding body can hold the intermediate sheet at one time by repeating the process cycle of multi color-recording with the intermediate sheet held sticking fast on the sheet holding body and releasing of the intermediate sheet from the tight holding; and then the dye depositing layer carrying the recorded image is transcribed on any desired recording sheet.In doing this way, snaking motion and slipping of the intermediate sheet are prevented, heat shrinkage of the intermediate sheet is curtailed to produce a quality color image having precise alignment of color positioning on any desired recording sheet.
