Abstract: First windings of a first common mode transformer and second windings of a second common mode transformer are connected in series via connection lines. The windings are connected to an AC power supply via connection lines. The first windings are connected to a three-phase motor via connection lines, a converter, and an inverter. High-frequency leakage currents flowing in the connection lines are detected as a common mode voltage by a winding for common mode voltage detection. An output voltage is inputted via a filter to a voltage amplifier unit that amplifies the output voltage, and the amplified voltage is applied to a winding via a capacitor in substantially a same direction as a direction of the common mode voltage. As a result, leakage currents are reduced by induced voltages on the windings.

Abstract: When mispicking occurs, a weft yarn continuous with a mispicked weft yarn is inserted into the shed of warp yarns in a loop by the jetting of a main picking nozzle and auxiliary picking nozzles. A weft yarn retaining member is positioned in the loop of the weft yarn and the mispicked weft yarn is pulled to be removed from the picking side by way of the weft yarn. Given auxiliary picking nozzles stop jetting when the weft yarn is inserted in a loop so that the tip end of the loop of the inserted weft yarn is limited in the extent to which it moves in the picking direction, and thus does not extend substantially beyond the arriving side of the shed of warp yarns, so as to prevent entanglement thereof with various other members.
