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.

Abstract: A power converting apparatus includes a main inverter having a high-voltage DC power supply that operates at a low frequency employing SiC MOSFETs having a high withstand voltage exceeding 600 V and a sub-inverter having a low-voltage capacitor that operates through high-frequency PWM employing Si MOSFETs having a low withstand voltage. With AC sides of the main inverter and the sub-inverter connected in series, the power converting apparatus outputs AC power having a prescribed voltage waveform by adding voltages individually generated by the main inverter and the sub-inverter. Specifically, the SiC MOSFETs are used only in the main inverter of which devices are required to have a high withstand voltage and the Si MOSFETs are used in the sub-inverter of which devices may have a relatively low withstand voltage, whereby conduction loss is reduced with an inexpensive circuit configuration.
