  • Patent number: 9748874
    Abstract: A motor control device includes DC voltage circuitry which obtains a DC voltage, an inverter which converts the DC voltage obtained by the DC voltage circuitry into an AC voltage that is output to a motor, a voltage detector which detects the DC voltage obtained by the DC voltage circuitry, and regenerative controller circuitry which controls actuation of the regenerative circuit based on the DC voltage detected by the voltage detector. The regenerative controller circuitry waits until a predetermined waiting time period has elapsed and thereafter actuates a regenerative circuit in the DC voltage circuitry, independently of actuation control by second regenerative controller circuitry in a second motor control device that also obtains the DC voltage, after the voltage detector detects that the DC voltage exceeds a predetermined threshold voltage.

  • Publication number: 20160369427
    Abstract: The present invention is: a horizontal heat treatment apparatus for continuously heat-treating by moving a continuous flat workpiece to be treated (carbon-fiber-precursor fiber bundles) back and forth in the horizontal direction on multiple levels inside a heat treatment chamber, the horizontal heat treatment apparatus being characterized by being provided with a sealing chamber (4) which is continuous from the entrance (6) side of the heat treatment chamber (2) in to which the workpiece to be treated is conveyed to the exit (6?) side thereof and that is vertically delimited by partition plates making a heat transfer zone in which 2 to 4 levels of the workpiece are transferred, among which the temperature of the workpiece transferred in a lower level is higher than the temperature of the workpiece transferred in a higher level. As a result, the horizontal heat treatment apparatus completely prevents leakage of poisonous gas produced in the heat treatment chamber, and effectively prevents energy loss.
