  • Publication number: 20240128917
    Abstract: A motor drive device includes: an inverter circuit configured to drive a motor; a drive circuit to which a control voltage is applied, the drive circuit being configured to output a drive signal to the inverter circuit; and a relay configured to stop application of the control voltage to the drive circuit. The relay is configured to detect a motor current that is output from the inverter circuit to the motor, and to stop application of the control voltage to the drive circuit when the motor current reaches a first threshold or higher that is determined in advance.

  • Patent number: 11501729
    Abstract: A source driver includes a data latch unit that outputs acquired pixel data, a gradation voltage conversion unit that acquires the pixel data outputted from the data latch unit and converts the pixel data to gradation voltages, an output unit that amplifies and outputs the gradation voltages to source lines, and a timing control unit that controls the timing of the output of the pixel data from the data latch unit. The timing control unit performs control such that the longer a source line is from a source driver to a pixel column, the smaller the timing difference is between acquisition of the pixel data by the data latch unit and the output of the pixel data.

  • Patent number: 10861675
    Abstract: A controller disclosed herein drives, in a first step, a high frequency generating source at a first energy condition, and drives, in a second step, a high frequency generating source at a second energy condition. Prior to a switching time of the first step and the second step, the controller switches gas species supplied from the gas supply system into the processing container, and sets a gas flow rate in an initial period just after the switching to be larger than a gas flow rate in a stabilization period after lapse of the initial period.

  • Patent number: 10669125
    Abstract: An elevator rope guide system comprises a plurality of rope guides for restricting the swaying of at least one main rope and a plurality of stop mechanisms each configured to stop a corresponding rope guide. The rope guides are located above an elevator car and/or counterweight and are vertically movable along a hoistway. The stop mechanisms are positioned at different intermediate heights along the hoistway. The elevator rope guides are collected by the elevator car or counterweight as the elevator car or counterweight moves up and are stopped by a corresponding stop mechanism as the elevator car or counterweight moves down.
