  • Patent number: 10770316
    Abstract: A substrate processing apparatus includes a substrate holding unit 31 configured to hold a substrate W; an outer nozzle 45 configured to discharge a processing liquid toward a surface of the substrate from a position at an outside of an outer edge of the substrate held by the substrate holding unit such that at least a central portion of the surface of the substrate is covered with a liquid film of the discharged processing liquid; and an actuator 46 (90) configured to change a height position or a discharge angle of the outer nozzle.

  • Patent number: 10693390
    Abstract: In inverter control for supplying power to a motor, a power conversion device includes a temperature sensor for detecting a temperature of the inverter, a voltage sensor for detecting a voltage between terminals of a capacitor that smooths the voltage between terminals between the power source and the inverter, an inverter controller for controlling the inverter, a rotation speed sensor for detecting a rotation speed of the motor, an electric current sensor for detecting electric current supplied to the motor and a discharge determination instruction controller for giving an instruction for discharging electric charges accumulated in the capacitor, in which, control of reducing the rotation speed of the motor and discharge control of the capacitor are performed in accordance with the temperature of the inverter, the rotation speed of the motor and the electric current supplied to the motor.

  • Publication number: 20190168613
    Abstract: A power conversion device includes a backup power source as a power source for a discharge controller that discharges electric charges of a capacitor, and an abnormal state in the backup power source or loads is not capable of being dealt with when power is supplied to loads from the backup power source, which makes an output voltage of the backup power source be in an abnormal state. In order to solve the problem, when an abnormality occurs in the backup power source or in loads and the abnormality is detected in power supply from the backup power source, a place where the abnormality occurs is specified. When the specified place where the abnormality occurs is a load, power supply to the load is stopped, thereby preventing the output voltage of the backup power source from being abnormal even when an abnormality occurs in part of power supply destinations.
