  • Patent number: 12084328
    Abstract: A mover control method includes decision processing and control processing. The decision processing is the processing of determining whether or not a mover that is carrying an object thereon is going to deviate from a traveling route, through which the mover, as well as the object, is allowed to pass. The control processing (first control processing) is the processing of controlling the mover based on a result of the decision processing.

  • Patent number: 11305992
    Abstract: An ozone generation device includes an inverter, an ozone generator, and a reactor. The inverter turns on and off a switching element by pulse width modulation (PWM) control to convert DC power into AC power. In the ozone generator, voltage of the AC power is applied to a dielectric electrode, and discharge is generated in raw material gas flowing in a discharge gap between the dielectric electrode and a metal electrode, so that ozone is generated by the discharge. The reactor is connected in series to a dielectric electrode, and reduces an inrush current that flows through the dielectric electrode when the switching element is switched from off to on by the PWM control by the inverter.
