  • Publication number: 20240123834
    Abstract: A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated. The information acquisition unit acquires information on a state of the vehicle. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.

  • Publication number: 20230307258
    Abstract: A substrate processing apparatus includes a first tank, a path including a first path, a first heater, a hydrogen peroxide supply path, and a controller. The first path allows sulfuric acid to be supplied therethrough from the first tank to a nozzle. The first heater heats a heating region of the first path. The controller controls ejecting sulfuric acid heated by the first heater and a hydrogen peroxide solution from the nozzle onto a substrate, the sulfuric acid and the hydrogen peroxide solution on the substrate having been mixed, and then ejecting sulfuric acid having a temperature lower than a temperature of the sulfuric acid heated by the first heater and the hydrogen peroxide solution from the nozzle onto the substrate, the sulfuric acid and the hydrogen peroxide solution on the substrate having been mixed.
