  • Publication number: 20240083398
    Abstract: A driving assist apparatus comprises a sensor for detecting an object located in front of a vehicle and moving in the same direction as the vehicle, and a controller for executing a brake control for applying a brake force to the vehicle during a time from a time point at which the obstacle satisfies a predetermined start condition to a time point at which a predetermined end condition is satisfied. The controller is configured to set a target stop distance such that the target stop distance increases as a relative speed of the object with respect to the vehicle increases when the controller executes the brake control, and apply the brake force so that the vehicle stops when a distance between the object and the vehicle coincides with the target stop distance.

  • Publication number: 20220069590
    Abstract: The standby power supply device includes one or more secondary batteries and a charging circuit that charges the secondary batteries. The charging circuit includes a voltage adjuster that controls the state of charge of the secondary batteries, and a controller that controls the voltage adjuster by detecting the degree of deterioration of the secondary batteries over time. In the charging circuit, the voltage adjuster charges the secondary batteries at a charge voltage lower than a full charge voltage of the secondary batteries to bring the secondary batteries into a load power supply standby state, and gradually increases the charge voltage of the secondary batteries according to the degree of deterioration of the secondary batteries detected by the controller.

  • Patent number: 7378062
    Abstract: A processing apparatus for subject of the present invention uses a high voltage electrode and a ground electrode, and generates plasma under atmospheric pressure in a reaction passage through which a to-be-processed subject passes. For example, even fluorocompound such as PFC including CF4 can effectively be decomposed because the fluorocompound is brought into contact with plasma in a small space for sufficient time, and the apparatus has a small and simple structure. Therefore, the apparatus can be added to each process chamber.
