  • Patent number: 10744842
    Abstract: A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.

  • Patent number: 10744852
    Abstract: A vehicular air-conditioning device includes a blowing port mode door as an air volume regulator that regulates volumes of air-conditioning air blown to a driver seat area, a front passenger seat area, and a rear seat area inside a vehicle compartment, and an air-conditioning controller activated by an activation signal outputted from a body controller in response to opening and closing of a rear seat door during a stoppage of a vehicle system. The air-conditioning controller is capable of operating an actuator for driving the blowing port mode door to blow the air-conditioning air to the rear seat area when an activation switch of the vehicle system is turned on in a state where the air-conditioning control unit has been activated by the activation signal.

  • Patent number: 8573579
    Abstract: Methods and apparatus are provided for static-biasing a pre-metalized non-conductive substrate within a process chamber. A substrate holder that holds a pre-metalized non-conductive substrate is engaged by a lift mechanism that provides movement of the substrate in a first, upward direction to a contact position within the process chamber and in a second direction to a non-contact position. When the substrate holder is moved to the contact position, the substrate electrically engages a conductive spring-loaded compliance mechanism that is mounted in a fixed position within the process chamber. The spring-loaded compliance mechanism is connected to a bias-voltage feed-through for the process chamber that applies a bias voltage to the substrate via the spring-loaded compliance mechanism.
