  • Patent number: 4825756
    Abstract: A controller for automotive air conditioner system includes first and second control units which are cooperable for controlling the condition of air supplied to the vehicular cabin. The first control unit has side edges, each of which engages the channel between horizontally extending rails formed on the inner surface of the side wall of the controller body. The first control unit can disengage from the channel to be detachable from the controller body so as to allow another control unit having edges of the same shape as those of the first control unit to be substituted for the first control unit.

  • Patent number: 4788043
    Abstract: Disclosed is a process for washing a semiconductor substrate with an organic solvent, which comprises the first stage of supplying an organic solvent to be used for the organic solvent washing of a semiconductor substrate to a washing device and washing the semiconductor substrate, the second stage of supplying the organic solvent containing water, electrolytes and particulate or clustery suspended substances, which has been withdrawn from the first stage, to a pervaporation device and separating and removing mainly water, and the third stage of supplying the organic solvent withdrawn from the second stage to a distillation device to obtain the organic solvent as a distillate and recycling the distillate as the organic solvent to the first stage, the three stages being combined to form a continuous circulation systems.

  • Patent number: 4640183
    Abstract: A movable air mix door serves to adjust the temperature of outgoing air from an air conditioner. The temperature of outgoing air depends on the position of the air mix door. A combination of a position sensor for sensing the actual position of the air mix door and a temperature sensor for sensing the temperature of incoming air into the air conditioner generates a first signal depending on the actual position of the air mix door and on the incoming air temperature. A second signal represents a target position of the air mix door. The position of the air mix door is controlled by a controller in accordance with the first and second signals. Since the combination sensor produces a signal dependent on incoming air temperature, the processing load on the controller is reduced in that the controller itself need not correct the target position in accordance with the incoming air temperature.
