  • Patent number: 5953025
    Abstract: An ink jet printer has a print head adapted to move in a printing area and in a wiping area outside of the printing area. The print head ejects ink drops through orifices in accordance with print data while it is moving in the print area. The wiper is disposed in the wiping area. The nozzle plate having orifices formed therethrough is wiped off when the print head moves in the wiping area. A wiper transporting mechanism includes a supporting mechanism for supporting and moving the wiper parallel with the print head when the print head moves in the wiping area, the wiper being transported at a velocity lower than the print head so that the wiper gently wipes the nozzle plate preventing the ink adhering to the wiper from splashing.

  • Patent number: 5718120
    Abstract: A vehicle air-conditioning system which operates in response to the manipulation of momentary switches is provided with discriminating means for discriminating whether any momentary switch is on at the time of system power-up. When the discriminating means finds that one or more momentary switches are on, the vehicle air-conditioning system is set to a predefined initial control state independent of contact information from such momentary switch or switches. As a result, at least the minimum temperature control required for occupant comfort can be secured when shorted contact sticking occurs in a momentary switch provided on an operation panel.

  • Patent number: 5148685
    Abstract: In an air conditioner including a variable-capacity compressor, a control system performs a PI calculation based on a temperature deviation between the actual temperature of the air downstream of an evaporator and its target temperature, thereby determining a control amount for controlling the capacity of the compressor. It is judged whether or not the sum of a proportional control component and an integral control component exceeds a limit value of the control amount corresponding to the maximum capacity of the compressor. If this judgment is in the affirmative, an ordinary integral calculation is stopped, and the integral control component is determined by subtracting the proportional control component from this limit value.

  • Patent number: 5117643
    Abstract: An automobile air-conditioner capable of controlling the displacement of a compressor in view of the traveling condition and air-conditioning condition of an automobile so as to maintain a pleasant feeling of the air-conditioning and an accelerating ability of the automobile in harmony with each other. The air-conditioner includes an air-conditioning preference judgment device by means of which a normal control of the air-conditioning operation is maintained when the judgment of this judgment means indicates the existence of an air-conditioning preference condition. The air-conditioning is performed in preference to acceleration of the automobile depending on the degree of acceleration of the automobile even when the automobile is accelerated.

  • Patent number: 5074123
    Abstract: An air conditioning control system for an automotive vehicle having an internal combustion engine. A variable capacity compressor has a pump having displacement thereof variable in response to a change in pressure within a controlled pressure chamber, a communication passage communicating between a low pressure chamber and the controlled pressure chamber, and a valve disposed to vary an opening area of the communication passage. An electromagnetic clutch connects and disconnects the compressor to and from the engine. An evaporator is connected to the compressor. A control unit controls the capacity of the compressor by supplying the valve with control current normally set within a predetermined range, to vary the opening area of the communication passage such that the temperature of outlet air from the evaporator becomes equal to a desired value.

  • Patent number: 5020424
    Abstract: An apparatus for controlling an automotive air-conditioner wherein an air distribution to left and right sides of a vehicle passenger compartment is achieved either in an automatic control mode or in a manual control mode which is selected by a judgement made based on the vehicle passenger compartment and the quantity of solar radiation. In case of the automatic control mode, the rate of change of the air distribution control is changed dependent upon the position set by an air-distribution setting unit relative to the direction of solar radiation so as to meet the occupant desire.

  • Patent number: 4898005
    Abstract: A method of controlling the idling rotational speed of an internal combustion engine for an automotive vehicle equipped with an air conditioning system having a variable capacity compressor disposed to be driven by the engine and capable of being controlled by an external control signal. A value of a capacity control signal as the external control signal for controlling the capacity of the compressor is calculated. A value of torque required for starting the compressor is calculated based upon ambient temperature and the calculated value of the capacity control signal. The engine idling rotational speed is increased in accordance with the calculated starting torque.

  • Patent number: 4858677
    Abstract: An automobile air-conditioning apparatus with air blower control air-conditions the passenger compartment of an automobile by cooling and/or heating air delivered from an air blower into the compartment. During a period in which the compartment starts being cooled, the rate of air flow form the air blower is progressively increased up to an air flow rate in an automatic temperature adjusting mode. The gradient at which the air flow rate is increased is selected dependent on the amount of sunlight applied to the automobile, the temperature of air in the compartment, and the temperature of air at the outlet of an evaporator.
