    摘要： A voltage polarity determination circuit includes an integration circuit, a switch, and a time measurement circuit. The integration circuit includes an operational amplifier circuit having an input offset voltage which is larger than the maximum value of a voltage input to the integration circuit or smaller than the minimum value of the input voltage of the integration circuit. The switch switches the input voltage of the integration circuit between a voltage whose polarity is to be determined and a reference voltage. The time measurement circuit measures a time interval which it takes for the output voltage of the integration circuit to reach a set voltage, and based on the result of the measurement, determines the polarity of the input voltage of the integration circuit.

    摘要： In a vehicle air-conditioning device, refrigerant leakage is diagnosed precisely without any restrictions from an operating condition of the air-conditioning device. When the operating condition of the vehicle air-conditioning device is stable, a threshold value Th for determination of refrigerant leakage is set based on an outlet pressure Pd and an inlet pressure Ps of a compressor. Furthermore, a volume flow Gr in that refrigerant pipe running from a condenser to an expansion valve through which the refrigerant circulates in a liquid state is detected. When it is determined that the volume flow Gr exceeds the threshold value Th for determination of refrigerant leakage, a diagnosis result (alarm) indicating that the refrigerant leaks is output.

    摘要： Provided is a refrigeration cycle wherein, when an orifice is disposed within a refrigeration circuit, and a differential pressure between the upstream side and the downstream side of the orifice is detected using two pressure sensors, the difference between the characteristics of the pressure sensors can be adequately and easily absorbed in software, to accurately determine an actual differential pressure, so that the flow rate of refrigerant and the torque of a compressor can be accurately estimated. The refrigeration cycle wherein the orifice is provided within a refrigerant circuit, and the pressure sensors are respectively provided on the upstream side and the downstream side of the orifice, is characterized in that, with regard to output characteristics representing the relationship between the detected pressure and the sensor output of each pressure sensor, the difference between the output characteristics of one pressure sensor and the output characteristics of the other pressure sensor is determined based on the outputs of both pressure sensors at a condition where the flow of refrigerant is stopped.

    摘要： In a controller device, when a first transmitting signal is at a “L” level, a first operation voltage is high and the amplitude of signals CK and ICK is large, and on the contrary, the amplitude is small when the first transmitting signal is at a “H” level. In a data carrier device, the signals CK and ICK are subjected to full-wave rectification by a rectifier circuit so as to generate a second operation voltage, and a first receiving signal is extracted from the second operation voltage by a first signal detection circuit. On the other hand, in the data carrier device, when a second transmitting signal is at a “L” level, impedance between two contacts is small and the amplitude of the signals CK and ICK is small, and on the contrary, the amplitude is large when the second transmitting signal is at a “H” level. In the controller device, change of the amplitude of the signal ICK is extracted as a second receiving signal by a second signal detection circuit. Accordingly, supply of power and clock and two-way serial data communication can be simultaneously executed between the controller device and the data carrier device through merely two contacts.

    摘要： An air conditioner for vehicles that prevents icing and lack of visibility from developing on window glass of a vehicle during heating, and which permits a dehumidifying operation to be made without lowering of the air blowing temperature. The air conditioner is of a heat pump type comprising a compressor, an exterior heat exchanger, and a first interior heat exchanger, which are provided together with a second interior heat exchanger used as a heat radiator at least during heating. Further, piping lines are provided for introducing a refrigerant gas for passage through the second interior heat exchanger to the exterior heat exchanger through an expansion means, and for introducing the refrigerant gas for passage through the second interior heat exchanger to the first interior heat exchanger through a first expansion means. Thus, dehumidification in the vehicle can be simultaneously performed during heating by respectively performing a heat radiating operation at the second interior heat exchanger and a heat absorbing operation at the first interior heat exchanger.
