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.

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.

A substrate holding apparatus can meet the request for a smaller-sized compact apparatus while ensuring a sufficient immersion depth of a substrate in a processing liquid. The substrate holding apparatus includes: a substrate holder for supporting a substrate (W) by bringing a peripheral portion of a surface of the substrate (W) into contact with a first sealing member; and a substrate pressing section for lowering relative to the substrate holder so as to press the substrate (W) held by the substrate holder downward, thereby bringing a first sealing member into pressure contact with the substrate (W). The substrate pressing section is provided with a second ring-shaped sealing member which makes pressure contact with an upper surface of a ring-shaped holding section of the substrate holder, thereby sealing the peripheral region of the substrate pressing section.

An air conditioner includes a fixed displacement-type first compression mechanism and a variable displacement-type second compression mechanism independent from each other in a refrigeration cycle, and further includes second compression mechanism displacement control means, compression mechanism operation switching control means, an evaporator for refrigerant, a condenser, a blower, evaporator temperature detection means, and evaporator target temperature calculation means. When the refrigeration cycle is operated only by the first compression mechanism, referring to a temperature (Teva) detected by the evaporator temperature detection means, a temperature (Toff) calculated by the evaporator target temperature calculation means and a predetermined value A, if a condition of Teva−Toff≧A is satisfied, both compression mechanisms are operated simultaneously. The condition of required cooling ability is properly determined, an optimum control for air conditioning is realized, and the loss of consumption power and the like can be adequately suppressed.

A battery having an electrode unit in which edges of electrode plates are mechanically and electrically connected to a fixing and conducting plate is obtained. A projection is formed at an edge of each electrode plate, and projections are inserted into a grove formed on the fixing and conducting plate. Energy beam is radiated to the fixing and conducting plate along a wall defining the groove, and metal forming the groove is melted and fills a gap between the projection and the groove. The filling metal is solidified at a condition that the melted metal surrounds the projection. The electrode plate is firmly connected to the fixing and conducting plate by a combination of the projection and the surrounding metal. The electrode plates are stably maintained at a positional relationship that the electrode plates extend parallel with each other leaving a gap between adjacent electrode plates, and the electrode plates are connected to the fixing and conducting plate with a reliable electric conductivity.
