Provided is an air conditioner which has a separator with an oil tank for storing extra oil; a first oil return tube opening above the surface of the extra oil; and a second oil return tube opening below the surface of the extra oil. When the refrigeration cycle cannot maintain the required oil dilution ratio as a result of the refrigerant having been replenished to cope with long piping, extra oil can be supplied from the second oil return tube to maintain the required oil dilution ratio in the refrigeration cycle, while using a highly versatile general compressor.

A signal output device includes a first selection unit operable to select a plurality of signal lines from a signal line group, a second selection unit operable to select a reference clock of signals carried by the selected signal lines, a determination unit operable to determine an output clock based on the reference clock and the number of selected signal lines, and an output control unit operable to sample the signals carried by the selected signal lines on every cycle of the reference clock and to sequentially output the sampled signals on every cycle of the output clock.

A memory control device for arbitrating memory access contention among bus masters while ensuring, regarding each bus master, the required transfer rate within the required time margin. A device external to LSI writes into the transfer rate information storage unit the transfer rate information indicating the transfer rate and the time period within which the transfer rate is to be ensured. In response, the timing information generator unit determines the shortest time period as a cycle, and also determines, regarding each bus master, time taken to ensure the required transfer rate based on the memory bus bandwidth as a bus use permission time period. The arbiter unit grants the bus use right sequentially with the passage of time to each bus master issuing a bus request for the corresponding bus use permission time period.

In a hermetic motor-driven compressor, a first gas passage is formed by a space between a linear section in a motor stator and a hermetic container, and a second gas passage in parallel with the first gas passage is formed by through holes in the motor stator. The through holes constituting the second gas passage are disposed outside of a circle inscribed in the linear section in the stator. The through hole is shaped like a bow, and an arch shape of the outer periphery thereof has a curvature larger than that of the outer circumference of the stator.

The remote control signal reception controller receives control data transmitted from a remote control signal sender. The remote control signal reception controller informs a CPU that controls a device of the information on the received control data by interrupting the CPU. When doing so, the remote control signal reception controller judges whether a piece of control data that has just been received and a preceding piece of control data were consecutively transmitted, and whether these two pieces of control data are the same control data. The remote control signal reception controller interrupts the CPU only once when finding that the same control data is continuously transmitted as the result of this judgement.
