    摘要: The expander-compressor unit 70 includes the closed casing 1, the expansion mechanism 4 disposed in the closed casing 1 so that a surrounding space thereof is filled with the oil, the compression mechanism 2 disposed in the closed casing 1 so as to be positioned higher than the oil level, the shaft 5 for coupling the compression mechanism and the expansion mechanism 4 to each other, and the oil flow suppressing member 50 disposed in the surrounding space of the expansion mechanism 4 so that the space 55a filled with the oil is formed between the expansion mechanism 4 and the oil flow suppressing member 50. Thereby the flow of the oil filling the inner reserving space 55a is suppressed, and thus, heat transfer from the high temperature oil to the low temperature expansion mechanism can be reduced.

    摘要: A data communication function table relating to communication functions is shared between devices. Whether a communication device can operate in an autonomous communication mode or request/response communication mode can be therefore determined, the data type can be determined, the data size and data identification information can be acquired, and a file can be divided to an optimum size for transmission. Network traffic is therefore reduced and the effective communication speed is improved for data communication between devices over a network.
