Abstract: A refrigerant being low in both ODP and GWP and containing at least hydrofluoroolefin having a double bond of carbon is used. By providing a first compression-chamber oil feed path for feeding refrigerating machine oil to a compression chamber 15 after the refrigerant has been enclosed therein, effects on the global environment can be suppressed and moreover temperature increases of the refrigerant due to re-expansion heating and feeding of high-temperature refrigerating machine oil can be suppressed, i.e., decomposition of the refrigerant can be inhibited.

Abstract: A scroll compressor employs therein a refrigerant having a small global warming potential and a small ozone depletion potential and mainly comprising hydrofluoroolefin having a carbon-carbon double bond. A stationary scroll has and end plate and a discharge port defined in the end plate at a central portion thereof so as to open into a discharge chamber. The stationary scroll also has a bypass hole defined in the end plate to allow a plurality of compression chambers to communicate with the discharge chamber before the compression chambers communicate with the discharge port. A check valve is provided on the bypass hole to allow the refrigerant to flow from the compression chambers to the discharge chamber. This construction can restrain a baneful influence on the global environment, reduce a temperature increase caused by excessive compression, and restrain decomposition of the refrigerant even in long-term use.

Abstract: When an operational mode is shifted to a standby mode, a first transistor is brought into a conduction state by a control signal, and a word line is thereby clamped to a ground voltage. Further, a second transistor is brought into a non-conduction state, and supply of an internal power supply voltage to a word line driver is shut off. Subsequently, the supply of the internal power supply voltage is halted for saving electrical power. When the operational mode returns to a normal mode, the supply of the internal power supply voltage is started, and subsequently, the first transistor is brought into the non-conduction state by the control signal, and the second transistor is thereby brought into the conduction state.

Furthermore, the primary data and the secondary data are outputted to the output unit while correlating them to each other.
