Abstract: A method of supplying lubrication oil to a two-stage screw compressor is disclosed in which a low-pressure stage screw compressor and a high-pressure stage screw compressor are integrally constructed. A compression space is formed by a male rotor and a female rotor, and operation gas is fed for compression to the compression space. The method prevents degradation of volumetric efficiency caused by return of lubrication oil, coming from a bearing and a shaft sealing device, to the low-pressure stage screw compressor, and as a result, refrigeration capacity is improved and the amount of the lubrication oil is reduced.

Abstract: To shorten a long aging time required for meat processing and reducing the viable cell count of a carcass before being cooked, an electric stimulus is imparted by applying an AC voltage via from electrode needles to at least the neck and legs of the meat carcass. The AC voltage is turned on for a time Ton and then turned off for a time Toff, and the application of the voltage is repeated a predetermined number of cycles. The Ton period is not longer than the Toff period, although the first Ton period can be longer than the Toff period. The voltage is not higher than 100V, and the frequency is not higher than the commercial frequency (maximum, 60 Hz). The aging effect is improved by stimulating the entire meat carcass electrically from at most three points.
