Abstract: A multistage compression system uses refrigerant and oil. The multistage compression system includes a low-stage compressor that compresses the refrigerant, a high-stage compressor that further compresses the refrigerant compressed by the low-stage compressor, and an oil return pipe that returns the oil discharged by the high-stage compressor or the oil in the high-stage compressor to the low-stage compressor. The low-stage compressor has a rotary compression part that compresses the refrigerant, a motor that drives the compression part, and a container housing the compression part and the motor. The motor is disposed above the compression part. The oil return pipe is connected to a space below the motor inside the container.

Abstract: According to one embodiment, an automatic analyzing apparatus includes a probe and a liquid level detector. The liquid level detector is electrically connected to the probe and detects contact between the probe and a liquid surface, wherein the liquid level detector comprises an adjuster configured to adjust electrostatic capacitance of one or more capacitors for circuitry for use in liquid level detection.

Abstract: A tempering treatment method whereby the temperature of meat, which involves a carcass prepared by slaughtering cattle or poultry and sterilizing and washing, is lowered as close to the ice storage temperature as possible to prevent a temperature rise caused by the actions of enzymes contained within the meat before transporting the meat to a refrigerated storage, which comprises surface-freezing the meat by blowing a cold air stream at about ?20 to about ?40° C. to the meat before conducting the tempering treatment, thus allowing the generation of freezing latent heat in the subcutaneous part owing to the surface-freezing (freezing the subcutaneous tissue), and then rapidly lowering the core temperature inside the meat due to the latent heat released at the melting of the freezing latent heat to thereby conduct the tempering treatment at a temperature of 0 to +15° C.
