Abstract: A screw compressor has a screw rotor and a cylinder having an economizer port. The economizer port communicates with a compression chamber formed between the screw rotor and the cylinder. The economizer port is configured and arranged to jet a refrigerant into the compression chamber before closing the compression chamber. Accordingly, the economizer is in communication with the compression chamber while the inner pressure of the compression chamber is low.

Abstract: Provided is a process for producing a seasoning having an excellent roast meat like flavor without unpleasant odor derived from yeast and burnt odor derived from saccharide. The process comprises the steps of mixing a yeast extract containing at least one of cysteine, cystine, methionine, glutathione, ?-glutamylcysteine, cystebylglycine, and salts or hydrates thereof with saccharide and/or a nucleic acid-related substance to prepare a mixture; and heating the mixture under different pH conditions.

Abstract: A flavor of smoke generated by combustion, incomplete combustion, or thermal decomposition of a plant material may be improved by heating the smoke with a secondary heater. In particular, a dried smoked fish may be produced by drying boiled fish by a hot blast for a predetermined time so as to reduce a water content thereof to 30% or less by mass, and keeping the dried fish under an atmosphere of the smoke with the improved flavor. The temperature of hot blast is preferably decreased from 120° C. or higher at the initial drying step, to lower than 120° C. at the final drying step. According to this method, a favorable flavor is imparted to the food, and toxic ingredients such as benzopyrene are reduced.

Abstract: A screw compressor has a screw rotor (10) and a cylinder (11) having an economizer port (12). The economizer (12) communicates with a compression chamber (13) before closing the compression chamber (13) between the screw rotor (10) and the cylinder (11). Accordingly, the economizer port (12) can be communicated with the compression chamber (13) while the inner pressure of the compression chamber (13) is low. Thereby, the amount of a refrigerant jetted form the economizer can be increased. Cooling effect by a refrigerant is enhanced by increasing the amount of the refrigerant jetted from the economizer port.

Abstract: A compound represented by the following general formula (1): wherein R1 represents a halogen atom, R2 represents hydrogen atom or a lower alkyl group, and R3 represents hydrogen atom, a lower alkyl group, a lower alkoxyl group, a hydroxy lower alkyl group, a halogen atom, or a substituted or unsubstituted amino group, wherein a substituent on the amino group is selected from the group consisting of a lower alkyl group, a lower alkenyl group, a lower alkylcarbonyl group, and an amino protective group, or a salt thereof. The compound of the present invention or a salt thereof is useful as an active ingredient of medicaments for preventive and/or therapeutic treatment of conditions of irritable bowel syndrome and digestive tract functional disorder, or condition of diarrhea.
