摘要： PROBLEM TO BE SOLVED: To avoid a serious accident of igniting and exploding a hydrocarbon refrigerant, by mixing the refrigerant and a refrigerating machine oil with a coloring ink, and mounting at a connector of piping or the like a member for absorbing and discoloring leaked coloring ink. SOLUTION: A hydrocarbon(HC) mixed with a coloring ink and a refrigerating machine oil are sealed in a refrigerating cycle. Further, a discoloring member made of a cellulose fiber material or the like and having a thickness of about 0.5 to 1.0 mm is mounted at each of connecting parts 19, 19a, 20 of piping or the like. The member absorbs a refrigerant and a refrigerating machine oil when the refrigerant and the oil colored by the ink are leaked, and discolored to red, blue or the like. When the member absorbs the refrigerant and the oil, its leakage becomes apparent. Thus, leakage of the HC refrigerant can be visually sensed, the HC refrigerant can avoid a serious accident of igniting and exploding the refrigerant.

摘要： PROBLEM TO BE SOLVED: To improve translation efficiency by outputting a voice recognition result before the voice recognition result is translated and starting translating by a translating means after it is confirmed that the voice recognition result is correct. SOLUTION: When the voice spoken by an operator is inputted to a voice recognition part 12 after converted to an electric signal by a microphone 11, a voice recognition part 12 performs voice recognition by referring to a dictionary for recognition in a recognition dictionary storage part 17. After this voice recognition, the voice recognition result is transmitted to a voice synthesis part 15 after a translation part 13 starts translating operation and a voice is synthesized there and outputted from a speaker 16. The operator can confirm whether or not the voice recognition has been done by the voice recognition part 12 by hearing the voice outputted from the speaker 16. In this case, the operator answers 'Yes' in front of the microphone 11 when the voice recognition result is correct. In response to that, the translation part 13 starts translating.

摘要： PURPOSE: To obtain a refrigerator which uses a refrigerator oil highly compatible with a refrigerant mainly comprising a fluorocarbon contg. no chlorine (e. g. HFC-134a). CONSTITUTION: This refrigerator is applied for a refrigeration cycle consisting of a compressor 40, a condenser 41, an expansion mechanism 42, and an evaporator 43, uses a refrigerant mainly comprising a fluorocarbon contg. no chlorine and having a critical temp. of 40 deg.C or higher, and uses a refrigerator oil of which the base oil is a fatty acid ester having a viscosity of 2-70cSt at 40 deg.C and 1-9cSt at 100 deg.C and at least two ester bonds (-OCO-) in the molecule. The refrigerator oil, highly compatible with the refrigerant, exhibits an excellent lubricity and enables a highly reliable refrigerating cycle to be realized.

摘要： PURPOSE:To prevent a carbide from being formed in a discharge valve as well as to secure good sealability over a long period of time, by forming an oil-repellent resin layer on a surface of the discharge valve in a compressive mechanism part, in the case of the compressor that housed an electric motor and the compressive mechanism part in a case. CONSTITUTION:A compressor to be used for a refrigerator or the like has a compressive mechanism part, housing a rotor 6 to be rotated by the electric motor housed in a common vessel via a crankshaft 11 in a cylinder 5. This compressive mechanism part, in turn, has a discharge valve 3 discharging the refrigerant gas compressed at time of completion of a compression stroke, at the lower bearing 1. This discharge valve 3 consists of a lower discharge valve 3a and an upper discharge valve 3b, and its opening limit is regulated by a retainer 2 to be positioned in the outermost part. In this case, an oil- repellent resin layer consisting of a fluororesin polymer or the like such as ethylene polytetrafluoride, etc., is formed on a surface of the lower discharge valve 3a, whereby a carbide is prevented from being formed on the surface.

摘要： PROBLEM TO BE SOLVED: To provide a new method of using a refrigerating cycle. SOLUTION: In this method of using the refrigerating cycle constituted of at least a compressor 40, a condenser 41, an expanding mechanism 42, and an evaporator 43 and using a chlorine-containing halocarbon refrigerant, at least part of the halocarbon refrigerant is replaced with another halocarbon refrigerant containing no chlorine. Preferably, used refrigerating machine oil is constituted of refrigerating machine oil using fatty ester oil having a critical temperature of >=40 deg.C, viscosities of 2-70 cSt at 40 deg.C and 1-9 cSt at 100 deg.C, and at least two ester linkages (-O-CO-) in its molecule as base oil. Consequently, a new refrigerating cycle can be realized by only exchanging at least either one of the refrigerant and refrigerating machine oil of the conventional refrigerating cycle.
