An inverter transformer comprises an insulation bobbin (10) having a spool (12); a primary winding (30); and a secondary winding (4). A plurality of winding grooves (14) are defined by a plurality of flanges (13) provided on the side surface of the spool (12). The primary winding (30) is provided in one (14a) of the winding grooves (14). Another one (14b) of the winding grooves which has no winding provided therein is interposed between the primary winding (30) and the secondary winding (40).

Disclosed is a method for hydrating a cycloolefin, in which the hydration is conducted in a reaction system comprising a continuous aqueous phase including water and a crystalline aluminosilicate catalyst suspended therein and an oil phase including a cycloolefin, while dispersing the oil phase as globules having a specific diameter. By the method of the present invention, not only can a cyclic alcohol be produced at high selectivity and in high yield, but the activity of the catalyst can also be stably maintained at a high level for a prolonged period of time, and the produced cyclic alcohol can be readily separated.

The present invention provides a method for producing a fatty acid monoester product by reacting an animal oil and/or a vegetable oil with an alcohol in the presence of a sulfonic acid group-introduced amorphous carbon catalyst and water. By this method, the production of a fatty acid monoglyceride, which is difficult to separate from the fatty acid monoester, can be suppressed, and the fatty acid monoester can be efficiently produced.Also, the present invention provides a method for producing a fatty acid monoester product by performing the transesterification reaction of an animal oil and/or a vegetable oil with an alcohol, or the esterification reaction of a fatty acid with an alcohol, in the presence of a sulfonic acid group-introduced amorphous carbon catalyst washed with water. By this method, the life of the catalyst can be extended, and the production cost can be reduced.
摘要:
A fusion protein comprising a carrier and a desired peptide or protein linked to the carrier via an enzymatically excisable dipeptide, such as Lys-Arg, is produced in a host microorganism and then the desired peptide or protein is recovered by treating the fusion protein at least with a protease specifically recognizing the dipeptide and specifically hydrolyzing the peptide bond of the dipeptide. The fusion protein includes tandem-form fusion proteins in which desired peptide or protein molecules are linked together repeatedly. According to the cleavage site in the dipeptide, the protease may be used in combination with an aminopeptidase specifically releasing a basic amino acid from the N-terminal side of the dipeptide and/or a carboxypeptidase specifically releasing a basic amino acid from the C-terminal side of the dipeptide.

An exhaust gas containing nitrogen oxides is efficiently purified without the necessary use of catalysts by contacting the exhaust gas with a nitrile compound at high temperature in the presence of oxygen, whereby the nitrogen oxides and the nitrile compound are selectively decomposed into harmless materials.

The present invention relates to a gas safety control system for supplying a gas that is forwarded from a gas supply source through an inspection meter to one or more gas appliances. The inspection meter comprises a cutoff valve for cutting off supply of the gas from the gas supply source, a detection unit for detecting such abnormal condition as gas leakage and abnormal flow rate of the gas, a valve control unit for actuating the cutoff valve when the detection unit detects an abnormality and a meter communication unit for outputting cutoff information indicating that the supply of gas is cut off by the cutoff valve. The gas appliance comprises an appliance communication unit for communicating with the meter communication unit and a combustion disabling unit for switching the gas appliance to a combustion disabled state, if it is in a combustion enabled state, when the cutoff information is received through the appliance communication unit. In the gas safety control system constituted in such manner, because the supply of gas and operation of the gas appliance are automatically discontinued when such abnormality as gas leakage is detected, gas explosion, gas poisoning and like accidents can be prevented.
摘要:
Disclosed is a method for partially hydrogenating a monocyclic aromatic hydrocarbon to produce a cycloolefin, comprising reacting a monocyclic aromatic hydrocarbon with hydrogen in the presence of a particulate hydrogenation catalyst comprised mainly of metallic ruthenium, in a reaction system comprising a continuous aqueous phase having the particulate hydrogenation catalyst suspended therein, an oil phase containing the monocyclic aromatic hydrocarbon, and a gaseous phase comprising hydrogen gas, while applying a shearing force to the reaction system at a specific maximum shear rate. By the method of the present invention, not only can a cycloolefin be produced at high selectivity and in high yield, but also the catalytic activity can be stably maintained at a high level for a prolonged period of time.

A process for liquefying and gasifying coal by thermal treatment in the presence of hydrogen gas for hydrocracking is disclosed. The process comprises a sequence of the following two steps:(1) coal fines are injected into a heated hydrogen gas stream at a pressure of from 35 to 250 kg/cm G such that they are rapidly heated to a temperature of from 750.degree. to 1100.degree. C. for thermal cracking thereof; and(2) the resulting liquid product is subjected to hydrocracking for a period of from 1.0 to 60 seconds at a temperature that is lower than the temperature used in the first step and which is in the range of from 570.degree. to 850.degree. C.
