    摘要: The objective of the present invention is to produce a novel (R)-2,3-butanediol dehydrogenase useful for the production of ketones, alcohols, and particularly optically active vicinal diols. It has been found that Pichia angusta produces novel (R)-2,3-butanediol dehydrogenase that shows the high activity and high stereoselectivity. Further, polynucleotide encoding this (R)-2,3-butanediol dehydrogenase was cloned, and the nucleotide sequence thereof was determined. The expression of the glycerol dehydrogenase was carried out in heterologous microorganisms.

    摘要: A clutch comprises a driving rotor (11; 52; 83; 202; 302) coupled to a driving source (2) such as a motor, and a driven rotor (12; 53; 85; 204; 303) directly engaged with the driving rotor. Both rotors are accommodated in a housing (13; 51; 82; 201; 301). A lock member (14; 54; 86; 119; 205; 304) comprised of rollers or balls is located between the driven rotor and the housing. When the driven rotor itself is rotated, the lock member is held between the driven rotor and the housing to block the rotation of the driven rotor relative to the housing. When the driving source rotates the driving rotor, the lock member is released from the held state to allow the driving rotor to rotate the driven rotor relative to the housing. Such a clutch can block the transmission of the rotation from the driven rotor to the driving rotor without fail, and can reduce the strength required to both rotors.

    摘要: In a motor device for vehicles, a brush holder is interposed between a motor yoke housing and a reduction gear unit housing has a holder body and a connector unit integrally formed with each other. The connector unit holds therein connector terminals having base ends connected to brushes. A sealing cover is molded integrally on the holder body and the base ends of the connector terminals. The sealing cover seals insides of the yoke housing and the gear housing water-tightly from the outside. The sealing cover is preferably made of rubber, elastomer or adhesive resin, and formed with the brush holder by two-color molding. The sealing cover has a cylindrical cover part extending from the connector unit, and the motor device is mounted in a vehicle door with the cylindrical cover part being attached to the vehicle door for electrical connection with an external power source.
