Abstract: An optical apparatus includes a light emitting apparatus and a host apparatus. The light emitting apparatus includes a housing extending in a first direction, a light emitting device mounted in the housing, an optical connector including a first optical connection part provided at one end of the housing, and an electrical connector including a first electrical connection part provided at one end of the housing and receiving a voltage to drive the light emitting device. The host apparatus includes a host optical connector including a second optical connection part which faces the first optical connection part and is optically coupled thereto, a host electrical connector including a second electrical connection part facing the first electrical connection part and being electrically connected to the first electrical connection part, and a host board mounting the host optical connector and the host electrical connector thereon.

Abstract: The disclosure provides a cable connection structure of a power control unit that can improve the work efficiency of assembling the power control unit. A power control unit 10 is attached to an upper portion of a motor case 12 that houses a motor. The power control unit 10 has a unit-side terminal 24 connected to a power supply passage inside the power control unit 10. The motor case 12 has a cable-side terminal 20 connected to a power supply cable. The unit-side terminal 24 and the cable-side terminal 20 are arranged to face each other in an up-and-down direction at an abutting portion between a lower surface of the power control unit 10 and an upper surface of the motor case 12. The unit-side terminal 24 and the cable-side terminal 20 are connected to each other via a conductive spring member.

Abstract: A rotating electric machine unit including a connector holding six connecting terminals is provided. When viewed from an axial direction, respective one-end parts of first to third connecting terminals are arranged side by side in a row. When viewed from the axial direction, respective one-end parts of fourth and fifth connecting terminals are arranged to offset to a back side of a first row composed of the first to third connecting terminals, and the one-end parts protrude further inside a casing than the one-end parts of the connecting terminals of the first row. When viewed from the axial direction, a one-end part of a sixth connecting terminal is arranged to offset to a back side of a second row composed of the fourth and fifth connecting terminals, and the one-end part protrudes further inside the casing than the one-end parts of the connecting terminals of the second row.

Abstract: A process for preparing optically active secondary alcohols of the general formula (3), [wherein R1 is linear lower alkyl, an aromatic ring group, or the like; A is CH2NR2R3 or the like; n is an integer of 0 to 2; and * represents an asymmetric carbon atom] by asymmetrically hydrogenating a ketone compound of the general formula (1) having nitrogenous or oxygen functional group at any of the a-, &bgr;- and &ggr;-positions, with selectivity among functional groups by the use of a ruthenium/optically active bidentate phosphine/diamine complex as the catalyst in the presence of hydrogen alone or together with a base. The optically active secondary alcohols obtained by the process are useful as drugs and intermediates for the preparation of drugs.
