    摘要： An electrical contact with a fixed conductor and a movable conductor, comprises a plurality of plate springs, a plurality of contacts, the plate springs and the contacts being mounted into a single unit with an arrangement of those members in a substantial orthogonal relation to each other. The opposite ends of each of the plate springs being supported so as to provide an arrangement of contacts spaced at a fixed interval.

    摘要： The CPU of a test apparatus sends, to a subject test board, a test command containing an address in an address space where circuit blocks of the subject test board are mapped and a command code specifying an operation to be performed to the address. Test program executed by the CPU of the subject test board allow the CPU to extract the address and the command code included in the test command from the test apparatus and then to perform the operation specified by the command code to the address.

    摘要： Disclosed is an optical disc drive. The optical disc drive is provided with an arm member carrying an objective optical system and a light emitting system. The arm member is rotatable about an axis at one end portion thereof. On the other end portion of the arm member, the objective optical system is mounted. A detecting system is further provided for receiving light reflected by the optical disc via the objective optical system. The detecting system detects data related to an orientation of a beam spot formed by the reflected beam on its light receiving surface. Further provided is a control system which determines a current position of the arm member based on the data related to the orientation of the beam spot.

    摘要： Disclosed is an optical system for an optical disk drive for reading/writing data from/in an optical disk. The optical system includes a light source emitting a parallel laser beam, a deflector having a rotatable mirror surface. The parallel laser beam emitted by the light source is incident on the mirror surface of the deflector and is deflected towards an objective lens system which faces the optical disk. A relay lens system is provided between the deflector and the objective lens system such that the mirror surface and a front principal plane of the objective lens system have a substantially conjugate relationship.
