  • Patent number: 8152574
    Abstract: Upon fitting of the first housing 10 and the second housing 50, joints 21, 63 of the two terminals 20, 60 are superposed in the fitting portion 11, the two joints 21, 63 having respective bolt-insertion holes 21A, 63A that allow for insertion of a bolt V thereinto so that the two joints 21, 63 are fixed together. The fitting portion 11 of the two housings 10 has an operation hole 23 that allows for bolting of the two terminals 20, 60. A first shield shell 40 is attached to the first housing 10. The first shield shell 40 is fixable to the case. A second shield shell 70 is attached to the second housing 50. The second shield shell 70 in a fitted state of the two housings 10, 50 is slidable between: a position to expose the operation hole 23 to the outside; and a position to cover the operation hole 23 and to cooperate with the first shield shell 40 to cover the fitting portion 11.

  • Publication number: 20110187213
    Abstract: A rotary electric machine terminal block fits into an opening of a case that contains a rotary electric machine, and is fixed to the case by a plate. The rotary electric machine terminal block has: a mount that is formed by fixing the electric power line connector and the signal line connector to the steel-made plate and performing insert molding so that an anti-vibration plate is formed on an upper surface of the plate; projected portions of the plate which each have a fixture hole for fixing the plate to the case; an edge seal member that covers an edge of the projected portion; a face seal member for tight attachment of the mount to the case; and two positioning pins.

  • Publication number: 20110096007
    Abstract: An operation processing system capable of attaining operation inputting to a touch panel device fast with high security, in which upon receiving finger image data imaged by the touch panel device with position information of a finger area detected by a point detection part taken as an imaging range form the touch panel device, an authentication part in the operation processing system authenticates the received finger image data, and when the authentication conducted by the authentication part has succeeded, an operation processing part acquires an operation to the operation object located in position information detected by the point detection unit from a control table of operation authentication and outputs the operation.

  • Publication number: 20100255728
    Abstract: First and second housings (10, 50) are fit together so that joints (21, 63) of two terminals (20, 60) are superposed in a fitting portion (11) of the first housing (10). The joints (21, 63) have bolt-insertion holes (21A, 63A) that allow insertion of a bolt V to fix the joints (21, 63) together. The fitting portion (11) has an operation hole (23) that allows bolting of the two terminals (20, 60). A first shield shell (40) is attached to the first housing (10) and is fixable to a case. A second shield shell (70) is attached to the second housing (50) and is slidable between a position to expose the operation hole (23) to the outside and a position to cover the operation hole (23) and to cooperate with the first shield shell (40) to cover the fitting portion (11).
