    摘要: An electrostatic discharge protection device is disclosed for use with a printed circuit board (hereafter referred to as "PCB") of the type having a major portion and a dependent integral tongue having oppositely disposed PCB surfaces with conductor pads disposed thereon. The electrostatic discharge protection device comprises a first hinge structure and a second hinge structure mounted to corresponding PCB surfaces. Each hinge structure has a base section securely mounted to the PCB surface, an elongated arm section pivotally connected to the base section and having an electrically conductive bar disposed along the length thereof, and means for urging the electrically conductive bar against and into electrical interconnection with the conductor pads while the PCB remains disconnected from a complementary edge connector. The PCB's subsequent mating with the edge connector operates to pivot the arm section away from the base section so as to electrically and physically disengage the electrically conductive bar from the conductor pads.

    摘要: An electrostatic discharge protection device is disclosed which selectively shunts charge accumulation across electrical conductors emplaced within the device housing. A grounding element is provided on the housing surface which maintains electrical contact with the enclosed electrical conductors so as to form a shorting shunt and place the conductors at substantially similar electrical potentials. The grounding element may be reversibly changed from the operative into an inoperative position to remove the grounding element from electrical contact with the electrical conductors.

    摘要: An electrostatic discharge protection device is disclosed which automatically connects selected connector pins of a semiconductor chip package ("SCP") or connectors on printed circuit boards such that the connector pins are held at a common voltage until insertion of the SCP into a receptor or until insertion of a cable into the connector which overcomes an internal resilient bias of the electrostatic discharge protection device causing the common connection to be removed. Removal of the SCP from the receptor or the cable from its connector removes the force which overcomes the bias, thereby reestablishing the common electrical connection thus automatically moving the electrostatic discharge protection device between inoperative and operative positions.

    摘要: In a laser light pump, a multiplicity of micromanipulators adjust the positions of a cylindrical lens and line of optical fiber ends relative to each other and relative to a light source composed of a line of laser diode facets. Each micromanipulator achieves extremely fine resolution by imposing a vernier or differential screw arrangement into a flexure ratio divider, and thereby multiplying its resolving capability. The vernier screw arrangement spreads two members of different stiffnesses, and the stiffer one of the members moves the lens or the line of fiber ends.

    摘要: A processing apparatus is provided for immersion treating a photograhic film unit with a low viscosity processing liquid. The apparatus comprises a flexible bag-like liquid container having a film unit receiving section and a communicating liquid reservoir section, and a device for manipulating the container to selectively change the configuration of the container and the distribution of liquid therein. The device includes a pivoting frame which moves components of the receiving section between an open position for facilitating film insertion and withdrawal and a closed position defining the receiving section which is flooded with liquid from the reservoir section to treat a film unit therein.

    摘要: An electrostatic discharge protection device is disclosed for use with a semiconductor chip package where the electrostatic discharge protection device establishes electrical connection between connector pins on the semiconductor chip package and ground, thereby creating a short circuit to protect the semiconductor chip package from electrostatic discharge. The electrostatic discharge protection device is manually operable to engage or disengage a ground connection while remaining attached to the semiconductor chip package. The electrostatic discharge protection device is also removable from the semiconductor chip package either prior to or subsequent to mating a semiconductor chip package with a printed circuit board or other receptacle.

    摘要: An electrostatic discharge protection device is provided for use with a magnetic read/write transducer. The electrostatic discharge protection device electrically interconnects the conductive elements of magnetoresistive (MR) and inductive heads to provide a low-resistance conductive path placing the conductive elements at a substantially equal electrical potential, thus minimizing electrostatic discharge. The electrostatic discharge protection device provides an electrical path between the conductive elements which is manually or automatically removable upon connection to a mating element. The electrostatic protection device has a resilient inward bias to connect electrically conductive elements such that a ground is established between them and is removed automatically upon insertion of the conductive elements into a mating receptacle which is interposed between the conductive elements and the electrostatic discharge protection device.

    摘要: An electrostatic discharge protection device that fits within a connector for high frequency cables having a tubular ground conductor surrounding one or more core conductors. The electrostatic discharge protection device creates a shunt across the one or more core conductors and the ground conductor thus electrically grounding any electrostatic discharge on the one or more core conductors. Upon joining of a complimentary receptor to the connector, the electrostatic discharge protection device automatically withdraws the shunt reestablishing electrical isolation among the one or more core conductors and the ground conductor.
