Abstract: An electrical connector configured to nonrigidly apply force to a semiconductor substrate in directions substantially normal to a plane of the semiconductor substrate. The electrical connector includes a first member with an electrically conductive element and a first attractive element and a second member that includes a support element and a second attractive element. Attractive forces, such as magnetic attraction, between the first and second attractive elements secure the first and second members of the electrical connector to the semiconductor substrate in a manner that facilitates communication between the electrically conductive element of the first member and one or more semiconductor devices carried upon the semiconductor substrate. The electrical connector may be used in stress testing of semiconductor devices or to otherwise establish an electrical connection between one or more semiconductor devices, a ground, and a power source.

Abstract: Disclosed is a ball-and-socket joint connection, in particular for a holding arm system for holding surgical instruments, with a joint ball sitting in a seat of a joint casing and permitting rotation in several axes and with a ball-shaped joint socket which can be axially displaced to and from the joint ball in a cylindrical section of the joint casing. A magnet is provided which produces a magnetic force between the joint ball and the joint socket such that they are drawn to one another. An actuation element is provided for displacing the joint socket and with this the joint ball is fixable in the seat of the joint casing by way of retracting the joint socket, wherein the joint ball by way of the magnet force is pressed into the seat of the joint casing, and wherein the joint ball by displacing forwards the joint socket with the actuation element is separable from the seat.

Abstract: The invention provides a card connector with a card discharging mechanism, in which a data storage card does not exit from the card connector due to the biasing force of a spring member, and in which the card can be easily extracted without weakening the biasing force of the spring member. The card connector includes a housing, an eject arm, a slide member, a return spring, a retaining member and an operation restricting mechanism. The data storage card may be attached and detached to and from the housing. The eject arm engages with the card and is rotatable in the card inserting and discharging directions. The slide member, to which the eject arm is mounted, slides in the card inserting and discharging directions. The return spring biases the slide member in the card discharging direction. The retaining member retains the slide member at a card insertion position against the biasing force of the return spring.

Abstract: It is described a grounding terminal for temporary fastening a grounding conductor to a construction to be welded. The grounding terminal uses permanent magnets, example given of neodymium (Nd—Fe—B-35) to fasten the terminal to the construction. A welder that uses the grounding terminal can by one grip easily scrape the contact surface of the construction free of paint, rust and oxide scale and thereafter fasten the grounding terminal to and unfasten it from the construction. Fastening and unfastening is based on relocation of the permanent magnets in such a way that an open and a closed magnetic loop respectively, are created.

Abstract: An electromechanical connecting device can be connected to a switching device provided with switching magnets, arranged on a working carriage and connectable to a current source by means of current supply contacts, and can also be connected to a triggering device provided with triggering magnets and electrically connectable to a consumer. These switching magnets can be moved from a rest position to a working position against a restoring force, establishing a contact among pairs of contacts and thus an electric connection between the means of a special coding together with the triggering magnets arranged in the triggering device to generate particular magnetic fields for the switching process.

Abstract: This unit comprises two independent rectangular prismatic parts, fitted into each other by superposition, the top or head of the unit involving a flap cover articulated on one of its sides, which carries on its top face, a handle for activation and on the lower face, the continuity bridges. The continuity is established among the service and the couple terminals, two by two, in such a manner, that when the cover is rotated during the opening movement it carries said continuity bridges with it, simultaneously emerging from end grooves for insertion of said service and couple terminals, remaining joined to the cover and the latter, to the head of the unit by means of its hinge.

Abstract: A base structure for receiving an electrical relay is described as being adapted to receive the relay removeably. Electrical contacts in the base connect the base electrically with the circuitry of the attached relay. Terminals are provided for the connection of external wiring to the base and are each connected to at least one of the electrical contacts. Permanent magnets affixed to the base attach the base securely to an electrical panel so that the base is easily removed. According to a modification, electro-magnetism is used to secure the base to the panel. A magnetic shield is disposed, according to a modification, between the source of magnetism and the attached relay.
