Abstract: The present invention provides a contactor assembly (100,200,300) for testing of semiconductor devices (DUT). The contactor assembly (100,200,300) includes a plurality of probes (20,22,24), a contactor holder (150,350) and a cover (180,280) shaped and dimensioned to fit on the contactor holder (150,350). The contactor holder (150,350) is a stack of laminates. A top laminate (156,256) of the contactor holder (150,350) has apertures (158,258). A contact probe (22) is seen through one aperture (158,258). On a rear face of the cover (180,280), there is at least one conductive pad (186) in register with an aperture (158,258). Each aperture (158,258) is operable to house a surface-mount electric component (160), such as a resistor, capacitor or inductor, and a conductive compressive element (162). In another embodiment, a front side of a cover (280) has a connector (285) in electrical communication with a conductive pad (186).

Abstract: An improved clamping mechanism for clamping a dock support frame having a hollow recess and a U-shaped cut-out to a vertical support member has an anvil clamping member comprised of extruded aluminum. The anvil clamping member has an arc-shaped clamping surface and is fixedly disposed inside the hollow recess in the support frame. A hammer clamping member comprised of extruded aluminum and having a corresponding arc-shaped clamping surface is adjustably attached to the anvil clamping member such that the vertical support member can pass between the hammer clamping member and the anvil clamping member and through the U-shaped cut-out of the support frame.

Abstract: A device for providing electrical contact comprises a first reciprocating conductive body having a first abutting body at one end, a second reciprocating conductive body having a second abutting body at one end and a resilient means biasing the first reciprocating conductive body and the second reciprocating conductive body in opposing directions axially away from each other. The first abutting body is slidably abutting the second abutting body, thereby providing electrical conductivity between the first reciprocating conductive body and the second reciprocating body. In another embodiment, the first reciprocating conductive body, the second reciprocating body and at least one securing means are disposed within one of plurality of through holes of an elastic non-conductive housing body. The elastic non-conductive housing body biases the first reciprocating conductive body and the second reciprocating conductive body in opposing directions axially from each other.

Abstract: For swingably mounting a door on a jamb, a dual action self closing hinge has a stationary component which seals, shields, and carries a stationary cam and a rotatable cam follower. The cam elements cooperate with one another to displace the cam follower and attached door panel upwardly during an opening movement and permit the automatic downward movement of the cam follower and door panel upon release of the door panel from an open position. Simultaneous with the cam action, an offset hinge mechanism elevates the center of gravity of the door panel during opening, and likewise provides for the automatic return of the door panel to the closed position to improve the self-closing action of the door. In addition, a cam angular position lock enables the closed position of the door relative to the jamb to be easily adjusted.

Abstract: A two way, double action insulating door is described having an insulating core to which is mounted a pair of structural panels. An extruded edge rail is mounted to each edge margin of the core and retains a peripherally-projecting rubber leaf gasket. Preferably the gasket is of a T-shaped cross section and is retained within a slotted edging mounted to the periphery of the door. The door is provided with durable panels covering its exterior faces and also overlaying portions of the edge rail at the edge margins of the door. Optional window assemblies and kick panels are also provided.

Abstract: A door suspension system has a frame mounting element and a cover element. These elements have projecting clamping elements which cooperate to clamp door strips between them to suspend the strips in a door opening. In addition, one of the cover or frame mounting elements includes a mechanism for supporting pins or other supports from which apertured door strips may be hung. Also, the cover and frame mounting elements may define channels from which door suspension strips may be hung. The combined clamping action and pin support or hanging support of the door strips results in securely supported strips. The cover element and frame mounting element cooperatively engage one another for mounting purposes. In a specifically illustrated embodiment, a set of flanges is provided on the mounting element for mating with a corresponding set of flanges on the cover element for purposes of aligning these elements as they are coupled together.

Abstract: A gravity swing door hinge includes flange guards for protecting the hinge from damage and a telescopic cover assembly for protecting the cam and eliminating pinch points between cam parts and between the door and the hinge body. The hinge may be flush mounted to a door jamb while providing a broad range of pivotal movement on each side of its closed position.
