A curved lead provides a mechanical and electrical connection between a board contact on a circuit board and a chip contact associated with a circuit chip. The chip can be mounted to the circuit board, to a chip carrier or to a multiple-chip module. The curved lead is substantially entirely plated with solder and is formed of a single piece of conductive material. The curved lead has a first surf ace for connection to the chip contact and a second surface, generally parallel to the first surface...

An axially compliant tool assembly for a programmable position controller is disclosed. Various construction details have been developed which provide a responsive means to make the tool axially compliant to deviations between the programmed path of the tool and the surface being worked upon by the tool. In one particular embodiment, the axially compliant means includes a base, a sleeve axially movable relative to the base, a tool disposed on an internally splined shaft, and a radial bearing dis...

A duplex fusing system has a pressure roller which includes a compliant surface which evenly distributes contact pressures to reduce displacement of a previously fused image. The compliant layer conforms to the surface of a substrate sheet and toner on that surface, thereby ensuring that the toner does not migrate when the toner is reheated to a liquid state.

In a hermetic compressor, a seal extending between a suction port and a second port in fluid communication with an internal chamber disposed adjacent an electric motor. The seal includes a cylindrical tubular member, one end of which slidingly fits within the suction port. A slotted conical flange on the other end of the tubular member fits around the port on the chamber. When a suction line is attached to the suction port with a threaded nut and fitting, it abuts against the projecting end of t...

The present invention is a pressure sensing and measurement device that eliminates errors due to compliance and lack of sensitivity. The cell uses a pressure receiving means (such as a flexible diaphragm) to detect an impinging object, a means to counteract the pressure caused by the impinging object (such as internal hydraulic pressure), and a detector to measure the amount of internal pressure used to counteract the impinging force. Since the cell is internally pressurized to a point equal to ...

A resilient compliant hydrodynamic fluid film thrust bearing includes a top bearing sheet of thin metalic foil material, and a lower supporting sheet of the same or slightly heavier gauge material. The top bearing sheet is stamped to produce an annular array of truncated sector-shaped flaps attached to the array along one radially extending edge. The second section is stamped to produce an annular pattern of raised projections formed by bending the material along slits to form radially extending...

A compliant assembly system device including operator means for holding parts to be assembled; first and second interconnected deformable structures for supporting the operator means; the first deformable structure including a deformable portion having a first center being responsive to a force and to a moment applied to the operator means to permit rotation of the operator means about the first center; the second deformable structure including a deformable portion having a second center spaced ...

A printed circuit board package for high density packaging of electronic circuit components is disclosed. The circuit components are cooled by a liquid cooled, cold plate with a compliant mat interface. The interface is made of a heat conductive, electrically insulative compliant structure, such that uniform contact can be made with the circuit components, even if there are differences in the relative heights and shapes of the components.

A pressure dome in which the wall forming the cavity containing fluid under a pressure that is to be measured has such a low compliance as to prevent expansion or contraction of the base of the dome resulting from changes in its temperature from causing the diaphragm of a transducer coupled thereto from buckling.

A compliant electrical connector has a pin with edges to grip the boundary of a hole, the pin having at least one groove sunk in the side thereof so that the pin forms a flexure that flexes to reduce the cross sectional area of the groove as the pin is inserted into the hole.
