Abstract: A socket for carrying an integrated circuit (IC) chip. The socket includes a plurality of opposed contacts which have upper and lower integral beams. The socket also includes a spring-biased movable top with inclined inner side walls to urge the contacts into a latched position with the upper beam contacting a lead or a pod on the IC to establish electrical contact. As the top is pushed down, the resilient nature of the contacts allows the lower beam to ride up the inclined side wall into an unlatched position wherein the IC may be removed from the socket.

Abstract: An IC carrier socket having a top with integrally molded guide pins for initially engaging and maintaining an IC carrier in the proper orientation and position during seating the carrier within the socket.

Abstract: A chip carrier socket which includes conductive contacts each having an outwardly extending upwardly directed cantilevered projection which engages a moveable top forming a part of the socket. The top, when moved downwardly, relative to the base of the socket which carries the contacts forces the contacts outwardly to allow the insertion or removal of the chip carrier. The top includes a multiple-angled camming surface which engages the upwardly extending cantilevered projection of each contact to apply a more generally even force against the contact during depression or downward movement of the top.

Abstract: A hydraulic brake booster includes a housing defining a pressure chamber and an inlet port communicating pressurized fluid to an accumulator and the pressure chamber. The housing includes a bore which slidably receives a charging valve and sealingly receives a check valve. The charging valve sealingly engages the housing bore via a sealing ring in one position and is pressure responsive to move toward a second position abutting the check valve to open communication between the inlet port and the accumulator. A stem is slidably carried in a passage in the check valve and the stem is received in a slot in the charging valve. An operator actuator is engageable with the stem to unseat one end of the stem from the check valve so that pressurized fluid from the accumulator is communicated to the pressure chamber.

Abstract: The present invention relates to a method of constructing a valve. The valve comprises a casing with a bore therein for receiving a valve member. The bore also receives a plug which is engageable with the valve member to control communication through an opening on the plug. The method comprises the steps of inserting the valve member in the bore, connecting the plug with the casing such that the valve member is engageable with the plug and welding the plug to the casing while at the same time embedding the valve member into the plug to provide a valve seat on the plug. In particular, the casing and plug are a thermoplastic material, such as Nylon, and the valve member is metallic so that ultrasonic welding softens the plastic to bind the casing to the plug and to deform the plug by engaging the valve member with the softened plug.
