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: Disclosed herein is a method of producing a magnetooptical disk by way of depositing a recording layer, a protective layer, and a reflection layer on a transparent substrate. The inventive method features that the refractive index of the protective layer is subjected to a precise control by way of changing the flow rate of argon gas within the range of no greater than 100 SCCM while maintaining the flow rate of nitrogen gas substantially constant at a value within the range of 3 to 10 SCCM.

Abstract: Disclosed herein is a novel process for the manufacture of optical bistable switching device including multiple quantum wells. The process is carried out by: supplying a first organo-metallic compound as the source of a first metallic element and a reaction gas continuously while supplying a second organo-metallic compound as the source of a second metallic element in a discrete mode into a reactor and cultivating a semiconductor multiple quantum wells region having multiple pairs of intrinsic semiconductor-layer/semiconductor-layer(GaAs/AlGaAs), one of the layer containing said second metallic element(Al), while controlling the mole fraction of said second metallic element(Al) to be in the range of 0.01 to 0.25 of the total first and second metal contents existing in the layer containing the second metallic element, thereby lowering the impurity concentration and optimizing the negative resistance.

Abstract: A process for RIM bonding urethane gaskets to glass panels which includes storing a primed glass panel in a temperature-humidity controlled environment for 20-28 hours. The primed and conditioned panels are then fitted with RIM gaskets with 24 hours after removal from the controlled environment.

Abstract: A convertible sofa-bed which includes a bed support frame which is shiftable with respect to the sofa frame to convert the sofa-bed between sofa and bed positions. The bed support frame is attached to one of the arm supports and is extended into a bed position by pulling on the sofa arm. The sofa-bed may also include a unique two-piece bed support frame connected by an over-center pivot linkage which locks the bed support frame into the bed position.

Abstract: Apparatus for continuously recovering oil-only from mature wells with typically low production. The apparatus includes a continuous chain which is suspended in the oil-containing portion of the well. By continuously moving the chain, oil is drawn out of the well and deposited in a collection box.

Abstract: An improved apparatus for automatically measuring the viscosity of a sample liquid is disclosed. The apparatus comprises a plurality of viscosimeter tubes mounted in a constant temperature bath, a plurality of vessels adapted for containing the sample liquid, a valve system for controlling the injection and the removal of the sample liquid into and from the viscosimeter tubes and the ascent and descent of the sample liquid in the viscosimeter tubes, a driving circuitry for the valve system, a photosensing device for sensing the meniscus of the liquid at predetermined indication marks of the viscosimeter tubes and a system of measuring the flow time of the sample liquid between two predetermined marks and computing the viscosity of the liquid based on the measured flow time.

Abstract: An antistatic roll is provided for use in transferring and/or winding a continuous sheet of polymeric film. The roll comprises a cylindrical core made of an electrically conductive material which is provided with a pair of rotational shafts, each extending away from the opposite ends of the roll in an axial direction. A layer of dielectric material surrounds the core, which has a spiral groove formed on the outer circumference thereof at a substantially equal pitch. An elongate conductor is held within and extends along the spiral groove to gather static electricity from the roll and/or the polymeric film. Associated with the elongate conductor is a grounding arrangement to drain off the static electricity gathered therein.

Abstract: An NC lathe includes a bed, a headstock mounted on the bed for rotating a work around C-axis, a tailstock slidably mounted on a first guide surface formed on the bed, and a carriage slidably mounted on a second guide surface formed on the bed in a direction of Z-axis parallel to the C-axis and juxtaposed with the first guide surface. The carriage has a saddle having a first slide surface for contacting the second guide surface of the bed and a second slide surface inclined at a predetermined angle with respect to the first slide surface. A slide base is slidably mounted on the second slide surface of the saddle for movement in a direction of Y-axis perpendicular to the Z-axis. A column extends from the slide base substantially perpendicular thereto and includes a column body which has a guide surface in a direction of X-axis perpendicular to the Z-axis and to the Y-axis. A cross slide is slidably mounted on the guide surface of the column body in the direction of the X-axis and includes a driving device.
