Abstract: A pivot assembly formed by driving an oversized pivot shaft through first and second self-lubricating flanged bushings. The bushing in the static part of the assembly has a smaller inside diameter than the bushing in the rotating part. Installation of the shaft removes a substantial portion of the wear layer on the first bushing so as to form a tight, non-rotating fit therewith, and a lesser portion of the wear layer on the second bushing so as to form a tight, rotating fit therewith.

Abstract: A machine and method are provided for manufacturing corner posts for protecting products loaded onto pallets, and to provide structural support to permit loaded pallets to be stacked one upon another. The machine includes a continuously moving conveyor which moves a pair of boards from a pick-up station, through a fastening station and to a drop-off station. The boards are stapled or nailed together on the fly by a pneumatic gun which is periodically activated to install a series of staples or nails into the overlapped boards. A hopper holds the individual boards and drops them onto an inverted V-shaped support track through which the conveyor moves. The boards are ramped into overlapping engagement with one another and then stapled or nailed together as they move continuously along the support track.

Abstract: A magnetic transducer is batch fabricated from a pair of confronting elongate composite block substrates each formed of a thin cap of non-magnetic material bonded to a much larger block of magnetic material, such as ferrite. An intermediate winding groove is formed in proximate relation to the non-magnetic material along the length of one or both composite block substrates. One (or both) of the substrates is provided with a plurality of parallel spaced V-shaped grooves oriented in a direction perpendicular to the winding groove, wherein adjacent grooves form therebetween track width defining lands. A core layer of high permeability magnetic material, such as Alfesil material, is deposited over the edges whereby magnetic poles are formed of the edges. A gap layer of insulating material is deposited on the edges over the high permeability magnetic material. Two of the composite block substrates are placed with the edges in aligned abutting relation and are assembled by glass bonding.

Abstract: An improved method for retaining a separable bearing race to a inner bearing member and also preventing twisting of the separable race on the spindle. The circular corner edge where the cylindrical inner surface of the separable race would otherwise intersect with the annular, axial face of the race is machined off with a chamfer that is eccentric to the co axis of the race and spindle. Then, a deformable lip of the spindle is deformed in and over the face of the race, concurrently filling in the eccentric chamfer. When the race thereafter attempts to turn on the spindle, a wedging action is created by the eccentric chamfer to prevent twisting.

Abstract: What is disclosed is a electrical cable connector to shield against EMI, ESD and EMC emissions. The cable connector is used to connect an electrical cable to a mating connector having an integral connecting mechanism such as a threaded exterior surface. The cable has a cable jacket surrounding a braid which surrounds at least one signal lead. The cable jacket is removed over a portion of the cable to expose the braid. The exposed braid is then folded back over the cable jacket to create a braid surface. A coupling ring, which has an integral coupling mechanism such as a threaded interior surface, is placed over the end of the cable. A shield is placed in the coupling ring and a portion of the shield is crimped over the braid surface. An optional wave spring may be placed between the coupling ring and the shield. An insulating insert is placed between the end of the one cable and the mating connector. The coupling ring is screwed onto the mating connector.

Abstract: An electrical connector is disclosed, designed for use with a telephone headset. The connector utilizes angled contacts for low insertion force, resulting in easier mating and longer life. The connector is provided with a latch that allows the connector to be uncoupled with a force roughly eight times the insertion force. Both halves of the connector have beveled edges on the upper surfaces only, allowing the connector to be aligned by tactile feel rather than visual inspection or by trial and error. Fine wires can be terminated on the connector contacts because the wires are accurately centered over insulation piercing points on the electrical contacts, and expansion of the wires in all directions is restricted as the piercing points penetrate the wire.

Abstract: A lower shield has an area smaller than an upper shield. A lead is constituted of a thin lead portion and a thick lead portion, the thin lead portion being formed in a reproduction gap between the upper and lower magnetic shield layers and the thick lead portion being formed spaced apart from the end of the lower magnetic shield layer in the depth direction and extending downward in the thickness direction at a level lower than the thin lead portion. The upper surface of the lead is not formed with a step. The thin and thick lead portions are connected via a contact hole formed through a lower reproduction gap layer.

Abstract: One driver having external electrodes arranged over both surfaces of a piezoelectric ceramic plate polarized in the direction of its thickness, and one generator having two mutually opposed interdigital electrodes on one or both surfaces of a piezoelectric ceramic plate and alternately polarized in the direction of its length between the electrode fingers of the interdigital electrodes are formed combined in alignment in the direction of the length of the piezoelectric ceramic plate. Alternatively, the driver and generator may be formed in alignment in the direction of the width of piezoelectric ceramic plate. By applying a low voltage to this piezoelectric ceramic transformer from the driver at a resonance frequency of a longitudinal vibration of second order mode of the piezoelectric ceramic plate, a high voltage can be picked up from the generator.

Abstract: A vibrator is formed on a silicon substrate to become a base by the silicon-processing procedure and a thin film of a piezoelectric material is formed on the substrate by a method matching with the silicon-processing procedure. When an ac field of a frequency near the resonance frequency of the transverse vibration of the vibrator is applied to the thin film of the piezoelectric material, the piezoelectric reverse effect excites characteristic vibration in the vibrator. If a rotational motion is generated along the axis of the beam in that state, the Coriolis' force is generated in a direction perpendicular to both the axial direction and the vibration direction of the beam. This force deforms the beam in that direction. Detecting inductive charges produced in another piezoelectric thin film fixed on the vibrator because of the piezoelectric normal effect due to the deformation, the rotational, angular velocity can be obtained.

Abstract: A tool 2 used to position a socket 100 on a printed circuit board 200 includes an insertion head 10 and an inertial impact mechanism. A socket, such as SIMM socket 100, is mounted on the insertion head with the lower surface of arms 14 on the insertion head conforming to the upper surface of the socket. A shaft 42 connects the insertion head to the inertial impact mechanism and the shaft is positioned in alignment with a mechanical retention post 110 on the socket. The impact delivered by the tool pushes the retention post 110 into an interference fit with a corresponding hole 204 on the printed circuit board. The insertion head arms 14 includes a rib 34 that overlaps contact terminals 130 in the socket to prevent the terminals 130 from being forced out of the socket when the socket is secured to the printed circuit board. The inertial impact mechanism includes a spring loaded hammer mass 48 of the type used for a center punch.

Abstract: A contact array includes: (1) a plurality of uniform columns each for providing electrical continuity between things respectively in contact with opposite ends of the columns, each column means having a memory urging it to be straight, and (2) an elastomeric carrier, reinforced with a polymer, to which all the columns are affixed, for holding them parallel to each other, spaced apart, aligned along an axis normal to them, and preferably symmetrical with respect to the axis. The carrier also forces the columns to be uniformly arcuate along the axis. The opposite ends of the columns define respective opposite contact margins of the array. A housing defines a chamber for containing the array. Two opposite walls of the chamber define respective openings through which the contact margins protrude for accepting compressive contact forces that are applied during operation.
