Abstract: @ A motor vehicle steering knuckle and kingpin assembly having a kingpin (12) fixedly mounted through the motor vehicle front axle or beam (16) with the end portions (32), (36) of the kingpin projecting above and below the front axle or beam. A wheel spindle knuckle (24) is pivotally mounted relative to the kingpin, the spindle knuckle having an upper yoke (26) having a bore (30) disposed around the kingpin upper end portion and lower yoke (28) having a bore (34) disposed around the kingpin lower end portion, a bushing (44) being installed in each of the yoke bores. The kingpin end portions have a frusto-conical peripheral surface and the yoke bushings have a cylindrical internal surface such that, under load, the bearing surfaces in engagement and capable of nransmitting the load are along the whole length of the bearing surfaces (Figures 4-5). Alternatively, the kingpin end portions are provided with a peripheral cylindrical surface co-operating with an appropriate frusto-conical internal surface for the busings (Figures 6-7). The invention also contemplates providing the kingpin end portions with a slightly spherical peripheral surface co-operating with yoke bushings having a cylindrical internal surface (Figures 8-9), or providing the kingpin end portions with a cylindrical peripheral surface co-operating with yoke bushings having an inversely spherical internal surface (Figures 10-11 Preferably, the kingpin end edges have a curved surface (79), (81) progressively blending with the peripheral surface of the kingpin end portions or, in structures where the kingpin end edges project beyond the bushing end edges, the bushing end edges are provided with a curved surface (79), (81) progressively blending with the internal surface of the bushings.

Abstract: The present device comprises, in a preferred embodiment, a permanent magnet assembly which is formed to closely resemble a doughnut with the inside surface defining an aperture having first and second ends. Said inside surface is formed concave to substantially resemble the letter "C." The permanent magnet provides magnetic flux from one end of the "C" shaped inside surface to the other end. Hence the magnetic flux lines, or the magnetic flux field, from an enclosure with the concave configuration of the inside surface. An anode is located within the enclosure and is shielded by the magnetic flux field, i.e., the magnetic flux impedes the electrons from directly striking the anode. A cathode means is fitted over said first end of the aperture of the permanent magnetic assembly. A plasma exit plate, having a substantially large aperture therein, is fitted over said second end of the aperture of the permanent magnetic assembly. A source of electrical voltage (which has a first terminal with a first voltage and a second terminal with a second voltage, said second voltage being negative with respect to said first voltage) has its first and second terminals respectively connected to said anode and said cathode to cause an electrostatic field therebetween. In the preferred embodiment the voltage sources are independently variable. In addition, the present device has a means for uniformly passing ionizable gas into the chamber defined by the position of the magnetic flux, the position of the cathodes and the position of the plasma exit plate. Accordingly when electrical energy is applied to the anode and the cathode, a dense plasma results and a substantial amount of the plasma exists above said substantially large aperture to provide a body of plasma external to the device.

Title: Differential gear drive
Inventor: FRY TIMOTHY SELWYN
IPC: F16H48/20
Filed: 1986-04-07
Abstract: A differential gear drive having two output shafts 10, 13 each coupled through a differential gear train to a common input gear 1. The differential gear train comprises an annulus gear 4 engaging the input gear 1, planet gears 5, 6 and a sun wheel 7. The output shaft 10 is connected to a planet carrier 8 and the output shaft 13 is connected to the sun wheel 7. A pair of cam rings 15 and 16 are rotatably coupled to the respective output shafts 10, 13 and are respectively coupled via clutch teeth 19, 20 to clutch rings 17 and 18 respectively, which are engageable separately with a pair of meshing reference gears 29 and 2. The reference gear 2 is rotatably fixed by a countershaft 3 to the input gear 1. When both output shafts 10, 13 are driving against substantially equal torques the clutch rings 17, 18 are both disengaged from the reference gear 29 and so the drive to each shaft 10, 13 is via the differential gear train. However when one of the output shafts commences to loose resistance torque, the respective clutch ring engages the reference gear 29 and so a reaction via the reference gears is provided for the other output shaft, thereby maintaining traction in the case of a motor vehicle.

Abstract: In a circuit containing integrated MOS transistors and/or bipolar transistors, the load resistors arranged as thin-film strips (14) on the field oxide regions (2) separating the active transistor regions consist of polycrystalline silicon (4) which is produced at the same time as the gate electrodes (24) and/or the emitter or base terminal regions of the bipolar transistors on the substrate (1) containing the integrated circuit. The load resistors (14) are structured by means of an oxide mask (5) which acts as an etching barrier in structuring the gate electrode which consists of a polysilicon (24) double layer and a refractory metal silicide (27). Since only the polysilicon (4) of the gate level (24) is used without the silicide (27) on top of it for the load resistors (14), the sheet resistance of the load resistors (14) can be adjusted independently of that of the gates (24, 27). The invention can be used for CMOS and bipolar CMOS circuits.

Abstract: There are disclosed techniques concerning read­ing out Bloch lines in a Bloch line memory device, where pairs of Bloch lines (4) are used as information carrier. The pairs of Bloch lines (4) are transferred to the head portion of a stripe magnetic domain (2) and an in-plane magnetic field (H c ) is applied at the proximity of the head portion of the stripe magnetic domain so that the pairs of Bloch lines are splitted. In this way only one of the Bloch lines (4-l or 4-2) can exist stably at the head portion of the stripe magnetic domain. Then the Bloch lines (4-l or 4-2) are transformed into a magnetic bubble domain (8) by making electric current to flow through a hair pin shaped conductor (7) disposed at the proximity of the head portion of the stripe magnetic domain (2). This magnetic bubble domain is detected by a magnetic bubble detector.
