Title: Method of making amorphous semiconductor alloys and devices using microwave energy
Inventor: STANFORD R OVSHINSKY
IPC: C23C16/48
Filed: 1983-09-21
Granted: 1987-10-30
Abstract: @ A process for making amorphous semiconductor alloy films (22) and devices at high deposition rates utilizes microwave energy to form a deposition plasma. The process includes the steps of providing a source of microwave energy (17), coupling the microwave energy into a substantially enclosed reaction vessel (12) containing the substrate (14) onto which the amorphous semiconductor film (22) is to be deposited, and introducing into the vessel (12) reaction gases including at least one semiconductor containing compound. The microwave energy and the reaction gases form a glow discharge plasma within the vessel (12) to deposit an amorphous semiconductor film (22) from the reaction gases onto the substrate (14). The reaction gases, for example, can include silane (SiH<sub>4</sub>). silicon tetrafluoride (SiF<sub>4</sub>), germane, or germanium tetrafluoride (GeF<sub>4</sub>). To all of the foregoing, hydrogen (H<sub>2</sub>) can also be added. Dopants can also be added to the reaction gases to form p-type or n-type alloy films. Also, band gap increasing elements can be added to widen the band gap of the alloys.

[Class 108(ii)]  In a vehicle suspension system of the type in which the wheel is supported by one or more articulated transverse links, one link is formed of two angularly disposed rigidly interconnected arms, one of which serves as a torsional spring and is disposed obliquely to the longitudinal axis of the vehicle. and may be arranged to swing about an axis which is out. of parallel with the pivoted axis of the other arm. Fig. 1 shows in plan and Fig. 2 in front elevation a steering wheel suspension in the wheel'carrier 4 is mounted by ball joints on an upper link 6 and lower link 11. both articulated to the frame cross member 2. The lower link 11 has rigidly secured thereto ;one end of a torsion bar 16, whose, rear end is rigidly attached to an anchor member 18 carried by a rubber bush 32 and ball and socket 35. Deflections of the wheel take place about the axis A joining the articulation 47 of the lower link 11 and'the junction of the torsion bar 16 and anchor member 18, and cause, twisting of the torsion bar. A stabilizing bar 38 may be connected to the fronts of the lower links 11, and each lower link may have the arm 39 of a shock absorber 10 connected thereto. The shock absorber 10 is mounted on an extension of the frame cross member 2, which also carries rubber buffers 42, 43 for limiting movement of the links. The lower link 11 is  arranged nearer to the wheel axis than the upper link 6 whereby the major part of any longitudinal thrust on the wheel is taken by the lower link and the torsion bar 16. Theend of the torsion bar may be adjustably mounted in the link 11, as shown in Fig. 4, the splined end of the tor-  sion bar 16 being secured to a plate 20  which can be rotated slightly by adjustable screws 26, 27.

Abstract: 1,213,584. Electric motors having brakes. MOTEURS LEROY. 4 Jan., 1968 [18 Jan., 1967], No. 660/68. Heading H2A. In a motor having a spring-loaded brake plate 15 slidable on the rotor shaft 11 and which, on energization of the motor, is withdrawn from engagement with a stationary friction lining 14 by stator flux diverted through an end ring 22 on the rotor, the ring 22 splits the flux so that 80 to 90% of the flux passes through a series of short-circuited windings W and is displaced in phase relative to the remainder whereby the hole ring is not demagnetized as the flux passes through zero and chattering of the plate 15 is prevented, particularly with a single phase supply. As shown, ring.22 forms part of a squirrel cage rotor 12 and initially has radial slots and annular grooves on opposite faces. Non-magnetic metal such as aluminium, is injected into said slots and grooves and into the rotor slots to form the squirrel cage bars 41, Fig. 7, end rings 42, 43, an outer end ring 46 of smaller diameter, and radial partitions 45.

Figs. 3 and 4 show a machine embodying the above principle, and comprising a support 1 mounted on the axis 8 and having slidable thereon a slide 2 movable by a lever 3 and an adjustable spring 5, a stop 6 being provided to set the initial position of the slide. On the slide is pivoted, about the axis 23, a sector 9 carrying a guide 11x for an adjustable slide 12, perpendicular to the guide 11x, the slide 12 having slidable therein a member 13 carrying the diamond 14. In the member 13 is a slot 15 in which is adjustable the pivot 16 of a link 17, the other end of which is pivoted at 18, the position of the pivot 18 being adjustable by members 19, 20 operated by screws 21, 22 ; an adjustable stop 11 fixes the initial position of the sector 9. In operation, the sector 9 is swung about its pivot by a handle 10, the diamond thereby being moved over the shaped face c of the grinding-wheel M. The apparatus may be mounted on the work carriage of a gear grinding machine. Movement of the slide 2 enables a straight portion to be produced in the wheel profile for grinding straight root flanks on the gear teeth.

Title: Improvements in or relating to pulse-amplitude discriminating circuits
Inventor: COOKE-YARBOROUGH EDMUND HARRY
IPC: H03K17/62
Filed: 1948-01-09
Abstract: 659,825. Pulse discriminating circuits; non- linear valve circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 9, 1948, No. 724. [Class 40 (vi)] An amplitude-discriminating circuit comprises a group of amplifiers of graded backbias all fed from a common pre-amplifier with negative feed-back connections between the amplifiers and the pre-amplifier which produces a stepped overload characteristic in the preamplifier ; in this way the voltage levels at which the amplifiers become successively excited are rendered more constant. The Figure shows a circuit for segregating input pulses applied to terminal 1 into six groups according to their amplitudes the pulses of each group then being further segregated by an amplitude'discriminating circuit as described in Specifications 659,819 and 659,862. The preamplifier comprises valves 2 and 3 connected as a high-gain cathode coupled pair, so that positive input pulses at 1 appear as amplified positive pulses at the anode of valve 3 and are applied to amplifiers 16-21, each of which is normally non-conductive and has a graded back-bias derived from the resistor network 7-13. As the amplitude of the input pulse at 1 increases each valve 16-21 becomes conductive in turn and its anode potential falls linearly the negative feed-back from its anode circuit to the grid circuit of valve 2 via resistors 35-40 reducing the effective gain of the preamplifier until the main amplifier valve saturates. Conductivity is then transferred to the next succeeding main amplifier valve the anode potential of which falls linearly until this valve is saturated. The negative feed-back thus produces a stepped gain characteristic in the pre-amplifier so that at successive boundary levels the pre-amplifier gain is high and a rapidly changing voltage is applied to the main amplifying valves. With an input pulse of given amplitude one only of the amplifiers 16-21 will show an output voltage other than either the potential at point 14 as clamped by diodes 41-46 or the anode potential at which valves 16-21 bottom.
