Title: Method of winding a mos transistor in the surface of a substrate
IPC: H01L29/00
Filed: 1971-07-08
Abstract: 1328018 IGFETS MOTOROLA Inc 8 July 1971 [23 Sept 1970] 32074/71 Heading H1K In a monolithic integrated circuit including an IGFET comprising source and drain diffusions in a substrate of opposite conductivity type formation of surface channels providing a leakage path, e.g. to other components of the circuit, is avoided by disposing around the IGFET a more heavily doped surface layer of the same conductivity type as the substrate formed by diffusion from a doped silica glass layer. In a typical process, after the conventional formation of P type source and drain inclusions in the face of an N Si wafer, the oxide masking is removed and the face covered with 500  of silica and a 10,000  overlayer of phosphorus-doped silica. After etching to reexpose the channel site the wafer is heated for 1¢ hours at 1115 C. to form N+ surface layer 19 (Fig. 4) and pure oxide gate insulation 20. Electrodes are then provided conventionally. In an alternative method the N + layer is formed as above but prior to formation of the source and drain. To form these amorphous silicon is provided over the gate insulation by overall deposition and back etching, apertures formed through it and the underlying gate insulation and acceptor material diffused to form the source and drain beneath the apertures and to dope the amorphous silicon. Contacts are then formed to the drain, source, and amorphous silicon gate in conventional manner to extend over a further oxide passivation layer.

Abstract: 902,851. Lathe and other machine-tool det ils. PROGRE'S INDUSTRIEL JONES & LAMSON MACHINE CO. Oct. 9, 1958 [Feb. 8, 1958], No. 32249/58. Class 83 (3). Speed and fuel control mechanism for lathes and other machine-tools comprises perforated cards enabling plugs to be inserted in a control plug-board to establish pre-determined electric circuits in which switches provided in the path of trip dogs are carried on interchangeable members attached to the slides or like members to be controlled. The longitudinal carriage 2, Fig. 1, of a lathe is fed by an hydraulic ram 4 having a control-valve 9 and a throttling device 26. An interchangeable plate 1 with adjustable dogs 5, 6, arranged according to the workpiece to be produced, is secured to the carriage 1 and operates switches 7, 8, respectively. The lathe spindle 22 is driven by a change-speed device 24 the speeds for which are pre-selected by a plugboard 23. A similar plug-board 17 is provided for pre-selecting the sequence of operations and the parts of the machine tool, e.g. slides, turret, &c., to be utilized. The plugs are set by punched cards 13, 35, placed over the boards. The carriage speeds are controlled by a cam 25 secured to the plate 1. The throttle valve 26 gives maximum speed at the start and as the roller 38 moves up the cam-slopes the speed is reduced. The lever 46 is finally moved to operate a switch 47 for limiting the stroke. One of the dogs 5, 6 operates a reversing device while the other opens a valve 14 for the operation of the next machine member. The arrangement may be applied to a turret lathe in which indexing of the turret 49, Fig. 4, also indexes a cam drum 50 which gives a different combination of feed &c. speeds for the turret carriage for each face of the turret. The plates 1 may be stored with their corresponding punched cards so that a given workpiece can be repeated when required.

[Also in Group XI] In a combustion chamber for the combustion of gaseous fuels of low calorific value in a gas-turbine installation, combustible gas and air are supplied to chambers arranged alternately and circumferentially, the gas and air issuing from the chambers in a peripheral direction and obliquely to the axis of the chamber, each gas and air chamber having a slit-like outlet, the outlets being combined in pairs and deflecting surfaces being mounted adjacent each pair of outlets so as to deflect the air and combustible gas streams in the desired direction. In the apparatus shown, a flame tube 6 having air inlet openings 5 is mounted within an outer casing 1 having an air inlet branch 10 at one side thereof. Combustible gas is supplied through an inlet 20 to an annular channel 19 surrounding alternately and circumferentially arranged combustible gas and air chambers 11, 12, gas entering the chambers 11 through the open radially outer sides thereof. Air enters the chambers 12 through openings 18 in the upstream wall 15 from the space 17 on the upstream side of the chambers. The gas and air chambers are separated by means of wall members 16 and gas and air discharge from the chambers through slot-like openings 22 and 23 respectively, deflectors 24 being disposed adjacent each pair of openings 22, 23 so as to cause the air and gas mixture to flow in a peripheral direction obliquely to the chamber axis. The openings may be interrupted by short connecting pieces or they may be formed as a row of closely-spaced holes. Some of the combustible gas chambers may be closed by means of flaps or slides for regulation of combustion. An auxiliary combustion chamber 8 may be disposed upstream of the gas and air chambers 11, 12 so as to discharge centrally therethrough the chamber 8 comprising a perforated flame tube 27, a liquid fuel injector 25, swirl vanes 26 and a rotary valve 29 controlling the supply of primary air to the chamber. A three-way valve 30 is disposed in the combustible gas supply line whereby air may be supplied from the line 32 to the chambers 11 when liquid fuel only is being burned, the air from the chambers 11, 12 then constituting secondary air.

Abstract: 618,698. Lasts for footwear. INGRAM, A. Nov. 5, 1946, No. 32833. [Classes 17 (i) and 17 (ii)] With a view to retaining the proper relation of the - bones of the foot and leg, especially in high-heeled footwear, a last is employed wherein the length G from the first metatarso-phalangeal joint S to the back of the heel of the shoe at HJ is measured with the foot supported on a horizontal surface which passes under the region of the joints in a fully arched condition and with the heel at a height K for which the foot wear is designed. A plane A-B, Fig. 2, through the back of the heel and the centre of the line 3-3 of the metatarso-phalangeal joints and containing the centre line of the usual upper rear surface of the last is vertical, so that the heel is not tilted either inwardly or outwardly. The upper at the vamp 17 is slightly convex and the sole is convex in cross-section at the ball under the joints and mainly concave transversley at 15, when viewed from inside the shoe, the concavity being, greatest on the outer side and decreasing towards the inner side of the shoe. The heel platform 19 lies in a plane Q-R which passes through the first metatarso-phalangeal joint S, and the net effect of the shoe on the foot is to support it against longitudinal movement in the region of the metatarsophalangeal joints and at the heel and brace it in a position such that the os-calcis lies at substantially the same angle to the ground surface as if the foot were resting flat on the ground. The last may be constructed -as described in Specification 618,943.

Title: Method of increasing the size of the dispersed particles in a synthetic rubber latex
IPC: C08C1/07
Filed: 1959-09-29
Abstract: The size of the dispersed polymer particles in a butadiene-polymer synthetic rubber latex containing 2-10 parts of a water soluble soap of soap-forming monocarboxylic acid per 100 parts latex solids and having a pH from 8 to 11 is increased by reducing the pH of the latex to 5,5 to 7,5 in the presence of 0,01-1% of polyvinyl methyl ether based on the latex solids and then increasing the pH to 8 to 11. Butadiene styrene copolymer is the preferred rubber.  Specified soaps are the alkali-metal, ammonium and amine salts of higher fatty acids of 10 to 24 carbon atoms or of rosin acids including dehydrogenated, hydrogenated and disproportionated rosin acids.  Other surface-active dispersing agents e.g. alkyl sulphonates, alkyl and alkyl aryl sulphonates may also be present.  The pH may be reduced using carbondioxide, formic or acetic acid, sodium silicofluoride, or an ammonium salt of a strong acid together with formaldehyde.  The pH may be increased, e.g. by adding ammonia, or sodium or potassium hydroxide.  The latex may have an initial solids content of 20-50% and finally be concentrated, e.g. by evaporation of water, to 55 to 70%.
