IPC: H01L49/02
Abstract: 1,095,413. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 8, 1965 [Dec. 24, 1964], No. 47223/65. Heading H1K. Parts of a layer of semi-conductor material forming components of an integrated circuit are isolated by etching deep grooves between them and filling the grooves with insulating material. An N-type silicon substrate 1a has a P-type epitaxial layer 1b deposited on one surface by thermal decomposition of silicon tetrachloride using hydrogen as a carrier gas. The surface of layer 1b is covered with a photo-resist which is exposed and developed, Fig. 2A (not shown). The wafer is then etched using a mixture of nitric, hydrofluoric and acetic acids to expose the substrate, Fig. 2B (not shown). The surface is masked using a thermally grown oxide layer and phosphorus is diffused-in to form highly conductive connection regions (5) extending across the floors of etched grooves (B) and up the sides of the islands (R), Fig. 2D (not shown). The oxide mask is removed and the device anodized, using sulphuric acid and a platinum cathode, to form a thick layer (7) of silicon dioxide which at least fills grooves (B), Fig. 2E (not shown). The surface of oxide layer (7) is masked with a photo-resist (25) Fig. 2F (not shown), and is etched to expose the surfaces of the islands (R), Fig. 2G (not shown), to provide a reference level. The surface of the wafer is lapped to this reference level and chemically polished using sodium hydroxide, Fig. 2E (not shown). An oxide layer 9 is then formed on the surface of the wafer and transistors are formed by diffusion in selected islands A, Fig. 1C. Interconnections are formed by vapour depositing strips 13 of aluminium or molybdenum over the oxide layer, crossovers being effected by contacting the ends of diffused connection regions 5 and depositing the crossing connections on top of oxide layer 7 at right angles to region 5. The arrangement of an AND-INVERT gate is illustrated, Figs. 1A and 1D (not shown), in which four transistors (T1 to T4) are formed in islands (A), while the diffused connection regions (5) extend between smaller islands (C) on which connections are made between deposited conductors and regions (5). Thin film resistors (3, 3<SP>1</SP>) are deposited on top of oxide layer (7) and extend at right angles to the direction of regions (5).

An air cushion vehicle 2 for operation over a fixed track 1 is supported by cushions in plenum chambers 4 enclosed by flexible skirts 8 and guided by cushions in plenum chamber 5 enclosed also by flexible skirts. The free edges of the skirts are arranged in close proximity to the track surfaces to reduce power losses which would otherwise result from large air gaps. This results in more frequent contact between said free edges and the track and consequential wear of the skirt, and to reduce such wear each skirt is formed with hollow ducts 13 or has duets attached to its outer surface, from which a non-gaseous flowable lubricant is discharged from apertures in the lower face edges. An alternative means for providing lubricant directly to the track comprises a wheeled carriage (Fig. 15, not shown) associated with the track, the carriage carrying a tank for lubricant and a pump and ducting arranged to discharge lubricant directly on to the track in way of the flexible skirts.

Abstract: 1,266,513. Magnetic core storage. ELECTRONIC MEMORIES Inc. 19 May, 1969, No. 25509/69. Heading G4C. A magnetic core matrix is modified whereby a plurality of planar arrays can be accessed simultaneously. Previously each array was written into or read from individually, hence the quantity of switching and selecting hardware is reduced. Prior Art (Fig. 1, not shown).-This is a so- - called 2“ D high-speed memory system having a number of planar arrays each accessed separately. Each core in an array is accessed using coincident X,Y enabling pulses. The Apparatus.-An array comprises a number of core planes 1 arranged in one plane, and the X and sensing lines for each column of each core plane are energized separately as before. A Y winding passes through each row of cores in an array and is connected to a common bus. In this embodiment there are 4 arrays disposed in a square, the busses of adjacent planes in the square being connected together. One end of each bus is connected to a sink switch and the other ends of each Y winding is connected to a junction between two diodes O, the other ends of the diodes being connected through respective transistors which act as drive or current switches and are connected to a current source. Writing.-One sink switch is energized to allow a current flow in one direction, another sink switch is energized to allow current flow in another direction and the two current switches are enabled in each array. Thus current flows through the Y winding of all arrays and selected X lines may be energized to cause writing. Reading.-The direction of current flow through the Y windings is reversed using the sink switches and the selected sensing lines are energized. It is possible to energize only one row winding, two embodiments of current sources are described (Figs. 3 and 4, not shown), and the arrangement may be used for 3D systems.

Abstract: 1295038 Aerosol hair dyeing compositions L'OREAL 4 Feb 1970 [4 Feb 1969] 5282/70 Heading D1B Aerosol containers contain hair dyeing compositions (e.g. oxidation dyes) comprising at least one dye microencapsulated in microcapsules of diameter 50-800 microns, the micro-capsules being suspended in a liquid medium which comprises (a) a liquefied propellant, e.g. butane, trichloro-fluoro-methane, dichloro-difluoro-methane or dichloro-tetrafluoro-ethane and optionally (b) an aqueous solution containing dyeing ingredients not microencapsulated. All the ingredients of the composition may be separately microencapsulated or microencapsulated with other compatible ingredients. The microencapsulating material is a low density polyethylene of melting point 106-109‹C or polyvinyl alcohol. In a preferred embodiment the aerosol container contains a first microcapsule containing a stable oxidising agent, e.g. stabilised hydrogen peroxide, the encapsulating material being permeable to the propellent, and second microcapsule containing dye, the encapsulating material being impermeable to the propellant but soluble in water and a third microcapsule containing a base, e.g. ammonia the encapsulating material being permeable to the propellant. The first and third capsules are caused to burst by excess pressure due to propellant and the second by contact with water. Hence the dyeing composition may be formed inside if water is present or outside the container, e.g. by spraying onto moistened hair. The container used is provided with a pressure reducing valve allowing the pressure to fall to atmospheric without allowing dye to leave the container, this valve also acting as an inlet valve to first pressurize the container and also with an inlet valve for additional propellant to repressurise the container for spraying. The reduction to atmospheric pressure causes the propellant permeable microcapsules to burst.
