Abstract: A method for coating tin on a electro-conductive substrate in a bath comprising stannous ions, a mineral acid and a surface active agent alone or in combination with a water soluble acrylate and an aromatic aldehyde or ketone. A catalyst metal comprising metallic zinc or zinc alloy and the substrate to be coated are immersed in the bath. During this immersion electro-conductive contact is effected between the substrate and zinc or zinc alloy. A smooth, pore-free, pure tin coat is deposited on the substrate during the time the substrate is in electro-conductive contact with the zinc or zinc alloy.

Abstract: A thick resin film is formed on the joint part of a welded metallic can body by first coating the joint part with a primer composed of a solution of a thermosetting resin in an organic solvent and drying it, and then coating the dried primer layer with a slurry paint composed of a dispersion of a thermoplastic resin powder in a poor solvent, and drying the coating. The resin powder has a specific gravity differing from that of the poor solvent by not more than 0.2.

Abstract: A peripheral-controller is used to manage data transfers between peripheral units of the magnetic tape type. A program sequencer in the peripheral-controller can signal an automatic read-write selection logic and control unit to operate in the "automatic read" mode whereby an automatic read-logic unit will transfer data out of the magnetic tape peripheral unit into a buffer memory of the peripheral-controller on a continuous basis without further instructions being required from the program sequencer.

Abstract: The invention employs an execution control unit consisting of a look up memory, three instruction registers and logic gates to control pipe line processing by an ALU. During such processing the sequential steps required to execute a program instruction are overlapped so that the ALU and its associated memory are always busy. The three instruction registers are provided to receive and retain up to three instructions which may be in process at a given time. The memory is preferably divided into a plurality of banks to improve the performance of the system by reducing the occurrence of a memory busy condition. To facilitate pipe lining an instruction format is employed having a fixed location for the data field which specifies the register to be used for address preparation.

Abstract: The apparatus comprises an endless tunnel having a wall provided with openings giving access to processing chambers in a locked chamber which has a panel sealing the apparatus from the external environment. A conveyor which follows a closed path is arranged in the tunnel and is provided with seats for containers with articles to be processed and transport means for introducing articles carried by the conveyor into positions opposite to a chamber into a respective chamber. The apparatus has structure by which the environments in the tunnel and in each of the chambers can be controlled. The chambers can each be sealed from the tunnel in a vacuum-tight manner. By means of this apparatus articles, which are screened from the surroundings in a vacuum-tight manner, can be subjected in a controlled environment to a variety of processing steps.

Non-contacting gas seals (3,4) at the top and bottom of the reaction chamber are so constructed that fibre vibration is avoided, (6) surface flaws are minimized and the coating minimizes stress corrosion.

Abstract: A method of manufacturing a mask for use in x-ray photolithography includes the steps of coating a set of wafers (20) with boron nitride (22). The tension in the boron nitride is measured by using a capacitive probe (26) to measure bowing in a set of test wafers. The remaining wafers are attached to a pyrex ring (28), and the boron nitride is removed from one side of the wafers. A circular hole is then eteched in the wafer, and a layer of tantalum (32) and gold (34) are formed on the remaining boron nitride membrane. The gold (34) is patterned via a sputter etching process. Power is reduced at the end of the sputter etching process slowly to reduce mechanical stress in the mask. The tantalum (32) is then etched via a reactive ion etching process. In this way, an x-ray transparent boron nitride membrane is used to support x-ray opaque gold.

The interface between both of the molten baths is kept at least in the area of the refractory wall.

Abstract: A method of controlling light transmission through a reflective/transmissive surface by first creating surface irregularities having an anti-glare effect and then applying an inert liquid coating sufficiently thick to remove at least some, but not all, of the anti-glare effect. The surface irregularities are created by applying a dispersion and allowing it to dry to form a coating that reduces reflected glare at the surface. The dispersion is a dispersion of polyvinyl acetate particulates and water or acrylic particulates and water; alternatively, the dispersion comprises a matte varnish comprising an aqueous dispersion of an acrylic resin, and an aqueous dispersion of polyvinyl acetate.

Abstract: Data from a patch memory (23) is substituted for that in a system ROM (9) by applying high order addresses to a standard PLA (19) having word lines (FIG. 3, 50a-50p). The address orders are separately applied to EXCLUSIVE OR circuits (27a-27g). The PLA (19) is personalized to activate line (21) at addresses to be substituted and to provide logical zeros to the EXCLUSIVE OR circuits (27a-27g) which change during the patch. Only one word line is required for each continuous patch, which vary in size on a patch-by-patch basis. The circuit is fast and efficient. It can be used for a wide variety of memory substitution applications.

Abstract: A thin film transistor array for a liquid crystal display device is produced by simultaneously forming gate electrodes and picture element electrodes; forming islands of a layered structure comprised of a gate insulating film, a thin semiconductor film and a light shielding film in a single masking step; and forming the gate, source and drain wiring metals in contact windows by the "lift-off" technique after using a resist film for opening the contact windows. Only three masking steps are required thereby enabling an increase in production yield and a lower production cost as compared to conventional techniques which typically require seven masking steps.
