Title: Method for interconnecting layers in a semiconductor device
Inventor: KIM JIN-HONG
IPC: H01L23/522
Filed: 1991-11-20
Abstract: A method for interconnecting layers in a semiconductor device is disclosed. The device includes a lower conductive layer (100) formed by capping a second conductive layer (100b) on a first conductive layer (110a), a contact window formed in an inter-insulating layer (20) on the lower conductive layer (100), and an upper conductive layer (200) connected to the lower conductive layer (100) through the contact window. The contact window is formed by removing a portion of the inter-insulating layer (20) where the contact will be formed using a first etching gas e.g. a fluorine mixture, and removing a portion of the second conductive layer (100b) where the contact will be formed using a second etching gas e.g. a chlorine mixture. The contact resistance becomes uniform by preventing the formation of a non-volatile mixture in the contact window, and the reliability of the device is improved by planarizing the surface of the lower conductive layer (100). <IMAGE>

Patent GB-2263215-A (GB)
Title: Pixellated to vector image conversion
Inventor: GILLESPIE JOHN DAVID
IPC: G06T9/20
Filed: 1992-01-06
Abstract: An electronic imaging system receives a pixellated image and stores it in a store (14). An edge information deriving unit (18) produces data relating to edges in the image and stores this in another store (20). An expander (26) takes the stored edge information and expands it. Each edge in the image is then "double-lined" by a unit (30) prior to sets of co-ordinates representing the edge information being generated and stored in a co-ordinate store (4). A vector fit unit (8) then produces vectors corresponding to edges in the image and these are stored in vector store (10). <IMAGE>

The latter has a first set of flutes 11a1-11a14 fixed on rotor 16 and a second set of flutes 11b1 -11b14 on pivotable levers 22.1-22.14 which can pivot the flutes of the second set away from and back toward the peripheral surface of the second conveyor. One flute of each pair of flutes on the first conveyor 1 delivers a pair of cigarettes directly into a flute of the first set, and the other flute of each pair of flutes on the first conveyor delivers a pair of cigarettes into a flute of the second set. The flute of the second set is then pivoted toward the peripheral surface of the second conveyor 6 and comes to rest between two flutes of the first set. Pivoting of levers is achieved by roller followers 19.1-19.14 on levers 22.1-22.14 extending into a groove of a cam 21. The flutes have suction generating devices. <IMAGE>

Title: A method of processing ferrous materials
Inventor: RUSHE JOHN
IPC: C21C7/00
Filed: 1993-12-21
Abstract: Molten ferrous material (2) is stirred by bubbling a gas therethrough. A refractory ring (10) is first partially immersed in the molten steel within a substantially slag free portion of the surface of the molten ferrous metal to form a bounded substantially slag free area. The molten steel is then heated by the introduction of exothermically reacting heating agents such as aluminium and oxygen through an oxygen gas line (7) and an aluminium delivery tube (9) respectively. The refractory ring (10) is then removed from the molten steel when the steel has reached a predetermined temperature and air is then excluded from the volume above the molten steel by placing a hood (16) over the ladle containing the molten steel. Sulphur is then removed from the steel. <IMAGE>

Title: Photographic processing
Inventor: RIDGWAY MICHAEL
IPC: G03D3/00
Filed: 1994-08-27
Abstract: It is well known to process photographic materials in web and sheet form by passing the material through a photographic processor which comprises a plurality of processing stages, for example, developer, bleach, bleach-fix, wash, and stabiliser stages etc. The material is processed by being substantially immersed in the solution in each of the processing stages. Described herein is a method of photographic processing in which the volumes of processing solution are substantially reduced. An inert atmosphere is provided inside each processing stage, particularly the developing stage, to counteract the deleterious effect of aerial oxidation and evaporation. In particular, if the processing chemistry is inherently unstable, for example, RX chemistry, the temperature and humidity of the inert atmosphere is controlled to prevent uncontrolled developer amplification taking place. This control is carried out by supplying nitrogen from cylinder 110 through chamber 104 where temperature and humidity is adjusted and pumped by pump 106 into processing stage 12, the nitrogen being recycled via conduit 114 to chamber 104. <IMAGE>

Title: A piezo-electric effect vibrating gyrometric device
Inventor: LEGER PIERRE
IPC: G01C19/5677
Filed: 1996-02-13
Abstract: The appts. includes a disc (12) constructed from piezoelectric material and is seated on a base of low expansion which bears thirty-two electrodes on its surface. Exciting electrodes (Em+,Em-), bearing potentials of opposite polarity, are designed to produce a motor field and 4R type vibrations in the disc. Electrodes (Dm+,Dm-) detect the motor field but not any vibrations due to Coriolis acceleration and they are used for regulation.  Electrodes (Dc+,Dc-) detect the Coriolis field which is compensated by further electrodes (Ec+,Ec-). The exciting and compensating electrodes are interleaved with the detecting electrodes but separated from them by guarding electrodes (26) at earth potential. The excitation electrodes provide radial nodes of the fourth order and are dependent on a predetermined source. The source induces radial nodes having a frequency less than the nodes at the tangential node.

Title: Actuator controlled valve
Inventor: LOMAX A J
IPC: F16K37/00
Filed: 1996-02-24
Abstract: A fail-safe valve includes a medium inlet for flow of a fluid which passes into a housing. It is stopped/started by the seating action of a valve stem which moves up and down giving reciprocating movement to engage a mechanical position indicator. The valve stem's upward stroke also closes an adjacent circuit which illuminates an LED and its downward stroke illuminates another LED. The stem is fitted to a piston which is pressure controlled by hydraulic fluid which enters through a hydraulic inlet and exits through a hydraulic outlet. The flow then enters a check valve sub assy in which its spring loaded tip is forced back by the medium fluid which exits out of the medium outlet. The valve is suitable for sub-sea applications and may be made from stainless steel, duplex, super duplex, 6MO or other alloys.
