Title: Optical switch matrix arrangement
Inventor: O'DONNELL ADRIAN CHARLES
IPC: H04L12/933
Filed: 1992-09-14
Abstract: An optical switch matrix arrangement comprises an array of optical switches, each switch being switchable between N, e.g. 2, states in which a light signal is directed selectively between a first node and any one of N further nodes of the switch. The arrangement further comprises oscillator means for oscillating each switch between the N states, the switches being arranged in ranks in a tree-like configuration with the N further nodes of a first switch in a first rank being each connected to a first node of one of N further switches in a second rank. The oscillator means is arranged to oscillate the switches in the second rank between the N states at a frequency that is 1/N x the frequency with which the switches in the first rank are oscillated. <IMAGE>

Title: Process for enhanced delayed in situ gelation of chromium polyacrylamide gels
Inventor: TACKETT JR JAMES E
IPC: C09K8/512
Filed: 1991-07-02
Abstract: The present invention is a process for selectively plugging high permeability zones of a subterranean hydrocarbon- bearing formation by enhancing the delay associated with the in situ formation of a polymer gel. The process comprises predetermining a gelation delay time based on a formation's temperature, permeability and porosity, the distance from the well bore a region to be plugged is located, and a volumetric rate of gelation fluid injection. A gelation solution is then prepared comprising polyacrylamide a polyvalent metal carboxylate crosslinking agent, a gelation delaying agent and a buffer with a pKa of about 3.5 to about 6.8. Gelation delays are achieved by selecting the polyacrylamide concentration, delaying agent concentration and type, and buffer concentration and type, for given formation conditions. Delay times can range from several hours to several weeks at formation temperatures near 176 DEG F (80 DEG C) and from several hours to about one day at formation temperature above about 219 DEG F (104 DEG C). The prepared solution is then injected into the formation via a well bore and allowed to gel. The gel selectively plugs high permeability zones within a subterranean hydrocarbon- bearing formation, at temperatures and distances from the well formerly unobtainable, resulting in improved vertical or areal conformance of injected fluids and improved oil production.

Patent GB-2265802-A (GB)
Title: Image generator
Inventor: WOOD KARL JOSEPH
IPC: G06T15/00
Filed: 1993-06-04
Abstract: An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels 30 to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array 31 of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed. <IMAGE>

Title: Method for forming contacts in a semiconductor device
Inventor: RYOU EUI KYU
IPC: H01L21/60
Filed: 1995-10-25
Abstract: In a method for forming contacts in a semiconductor device, for example, in the form of a transistor (14, 16) on a semiconductor substrate (11), a pad conductive layer (18) is formed on an insulating film (17) provided over the resulting structure. The conductive layer is planarised by an insulating film (19). A photoresist film pattern formed on the planarised structure by use of a contact mask is used as a mask during etching of the insulating film (19) partially to expose the pad conductive layer (18). The exposed portions of the pad conductive layer are selectively over grown to form a second conductive layer (21) which will provide contacts for the device. The insulating film (19) is then etched using the pad conductive layer (18) as a mask to form an insulating film pattern (19'). Both the over grown second conductive layer (21) and the pad conductive layer (18) are fully etched to a desired depth, and the etched portions of the conductive layers are filled with another insulating film (22) to planarise the structure. A bit line (23) is formed on the planarised structure such that the bit line is in contact with the semiconductor substrate by way of the contacts formed by the conductive layer (21). The method enables the formation of micro contacts, improves the reliability of the semiconductor device and achieves high integration. <IMAGE>
