Abstract: A process is disclosed for forming a patterned silicide layer overlying a processed semiconductor substrate (10), the substrate having insulator regions (40, 50) and insulator-free regions (20, 30, 70) on an exposed surface thereof. The process comprises the following steps: co-depositing silicon and a refractory metal such as titanium, Zirconium, tungsten, molybdenum, cobalt, vanadium, or nickel,on the exposed surface of the substrate to form a metal rich silicide (80) thereon; annealing the metal rich silicide such that it reacts with the underlying insulator-free regions to form a reacted silicide (90, 100, 110) without reacting with the underlying insulator regions; and exposing the substrate to a wet etchant which removes the unreacted portions of the metal rich silicide without removing the reacted silicide. Depending on the refractory metal used, the etchant is either a concentrated basic peroxide etchant comprising ammonium hydroxide, or a concentrated acid peroxide etchant comprising hydrochloric acid or sulfuric acid.

Abstract: A method for computer image generation simulated visual scenes for applications such as flight training. The processing to generate the image takes place in three sequential stages: Controller, Geometry Processor, and Display Processor. At any point in time, the stages are processing data forthree consecutive scenes. Each scene is comprised of a plurality of faces. Processing prior to the Display Processor accomplishes clipping and perspective transformation of faces. The Display Processor then generates the scene with pipeline processing accomplishing four major tasks: span detection or windowing, span sequencing, mask processing, and color processing. The improved realism of the computer generated image includes application of area-times-color smoothing, using fractional face areas to improve scene quality and reduce quantizing artifacts.

Abstract: An injection mould (1) has a mould cavity (2) divided into a product forming part (4) and a shrinkage compensating part (5) which communicates with the part (4) through an opening (6). The volume of the part (5) can be reduced by moving a plunger (8) upwards. In use, plastics material is injected into the two cavity parts (4 and 5) through a gate (3) and as the material cools and shrinks, the plunger (8) is moved upwards until it is flush with the bottom surface of the part (4). The volume of the part (5) relative to the part (4) necessary to compensate for shrinkage and avoid distortion of the product as it cools will depend upon the nature of the material and other factors. Generally, however, satisfactory results are obtained with the part (5) having a maximum volume of from 4 to 6% of the volume of the part (4).

Abstract: An analogue-to-digital converter comprises a feed-­forward arrangement in which, in a first stage, the analogue input signal is applied via a filter 34 to a subtractor 26 along a first path and is applied via a second path to an analogue-to-digital converter 23 followed by a filter 24 and then converted back into analogue form to be applied via a filter 33 to the subtractor 26. The output of the subtractor 26 is therefore an error signal representative of the difference between the analogue input signal and the predicted signal in analogue form. The error signal is applied to an analogue-to-digital converter 30 and is combined at 31 with the predicted signal in digital form taken from the output of filter 24 via filter 32 to produce the digital output signal. Control means 14 are provided to provide phase and gain matching between different parts of the circuit and the filter 24 is such that its output noise spectrum is arranged to be shaped so as to include a null around the quarter sampling frequency, enabling a low resolution D-A converter 25 to be used.
