IPC: H01L29/812
Filed: 1988-01-05
Abstract: A method of providing a self-aligned gate (SAG) transistor or FET is disclosed. The method maintains the large alignment tolerances inherent in the SAG FET. A reduction in gate resistance is accomplished by including a second gate metallization, which is highly conductive, after the n+ implant and activation anneal. This precludes unavoidable degradation of the conductivity of the second gate metal by interdiffusion with the first (refractory) gate metal. The large tolerance for misalignment of the gate mask level is maintained by a planarization of the anneal cap, into which windows are etched to the first gate metallization. The remaining adjacent encapsulant then acts as an insulator over the FET channel region and allows for gross misalignment of the second gate metallization without FET performance degradation. Using this technique, substantially increased performance can be obtained from a self-aligned FET while maintaining the basic simplicity of the RG process.

Abstract: A system extracts a set of size invariant, rotation invariant features from pixel data of a character and sends the set of features to a statistical decision tree to effectuate automatic recognition of a character. The set of extracted features includes a first group obtained by generating arrays representable as dimensions and other geometric qualities of six minimum bounding rectangles rotated about the character, including the distances between the center points of the rotated bounding rectangles. A second group of features is extracted by generating a group of arrays representing the perimeter pixel locations, radii lengths, and direction codes. The arrays of that group are "resampled" to generate corresponding 64 point arrays. The resampled arrays of direction codes is smoothed and incremental direction codes are computed and compared to preselected thresholds to obtain features that indicate prominent convex and concave portions of the character. A third group of features is extracted by dividing a circle bounding the character into eight rings and 24 slices and counting the number of character pixels contained in each ring and in each slice. Various Fourier transforms, autocorrelations, moment calculations, and sorting operations are performed on many of the aforementioned arrays to yield further size and orientation invariant features. The distance between the centroid of the   largest hole of the character and the center of the character is computed. The ratios of the perimeters of first and second holes of the character to the outer perimeter are computed.

Abstract: For co-molding a plurality of articles from a plurality of polymeric materials, a preferred molding apparatus has a plurality of valve-controlled co-injection nozzles (296) and injection cavities (102). The polymeric materials (A to E) are melted and fed from their sources (202, 204, 206) by screw extruders (214, 216, 218) to a set of rams (232, 234, 252, 260, 262) which appropriately pressurize and move streams of the polymeric materials to feed blocks (296) each associated with or forming part of a respective nozzle (296) for injection into the related cavity (102). The streams leaving the rams (232, 234, 252, 260, 262) are conveyed along respective runner ducts (220, 222, 250, 257, 258) to a runner extension member (276) in a runner block (288), and in the runner extension each material sream is divided into a plurality of branch streams. Each branch stream is ducted to flow splitters in the runner block (288) for further division into plural feed streams equal in number to the number of nozzles (296), and the separate feed streams and then fed one to each nozzle (296). The apparatus is configured such that for each material, the plural feed streams reach their respective nozzles (296) after passage along ductings of the same length and geometry to ensure that the streams enter their nozzles as nearly as possible in the same condition, ready for injection. Each nozzle (296) receives the polymeric materials (A to E) as separate feed streams and combines them appropriately into a plural-layer, plural-material stream for injection. The nozzles all have pin and sleeve valves (800, 834) to control admission and flow of the different materials to their central channels (240) wherein the combined stream is formed. Valve operation is under microprocessor control (2040) and the valves - which are effectively substantially identical - are coupled to common valve actuating cams (850, 856) for operation in   unison, so that at any instant in the molding cycle the combined streams formed in the nozzles (296) for injection are as near as possible identical to one another. By appropriately controlling the pressures of the polymeric material streams and by appropriately controlling the timing of valve operating movements, precise control is obtainable whereby e.g. internal layers of the injected articles are positioned where best suited depending on the service required of the articles. 
     The method and apparatus are applicable to the production of injection or injection blow molded articles such as containers for commestibles and beverages.

Abstract: In a secure messaging system with several terminals 10, 10A, etc, 12 there are many system (control) messages, between the various terminals; these are liable to deliberate or accidental change of sequence, deletion, duplication, etc. To protect the system against this, an acknowledgement is sent for every message received (except a simple acknowledgement), and each station stores copies of the messages it has sent, deleting them only when acknowledged. When a new message is to be sent or a non-receipt of acknowledgement time-out occurs, a packet is sent with all previous messages in store prefixed to the new message, so the receiving station cannot act on the new message before receiving and acting on the previous messages. (There are known means for ignoring duplicated messages). Preferably there is chained serial authentication of the messages in the packet so that even if one is garbled, they can be acted on up to that point. For security and other reasons, user messages are in general not treated similarly but sent only once; with these, error control is a user responsibility.

Abstract: In a computer image generating system, the choice of a path for a vehicle model over a landscape is not restricted. Objects and features in an image to be displayed are defined by polygons. Plumb vectors, having a predetermined relationship with the vehicle model, are used to obtain samples of the terrain at the intersection between the vectors and polygons defining the group in the vicinity of the vehicle model. The vectors may sample in advance of the vehicle model in the direction of motion or under the vehicle model. The poly­gons may be encoded with characteristics of the terrain they define so that appropriate noise cues can be generated from information extracted at the intersection of the plumb vectors and polygons. Predetermined ones of the sample points are interpolated for inferring the contour and slope of the terrain before interaction between the vehicle model and interpolated terrain is determined. The display of an image is modified in response to the real-time interaction between the vehicle model and local topology to reflect such interaction at a predetermined viewpoint. An image generating system includes terrain sampling means, sampling processing means, display control means and audio generator means for presenting images with respect to a predetermined viewpoint wherein the images reflect real-time interaction between the vehicle model and the local topology of the image.
