Patent CA-2059033-C (CA)
Inventor: UMEKI TSUNENORI
IPC: G06F9/38
Filed: 1992-01-08
Granted: 1996-03-05
Abstract: The following measures are taken to obtain a microcomputer which securely fetches an instruction code from a low-speed memory to improve the reliability when the instruction code is not present in an instruction queue buffer. When the requested instruction code is not present in the instruction queue buffer, a CPU judges whether the memory to be accessed is a high-speed memory or low-speed memory. When the memory to be accessed is a high-speed memory, the CPU fetches the instruction code directly from the memory by skipping the instruction queue buffer. Meanwhile, when the memory to be accessed is a low-speed memory, the CPU does not skip the instruction queue buffer but it waits for the instruction code to be fetched to the instruction queue buffer. Thus, the instruction code is securely fetched, the reliability is improved, and the timing is easily set for design.

Title: Method and system for compressing data in a multi-channel image processing system
Inventor: VIETH JOHN O G
IPC: H04N1/417
Filed: 1992-03-19
Granted: 1999-03-30
Abstract: A system and method for processing image data from a document and for producing a compressed binarized version of the image data for transmission to or use by subsequent users.  Processing of the image data is done in parallel after the scanning of the document is started but before the entire document is scanned.  A splitter is used to divide a scan line of image data produced by an imager at the scan line into a plurality of channels, with each channel having at least one overlap area of pixels and with the overlap areas of pixels being used to avoid errors between channels.  Thresholding and compression are performed by each one of the channels in parallel. The compression is performed in a direction which is perpendicular to the direction of scanning and conforms to a standard compression algorithm like CCITT Group 4.

Title: Increased pile density composite elastic material
Inventor: COHEN BERNARD
IPC: B32B27/12
Filed: 1992-08-31
Granted: 2002-10-08
Abstract: Disclosed is a method of making a lanate composite elastic material including the steps of applying a tensioning force to elongate at least one elastic sheet; inserting substantially individualized fibrous materials into the elastic sheet by mechanical needling the elastic sheet while it is maintained in an elongated condition; and releasing the tensioning force so the attached fibrous materials are positioned closer together by the recovery of the elastic sheet. The resulting lanate composite elastic material has stretch and recovery properties, bulk, and desirable insulation properties. One or more layers of the lanate composite material may be combined with other layers of material to create a multi-layer structure. Also disclosed is a method of making in increased pile density composite elastic material including the step inserting substantially individualized fibrous materials into an elongated elastic sheet by stitchbonding, malipole stitchbonding, or tufting or adhering substantially individualized fibrous materials to an elongated elastic sheet by flocking techniques. The density of attached fibrous materials in the resulting increased pile density composite elastic material is greater than could be achieved by conventional fiber insertion or adherence techniques while still maintaining desirable elastic properties and bulk.

Abstract: Apparatus and a method is disclosed for processing wheat to produce white flour by substantially removing the bran layer from the endo-sperm and germ portions of the wheat grain and grinding the resulting wheat product to a relatively fine state in a roll and classification train that is much simpler than prior milling equipment. Thirteen grinds with intermediate sifting are replaced with one flattening and four grinding stations and three sifts. The initially tempered wheat is passed between spaced, smooth surfaced compression rolls (R1) which flatten the wheat grains and then directed between corrugated spiral breaking rolls (R2) rotated at different rotational rates with each roll having at least twenty surface corrugations per circumferential inch. The comminuted product is then directed between corrugated spiral, grinding rolls (R3) rotated at different rotational rates and each having at least twenty six corrugations per circumferential inch, After selective classification through mesh sieves (51, 52, 53) the comminuted wheat is further reduced in size by passage between corrugated spiral reduction rolls having at least about thirty-six corrugation per circumferential inch which are also rotated at differential rotational rates. The final flour is produced by di recting the comminuted product between smooth surfaced finishing rolls rotated at different rates of rotation.

Abstract: A technique for generating gated clock signals for use in enabling various operating gating units in a data processing system in which an internal reference clock signal is used to generate both processor clock signals and the gated clock signals such that the latter signals are substantially synchronous with the processor clock signals.  D-flip-flop circuitry together with a delay unit having an adjustable time delay are used to generate a gated clock signal.  The overall time delay, from the time of which the circuitry is enabled until the gated clock signal is produced, is appropriately set by selecting the required time delay so that the overall time delay is essentially the same as the time delay required to generate the processor clock signals.          Accordingly, the edges of the gated clock signals can be made to coincide with the edges of the processor clock signals.  The use of such gated clock signal generation circuitry can reduce the time needed to generate the gated clock signals from that required by previously used register PAL circuitry to improve performance of the processing system.
