Abstract: A raster-scanned video display apparatus includes a double image frame buffer to store individual pixel display data. and a valid count buffer to hold a count for each pixel. Current valid counts are stored at times of image buffer updating, which updating includes storing display data changes and a fraction of the total display (background). At times of display, current counts from the count buffer are tested against valid counts as stored for each pixel in the valid count buffer to determine the selection of display data from the image frame buffer or alternatively background data. A window frame buffer resolves the display into windows that are accommodated by the system with valid counts for each window.

Abstract: A transfer apparatus (10C) is disclosed for trans­ferring a tail (TC) of a web (WC) from a press roll(12C) to a dryer (14C) of a dryer section (16C). The apparatus includes a lead-in roll (22C) which is disposed adjacent to and spaced relative to the press roll for leading the tail of the web from the press roll towards the dryer. A dryer felt (20C) extends around the lead-in roll and from the lead-in roll to the dryer such that the tail is supported by the felt from the lead-in roll to the dryer. The felt and the dryer define therebetween a positive air pressure in-going nip. A rotatable suction roll (30) is disposed adjacent to and on the opposite side of the felt relative to the in-going nip such that in use of the apparatus, the suction roll generates a flow of air from the positive air pressure in-going nip through the felt such that when the tail of the web is being transferred from the press roll towards the dryer, the tendency for the positive air pressure in the vicinity of the in-­going nip to prevent threading of the tail between the felt and the dryer is inhibited.

Abstract: A character recognition system and method is disclosed which uses the generalized Hough transform. A template table which stores edge point parameters to be used for the generalized Hough transform is compressed so as to include only predetermined parameters, and is then divided into a plurality of template tables which are respectively loaded in the memories of a plurality of subprocessors operating in parallel under the control of a main processor. In performing recognition processing, these subprocessors operate in parallel according to their related partial template tables.

The grinding wheel is formed with first and second grinding surfaces usable for grinding a cylindrical surface and shoulder end surface of a workpiece, respectively, and first and second reference surfaces parallel to the first and second grinding surfaces, respectively. The positions of the first and second reference surfaces and the first and second grinding surfaces are detected with touch bars before each dressing operation so as to obtain a first distance between the first grinding surface and first reference surface, and a second distance between the second grinding surface and second reference surface. After that, a first dressing amount for dressing the first grinding surface and a second dressing amount for dressing the second grinding surface are so determined that the fist distance and the second distance would have a predetermined constant relationship after dressing operation. The first grinding surface is then dressed by the first dressing amount, while the second grinding surface is dressed by the second dressing amount.

Abstract: A method of using a technique of fuzzy inference for partioning a particle size distribution diagram indicative of a relationship between particle size and its frequency of a mixture of several kinds of granular substances, such as white blood corpuscles including lymph corpuscles, monocytes and granulocytes, to define particle size regions for the respective substances. More particularly, some estimation points are selected on the abscissa of the particle size distribution diagram and some characteristic parameters are calculated at each estimation point with the corresponding frequency. A fuzzy production rule for each characteristic parameter is applied to seek an estimated value of the estimation point and the estimated values for all characteristic parameters at each estimation point are combined to obtain a composite estimated value. The estimation point corresponding to the greatest one of all resultant composite estimated values is appointed to an objective partition point.
