Abstract: A card transaction processing apparatus for executing transaction processing utilizing a card is connected to a registration processing unit which performs sales data registration processing. When sales data is transmitted from the registration processing unit, there is an input of data necessary for a card transaction. Card transaction processing is executed based on the sales data transmitted by the registration processing unit and the entered data necessary for the card transaction. Destinations to which the results of the card transaction processing are to be outputted are selected in dependence upon the contents of these results.

Abstract: The present invention provides methods and apparatus for rapid compression of images composed of pixels into high-resolution, compressed icon images, and for dynamic fault imaging of operating faults in integrated circuit devices employing such methods. Displaying a plurality of such icons juxtaposed on a screen permits ready tracing of a fault in an IC device under test, even by persons having little knowledge of the functionality of the devices. 
     In accordance with the invention, an image made up of  n x n  pixels may be compressed into an icon of  p x p  pixels, where  n = p · q  and  q  is an integer, by dividing the image into  p  tiles of  q x q  pixels, selecting  q  pixels from each tile, where each of said selected  q  pixels is representative of predetermined directional orientations within the tile, and calculating the mean value of the selected  q  pixels, to produce a single pixel representative of the tile. The pixels representative of said tiles thus form an icon of  p x p  pixels. Each of the selected  q  pixels is preferably uniquely representative of a horizontal row of  q  pixels, a vertical column of  q  pixels, and a pair of mutually-orthogonal diagonal lines of pixels of the tile. Edge enhancement may also be performed to sharpen the features of the resulting icon. 
     The invention further includes a method of dynamic imaging of operating faults in integrated circuit devices. The methods are preferably carried out in the general purpose processor of an engineering workstation, which may be associated with an electron beam test probe for acquisition of the images.

Abstract: A tyre construction comprises an outer annular casing 10 of resilient material having an outer circumferential tread portion 11 and two spaced side walls 12 extending inwardly from the tread portion and terminating in respective bead portions 13 which are arranged to engage the rim of a wheel hub. An annular base member 15 of resilient material extends between, and is bonded to, the side walls in the vicinity of the bead portions so as to define a closed annular space between the outer casing and the base member. An inner core 22 of softer resilient material fills the annular space. The annular base member 15 is formed at opposite outer edges thereof with peripheral flange portions 18 which overlie and are bonded to the respective side walls of the outer casing. The pressure exerted on the flange portions by the solid inner core serves to press the flange portions against the side walls of the outer casing.

Abstract: An anti-weaving conveyor belt comprising a belt body 1 which comprises a heat-resistant, fluoroplastic-impregnated sheet 2 and at least one elongate guide member 4 fixed to the back of the belt body longitudinally thereof, said guide member comprising a number of cords 5a, 5b, 5c.... twisted together to form a preferably round or square profile, each cord comprising a number of heat-resistant, fluoroplastic-impregnated fibers twisted together. The guide member is joined to the back of the belt body by stitches of heat-resistant, fluoroplastic-impregnated strands 10. Thanks to the sewing of the guide member to the belt body, the conveyor belt can be made of a material of good releasability even if the material has no good bonding properties which would otherwise permit the guide member to be fixed to the belt body by an adhesive. Such a belt conveyor can be used in a high temperature environment.

Abstract: A spark timing control for an electronic internal combustion engine ignition apparatus that provides a constant spark advance regardless of engine speed. A series of crankshaft pulses (20A,20B) are developed which occur at each 60 degrees of rotation of the crankshaft. The control has a source (30) of constant frequency clock pulses which are counted up by an up-counter (28) during 60 degree periods. The count attained by the up-counter during a 60 degree period is loaded into a down-counter (38). The up-counter is now counted up at a constant rate from zero and the down-counter is counted down at a constant rate from the count magnitude that was loaded into the down-counter. When the count magnitudes of the two counters are equal, a digital comparator (50) that is connected to the counters develops an output signal (56) that can be used to cause the firing of a spark plug.

Abstract: An apparatus (10) for producing high intensity radiation has electrodes (15,17) positioned within an elongated cylindrical arc chamber (12) across which an arc discharge can be established. Liquid is injected into the arc chamber to produce a vortex motion therein to form a cylindrical liquid wall adjacent to the chamber, which constricts the arc by cooling an outer periphery thereof. Gas is injected into the arc chamber to produce a vortex motion adjacent the cylindrical liquid wall. An exhaust structure actively exhausts the liquid and gas from the arc chamber to reduce turbulence and restriction of fluid. This permits attainment of higher flux densities in the arc, and/or extension of electrode life. Preferably, the liquid and gas are exhausted actively by means of an ejector pump which ejects pressurized liquid into the gas and liquid leaving the arc chamber. The ejector pump pressurizes the exhausted gas and liquid sufficiently to permit the gas to be separated and recycled back to the arc chamber, without requiring an additional compressor to increase gas pressure.

Abstract: An electrically-erasable, electrically-programmable ROM or an EEPROM is constructed using a floating-gate transistor (10) with or without a split gate. The floating-gate transistor (10) may have a self-aligned tunnel window (26) or sublithographic dimension positioned on the opposite side of the source (11) from the channel and drain (12), in a contact-free cell layout, enhancing the ease of manufacture and reducing cell size. In this cell, the bitlines (17, 19) and source/drain regions (11,12) are buried beneath relatively thick silicon oxide (24a, 24b, 24c) and the floating gate (13) extends over the thick silicon oxide. Programming and erasing are accomplished by causing electrons to tunnel through the oxide in the tunnel window. The tunnel window has a thinner dielectric than the remainder of the oxides under the floating gate to allow Fowler-Nordheim tunneling. Trenches and ditches (27, 28) are used for electrical isolation between individual memory cells, allowing an increase in cell density.
