Abstract: A raster scanned video display for high resolution graphics on to which a graphical cursor can be superimposed. Cursor data corresponding to the next raster line of the image is read out of a data store (l0) during the line blanking interval and stored in a fast memory (30). During scanning of that next raster line the cursor data is combined with the image data. By combining the cursor data with the image data in this way, on a line-by-line basis, storage space requirements in the fast memory (30) are greatly reduced.

Abstract: Sand from a hopper (12) is fed onto a conveyor belt (22) in a layer 15 of uniform thickness. The temperature of the sand is measured by a plurality of thermocouples (42) spaced across the width of the layer. The resistivity is measured by measuring the resistance between two parallel conductive plates (40) transversely spaced across the layer. A sensor (44,46) measures the speed of the conveyor and a process controller (300) responds to the measured values and a manually entered desired moisture content signal to control a valve (46) regulating the flow of water into a water mixing device (16), where water is mixed into the sand coming off the conveyor.

Abstract: A reconfigurable beam-forming network for use with a transmitter has a waveguide R-switch that is interconnected with a Magic T. The R-switch contains phasing elements and is connected to a dual-mode power-­dividing network, which in turn is connected to first, second and third region power-dividing networks, each having their own feed horn array. The R-switch can be moved to three different positions so that in a first position power is divided between two input ports of the dual-mode network on substantially a fifty-fifty basis with the power on the two input ports being out of phase on a positive basis. In a second position of the R-switch, power is also divided on substantially a fifty-fifty basis between the two input ports but the power is out of phase between the two ports on a negative basis. In a third position of the R-switch, substantially all of the power entering the R-switch is passed into the first input port of the dual-mode network. The power being fed to the feed horns of any one of the regions has the same phase. In a variation of the invention, the R-switch and Magic T are replaced by a variable phase shifter and Magic T.

Abstract: A VTR is responsive to designation of an index scan mode for detecting an index signal recorded on a control track of a tape with the tape being traveled at high speed. During high-speed traveling, a video signal received by a contained tuner is outputted and applied to a monitor receiver. Every time the index signal is detected, the starting portion of each recorded program is reproduced in a normal reproducing mode during a short time period and time-base compressed, to be combined with the above described received video signal. The combined video signal for picture-in-picture display is applied to the monitor receiver externally provided, so that a received video signal is displayed on a main screen while a reproduced video signal is displayed on a subscreen. When a short time period elapsed, PIP control is cancelled, so that a high-speed traveling mode is established until the next index signal is detected. When a user turns an operation mode setting switch on, the contents recorded on the tape can be monitored in various desired modes so long as the operation mode setting switch is turned on, irrespective of the mode.

Abstract: A tape-loading mechanism for a compatible recording/-reproducing apparatus for selective use with a relatively large-size tape cassette (2) and a relatively small-size tape cassette (3), wherein the apparatus comprises a main chassis (4) on which the large-size tape cassette is to be positioned, a floating chassis (61) on which the small-size tape cassette is to be positioned and which is mounted to the main chassis for displacement in a direction normal to the principal plane of the main chassis, a pair of tape loader assemblies (10, 11) movably on the main chassis for taking out a tape from the large-size tape cassette positioned on the main chassis, or from the small-size tape cassette positioned on the floating chassis, and for loading the tape against a rotary head assembly (6), and a floating-chassis drive linkage (83) connecting a drive cam (44) to the floating chassis for moving the latter between a working position and a retracted position.

IPC: C08J5/14

Abstract: This invention relates to abrasive products having a resinous binder which holds and supports abrasive grains on a backing sheet or in a fibrous sheet. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g., heat resistance. In order to obtain the proper coating viscosities, solvent is commonly added to these binders. When polyester backings are used, curing temperature is limited to about 130°C, resulting in long cure times. The long cure time along with solvent removal necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include the formation of defects at the suspension rods, inconsistent cure due to temperature variations in the ovens, sagging of the binder, wrinkling of flexible webs, and shifting of abrasive grains. Although radiation curable resins solve the problems associated with thermally curable resins, with respect to festoon ovens, radiation curable resins are generally more expensive than thermally curable resins. 
     This invention provides an abrasive product comprising abrasive grains bonded together or bonded to at least one major surface of a backing sheet, by a binder formed from a precursor comprising an aminoplast resin having on average at least 1.1 pendant α,β-unsaturated carbonyl groups per molecule. The binder is formed by curing the precursor at the α,β-unsaturated site of the carbonyl group, by radiation energy or by heat, in the presence of an appropriate initiator system. The aminoplast resin can also contain pendant amino or hydroxy functional groups, which allow polymerization with condensation curable resins, such as phenolic, melamine, urea, urethane, and furfural resins. Polymerization at the unsaturated site of α,β-unsaturated carbonyl group can be effected either by radiation energy or by heat, and curing at the sites of the amino or hydroxy functional group can be subsequently effected by heat.

Abstract: An advanced MESFET switching structure includes an interdigitated source region (48a, 48b) and an interdigitated drain region (46a, 46b, 46c), and a gate electrode region disposed between adjacent portions of the interdigitated source and drain regions having a series gate electrode (47a-47d) in Schottky barrier contact therewith. The use of the series connect gate electrode (47a-47d) rather than conventional parallel coupled gate fingers eliminates the need for airbridge overlays to interconnect the source regions as in a conventional MESFET transducer. Moreover, the topography permits smaller MESFET structures and thus higher integration of circuits employing the advanced MESFET switch structure. The smaller transistors have lower parasitic reactances. All interconnections (46, 47e, 47f, 47h, 47i, 48) for drain, gate, and source electrodes are disposed on the active layer portion (44a) of the transistor providing an even smaller transistor structure.

Abstract: A technique for position-finding on a manufactured device such as an integrated circuit ("IC") or a printed circuit board ("PCB"), relating the observed image to a description such as the CAD database that was used to create the devices. The technique contemplates providing an optical image of the surface of the device, obtained  with an imaging device such as a video camera and a microscope, generating a synthetic CAD image from the CAD database, subjecting both images to a filtering operation (Laplacian of Gaussian convolution), binarizing (taking the sign of) the results, and correlating the two filtered  and binarized images (referred to as "processed" images) to determine relative alignment. One application of the invention is to allow precision  positioning of a positioning head relative to a workpiece such as placing an IC device (12) on a PCB (15). A positioning head (17) to which a camera (22) is mounted  is driven to the approximate location of the IC site by a positioning mechanism. The positioning mechannism need not be accurate for large increments of travel, but must be capable of providing small relative displacements with high precision. The camera image of the area near the IC site on the PCB is filtered and binarized, and correlated with a processed CAD image of the region surrounding the IC site. This establishes the actual position of the camera (and therefore the positioning head). The positioning head is then moved by the indicated amount.
