    摘要: A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

    摘要: Significantly improving in the contrast ratio of a visual image display using a liquid crystal layer and a fiber optic faceplate with tilted fibers. One preferred embodiment of the visual image display includes a liquid crystal layer, a first polarizer and an optical fiber faceplate with many substantially parallel fibers. Each fiber has an axis which forms an oblique angle with the normal to the front surface of the liquid crystal layer. All the oblique angles are substantially equal to a typical oblique angle. The typical oblique angle is selected along the direction that substantially maximizes the contrast ratio of the display.

    摘要: An apparatus and method for directly overwriting data on a magnetooptic data storage medium. The apparatus includes a magnet (16) disposed adjacent to a recording medium (14) which provides a static magnetic field which interacts with the medium (14). The interaction is broadbased, having an area including multiple tracks (17) of the medium that encompass up to an entire data band. A first laser focuses a continuous laser beam (22) onto a track (17) of the recording medium within the location of the reversed magnetic field (18). This first laser beam (22) provides for erasure of the medium. A second laser focuses a pulsed laser beam (26) onto the erased track (17) within the location of the nonreversed magnetic field (20). This pulsed laser beam (26) provides for writing to the medium. Typically, the magnetic field provided by the magnet (16) is static, but its orientation changes with the distance along the data tracks (17) in that its component perpendicular to the medium (14) switches direction within the field of view of an optical system employed to focus the laser beams (22,26). The magnet (16) may be stationary, or movable such that it is positionally synchronized with the laser writing operations. The magnetic field may also be offset or contoured to compensate for motion of the medium during cool down subsequent to a writing operation. The method in accordance with the present invention includes the steps of applying a static magnetic field to a magnetooptic recording medium (14) whose magnetic field encompasses up to a full data band; focussing a first laser beam (22) onto a track (17) of the recording medium at the location of the reversed magnetic field (18) to erase the medium; and focussing a second laser beam (26) onto the erased track (17) of the recording medium at the location of the nonreversed magnetic field (20) to write to the medium.

    摘要: A printing system (30, 40, 40′, 50, 50′) includes at least one ejector coupled to a reservoir (38) that is configured to contain a printing composition including a hydrocarbon having at least one unsaturated bond. The hydrocarbon is configured to at least one of polymerize or crosslink in the presence of a reactive species. The at least one ejector is configured to eject the printing composition onto a surface (34, 36, 10). The system (30, 40, 40′, 50, 50′) further includes a corona generator (32, 32′, 32″, 32′) configured to generate the reactive species in situ. The corona generator (32, 32′, 32″, 32′) is positioned with respect to the reservoir (38) such that the reactive species is exposed to the printing composition after the printing composition has been ejected onto the surface (34, 36, 10). The polymerizing and/or the cross-linking of the hydrocarbon is configured to form a polymer matrix (12) from the ejected printing composition.
