  • Patent number: 6012805
    Abstract: Apparatus is disclosed for controlling ink in a continuous ink jet printer in which a continuous stream of ink is emitted from a nozzle, wherein an ink stream generator establishes a continuous flow of ink in a stream such that the stream breaks up into a plurality of droplets at a position spaced from the ink stream generator. A stream deflector includes a body having a surface positioned adjacent to the stream between the ink stream generator and the position whereat the stream breaks up into droplets such that the stream contacts the surface and is deflected at least in part due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy.

  • Patent number: 5963235
    Abstract: A continuous ink jet printer emits a continuous stream of ink from an ink stream generator. The stream breaks up into a plurality of droplets at a position spaced from the ink stream generator. A stream deflector includs a control surface positioned adjacent to the stream between the ink stream generator and the position whereat the stream breaks up into droplets such that the stream contacts the control surface and is thereby deflected due to a gain in free energy caused by physical contact between the ink in the stream and the control surface. Apparatus may be provided to modulate the position of the control surface to change the direction of the stream between a print direction and a non-print direction.

  • Patent number: 5726080
    Abstract: A methodology for producing an edge aligned implant beneath an electrode with reduced lateral spread, comprising the steps of: providing a dielectric layer on a substrate; forming an etch-stop layer on the dielectric layer; forming a sacrificial material layer on the etch-stop layer; patterning the sacrificial layer with openings to expose the etch-stop layer and which openings corresponding to gate electrode positions; implanting dopant atoms through the opening into the substrate in regions adjacent to at least one edge of the opening in the sacrificial layer; depositing electrode material into the openings and onto the sacrificial layer; forming an electrode layer, either by itself of with another layer deposited or grown over it to allow alteration to provide an etch rate differential. The material that etches relatively slowly becomes or protects the gate electrode region. The alteration is done by a process such as diffusion or irradiation.

  • Patent number: 5241199
    Abstract: A charge coupled device having a layer of a semiconductor material on a surface of a substrate body of a semiconductor material. The layer is of a material which can be epitaxially deposited on the body with good crystalline quality. The material of the layer has a conduction band and/or valence band which is different from that of the body so as to provide a discontinuity in the energy level of the conduction band and/or valence band at the junction of the layer and the body during the operation of the charge coupled device. At least one electrode is over and insulated from the layer. The discontinuity in the conduction band and/or valence band creates a well in which photogenerated charge is collected.

  • Patent number: 5093874
    Abstract: A fully integrated electro-optic page-scanner comprises an optically transparent waveguide made from an electro-optic polymer, and an electrode structure including a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. According to the invention, the addressable electrodes are disposed on a photoconductive substrate which facilitates poling of the polymer waveguide to rander it electro-optic in nature. During the poling process, the photoconductive substrate is made electrically conductive by flood illumination, while a uniform electric field is established between the substrate and a transparent electrode which overlies the waveguide layer, opposite the addressable electrodes. Preferably, the photoconductive substrate comprises undoped silicon which enables certain electrode-addressing circuitry to be integrated within the scanner structure.
