  • Patent number: 6670949
    Abstract: An apparatus for locating a point physically touched and producing an electrical signal corresponding to the location includes an insulating substrate; a resistor touch pattern supported on the insulating substrate; and a protective insulating plate arranged over the resistive touch pattern. The resistive touch pattern has a plurality of strip resistors parallel to a center line; a plurality of linear resistors connected to the strip resistors, the resistance of the linear resistors decreasing with distance from the center line; first and third terminals positioned on an intermediate point of alternate edges of the touch pattern; and second and fourth terminals, positioned on an intermediate point of other alternate edges of the touch pattern. The resistive value of the linear resistors selected for a corresponding strip resistor so as to produce equal potential at a corresponding selected point on all said strip resistors.

  • Patent number: 6661399
    Abstract: A liquid crystal display (LCD) device having a digitizer. A liquid crystal panel is supported by a lower frame having a side wall portion. A digitizer is located on the liquid crystal panel. An upper frame having a front surface with an opening region and a side wall portion is located over the digitizer such that the tipper frame pressurizes a peripheral portion of the digitizer. The opening region is formed at a location corresponding to the display region of the liquid crystal panel. The upper and lower frames mate to hold the liquid crystal panel and the digitizer in place. The upper frame is beneficially metallic to provide electrical shielding of conductors on the digitizer. Common electrical circuits are shared by the digitizer and the liquid crystal panel.

  • Patent number: 6645399
    Abstract: Compositions and methods have been discovered for inhibiting corrosion of metals, particularly iron alloys, in contact with fluids, either hydrocarbons, alcohols, or aqueous fluids, employing mercaptoalcohols. The mercaptoalcohols should have at least one water solubilizing hydroxyl group. In particular, suitable mercaptoalcohols have the formula: (HS)n—R—)(OH)m where R is a straight, branched, cyclic or heterocyclic alkylene, arylene, alkylarylene, arylalkylene, or hydrocarbon moiety having from 1 to 30 carbon atoms; n and m each independently averages from 1 to 3; and the heteroatom in the heterocyclic moiety substituent, if present, may be N, O, S and/or P. Preferred mercaptoalcohols include 2-mercaptoethanol, 2-mercaptopropanol, 1-mercapto-2-propanol, and 2-mercaptobutanol, in part because they are soluble in many fluids. These corrosion inhibitors show improved inhibition of both generalized and localized corrosion, specifically in high shear and high flow environments.

  • Patent number: 6573155
    Abstract: Process steps for bonding substrates of a touch panel. Steps include forming an insulator layer around a flexible printed cable (FPC) contact formed on electrodes, forming a low resistive metal layer, to which the FPC is attached, on the insulator layer, forming dot spacers out of insulating material within the active area. Next, connecting the FPC with a band region formed by the insulator layer and the low resistive metal layer after the insulator layer, the low resistive metal layer and the dot spacers have been formed. Finally, bonding the substrates for reading an X coordinate and for reading a Y coordinate after connection between the insulator layer, the low resistive metal layer, the dot spacers and the FPC.

  • Publication number: 20030060373
    Abstract: Non-polymeric drag reducing agents in the form of maleated fatty acids and the esters thereof and the organic, inorganic or amine salts thereof are described herein. These additives are useful to reduce drag in hydrocarbon fluids and multi-phase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream, nor is grinding (cryogenic or otherwise) of the additive necessary to form a suitable drag reducing agent. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming.

  • Publication number: 20020089492
    Abstract: A flat panel display with input device having enhanced assemblability and lowered failure rate is achieved by connecting a touch screen driver with a display driver. Signal distortion is reduced by simplifying wiring. Reduction of signal distortion in an input device or a flat panel display and economic benefit in its manufacture occurs by constructing a display driver and a touch screen driver on the identical printed circuit board (PCB).
