  • Publication number: 20060044771
    Abstract: An electronic module includes a substrate, at least one surface mountable integrated circuit (IC) component and a conductive polymer. The substrate includes a plurality of electrically conductive traces formed on at least one surface of the substrate. The at least one surface mountable integrated circuit component includes a plurality of conductive pads formed on at least a first surface of the component and the conductive pads are electrically coupled to at least one of the conductive traces. The conductive polymer is in contact with at least a portion of a second surface, which is opposite the first surface, of the component and the substrate.

  • Patent number: 6480880
    Abstract: The claimed invention can be used to automatically determine what files are needed to optimally execute a computer program to a desired state. In one embodiment the invention automatically creates an optimized file containing the files that are necessary to reach the desired state of a computer program. One or more remainder files may also be created. A remainder file contains the files that may be used by the computer program after reaching the desired state of execution.

  • Patent number: 6051928
    Abstract: A plasma display panel includes front and rear substrates; anodes in a stripe pattern on a facing surface of the front substrate; a lower electrode coating the entire facing surface of the rear substrate; a dielectric layer coating the lower electrode; an upper electrode coating the dielectric layer in a pattern; and a lattice of partition walls between the upper electrode and the front substrate. The portions of the dielectric layer between the partition walls and not coated with the upper electrode form respective pixels. Sputtering is minimized and there is less damage to the electrodes by the gas, thus extending the length of use of the product. The ferroelectric material of the lower electrode has excellent resistance with respect to the discharge gas and the discharge can be initiated with a low initial discharge starting voltage since the ferroelectric cathode provides enough electrons for the discharge.

  • Patent number: 5982083
    Abstract: A cathode for an electron tube includes a layer of a electron emitting substance containing alkaline earth metal oxides containing 0.01--20.0 wt % of both a lanthanum compound and a magnesium compound or a lanthanum-magnesium compound disposed on a base metal including nickel as a major component and tungsten as a minor component. The tungsten prevents embrittlement and ensures a continuing supply of fill barium in the electron-emitting substance. The cathode enjoys full interchangeability with the conventional oxide cathode and a 15-30% longer life span.

  • Patent number: 5522109
    Abstract: A toothbrush comprises an elongate element with a brushhead on each end. The elongate element (10) is composed of a first curved portion (10a, 10b) on one end and a corresponding second curved portion (10b, 10a) on the other end. Each curved portion further comprises an outer section (14) and a holder section (12) integrally connected by a goose-neck shaped middle section (13), with the brushhead attached to the free end of the outer section such that the longitudinal axis of the brushhead (20, 30) is disposed at an angle to the longitudinal axis of the adjacent outer section (14) of the element (10). The toothbrush is pivotally fitted with a rotatable cover-cum-handle that allows either brushhead-carrying curved portion (10a, 10b) of the elongate element to be exposed and concealed in turn.
