    Abstract: 2-dimensional nanostructured tungsten carbide which is obtained by control of the alignment of nanostructure during growth of tungsten carbide through control of the degree of supersaturation and a method for fabricating same are disclosed. The method for fabricating 2-dimensional nanostructured tungsten carbide employs a chemical vapor deposition process wherein a hydrogen plasma is applied to prepare 2-dimensional nanostructured tungsten carbide vertically aligned on a nanocrystalline diamond film. The chemical vapor deposition process wherein the hydrogen plasma is applied includes: disposing a substrate with the nanocrystalline diamond film formed thereon on an anode in a chamber, disposing a surface-carburized tungsten cathode above and at a distance from the substrate, and applying the hydrogen plasma into the chamber.

  • Patent number: 6422824
    Abstract: A getter assembly for use in a vacuum display panel is described. The novel getter assembly can be provided including both a non-evaporative getter and an evaporative getter which are uniquely positioned juxtaposed to each other such that ions emitted by the evaporative getter upon activation substantially shield the non-evaporative getter so that gases emitted by the non-evaporative getter when activated does not affect the state of vacuum in the vacuum display panel. A preferred embodiment of the present invention novel getter assembly is shown for vacuum display panels that have sufficient thickness in the cavity so that the getter assembly can be installed inside the cavity.

  • Patent number: 6407500
    Abstract: A flat vacuum envelope is provided where an anode electrode is conductively connected to the contact portion of a high-voltage supplying lead with high reliability so that the connection electrode plate is not stripped from the anode electrode (a). A field emission region (1a), which is formed of a gate layer and emitters, is laminated on a first glass electrode (1). An anode electrode (2a), which is formed of a fluorescent display substance and a transparent electrode, is laminated on a second glass substrate (2). An exhaust tube (4) is formed to the first glass substrate (1) to evacuate the inside of the vacuum envelope. The lead (5) is connected to the anode electrode (2a) via the connection anode plate (6). The connection anode plate (6) is joined to the anode electrode (2a) by the resilient member (20) so that the conductivity thereof is not impaired while the exhaust tube (4) is being sealed.

  • Patent number: 6369508
    Abstract: The invention proposes arranging a getter (7) made from niobium on the electrode rod (4) of a mercury short-arc lamp, the two following conditions being fulfilled: D>1.8·d and &agr;≧20°. In this case, D and d denote a diameter of the relevant electrode head (2) or the associated electrode rod (4), and &agr; denotes an angle which is defined by the longitudinal axis of the electrode and an imaginary connecting line between the end of the getter (7) averted from the electrode head, and a point on the perpendicular, running through the end of the electrode rod on the electrode head side, to the electrode longitudinal axis. The point mentioned corresponds to the projection of the maximum radius of the lateral surface of the electrode head onto this perpendicular. An improved maintenance of the lamp is thereby achieved.

  • Patent number: 6356015
    Abstract: The invention is directed to an improved hollow cathode lamp (15). In the preferred embodiment, the lamp is comprised of a stem (23), a cathode lead (18) which passes through the stem, and a getter (26). The improvement includes a flash shield (28) positioned between the getter and the stem, whereby the flash shield will limit the deposit of getter metal on the stem when the getter flashes. The flash shield may be a circular disk and composed of nickel. The flash shield may include an evacuation passage (46). The flash shield may also be capable of being heated to about 1000° C. during flashing, whereby the flash shield may be heated so as to convectionally repel the getter metal when the getter flashes.
