  • Patent number: 8491966
    Abstract: Disclosed herein is a process for coating ceramic honeycomb bodies with a catalyst suspension comprising catalyst components as solids and/or in dissolved form in a carrier liquid. Parallel flow channels run through the honeycomb bodies. The walls of the flow channels have an open pore structure. To coat the channel walls and in particular also the interior surfaces of the pores with the catalyst suspension, the entry and exit end faces of the vertically aligned honeycomb bodies are each brought into contact with a perforated mask, with the perforated masks being arranged so that the open regions of the perforated mask on the one end face are opposite the closed regions of the perforated mask on the other end face and vice versa. The catalyst suspension is then pumped or sucked from below into the honeycomb bodies until it exits at the upper end face.

    Abstract: A coating fluid for forming a phosphor screen is coated on an inside surface of a glass panel having a wall portion provided with a wall portion edge at an outside surface of the glass panel. Then, the coating fluid on the inside surface of the glass panel is dried after facing the inside surface of the glass panel downward and placing the wall portion edge onto a panel support stand in a manner that the panel is supported on the support stand primarily by the wall portion edge. Since the glass panel is placed on the support stand in a manner that only the edge portion contacts the support stand, the scattering of coating fluid during this placement can be prevented. As a result, a uniform phosphor layer can be formed on the inside surface of the panel without decreasing the productivity for making such a glass panel on which a phosphor layer is formed.

  • Patent number: 5379507
    Abstract: A tank construction including an outer shell of steel material comprised of two half members welded together. The half members are formed by a deep drawing process. An inner shell of non-corrosive material is cast inside the outer shell by a rotational casting procedure with the external surface of the inner shell located adjacent the internal surface of the outer shell. The inner shell of non-corrosive material provides a substantially leak-fight liner for the outer shell to thus prevent contact between the contents of the tank and the outer shell. The rotational casting of the inner shell inside the outer shell is accomplished by charging the outer shell with a non-corrosive material and then subjecting the outer shell to a rotational casting movement while heat is applied to the outer shell. The outer shell serves as a mold for the inner shell wherein the mold (outer shell) becomes a permanent part of the completed tank.

Pressure from pump(76) is transmitted to the tank(10 by the liquid coating material and held for a prescribed time interval to prove tank integrity. The method avoids excessive shear, hence viscosity changes in thixotropic coating materials.

  • Patent number: 5290609
    Abstract: A dielectric film of a capacitor is formed using the plasma CVD apparatus. A thin Ta layer is deposited on a semiconductor wafer by using Ta(N(CH.sub.3).sub.2).sub.5 gas and H.sub.2 radicals. The thin Ta layer is then oxidized by O.sub.2 radicals to form a thin Ta.sub.2 O.sub.5 layer. An Si.sub.3 N.sub.4 layer is then formed on the Ta.sub.2 O.sub.5 layer by using SiH.sub.4 and NH.sub.3 gases. The Ta.sub.2 O.sub.5 layer and the Si.sub.3 N.sub.4 layer are alternately laminated one upon the other several times to form a dielectric film of laminated structure. The dielectric film can thus have a composition close to the stoichiometric composition and it can be made high in dielectric constant and excellent in withstand voltage.

  • Patent number: 5167983
    Abstract: A technique for fabricating a patterned conductor on the inner surface of a transparent tube comprises providing a source of conductive material inside a hollow tube and directing actinic radiation onto the tube wall where the deposition of a conductive pattern is desired to deposit conductive material thereon. That conductive deposit may be thickened by subsequent electroless or electroplating. The result is an improved magnetic resonance sensor comprising a hollow tube having "flat" conductor coils disposed on its interior surface.

  • Patent number: 5104686
    Abstract: Apparatus for applying a conductive coating of DAG material to the inner surface of a cathode ray tube (CRT) funnel includes a stationary DAG spray gun and a movable DAG rotating slinger. The CRT funnel is rotated to allow the stationary spray gun to deposit a first DAG coating on an intermediate flared portion of the inner surface of the funnel, including the location of its anode button. The DAG slinger, which includes a rotating disc for radially discharging the DAG, is then displaced through the neck portion of the CRT funnel toward the open, enlarged end of the funnel to deposit a second DAG coating which overlaps the first DAG coating. The apparatus includes a variable DAG flow control arrangement for depositing a DAG coating of uniform thickness over the inner surface of the CRT funnel, as well as a DAG cleaning and recovery arrangement for preventing DAG not deposited on the CRT funnel from escaping to the environment and for recovering this DAG for re-use.

  • Patent number: 4659445
    Abstract: In order to coat hollow bodies, which are open at one end, such as a metal can provided with a bottom, with a lacquer or the like, the hollow bodies are passed in a continuous operating cycle through en electrophoretic immersion bath in such a way, that they are rapidly and completely flooded with immersion bath liquid, so that they can be coated electrophoretically with a wet film in the immersion bath. After a sufficiently long coating time, the hollow bodies are lifted out of the immersion bath and the immersion bath liquid, contained in them, is poured out. The hollow bodies, so coated, are carried at a distance from each other to a drying kiln, in which they are dried, whereupon they can be printed or labelled.
