  • Patent number: 7998601
    Abstract: A method produces thermal barrier coatings that adhere to components even at high temperatures and temperatures that change frequently. A gas-tight glass-metal composite coating is applied to the component and annealed. The corroded part of the gas-tight coating is then removed, and a second, porous coating is applied. The second coating can comprise a ceramic, in particular yttrium-stabilized zirconium oxide. A thermal barrier coating is provided that is a composite made of a gas-tight glass-metal composite coating and another porous coating disposed thereover. Because the boundary volume of the composite coating is partly crystallized to the other coating, superior adhesion within the composite is achieved. Thus, it is in particular possible to produce a composite made of silicate glass-metal composite coatings and yttrium-stabilized zirconium oxide that are temperature-stable for extended periods of time.

    Abstract: After forming an opening, a resist film is formed on the entire surface and a resist pattern is formed by patterning the resist film. The shape of the resist pattern is such that it covers one side of the bottom of the opening. As a result, a Si substrate is exposed only in one part of the opening. Then, using the resist pattern as a mask, a catalytic layer is formed on the bottom of the opening. Then, the resist pattern is removed. Carbon nanotubes are grown on the catalytic layer. At this time, since the catalytic layer is formed on only one side of the bottom of the opening, the Van der Waals force biased towards that side works horizontally on the growing carbon nanotubes. Therefore, the carbon nanotubes are attracted towards the nearest side of the SiO2 film and grow biased towards that side.

    Abstract: A direct-write method for fabricating magnetic nanostructures, including hard magnetic nanostructures of barium hexaferrite, BaFe, based on nanolithographic printing and a sol-gel process. This method utilizes a conventional atomic force microscope tip, coated with a magnetic material precursor solution, to generate patterns that can be post-treated at elevated temperature to generate magnetic features consisting of barium ferrite in its hexagonal magnetoplumbite (M-type) structure. Features ranging from several hundred nm down to below 100 nm were generated and studied using AFM, magnetic force microscopy, and X-ray photoelectron spectroscopy. The approach offers a new way for patterning functional inorganic magnetic nanostructures with deliberate control over feature size and shape, as well as interfeature distance and location.

  • Patent number: 6866883
    Abstract: A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate having at least one surface; forming a layer of a sol-gel on the surface, partially drying the sol-gel layer at room temperature to remove a portion of the solvent therein to form a partially dried sol-gel layer of hardness less than that of the substrate; mechanically texturing the surface of the partially dried sol-gel layer; and depositing a layer stack including at least one magnetic layer thereover. Embodiments of the invention include embossing a servo pattern in the as-deposited sol-gel layer prior to partial drying and mechanically texturing, followed by sintering at an elevated temperature to form a substantially fully dried layer having a density and hardness similar to that of glass, and formation of a thin film magnetic media layer stack thereon.

  • Patent number: 6742360
    Abstract: In a sealing apparatus used in a process for sealing a glass tube-assembly of a flat-type cathode-ray tube by frits, three of a front panel, a screen panel and a funnel can be sealed together, and the front panel can be prevented from being broken. The sealing apparatus includes a frame for properly positioning a combined assembly in which the front panel, the screen panel and the funnel are butted with each other by frits and the following sealing jig (41). The sealing jig (41) includes a holding means (42) for holding a front panel (2) and a screen panel (3) under the condition that joint surfaces of the front panel and the screen panel are butted with each other by frits. The holding means (42) is provided with a first resilient member (43) which is urged against the outer surface of the front panel (2) and a second resilient member (42) which is urged against the outer surface of the screen panel (3).

  • Publication number: 20040081760
    Abstract: A ceramic thermal barrier coating (46) having a plurality of segmentation gaps (44) formed in its top surface (56) to provide thermal strain relief. The surface width of the gaps may be limited to minimize the aerodynamic impact of the gaps. The gaps may be formed as continuous grooves (68) extending along a flow path of a fluid stream traveling over the thermal barrier coating. Such grooves may be used in the fluid stream without removing the ridge (60) created by splashing of molten material onto the surface of the coating during a laser engraving process used to form the grooves, since the fluid stream is flowing parallel to the ridge. Preferred failure planes (A1, A2, A3) may be formed through the thickness of the coating in order to stimulate the generation of a fresh surface when a portion of the coating fails by spalling. The bottom geometry of the gaps may be formed to have a generally U-shape in order to minimize stress concentration.

  • Patent number: 6716539
    Abstract: A multi-layer thermal barrier coating (12) having a porous first layer of ceramic insulating material (20) and a second relatively dense layer of ceramic insulating material (22) having a plurality generally vertical gaps (26) formed therein. The porous conventional as-deposited APS microstructure of the first layer provides thermal and chemical protection for the substrate, while the gaps of the columnar-grained second layer provide thermal shock resistance for the coating. An air plasma spray process may be used to deposit both the first and the second layers of material, as well as any underlying bond coat layer. The gaps of the columnar-grained second layer do not extend into the first layer. The pores (28) of the first layer function as crack-arrestors for cracks initiating at the gaps of the second layer.

  • Patent number: 6673390
    Abstract: A method for manufacturing a touch screen linearization pattern which is necessary for a five wire resistive type or current sensing type touch screen, and directly affects the accuracy, production price, and border area size of the touch screen, includes the steps of printing a linearization pattern on the border area of a conductive glass surface with a selected ink. The ink is made by blending highly conductive silver powder between about 59% to 62% in weight and carbon powder between about 14% to 16% in a contact agent solvent between about 24% to 25% in weight. The touch screen thus formed has a resistance value ratio of about ten between the square surface of the glass layer and the two ends of the linearization pattern.
