  • Patent number: 10435591
    Abstract: An adhesive tape substrate production method disclosed in the present description includes the steps of: decreasing the amount of a sizing agent contained in a glass cloth by heat; impregnating the glass cloth for which the amount of the sizing agent has been decreased with a dispersion of a fluorine resin; and heating the impregnated glass cloth to a temperature equal to or higher than a melting point of the fluorine resin. Thus, an adhesive tape substrate including the glass cloth impregnated with the fluorine resin is obtained. This method are more productive of adhesive tape substrates and adhesive tapes than conventional methods. In addition, adhesive tape substrates and adhesive tapes for which the occurrence of defects in appearance are reduced can be produced.

    Abstract: A surface treatment device that ejects a combination of precursor substances as a directed flow of surface treatment particles. Planar objects are conveyed along a defined plane through the particle flow, a region on the surface of the planar object that the particle flow hits forming a region of direct impact. The device comprises directing means for directing the particle flow to travel along the surface of the planar object in an extended impact region outside the region of direct impact; and flow control means for controlling the extent of the extended impact region which may include a vortex flow. The exposure of the treated surface with the particle flow increases and the probability of the desired surface treatment processes to take place increases.

  • Publication number: 20100330273
    Abstract: A substrate coated with a coating solution for an anti-reflective film is placed on a heat treatment plate and is heated. Nitrogen gas flows near the periphery of the heat treatment plate into a heat treatment space. An exhaust outlet is formed in an upper central portion of an inner cover, and the inner cover has an inner wall surface configured in the form of a tapered surface. This produces a smooth flow of nitrogen gas along the tapered surface to smoothly discharge a sublimate produced from the coating solution together with the gas flow outwardly through the exhaust outlet. After the heating process for a predetermined period of time is completed, the cover moves upwardly, and support pins move upwardly to thrust up the substrate from the heat treatment plate, thereby spacing the substrate apart from the heat treatment plate. This gradually decreases the temperature of the substrate.

  • Patent number: 7803424
    Abstract: A method for manufacturing a metal-carrying carbonaceous material is provided. The method comprises immersing a carbonaceous material in a metal-containing aqueous solution under vacuum, with stirring, and/or in the presence of a polar solvent, and then thermally treating the immersed carbonaceous material at a temperature ranging from 120° C. up to a temperature not higher than the melting point of the involved metal under vacuum or in the presence of a protective gas. According to the method, the metal can be effectively carried on a carbonaceous material so as to enhance the applicability of the metal-carrying carbonaceous material.

  • Patent number: 7781024
    Abstract: The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun. The energy for creating a layer on a substrate is produced by injecting a powerful kinetic energy into the cold gas stream, thus preventing or significantly restricting the thermal heating of the cold gas stream. This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced.

  • Publication number: 20100189991
    Abstract: A method is disclosed to fabricate carbon foams comprising a bicontinuous network of disordered or irregular macropores that are three-dimensionally interconnected via nanoscopic carbon walls. The method accounts for (1) the importance of wetting (i.e., matching the surface energies of fiber to sol) and (2) the viscosity of the microheterogeneous fluid filling the voids in the carbon paper. Carbon fiber papers are mildly oxidized by plasma etching, which greatly enhances the uniform uptake of resorcinol-formaldehyde (RF) mixtures.

  • Patent number: 7666463
    Abstract: Methods for manufacturing porous nuclear fuel elements for use in advanced high temperature gas-cooled nuclear reactors (HTGR's). Advanced uranium bi-carbide, uranium tri-carbide and uranium carbonitride nuclear fuels can be used. These fuels have high melting temperatures, high thermal conductivity, and high resistance to erosion by hot hydrogen gas. Tri-carbide fuels, such as (U,Zr,Nb)C, can be fabricated using chemical vapor infiltration (CVI) to simultaneously deposit each of the three separate carbides, e.g., UC, ZrC, and NbC in a single CVI step. By using CVI, a thin coating of nuclear fuel may be deposited inside of a highly porous skeletal structure made, for example, of reticulated vitreous carbon foam.
