    Abstract: When a conductive layer is formed, a first liquid composition containing a conductive material is applied on an outer side of a pattern that is desired to be formed (corresponding to a contour or an edge portion of a pattern), and a first conductive layer (insulating layer) having a frame-shape is formed. A second liquid composition containing a conductive material is applied so as to fill a space inside the first conductive layer having a frame-shape, whereby a second conductive layer is formed. The first conductive layer and the second conductive layer are formed so as to be in contact with each other, and the first conductive layer is formed so as to surround the second conductive layer. Therefore, the first conductive layer and the second conductive layer can be used as one continuous conductive layer.

  • 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.

  • Patent number: 7354733
    Abstract: We disclose methods of sorting or separating mixtures of living cells (e.g., eukaryotic, prokaryotic, mammalian, pathogenic, bacterial, viral, etc.). We perform our methods by activating cell-selective photophoric labels, which photosensitize and chemically reduce a photosensitive metal compound to form metal grains, particles or crystals. The metal adheres to the cells and forms the basis for sorting or separating different cell types. Photophoric labels may include chemiluminescent agents such as peroxidase enzymes activated with peroxidase substrates capable of luminescence. Photosensitive metal compounds may be present in a light-sensitive matrix or emulsion containing photosensitizable metal compounds, which form metal grains, particles or crystals upon exposure to a developer solution. Developer solutions are formulated to substantially allow living cells to remain viable after exposure to the developing solution.

  • Patent number: 5098740
    Abstract: Solids that are subject to a deleterious reaction with a dispersion medium in which they are suspended can be safely comminuted in that dispersion medium by providing therein a surfactant capable of reacting with the solid at a faster rate than the dispersion medium can so react to thereby suppress the deleterious reaction. In particular, unsintered silicon nitride or silicon carbide which when contacted with water would decompose to form silica on their surfaces can be milled in water, without producing excessive amounts of silica. The dispersions produced are sufficiently stable to be filtered through openings of 2 microns with loss of no more than 5% of the silicon nitride or carbide. Stable dispersions of solids in liquids can be coated with a different solid by surface precipitation under conditions which preclude the formation of a bulk precipitate.

  • Patent number: 4897283
    Abstract: A highly aligned rare-earth transition metal alloy magnet material such as samarium-cobalt (SmCo.sub.5). The high degree of alignment is evidenced by an isolated X-ray diffraction pattern peak for Cu.sub.k.alpha. radiation at a interplane "d" spacing of 2.0 A.degree. and is produced by very high temperature deposition of the material on a hot surface. The surface temperature is maintained well above 800 degrees centigrade and most preferably is initially set at approximately 1020 degrees centigrade or higher at which temperature the isolated diffraction pattern peak dominates. A higher temperature typically occurs during deposition. Deposition of the material on the surface typically takes place by application of the material as a fine, homogeneously sized powder to the plasma flame of a plasma torch. The surface may be preheated by the application of the plasma flame to the surface without the application of the powdered material.

    Abstract: A process for deposition of a wear-resistant coating onto a cutting tool made from a carbon-containing material by condensation of a substance by bombardment with ions of a cathode material evaporated in a vacuum chamber by means of an arc discharge, wherein prior to placing the cutting tool into the vacuum chamber it is immersed into a saturated solution of a salt, kept therein for 5 to 10 min and the solvent is evaporated till crystallization of the salt on the cutting tool surface occurs; heating of the cutting tool by ion bombardment is effected first to the temperature of decomposition of the salt crystals, whereafter the arc discharge is switched-off, the cutting tool is kept for 15 to 30 seconds, the arc discharged is re-energized and the heating is continued to the temperature of carbidization of the evaporated cathode material.

  • Patent number: 4384980
    Abstract: A composition is described comprising at least two co-crystallized acetylenic compounds, of different chemical structures, each containing at least one --C.tbd.C--C.tbd.C-- group and substituents selected from the group consisting of sulfonate, urethane and alcohol radicals, at least one of the compounds capable of ungergoing a contrasting color change upon exposure to actinic radiation or thermal annealing, wherein the composition exhibits a substantially different thermogram than the sum of thermograms of the individual components as obtained by differential scanning alorimetry.A device is also described useful for measuring the time-temperature or radiation-dosage history of an article comprising a substrate having deposited thereon the described composition.A process is also described for producing the composition of this invention.

  • Patent number: 4324819
    Abstract: A catalyst is provided for decomposing hydrazine base monopropellants and providing multiple hydrazine-ignition restarts. The catalyst comprises a carrier material selected from the group consisting of high area ceramics, and 1/2 to 8% of active iridium, ruthenium, or mixtures thereof, based on the total weight of the catalyst. The active metal is deposited primarily on the exterior surface of the carrier. A second metal catalyst can be contained primarily within the interior of the carrier.The method of producing the catalyst comprises impregnating the carrier with an alcohol solution containing a salt of iridium, ruthenium, or a mixture thereof, to deposit the metal on the exterior surface only of the carrier. The precious metal is reduced to an active pure metal by contact with a fluid reducing agent selected from the group consisting of hydrogen and hydrogen-inert gas mixtures.

  • Patent number: 4209008
    Abstract: Photon absorbing surfaces which are effective over a broad band of photon energies are described. These surfaces consist of a two-phase material with a protruding second phase whose dimensions are on the order of microns. Photons are absorbed by multiple reflections within the region of the protruding phase. The surfaces are produced by directional solidification of eutectic compositions to produce aligned second phase microstructures within a metallic matrix. The matrix material is then selectively removed to expose the second phase material.

  • Patent number: 4172160
    Abstract: A texturized coating applied to one or both surfaces of bare or prepainted metal coil or sheet protects the surface against damage before, during, and after fabrication. The coating consists essentially of a thermosetting resin vehicle and a high molecular weight, hard, paraffin wax which, when cured, at a temperature greater than the melting point of said wax provides a reduced surface contact area of lubricating beads high in wax content.
