  • Patent number: 9228992
    Abstract: The present invention relates to an electric insulating oil inspection method for determining whether or not an inhibitor-consuming substance is present in an electric insulating oil. The inhibitor-consuming substance is such a substance that causes to decrease over time a concentration of an inhibitor which is added to the electric insulating oil to inhibit copper sulfide from being generated on an insulating paper immersed in the electric insulating oil. The electric insulting oil inspection method includes steps of: preserving the electric insulating oil at a predetermined condition, measuring a concentration of the inhibitor, and determining that the inhibitor-consuming substance is present upon condition that a decrement of the concentration of the inhibitor relative to an initial concentration of the inhibitor becomes not less than a specified amount within a predetermined period.

    Abstract: A dielectric fluid composition for electrical apparatus comprises a functionalized 12-hydroxy stearic acid having desirable properties including a pour point less than ?30° C. and a fire point greater than 250° C. It may be prepared by a process wherein 12-hydroxy methyl stearate is transesterified by reaction with a C3-C20 alcohol to form an alkyl-12-hydroxy stearate, followed by esterification thereof with a linear or branched C4-C20 carboxylic acid. This acid may be a free acid chloride, a fatty acid, a carboxylic acid anhydride, or combination thereof. The resulting functionalized 12-hydroxy stearic acid exhibits improved thermoxidative capability, low temperature flowability, and increased fire point.

    Abstract: Provided are a method of fabricating an electrophoretic ink, the electrophoretic ink formed using the method, and an electrophoretic display having the same. The method of fabricating the electrophoretic ink includes dispersing a pigment particle into a dielectric fluid for the electrophoretic ink and adding at least monomer and initiator to the dielectric fluid to form a polymeric membrane surrounding the pigment particle. Since the pigment particle surrounded by the polymeric membrane and the dielectric fluid in which the pigment particle is dispersed can be utilized as the electrophoretic ink as they are, the method of fabricating the electrophoretic ink is simplified.

  • Patent number: 6726857
    Abstract: The present invention comprises a mixture of hydrocarbons having a well-defined chemical composition that is suitable for use as a dielectric coolant in electrical equipment in general, and specifically in transformers. The dielectric coolants of the present invention are particularly suited for use in sealed, non-vented transformers, and have improved performance characteristics, including decreased degradation of the paper insulating layers, as well as a greater degree of safety and environmental acceptability. The present dielectric coolants comprise relatively pure blends of compounds selected from the group consisting of aromatic hydrocarbons, polyalphaolefins, polyol esters, and natural vegetable oils, along with additives to improve pour point, increase stability and reduce oxidation rate.

  • Publication number: 20020108847
    Abstract: A sputter transport device comprises a sealed chamber, a negatively-biased target cathode holder disposed in the chamber, and a substrate holder disposed in the chamber and spaced at a distance from the target cathode. A target cathode is bonded to the target cathode holder. A magnetron assembly is disposed in the chamber proximate to the target cathode. A negatively-biased, non-thermionic electron/plasma injector assembly is disposed between the target cathode and the substrate holder. The injector assembly fluidly communicates with a gas source and includes a plurality of hollow cathodes. Each hollow cathode includes an orifice communicating with the chamber. The device can be used to produce thin-films and ultra-thick materials in polycrystalline, single-crystal and epitaxial forms, and thus to produce articles and devices that are useful as metallic or insulating coatings, and as bulk semiconductor and optoelectronic materials.

  • Patent number: 5871673
    Abstract: An uninflammable insulating liquid is obtained by adding an emulsifying agent having a volume ratio of 1 to 3% to an insulating liquid containing a fluorocarbon liquid of at least 25% in a volume ratio to cause emulsification. In this liquid mixture, when polyol ester or polydimethylsiloxane is used as the insulating liquid, an uninflammable insulating liquid that does not cause pollution or an environmental problem can be obtained. When tricresyl phosphate is used as the insulating liquid, an uninflammable insulating liquid having a dielectric constant close to that of insulating paper can be obtained. A liquid pipe for circulating a fluorocarbon emulsion in a tank is provided outside the tank, and a pump and a stirrer are connected midway along the liquid pipe to constantly stir the fluorocarbon emulsion, thereby preventing it from being separated into two layers. When a radiator is provided to the liquid pipe, the stirring system for the fluorocarbon emulsion can also serve as the cooling system.
