  • Patent number: 8383195
    Abstract: In a production method for a laminated electronic component, a ceramic base body is formed by stacking a plurality of ceramic layers, and internal electrodes are formed in the ceramic base body. Lead-out portions of the internal electrodes are exposed from side surfaces of the ceramic base body. Belt-shaped external terminal electrodes are formed on the side surfaces by plating so as to be electrically connected to the exposed portions of the internal electrodes. The distance from an end surface to an external terminal electrode closest to the end surface in the ceramic base body is measured. When the measured distance does not correspond to a predetermined reference value, the ceramic base body is removed as being defective.

  • Publication number: 20130045328
    Abstract: High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The preferred manufacturing process involves the initial oxidation of the carbon nanostructures followed by a surface preparation process involving immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing a suitable quantity of non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means. The nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. The process can be controlled and repeated to obtain a desired film coverage.

  • Patent number: 8197886
    Abstract: The present invention provides a method of manufacturing a solid electrolytic capacitor including a step of forming a conductive polymer layer by chemical oxidization polymerization of a monomer using a solution containing a metal salt of carbon-fused bicyclic sulfonic acid as an oxidizing agent. The molar ratio X of a carbon-fused bicyclic sulfonate ion to a metal ion in the solution is less than the stoichiometric ratio Y of the metal salt of carbon-fused bicyclic sulfonic acid. This is allowed to provide a solid electrolytic capacitor with a sufficiently low equivalent series resistance (ESR) and high heat resistance.

  • Patent number: 8178155
    Abstract: A method of manufacturing a high surface area per unit weight carbon electrode includes providing a substrate, depositing a carbon-rich material on the substrate to form a film, and after the depositing, activating the carbon-rich material to increase the surface area of the film of carbon-rich material. Due to the activation process being after deposition, this method enables use of low cost carbon-rich material to form a carbon electrode in the capacitor. The electrode may be used in capacitors, ultracapacitors and lithium ion batteries. The substrate may be part of the electrode, or it may be sacrificial—being consumed during the activation process. The carbon-rich material may include any of carbonized material, carbon aerogel and metal oxides, such as manganese and ruthenium oxide. The activation may include exposing the carbon-rich material to carbon dioxide at elevated temperature, in the range of 300 to 900 degrees centigrade.

  • Publication number: 20120099240
    Abstract: A magnetic capacitor includes two electrode layers, an insulator layer, and one or more magnetized layers. The insulator layer is located between the first electrode layer and the second electrode layer. The one or more magnetized layers include one or more ferro-magnetic elements that are magnetized. The one or more magnetized layers are located so that the one or more ferro-magnetic elements apply a magnetic field to the insulator layer to improve an electrical property of the insulator layer. Magnetic fields applied perpendicular to the electrode layers increase the capacitance and electrical energy storage of the insulator layer. Magnetic fields applied parallel to the electrode layers decrease the leakage current and increase the breakdown voltage of the insulator layer. The one or more ferro-magnetic elements used can include ferro-magnetic plates or magnetic nanodots. The one or more magnetized layers can be located between or outside of the electrode layers.
