Publication number: 20040110357Abstract: A method for manufacturing a multilayer ceramic capacitor includes the steps of forming a ceramic slurry, forming ceramic green sheets from the ceramic slurry, printing internal electrode patterns on the ceramic green sheets, generating a laminated body by stacking the ceramic green sheets provided with the internal electrode patterns printed thereon, dicing the laminated body to thereby form chip-shaped ceramic bodies and sintering the chip-shaped ceramic bodies. The ceramic slurry includes a glass component containing one or more additive elements selected from the group consisting of Mn, V, Cr, Mo, Fe, Ni, Cu and Co.Type: ApplicationFiled: November 6, 2003Publication date: June 10, 2004Inventors: Hirokazu Chazono, Hisamitsu Shizuno, Hiroshi Kishi

Patent number: 6740363Abstract: Provided is a method to produce high-temperature lubricious glassy films on silicon-based ceramics. The method comprises the steps of (a) oxidizing a silicon-based component, (b) coating the oxidized component with an alkali metal compound, and (c) heating the component to a high temperature in a sulfur-rich oxidizing environment. The steady state sliding friction coefficient values obtained with this system in 600° C. air are similar to those obtained with liquid lubricants operating under boundary lubrication conditions at much lower temperatures.Type: GrantFiled: April 17, 2003Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Lewis Rosado

Publication number: 20040095049Abstract: A method for manufacturing a starting element, in particular a sheathed-element glow plug, for the combustion process in an internal combustion engine having a ceramic element (1, 3) is proposed, which substantially improves the glazing of the ceramic element (1, 3). According to the present invention, this is achieved by a dry glaze (2) being applied on the ceramic element (1, 3).Type: ApplicationFiled: December 16, 2003Publication date: May 20, 2004Inventors: Heinz Geier, Eckhardt Kuglin, Michael Hausser, Herbert Triptrap

Publication number: 20040086648Abstract: A metal oxide layer can be deposited onto metallic or ceramic surfaces of a structure in situ, by exposing the surfaces to a precursor solution at an elevated temperature. The precursor solution contains: an organometallic, an oxidant, a surfactant, a chelating agent and water. The precursor solution is injected into the structure and maintained at a specific temperature, pH level and pressure for a predetermined period of time. The resulting in situ metal oxide layer is permanently bonded to the surface structure and does require post deposition heat treatment.Type: ApplicationFiled: June 11, 2003Publication date: May 6, 2004Inventors: Xiangyang Zhou, Zhuang Fei Zhou, Serguei N. Lvov, Digby D. MacDonald

Publication number: 20040086652Abstract: A method of manufacturing a glazing panel comprises the steps of: a) taking a glazing panel having on one of its surfaces (i) a substantially transparent coating layer having a transformable portion, and (ii) an enamel material associated with the transformable portion of the coating layer; and b) causing an interaction between the transformable portion of the coating layer and the enamel material associated therewith by healing the glazing panel to a temperature above about 300° C. This may render a portion of the coating layer less susceptible to corrosion and/or non-conductive to electricity.Type: ApplicationFiled: April 16, 2003Publication date: May 6, 2004Inventor: Etienne Degand
