Abstract: A composite laminate ceramic electronic component that includes co-fired low dielectric constant ceramic layers and high dielectric constant ceramic layers. The low dielectric constant ceramic layers and high dielectric constant ceramic layers are each composed of a glass ceramic containing: a first ceramic composed of at least one of MgAl2O4 and Mg2SiO4; a second ceramic composed of BaO, RE2O3 (RE is a rare earth element), and TiO2; glass containing each of 44.0-69.0 wt % of RO (R is an alkaline-earth metal), 14.2-30.0 wt % of SiO2, 10.0-20.0 wt % of B2O3, 0.5-4.0 wt % of Al2O3, 0.3-7.5 wt % of Li2O, and 0.1-5.5 wt % of MgO; and MnO. The content ratios of the first ceramic, second ceramic, glass, and MnO are varied between the low dielectric constant ceramic layers and the high dielectric constant ceramic layers, wherein the content of MnO in the low dielectric constant ceramic layers is 7.5-18.5 wt % MnO.

Abstract: An article is coated with a coating having a dark color. In a preferred embodiment, the coating comprises a nickel or polymer basecoat layer, a first metal oxycarbide color layer comprised of 15 atomic percent carbon, 25 to 30 atomic percent oxygen, and 55 to 60 percent atomic percent refractory metal, a second metal oxycarbide color layer comprised of 10 atomic percent carbon, 50 to 60 atomic percent oxygen, and 30 to 40 atomic percent refractory metal, and a top layer of refractory metal oxides.

Abstract: An ornamental structure for a vehicle upholstery member provides a plurality of surface patterns by using a single vehicle upholstery member. On the surface of an embossed vehicle upholstery member are arranged a first region formed with a first emboss pattern, a second region spaced from the first region and formed with a second emboss pattern different from the first emboss pattern, and a third region located between the first and second regions and formed with a third emboss pattern which changes progressively from the first emboss pattern to the second emboss pattern as one moves from the first region to the second region.

Abstract: A display window is formed by mechanically processing a transparent ceramic article. The composition of the ceramic article includes yttrium oxide and thorium oxide, the mole percentage of yttrium oxide is about 85% to about 94.99%, and the mole percentage of thorium oxide is about 4.99% to about 15%. The display window has a high light transmittance, good acid and alkali corrosion resistance, high hardness, long lifetime.
