Abstract: Quinoline derivatives represented by formula (1) wherein two or more of substituents R1 to R7 are each a group of formula (2). In general formula (2), Q is a carbo- or hetero-aryl group; and the number (n) of double bonds is preferably 1 to 3.

Optionally, certain embodiments of this invention relate to coated articles that also have high visible transmission and/or good durability.

A powder can be placed within the inner cavity having an average primary particle size of less than about one micron. The powder can be in the form of an unagglomerated particles or a powder coating with a degree of agglomeration or hard fusing ranging from none to significant amounts as long as the primary particles are visible in a micrograph.

In other embodiments, a powder coating is formed within a preform structure by depositing the powder coating directly from a reaction product stream. The formation of the powder coating can be formed within the reaction chamber or outside of the reaction chamber by flowing the product particle stream through a conduit leading to the preform structure. In additional embodiments, a powder coating is placed on an insert, e.g.

Abstract: This invention relates to the nature of thick film compositions that are specifically designed for the fabrication of circuit elements on diamond substrates, especially resistive elements. The nature of diamond sheet material requires special consideration because of its relatively low coefficient of thermal expansion and its sensitivity to oxygen at elevated processing temperatures. The general compositional requirements of thick film paste formulations are provided as a basis for accommodating the particular physical properties of diamond, and thereby establishing a method by which high performance microelectronic components can be fabricated economically. Thick film pastes containing certain borosilicate glasses, metal components, and optionally semiconducting materials are demonstrated to possess favorable behavior in terms of mechanical and electrical properties after sintering. Resistive elements on diamond can be fabricated by adding conductive components to a borosilicate glass.

Abstract: A dielectric element employing an oxide-based dielectric film capable of suppressing oxidation of an electrode or deterioration of film characteristics of the oxide-based dielectric film is obtained. This dielectric element comprises an insulator film including the oxide-based dielectric film and the electrode including a first conductor film containing at least a metal and silicon. The aforementioned metal includes at least one metal selected from a group consisting of Ir, Pt, Ru, Re, Ni, Co and Mo. Thus, the aforementioned first conductor film serves as a barrier film for stopping diffusion of oxygen. In heat treatment for sintering the oxide-based dielectric film, therefore, oxygen is effectively inhibited from diffusing along grain boundaries of the electrode. Consequently, a conductive material located under the electrode can be inhibited from oxidation.
