A thin film capacitor with high capacity and low leak current is provided. The thin film capacitor includes a nickel substrate with nickel (Ni) purity of 99.99 weight percent or above, and a dielectric layer and an electrode layer disposed in this order on the nickel substrate. The thin film capacitor is typically manufactured as follows. A precursor dielectric layer is formed on a nickel substrate with nickel purity of 99.99 weight percent or above, and is subjected to annealing to form a dielectric layer. The diffusion of impurities from the nickel substrate to the precursor dielectric layer during annealing is suppressed.

The present invention relates to a copper-containing formulation for plant disease-control which comprises divalent copper and polyphosphate residues, wherein the amount of the polyphosphate residues per one chemical equivalent of the divalent copper is higher than one chemical equivalent. The copper-containing formulation of the present invention shows an excellent disease-control effect without causing any chemical injury of the plant.
Abstract:
A method of producing a magnetic garnet single crystal film formation substrate 2 for growing a magnetic garnet single crystal film by liquid phase epitaxial growth is provided. First, a base substrate 10 composed of a garnet-based single crystal being unstable with a flux used for the liquid phase epitaxial growth is formed. Next, a buffer layer 11 composed of a garnet-based single crystal thin film formed at least on a crystal growing surface of said base substrate 10 and being stable with the flux is formed. When forming the buffer layer 11 on the base substrate 10, it is formed by a thin film formation method, such as sputtering, without heating the substrate 10 in a positive manner.

Abstract:
A sliding part of a magnetic-field generator is configured to slide above and spaced from a surface of a loaded magneto-optical disk in a floating manner. A magnetic-field generating part, which provides a magnetic field to the magneto-optical disk, includes a magnetic pole disposed on a side of the sliding part such that the magnetic pole and the sliding part are positioned adjacent to each other in a radial direction of the surface of the loaded magneto-optical disk and such that the magnetic pole is located closer to a periphery of the magneto-optical disk than the sliding part. An entire flat end surface of the magnetic pole confronting the surface of the magneto-optical disk is generally parallel to and recedes from a slide surface of the sliding part such that the entire flat end surface is spaced further from the surface of the magneto-optical disk than the slide surface of the sliding part.

Abstract:
A ceramics composite material containing crystallized glass as the matrix and fibers or whiskers of ceramics as a reinforcement material, is obtained by melting original glass to form crystallized glass, compounding the same with fibers or whiskers of oxide ceramics and thereafter crystallizing the original glass. This ceramics composite material does not form any voids and can easily contain at least 50 volume percent of the reinforcement material, whereby a good mechanical strength and fracture toughness are achieved. In the compounding step, the content of the reinforcement can be further increased by forcing out any excess part of the original glass from the reinforcement material by applying pressure to a substance obtained by mixing the original glass with the reinforcement. Further, the ceramics composite material can be efficiently formed into a desired configuration by heating because the original glass flows viscously.
