摘要:
A pre-curing viscous solution (precursor solution) is applied to the back surface of a substrate for forming an optically transparent layer principally composed of an inorganic material. The substrate is heated or irradiated with UV light while being pressed with unevenness of a mold. By removing the substrate from the mold, the optically transparent, inorganic material layer principally composed of the inorganic material is formed on the substrate. In this manner, the inorganic material layer with the unevenness is formed on the back surface of the substrate (a light extraction surface) by embossing.
摘要:
A hard carbon thin film formed on a substrate has a graded structure in which a ratio of sp2 to sp3 carbon-carbon bonding in the thin film decreases in its thickness direction from a thin film/substrate interface toward a surface of the thin film. A method of forming the thin film involves varying the film-forming ion species over time to produce the composition gradient or structural gradient in the thickness direction of the thin film.

The disclosed method of forming a high-function material film such as a ZrN thin film on a substrate in a vacuum chamber allows the color tone and uniformity of the film to be controlled. Gaseous nitrogen and gaseous oxygen, or nitrogen ions and oxygen ions, are supplied to the substrate while hard material atoms such as Zr atoms are emitted from an evaporation source toward the substrate. A supply partial pressure of the gaseous oxygen is set at a value within a range from about 10.sup.-5 Torr to about 10.sup.-4 Torr.
摘要:
An organic-inorganic composite material is formed by polycondensating a metal alkoxide through hydrolysis until the unreacted metal alkoxide is reduced to 3 vol. % or less, and mixing it with an organic polymer. The composite material has a light transmittance of at least 90% per 10 μm material thickness for light of 600 to 1000 nm. The metal element content of the composite material is preferably 0.1 to 46 wt. %, more preferably 5 to 37 wt. %. By laminating layers of such organic-inorganic composite materials having respective different compositions, the resulting laminate has a concentration gradient wherein the metal element content increases or decreases monotonously, or increases and decreases in succession, from one side to the other side of the laminate. The resulting refractive index varies opposite the metal element content. The material can be used for an optical waveguide or a light transmission structure.

A composite magnetic material contains first magnetic particles made of a first magnetic material and second magnetic particles made of a second magnetic material, the first and second magnetic particles being mixed with each other. A frequency characteristic of the first magnetic material is different from that of the second magnetic material. The first and second magnetic particles are mixed so that, at a frequency of an intersecting point between a first curve representing a frequency characteristic of a real part of a complex magnetic permeability of the first magnetic material and a second curve representing a frequency characteristic of a real part of a complex magnetic permeability of the second magnetic material, a value of a real part of a complex magnetic permeability of the composite magnetic material is larger than a value of the intersecting point.

摘要:
A member is disclosed which includes a hard carbon film provided through an interlayer or directly on a main body such as a vane. A mixed layer is formed within the main body or interlayer adjacent to an outer surface of the main body or interlayer. The mixed layer contains carbon and a constituent element of either the main body or the interlayer. The mixed layer has a carbon content gradient in its thickness direction so that a carbon content in a thickness portion thereof closer to an outer surface of the mixed layer is higher than in a thickness portion thereof remoter from the outer surface of the mixed layer.
