Abstract:
When a mixture of gases containing carbon is burned to form a film of diamond on a surface of a substrate held at an appropriate temperature, it is so burned as to form a substantially flat region of incomplete combustion lying in parallel to the substrate surface and contacting it, while the region is surrounded by an air-shielding gas stream or formed under a reduced pressure.
Abstract:
An oxygen sensor element is manufactured by successively forming on the outside of the output lead wire, a solid pole, a first metal electrode layer, a solid electrolyte layer, and a second metal electrode layer from inside to outside.
Abstract:
An oxygen sensor consisting of a metal electrode formed on the surface of the side to be measured of a solid electrolyte sintering and of a reference oxygen pole formed by a mixture of metal and metal oxide on the opposite side of said surface of the side to be measured of the solid electrolyte sintering body, characterized in that, at least over the whole surface adjoining the mixture of metal and metal oxide on the side of the reference oxygen pole of the solid electrolyte sintering, a porous metal electrode is formed to insulate the solid electrolyte sintering from the mixture of metal and metal oxide, thereby improving the low temperature performance and internal impedance characteristics, as well as prolonging the life thereof. A method for manufacturing this sensor is also provided.
Abstract:
It is an object of the invention to provide a process for production of a thin-film capacitor that can simultaneously achieve improved capacity density and reduced leakage current density for barium strontium titanate thin-films. There is provided a process for production of thin-film capacitors that includes a metal oxide thin-film forming step in which an organic dielectric starting material is fired to form a barium strontium titanate thin-film, wherein the firing atmosphere used is an oxygen-containing inert gas atmosphere, and the barium strontium titanate thin-film formed by the process has a larger capacity density than the capacity density of the barium strontium titanate thin-film fired in an oxygen atmosphere.

A capacitor provided with a dielectric film, and a first electrode and second electrode formed sandwiching it and facing each other, wherein the dielectric film has a density exceeding 72% of the theoretical density calculated based on the lattice constant, and either or both of said first electrode and said second electrode contain at least one metal selected from the group consisting of Cu, Ni, Al, stainless steel and inconel.
Abstract:
The object of the present invention is to provide a method of producing antisense oligonucleotide, in which the possibility of forming a substantially complementary double-stranded chain between each region of a nucleotide sequence in mRNA and a region other than said region is expressed as a numerical value, and oligonucleotide substantially complementary to a region with a smaller numerical value is prepared as antisense oligonucleotide. The resulting antisense oligonucleotide can be used effectively in the antisense oligonucleotide method.
Abstract:
A steel has a tensile strength of 850 to 1700 MPa, a yield ratio of at most 80%, and a penetration border energy ratio of at least 2.0 relative to the penetration border energy of a reference steel JIS SS400 (corresponding to ASTM A36) of the same thickness. The steel can be produced by first effecting a heat treatment 1 on an unstable austenitic steel; then effecting, at least once, one or more or any combination of the heat treatment 1 and a heat treatment 2 on the steel; and then finally effecting the heat treatment 2 on the steel. Heat treatment 1 heats the unstable austenitic steel to at least the Ac3 transformation temperature and then water-cools the steel to a temperature below 350° C. Heat treatment 2 heats the steel to a temperature between Ac3 and Ac1 transformation temperatures and then water-cools the steel to a temperature below 350° C.
Abstract:
A clamp plate retaining surface, a handling surface positioned outside the outer circumference of the clamp plate retaining surface, and an information surface outside the outer circumference of the handling surface are provided in a substrate. The handling surface is formed to be a slope with its outer circumferential side being inclined downward with respect to the information surface. The resin forming the inner circumferential side end of the handling surface is melted and deformed to form a projection part, so that a clamp plate can be retained. Since the top part of the slope is deformed, a large projection part can be formed. As a result, a thin small-diameter optical disk and substrate can be obtained.
Abstract:
A high quality magneto-optical disk which has the protective coating being excellent in the lubricity, the property of sliding and a long-term reliability includes a UV-ray resin composition comprising photo polymerizable prepolymer, photo polymerization initiator and organic compound having a side chain of fluoroalkyl group or unsaturated aliphatic alkyl group in the end of each molecule. The UV-ray setting resin comprising photo polymerization prepolymer at 30-80 parts by weight; photo polymerization initiator at 10-40 parts by weight; and organic polysiloxane at 0.1-10 parts by weight per 100 parts by weight of (meth-)acrylic ester is applied to approximately 10 .mu.m on the reflection layer 14 by the spincoat method and irradiating the UV-ray (illuminance: 600 mW/cm.sup.2, quantity of light: 800 mJ/cm.sup.2) at room temperature, thus forming the protective coating.
Abstract:
A wire harness having of electrical wires, a first resin sheet and a second resin sheet. The first resin sheet includes a recess formed so as to extend along a predetermined "three-dimensional" wiring route of the electrical wires. In order to manufacture the wire harness, at first, the recess is formed in the first resin sheet. Then, the electrical wires are arranged in the recess. Next, the second resin sheet is arranged on the first resin sheet so as to cover the recess and air contained in a space defined between the first resin sheet and the second resin sheet is sucked to the outside. Finally, the first resin sheet and the second resin sheet are joined to each other. Owing to the provision of the three-dimensional recess, it is possible to realize the wire harness having a three-dimensional configuration which follows the path actual wiring route of the electrical wires, so that the ease of assembly can be improved.
