Abstract:
A wire harness consists 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 following to the actual wiring route of the electrical wires, so that the assembling property can be improved.

Abstract:
A magneto-optical disk driving apparatus of the magnetic field modulated recording type is generally provided with a magnetic biasing apparatus, which generates a magnetic field required to record or erase information signals on or from a magneto-optic recording medium. The magnetic biasing apparatus includes a magnetic circuit capable of recording or erasing the information signals on or from the magneto-optical recording medium and a slide member bonded to an open end of the magnetic circuit. The slide member is made up of a crosslinked setting resin, one or two lubricants contained in the setting resin, and a filler embedded in the setting resin. One of the lubricants has a linear molecular structure, whereas the other has a branched molecular structure. The filler is made up of a large number of porous particulates having a specific surface of from 100 to 1000 m.sup.2 /g (measured in accordance with the BET equation) and a large number of whiskers having a diameter in the order of submicrons or less.
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.

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.

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.
