A method of forming a diamond-like carbon film on a substrate arranged in a vacuum chamber includes the steps of generating an arc-discharge plasma current in the vacuum chamber, supplying a reaction gas containing carbon atoms, such as CH.sub.4 gas for example, into the arc-discharge plasma current, applying a high-frequency voltage to the substrate so that a self-bias developed in the substrate is not more than -200 V, and forming a diamond-like carbon film from the reaction gas on the substrate that is supplied with the high-frequency voltage.
摘要:
A production process for an oxide magnetic material comprising the steps of blending raw material powder so as to take the composition of a hexagonal ferrite including: at least one kind of an element A selected from the group consisting of Ba, Sr and Ca; Co and Cu; Fe; and O; and sintering said blended powder at a temperature lower than 1000° C.

摘要:
A sliding member having a sliding surface for sliding contact with a cooperative member is disclosed. A protective film is deposited not only on the sliding surface but also a surface region immediately adjacent the sliding surface such that a ratio d1/d2 is controlled to be 1 or greater, where d1 is a thickness of the protective film on the sliding surface and d2 is a thickness of the protective film on the surface region immediately adjacent the sliding surface. Alternatively, the protective film is deposited at least on the sliding surface such that the protective film is varied in thickness to define an irregular top surface.

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.
摘要:
A hard carbon thin film formed on a substrate has a graded structure in which a ratio of sp.sup.2 to sp.sup.3 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 thin film magnetic head includes a magnetoresistive element portion movable over and relative to a magnetic recording medium for reading information stored therein, upper and lower shielding layers disposed with the magnetoresistive element portion therebetween for magnetically shielding the magnetoresistive element portion, and upper and lower gap insulative layers respectively interposed between the upper shielding layer and the magnetoresistive element portion and between the lower shielding layer and the magnetoresistive element portion. Each of the upper and lower gap insulative layers includes a hydrogen-incorporated film. The upper gap insulative layer has an increased hydrogen content and a reduced internal stress relative to the lower gap insulative layer.
摘要:
A hard-carbon-film-coated substrate includes in stacked sequence a substrate, an intermediate layer, and a hard carbon film. The substrate consists of a metal or an alloy mainly composed of Ni or Al, or stainless steel. The intermediate layer is mainly composed of Ru, Si, Ge or carbon, or is a mixed layer including Ru, Si, or Ge mixed with at least one of carbon, nitrogen or oxygen, with a composition gradient across its thickness. An apparatus for forming the coated substrate especially includes means for forming the intermediate layer and means for forming the hard carbon film in the same vacuum chamber.
摘要:
The body of a micromachine has a plurality of energy-power converting means for receiving different forms of energy including rays, microwaves and sound waves and converting the different forms of energy to electric power, i.e., photoelectromotive devices, a microwave-power converter and an acousto-electromotive device. The electric power obtained by these means is supplied to a drive system and an operation system incorporated in the machine body.
