    摘要: Diamond clusters are used as a polishing material of free abrading particles, each being a combination of artificial diamond particles having primary particle diameters of 20 nm or less and impurities that are attached around these diamond particles. The density of non-diamond carbon contained in the impurities is in the range of 95% or more and 99% or less, and the density of chlorine contained in other than non-diamond carbon in the impurities is 0.5% or more and preferably 3.5% or less. The diameters of these diamond clusters are in the range of 30 nm or more and 500 nm or less, and their average diameter is in the range of 30 nm or more and 200 nm or less.

The diameters of these diamond clusters are in the range of 30 nm or more and 500 nm or less, and their average diameter is in the range of 30 nm or more and 200 nm or less. Such polishing material is produced first by an explosion shock method to obtain diamond clusters and then removing the impurities such that density of non-diamond carbon contained in the impurities and density of chlorine contained in other than non-diamond carbon in the impurities become adjusted.

    摘要: A target surface of a tape-shaped substrate of an oxide superconductor with an intermediate layer formed on this target surface and an oxide superconductor thin film is polished by causing the tape-shaped substrate to continuously run. The polishing step includes an initial polishing process for carrying out random polishing of the target surface and a finishing process that is carried out after the initial polishing process for forming grooves on the target surface along the running direction of the substrate. The intermediate layer has an in-plane directionality of 7° or less. The tape-shaped substrate is fabricated by rolling nickel, a nickel alloys or stainless steel.

    摘要: An abrasive sheet for precisely abrading a workpiece surface includes an adhesive and an abrading layer made by drying a slurry which is a mixture of abrasive particles and a binder. The abrading layer is preferably of thickness less than about 1.5 times the average size of the abrading particles and has one surface attached to a plastic base sheet through a layer of the adhesive. At least some of the abrading particles in the abrading layer have their end parts at the other surface of the abrading layer which, together with these end parts of the abrading particles, forms a smooth flat abrading surface without irregularly distributed protrusions and indentations.

    摘要: An apparatus for holding a disk with a central hole has a front rod which is received in a chuck so as to be able to move along its axis. The chuck is slidably received between the inner surface of a cylinder and the outer surface of the front rod. The front rod has on its front end an inverted truncated cone of which the maximum outer diameter is smaller than the diameter of the opening in the disk. When a part of the chuck is protruding from the cylinder, the disk can move past a bulge formed on the chuck and positioned on an expander. When the front rod is retracted into the cylinder, the inverted truncated cone moves inside the front end of the chuck so as to spread the chuck until it touches the inner surface of the opening of the disk, and the chuck is retracted along with the front rod so that the disk is firmly grasped and held between the front end of the cylinder and the bulge.
