  • Patent number: 9702444
    Abstract: A method for manufacturing a fluid power transmission includes a first step of assembling a blade/core provisional assembly having a plurality of blades movably linked to a core, involving aligning the plurality of blades on a blade alignment jig, laying the core over a group of blades while extending a projecting piece provided on each blade through a latching hole provided in the core, and bending an extremity part of the projecting piece thus preventing the projecting piece from coming out of the latching hole, a second step of setting the blade/core provisional assembly at a predetermined position on an inside face of the shell, and a third step of carrying out brazing between the projecting piece and the latching hole and between the blade and the shell. Such method provides a high quality impeller of a fluid power transmission by joining a shell, a blade, and a core.

  • Patent number: 8049990
    Abstract: A cleaning tape has a base tape made of a synthetic resin and a cleaning layer formed on a surface of this base tape. The cleaning layer has a binding agent and a large number of spherical particles dispersed in the binding agent in a single particle layer. Such a cleaning tape is capable of removing very small unwanted protrusions and particles on the surface of a target object such as a magnetic hard disk without forming scratches.

  • Patent number: 7857876
    Abstract: 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. 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.

  • Patent number: 7811972
    Abstract: 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.

  • Patent number: 7790046
    Abstract: A method of texturing a surface of a magnetic hard disk substrate includes the steps of rotating the magnetic hard disk substrate, supplying polishing slurry on the surface of the substrate, and pressing a polishing tape on the substrate surface and running the polishing tape. The polishing slurry includes abrading particles of monocrystalline diamond that are cluster particles with corners having diameters in the range of 1-10 nm, dispersed in a dispersant such as water and a water-based aqueous solution. The cluster particles are tasseled assemblies of crystalline particles with no directionality.

  • Patent number: 7631419
    Abstract: A disk processing device holds and rotates a disk with a spindle. Processing tapes are supplied out and wound up by a tape reel unit so as to sandwich and be pressed on both surfaces of the disk through contact rollers. As a crankshaft is rotated, a sliding plate rotates around it and a slidable shaft rotates around a fulcrum part while sliding along the sliding plate such that the contact roller undergoes a reciprocating motion in a radial direction of the disk together with a slider rotatably attached to the slidable shaft.
