  • Patent number: 9030775
    Abstract: In a disk drive device, a magnetic recording disk is mounted on a hub. A base rotatably supports the hub via a bearing unit. The base has a ring-shaped wall that surrounds the bearing unit and that protrudes towards the hub. A laminated core is fixed to the base. The laminated core has a ring portion and twelve teeth that radially outwardly extend from the ring portion. Coils are wound around the twelve teeth. The base includes an increasing-thickness portion formed so that the less the distance between a part of the increasing-thickness portion and the ring-shaped wall is, the thicker the part of the increasing-thickness portion becomes.

  • Patent number: 8758856
    Abstract: A method of fluoridation that can maintain a stable treatment quality is provided. The method of the fluoridation treatment performs the fluoridation treatment by heating and keeping a workpiece in a fluoridation treatment space filled with a predetermined fluoride atmosphere. By exposing an interior space structure that is reactive against fluorine within the fluoridation treatment space, forming a fluoride layer in advance on a surface of the interior space structure exposed within the fluoridation treatment space, and performing the fluoridation treatment, a fluoridation source gas supplied for the fluoridation treatment of the workpiece is not significantly consumed for fluoridating the surface of the interior space structure during the fluoridation treatment. Further, even when a fluoridation potential of the supplied fluoridation source gas is insufficient, the fluoride layer on the surface of the interior space structure discharges the fluoridation gas.
