  • Publication number: 20240079918
    Abstract: [Problem] To provide a rotor unit that may effectively prevent detachment of a magnet with a holder while absorbing dimensional errors of a rotor main body and the magnet. [Solution] In the rotor unit according to the present invention, the holder mountable on the rotor main body prevents the magnet from being detached from the rotor main body. The holder includes an elastically deformable insertion arm extending from a flat-plate like holder main body, a hook portion provided on a free end side of the insertion arm, an elastically deformable magnet pressing arm extending from the holder main body, and a magnet pressing portion provided on a free end side of the magnet pressing arm. The rotor main body includes a hook hole into which the insertion arm is inserted, and the hook hole is provided with a locking portion in which the hook portion is lockable.

  • Publication number: 20080252862
    Abstract: A light reflector which can be manufactured easily by using a plastic base material that is light weight and low cost and has high reflectivity, and a method for manufacturing the same. The light reflector comprises a plastic base material 50 of which thermal deformation temperature is 130° C. or higher, and a reflecting film 52 containing silver and formed on the surface of the base material, wherein said plastic base material 50 is a molded article of thermosetting resin and the reflecting film has a smooth surface with PV (peak-to-valley) roughness of 0.5 ?m or less without sharp protrusions and reflectivity of the reflecting film is 96% or more.

  • Publication number: 20060137614
    Abstract: The metal film of the present invention is a dense film of a single crystal that has very low surface roughness and very good crystal orientation because an arithmetic mean roughness of the surface is not larger than 2 nm and a (111) peak intensity of X-ray diffraction is not less than 20 times the sum of all other peaks. Also the metal oxide film of the present invention is a dense film that includes less oxygen defects and almost no voids therein because a content of a non-oxidized metal is not higher than 1 mole % of a metal component that constitutes the metal oxide and a packing density is 0.98 or higher.
