  • Patent number: 8218213
    Abstract: A method of manufacturing a master for producing a hologram device. A first master is produced with a compensating angle. The second master is produced from the first master with an index matching material to reduce the interference pattern caused by internal reflections within the holographic plate of the master. The hologram device has a relatively narrow angle of reconstruction to provide visibility from a nearly perpendicular light source such as the headlight of an on-coming vehicle.

  • Patent number: 8215904
    Abstract: A groove 50 formed in each stator ring segment piece 41 is formed to have side wall portions 50b on opposite sides inclined with respect to a bottom 50a so that a width of the groove 50 gradually decreases from an outer peripheral side toward the bottom 50a. A coupling member 42 has a sectional shape so as to have a maximum width at protrusions 42b at an intermediate portion in a thickness direction. The protrusions 42b on the opposite sides abut against or approach the side wall portions 50b of the groove 50 when the coupling member 42 is placed in the groove 50, a space 100 is formed on the side of the bottom 50a of the groove 50, and a welding groove 200 having a substantially V-shaped section is formed on the side remote from the bottom 50a of the groove 50.
