  • Patent number: 7368052
    Abstract: A process is disclosed for discharging and transferring upwardly fluidized particles from a dense fluidizing layer forming section to a high-velocity transferring section having a diameter which is smaller than that of the dense fluidizing fluidized layer forming section, wherein at least one intermediate cylindrical section is provided between the dense fluidizing fluidized layer forming section and the high-velocity transferring section. The process can decrease the degree of changes in the amount of particles to be discharged from the dense fluidizing layer forming section and transferred by the riser, thereby proving a stable and uniform transfer of the fluidized particles.

  • Patent number: 6815037
    Abstract: This invention provides a carrier member made of a UV resistant fiber-reinforced composite material where a UV resistant coating material is applied on the surface of the fiber-reinforced composite material and a process for producing thereof. A preferable fiber-reinforced composite material is a fiber-reinforced plastic or carbon fiber-reinforced carbon composite material. A UV resistant coating material is one or more selected from the group consisting of ceramics, cermets, metals and alloys. The carrier member is produced by coating the surface of the fiber-reinforced composite material with a UV resistant coating material by spraying. This carrier member is advantageous in that it can exhibit properties inherent to a fiber-reinforced composite material such as a light weight, higher rigidity and higher heat resistance and that it little contaminates a precision instrument material when being used in cleansing with UV.

  • Patent number: 6744478
    Abstract: A head-up display system comprising a transparent plate. A liquid crystal display generates a display light of information with a plane of polarization inclined by about 45° relative to an image plane vertical axis. A first optical rotation layer is disposed on a first surface of the transparent plate, and receives the display light from the liquid crystal display and optically rotates the plane of polarization of the display light by about 90°. A second optical rotation layer is between the image plane of the liquid crystal display and a second surface of the transparent plate, and optically rotates the plane of polarization of the display light by about 45° and allows S-polarized light to emanate toward the transparent plate at Brewster's angle. The S-polarized light is reflected on the second surface and is directed toward an eye of an operator.
