  • Patent number: 10520162
    Abstract: Provided is a high-decorativeness illumination device that utilizes lenticular lens sheets. An illumination device includes first to third lenticular lens sheets, an LED light source, and a casing. The first and second lenticular lens sheets are laminated such that an angle formed by plano-convex cylindrical lenses falls within a first angle range which is greater than 0 degrees and is less than 30 degrees. Accordingly, moire fringes appear in illumination light rays. The third lenticular lens sheet is laminated on the first and second lenticular lens sheets such that angles formed by plano-convex cylindrical lenses fall within a second angle range which is equal to or greater than 30 degrees and is equal to or less than 90 degrees.

  • Patent number: 10371955
    Abstract: Provided is a high decorative illumination device that utilizes a lenticular lens sheet. An illumination device includes a lenticular lens sheet and an LED light source. The lenticular lens sheet is curved in an X direction, and a convex surface is formed in a concave shape. The LED light source is positioned inside the convex surface of the lenticular lens sheet. First and second reflection components from first and second bright points which are acquired by reflecting irradiation light rays from the LED light source from plano-convex cylindrical lenses are incident on left and right eyes of an observer who observes the illumination device. The observer observes a virtual image as if a light emitter is present in a position in which the first and second reflection components cross each other.

  • Patent number: 8372318
    Abstract: A plurality of substantially conical or pyramidal elements are formed inside a sheet-like binder. The binder has smooth surfaces. The elements and the binder cooperate to refract light incident on a brightness enhancement sheet from a surface on a diffusion sheet side to the other surface in a direction normal to the brightness enhancement sheet. Thus, the front brightness is enhanced. The elements are distributed along one of the surfaces of the brightness enhancement sheet with vertices pointing in one direction toward one of the surfaces. The elements are formed by trapping gas bubbles in the binder and differ in refractive index from the binder.

  • Patent number: 7896541
    Abstract: A mixer for mixing liquid additive with polymer dope constituted by cellulose ester as polymer and solvent is provided. There is a mixing conduit for flow of the polymer dope. A supply conduit ejects liquid additive into the polymer dope in the mixing conduit. A rotor hub is positioned downstream from the supply conduit, contained in the mixing conduit rotatably about an axis directed in a flow direction of the polymer dope, and has a diameter decreasing end on an upstream side. A driving device with electromagnets rotates the rotor hub by electromagnetic induction through a chamber inside the mixing conduit. Furthermore, a support is disposed within the mixing conduit to extend transversely to the flow direction, for supporting the rotor hub rotatably. Flow openings are formed in the support, for passing the polymer dope in the flow direction about the rotor hub.

  • Patent number: 7891861
    Abstract: A mixer in a solution casting system mixes liquid additive with polymer dope fed through a flow line and constituted by cellulose ester as polymer and solvent. A mixer housing is in the flow line for passing the polymer dope through to be mixed. A supply conduit causes flow of the liquid additive for addition to the polymer dope. A distribution channel is formed with the supply conduit, positioned in the flow line, for spreading the liquid additive in a transverse direction of a flow passage in the flow line, to eject the liquid additive. A rotor hub is shaped with a decreasing diameter, contained in the mixer housing, opposed to the distribution channel, and directs the polymer dope in a ring shape after addition of the liquid additive. The flow line collects the polymer dope in a position downstream from the rotor hub.
