  • Publication number: 20180275607
    Abstract: An illumination apparatus includes a light source, a light guide plate, and an adjacent layer. The light guide plate includes a first surface, a second surface facing the first surface, and plural light exit portions provided on one of the first and second surfaces. The light guide plate guides therethrough a beam of light incident upon one of the first and second surfaces while reflecting the beam between the first and second surfaces. The light guide plate redirects the beam incident upon any one of the plural light exit portions so as to cause the beam to exit the light guide plate. The adjacent layer provided adjacent to at least one of the first and second surfaces has a lower refractive index than that of the light guide plate and increases a critical angle compared to that observed when air exists instead of the adjacent layer.

  • Patent number: 9939782
    Abstract: A hologram recording device includes a light outputting unit, which sequentially outputs laser beams having different wavelengths such that the laser beams are coaxial and includes an optical member and laser beam sources, and a recording unit, which sequentially irradiates the recording medium with the laser beams to record holograms in a multiwavelength superimposing manner. The optical member includes optical elements that reflect, in the optical direction, a laser beam incident thereon in a direction crossing the optical axis direction, and that allow a laser beam incident thereon in the optical axis direction to pass therethrough. The laser beam sources radiate laser beams to the optical member, and are arranged so that a laser beam emitted from a laser beam source among the laser beam sources that exposes a recording medium for a longer exposure period with the laser beam passes through a smaller number of optical elements.

  • Patent number: 9916242
    Abstract: A storage system includes control devices and a second processor. The second processor determines a number of abnormal batteries when an abnormality has occurred in a first battery. The second processor assigns a second cache currently assigned to a second control device associated with the first battery to a first control device when the number is smaller than a threshold. The second processor assigns a mirror cache currently assigned to the second control device to a third control device when the number is smaller than the threshold. The second processor instructs the first control device to control write to a first storage device associated with a first cache by using the first cache. Data of the first cache is mirrored to the mirror cache. The second processor instructs the first control device to control write to a second storage device associated with the second cache by using the second cache.
