  • Publication number: 20150318542
    Abstract: A secondary battery includes a cathode, an anode including an active material, and non-aqueous electrolytic solution. The active material includes a center portion and a covering portion provided on part or all of the center portion. The center portion includes silicon, tin, or both as constituent elements. The covering portion includes a plurality of fibrous carbon materials. Part or all of the fibrous carbon materials extend in a direction along a surface of the center portion and are closely attached to the center portion.

  • Publication number: 20110164322
    Abstract: A UV-curable resin material composition coating liquid is provided and includes a UV-curable resin material composition dissolved or dispersed in a nonpolar solvent or a substantially nonpolar mixed solvent. The UV-curable resin material composition includes a monomer and/or an oligomer thereof that have two or more (meth)acryloyl groups, and affinity to a nonpolar solvent, modified hollow silica fine particles altered to have affinity to a nonpolar solvent by introduction of an aliphatic hydrocarbon group to surfaces of hollow silica fine particles, and a polymerization initiator.

  • Patent number: 7933069
    Abstract: A display device which is capable of generating more parallaxes without reducing resolution and an image quality, a display controlling method, and a program are provided. An aperture ratio of a light source is set as 1/N, and liquid lenses are disposed at distances of focal lengths of the first liquid lens and the second liquid lens from the light source, respectively. A position controlling portion changes a position of a nonpolar liquid by a size of each of luminescent pixels as represented by the first liquid lens and the second liquid lens, which results in that emitted lights from respective luminescent pixels pass through either the first liquid lens or the second liquid lens to be emitted in directions different from one another as shown in the form of lights. The present embodiments can be applied to a parallax image displaying device.

  • Patent number: 7636187
    Abstract: An optical shutter for a display device includes a partition wall surrounding and isolating a light-transmitting portion; a polar liquid having polarity, allowing light transmission, and placed at the light-transmitting portion; a nonpolar liquid having no polarity, blocking light, and placed at the light-transmitting portion; an insulator having hydrophobic properties and disposed over the entire light-transmitting portion; and first and second electrodes that are different. When no voltage is applied across the first and second electrodes, the nonpolar liquid spreads near the insulator, becomes stable, and thus blocks the light. When a voltage is applied across the first and second electrodes, the polar liquid gravitates toward the insulator because of a change in wettability of the insulator against the polar liquid and causes the nonpolar liquid to collect in part of the light-transmitting portion according to the level of the voltage, thereby controlling the amount of transmission of light.
