  • Publication number: 20120326484
    Abstract: In a vehicle seat, a back side, that is a side opposite a seating side, of a cushion is covered by a backing that has less expandability than the cushion. The back side of the cushion is divided by a pair of first supporting members into a center portion arranged between the pair of first supporting members and a pair of side portions arranged on both sides of the center portion. The center portion and the side portions each have a semi-cylindrical outer shape that protrudes out from the back side of the cushion. First arranging portions that are recessed toward the seating side are formed between the center portion and each of the side portions. The first supporting members are arranged sinking into the cushion at the first arranging portions.

  • Patent number: 8283845
    Abstract: In a plane emission device comprising a transparent substrate, a light scattering layer formed on a surface of the transparent substrate, and a luminescent body of organic or inorganic material which is formed on a surface of the light scattering layer and emits light by light or electric energy, efficiency to takeout light to outside is improved. The light scattering layer contains binder and two kinds of fillers, and when a refraction index of the binder is assumed as Nb, a refraction index of one of the two kinds of fillers is assumed as Nf1, and a refraction index of the other is assumed as Nf2, a relationship that Nf2>Nb>Nf1 is satisfied. Since the light scattering layer contains two kinds of fillers, disorder occurs in critical angle when light exits from the light scattering layer to the transparent substrate, incidence rate of light into the transparent substrate rises, and efficiency to takeout the light to outside increases.

  • Patent number: 8237048
    Abstract: Disclosed is a multilayer organic solar cell having a structure wherein an inter-layer (3) is arranged between a first photoactive layer (1) and a second photoactive layer (2). This structure is obtained by forming the inter-layer (3) on the first photoactive layer (1) which is formed from an organic compound solution containing a donor material and an acceptor material, and then applying an organic compound solution containing a donor material and an acceptor material over the inter-layer (3) for forming the second photoactive layer (2). The inter-layer (3) is composed of at least either of a transparent oxide and a transparent nitride. By having such a structure, the inter-layer (3) prevents the solvent in the solution for the second photoactive layer (2) from permeating into the first photoactive layer (1) when the second photoactive layer (2) is formed over the first photoactive layer (1) by applying the solution.
