Abstract: An oxygen concentration meter includes a zirconia sensor, a resistor, a constant-current circuit, a resistance detection section, and an oxygen concentration detection section. The resistor is connected in parallel to the zirconia sensor. The constant-current circuit is connected in parallel to the zirconia sensor and the resistor, and supplies an electric current. The resistance detection section detects the resistance of the zirconia sensor on the basis of the voltage of the zirconia sensor in accordance with the supplied electric current. The oxygen concentration detection section detects the oxygen concentration of gas to be measured that is supplied to the zirconia sensor, on the basis of the voltage of the zirconia sensor resulting from an oxygen concentration difference between the gas to be measured and reference gas.

Abstract: A laminate which comprises a core layer, a first cladding layer, a second cladding layer and a light reflecting layer, and wherein the light reflecting layer, the second cladding layer, the core layer and the first cladding layer are sequentially laminated. The refractive index of the first cladding layer and the refractive index of the second cladding layer are lower than the refractive index of the core layer, and the light reflecting layer has a thickness of 50 ?m or more.

Abstract: A laminate which is provided with a core layer, a first cladding layer, a second cladding layer and a light output means, and wherein the second cladding layer, the core layer and the first cladding layer are sequentially laminated. The refractive index of the first cladding layer and the refractive index of the second cladding layer is lower than the refractive index of the core layer. The light output means is composed of a recess that penetrates through the first cladding layer and reaches the inside of the core layer, and the curvature radius of the forefront part of the recess is 10 ?m or less.

Abstract: A picture-dimensionality check unit checks whether or not a picture to be reproduced is a three-dimensional picture containing a first parallax image and a second parallax image, which are images of an object from different points of view in a three-dimensional space. A display panel check unit configured acquires, from a display apparatus by which the picture is displayed on a display panel, information including the type of the display panel on the condition that the picture to be reproduced is a three-dimensional picture. A picture adjusting unit retrieves from a database a picture output condition that provides suitable display of the picture on the display panel, on the basis of the information acquired by the display panel check unit, and to adjust the picture in accordance with the retrieved picture output condition.
