  • Patent number: 8277687
    Abstract: The present invention relates to a phosphor that satisfies requirements (1) to (3): (1) the phosphor satisfies Formula [2] and/or Formula [3]: 85?{R455(125)/R455(25)}×100?110??[2] 92?{R405(100)/R405(25)}×100?110??[3] wherein R455(125) represents an emission peak intensity when the phosphor is excited by light having a peak wavelength of 455 nm at 125° C., (2) the emission peak wavelength is in the range of 570 nm to 680 nm, and (3) the full width at half maximum of an emission peak is 90 nm or less. The phosphor of the present invention has a high luminous efficiency and emits light of orange to red with high luminance. The use of the phosphor makes it possible to produce a light-emitting device, an illumination apparatus, and an image display, having a high efficiency and excellent color rendering properties.

  • Patent number: 6961683
    Abstract: Flexural rigidity E of a target wire harness (to be referred to as a WH hereinafter) is calculated by a predetermined bi-quadratic function associated with a curvature ? on the basis of a diameter ? of the WH, and the wiring shape of the WH which satisfy fixing positions is calculated on the basis of torsional rigidity C and the weight per unit length which are supplied from a storage device in accordance with the diameter ? of the target WH (S4-S5). The bi-quadratic function is set such that the calculated flexural rigidity E decreases as the curvature ? of the WH increases.
