  • Patent number: 11969712
    Abstract: A catalyst for purification of exhaust gas in which Pd-based nanoparticles and ceria nanoparticles are supported on a composite metal oxide support containing alumina, ceria, and zirconia, wherein a molar ratio (Ce/Pd) of Ce and Pd supported on the support is 1 to 8, a proximity ? between Pd and Ce is 0.15 to 0.50, wherein the proximity ? is determined, based on Pd and Ce distribution maps in an element mapping image of energy dispersive X-ray analysis, by the following formula (1): ? = ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( ( I ? ( i , j ) - I ave ) ? ( T ? ( i , j ) - T ave ) ) ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( I ? ( i , j ) - I ave ) 2 - ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( T ? ( i , j ) - T ave ) 2 , ( 1 ) a Pd dispersity after a heat-resistance test at 1050° C. for 25 hours is 0.8% or more.

  • Publication number: 20170078570
    Abstract: Deviations in a panoramic image obtained by compositing multiple images are corrected. An image processing device includes an image data receiving unit, a selection receiving unit, a three-dimensional position obtaining unit, a projection sphere setting unit, and a composited image generating unit. The image data receiving unit receives data of multiple still images, which are taken from different viewpoints and contain the same object. The selection receiving unit receives selection of a specific position of the object. The three-dimensional position obtaining unit obtains data of a three-dimensional position of the selected position. The projection sphere setting unit calculates a radius “R” based on the three-dimensional position of the selected position and sets a projection sphere having the radius “R”. The composited image generating unit projects the multiple still images on the projection sphere and thereby generates a composited image.
