    Abstract: The present invention is a method for analyzing diffraction data obtained using a crystal structure analysis sample, the sample comprising a single crystal of a porous compound, and a compound for which a structure is to be determined. The method comprising: a step (I) that selects a space group that is identical to a space group of the single crystal of the porous compound, or a space group that has a symmetry lower than that, to be a space group of the crystal structure analysis sample; a step (II) that determines an initial structure of the crystal structure analysis sample using diffraction data with respect to a crystal structure of the single crystal of the porous compound as initial values; and a step (III) that refines the initial structure determined.

  • Publication number: 20080132335
    Abstract: A game controller including an acceleration sensor capable of detecting accelerations along three axial directions is moved to draw a figure pattern in a space. The positions pi of the moving path are derived from the acceleration sampled during the movement, and a path function and an approximate plane are calculated from the positions pi. An image obtained by observing the approximate plane in the normal direction is generated as a path image. The path image data is pattern-matched with reference pattern data to select a reference pattern with the highest degree of conformity, and the operation of a player character is controlled based on a magic actuation operation input instruction associated with the selected reference pattern.

  • Patent number: 7295699
    Abstract: An original image area IMR is divided into divided image areas DR1 to DR4, texture coordinates specified by division point coordinates are obtained, and images of the divided image areas DR1 to DR4 are mapped onto polygons PL1 to PL4, based on the obtained texture coordinates. The original image area IMR is divided in such a manner that division spacing in a direction DIR1 towards a vanishing point VP1 from the original image becomes narrower as the divided image areas are closer to the vanishing point VP1 and texture coordinates are obtained, to implement correction processing for removing perspective of the original image. Correction processing is performed to remove perspective of images at a base surface of images IL1 and IR1 for the left eye and the right eye, the images IL2 and IR2 for the left eye and the right eye are generated, and a stereoscopic image is generated by synthesizing (by anaglyph processing) IL2 and IR2.
