  • Patent number: 11560365
    Abstract: A novel non-fluorescent rhodamine dye forms a twisted intramolecular charge transfer state. A substituent that causes steric hindrance is introduced at an ortho position of a dimethylamino group on the xanthene ring of tetramethylrhodamine, which is a general rhodamine that exhibits strong fluorescence, and a certain amount of twist is imparted in a ground state. As a result, the formation of the twisted intramolecular charge transfer state is promoted in the excited state and non-fluorescence is exhibited.

  • Patent number: 11561091
    Abstract: In measuring a dimension of an object to be measured W made of a single material, a plurality of transmission images of the object to be measured W are obtained by using an X-ray CT apparatus, and then respective projection images are generated. The projection images are registered with CAD data used in designing the object to be measured W. The dimension of the object to be measured W is calculated by using a relationship between the registered CAD data and projection images. In such a manner, high-precision dimension measurement is achieved by using several tens of projection images and design information without performing CT reconstruction.

  • Patent number: 11547340
    Abstract: An aspect of the present disclosure calculates a phase variance value indicating a degree of variance of a phase in a surrounding of each position in a biological tissue, based on phase values of excitation wave at respective positions in the biological tissue that acts in response to excitation caused by propagation of the excitation wave in the tissue, and generates an analysis map, based on a time series of at least part of the phase variance values at the respective positions. Since the phase variance value indicates the degree of variance of the phase in the surrounding, a position having a large degree of variance of the phase in the surrounding may be specified as a rotation center of rotating excitation wave.
