  • Patent number: 11686868
    Abstract: An earthquake estimation method for more promptly estimating an earthquake on the basis of observation data. The earthquake estimation method includes, by a computer: generating an observation image showing a spatial distribution of seismic wave propagation on a basis of an observation result of seismic waves at a plurality of observation points on a ground; and estimating a parameter of an earthquake with respect to the observation image by using an earthquake estimation model in which a parameter of an earthquake including at least a position of a hypocenter and a magnitude is associated with a simulated observation image showing a spatial distribution of seismic wave propagation on a ground obtained from a result of a numerical simulation of the earthquake, performed with the parameter.

  • Patent number: 6617056
    Abstract: A transparent conductive laminate in which a crystalline transparent conductive film substantially made of In—Sn—O on a transparent substrate composed of a thermoplastic polymer film, is provided. The crystalline part of the transparent conductive film (ITO-film) has a specific crystalline structure in which the X-ray diffraction intensity from the (222) crystal plane or the (440) crystal plane is highest, and [X440/222], the ratio of the X-ray diffraction intensity from the (440) crystal plane to that from the (222) crystal plane, is within the range of 0.2 to 2.5. The laminate has a low resistivity, and it is useful as an electrode material for a liquid crystal display, an electroluminescence device, a touch panel or the like. The transparent conductive laminate can be manufactured by combining the control of film fabricating atmosphere during sputtering and a heat treatment under specific conditions after film fabricating.
