  • Patent number: 7380456
    Abstract: This three-dimensional ultrasonographic device is a three-dimensional ultrasonographic device having a matrix sensor 9 composed of a plurality of piezoelectric vibrators which are formed independently and arranged in a matrix, and it generates 3D imaging data based on reflected echoes of an ultrasonic wave obtained from the matrix sensor 9 and processes display images into two-dimensional images. Furthermore, this three-dimensional ultrasonographic imaging device connects a plurality of imaging data that are obtained while the matrix sensor 9 is moved, according to the position of the matrix sensor 9, thereby realizing imaging of a defect 14 for quantitative and intuitive judgment and enabling automatic judgment of the inspection. In addition, in imaging, an area other than an inspection area of the inspection object is masked, which realizes improved image quality.

  • Patent number: 5224971
    Abstract: In a typical method of separating isotopes, a linear material is fed between electrodes arranged in a vacuum vessel. Joule heat is generated by supplying a current to the linear material. A vapor flow is produced by heating and evaporating the linear material. Only a specific isotope in the vapor flow is selectively ionized by radiating a laser beam on the vapor flow. The ionized isotope is separated by using at least one of electric and magnetic fields. A typical isotope separating apparatus includes a vacuum vessel, a material feeder, a power source system, a laser optical system, and an ion separating unit. The material feeder feeds a linear material containing a plurality of types of isotopes between electrodes in the vacuum vessel. The power source system supplies a current to the linear material to heat and evaporate it.
