    • A rotary cutting apparatus includes a pair of cutting tools each having a cutting blade along a tip end of its outer peripheral portion having a mountain-shaped cross section, and cuts a cylindrical material into pieces with a predetermined width by sandwiching the cylindrical material between the cutting blades so the cutting blades are respectively placed on inner and outer peripheries of the cylindrical material, and relatively rotating and moving the pair of cutting tools along an entire circumference of the cylindrical material. A second imaginary line connecting an axial center of the cylindrical material and an axial center of the inner peripheral-side cutting tool is shifted in a circumferential direction of the cylindrical material about the axial center of the cylindrical material with respect to a first imaginary line connecting the axial center of the cylindrical material and an axial center of the outer peripheral-side cutting tool.
    • 旋转切割装置包括一对切割工具,每个切割工具具有沿着其外周部分的顶端具有山形横截面的切割刀片,并且通过将圆柱形材料夹在两者之间将圆柱形材料切割成具有预定宽度的片材 切割刀片,使得切割刀片分别放置在圆柱形材料的内周和外周,并且沿着圆柱形材料的整个圆周相对旋转并移动一对切割工具。 连接圆柱形材料的轴向中心和内周侧切削工具的轴向中心的第二假想线相对于连接第一假想线的圆柱形材料的轴向中心在圆柱形材料的圆周方向上移动 圆柱形材料的轴向中心和外周侧切削工具的轴向中心。

    • A radiation detector comprises a scintillator 2A having a first end face 11, a second end face 13 disposed on a side opposite from the first end face 11, and a plurality of light-scattering surfaces 21 formed with an interval therebetween along a first direction P from the first end face 11 side to the second end face 13 side; a first photodetector 12 optically coupled to the first end face 11; and a second photodetector 14 optically coupled to the second end face 13. The light-scattering surfaces 21 are formed so as to intersect the first direction P. The light-scattering surfaces 21 include modified regions 21R formed by irradiating the inside of the scintillator 2A with laser light.
