    • A vitreous silica crucible has high strength at high temperature, and allows easy taking-out from a susceptor after completion of pulling. The vitreous silica crucible includes a vitreous silica outer layer provided on the outer surface side of the crucible, a vitreous silica inner layer provided on the inner surface side of the crucible, and an vitreous silica intermediate layer provided between the vitreous silica outer layer and the vitreous silica inner layer. The vitreous silica outer layer has a mineralizer concentration of 100 ppm or more, and the vitreous silica intermediate layer and the vitreous silica inner layer has a mineralizer concentration of 50 ppm or less. The thickness of the vitreous silica outer layer is 0.5 mm to 2.0 mm on the bottom portion, and the thickness on the sidewall portion of the vitreous silica outer layer is larger than that on the bottom portion.

    • The accuracy of combining positions of elongated images is improved at low cost, in a radiation imaging apparatus for generating elongated images having dimensions greater than a detectable range of a radiation image detecting means. A laser source is utilized.Displacement measuring means for measuring distances to targets by receiving a laser beam reflected by the subjects is provided. Positions that correspond to the ends of images in the movement direction of the radiation image detecting means are scanned in the direction perpendicular to the movement direction with the laser beam at each imaging operation. The displacement measuring means measures the positions of the ends of subjects in the laser scanning direction by receiving the laser beam reflected during scanning. An image processing means matches the combining positions of radiation images such that the ends of the subjects measured during each imaging operation are matched, and generates the elongated image.
    • 在用于产生具有大于放射线图像检测装置的可检测范围的尺寸的细长图像的放射线成像装置中,以低成本提高了组合放大图像的位置的精度。 使用激光源。 提供了通过接收被检体反射的激光束来测量与目标的距离的位移测量装置。 对应于放射线图像检测装置的移动方向上的图像的端部的位置在每次成像操作时用与激光束在垂直于移动方向的方向上扫描。 位移测量装置通过接收在扫描期间反射的激光束来测量被摄体在激光扫描方向上的端部的位置。 图像处理装置使辐射图像的组合位置匹配,使得在每个成像操作期间测量的被摄体的端部匹配,并且生成细长图像。
