摘要： A ceramic scintillator material consists of a sintered body of a rare earth oxysulfide phosphor containing Pr as an activator. The sintered body has a texture where coarse grains of irregular polyhedron and slender fine grains are intermixed. The coarse grains have a shape of for instance a dimension (average value) in the range of 50 to 100 &mgr;m, the fine grains having a shape of which average short axis is in the range of 2 to 5 &mgr;m and average long axis in the range of 5 to 100 &mgr;m. An area ratio of the coarse grains to the fine grains is in the range of 10:90 to 60:40. Such a ceramic scintillator material has, in addition to excellent light output (high sensitivity), mechanical strength capable of coping with downsizing of a detector. Furthermore, non-uniformity in sensitivity that causes artifacts can be decreased.

摘要： An object of the present invention is to provide a thermal spraying robot system capable of automatically determining spraying conditions according to the shape of a workpiece. Shape data on a workpiece (9) and material data on a thermal spray material are entered by operating a data input unit (1). A spray condition database 3 stores a plurality of spray parameters for kinds of thermal spray materials and for qualities of sprayed coatings. A path calculating unit (4) selects values of spray parameters from the spray condition database (3), and then calculates a path for a thermal spraying gun (14) according to a predetermined program on the basis of the shape data on the workpiece and the selected values of the spray parameters. The path calculating unit (4) decides whether or not a thermal spraying operation can be carried out by moving the thermal spraying gun along a calculated path. If it is decided that the thermal spraying operation is feasible, a thermal spraying apparatus 10 carries out the thermal spraying operation in which the thermal spraying gun is moved along the calculated path.
