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 intensifying screen, comprising a support, a phosphor layer disposed on the support and a protecting film disposed on the phosphor layer. The phosphor layer comprises a first phosphor layer formed on the support side and constituted of particles of the first phosphor having average particle diameter D1 and range coefficient k, which expresses a particle size distribution, in the range of 1.3 to 1.8, and a second phosphor layer formed on the protective film side and constituted of particles of the second phosphor having average particle diameter D2 (>D1) and range coefficient k, which expresses a particle size distribution, in the range of 1.5 to 2.0. The ratio (CW1:CW2) of coating weight per unit area of the particles of the first phosphor in the first phosphor layer CW1 and coating weight per unit area of the particles of the second phosphor in the second phosphor layer CW2 is in the range of from 8:2 to 6:4. According to such intensifying screens, even when phosphors of, for instance, high emission efficiency are employed, while preventing lowering of speed and sharpness from occurring, granularity can be improved.

摘要： An exhaust gas-purifying system is provided for an internal combustion engine for use in a vehicle having an alternator driven by the engine to generate electric power. An electrically-heated catalyzer is arranged in the exhaust system of the engine and connected to the alternator to be electrically heated thereby. A changeover switch is provided for selectively switching the destination of electric power generated by the alternator to the electrically-heated catalyzer and to the electrical equipment. An ECU controls the electric power generated by the alternator, depending upon a direction in which the changeover switch has been switched. The ECU detects abnormality of the changeover switch, and when the abnormality is detected, the electric power generated by the alternator is changed to a value smaller than a value assumed when the changeover switch is normal.

摘要： A control system for controlling an alternator driven by an engine, for generating electric power, has a changeover switch for selectively switching destination of electric power generated by the alternator to a plurality of electric loads having respective different load voltage values. An ECU controls switching operation of the changeover switch and controls the alternator electric power, according to a direction in which the changeover switch has been switched. The ECU detects voltage of the alternator electric power when the destination of the alternator electric power is to be switched from a first electric load having a higher load voltage value of the plurality of electric loads to a second electric load having a lower load voltage value of the same, and causes the changeover switch to switch the destination of the alternator electric power from the first electric load to the second electric load after it is determined that the voltage of the alternator electric power has been changed from a predetermined higher voltage value to a predetermined lower voltage value.
