The step signal of a rotating angle of the encoder 2 is output to the operation device 5. The operation device 5 judges whether the step value of the encoder 1 is close to a maximum step value or an initial value. If the step value is close to the maximum step value, a measured value is calculated from a revolution number before the encoder 1 makes the next one rotation and the step value of the encoder 1.  If the step value is close to the initial value, the measured value is calculated from the revolution number after the encoder 1 makes the next one rotation and the step value of the encoder 1, which is displayed 6.

Filed: 1989-07-28
Abstract: PURPOSE:To improve resolution characteristics via the employment of total reflection by depositing a low refraction layer having a refraction factor smaller than a phosphor to the aggregate of columnar crystals of the phosphor. CONSTITUTION:The input surface of an X-ray image tube is so made that the columnar crystal of a phosphor is formed on the predetermined curved surface, light absorption layer 35 and a cover layer 36 are deposited on one surface thereof and then separated, and a low refraction factor layer 38a and a photoelectric surface 40 are formed on the other surface. The low refraction factor layer 38a may be formed before the aforesaid separation process for the prevention of the occurrence of a pinhole 41 and the refraction factor thereof is made smaller than that of the phosphor. Consequently, among fluorescence generated due to the absorption of an X-ray at the pint B of a phosphor layer 33, light R1 totally reflected within the phosphor column advances straight to a photoelectric surface 40 and light R2 entering the phosphor is totally reflected with the low refraction factor layer 38a at a point C and absorbed. A drop in resolution due to the light R2 can, therefore, be eliminated.
