Title: Photo timer unit
Inventor: SUDA MASAO
IPC: H05G1/44
Filed: 1977-12-27
Abstract: PURPOSE: To enable to control the degree of black of X-ray films accurately, by using the reciprocal of the rate of degree of black for film to the change in the X-ray tube voltage as correction value.  
     CONSTITUTION: When X-ray exposure is started, the tube voltage given to the X- ray tube 1 is obtained from the X-ray controller 2, and the correction value to the tube voltage is read out from the memory 11 memorizing the reciprocal of the rate of the degree of black for film to the change in the tube voltage as the correction value. This correction value is D/A converted 12 and is fed to the operation circuit 13. On the other hand, the X-rays are passed through the film, then they are converted into optical image, and the output of the photomultiplier 9 receiving a part of them is fed to the circuit 13. Further, the circuit 13 multiplies two inputs and outputs the corrected detection output. This value and the set value for the optimum blackeuing degree are compared 14, and the exposure of X-ray is stopped when the output of the comparator 14 reaches the set value. Thus, the blackening degree control can be accurately made for the X-ray film.
