IPC: G01M99/00
Filed: 1978-09-29
Abstract: PURPOSE: To enhance the precision of abnormality detection by providing a function, which measures a time interval of a synchronizing signal given by the synchronizing signal generator and discriminates the count output, to the machine.  
     CONSTITUTION: When the synchronizing signal from the sensor 7 is normal, the counter 12 counts pulses proportional to the time interval between the rise time and the fall time. Since the count output is present within the range of permissible values, a normal signal is given by the comparator 13. When the synchronizing signal from the sensor 7 is abnormal, the count output is present outside of the range of permissible values. Thus an abnormal signal is provided by the comparator 13.
