Abstract
PURPOSE: To develop alarm signal correctly with less number of components, by converting the parallel input of alarm signal into series output in time sharing manner, even with more or less longer processing time.
CONSTITUTION: The alarm signals a1 to an are set to the shift register SHA with the output signal S1 from the N+1 notation counter CON, and the content of the shift registers SHA and SHB is shifted right every generation of clock signal CL by one bit after that, and the output S2 of SHA is inputted to SHB from the upper rank bit. Further, the output S2 is 1 and the NOT output S3 of SHB is 1, then the output S5 of the AND gate 2 is 1, to set FF2 and to develop the alarm signal ALS. The presence of the output S2 is detected with the detection circuit DET with the output S1 after that, and if no output S2 is present, FF2 is reset with the next output S1 to stop the alarm, and if the output S2 is present, FF2 is not reset and the alarm is continued until the STOP signal is inputted.
