Title: Runaway prevent circuit of microcomputer system
Inventor: KUMAMOTO HIROBUMI
IPC: G06F11/00
Filed: 1985-01-16
Abstract: PURPOSE:To prevent runaway due to faulty initial reset circuit by allowing a discrimination circuit to interrupt an output switch inserted to an output circuit so that the operation output of a CPU is fed to the system. CONSTITUTION:When a CPU reset pulse r2 is interrupted before an initial reset time (t) is elapsed because of a fault of a CPU initial reset circuit 2 and then given again, since no reset signal r1 is inputted to a reset terminal R' of a discriminating circuit 3, no output signal (b) is outputted to a terminal Q. Since an output switch 5 is interrupted, even when the reset state of a CPU1 is released and the operation is started, and output is not fed to the system. Thus, the reset time of the CPU1 is shorter than the initial reset time t', even when the initializing of the operating condition is insufficient, no erroneous operating result is outputted to the system.

Abstract: PURPOSE: To readily detect slip from a time deviation from the forecasting signal at an arbitrary pass point and the detection signal at a singular point by tracking the singular point on a steel plate by taking a reference signal from the roll which performs slip detection.  
     CONSTITUTION: A steel plate ST is wound on rolls R1, R2 and is being sent in the F direction. Steel plate singular point detectors WP1, WP2 are installed at fix positions P1 and P2 respectively and the detection of the singular points such as weld points, etc. of the steel plate is accomplished at each point. A pulse generator PG for tracking signal is provided to the roll of performing slip detection, e.g., R2 and generates pulse signals S5 for tracking. A counter C1 starts tracking of the steel plate with the signal S2 from the WP1 and starts counting of the signals S5. When the count value thereof becomes the preset value S1, i.e., the value corresponding to the slip length from P1 up to P2, a tracking completion signal S3 is generated. A signal non-coincidence detection circuit C2 makes comparison of the singular point detection signal S4 of the WP2 and the abovementioned signal S3 and when the signal generation timings deviate, it judges that there is a slip between the roll and the steel plate and generates a slip signal S6.
