Title: Watchdog timer
Inventor: KOSHI KAZUTOSHI
IPC: G06F11/30
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a watchdog timer which eliminates the need for manual recovering operation if a central processing unit(CPU) runs away, but is not out of order. SOLUTION: A decoder 21 decodes an address S1 outputted by the CPU 1 and generates a constant-cycle monitor signal S21b when the CPU 1 operates normally. If the CPU 1 runs away owing to noise, the monitor signal S21b stops and a detection signal S22 has transition from 'H' to 'L'. At this time, a differentiating circuit 23 differentiates the detection signal S22 to generate a control signal S23. The control signal S23 is supplied to the CPU 1 through AND circuits 25 and 26 and the CPU 1 is reset and restarts operating. A counter 24 counts how many times the detection signal S22 has transition from 'H' To 'L' and activates a carry signal S24 when its count value reaches a specific value. The carry signal S24 is supplied to the CPU 1 through AND circuits 25 and 26 and the CPU 1 stops operating.

An image pickup device 1 picks up the image of a test piece surface including a beam converging point having brightness of a specified luminance or higher and the picked up image is digitized and stored in an image memory. An image processor decides the position of the beam converging point based on information from this image memory and draws a cross line on the image memory according to the beam converging point. Thus, the position of a laser spot is easily and accurately understood by an operator.  Since there is a possibility that all of the formed images make translation on the surface of the image pickup device because of magnification changing or the like, the position of a converging point is calculated and a cross line is re-drawn for every magnification changing by a variable magnification part 11.
