Filed: 1989-12-29
Abstract: PURPOSE:To improve the reliability of the diagnostic device by applying a diagnostic program run signal to a runaway monitoring circuit in place of a normal program run signal and simultaneously reading the output of the runaway monitoring circuit to diagnose the presence or absence of the abnormality of the runaway monitoring circuit. CONSTITUTION:The diagnostic program run signal P-RUN is outputted through a port Pout1 of a microcomputer 1 in place of a normal program run signal and then applied to a runaway monitoring circuit 2. The output of a latch circuit 3 is read into a port Pin1 based on the output of the circuit 2. The given signal P-RUN is compared with the latch output serving as the result of the signal O-RUN for check of the correspondence secured between them. Thus, the presence or absence is checked for the abnormality of the circuit 2. When no abnormality is confirmed, a clear signal WDCL is outputted from a port Pout2 and the circuit 3 is reset. When the abnormality is confirmed, a system is locked. Thus, the presence or absence of the abnormality can be diagnosed for the microcomputer runaway monitoring circuit to improve its reliability.

IPC: G06T11/80
Filed: 1989-12-28
Abstract: PURPOSE:To eliminate an aligning operation and to shorten a time required for the input/editing work of a pattern graphic or the like by dynamically changing a display area in the aligning operation of a screen by means of an actual editing range on a screen. CONSTITUTION:A coordinate on the screen, which is obtained from a pointing device controller 17 is converted into a logical coordinate at first and it is stored in the position information preservation table of a memory 14 in a display area setting module 11. The position information preservation table always stores a prescribed number of the logical coordinates following the latest mouse cursor operation. In such a case, the display area which comes to a new object for setting is obtained from position information and compared with the present display area. Then, it is decided whether the new display area is to be set or not. Thus, the aligning operation is eliminated since the display area dynamically changes by the editing range in the aligning operation of the screen, and the time required for the input/editing work of the pattern graphic or the like can be shortened.
