Title: Abnormality detecting method of computer
Inventor: ISOE YASUHITO
IPC: G06F11/00
Filed: 1984-02-15
Abstract: PURPOSE:To improve the detection of abnormal operation in a control system based upon a watchdog timer by detecting the abnormal operation from the generation of time-out of a timer to be reset by the execution of a reset subroutine. CONSTITUTION:A firmware program stored in a ROM2 writes a command (reset subroutine) for resetting the watchdog timer (WDT)5 in a RAM3. On the basis of the execution of the WDT reset command, a CPU1 generates a WDT reset pulse 400 through an I/O4 and supplies the pulse 400 to the WDT5. The probability of damage of the WDT reset command subroutine due to the runaway of the program is extremely high, and once the subroutine is damaged, the sending of the WDT reset pulse 400 is stopped. Thus, the abnormal state of the WDT5 can be precisely detected.

Abstract: PURPOSE:To eliminate the need to correct the phase difference automatically by providing a 3X3 coupler which divides a projection beam from a laser light source in two directions, an optical fiber for pressure reception, and an optical fiber for delay. CONSTITUTION:The projection beam from the semiconductor laser 1 is made incident on a constant-polarized-wave optical fiber 12 and this light is divided by the 3X3 coupler 10 into clockwise light (11 2) and counterclockwise light (2 11). The clockwise light (11 2) is delayed by a time DELTAt when it passes through the optical fiber loop 11 for delay and then varies in phase in an optical fiber loop 2 for sound field detection owing to variation in sound pressure, and the clockwise light and counterclockwise light are multiplexed by the coupler 10 to interfere with each other, so that an electric signal corresponding to the difference between acoustic waves is obtained when they are detected by photodetectors 7a and 7b. Consequently, an actuator and the automatic correction of the phase difference are omitted, so the system of the device is simplified and reduced in size and weight.
