Title: Fault deciding method for microprocessor
Inventor: HIROTA KAZUHIKO
IPC: G06F11/30
Filed: 1990-07-06
Abstract: PURPOSE:To decide the faults with each other between two microprocessors by detecting the error signal received by each opposite side and monitoring the state of the opposite side based on the error signal among plural microprocessors. CONSTITUTION:When the 1st and 2nd microprocessors 10 and 11 have no fault, the pulses of L levels, for example, are not outputted from the timer output terminals of the RAM 12 and 13. When the internal counters of both processors 10 and 11 reaches the prescribed values, the LED 20 and 23 are turned off. If the processor has a fault, a pulse of an L level is outputted from the timer output terminal of the RAM 12 and an error detecting circuit 15 produces an error signal. Thus the processor 11 undergos the inhibition of its interruption and the LED 23 is turned on. Thereafter the LED 23 is turned on and at the same time the processor 10 is reset as long as this processor is not reset to a normal state yet.

Title: Driving method of laser for exciting optical fiber amplifier
Inventor: IZUMIKAWA TOSHIHARU
IPC: H01S3/067
Filed: 1992-06-12
Abstract: PURPOSE:To output a laser for excitation having power higher than the rating of a laser diode from the laser diode. CONSTITUTION:Two or more of laser diodes 1 are controlled by a pulse driver circuit 2, laser beams A, B for excitation are emitted alternately from each laser diode 1, and the laser beams A, B for excitation are synthesized and fed to an optical fiber amplifier 3. Consequently, the power consumption of the driver circuit for the laser diodes can be lowered. Since switching distortion due to pulse driving is offset, light to be amplified is not subject to the effect of the offset. Since noises due to switching are absorbed to a laser for excitation by the characteristics of an erbium-doped fiber, amplified light is not subject to the effect of the noises.
