Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To enable estimating of both levels of mark and space of a bucket signal in every bucket with high accuracy by setting variably a discrimination level supplied to a discriminator and varying calculation parameter according to the discriminating level value. SOLUTION: A discriminator 3 having a plurality of light bucket signals sent out of different sources as inputs from a light receiver discriminates the number of bits of a digital signal. The bit error rate of this output signal is measured by an error rate measuring instrument 7 and the level of digital signal is calculated in a calculation section 8. Then, a discrimination level generator 4 sets variably the discrimination level supplied to the discriminator 3 to vary calculation parameters of the calculation section 8 according to the level value. Namely, the calculation section 8 reads out the corresponding calculation parameters interlocked with the set signals of the discrimination level from a memory 9 to calculate the average and dispersion of normal distribution of light signal levels according to the measured bit error rate.  And according to the calculation result, the mark level and space level of light bucket signal are calculated in every bucket.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To instantaneously detect a task stack overflow and to improve the reliability of a stack by interrupting a CPU when an address value on an address line exceeds a set stack upper limit value. SOLUTION: At the time of starting a task A, a stack upper limit value is read out from a task control block 5 and the read value is set up in a task stack upper limit value setting register 1.

Abstract: PURPOSE:To unitarily control communication error information by sending communication error information from a transmission side to a bus type packet communication network by a broadcast communication system when the communication error information is stored by a predetermined number of times, and receiving and storing the communication error information on a reception side. CONSTITUTION:Communication control equipments 2-4 send/receive packet signals to one another through the bus type data transmission line 1 and store information on a communication error when the error is detected.

Abstract: PURPOSE:To clarify the location of a core pin to be replaced by making it possible to immediately indicate the broken portion of the core pin by a constitu tion wherein the breakage of the core pin is made detectable by means of through holes and transmitted light through slits. CONSTITUTION:Through holes 15, which are bored crosswise and normal to the longitudinal direction of a core pin 13 and through which light can transmit, are made on each core pin 13. When a sound core pin 13 and a butt pin 14 abutt against each other, the through holes 15 are in such a state as to coincide with a slit made between a stationary side back up plate 3 and a retainer plates 4 so as to communicate with each other. If a core pin 13 is broken by some cause or other, the core pin 13, which is pressed toward the retainer plate 4 side at all times by a spring 19 is immediately shifted toward the butt pin 14 side. Accordingly, the through hole 15 of the core pin 13 does not coincide with the slit 16 and the light emitted from the light emitting part 21 of a photoe lectric switch corresponding to said core pin 13 is not received by the light receiving part 22 of the switch.
