Abstract: PURPOSE:To detect and diagnose the generation of fault of plural circuit correspondence parts by inserting with branch the data on the branched j-th time slot to the (j+1)-th time slot in case said data is returned within a circuit correspondence part. CONSTITUTION:In a simultaneous diagnosis system to the same and different communication correspondence parts, the data on the j-th time slot TSj is returned at a circuit correspodence part LS1 and inserted to the (j+1)-th time slot TS(j+1) and sent to a diagnosis result deciding part M of a host computer via a branch circuit 152, a data reverse conversion circuit 153 and a data transmission line 12. The data on the slot TS(j+1) is branched to the next circuit correspondence part LS2 and returned to be inserted to the (j+2)-th time slot TS(j+2) and then sent to the part M in the same route as the data on the TSj. Hereafter the similar procedures are carried out, and each circuit correspondence part can be diagnosed individually. Thus it is possible to detect and diagnose the faults of plural circuit correspondence parts.

Abstract: PURPOSE:To perform power supply to an input-output device installed to a remote place from the main body of an electronic computer, by installing a no- break power supplying means, such as a battery, etc., to the connecting device of optical fibers. CONSTITUTION:The main body 1 of an electronic computer is connected to a connecting device 6 through another connecting device 4 and an optical fiber transmission line 5. Only a circuit of the connecting device 6 which receives signals from the transmission line 5 and detects whether an optical signal exists or not, is always set to an operable condition by means of a battery 7. If the connecting device 6 detects an optical signal coming from the transmission line 5 when input-output devices 8a-8n and the connecting device 6 are set to a condition where the AC power supply is cut off, the connecting device 6 performs its own AC power supply and succeedingly issues a turning-on command of AC power supply to the input/output devices 8a-8n. Therefore, power supply to an input/output device installed to a remote place from the main body of an electronic computer can be performed.

Abstract: PURPOSE:To attain ease of troubleshooting of a failed part by transmitting a data transmission line of a spare system to transmit a diagnostic data from a highway supervising node and demarcating a failed part with reflected data supplied from a station node at which an existing system transmission line is by- passed. CONSTITUTION:When a fault notice is received from a station node A, a highway supervising node B uses a data frame, transmits a by-pass command to the node A, which is brought to the by-pass state at a relay section 33 of the existing system. The node B transmits the diagnostic data to the spare system data transmission line side by the control of a microprocessor section 62 toward the node A. When the node A receives the said diagnostic data, a diagnostic control section 47 performs reflected control according to the reflected condition added to the diagnostic data and transmits a diagnostic response data to the node B. The node B compares the response data supplied from the node A with the transmitted diagnostic data to find out a failed part of the node A.

Abstract: PURPOSE:To diagonize a test pattern in every fixed period without exerting influence upon other communication and to attain preventive maintenance by sending the test pattern only in a previously specified time slot. CONSTITUTION:A monitoring node 21 and station nodes 22, 23 are connected through a ring-like transmission line 24 and data are transmitted/received by a frame including time slots. Control bit parts CTL 0, 1 are formed in the time slots TS#0-n and indicate normal data transfer when a bit CTL0 is ''0'' and a diagnosis mode in case of ''1''. An interval timer (not shown) generates an interruption to input a test pattern to an FIFO1, so that the CTL0 of the time slot on the corresponding part is turned on, the test pattern is sent, the returned data are stored in an FIFO2, and both the FIFOs are compared to diagnoze the corresponding part.

A clock CLRE for instructing a readout from a counter 32 is provided to this converter 31, and an output 34 of this converter 31 is turned back by the inside of the circuit corresponding part or the outside of a turning-back connector part, etc., and is provided to an S/P converter 35. The output is converted to parallel data by this converter 35 and it is written in a register 37. In this case, a write timing clock CLKS is provided to a selector 38 from a counter 36, and each data bit constitution of test data and the test adat which makes a round of a highway is made equal.

Abstract: PURPOSE:To simplify the control of a circuit corresponding part and to reduce the quantity of hardware, by providing a common controlled part with a memory and scanning the circuit corresponding part by an output pattern from the memory. CONSTITUTION:The contents of the memory 22 are read out by a time slot number arriving at a station which is an output of a frame counter 21. The data area of the memory which corresponds to the time slot number indicates that the circuit corresponding part assigned to the time slot and respective bits 0-7 constituting the data area corresponds to the circuit corresponding parts LS0- LS7. The bit ''1'' indicates the arrival of the time slot assigned to the circuit corresponding part corresponding to the bit. If the contents of the counter 21 indicates the arrival of the 30th time slot for instance, the 30th data area is read out from the memory 22. Since bit 1=1 is formed in the 30th data area, the corresponding part LS1 detects the arrival of the time slot assigned to itself and starts data transmission.

Abstract: PURPOSE:To easily manufacture a glass fiber for optical transmission with a small transmission loss by introducing chlorine gas or a gaseous chlorine compound into a multiple quartz crucible, heat treating the crucible, filling glass rods, and melt spinning the rods into a fiber. CONSTITUTION:Prior to introducing a core forming glass rod and a clad forming glass rod into a quartz crucible for spinning, the whole crucible is heated with heating furnaces 5A, 5B. When the heating temp. reaches about 1,400-1,450 deg.C, chlorine gas or thionyl chloride is introduced from core glass rod introduction hole 14 and clad glass rod introduction hole 15, and heat treatment is carried out for about 1hr. Thus, hydroxyl groups contained in the crucible are diffused, leach out of the inner surface, react with Cl2 or SOCl2, forming HCl, S02 and 02, which are removed. The glass rods are then introduced into the crucible thus heat treated, and a high quality glass fiber for optical transmission is obtd. by spinning.
