    Abstract: PURPOSE: To attain reconstitution of a transmission line at each section even at a fault putting a communication system into pieces by providing a communication frame generating function and a compensating delay time to all communication controllers of each terminal station and providing a function relaying a communication frame.
    CONSTITUTION: The function relaying the communication frame, that is, a func tion to be a master station is provided by providing a function generating a communication frame and a compensating delay time 13 to all the communica tion controllers 14 of each terminal station. When the communication frame is generated, an identification display to identify the communication controller 14 of a station from which the said frame is generated is added to the said frame. Each station detecting that the communication frame cannot be received due to a fault such as power failure becomes respectively a tentative master station to generate the communication frame and uses switches 10∼12, 20 to set a loopback line or bypass. Thus, even when a fault at which the communica tion system is divided into pieces takes place, the reconstitution of the transmis sion line at each section is attained.

    Abstract: PURPOSE: To connect many slow interface terminals by providing division number information in a time slot so as to use one time slot for plural slow interface terminals in command and assigning one time slot in time division made.
    CONSTITUTION: Information for discriminating a slow circuit time slot or a rapid circuit time slot has been previously stored in a time slot discrimination part (TSC) 20 in each time slot and discrimination information for a received time slot is outputted from the TSC 20 on the basis of a time slot No. obtained from a frame counter (FC) 14. A time slot conversion part (TSCG) 17 selects data outputted from a serial/parallel conversion part (SP) 15 and a division part (STSC) 21 in case of the slow circuit time slot or data from a device delay part (DLC) 16 in case of the rapid circuit time slot on the basis of the discrimination information input from the TSC 20 and outputs the selected data to a frame delay part (FBM) 18. After convertion into serial data, a parallel/serial conversion part (PS) 22 outputs the serial data to a data conversion part (EO) 19.

    Abstract: PURPOSE:To form the maximum highway from which a defective station node (SN) has been removed by using a self-transmission line switching function of an SN due to the fault of a transmission line to generate a false transmission line fault and switch the selecting system of SNs after the defective SN. CONSTITUTION:A false transmission line fault generating part 23 is formed on a station node SN and turns a switch SW2 or a switch SW3 on the basis of a false transmission line fault generating command from a supervisory unit SV. When the supervisory unit SV applies the false transmission line fault generating command to a station node SN1, transmission line faults are generated in respective nodes SNi after said node SN1 and the nodes SN2-SN5 detect the faults by respective supervisory parts LNCOs and turn the ''0'' system to the ''1'' system. Since the supervisory unit SV sends data to both systems, the nodes SN3-SN5 can receive data from the supervisory unit SV through the ''1'' system.

    Abstract: PURPOSE:To reduce the time required for a node address and also to simplify the control by allowing the own node address to be written in an idle time slot when a node address check command frame from a supervising node is received at each node. CONSTITUTION:When a program control section 8 receives a node address check command from a supervisory node through a data region circuit 7, the section 8 changes over a selector 10 to the position of a data line 11 from the control section 8. When an idle time slot is searched by a data line 12 and it is found out, the own node address is written in the time slot via the data line 11, a flag is set and the time slot is brought into the busy state. The supervisory node reads sequentially the time slot of the frame where the node address is written to check the arrangement of nodes and node addresses connected to a highway. Thus, the time required for the check by the supervisory node is reduced.

    Abstract: PURPOSE:To assign a line to a transmission side and a receiving side at nearly the same point of time by providing a channel address information storage part in a frame in a loop transmission system of the time division line exchange system having a supervising device. CONSTITUTION:The frame consists of a frame header FH and time slots TS0- TSl. The frame header FH is constituted by a synchronizing flag SYNC, a data part NT for communication between nodes, a trnsmission side address information storage part ADRS0 and a receiving side address information storage part ADRS1. The frame is formed and transmitted by a supervising station. When a transmission request is received from a station to other stations, the supervising station sets respectively a transmission side address and a receiving side address to the parts ADRS0 and ADRS1. When the receiving side is in a receptible state, it is informed to the transmission side by clearing the addresses.

    Abstract: PURPOSE:To attain a remote folding test, by folding back the test data transmitted from a test device at a line section of a line connecting device, in the state that the address number of the test line and the line folding are set. CONSTITUTION:Data transmitted from a line (a) of a communication controller 2 are transmitted from a line (b) of a line connection device 6 to a line (c) of a remote line connection device 7 being an address number. The data received on the line (c) are folded back at the setting of the line folding and transmitted to a line (d) of the device 6 being an address number as the transmission data of the line (c). The data received on the line (d) is transferred to a line (e) of the device 2, and the transmission data of the line (a) and the reception data of the line (e) are compared. Through this comparison, the test of the data highway system is executed.

    Abstract: PURPOSE:To efficiently perform the thermal oxidation reaction of gaseous starting material and the deposition of soot with simple constitution by putting a rodlike body in a reaction tube from the gas exhaust side end, locating one end of the body in the vicinity of a heating means, and moving the body in synchronism with the means. CONSTITUTION:A reaction tube 1 is attached to a rotating and supporting mechanism 2, and a burner 3 is moved in the longitudinal direction of the tube 1 to locally heat the wall of the tube 1. In order to reduce the hollow cross section of the tube 1, a rodlike body 22 having a suitable thickness is coaxially put in the tube 1 from the gas exhaust side end 21, and one end of the body 22 is located in the vicinity of the burner 3. The body 22 is moved in cooperation with the burner 3. The other end of the body 22 is held by a holder 24 on a moving stand 23 on which the burner 3 is mounted. The body 22 is not a nonhollow rod, and it is internally provided with a heater 25 not to stick soot to the outside peripheral surface 22 since the central part of the tube 1 is likable to be heated to a lower temp. than the tube wall.
