Abstract: PROBLEM TO BE SOLVED: To reduce the time required for bus arbitration and to set the bit rate of transmission frames to be high by converting a bit string of a priority code into a prescribed signal, sending the converted signal to a bus and sending a transmission frame next. SOLUTION: A specific priority code received by a terminal equipment 2 is converted into a serial signal by a bus arbitration section 4, and is further pulse-width-modulated, and given to a selector 6 as a bit string PB of the priority code. Then the bit string PB is sent to a serial bus 1 from a transceiver section 3 as a monopolar RZ pulse waveform current signal. The detection collision of the priority code in the case of transmission reception is conducted by comparing a transmission signal with a reception signal for each bit. When the transmission of the priority code is finished, a survival terminal equipment at the arbitration in the transmission operation uses an HDLC section 5 to send an HDLC frame.

Abstract: PURPOSE: To ensure safety in the operation of the combustion controlling apparatus comprising a heating conductor, a combustion fan, and ignitor, etc., by employing an arrangement in which the apparatus is kept inoperative condition if the output of a timer circuit for detecting extinguishment of flame is raised again to an ignition detecting level after the output of the timer circuit has become a low level due to going out of flame during combustion.  
     CONSTITUTION: A flame detecting and controlling circuit 5 in the combustion controlling opparatus is constituted by a flame detecting circuit 40, a timer circuit 41 for detecting extinguishment of flame and a relay driving circuit 42. The circuit 5 functions to raise the output of a comparator 55 to H-level, to energize a switching transistor Tr 58 and to energize a transistor Tr70 via a comparator 67 when normal state of combustion is detected by a frame rod 11 during the timer period determined by a capacitor 65. Resultantly, contact of the relay 12 is closed and combustion is continued in this state. On the other hand, if flame is extinguished during  combustion, said contact of the relay 12 is opened and operation of the combusting  apparatus is not recommenced since the output of the comparator 67 is kept at its  low level if the output of the frame rod 11 is raised again to a predetermined level.
