Abstract: PURPOSE: To enable the secondary side feedback control of a bridge inverter type X-ray device by supplying the anode voltage of an X-ray tube to a chopper as a specified control signal and inserting a resistor in a passage to which the accumulated energy of the primary side winding is emitted.  
     CONSTITUTION: The transistor drive circuits DR 1 ∼DR 4  of a feedback control means 3 are operated by an FF 2 . Chopper transistors TrQ 1 ∼Q 4  perform their specified operation and apply high voltage output voltage to an X-ray tube XT. Then at the fall time of a high frequency pulse when the TrQ 4  is set to ON and the  TrQ 4  is instantaneously set to OFF, the energy stored at the primary side coil T 1  of  a high voltage transformer HT is emitted through the TrQ 4 , a diode D 6 , and a resistor RA. Besides, when the TrQ 2  is set to OFF after a phase is switched, the accumulated energy of the coil T 1  is discharged through the TrQ 3 , a diode D 5 , and a resistor RB. Therefore, the resistors RA and RB are assigned to the same value. As a result,  the oscillation of the high voltage output is removed and the feedback control is  enabled from a voltage detection means 2.

Abstract: PURPOSE:To utilize stop zones effectively by installing a terminal equipment which transmits and receives a signal in the stop zones in addition to a terminal equipment which transmits and receives the signal on a couple of signal lines while providing the stop zones in packets. CONSTITUTION:The terminal equipment 2 which performs transmission and reception in the stop zones present between the packets of the terminal equipment which transmits and receives the signal on a time division multiplex basis on the couple of signal lines l is provided in addition to the terminal equipment 1. When the signal is neither transmitted nor received at the terminal equipment 1 for a specific time or longer, the terminal equipment 2 judges that the terminal equipment 1 enters a stop zone and then sends or receives the signal. The multipolar signal sent or received by the terminal equipment 2 is lower than the signal level of the terminal equipment 1 on both positive and negative sides, so the terminal equipment 1 does not decides that the signal is not a signal. Consequently, the signals of completely different systems are transmitted and received by using the same signal line l and the stop zones are utilized effectively.
