Title: Waveform observing device
Inventor: ECHIZEN TETSUO
IPC: G01R13/20
Filed: 1984-10-29
Abstract: PURPOSE:To observe a normal waveform without any misunderstanding by detecting an overflow if it occurs and performing proper data processing for waveform data, and erasing an overflow waveform part from a display. CONSTITUTION:An input signal 10 is converted by an AD converting circuit 2 into waveform data, which is written in a memory circuit 3. Then, the waveform data which is stored temporarily is read out by a read circuit 4 to obtain waveform data Da8, which is processed by an overflow circuit 5 to obtain waveform data Db9. A liquid-crystal display element 6 displays a waveform on a liquid-crystal display screen on the basis of Db9. When an over input is applied to the circuit 2, the output of the circuit 2 consists of all bits 0 or 1 according to the polarity of the input and the circuit 2 generates an overflow signal 7. This signal 7 is 1 when an overflow occurs state or 0 when not. Thus, data processing is carried out for an overflow waveform part in Da8 to obtain Db9, and the display is erased to obtain an erased waveform part.

Title: Z-ray generating apparatus
Inventor: HACHIMAN MITSURU
IPC: H05G1/54
Filed: 1985-10-15
Abstract: PURPOSE:To enable protection of a X-ray tube even upon flowing of an abnormal current at the cathode side by producing a shortcircuit abnormal condition detection signal from a cathode side switching means upon exceeding of the center metal current over a normal level thereby closing an anode side switching means. CONSTITUTION:Upon occurrence of an abnormal condition at the anode or the cathode side, a detection circuit 3 will feed an abnormality detection signal immediately to a protection circuit 15. The protection circuit 15 will feed signals for informing an abnormal condition to an error display circuit 26 and a high voltage switch drive circuit 16. Immediately upon receipt of a shortcircuit fault signal at a cathode side high voltage switch 5, an anode side high voltage switch 4 is closed to apply a high voltage onto the anode 24 similarly with the cathode 25. Consequently, charges are discharged from the capacitors 13, 14 between the anode 24 and the cathode 25 of a X-ray tube 2 to cause current flow scarcely to a center metal 23. Consequently, the center metal 23 will never fuse.
