摘要： PURPOSE:To make the troubleshooting of cause to failures easy, by storing an operation waveform at normal state, keeping this storage unchanged and detecting a failure through the change in the operation waveform. CONSTITUTION:In a failure detector 12, if a waveform comparator 24 detects a failure in a controller, a command signal to stop the collection of endless data is given to an endless data storage 27 after a prescribed time and the state of an analog signal 11 and a digital signal 10 of the controller before and after the generation of the failure is stored. This signal is trnasferred to an auxiliary storage device 27 such as a cassette tape for storage. When a display device shows the detection of the failure, the data stored in the device 27 is returned to the storage device 26, and the storage of the number of on/off times of a speed reduction relay can output the number of operations of the controller and at what number of times of the operation the production of the failure takes place to a printer 28. The information of the controller after and before the production of failure is outputted to a recorder 30 via an interface 29.

摘要： PURPOSE:To miniaturize a device and make it lightweight by inputting the output of the first double-voltage rectifying circuit constituted of the first rectify ing circuit and the first smoothing circuit to an inverter, and applying the output of the second double-voltage rectifying circuit constituted of the second rectify ing circuit and the second smoothing circuit to an X-ray tube. CONSTITUTION:For the used voltage of the single phase 200V, for example, it is half-wave double-voltage rectified by a half-wave double-voltage rectifying circuit constituted of diodes 2 and 3 and smoothing capacitors 4 and 5 and converted into the DC voltage of about 400V. This DC voltage is inputted to an inverter 6. A voltage control circuit 30 determines the operating frequency of the inverter 6 corresponding to the voltage transfer factor of the inverter 6 based on the relationship between the step-up ratio of a high-voltage trans former 16 and the preset tube voltage and controls the transistor of the inverter 6 via a base driving circuit 31. The inverter 6 applied with the DC voltage and the high-voltage transformer 16 generate the high-frequency voltage on the secondary side by resonance. The high-frequency voltage is converted into the DC voltage by two pairs of double-voltage rectifying circuits and applied to an X-ray tube 29 as the tube voltage.
