Title: X-ray device
Inventor: YAMAMOTO KAZUO
IPC: H05G1/56
Filed: 1986-11-28
Abstract: PURPOSE:To prevent generation of extraordinary high voltage by providing resistances in parallel to the primary coil of a high voltage generation device and connecting them selectively in accordance with a load condition. CONSTITUTION:A relay 17 is a relay which is liable to cause magnetic deviation, for instance, in the regions of high tube voltage and low tube voltage and operates in a short time, for instance, less than 50 ms of a photographing time. When a hand switch 19 for photographing is pushed, a sequence controller 16, a relay 18, a timer unit 15 and the thyristors 9, 8 and 10 operate by turns to perform X-ray radiation by an X-ray tube device 5. When the thyristor 10 operates to control and break the thyristors 9 and 8, a high power current flows due to magnetic deviation, energy accumulated in the inductance in the primary coil 201 of a high voltage transformer 2 is consumed by the resistances 20, 21 and 22 connected in parallel to the other coil 201 of the X-ray tube 5. The sufficiently low value is selected for these resistances in comparison with the equivalent value converted to the primary side of the high voltage transformer of the X-ray tube 5. Thereby, generation of extraordinary high voltage can be prevented.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which the color slurring of a toner image superposed on a body to be recorded is prevented by perfectly synchronizing the rotation of respective photoreceptor drums by a simple mechanism. SOLUTION: As to this full-color image forming device; the respective photoreceptor drums 4C, 4M, 4Y, and 4K, and a driving motor are connected by a connecting link 2 with the same phase, and also the outer circumferential length πϕ of the respective drums 4C, 4M, 4Y, and 4K is made equal to an interval (d) between them, and the driving signal of the driving motor is corrected based on the detection value of a rotational speed sensor 23 attached to the drum 4C farthest from the driving motor. Therefore, the rotation of the respective photoreceptor drums 4C, 4M, 4Y, and 4K is synchronized, so that phase and amplitude are matched even though rotational irregularity exists. Thus, the positions of the toner images transferred to a recording paper are aligned in respective colors, so that the color slurring does not appear.
