Abstract: It is an object to provide an X-ray generating apparatus of an integrate type, which permits easy alignment of an X-ray tube and easy insulation against high voltages and which has an X-ray shielding means superior in thermal conductivity. A screw through hole and pin through holes corresponding respectively to a screw hole and plural pin holes formed in an end face of a base portion of an X-ray tube are formed in an abutment face of a bracket against which the end face of the base portion of the X-ray tube comes into abutment, and a screw and plural pins are inserted respectively from the bracket side into the screw hole and plural pin holes in the X-ray tube through the screw through hole and the pin through holes, thereby mounting the X-ray tube to the bracket. The bracket is formed by an integral structure of FR4. An X-ray tube container which receives the X-ray tube therein is constituted by copper alloy plates with lead incorporated therein.

Abstract: An object of the present invention is to provide a circuit for generating a pair of well-balanced positive and negative dc high voltages, and an X-ray generator including such a high-voltage generation circuit. The X-ray generator includes a transformer, a pair of rectifier-type dc high-voltage generation circuits, and an X-ray tube. The transformer transfers an ac voltage, which is applied to a primary winding thereof and stepped up, from a single secondary winding thereof that has one terminal thereof grounded. The pair of rectifier-type dc high-voltage generation circuits generates positive and negative dc high voltages according to an ac voltage developed at the other terminal of the secondary winding. The positive dc high voltage is applied to the anode of the X-ray tube, while the negative dc high voltage is applied to the cathode thereof.
