Abstract: In an envelope rotation type X-ray tube apparatus 1, a cathode 5 releases electrons, and the electrons released from the cathode 5 are deflected by deflection coils 6. A target 7 generates X-rays by being bombarded with the electrons deflected by the deflection coils 6. Here, a shield ring 11, while allowing passage through a ring interior of those of the electrons deflected by the deflection coils 6 that head for an area F of the target 7 set beforehand, blocks electrons heading outward of the area F. Consequently, the electrons are inhibited from bombarding on areas of the target 7 outward of the area F and an envelope 2. This can prevent damage to the envelope 2.

Abstract: 【課題】変形を防止しつつ、安定した焦点を維持することができるフィラメントの調整方法およびX線管装置を提供することを目的とする。【解決手段】部分的に中央の領域を点灯させる場合において、通電する電流値をそれぞれ調整することで、部分的に中央の領域を点灯させる領域を除く周辺部分では電子が放出しない温度範囲に加熱電流値を調整する。この調整により、点灯させる中央の領域が加熱されるとともに、その周辺部分も電子が放出しない温度範囲で加熱される。その結果、点灯させる中央の領域と周辺部分との間での温度差が小さくなり、熱応力による変形を防止することができる。よって、フィラメントの寿命期間を通じて、フィラメントが変形しない平坦度を維持した状態が得られる。これにより、安定した焦点を維持することができる。【選択図】図3

Abstract: PROBLEM TO BE SOLVED: To provide an X-ray tube device in which soft X-rays are cut off or the soft X-rays are not generated. SOLUTION: The inner circumference portion of an anode 6 has a structure to cut-off soft X-rays by a level difference 6 by installing the level difference 6a which is a projection at the inner circumference of the anode 6. When a load is applied on the X-ray tube device 1 for generating X-rays, the controller 11 controls a deflecting coil 5 so as to collide electron beams B on the outer circumference of the anode 6, and at the completion of the load, the controller 11 controls the deflecting coil 5 so as to collide the electron beams B on the inner circumference of the anode 6. Since, as above, the controller 11 controls the deflecting coil 5 so as to collide the electron beams B on the inner circumference of the anode 6 at the completion of the load, and the inner circumference portion of the anode 6 is constructed in a structure of cutting off the soft X-rays, the soft X-rays are cut off at the completion of load (at the timing of wave tail).

Abstract: PROBLEM TO BE SOLVED: To provide an X-ray tube device in which the size of focus electrode need not be large and the focal size can be changed while the focal profile is made not to be changed for any focal size.
SOLUTION: The three electrodes 13-15 insulation-fixed at the bottom of a groove 12 of an insulating block 11 have an analogous outline and are arranged in concentric form and are formed with a group of carbon nanotubes on the front surface and a gate 16 is arranged in front of these. A focus electrode 17 having a groove (hollow part) corresponding to the groove 12 is installed on the insulating block 11. Negative potential is selectively given to the electrodes 13-15 by switches 21-23 and electrons are emitted from the electrodes turned into negative to the gate 16, and passing through the gate 16 and focused by the focus electrode 17, proceed to the anode. Since the outline of the electrodes 13-15 is made analogous, only the size of electron emission face is different, and emission face is maintained in the analogous shape, and the X-ray focus is similarly maintained in analogous shape and only the size is different.

Abstract: PROBLEM TO BE SOLVED: To provide a surgical X-ray TV apparatus which is operable for a long period of time by suppressing the temperature elevation of an X-ray tube device by improving efficiency in heat conduction.
SOLUTION: Both ends of a heat radiating pipe 39 which is added to a C arm 9, are communicated and connected into a housing 19, and an insulating oil within the housing 19 is circulated in the heat radiating pipe 39 by a circulating pump 41.

Abstract: PURPOSE:To improve short time inpur rating while unifying electron distribution on the focus target by operating an electron lens system provided on a cathode in a non-linear symmetrical form to the central axis in the longitudinal direction of a long and narrow X-ray focal point. CONSTITUTION:A rotary anode type X-ray device for stereo radiography is formed of a rotary anode 2 provided with a target 3 and the cathode part 4a having two focusing electrodes 5a and 5b at intervals of a fixed distance. Thereby, the focusing electrodes are made to be the focusing electrodes 5c and 5d, in which the primary electron lenses 6c, 6d and the secondary electron lenses 7c, 7d arranged outside its filaments 8c and 8d are made into a non-linear symmetrical form to the central axis in the longitudinal direction so as to form the approximately diamond-shaped effective focal points 9c and 9d. Accordingly, the electron distribution density can be made same and unified in the central part as well in-and-outside of the focal points while being able to improve short time input rating for heightening diagnosis capacity.

Abstract: PROBLEM TO BE SOLVED: To provide a flat plate filament to be used for an envelope rotary type X-ray rube device to prevent the deformation of a focal point due to the thermal expansion of the flat plate filament.
SOLUTION: On the circular flat plate filament 3 including a pair of electrode plates 22, a concentric slit 28 and a linear slit 29 are formed. Thus, current paths 30 are formed which repeat branch from one electrode plate 22 and joint to the other. In the current paths 30, a filament current supplied from the electrode plate 22 flows. The current paths 30 have uniform thermal expansion, because they are formed line-symmetric to a straight line between each of the pair of electrode plates 22 and the center of the flat plate filament 3 while repeating branch and joint on the straight line between the pair of electrode plates 22.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that in the case of X-ray photographing to carry out the radiography prior to the photographing, since the photographing is carried out at more preferable timing as the delay time in shifting from the radiography to the photographing becomes shorter, in order to solve a delay of change of an anode electrode rotating speed which is one of the causes of the delay, a method to rotate an anode electrode at the same speed at the radiography as that at the photographing and to use it is considered, but an X-ray tube becomes unable to be used within an extremely short time in comparison with a regular method because of relation of a rotating life by this method.
SOLUTION: An X-ray control device 20 automatically decides a photographing condition from an appropriate radiography condition and also determines the allowable minimum value of the anode rotating speed of the X-ray tube in the photographing, and changes the anode rotating speed during the radiography according to this value.
