摘要： In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.
摘要翻译： 在医用X射线CT装置中，旋转部旋转，通过旋转部旋转而在装置内产生风。 膨胀的盖部分被风强迫振动，产生噪音。 扩展盖部分设置有包括两端的至少一个弯曲构件。 弯曲构件被布置成沿着虚拟投影线延伸，所述虚拟投影线通过几何地投影虚拟直线而将虚拟直线彼此连接，固定到扩展盖部分的开口的外周边缘的两端连接到扩展盖的表面上 部分，并且膨胀盖部分的振动减小。

摘要： Fins are arranged on the rotating side of an X-ray computed tomography apparatus. The fins are rotated to generate airflow as the rotating side is rotated. This airflow serves to discharge wear debris to the outside of the X-ray CT apparatus, thereby preventing the wear debris from scattering toward an X-ray tube and support bearing. In consequence, in the X-ray CT apparatus provided with a slip ring, the wear debris produced in a contact space between the slip ring and a brush can be prevented from being scattered in the apparatus.

摘要： In a rotary anode type X-ray tube, a rotary anode and a rotary structure supporting the anode are arranged within the vacuum envelope. A stationary shaft has a middle section which is fitted into a cylindrical portion of the rotary structure, and a dynamic pressure type radial bearing is arranged between the cylindrical portion and the middle section. The stationary shaft also has a first section between one end of the middle section and one end of the stationary shaft, and a second section between the other end of the middle section and the other end of the stationary shaft, which are fixed to the vacuum envelope. A transverse stiffness of the second section is set to be larger than a transverse stiffness of the first section, and a center of gravity is positioned in the middle section.
