摘要： An X-ray image intensifier has an input phosphor screen with a substrate in which a large number of small holes are formed, and a fluorescent material filled in the small holes. A ratio of a maximum inner diameter to a depth of each small hole is set to be 0.5 or less. Alternatively, the input phosphor screen of the X-ray image intensifier of the invention includes a substrate in which a large number of small holes are formed, a low-refractive-index material layer formed on the inner wall of each small hole, and a fluorescent material having a refractive index higher than the low-refractive-index material layer filling each small hole. The input phosphor screen of the X-ray image intensifier of the invention is manufactured by forming a large number of small holes in a substrate composed of photosensitive glass, forming the substrate into an arcuated shape by hot pressing, converting the substrate into crystallized glass by a heat treatment, and obtaining an input phosphor screen by filling the small holes with a fluorescent material.

摘要： An X-ray image intensifier includes an input screen for converting incident X-rays into photoelectrons, and an output screen for converting the photoelectrons into visible light. The input screen includes a phosphor layer. The phosphor layer has a large number of columnar crystals of a phosphor which have end faces constituting a smooth surface facing the output screen. A low-refractive-index layer is formed on the phosphor layer and made of a material having a refractive index smaller than a refractive index of the phosphor, with respect to the light having a specified wavelength, at which the fluorescence of the phosphor is the most intensive. A photoemissive layer is formed directly or indirectly on the low-refractive-index layer.

摘要： A supporting member supports an anode target at one end thereof and is provided with an attachment portion around the outer circumference of the other end. The attachment portion is attached to the inner circumferential surface of the cylindrical portion of the second vacuum envelope member so that the heat conductivity from the supporting member to the second vacuum envelope member can be improved by means of the attachment portion. A terminal is provided at the end surface portion on the side of the other end of the second vacuum envelope member for applying a voltage to the anode target. The terminal is positioned away from the attachment portion so that the temperature of the insulating material that insulates the terminal can be kept low and the insulating characteristics can be ensured over the long term.

摘要： An anode target is roratably supported by a rotating mechanism having a rotary body and a staionary body. A fitted portion between the rotary body and the stationary body is formed of bearing areas having dynamic pressure type sliding bearings and a non-bearing area having a clearance between the rotary body and the stationary body larger than that in the bearing areas. The rotary body facing the non-bearing area is positioned where a time for heat transfer from the anode target is shorter than the rotary body facing the bearing areas. Thus, the characteristics of heat radiation from the anode target can be improved, and a stable bearing operation can be maintained.

摘要： An x-ray tube apparatus comprises a cathode structure emitting an electron beam, a anode target arranged to face the cathode structure, a rotary structure fixed to the anode target, a stationary shaft having bearings arranged between the stationary shaft and the rotary structure for rotatably supporting the rotary structure, and a vacuum envelope provided with an x-ray transmitting window for taking the X-ray generated from the anode target to the outside. The end portion of the stationary shaft on the side of the cathode structure and the other end portion on the side of the anode terminal are fixed to parts of the vacuum envelope. Particularly, the joining portion on the side of the cathode structure is deviant from the axis of rotation of the anode target and the rotary structure and positioned on the side opposite to the cathode structure and the X-ray transmitting window with respect to the axis of rotation. In the x-ray tube apparatus of the particular construction, the dielectric strength on the side of the cathode structure can be sufficiently maintained, and the apparatus can be made compact.
