Abstract: A rotary anode type X-ray tube comprises a thin gas passageway extending from a lubricant chamber formed along the axis of a stationary structure and open at a fine gap G effective for preventing a lubricant leakage. In manufacturing the tube, a liquid metal lubricant is supplied to the lubricant chamber and to a slide bearing section, followed by assembling the tube and, then, sealing the assembled tube in a vacuum vessel. In the subsequent exhausting step, an open end of the gas passageway is allowed to face upward. The particular exhausting operation permits completely releasing to the outside the gas impregnated in the bearing-constituting members and the liquid metal lubricant, making it possible to maintain a stable bearing function.

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.

Abstract: 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.

Abstract: An X-ray tube has a cathode assembly for emitting an electron beam and an anode target facing this assembly in an evacuated envelope. The anode target defines a target surface that is slightly inclined to the electron beam axis and the direction in which it is inclined coincides with an X-ray irradiation direction. The cathode assembly comprises a flat cathode with a flat electron emission surface and a focussing electrode which focuses electrons emitted by the cathode. The cathode's electron emission surface is elongated and its long axis is coincident with the direction of X-ray irradiation. The focussing electrode possesses an axially symmetric opening with generally the same dimensions lengthways and crosswise. This gives an X-ray tube device in which the shape of the X-ray focal spot seen looking from the X-ray irradiation direction is substantially that of a circle or of a polygon, including a square, and it is possible to vary the size of the X-ray focal spot over a wide range while maintaining its long to short side ratio at 1.4 or less.

Abstract: An X-ray tube apparatus comprises an X-ray tube which includes a vacuum envelope and an anode target and a cathode assembly which are disposed within the vacuum envelope opposing each other. The cathode block has a flat-plate like filament for generating an electron beam, and a beam shaping electrode insulated from this filament. The beam shaping electrode is formed with a beam limiting aperture for passing therethrough of a part of the electron beam emitted from the filament, and a focussing dimple so as to focus the electron beam. When d2 and d3 are assumed to represent the depth of the focussing dimple and the distance between the target surface and the top surface of the focussing dimple opposing this target surface, respectively, the value of the ratio of d3 to d2 satisfies the inequality 1.0.ltoreq.d3/d2.ltoreq.4.0.

Abstract: An image forming apparatus includes a writing unit including an image data generation unit that produces image data; a main-sub image magnification processing unit that performs image magnification processing in a main-scanning direction and a sub-scanning direction; a clock generation unit that changes a writing clock period; a correction map that retains image magnification information corresponding to a deformation of a recording medium caused by application of heat and pressure from a fixing unit; and a light-emitting device that irradiates the photosensitive element with light. The writing unit slightly changes the writing clock period so as to enlarge or shrink a formed pixel in the main-scanning direction and perform enlargement or shrinkage in the sub-scanning direction, and thus cancel an image deformation caused by the deformation of the recording medium and correct a change in an image magnification in the main-scanning direction.
