Abstract: An X-ray imaging device includes an X-ray detection section, a cold electron source, and a light-shielding coating layer. The X-ray detection section includes an X-ray conversion layer made of an X-ray converter material which generates electric charges upon incidence of an X-ray, a first charge injection blocking layer formed on an incidence surface of the X-ray conversion layer, and a second charge injection blocking layer formed on a rear surface of the X-ray conversion layer. The cold electron source has a plurality of electron emission sections arranged in a matrix form, each of the electronic emission sections being capable of emitting electrons toward the second charge injection blocking layer of the X-ray detection section. The light-shielding coating layer blocks incidence of the visible light into the X-ray detection section.

Abstract: X-ray camera of the present invention comprises an X-ray irradiation unit, an X-ray image sensor, a controller having a correction factor setting unit, a correction factor storage unit and a correctional operation unit, and a display unit. The X-ray image sensor in the above configuration comprises a sensor such as CCD, TFT, and the like having a scintillator on a surface thereof, and a substrate having the sensor mounted thereon. The correction factor setting unit obtains a value La/Ln by dividing a predetermined brightness reference value La set beforehand by a brightness value Ln of an arbitrary pixel “n”, and sets the obtained value as a correction factor for each pixel. The correction factor storage unit stores the correction factor set by the correction factor setting unit. The correctional operation unit obtains the correction factor from the correction factor storage unit, and performs a corrective operation.

Abstract: A plurality of X-ray detection means is moved in the location relative to an object of inspection whose place has been fixed at a certain specific location. Corresponding to positioning of the detection means, X-ray irradiation means is made to move, to make either a location shift or a revolution. A plurality of data on fragmental radioscopic images thus generated is integrated into a synthesized picture. An X-ray inspection apparatus in accordance with the present invention is compact in the overall dimensions, yet exhibits a superior performance needing a shorter time before a picture is displayed after it is detected.

Abstract: An automatic offset adjusting apparatus for current detectors in a digital controller for a servo motor is constructed so that, when errors occur in offset correction values due to a temperature change and the like while the servo motor is in operation, an electrical angle detecting unit detects a ripple of the torque of the servo motor, on the basis of a ripple of a torque command value, and detects a first electrical angle, where the torque command value becomes maximum, and a second electrical angle, where the torque command value becomes minimum, based on an electrical angle signal of the servo motor, a judgement unit judges whether or not offset correction errors have occurred on the basis of a difference between the first and second electrical angles, and, if the judgement unit judges that the offset correction errors have occurred, a correction unit adds adjustment values for the offset correction values corresponding to the first electrical angle to the respective offset correction values to update th

Abstract: An information storage apparatus (20) used in combination with an information processing device utilizes a plurality of magnetic disk units (22). The units are individually stocked in stocking locations of a stocking device (23). The stocking locations are assigned with different address numbers. On receiving an incoming signal from the information processing device, one of the units loaded into a disk driver (24) by a transporting device (49, 50) and a desired information data is recorded or reproduced on a flexible magnetic disk of the unit. The unit is thereafter returned to the initial location of the stocking device. Each of the units may have a recording medium. A recording and reproducing device (57) records or reproduces address information on the medium of the unit during transportation of the unit.
