Abstract: A method for manufacturing a semiconductor apparatus for detecting radiation provided with phosphor comprises the steps of forming a phosphor layer integrally with a meshed partition plate having partitions per pixel of the semiconductor apparatus for detecting radiation, and of separating the phosphor per pixel by removing the phosphor on the partitioning portion of the partition plate by the irradiation of laser beam in the form of grooves together with the surface layer of the partitioning portions in order to make the phosphor thick to obtain a higher sensitivity, and also to make pixel pitches finer to enhance resolution, thus obtaining exact images without creating any cross talks between pixels.

Abstract: A large-area, compact and highly reliable radiation detector is produced by a process comprising the steps of laminating a phosphor sheet to a substrate having at least a photoelectric transducer, a driving element and a wiring matrix, and sealing the phosphor sheet and substrate thus laminated, by imparting a sealing medium to at least part of the peripheral portions of the phosphor sheet and the substrate, at least one of the steps being carried out in a vacuum chamber, to thereby bring the phosphor sheet into close contact with the substrate by atmospheric pressure.

Abstract: A sheet carrier apparatus of the present invention includes a first and a second rotary roller member, at least one of them having a rotary driving force. The second rotary roller member is constructed so as to be able to rotate around the first rotary roller member while it is being driven by the first rotary roller member. In order to control these rollers, the sheet carrier apparatus includes a control device for selectively setting the direction in which a sheet is moved from among a plurality of directions by controlling the rotary driving of the rotary roller members while carrying a sheet and by controlling the degree of angular displacement causing the second rotary roller member to rotate around the first rotary roller member while a sheet is grasped between them.

Abstract: The sheet conveying unit of the present invention has a roller for conveying a sheet which contacts therewith, a supporting portion for rotatably supporting both sides of the roller, a drive motor for rotatively driving the roller, and a frame portion for holding the supporting portion and the drive motor and making them integral with each other. The rotary shaft of the roller and the rotary shaft of the drive motor are a common shaft. The rotor of the drive motor is mounted on the common shaft, and the stator of the drive motor is mounted on the frame portion.

Abstract: In an image recording apparatus, a supply magazine and a receive magazine are arranged almost in a row, and a sheet transport path is formed along the periphery of both magazines. A recording sheet, which is taken out of the supply magazine, is once moved to a path whose transport resistance is small, so that the trailing edge of the recording sheet is completely out of the supply magazine. Then, a subscanning operation for image recording is performed along the path whose transport resistance is small.

Abstract: An apparatus for adjusting the inclination of an optical element or the like is provided with a predetermined shaft, an optical element fitted to the predetermined shaft, a mounting seat for supporting the optical element, a keep member for holding and fixing the optical element between it and the mounting seat, and a spherical seat movable in a direction intersecting the predetermined shaft between the mounting seat and the optical element for adjusting the inclination of the optical element. A method for mounting and adjustng the optical element includes the steps of mounting the optical element on the spherical seat supported on the predetermined shaft, detecting an inclination angle of the optical element and shifting the spherical seat to adjust the optical element.

Abstract: The present invention provides a laser irradiating apparatus which comprises a laser which can be directly modulated by a modulation signal, and in which laser oscillation becomes unstable when the intensity of the modulation signal is smaller than a predetermined threshold value, and laser oscillation becomes stable when the intensity of the modulation signal is larger than the predetermined threshold value, means for comparing the intensity of the modulation signal with a predetermined value near the predetermined threshold value, and means for modulating an emission time of the laser when the intensity of the modulation signal is smaller than the predetermined value.
