    摘要： An X-ray imaging apparatus including an X-ray generation means for emitting X-rays, and an X-ray detector on which a grid selected from a plurality of different types of grids is removably mountable. The X-ray detector receives the X-rays emitted from the X-ray generation means, and obtains an X-ray image. The X-ray detector includes an automatic exposure control (AEC) detector for detecting the quantity of X-rays emitted from the X-ray generation means and for outputting a signal based on the detected quantity. The X-ray imaging apparatus also includes a control means for controlling the X-ray generation means and the AEC detector, where the control means controls the X-ray generation means based on the signal output from the AEC detector, and where the control means controls the AEC detector using correction data to correct an exposure detection element forming a part of the AEC detector.

    摘要： Image sensing radiation detection pixels of m (columns)×n (rows) are divided into, e.g., 72 pixel regions. Image sensing radiation detection pixels belonging to one pixel region are connected to the same read TCP and driving TCP. For example, three regions (AEC radiation detection regions) of the 72 pixel regions have a plurality of AEC radiation detection pixels. An AEC radiation detection pixel has a TFT sensor. Spare wiring lines for the AEC radiation detection pixels are arranged at two side portions of each read TCP. Each spare wiring line is connected to a predetermined circuit in a read device to connect the AEC radiation detection pixels to the predetermined circuit so that the AEC circuit is operated.

    摘要： The object of this invention is to provide an imaging apparatus capable of providing a high-quality image optimum for medical diagnosis or the like by an arrangement for preventing any degradation in image quality due to the influence of electromagnetic noise and vibration caused by grid movement. In order to achieve this object, as operation control in receiving radiation transmitted through an object by an image sensing element through a movable grid and reading the accumulated signal from the image sensing element, a control device stops moving drive movement of the grid after the end of radiation irradiation for the object, and after the stop of moving drive stopping the movement, starts reading the accumulated signal from the image sensing element.

    摘要： In a chain transmission, the link plates of a roller chain or rollerless bushing chain are formed with pairs of teeth. A sprocket has a central set of sprocket teeth for meshing with the rollers or bushings, and sets of side sprocket teeth for meshing with the teeth of the link plates. The teeth of the link plates function as a silent chain. After an inner flank of a link plate tooth comes into contact with a side sprocket tooth, a roller and an outer flank of the link plate tooth are seated on the sprocket.
