    摘要： This invention relates to a monolithic IC having a PIN photodiode and an n-p-n bipolar transistor formed on a single semiconductor (silicon) substrate. In fabricating such IC, it is important to electrically isolate the photodiode and the bipolar transistor. In addition it is necessary to make the surface of the substrate flat. According to this invention, the inter-device isolation between the above-described two devices is attained by forming two epitaxial layers on the silicon substrate, forming trenches in the layers, and burying silicon dioxide in the trenches. In the monolithic IC according to this invention wiring capacity is small, and high-speed performance becomes possible. A p-type buried-layer is formed below the bipolar transistor to thereby prevent punch through between the bipolar transistor and other devices. Also this invention provides the process for fabricating a planar type bipolar transistor suitable to fabricate the monolithic IC and also provides a PIN photodiode of a new structure.

    摘要翻译： 本发明涉及具有PIN光电二极管和形成在单个半导体（硅））衬底上的n-p-n双极晶体管的单片IC。 在制造这种IC时，重要的是将光电二极管和双极晶体管电隔离。 此外，需要使基板的表面平坦。 根据本发明，通过在硅衬底上形成两个外延层，在层中形成沟槽，并在沟槽中埋入二氧化硅，可以实现上述两个器件之间的器件间隔离。 在根据本发明的单片IC中，布线容量小，并且可以实现高速性能。 在双极晶体管的下方形成p型掩埋层，从而防止双极晶体管和其它器件之间的穿通。 此外，本发明提供了一种用于制造适于制造单片IC的平面型双极晶体管的方法，并且还提供具有新结构的PIN光电二极管。

    摘要： An X-ray CT apparatus includes a scanner mounted with a detection system having an X-ray source for generating X-rays applied radially to an object and a detector arranged so as to be opposite to the X-ray source and adapted to detect the image of the transmitted X-rays transmitted through the object, wherein the scanner is rotated around the object. A three-dimensional X-ray absorption coefficient distribution image of the object is reconstructed from the transmitted X-ray image and the rotation-axis projection position which is the position where the rotation center of the scanner is projected on the detection plane of a two-dimensional sensor constituting the detector is decided. On the basis of the contrast of the X-ray absorption coefficient distribution image reconstructed by using the decided rotation-axis projection position, the rotation-axis projection position is estimated, and an X-ray tomographic image or/and a three dimensional X-ray image of the object is generated.

    摘要： When the laser-stimulable phosphor plate of an information reading apparatus for radiation image is constituted of CsI as the base and 0.0003 to 0.03% in atomic ratio of Na, the output signal of the information reading apparatus can be increased and the decay time thereof can be shortened. When output signals are produced by detecting fluorescence emitted from a fluoroscopic plate disposed in confrontation with the laser-stimulable phosphor plate, there is provided an information reading apparatus for radiation image having an improved S/N ratio and a high efficiency of taking in laser-stimulated luminescence. Further, instead of Na or together with Na, there may be added at least one element selected from the group consisting of Li, K, Rb, Cu, Au, Be, Mg, Ca, Sr, Ba, Zn, Cd, Hg, B, Al, Ga, In, Tl, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Si, Ti, Zr, Ge, Sn, Pb, As, Sb, and Bi. In this case, the total content of these elements is set to be 0.00001 to 1% in atomic ratio.
