Abstract: An X-ray computed tomography apparatus including an X-ray source, a data acquisition unit, an X-ray detection unit, a reconstruction unit, a creation unit, and a display unit. An X-ray radiated toward an object by the X-ray source is detected to generate a corresponding signal by the X-ray detection unit. According to the signal, data is acquired by the data acquisition unit. A reconstruction unit reconstructs a tomographic image, while a creation unit creates a plane image based on the acquired data. A display unit displays the tomographic image and the plane image.

Abstract: An X-ray CT scanner comprises an X-ray source generating an X-ray, detector detecting the X-ray transmitted through an object, processor to produce projection data, and reconstruction unit to reconstruct an image using the projection data. The processor produces the projection image by applying, to an output signal from the detector, logarithm conversion processing on a function deviating from an ideal logarithm function. The ideal logarithm function is a logarithm function defined by a mathematical formula of y=K·log [b, x] (wherein a variable x is an input, a variable y is an output, and a reference K shows a scaling constant). The function deviating from the ideal logarithm function has an input/output characteristic deviating from that of the ideal logarithm function. Such deviating function is for example a linear function and applied to a conversion of only low-count data into its projection data to suppress low-count artifacts on reconstructed CT images.

Abstract: A two-dimensional array type of X-ray detector, incorporated into an X-ray computerized tomography apparatus, has a plurality of X-ray detecting elements arranged in the X and Y directions for detecting incident X-rays into electric signals. A mask is placed on the X-ray incidence side of the X-ray detecting elements. The mask is formed with a pattern of shield portions in line form each extending substantially parallel to the channel direction (X direction) to shield edges of all the X-ray detecting elements arranged in the x direction from incident X-rays. Thereby, the instability of sensitivity of X-ray detection of the edges of the X-ray detecting elements and arrangement errors of the X-ray detecting elements in the slice direction (Y direction) are canceled out.

A tile of the detection target light path is detected from the light receiving positions detected respectively.

Abstract: In an X-ray computed tomography apparatus, an X-ray tube for generating an X-ray is opposed to a main X-ray detector in order to acquire a projection data set necessary to reconstruct a tomogram. A first sub X-ray detector is arranged at the righthand of the main X-ray detector. A second sub X-ray detector is arranged at the lefthand of the main X-ray detector. Arranging the sub X-ray detectors adjacent to the respective opposite sides of the main X-ray detector enables accurate detection of the shift of an X-ray radiation field, and hence enables the reduction of errors due to the shift.

Abstract: There is provided a double walled pipe having an inner pipe and an outer pipe which is movable relative to the inner pipe in a longitudinal direction of the inner pipe. Acting on only the outer pipe with a pipe jacking power makes it possible to bury the double walled pipe, without damaging the rear end of the inner pipe and also generating an internal stress on the inner pipe. Consequently, it is avoided such a situation that even in use pinholes, cracks, etc. occur on the inner pipe, and thus it is possible to expect an execution with higher reliability.

Abstract: A fluid control solenoid valve includes a fluid passage having a valve seat therein. The solenoid valve further includes a bellows having a valve element and a retractable bellows portion continuous with the valve element. The valve element opens the fluid passage when lifted from the valve seat, and closes the fluid passage when seated onto the valve seat. A first spring urges the valve element in a valve lifting direction away from the valve seat, while a second spring urges the valve element in a valve seating direction toward the valve seat. An electromagnetic actuator is further provided for moving the valve element in the valve lifting direction, when energized. The first spring is interposed between an adjusting screw and the valve element. The adjusting screw is arranged to be extended at a high temperature so as to increase a biasing force of the first spring urging the valve element in the valve lifting direction.

Abstract: A thermoplastic resin having a Vicat softening point of 115.degree. C. or higher and containing a blowing agent is extruded and foamed into a foamed tubular body. The foamed tubular body is subjected to biaxial orientation and then pressed in antipodal directions, whereby the foamed tubular body is flattened and fusion-bonded at the resultant mutually-opposing inner walls thereof to obtain a foamed base material suitable for use in the fabrication of a car ceiling member. The foamed base material has not only excellent mechanical strength but also superb thermal strength. The foamed base material is not required to laminate films, sheets or the like thereon and is hence provided at a low cost.
