    摘要: One dimensional X-ray image sensor (3) is comprised of a plurality of unit detecting devices (3u) aligned in a row and a filter (4) which covers a portion thereof and is made of a material having an X-ray absorption coefficient equal to or nearly equal to that of a target material (7,8) to be inspected.
    Also, an X-ray inspection apparatus including the one dimensional X-ray image sensor is disclosed. It includes further a data processor (28) for correcting measured values using data measured in regard to the filter.

    摘要: An energy difference picture processing method comprises the steps of using a semiconductor radiation detector; providing two discriminating levels; dividing X-rays, which have passed through objects ((1)1 and (2)2), into two kind energy zones; counting X-ray photons to obtain an X-ray picture; assembling, with corresponding coefficients, S(H), S(L), {S(H)} x and {S(L)} y , which are exponential functions of the S(H) and S(L), respectively, where S(H) is a logarithmically converted version of a picture of counts in a higher energy band and S(L) is a logarithmically converted version of a picture of counts in a lower energy band; and performing addition, subtraction, multiplication and/or division on these terms to provide a picture in which a particular one of the materials constituting the objects is selectively extracted or removed.

    摘要: A method for controlling a moving velocity of an ultrasonic motor comprising a vibration body for causing ultrasonic vibration in response to two AC driving voltage signals having a common frequency, a common amplitude and phases different from each other; and a moving body in contact with the vibration body and moved by the ultrasonic vibration. The method includes step A of detecting a velocity of the moving body; step B comparing the velocity detected in step A with a predetermined velocity; and step C for adjusting the frequency of the two AC driving voltage signals and the amplitude of or the phase difference between the two AC driving voltage signals, based on the comparison result to allow the velocity of the moving body to be closer to the predetermined velocity.

    摘要: Transmission images are obtained by radiating X-rays having two different energy levels onto a subject in one direction, and then transformed into logarithmic images, respectively. From these logarithmic images, a contrast ratio due to the two kinds of X-rays having different energies is obtained. From this contrast ratio, the term relating to the thickness of the subject is eliminated, thereby providing information only relating to the quality of the material. By collating the information with the previously measured data of materials, the material of the subject is identified.
