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： Radiation transmission intensity information obtained from a radiation source of two different energy levels or energy bands is used to perform an energy subtraction calculation and quantify the constituent substances of the object being analyzed. The objective is to simultaneously detect and quantify the plural substances composing the object being analyzed in a single operation using a single subtraction calculation equation. An energy subtraction calculation is first performed to eliminate a specific substance in the object being analyzed, making it possible to simultaneously determine the other two constituent substances using the negativity of the calculated result. When three substances are overlapping in the direction of radiation transmission, using the transmission intensity information from a radiation source with only two energy levels, the effect of one substance is eliminated while identifying and quantifying the other two by applying an energy subtraction calculation process that eliminates the first substance and obtains the density of a third substance, and obtains the density of the third substance in an area where the three substances overlap based on the calculated result for the area containing the first and second substances.

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.

摘要： Disclosed are a radiation detector and a method of manufacturing the same. The radiation detector includes a radiation screening member for cutting off radiation incident upon the marginal portions of the radiation incident surface of a semiconductor radiation sensor or a semiconductor radiation sensor array for outputting pulses in correspondence with radiation photons, as well as upon the boundary portions between adjacent sensors. In order to manufacture such a radiation detector, leads are provided by the wire bonding, soldering or bump contacting on the radiation screening member, and at least part of the radiation screening member is then fitted to the semiconductor radiation sensor or the semiconductor radiation sensor array so as to make it electrically connected to the electrodes of the semiconductor radiation sensor or the semiconductor radiation sensor array.
