摘要： In the X-ray CT system, the X-ray detectors vary in output characteristics such as linearity, directivity and radiation quality from one detector to another. To make compensations for such irregularities, a plurality of phantoms of different absorption is prepared in the CT system according to the present invention. Namely, this plurality of phantoms is set one by one in the measuring space in the same manner as in the examination of an examinee or subject to be examined; the coefficient of X-ray absorption is determined for each of these phantoms. Further, theoretical values of absorption for each phantom are compared to the actual absorption measurements on each phantom to provide an absorption error value for each detector at differing absorption levels. The actual subject absorption value for each detector is used to pick the two error values closest to the actual value. The two error values are interpolated or extrapolated to find an error value for correcting the actual absorption value. The above method steps are advantageously implemented by one or more digital computers. The corrected subject absorption values are provided to a conventional image reconstruction device to provide the desired X-ray video image.
摘要翻译：在X射线CT系统中，X射线检测器的输出特性如线性度，方向性和辐射质量从一个检测器到另一个检测器的不同。为了对这种不规则性进行补偿，在根据本发明的CT系统中制备了不同吸收的多个体模。即，在测量空间中以与检查对象或被检查对象相同的方式一个接一个地设置多个幻影，确定每个这些幻影的X射线吸收系数。此外，将每个体模的吸收的理论值与每个体模上的实际吸收测量进行比较，以在不同吸收水平下为每个检测器提供吸收误差值。每个检测器的实际物体吸收值用于选择最接近实际值的两个误差值。两个误差值进行内插或外插，以找到用于校正实际吸收值的误差值。上述方法步骤有利地由一个或多个数字计算机实现。校正的被摄体吸收值被提供给常规图像重建装置以提供期望的X射线视频图像。

摘要： An ultrasonic motor is provided in which a detector will detect the amplitude of a traveling wave generated on the stator. An oscillator approximates frequency of the travelling wave with respect to the resonance frequency of the stator while the amplitude of the traveling wave is decreased. If the oscillator approaches the frequency of the traveling wave to the resonance frequency of the stator, the amplitude of the traveling wave can be maintained against increasing pressure of the increased torque load of the ultrasonic motor.

摘要： A fuel cell has a plurality of unit cells each including electrodes sandwiching an electrolyte membrane in-between, and a plurality of separators (3) each arranged between the unit cells. Each separator (3) has a plurality of contact lugs (65, 75) facing the electrodes and contacting the electrodes at pre-set contact widths and a plurality of fluid ducts (6a, 7a) each having a space between neighboring ones of the contact lugs (65, 75) as a duct width. The contact width of the contact lugs 65 (75) on a side closer to a fluid outlet is set smaller than that of the contact lugs 65 (75) on a side closer to a fluid inlet. Diffusion of an active material in an active material containing fluid into the inside of electrodes on a downstream side of a fluid duct, that is on a side closer to a fluid outlet, is facilitated.

摘要： An ultrasonic motor is provided with a moving member and a vibrating member which is in contact with the moving member so as to provide the drive input for the moving member. A piezoelectric vibrator is attached to one side of the vibrating member and the opposite side of the vibrating member has a plurality of circumferentially arranged projections. A top section of each projection contacts the moving member. The piezoelectric vibrator will generate a travelling wave on the vibrating member when a proper alternating current electrical power source is applied to the vibrating member. The vibrating member would then be oscillated in a tangential direction, a normal direction, and a radial direction. The oscillations along the tangential direction and the normal direction generate the travelling wave and only the oscillation along the tangential direction is related to the rotational speed of the moving member. The moving member will then rotate faster and provide a greater amount of output energy if the amplitude of the oscillation along the tangential direction is increased. A ratio is established between the width of the contact portion and the width of the vibrating member. When the ratio of the widths is established in a predetermined range, the efficiency of the ultrasonic motor is improved.
摘要翻译：超声波马达设置有移动构件和与移动构件接触的振动构件，以便为移动构件提供驱动输入。压电振动器安装在振动元件的一侧，并且振动元件的相对侧具有多个周向布置的突起。每个突起的顶部与移动构件接触。当适当的交流电源施加到振动部件时，压电振动器将在振动部件上产生行波。然后，振动构件将沿切线方向，法线方向和径向振动。沿着切线方向和法线方向的振荡产生行波，只有沿着切线方向的振荡与移动件的旋转速度有关。如果沿着切线方向的振荡的幅度增加，则移动构件然后将更快地旋转并且提供更大量的输出能量。在接触部分的宽度和振动部件的宽度之间建立一个比例。当宽度的比例确定在预定范围内时，提高了超声波马达的效率。

摘要： A fuel cell that includes an anode-side diffusion layer, an anode-side catalyst layer, an electrolyte membrane, a cathode-side catalyst and a cathode-side diffusion layer layered in that order. The anode-side catalyst layer includes Pt—Ru catalyst. A catalyst layer portion of the anode-side catalyst layer apart from the electrolyte membrane and/or the anode-side diffusion layer contains a metal element which is lower in standard potential than Ru and higher in standard potential than hydrogen. The metal element which is lower in standard potential than Ru and higher in standard potential than hydrogen is at least one element which may be selected from, for example, Cu, Re and Ge. By this structure, both prevention of poisoning of Pt—Ru catalyst by CO and prevention of contamination of an electrolyte membrane can be satisfied.
