    • A method of measuring a profile of an object wherein an ultrasonic wave is radiated from an ultrasonic transducer toward an object supported by a supporting member in the water filled in a water tank, and a wave reflected at the surface of the object is detected by the transducer, and an apparatus for carrying out the method. A traversing device moves the transducer sequentially to a plurality of measurement points on an arc equidistant from a predetermined rotational center while opposing the transducer to the predetermined rotational center. A supporting device moves the supporting member relative to the transducer and sets the object in the predetermined position under water. A control device delivers a drive signal to the traversing device to move the transducer sequentially to the measurement points, causes the transducer to radiate an ultrasonic wave when the transducer is in each of the measurement points, calculates a distance between the transducer and the surface of the object in accordance with a difference between the time the transducer radiates the ultrasonic wave and the time transducer receives the wave reflected at the surface of the object, calculates coordinates of each of the measurement points, and coordinates of the surface of the object corresponding to each of the measurement points from the calculated distance, and obtains the profile of the object from the calculated coordinates of the surface of the object at each of the measurement points.

    • Diclosed are a fluid mixing element in which at least one helical shaft provided with at least one helical groove on an outer peripheral wall thereof throughtout its length is inserted in a cylindrical passage tube provided with at least one helical groove on an inner peripheral wall thereof throughout its length.According to the mixing element of the present invention, the fluid supplied into the mixing element flows partly along the helical groove formed in the passage tube and partly along the helical groove formed on the helical shaft to produce the turbulent mixing of the fluid in the mixing element. When the fluid flows through the helical grooves formed in the passage tube and on the helical shaft of the mixing element, the phase transfer is also carried out at planes perpendicular to the flow direction by inertia of the fluid. Accordingly, the fluid in contact with the helical grooves and the fluid out of contact therewith are replaced with each other in series. The mixing is further effected by division of the fluid in series at each of many contact portions of the passage tube and the helical shaft.As a result, the fluid mixing efficiency can be improved. The number of the mixing elements is therefore reduciable, when the plural mixing elements are connected to each other to form the mixer, and in addition, the time required for mixing in the mixer is also reducible.
    • 密闭式是一种流体混合元件,其中至少一个螺旋轴在其外周壁上至少有一个螺旋槽穿过其长度被插入到一个圆柱形通道管中,圆柱形通道管在其内周壁上设有至少一个螺旋槽 它的长度。 根据本发明的混合元件,供给到混合元件中的流体部分地沿着形成在通道管中的螺旋槽流动,部分地沿着形成在螺旋轴上的螺旋槽流动,以在混合中产生紊流混合 元件。 当流体流过形成在通道管中的螺旋槽和混合元件的螺旋轴时,相位转移也通过流体的惯性在与流动方向垂直的平面处进行。 因此,与螺旋槽接触的流体和与其不接触的流体被相互替换。 进一步通过在通道管和螺旋轴的许多接触部分中的每一个处分离流体来进行混合。 结果,可以提高流体混合效率。 因此,当多个混合元件彼此连接以形成混合器时,可以减少混合元件的数量,此外,混合器中混合所需的时间也可以减少。
