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.

An automatic specimen sealing system which provides totally automated sealing of glass slides. Slides are ejected sequentially at predetermined intervals onto a conveyor at a predetermined orientation. The size of the specimens held on the slides is detected, and liquid adhesive is supplied onto the slides in an amount determined in accordance with the thus-detected specimen sizes. Glass covers are then placed over the specimens, with the size of the glass covers being also selected in accordance with the specimen size. The slides with the covers placed thereon are next fed to a binding device where the covers and slides are bound together. Finally, the slides are assembled in trays.
