摘要： PURPOSE:To disperse a liquid as fine particles and perform efficient mixing by forming narrow gaps between each of a plurality of male spiral fins and an inner surface of a tube where a liquid to be mixed is to be flowed and installing the fins having opposite spiral directions alternately. CONSTITUTION:An outer tube 1 of a straight tube or a taper tube, a center shaft 5 set on the axial line of the outer tube 1, and a plurality of spiral fins 9 comprised of male spiral plates fixed in the center shaft 5 coaxially are installed. The spiral fins 9 are so installed as to have narrow gaps between each of the outer circumferences of the fins and the inner surface of the outer tube 1. The neighboring fins 9 with right hand helical winding with left hand helical winding are installed alternately and a plurality of liquids to be mixed are introduced from one end of the outer tube 1 and mixed particles are discharged from the other end. As a result, the liquids are dispersed as fine particles and mixed each other at high efficiency.

摘要： PURPOSE:To work a lens uniformly with high accuracy and to simplify post- working, by cutting a lens blank material under rotation along the curve of the lens by means of a laser beam which focuses on the diametral line of said material while moving the beam in the direction orthogonal with the optical axis thereof. CONSTITUTION:A beam irradiating body 16 is so controlled that the laser beam emitted therefrom focuses on the optical axis of a lens blank material L. A horizontal guide base 7 and a rotating device 2 are moved to bring the roll 14 at the forward end of a detection rod 13 into contact with one end of a model body M. One end of the material L is located below the body 16. The device 2 is then driven to run a revolving shaft 6 at a low speed and the laser beam is irradiated from the body 16 to the material L so that the material L is fusion cut from one end on the outside circumference thereof. When the device 2 is moved toward the center by operating a hydraulic cylinder 10, the rod 13 moves the base 7 axially along the curve of the body M; therefore, the material L is cut from the outside circumference toward the central part in the diametral direction, whereby the lens having prescribed curvature is formed.
