Abstract: The present invention has an object to provide a rotating mechanism with a very high rotation efficiency in which rotation resistance is reduced and rotation is encouraged. It comprises a fixed member having bearings and a rotary member including a rotary shaft journalled by the bearings and a disk member fixed on the rotary shaft. A plurality of coils is mounted on the fixed member and arranged at regular intervals on a circle centered on the rotary shaft, and first permanent magnets are mounted on the disk member, arranged at regular intervals on a circle centered on the rotary shaft and arranged to face the coils.

Abstract: The present invention has an object to provide a rotating mechanism with a very high rotation efficiency in which rotation resistance is reduced and rotation is encouraged. It comprises a fixed member (1) having bearings (16, 18); a rotary member (2) including a rotary shaft (21) journalled by the bearings and a disk member (22) fixed on the rotary shaft; a plurality of coils (3) which are mounted on the fixed member (1) and arranged at regular intervals on a circle centered on the rotary shaft (21); and a first permanent magnet (4) mounted on the disk member (22), wherein first permanent magnets (4) are arranged at regular intervals on a circle centered on the rotary shaft (21) and arranged to face the coils (3).

Abstract: In a coating device using mist-blowing technique, a primary spray (3) injects a liquid to produce original mist. Supplied with the original mist, a mist box (2) produces a fine mist having a very small particle size. A secondary spray (5) is connected to the mist box and sprays the fine mist towards a workpiece.
