摘要： A plurality of grooves 25 are formed in an outer peripheral surface of a cylindrical rubber magnet 17. The grooves 25 extend in a direction in which the cylindrical rubber magnet 17 is inserted into a yoke 3. The grooves 25 are open on both ends in the direction of insertion and are also open outwardly in a radial direction of the cylindrical rubber magnet 17. The grooves are formed at predetermined intervals in a peripheral direction of the cylindrical rubber magnet 17. When the cylindrical rubber magnet 17 is inserted into the yoke 3, an adhesive 15 gets into the grooves 25 without being pushed out of a lower end surface 21 of the cylindrical rubber magnet 17. The adhesive located between adjacent grooves also readily gets into the grooves 25. By presence of the adhesive got into the grooves 25, a necessary and sufficient amount of the adhesive can be uniformly interposed between a peripheral wall section 11 of the yoke 3 and the cylindrical rubber magnet 17.

摘要： A method of manufacturing a stator winding includes a twisting step of U-shaped conductor segments having a pair of straight portions by moving the straight portions in the circumferential direction while restraining the turn portions of the U-shaped conductor segments in the axial direction by a pressing tool. After the previously twisted U-shaped conductor segments are inserted into slots of a stator core, the straight portions are bent in the circumferential direction. The pressing tool is constituted of a stationary top plate that has recesses into which the straight portions are inserted and a movable top plate that is movable to close the recesses after the straight portions are inserted in the recesses.

摘要： An electromagnetic flow sensor for a fluid flowing through a pipe comprises a measuring tube which can be inserted into a pipe. The measuring tube comprises a support tube as an outer covering of the measuring tube, a tubular liner of insulating material, located in a lumen of the support tube, for conducting the flowing fluid isolated from the support tube, and an open-pore reinforcing body for stabilizing the liner. The reinforcing body is sintered directly in said support tube. A magnetic-circuit arrangement is disposed on the measuring tube for producing and guiding a magnetic field which induces an electric field in the flowing fluid. Electrodes pick up voltages from the electric field. Furthermore, the reinforcing body has coil-core seats for coil cores of the magnetic-circuit arrangement.

摘要： A method and a corresponding apparatus provide for both the automatic lacing of a toroidal coil of a stator of a dynamo-electric machine, and the knotting of the end lacing terminal of the lacing cord, by using the same needle and the same thread-guide tube. The apparatus for lacing and knotting comprises an automatic control system that, accomplished the whole lacing operation on the coil, stops the rotation movement of the stator and drives the lacing needle according to a sequence of movements in order to form a plurality of linked rings closed one on the other for obtaining a closing chain on said end lacing terminal. A particular cutting system allows not generating scrap, i.e. undesired cord portions, accelerating the production process and increasing the system reliability.
