    • PURPOSE:To raise the mechanical strength of winding and insulating material at the time of operation by raising adhesion with conductor by the procedure in which a resin-treated fibrous base material is wound around the innermost layer of winding conductor and then its outside layer is wound with an insulating material and subjected to hot forming treatment. CONSTITUTION:The resin-treated fibrous base material 5, e.g., glass cloth, glass unwoven fabric, etc., is wound around the conductor 2, its surface is wound with the pre-preg polyimide film 3, and then its surface is further wound with the pre- preg mical tape 4 into a definite turn to form the winding 1. The formation of such a winding insulated layer increases greatly the adhesion between the conductor 2 and the pre-preg polyimide film 3, thus preventing the winding insulated layer from exfoliation due to mechanical stress during operation and also raising electric characteristics.

    • PURPOSE:To make easier the confirmation of void dimension insoldered portion by providing the projection of connecting piece for connecting conductor on the side of conductor in an exposed state. CONSTITUTION:The long scale conductor 3 is connected through the connecting piece 4, the projection of which is formed of part of conical base and has a sectional diameter smaller than the large dimension and larger than the smaller dimension of the width or height of the section of the conductor 3. Accordingly, when the shape of the concaved portion in the joint on the conductor 3 is machined to the shape of the projection of the connecting piece 4, a structure is formed that part of the projection of the connecting piece 4 is exposed on the side of the long conductor 3 when the conductor 3 is jointed with the connecting piece 4. Thus, the confirmation of void dimension in portion to be soldered can be easily made at the time of soldering, and also the air in the voids can be easily expelled to the outside at the time of soldering, thus preventing the occurrence of voided defects in the soldered portion.

    • PURPOSE:To achieve an economical manufacture with a limited number of jigs, by a method wherein only a part containing a bottom surface or a side wall of a spiral groove is machined and assembled at a required dimensional accuracy with respect to a doughnut-shaped winding frame to allow a manufacture at a consistent dimensional standard. CONSTITUTION:A winding frame 5 is wound with a band-shaped bend piece 1a at a specified position on the basis of the small doughnut-shaped winding frame 5 with a radius thereof smaller than a spiral groove to be formed by the band-shaped bend piece 1a of a discharge tube and joined monolithically by welding. Under such a condition, an outer diameter side of the band-shaped bend piece 1a, namely, the bottom surface of the spiral groove is machined to specified shape and dimensions to adjust. A coil guide 6 which is divided in a size detachably easy to handle and machined to specified dimensions and shape is mounted on the winding frame 5. In this manner, a conductor is wound sequentially to produce a helical coil 2. A band-shaped bend piece 1c is welded on a band-shaped bend piece 1b to assemble a discharge tube. After a deformation caused by welding of the discharge tube is corrected, the winding frame 5 is taken into pieces and carried out from the inside of the discharge tube to dismantle.
