A cap adapted for use as a container cover where the cap has a thermoplastic resin liner pressed formed onto the inner surface of a cap shell. The plastic liner is formed such that the difference between the intrasurface orientation index of the outer peripheral portion of the liner and the intrasurface orientation index of the central portion of the liner does not exceed 0.37 where the intrasurface orientation index is defined as the sum of the orientation coefficient of the liner in the radial direction and the orientation coefficient of the liner in the circular direction.A method of making a cap having a thermoplastic liner where the liner is press-formed into shape under conditions whereby the difference between the intrasurface orientation index of the outer peripheral portion of the liner and the orientation index of the central portion of the liner does not exceed 0.37.

A rotary electric machine includes a rotor core, a stator, a field yoke, and a field winding. The rotor core is fixed to a rotary shaft, which includes a magnetic body for forming a magnetic path, and magnetic salient poles. The stator has teeth and a stator winding wound around the teeth by concentrated winding. A slot is formed between adjacent ones of the teeth in a circumferential direction. The field yoke magnetically connects the stator and the magnetic body. The field winding is located in proximity to at least one of the winding ends of the stator winding in an axial direction of the rotary shaft. The field winding generates a magnetic pole on the magnetic salient poles when energized.

In a rotating electrical machine, when a stator winding is wound in concentrated winding, an improvement in performance is achieved by reducing a magnetomotive force harmonic without reducing a fundamental wave magnetic flux generated by a stator. A rotating electrical machine (10) includes a rotor (18), and two stators (14, 16) opposed with the rotor (18) being interposed therebetween either on both sides of the rotor (18) in the axial direction or on both sides of the rotor (18) in the radial direction. Stator windings (22) provided in a plurality of portions in the circumferential direction of each stator (14, 16) are wound in concentrated winding. The directions of magnetic fluxes generated by stator windings (22) having the same phase in the stators (14, 16) are in mutually opposite directions with respect to either the axial direction or the radial direction. The stator windings (22) having the same phase in the stators (14, 16) are arranged to be shifted from each other by 180 degrees in electrical angle in the circumferential direction.
