    • A brushless three-phase synchronous generator includes a stator having primary generating windings and stator excitation windings whose number of poles is odd-number times the number of poles of the primary generating windings. The generator further includes a cylindrical rotor on which a plurality of field windings are wound in a full-pitch concentrated winding form. The plurality of field windings are respectively short-circuited by the corresponding diodes. A plurality of field windings in which voltages of the same phase are induced based on the odd-order spatial higher harmonic magnetic fields are connected in parallel and further connected in parallel to the central field windings which effectively produce primary field magnetic fluxes. A circulating rectifier element is connected in parallel to the central field windings. Improvement in the waveforms of the primary magnetic fields can be achieved and self-excitation in the case where the single-phase loads are connected can be prevented from occurring while magnetic coupling of the rotor field windings to the spatial higher harmonic components of the armature reaction magnetic fields is effectively maintained well.

    • On a stator core, there are wound primary generating windings of four (4) poles with a distributed full-pitch winding structure and stator excitation windings with a concentrated full-pitch winding structure, having the number of poles odd-number times the number of poles of the primary generating windings, that is, twelve (12) poles. The primary windings appropriately produce spatial higher harmonic components of the armature reaction magnetic fields. The excitation windings are connected to the center taps of the primary windings through a control rectifier. On a rotor core, six field windings of four poles. The field windings are arranged at positions where they are magnetically coupled with both static magnetic fields produced by the stator excitation windings and odd-order spatial higher harmonic components of armature reaction magnetic fields produced by the currents in the primary generating windings. The field windings are short-circuited by the diodes, respectively. In the brushless self-excited synchronous generator, the number of slots in each of the rotor and stator can be determined irrespective of the order number of the spatial higher harmonic components of the armature reaction magnetic fields. The generator is simple and rigid in its structure.

    • On a stator core, there are wound T-connection primary generating windings such that the second and third single-phase windings are respectively arranged at positions electrically orthogonal to the first single-phase winding. The winding number of the first single-phase winding is 31/2 times that of the second single-phase winding or the third single-phase winding. The stator excitation windings are also wound on the stator core, which are connected to the center taps of the primary generating windings through a control rectifier. A plurality of field windings are wound on a rotor core. The field windings are arranged at positions where they are magnetically coupled with both the odd-order spatial higher harmonic components of armature reaction magnetic fields produced by currents flowing in the primary generating windings and the static magnetic fields produced by current flowing in the stator excitation windings. Due to the T-connection primary generating windings, the generator is capable of simultaneously generating not only the three-phase outputs but also the single-phase three-line outputs.

    • A piezoelectric resonator is provided which is capable of acquiring an excellent Q characteristic while letting a film thickness of an upper electrode be larger. The piezoelectric resonator has a lower electrode and an upper electrode with a piezoelectric film being sandwiched between them. By applying a voltage between the lower and upper electrodes to let a bulk acoustic wave propagate through inner portions of the piezoelectric layer, a signal having a specified resonant frequency is obtained. The standing wave has a first wave loop at an interface on a side opposite to the piezoelectric film of the upper electrode and a wave node and a second wave loop in inner portions of the upper electrode directing from the interface toward the piezoelectric film. The film thickness of the upper electrode obtained when a wavelength of a standing wave is defined as “λ” is 0.4λ to 0.7λ.
