It is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible.A stator 6 includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles 6a, 6b, 6c. The stator magnetic poles 6a, 6b, 6c are each composed of an arcuate stator core 13 having a plurality of axially extending claw poles 16b and a circumferentially elliptically wound stator winding 14. The stator magnetic poles 6a, 6b, 6c are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles 6a, 6b, 6c can improve a cooling effect.

An AC generator comprises a rotor and a stator having a three-phase winding. A three-phase inverter is connected to the three-phase winding. Here, the three-phase winding comprises at least two independent three-phase windings. Switching elements for respective phases of the three-phase inverter are connected in parallel by the number of the independent three-phase windings, and in-phase windings are individually connected to their parallel switching elements.

When an input vocabulary is stored in advance in a pronunciation dictionary unit, a phoneme sequence correlated with the input vocabulary is acquired from the pronunciation dictionary unit and a dictionary code indicating that the acquisition source is the pronunciation dictionary unit is generated. When the input vocabulary is not stored in advance in the pronunciation dictionary unit, a phoneme sequence of the input vocabulary is generated by a pronunciation generation unit and a generation code indicating that the acquisition source is the pronunciation generation unit is generated. Then, a recognition grammar model in which the phoneme sequence of the input vocabulary is correlated with the dictionary code or the generation code of the input vocabulary is stored and a recognition parameter is generated.

A multi-beam scanning optical device uses optical fibers to transmit the laser fluxes from the semiconductor lasers. The optical fibers are arranged such that point light sources formed at respective exit ends of the optical fibers are linearly aligned. The exit light fluxes from the optical fibers are deflected by a polygon mirror and converged on an image surface to form a line of beam spots, which forms plurality of scanning lines per scan. In order to adjust the angle of the line of beam spots, the exit end portions of the optical fibers is fixed to a fiber alignment block such that the exit end surfaces of said optical fiber are linearly aligned on an alignment line. Further, the fiber alignment block is fixed to a cylindrical member which is rotatably supported by a supporting member. Accordingly, the angle of the line of beam spots can be easily adjusted by rotating the cylindrical member.
