Abstract: A rotating electrical machine includes a stator and a rotor, the rotor includes a rotor core and a plurality of magnetic poles, the plurality of magnetic poles includes a plurality of magnet poles formed by permanent magnets, and a plurality of dummy poles, the magnet poles and the dummy poles are alternately disposed in both an axial direction and a circumferential direction, non-magnetic holes are provided between the magnet poles and the dummy poles that are adjacent in the axial direction, and when a length of each magnet pole in the axial direction is tm, a length of each dummy pole in the axial direction is tc, a length of each non-magnetic hole in the axial direction is ta, and a length of the rotor core in the axial direction is lc, the rotating electrical machine satisfies tm>tc and lc<(2×tm)+ta.

Abstract: A speech synthesis device includes a memory for storing speech information at a plurality of memory locations with each location commencing at a respective leading address, and a table of leading addresses is maintained in the memory. At the beginning of operation, the leading addresses are read from the table and stored in a random access memory so that the leading addresses can be selectively accessed by keyed in information. Address generation circuitry will then successively address the data in each information area of memory in reponse to a particular accessed leading address.
