摘要： An index signal is used for assuring media for use in a floppy disk drive to be exchangeable with each other. While the signal is output once for each rotation of a spindle motor, since the signal generation is carried out in a non-contact manner with rotating members including the medium, a hole sensor or the like has been previously used. However, such a hole sensor is expensive and fragile under temperature and mechanical stress. A pulse generator has been proposed, in which the rotor magnet is provided with magnets having unequally allocated angles and disposed all along a circumference and a stator coil and is disposed so as to match with the rotor magnet to have a pulse generated once for each rotation. However, the generated signal has, been poor in its S/N characteristic. It is an object of the invention to overcome the difficulties and provide a pulse generator that is highly reliable and excellent in the S/N characteristic with the manner of allocation of angles for the rotor magnet improved. A rotor assembly having a permanent magnet with a plurality, i.e., M pieces, of magnetic poles of opposite polarities to each other alternately disposed in a circumferential direction and a stator assembly having a plurality of stator coils disposed in confronting and coaxial relationship with rotor assembly, at least one set of the magnetic poles are set to have equally allocated angles from the center of the shaft. The remaining magnetic poles are set to have unequally allocated angles. The stator coils electromagnetically match the rotor assembly only once for each rotation thereof and a very large pulse is generated. In addition, a waveform with a satisfactory S/N characteristic can be obtained.

摘要： Music contents assigned to play lists are reproduced so as to correspond to user's preference. A music content database 7 has stored a plurality of music contents. A CPU 3 creates genre ranks such that music contents that have been more frequently, for example, reproduced are more highly ranked. In addition, the CPU 3 creates play lists corresponding, for example, to tempos and stores the created play lists in a play list database 8. The CPU 3 selects a play list corresponding to a moving tempo obtained from a tempo detection section 9 and selects music content categorized as a highly ranked genre in the genre ranks from those corresponding to the selected play list. The selected music content is supplied to a decoder and amplifier section 12 and then reproduced from a head phone 14.

摘要： Content is selected on the basis of changes of a walking tempo. The walking tempo is detected (S5). In a state determination process (S7), it is determined whether the walking tempo tends to increase, be constant, or decrease. A walking tempo corrective coefficient is calculated on the basis of the determined result and a corrective walking tempo is calculated with the walking tempo corrective coefficient (S9). It is determined whether or not music is changed on the basis of the corrective walking tempo rather than the actually detected walking tempo (S11). When music is changed, relevant music content is searched. Controls are performed in such a manner that when the walking tempo is decreasing, the foregoing state is kept for a while, when the walking tempo is increasing, music is quickly selected according to the increase of the walking tempo, and when the walking tempo is stable, music is not selected.
