摘要： In a video tape recorder of the helical scan type, a pair of rotary magnetic heads for the audio signal are provided in addition to the rotary video heads so that the audio signal is recorded on the same slant track as of the video signal on a multiplex basis. The audio head pair is provided with an azimuth angle with opposite polarities from each other and different in value from that of the video head pair. The system has a first operation mode of the standard tape speed and a second operation mode in which the tape is fed at a speed, for example, 1/3 the standard tape speed. The audio and video head pairs are disposed on lines intersecting at right angles with an offset of T.sub.1 /2+T.sub.1 provided in the axial direction of rotation between the two magnetic head pairs, where T.sub.1 is the track pitch of the recording track formed on the tape in the second operation mode. The system produces overlapping tracks for the audio and video signals on the magnetic tape. In the first operation mode, the recording track is formed by a combination of magnetic heads providing an increased difference of azimuth angles between the audio and video heads, while in the second operation mode, the track is formed by a combination of magnetic heads providing a decreased difference of azimuth angles between the audio and video heads.

摘要： A permanent magnet electric machine such as, for example, a motor or generator, including a permanent magnet field member, an armature having salient magnetic poles and armature windings. A greatest common division of the number of magnetic poles of the field member and the salient magnetic poles having the armature windings differs from the number of magnetic poles. A group of grooves is formed between the salient magnetic poles having an interval of 2/3M.pi., with M being an integer which is not a multiple of three. To reduce the occurrence of cogging torque, auxiliary grooves are provided on the surface of the salient poles at positions which are spaced apart from positions of the grooves by (.pi./3)K+(.pi./6), in terms of electrical angle, with K being an integer.
