Abstract: A permanent magnet rotating electric machine uses no skewing under a predetermined current and voltage condition to prevent torque from decreasing and to decrease pulsation torque to make the machine less vibrating and less noisy. The permanent magnet rotating electric machine includes a stator with multi-phase stator windings and a rotor with a plurality of permanent magnets internally embedded in a rotor core. The core shape of the rotor is uniform in the depth (longitudinal) direction with no skewing in the arrangement of the permanent magnets. The permanent magnets are symmetrical with respect to the rotation direction, but irregular with respect to the depth direction, for each pole. A magnetic flux generated from the between-pole permanent magnets almost equals a magnetic flux generated from the pole-center permanent magnet.

Abstract: A portable terminal providing TV broadcast reception functionality, that achieves reduced power consumption. A CPU controls lighting of a back light via a back light control part. The CPU controls a CM identifier detection part to detect a commercial identifier from the demodulated signal of the TS of a broadcast wave received in real time by a portable terminal or from the demodulated signal of the TS from a replay data holding part. The result of this detection operation is stored in a memory part. A decision is made as to whether the start time of commercials has arrived from the detected result as read compared to the current time. If the time to start commercials has arrived a back light stops lighting and this discontinuance of lighting continues until the end time of the commercials. When the end time of the commercials is reached the back light lights again.

Abstract: A permanent magnet type electric rotating machine comprises a stator having a salient-pole concentrated winding, and a rotor disposed with a rotational gap, and having a plurality of permanent magnets arranged and fixed in a circumferential direction inside, and an auxiliary salient pole provided between the permanent magnets. A ratio of the number of poles for the rotor and the number of slots for the stator is 2:3 and, when a slot pitch of the stator is ?s (electrical angle), an angle ? (electrical angle) made by a circumferential width of the permanent magnet in the surface of the stator side with an axis of the rotor is set at ??n×?s/2+8×m (n=1 or 2, and m=1, 2 or 3). Thus, pulsation torque, cogging torque or the waveform distortion of a no-load induced voltage is selectively reduced as occasion demands.
