Abstract: A rotor includes magnetic pole portions and first and second ferric core portions. The first and second ferric core portions are each located between magnetic pole portions in the circumferential direction of a rotor. A first gap is formed between the first or second ferric core portion and a magnetic pole portion at a first circumferential side. A second gap is formed between the first or second ferric core portion and the magnetic pole portion at a second circumferential side. The first gap has a smaller width than the second gap at the first ferric core portion. The first ferric core portion is inclined toward the first circumferential side. The first gap is larger than the second gap at the second ferric core portion. The second ferric core portion is inclined toward the second circumferential side.

Abstract: A hexacene derivative is described, being expressed by formula (1): wherein X1-X6 denote the presence or absence of a carbonyl bridge [—C(?O)—], with a proviso that at least one of X1-X6 is a carbonyl bridge while any six-member ring absent of a carbonyl bridge is aromatic. A method for forming hexacene is also described, including: thermally treating the hexacene derivative to expel volatile units of CO from the hexacene derivative.

Abstract: In a shift lever device, a first engagement portion or a second engagement portion of a shift lever is inserted into a first stopping hole or a second stopping hole of a strength gate when the shift lever is turned along a manual transmission hole, thereby stopping the shift lever from turning towards an automatic transmission hole side. In the shift lever, the first engagement portion and the second engagement portion are disposed at the vehicle front side and the vehicle rear side of a support body. An increase in size of the shift lever in the vehicle left-right direction due to the first engagement portion and the second engagement portion can accordingly be suppressed, and the turning rage of the shift lever in the vehicle left-right direction can be made smaller, thereby enabling a reduction in size of the shift lever device in the vehicle left-right direction.

Abstract: In a strength gate of a shift lever device, a shift hole is provided with an automatic transmission hole, a manual transmission hole, and a communication hole. The strength gate is provided with a peninsular portion that is adjacent to the automatic transmission hole, the manual transmission hole and the communication hole, and an opposing portion that is on the opposite side of the manual transmission hole to the peninsular portion. The peninsular portion is disposed to a front side with respect to the opposing portion. A reduction in the size of the peninsular portion along the vehicle left-right direction can accordingly be suppressed even if the strength gate is reduced in size along the vehicle left-right direction, thereby enabling a reduction in the strength of the peninsular portion to be suppressed.

Abstract: A controller for use with a motor including a stator, around which three-phase coils are wound, and a rotor, which includes a magnet functioning as a first magnetic pole and a salient pole of a core functioning as a second magnetic pole. The controller supplies the three-phase coils with excitation currents having a predetermined phase difference from one another to drive and rotate the rotor. The controller includes a current adjustment unit that adjusts a fundamental wave current using high-order currents for third order and ninth order components in a q-axis to reduce torque ripple. The excitation current is generated based on the fundamental wave current adjusted by the current adjustment unit.

Abstract: A brushless motor includes a rotor and a stator. The rotor is provided with a rotor core including a plurality of magnet poles and a plurality of core poles. A void is formed at a boundary between each core pole and an adjacent magnet pole in the circumferential direction. Each magnet pole includes a peripheral core portion located closer to the stator than the magnet in the radial direction of the rotor. The void formed in at least one of two circumferential sides of each magnet pole includes an extended void region that extends into the peripheral core portion toward a middle point of the magnet pole in the circumferential direction.

Abstract: A network management system allowing traffic data collection not to overload switching equipment is disclosed. A schedule table has a plurality of entries, in which traffic data collection events for respective ones of traffic counters arc distributed at intervals. A traffic data collection processor sequentially accesses the entries of the schedule table and, when a traffic data collection event is registered in an accessed entry, a traffic data collection request is transmitted to a corresponding traffic counter.
