    • An electric motor comprising an inner periphery side rotor provided with inner peripheral permanent magnets with unlike poles, which are disposed alternately along a circumferential direction of the inner periphery side rotor, an outer periphery side rotor provided with outer peripheral permanent magnets with unlike poles, which are disposed alternately along a circumferential direction of the outer periphery side rotor, and a rotating device that varies a relative phase between the inner periphery side rotor and the outer periphery side rotor by rotating at least the inner periphery side rotor or the outer periphery side rotor around the rotational axis. The outer peripheral side rotor is arranged such that a rotational axis thereof is coaxial with a rotational axis of the inner periphery side rotor. The rotating device sets a variable width of the relative phase between the inner periphery side rotor and the outer periphery side rotor within a range of an electrical angle of below 180°.

    • A control system for internal combustion engine installed in vehicle with automatic transmission which lowers the engine output torque for reducing the shock apt to be felt by the passengers of a vehicle equipped with an automatic transmission at the time of shifting gears. The clutch speed ratio between the transmission input and output shafts is calculated to compare with a first value. If the ratio goes beyond the first value, engine output torque is reduced by a first amount. Then the ratio is compared with a second value and if the ratio comes within the second value, the torque is further reduced by a second amount which is greater than the first amount. The ratio is continuously calculated and is again compared with a third value. When the ratio comes within the value, the torque is restored to the first reduction amount. The ratio is finally compared with the fourth value and if it comes within the value, the torque is fully restored to the initial state. Thus, the gear shift shock is avoided and as a secondary effect, clutch wear is reduced.
    • 一种安装在具有自动变速器的车辆中的用于内燃机的控制系统,其降低发动机输出扭矩,以减少在换档时配备有自动变速器的车辆的乘客易于感觉到的冲击。 计算出变速器输入轴和输出轴之间的离合器速度比与第一个值进行比较。 如果比率超过第一值,则发动机输出扭矩减小第一量。 然后将该比率与第二值进行比较,并且如果该比率在第二值内,则转矩进一步减小大于第一量的第二量。 该比率被连续计算并且再次与第三值进行比较。 当该比值在该值内时,扭矩恢复到第一减小量。 该比值最终与第四值进行比较,如果达到该值,则扭矩完全恢复到初始状态。 因此,避免了换档冲击,并且作为次要效应,减少了离合器磨损。
