    Abstract: A first magnetic substance and a second magnetic substance are arranged opposite to each other with a gap left therebetween; a holding member being arranged in the gap; a magnetic field generator being secured to the holding member; the generator being arranged adjacent to the first magnetic substance or the second magnetic substance, thereby increasing an magnetic attraction generated by a magnetic force between the generator and the first magnetic substance or the second magnetic substance. A slide between a sliding portion of a supporting member and that of the holding member is permitted only on the magnetic substance side to which the magnetic field generator stands close, which relaxes the requirements of dimensional accuracy such as the height of the holding member.

    Abstract: When it is judged that a driven body reaches vicinity of a target position, a present phase of the passing current is not switched to keep a state of the passing current even if a phase of a passing current needs to be switched judging from the position of permanent magnet rotor thereby a stabilizing of torque can be attained.

    Abstract translation: 当判断为驱动体到达目标位置附近时，即使通过电流的相位需要切换，也不会切换通过电流的当前相位，以保持通过电流的状态， 永磁转子由此可实现转矩的稳定。

    Abstract: An exhaust gas recirculation system capable of regulating the degree of valve opening with high accuracy in order to properly recirculate exhaust gas to the combustion chamber (1a) of a four-cycle engine (1) for automobiles even in the case of the diesel turbo-type car which usually generates high temperature and pressure exhaust gas. In the exhaust gas recirculation system disclosed herein, two closure valves (19, 20) are provided on the movable shaft (23) so that exhaust gas can flow into a movable space (10a) through openings formed by the movement of the two closure valves (19, 20) in their movable range. The pressure effecting on the two closure valves (19, 20) is canceled out and the movement of the movable shaft (23) is not prevented by high pressure of the exhaust gas. Therefore, even in the case of high temperature and pressure exhaust gas of the diesel turbo-type car or like vehicles, the movable shaft can be driven accurately with a relatively small power stepping motor (17).

    Abstract translation: 一种排气再循环系统，其能够高精度地调节开阀程度，以便即使在柴油机涡轮增压器的情况下也能将废气适当地再循环到用于汽车的四冲程发动机（1）的燃烧室（1a） 通常产生高温高压废气的汽车。 在本文所公开的排气再循环系统中，两个闭合阀（19,20）设置在可动轴（23）上，使得废气可以通过由两个闭合阀的运动形成的开口流入可移动空间（10a） （19,20）处于可动范围。 抵消对两个关闭阀（19,20）的压力被消除，并且通过排气的高压不能防止可动轴（23）的移动。 因此，即使在柴油涡轮式车辆等车辆的高温高压排气的情况下，也可以用相对较小的动力步进电机（17）精确地驱动可动轴。

    Abstract: A metallic member 22 is integrated with a molded rotor 12, and a bearing 16 is held to the rotor 12 through this metallic member 22. At that time, a washer 24 is secured to the metallic member, and the rotating portion of the bearing is held by this washer, thereby improving holding property and durability of the bearing. A stopper plate 21 for limiting the displacement of the output shaft of a motor is used as the metallic member, thereby enabling holding property and durability of the bearing to increase without increasing the number of components. The base-end side of the metallic member 22 is integrally in-mold molded with the rotor 12, which enables the metallic member 22 to be firmly held.
