摘要： PROBLEM TO BE SOLVED: To grasp the location of a rotator in the circumferential direction with high accuracy and eliminate magnetic effects to another track.
SOLUTION: In a polarized area formed in the outer circumferential part of the rotator 11, different magnetic poles are arranged alternately along the circumferential direction, and comprise a recording polarized part 11a formed in part over the whole circumference of the outer circumferential part. By magnetically detecting point in a track which contains the recording polarized part 11a, this rotation sensor determines whether the detected point is a point on the recording polarized part 11a or a point which is not on the polarized area. By narrowing the interval between the adjacent magnetic poles on the recording polarized part 11a, the polarized area becomes an aggregate of relatively fine magnetic poles to weaken magnetic forces.

摘要翻译：要解决的问题：以高精度掌握旋转器在圆周方向上的位置，并消除对另一个轨道的磁效应。解决方案：在旋转体11的外周部形成的极化区域中，沿圆周方向交替设置不同的磁极，并且包括在外周部的整个圆周上形成的记录极化部11a。通过磁性检测包含记录偏振部分11a的轨道中的点，该旋转传感器确定检测点是记录极化部分11a上的点还是不在偏振区域上的点。通过缩小记录极化部分11a上的相邻磁极之间的间隔，偏振区域成为较细的磁极的聚集体，从而削弱磁力。

摘要： PROBLEM TO BE SOLVED: To provide a toilet seat lifter that reduces a burden by electrically lifting and lowering a toilet seat unit, doest not damage a driving mechanism by an overload applied during the driving of a motor in a direction of overloading making the motor lose synchronization and permits the downsizing of the driving mechanism.
SOLUTION: The toilet seat lifer 1 lifts a moveable plate 6 to which a toilet seat unit 10 is connected by transmitting the rotational driving force of a stepping motor 7 to a right slider 51 through a speed reducing wheel train 70, an output pinion 80 and a rack 53. A control means is structured so as to make a forward driving torque to drive the stepping motor 7 in the direction of overloading making the stepping motor 7 lose synchronization smaller than the reverse driving torque to drive the stepping motor 7 in the direction opposite to the direction of overloading making the stepping motor 7 lose synchronization.
