    • A driving apparatus of a curtain includes a field portion disposed in a curtain rail containing a curved portion. The field portion includes a yoke and a magnet group having magnetic poles disposed along the yoke alternately so that adjacent poles are different from each other and which is preferably formed of a flexible rubber magnet. There is provided a movable portion guided on the curtain rail movably and including a core base opposed to the magnet group, a plurality of cores project from the core base toward the magnet group and are integrally formed in the core base and coils are wound on a plurality of cores. Further, a commutator which switches the polarity for the movable portion is provided to form a linear motor and thereby the polarity of a dc power source for energizing the commutator is switched so that the curtain attached, at an end thereof, to the movable portion is moved along the curtain rail in one direction and the opposite direction to open and close the curtain.

    • A magnetoresistive element includes magnetoresistive films each having an upper surface and a lower surface, and conductors combining the magnetoresistive films in series and including top electrodes and bottom electrodes. Each one of the top electrodes and corresponding one of the bottom electrodes oppose each other to sandwich corresponding one of the magnetoresistive films. Each electrode of the top electrodes and the bottom electrodes includes a stem section and a branch section, the stem section extending in a direction along a series alignment direction of the magnetoresistive films, and the branch section extending along the lamination plane in a direction intersecting a direction in which the stem section extends. The branch section in the top electrode is in contact with an upper surface of the corresponding magnetoresistive film, and the branch section in the bottom electrode is in contact with a lower surface of the corresponding magnetoresistive film.
    • 磁阻元件包括各自具有上表面和下表面的磁阻膜,以及将磁阻膜串联并包括顶电极和底电极的导体。 顶部电极和对应的一个底部电极中的每一个彼此相对以夹持相应的一个磁阻膜。 顶部电极和底部电极的每个电极包括杆部分和分支部分,杆部分在沿着磁阻膜的串联取向方向的方向上延伸,并且分支部分沿着层叠平面沿与 杆段延伸的方向。 顶部电极中的分支部分与相应的磁阻膜的上表面接触,并且底部电极中的分支部分与相应的磁阻膜的下表面接触。
