    • The present invention is directed to prevention of breakdown caused by electrostatic discharge in an MR element. An MR element constitutes a read element. A head support device 2 supports a magnetic head 1. A lead wire 3 is constituted with at least a pair of lead wires 31 and 32 and each of the pair of lead wires 31 and 32 is connected to the read element at one end. A terminal board 5 is provided with at least one pair of terminal conductors 52 and 53 on top of a hard substrate 51. The pair of terminal conductors 52 and 53 are provided with connecting areas 54 and 55 respectively on the same side, to which one end of which are connected the other ends of the lead wires 31 and 32 respectively. The pair of terminal conductors 52 and 53 are electrically shorted from each other by a shorting portion 56 at a rearward position which is away from the connecting areas 54 and 55 over a distance. The substrate 51 is provided with grooves or perforations 57 which facilitate the cutting operation between the shorting portion 56 and the connecting areas 54 and 55.
    • 本发明涉及防止由MR元件中的静电放电引起的击穿。 MR元件构成读取元件。 头支撑装置2支撑磁头1.引线3由至少一对引线31和32构成,并且一对引线31和32中的每一个在一端连接到读取元件。 端子板5在硬质基板51的上面设置有至少一对端子导体52和53.一对端子导体52和53分别在同一侧设置有连接区域54和55,其中一个 其端部分别连接到引线31和32的另一端。 一对端子导体52和53通过远离连接区域54和55的后方位置处的短路部分56彼此电短路。 基板51设置有槽或穿孔57,其有利于短路部分56和连接区域54和55之间的切割操作。

    • 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.
