    • In a magnetic disk apparatus such as a Winchester drive, a head position control mechanism is provided for locking the transducer head on a noneffective surface region of the magnetic disk, where no data is to be stored, as when the apparatus is powered off. A locking lever pivots in a plane parallel to the disk plane for movement into and out of locking engagement with a rotary member rotatable jointly with the head arm about a common axis. A solenoid holds the locking lever out of locking engagement with the rotary member during the progress of data transfer between disk and head. Upon completion of the data transfer, or when the apparatus is electrically turned off, the solenoid becomes deenergized, permitting the locking lever to be sprung into locking engagement with the rotary member. Then the head arm transports the head to, and allows the same to land on, the noneffective surface region of the disk. The head is locked in that position as long as the locking lever remains in locking engagement with the rotary member.
    • 在诸如温彻斯特驱动器的磁盘装置中,提供了一种头位置控制机构,用于将换能器头部锁定在磁盘的无效表面区域上,其中不存储数据,如同设备断电时一样。 锁定杆在与盘平面平行的平面中枢转,用于与与头臂围绕公共轴线共同旋转的旋转构件移动进入和离开锁定接合。 在盘和头之间的数据传送过程中,螺线管将锁定杆保持与旋转构件的锁定接合。 在完成数据传送时,或者当设备电气关闭时,螺线管变为断电状态,允许锁定杆与旋转构件锁定接合。 然后,头臂将磁头传送到磁盘的无效表面区域,并允许其同时到达。 只要锁定杆保持与旋转构件锁定接合,头部被锁定在该位置。

    • Disclosed is a strands protector which comprises a U-shaped housing having a three-dimensionally bent bottom wall and side walls upstanding from the bottom wall, and a cover member connected by a hinge to the housing to close the opening of the housing and releasably secured to the housing by locking means. The cover member includes a hinge at a position corresponding to the location of the bent portion of the bottom wall of the housing.Also disclosed is a locking mechanism which comprises a locking arm provided on one of two hinge-connected members and an arm-engaging receptacle provided on the other member. The locking arm has an end projection adapted to be inserted in a central hole of the receptacle to secure the two members together, and the receptacle has a projection insertion cutout at a position where interference occurs between the projection of the locking arm and the receptacle when one of these two members is superposed on the other.
    • 公开了一种股线保护器,其包括具有三维弯曲的底壁和从底壁直立的侧壁的U形壳体,以及通过铰链连接到壳体以封闭壳体的开口并且可释放地固定的盖构件 通过锁定装置到壳体。 盖构件在与壳体的底壁的弯曲部分的位置对应的位置处包括铰链。 还公开了一种锁定机构,其包括设置在两个铰链连接构件中的一个上的锁定臂和设置在另一个构件上的臂接合插座。 锁定臂具有适于插入插座的中心孔中的端部突起,以将两个部件固定在一起,并且插座在位于锁定臂的突起与插座之间发生干扰的位置处具有突出插入切口, 这两个成员之一叠加在另一个上。

    • In a data transfer apparatus such as a Winchester disk drive wherein a transducer or transducers fly over a magnetic disk surface or surfaces during data transfer therewith, a retractor mechanism is provided which coacts with a transducer positioning mechanism for causing the transducer to land on a head landing track disposed radially and inwardly from a series of concentric data storage tracks on the disk, as when the apparatus is electrically turned off. The retractor mechanism includes a spring or like energy storage element in which energy is stored when, with the apparatus powered on, the transducer is first transported by the positioning mechanism from the head landing track to the outermost home track on the disk for initialization. The spring is locked, as under the force of a solenoid, against the release of the stored energy during the subsequent run of data transfer, making it possible for the positioning mechanism to transport the transducer from track to track without being loaded by the deflected spring. When the apparatus is powered off, the solenoid unlocks the spring for releasing the stored energy and hence for returning the transducer to the landing track.
    • 在诸如温彻斯特磁盘驱动器之类的数据传送装置中,其中换能器或换能器在数据传送期间在磁盘表面或表面上飞行,提供牵开器机构,其与换能器定位机构共同作用,以使换能器落在头部 登陆轨道从磁盘上的一系列同心数据存储轨道径向向内设置,如同该设备电气关闭时一样。 牵引器机构包括弹簧或类似的能量存储元件,其中当设备通电时,换能器首先通过定位机构从头部着陆轨道传送到盘上的最外面的归属轨道以进行初始化。 弹簧在螺线管的力作用下被锁定,以防止在随后的数据传送过程中释放储存的能量,使得定位机构可以将传感器从轨道传输到轨道,而不会被偏转的弹簧 。 当设备断电时,螺线管释放弹簧以释放存储的能量,并因此使换能器返回到着陆轨道。
