    • A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. A head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.
    • 一种用于磁盘驱动器的头臂,包括设置在磁头和致动器之间的引导臂,以将致动器的致动力传递到磁头,从而沿着磁盘的平面引导磁头, 固定到引导臂的印刷电路和用于使所述引导臂和所述印刷电路的热膨胀系数至少在头臂的寻找方向上彼此基本相等的偏转补偿构件。 在这种头臂上不发生面外方向的热变形,而不管安装有磁盘驱动器的环境的温度如何变化。 头臂还可以包括引导臂和由吸湿材料形成的印刷电路,并在其全部或部分表面上覆盖由不透湿水分的防潮材料形成的覆盖层。 在这种头臂上不发生面外方向的变形,而不管安装有磁盘驱动器的环境的湿度是否变化。 因此,可以使偏离轨迹的发生的可能性最小化。

    • This disclosure relates to a small boat construction such as a recreational water scooter type. The boat includes a hull, a control handle, and a pivot connecting the handle to the hull, the pivot enabling the handle to be pivoted between a lowered position, an upright position and intermediate positions. The boat further includes a mechanism connected between the handle and the hull adjacent the pivot, the mechanism including a resistance mechanism effective for resisting movement of the handle to the upright position, and apparatus for canceling the resistance mechanism.
    • 本公开涉及一种小型船舶结构,例如休闲水上踏板车型。 船包括船体,控制手柄和将手柄连接到船体的枢轴,使得手柄能够在下降位置,直立位置和中间位置之间枢转。 所述船还包括连接在所述手柄和所述船体之间的机构,所述机构包括抵抗所述手柄到所述直立位置的运动的阻力机构,以及抵消所述阻力机构的装置。
