    • A magnetic disk drive includes a magnetic recording medium and a magnetic head slider adapted to fly over a surface of a magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its periphery. The vibration suppressing groove quickly damps out translational and pitching vibrations in the flying height direction of the magnetic head slider while stabilizing its flying.
    • 磁盘驱动器包括磁记录介质和适于在磁记录介质的表面上飞越并读取或写入信息的磁头滑块。 磁头滑块包括滑块空气支承表面和磁换能器。 滑块空气轴承表面包括具有前导轨表面和前阶梯支承表面的前垫,具有后轨表面和后台阶支承表面的后垫,以及插入在前垫和后垫之间的负压槽。 在后轨面上形成振动抑制槽,使其比后轨面更深,并在其周边封闭。 振动抑制槽在稳定其飞行的同时快速地减小磁头滑块的飞行高度方向上的平移和俯仰振动。

    • The object of the present invention resides in providing a method and instrument of polymer processing treatment, wherein a sudden pressure change due to expansion by gasification of a reactant when it is exhausted from a reacting extruder is given in a little amount to a molding machine for a treated substance, and a change in the amount of the material supplied to the molding machine and a variation in molding are little, and hence continuous and uniform molding is possible. That is, the method of the present invention resides in a method of polymer processing treatment, which includes the steps of: reacting a polymer with a reactant under mixing and stirring at a high temperature and a high pressure in the inside of a reacting extruder to produce the treated substance; introducing said treated substance and a remaining reactant into a reactant-separation tank to separate the treated substance and the reactant; and molding the separated treated substance.
    • 本发明的目的在于提供一种聚合物加工处理的方法和仪器,其中当反应物从反应挤出机排出时,由反应物的气化引起的膨胀引起的突然的压力变化少量给予成型机 被处理物质和供给到成型机的材料量的变化和成型变化很小,因此可以连续均匀地成型。 也就是说,本发明的方法在于聚合物加工处理方法,其包括以下步骤:在反应挤出机内部的高温和高压下在混合和搅拌下使聚合物与反应物反应, 生产经处理的物质; 将所述处理的物质和剩余的反应物引入反应物分离罐中以分离处理的物质和反应物; 并模制分离的处理物质。
