    • A method of fabricating a current control device is presented. The method impregnates a pressure conduction composite within a current control device with a fluid additive via suffusion. The suffusion process is performed by placing the pressure conduction composite within a bath of a liquid additive. The method generally includes the steps of mixing a compressible non-conductive matrix and conductive filler, forming a pressure conduction composite composed of the non-conductive matrix having the conductive filler electrically isolated therein, suffusing the composite within a bath so as to impregnate the composite with an additive, and attaching a pair of conductive plates to the composite. Alternate methods include attaching non-conductive plates to the composite, forming pores within the pressure conduction composite, and inserting a temperature responsive material into a porous composite.
    • 提出了一种制造电流控制装置的方法。 该方法通过充满浸渍流体添加剂的电流控制装置内的压力传导复合材料。 通过将压力传导复合材料放置在液体添加剂的浴中来进行填充过程。 该方法通常包括混合可压缩非导电基质和导电填料的步骤,形成由非导电基体组成的压电传导复合材料,该非导电基体具有电隔离的导电填料,使得该复合物在浴液中浸渍, 并添加一对导电板到复合材料。 替代方法包括将非导电板附接到复合材料,在压力传导复合材料内形成孔,并将温度响应材料插入多孔复合材料。

    • A head positioner is described wherein a read/write head is slidably propelled along an arm by an electrically, an acoustically, or an magnetically active material. One embodiment is comprised of a driver arm with a single slidable positioner. The driver arm is composed of a rail with two driver layers. An isolator layer between rail and each driver layer prevents distortion of rail when driver layers are activated. A wear-resistant, low-friction layer prevents damage to driver layer and facilitates sliding motion between positioner and driver arm. Positioner is propelled along driver arm by energizing driver layer composed of either a piezoelectric, piezoceramic, electrostatic, electromagnetic, or electrostatic material. At least one read/write head is attached to the positioner for data communication purposes with a storage element. In an alternate embodiment, two positioners are separately and independently slidable along a single driver arm.
    • 描述了头部定位器,其中读/写头通过电,声学或磁性活性材料沿着臂可滑动地推进。 一个实施例由具有单个可滑动定位器的驱动臂构成。 驱动臂由具有两个驱动层的轨道组成。 轨道和每个驱动器层之间的隔离层可以防止驱动层激活时轨道发生变形。 耐磨低摩擦层可防止驱动层受损,并有助于定位器与驱动臂之间的滑动。 通过激励由压电,压电陶瓷,静电,电磁或静电材料组成的驱动层,定位器沿着驱动臂推进。 至少一个读/写头连接到定位器,用于与存储元件的数据通信目的。 在替代实施例中,两个定位器可以沿着单个驱动臂单独且独立地滑动。
