    • A write amplifier circuit in a magnetic storage system has a cross coupling circuit and an active damp circuit to supply an improved write current to the head writing the data onto the media within the magnetic storage system. The inclusion of the cross coupling circuit decreases a rise time and a fall time associated with the write current. The active damp circuit reduces the undershoot and ringing of the write current. Thus, the write amplifier circuit is suitable for high speed data storage writing applications requiring minimal distortion of the data written to a magnetic medium. The write amplifier circuit achieves these improvements in the waveform of the write current by incorporating circuit elements and using both a negative feedback path and a feedforward path. In particular, the cross coupling circuit provides a feedforward path within the write amplifier circuit to a first current which creates a second current that is proportional and greater than the first current such that the second current increases the write current available for the head. Similarly, the active damp circuit provides a negative feedback path from the output terminals of the write amplifier circuit to a third current which creates a fourth current that is proportional and greater than the third current such that the fourth current damps an undershoot and ringing associated with the write current.
    • 磁存储系统中的写放大器电路具有交叉耦合电路和有源阻尼电路,用于向磁头提供改善的写入电流,从而将数据写入到磁存储系统内的介质上。 交叉耦合电路的包含减少了与写入电流相关联的上升时间和下降时间。 有源潮湿电路可以减少写入电流的下冲和振荡。 因此,写放大器电路适用于要求写入磁介质的数据失真最小的高速数据存储写入应用。 写放大器电路通过并入电路元件并使用负反馈路径和前馈路径来实现写入电流波形的这些改进。 特别地,交叉耦合电路将写入放大器电路内的前馈路径提供到第一电流,该第一电流产生比第一电流成比例并且大于第一电流的第二电流,使得第二电流增加可用于磁头的写入电流。 类似地,有源阻尼电路提供从写入放大器电路的输出端子到第三电流的负反馈路径,该第三电流产生比第三电流成比例并且大于第三电流的第四电流,使得第四电流抑制下行和与 写入电流。

    • A chair is provided which includes an inner member for supporting the body of a person and an outer member for supporting the right and left edges of the inner member. The inner member is made of a synthetic resin and formed into a plate so that the inner member is elastically deformed under the weight of the person. The inner member is attached to the outer member with its side portions supported. Thus, behind the inner member is a space for allowing the inner member to be deformed. In order to be applied to the seat of a chair, preferably, the outer member includes a metal base and a pair of auxiliary supporting elements to be fitted on the metal base. The inner member and the auxiliary supporting elements are fixed to each other in a non-releasable manner by an engaging assembly including engagement nails and engagement holes.
