    • The present invention relates to an electric valve capable of producing podic mass-flow modulation of a gaseous, liquid, or mixed-phase medium over wide ranges of frequencies, pressure, and flow rates. Such mass-flow modulation can be used to periodically shed large-scale vortices at the outlet and to manipulate their dynamics allowing the user to actively control fluid mixing and transport further downstream. The device has a piezoelectric wafer that in a relaxed state abuts the upstream end of the outlet tube separating the pressurized fluid in the plenum with the outlet. The device has an apparatus for applying electric field to the wafer, which distorts the wafer and ruptures the seal forming a throat area that controls the fluid mass flux. Due to the fast response of the piezoelectric material to an electric field, the throat area can be modulated rapidly in time making the device operable even at high frequencies. The present invention is particularly useful for actively controlling fuel-air mixing in a combustor. However, it may be utilized in other applications such as in medical drug administration for inhalation therapy.
    • 本发明涉及一种能够在宽范围的频率,压力和流速下对气态,液体或混合相介质进行周期性质量流量调制的电动阀。 这种质量流量调制可用于周期性地在出口处流出大尺度的涡流并操纵其动力学,从而允许使用者主动地控制下游的流体混合和输送。 该装置具有处于松弛状态的压电晶片,该压电晶片与出口管的上游端相邻,以将出气口中的加压流体分开。 该装置具有向晶片施加电场的装置,其使晶片扭曲并破裂形成控制流体质量通量的喉部区域的密封。 由于压电材料对电场的快速响应,喉部区域可以在时间上快速调制,使得器件即使在高频也可操作。 本发明对于主动地控制燃烧器中的燃料 - 空气混合特别有用。 然而,它可以用于其它应用,例如用于吸入治疗的药物治疗。

    • A method and apparatus is disclosed for texturizing magnetic storage disks. The disk texturizing apparatus utilizes a combination of servomotors for rotating the disk and oscillating the disk towards and away from a texturizing media. The servomotors are controlled by a closed-loop control system which monitors and synchronizes the angular and linear position of the disk. Through such control, the disk rotation speed may be modulated in conjunction with the linear oscillation, thereby allowing a higher degree of triangularity in the texturization pattern. A pattern generation system and a graphical user interface for specifying, modeling, generating, modifying and displaying disk texturizing patterns are also disclosed. The texturizing pattern may be displayed in polar plot and linear plot form so that the user can more easily visualize and design the texturizing pattern. Warning signals are used when the texturizing pattern exceeds the acceleration or amplitude limitations of the physical texturizing apparatus, or when the designed pattern repeats. The pattern generation system may also be used to generate a data sequence describing a particular pattern which is exportable to the physical disk texturizing apparatus.
