    • An inventive brush and scrubbing device is provided for simultaneously scrubbing both planar and profiled (e.g., edge) surfaces of a thin disk such as a semiconductor wafer. The inventive brush has a contact surface having two portions, a planar portion for contacting a planar surface of a wafer, and a profiled portion for contacting an edge surface of a wafer. The profile of the profiled portion preferably follows the edge profile of a wafer to be cleaned by the brush. The profiled portion may have a higher modulus of elasticity than does the planar portion. Preferably the brushes are roller type PVA brushes having a plurality of nodules formed thereon.
    • 提供了一种创新的刷子和擦洗装置,用于同时擦洗诸如半导体晶片的薄盘的平面和成型(例如,边缘)表面。 本发明的刷具有具有两个部分的接触表面,用于接触晶片的平面的平面部分和用于接触晶片的边缘表​​面的成型部分。 成形部分的轮廓优选地遵循待刷清洁的晶片的边缘轮廓。 成型部分可以具有比平坦部分更高的弹性模量。 优选地,刷子是在其上形成有多个结节的辊式PVA刷。

    • A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.
    • 公开了一种包括多个间隔开的带状元件和相交连接件的可径向扩张的支架。 带状元件具有大致蛇形结构,以向每个带状元件提供大致正弦曲线的连续波。 波的特征在于沿着圆柱体大致纵向方向的多个峰和谷,使得当支架从第一直径扩展到第二直径时,带状元件中的波浪打开。 交叉连接件基本上为U形并终止在第一和第二柄部中。 链节的第一柄从带状元件上的峰和谷之间的区域发出,并且链节的第二柄从相邻带状元件上的峰和谷之间的区域发出。

    • In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector columns. Each serpentine band comprises a plurality of alternating straight band struts and turns. Adjacent serpentine bands are connected across a connector column by a plurality of connector struts. Each connector strut is connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band. The turns of a serpentine band comprise connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut. At least one serpentine band comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. At least one serpentine band comprises a repeating pattern of three band struts and then one band strut extending between connected turns as the serpentine band is traversed.
    • 在至少一个实施例中,支架包括多个蛇形带和多个连接柱。 每个蛇形带包括多个交替的直带支柱和匝。 相邻的蛇形带通过多个连接器支柱连接在连接器列上。 每个连接器支柱的一端连接到一个蛇形带的转弯处,另一端连接到另一个蛇形带的转弯处。 蛇形带的转弯包括连接到连接器支柱的连接匝和不连接到连接器支柱的未连接匝。 至少一个蛇形带包括三个带状支柱的重复图案,然后在穿过蛇形带时在连接的匝之间延伸五个带状支柱。 至少一个蛇形带包括三个带状支柱的重复图案,然后在穿过蛇形带时在连接的匝之间延伸一个带支柱。
