    • A compact laser programmable fuse structure has a central line and two sets of fuses extending from opposite sides of the central line. An opening through a passivation layer exposes the fuses and overlies the central line. In one embodiment, the opening also exposes the portions of the central line. The central line is made of fuse material or another material for which the opening does not create reliability problems. In one embodiment of the invention, the central line and the fuses are parts of a single contiguous region of polysilicon. This fuse structure has a length that is about half the length of conventional fuse structure having the same number of fuses because two fuses, one on either side of the central line, fit within a length used for a single fuse in conventional fuse structures.
    • 紧凑的激光可编程熔丝结构具有中心线和两组从中心线的相对侧延伸的保险丝。 通过钝化层的开口露出熔丝并覆盖中心线。 在一个实施例中,开口也暴露中心线的部分。 中心线由保险丝材料或其他材料制成,开口不会产生可靠性问题。 在本发明的一个实施例中,中心线和熔丝是多晶硅的单个连续区域的部分。 这种熔丝结构的长度大约是具有相同数量的保险丝的常规熔断器结构的长度的一半,因为两个保险丝(一个位于中心线的任一侧上)都配合在常规保险丝结构中用于单个保险丝的长度内。

    • A trocar containing a universal seal for sealing against surgical instruments of varying diameter to maintain insufflation in the body cavity is disclosed. The universal seal has an elastomeric sealing component with a centrally located interior region containing an aperture, and a concentrically located sealing region. The sealing region is composed of an integral laminate having an overlaying layer co-molded with an underlying layer. The overlaying layer has a hardness between about 40 Shore A Durometer Scale and about 80 Shore D Durometer Scale. The underlying layer has a hardness between about 5 Shore A Durometer Scale and about 40 Shore A Durometer Scale. The co-molded laminate balances the properties of tear resistance and elasticity which are necessary for a working universal seal, and does so without the need for resilient legs or protectors to facilitate the opening of the aperture of the seal or to prevent tearing when instruments are inserted.
    • 公开了一种套管针,其包含用于密封不同直径的外科器械的通用密封件,以维持体腔内的吹气。 通用密封件具有弹性体密封部件,其具有位于中心的内部区域,该内部区域包含孔和同心位置的密封区域。 密封区域由具有与下层共同模制的覆盖层的整体层压体组成。 覆盖层具有在约40肖氏硬度计量度和约80肖氏硬度计量度之间的硬度。 下层具有在约5肖氏硬度计量度和约40肖氏硬度计量度之间的硬度。 共同成型的层压板平衡了工作通用密封件所必需的抗撕裂性和弹性的性质,并且不需要弹性腿或保护件来促进密封件的孔的打开,或者当仪器是 插入。
