    • A semiconductor substrate for a micro-fluid ejection device. The substrate includes plurality of micro-fluid ejection actuators disposed adjacent a fluid supply slot in the semiconductor substrate. A plurality of power transistors, occupying a power transistor active area of the substrate, are disposed adjacent the ejection actuators and are connected through a first metal conductor layer to the ejection actuators. An array of logic circuits, occupying a logic circuit area of the substrate, is disposed adjacent the plurality of power transistors and is connected through a polysilicon conductor layer to the power transistors. A power conductor and a ground conductor for the ejection actuators is routed in a second metal conductor layer. The power conductor overlaps at least a portion of the power transistor active area of the substrate and the ground conductor overlaps at least a portion of the logic circuit area of the substrate.
    • 一种用于微流体喷射装置的半导体衬底。 衬底包括邻近半导体衬底中的流体供应槽设置的多个微流体喷射致动器。 占据基板的功率晶体管有源区的多个功率晶体管被设置在喷射致动器附近,并且通过第一金属导体层连接到喷射致动器。 占据基板的逻辑电路区域的逻辑电路阵列被布置成与多个功率晶体管相邻,并且通过多晶硅导体层连接到功率晶体管。 用于喷射致动器的电源导体和接地导体在第二金属导体层中布线。 电源导体与衬底的功率晶体管有源区域的至少一部分重叠,并且接地导体与衬底的逻辑电路区域的至少一部分重叠。

    • A guardrail support, attachment and positioning block used to space guardrails from support posts is disclosed. The positioning or spacer block is a generally rectangular block having corded-out cavities to reduce weight and tabs or projections for cooperatively engaging the sides and top of a support post as well as the edges of the guardrail during roadway safety barrier system installation. Webbing within one or more of the cavities may be used for additional structural support. To optimize the strength to weight characteristics of the spacer block, the spacer block may be formed by low-pressure injection molding. The spacer block may also be formed from virgin and/or recycled plastic material and/or include virgin or recycled rubber material, such as that obtained from the regrind of used tires, and/or another elastomeric materials from other sources.
    • 公开了一种用于将护栏用于支撑柱的护栏支撑,附接和定位块。 定位或间隔块是一个大致矩形的块体,具有用于减轻重量的带有线的空腔并且用于在道路安全屏障系统安装期间配合地接合支撑柱的侧面和顶部以及护栏的边缘。 在一个或多个空腔内的织带可以用于附加的结构支撑。 为了优化间隔块的强度与重量特性,可以通过低压注射成型形成间隔块。 间隔块也可以由未加工的和/或再循环的塑料材料形成,和/或包括原始或再循环的橡胶材料,例如从旧轮胎的再研磨得到的橡胶材料和/或来自其他来源的其它弹性体材料。
