    • A method of stamping a part from an elongated strip of multi-layered material. The multi-layered material includes a viscoelastic intermediate layer, and upper and lower layers that are relatively rigid with respect to the intermediate layer. The method includes providing symmetrically aligned top and bottom punches each including a material displacement edge corresponding with a desired shape of the part. Each of the material displacement edges are defined by a rake surface and a part interface surface that combine to form a positive rake angle. The strip is positioned between the top and bottom punches. The top and bottom punches then shear a portion of the upper and lower layers, respectively. More particularly, symmetrical groove patterns are formed in the upper and lower layers, defining a perimeter of the part. The part is then removed from the strip along the perimeter.
    • 一种从细长的多层材料条冲压零件的方法。 多层材料包括粘弹性中间层以及相对于中间层相对刚性的上层和下层。 该方法包括提供对称排列的顶部和底部冲头,其各自包括对应于部件的期望形状的材料位移边缘。 每个材料位移边缘由组合以形成正前角的前倾表面和部件界面表面限定。 带材位于顶部和底部冲头之间。 顶部和底部冲头分别剪切上部和下部的一部分。 更具体地,在上层和下层中形成对称的凹槽图案,限定了该部分的周边。 然后将该部分沿着周边从条带上移除。

    • A programmable memory interface circuit includes a programmable DLL delay chain, a phase offset control circuit and a programmable DQS delay chain. The DLL delay chain uses a set of serially connected delay cells, a programmable switch, a phase detector and a digital counter to generate a coarse phase shift control setting. The coarse phase shift control setting is then used to pre-compute a static residual phase shift control setting or generate a dynamic residual phase shift control setting, one of which is chosen by the phase offset control circuit to be added to or subtracted from the coarse phase shift control setting to generate a fine phase shift control setting. The coarse and fine phase shift control settings work in concert to generate a phase-delayed DQS signal that is center-aligned to its associated DQ signals.
    • 可编程存储器接口电路包括可编程DLL延迟链,相位偏移控制电路和可编程DQS延迟链。 DLL延迟链使用一组串行连接的延迟单元,可编程开关,相位检测器和数字计数器来产生粗略的相移控制设置。 然后,粗略的相移控制设置用于预先计算静态残留相移控制设置或生成动态残留相移控制设置,其中一个由相位偏移控制电路选择以被加到或从粗略 相移控制设置,以产生精细的相移控制设置。 粗调和精细相移控制设置一致地产生相位延迟的DQS信号,其中心对准其相关联的DQ信号。

    • A circular parachute includes a circularly shaped canopy having a skirt band and a plurality of cascaded, Y-shaped main suspension lines connected to the skirt band that converge downwardly to a suspension line junction. Each main suspension line includes a lower segment that branches into at least two upper segments. One embodiment includes a canopy with a vent band and Y-shaped vent suspension lines that converge downwardly to a vent centerline. A generally planar reefing device for slowing the opening of the canopy defines a plurality of openings through which the main suspension lines extend. In one reefing device embodiment, a strip of material (e.g., a nylon strap) is folded into multiple strip segments arranged in a five-point star configuration. Eyelets in the form of brass grommets extending through the strip segment junctions form suspension-line-receiving openings.
    • 圆形降落伞包括圆形顶篷,其具有裙带和连接到裙带的多个级联的Y形主悬挂线,其向下收敛到悬挂线路连接处。 每个主悬挂线包括分成至少两个上段的下段。 一个实施例包括具有通气带的顶篷和向下收敛到排气中心线的Y形通风悬浮线。 用于减缓顶盖开口的大体上平面的折叠装置限定了多个开口,主悬挂线通过该开口延伸。 在一个折叠装置的实施例中,材料条(例如,尼龙带)被折叠成以五点星形配置布置的多个条段。 穿过条带段结的黄铜索环形式的孔眼形成悬挂线接收孔。
