简介：在连续热剧降的电镀的过程控制锌的电影厚度，它从早天被知道通过一把空气刀的煤气的擦去是最有效的。擦在电镀使用过程的气体引起为涂层的某个高速度从长带边打起浪花的一个问题。在现在的学习，喷气结构和在板表面侵犯压力的分发上的Coanda嘴的偏转角度的效果因此数字地并且试验性地被调查。在数字分析，管理方程由三维的时间组成了依赖完整的海军司烧方程，标准k-吗？等等解决狂暴的应力的骚乱模型被雇用。在实验，16隧道压力扫描阀门和3轴汽车穿越单位被用来在长带表面测量侵犯的压力。作为结果，它被发现那为空气刀的一样的嘴裂缝的偏转角度越小，侵犯的压力是越多larger。减少分离水泡的尺寸并且提高切的能力，与Coanda嘴使用一把空气刀是明智的。

简介：一个新奇帮助多晶硅的控制硅的整流器(SCR)被介绍；在这篇论文分析了，它在HHNEC的0.18μm电可擦可编程只读存储器过程被制作。帮助多晶硅的SCR利用多晶硅层没有占据额外的布局区域，由通行证帮助静电的分泌物(ESD)电流。TLP当前电压(I-V)测量结果显示出给一样的布局区域那，帮助多晶硅的SCR的坚韧性性能能被改进到3次常规MLSCR的。而且，一个手指如此的帮助多晶硅的SCR，占据仅仅947μm，2]布局区域，能经历7-kVHBMESD应力。结果进一步证明帮助多晶硅的SCR的S类型I-V特征对由改变设备尺寸的不同操作条件可调节。与传统的SCR相比，这新SCR能绕过更多的ESD水流；消费更小的IC区域。
