    • Layer processing to grow a layer structure upon a substrate surface comprises supplying a vapor mixture stream to the substrate (28) to deposit constituents, monitoring growth with an ellipsometer (12) and using its output in real-time growth control of successive pseudo-layers. A Bayesian algorithm is used to predict a probability density function for pseudo-layer growth parameters from initial surface composition, growth conditions and associated growth probabilities therewith, the function comprising discrete samples. Weights are assigned to the samples representing occurrence likelihoods based on most recent sensor output. A subset of the samples is chosen with selection likelihood weighted in favor of samples with greater weights. The subset provides a subsequent predicted probability density function and associated pseudo-layer growth parameters for growth control, and becomes a predicted probability density function for a further iteration of pseudo-layer growth.
    • 在衬底表面上生长层结构的层处理包括将蒸汽混合物流供应到衬底(28)以沉积成分,利用椭偏仪监测生长(12),并使用其输出实现连续伪层的实时生长控制 。 贝叶斯算法用于预测来自初始表面组成,生长条件及其相关生长概率的伪层生长参数的概率密度函数,该函数包括离散样本。 根据最近的传感器输出,将重量分配给表示出现可能性的样本。 选择样本的子集,其中选择可能性加权,有利于具有更大权重的样本。 该子集提供用于生长控制的随后的预测概率密度函数和相关联的伪层生长参数,并且成为进一步迭代伪层生长的预测概率密度函数。

    • The weaving tool is provided with a pair of pivotally mounted elements and a spring for biasing the elements together. The forward portion of the tool is made with a thin tapered portion and the material engaging portions mate with each other to form a continuation of the forward portion. The forward portion of the tool may pass through a mesh backing without significantly enlarging the holes of the backing. The tool is positioned in the backing so that upon opening, the holes in the backing are not enlarged. Strips of material can be pulled back through the openings when the tool is removed.
    • 编织工具设置有一对枢转安装的元件和用于将元件偏置在一起的弹簧。 工具的前部由薄的锥形部分制成,并且材料接合部分彼此配合以形成前部的延续部。 工具的前部可以穿过网状背衬而不会明显地增大背衬的孔。 该工具定位在背衬中,使得在打开时,背衬中的孔不被扩大。 当工具取出时,材料条可以通过开口拉回。
