    摘要： A method and apparatus for thermoforming 3-dimensional articles of chosen wall thickness dimensions from a polar polymer sheet. The polymer sheet is dielectrically heated, the heating being controlled to impress a predetermined thermal pattern on the sheet. The thermal pattern is selected in accordance with the amount of stretching to which each area of the sheet is subjected during the subsequent work-forming step, the areas subjected to greater stretching being heated to a lower temperature and vice versa. Thus, the stretching action is balanced and results in accurate control of the wall thickness of the final article.

    摘要翻译： 一种用于从极性聚合物片材热成型选择的壁厚尺寸的三维制品的方法和装置。 聚合物薄片被介电加热，加热被控制以在片材上施加预定的热图案。 根据在随后的加工成型步骤期间片材的每个区域经受的拉伸量来选择热图案，将经受较大拉伸的区域加热到较低温度，反之亦然。 因此，拉伸作用是平衡的并且导致最终制品的壁厚的精确控制。

    摘要： Apparatus for performing a plasma enhanced chemical vapor deposition on an edge of a polycarbonate sheet includes a conduit having an axially disposed slit therethrough for engaging the sheet so as to position the edge in the conduit. Axially disposed electrodes are attached to the conduit and positioned to be on generally opposite sides of the edge. Means are provided for applying a separate electrical potential to each of the electrodes, and at least one aperture is provided in the conduit for introducing and removing a gas therefrom.
