Multi‐layered flat‐surface micro‐optical components directly molded on an LCD panel

Abstract— We have developed a process to fabricate optical components, such as a lens, prism, or diffuser, directly on to a glass substrate. Processes include precision mastering by diamond cutting and multi‐layer photopolymer (2P) molding to realize flat surfaces and the integration of multiple components with an alignment within a few micrometers.

MODELING LIQUID MASS TRANSFER IN HIGEE SEPARATION PROCESS

Correspondence concerning this paper should be addressed to Professor Richard S.H. Mah. Hsien-Hsin Tung is now affiliated with Department of Chemical Engineering, California Institute of Technology

Penetration theory is used to describe the liquid mass transfer in Higee separation process. Within a possible range of effective areas, it is shown that the predicted mass transfer coefficients are in reasonable agreement with the estimated mass transfer coefficients. The estimated coefficients were calculated from the experimental data and the possible effective areas. Hence it is concluded the penetration theory is generally applicable to describe liquid mass transfer in Higee separation process. The comparison also suggests that liquid mixing at the junctions of packing materials may be more complete in Higee process than in traditional process.

蜡晶改进剂对润滑油馏分中蜡组分结晶控制作用的研究

抚顺石油一厂通过大量试验和溶剂脱蜡装置的连续生产证明:加工减二线,套管易上压,滤机上蜡饼泡松易堆蜡,应选用合适的改进剂以控制蜡晶生成树枝状;减四、五线重馏分蜡晶细密,套管不易上压,滤机易失效,应选用和适当加入合适的改进剂以增大聚集状晶体粒度;减三线蜡晶粒度大,为套管上压周期较长,滤机上蜡饼通透性好,滤速快,可根据需要决定是否使用改进剂。提出了针对不同润滑油馏分中不同蜡晶型选用合适的蜡晶改进剂可以相应解决不同馏分的生产难点,提高处理能力,改善产品质量。
