  • Micro-optic adhesive assembly and method therefor
    Patent number: 6684014
    Abstract: The invention relates to a micro-optic adhesive assembly and a method for making a micro-optic assembly. The method of joining optical assemblies in accordance with the present invention improves the strength and shock resistance of adhesive joints in micro-optic devices without affecting the optical path. The adhesive assembly of the present invention has sufficiently flexibility to be able to conform to different alignment geometries without introducing significant bulk or thermal expansion incompatibility. Further the improved method is compatible with the device manufacturing techniques and does not add significant manufacturing complexity.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: January 27, 2004
    Assignee: JDS Uniphase Corporation
    Inventors: Li Wu, Jiwu Ling, Weimin Chen, Chenggang Xin, Zhen Miao, Cuilian Zhan

  • Simulated moving bed absorption separation process
    Patent number: 5884777
    Abstract: Disclosed is a method for the adsorptive separation by utilizing an improved simulated moving bed. This invention provides an improved formula for the calculation of primary flush flowrate by correspondingly associating the primary flush flowrate with each connection line by introducting a volume factor and carring out sequential control so as to reduce the amount of the flush stream and increase product purity and yield.
