    • PROBLEM TO BE SOLVED: To provide a device capable of individually testing each layer of thin membrane of an integral multi-layered device. SOLUTION: This device can perform a continuous (or serial) filter via two or more filtering layers for obtaining a desired characteristics of preserving ratio or the like, and test the integrity of respective layers separately, and has two or more separate filtering layers. Each of them is formed of two or more filtering regions containing one each filter layer 2 and 20. Each region has one each filter layer 2, 20, and a first end cap 6 connected to a first end part of the filter, and a second end cap 10 connected to a second end part of the filter. These regions are disposed concentrically in such a manner that a first region is disposed inside a second region, and the second region is disposed inside a third region. Each region is separately formed, and integrity test is performed separately before a final assembly. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供能够单独测试整个多层装置的每个薄膜层的装置。 解决方案:该装置可以通过两个或更多个滤波层执行连续(或串联)滤波,以获得所需的保持比等特性,并分别测试各层的完整性,并具有两个或多个分离滤波 层。 它们中的每一个由包含一个每个过滤层2和20的两个或更多个过滤区域形成。每个区域具有一个每个过滤层2,20和连接到过滤器的第一端部的第一端盖6, 端帽10连接到过滤器的第二端部。 这些区域以这样的方式同心地设置,使得第一区域设置在第二区域内,并且第二区域设置在第三区域内。 每个区域分开形成,在最终组装之前单独执行完整性测试。 版权所有(C)2007,JPO&INPIT
