Inventor: ONO SHIGEKI
IPC: G01N30/88
Filed: 1990-01-12
Abstract: PURPOSE:To efficiently and accurately measure the MW distribution of polysulfone by dissolving polysulfone in dimethylformamide (DMF) under heating and subjecting the same to gel permeation chromatography (GPC) using DMF as an eluent to detect polysulfone by an ultraviolet spectrophotometer. CONSTITUTION:A solution prepared by dissolving a sample to be analyzed in a (mobile phase) solvent is supplied to the column 4, for example, packed with fine globular particles of a porous styrene/divinylbenzene copolymer of GPC to separate the sample by a molecular size in the order of large sample molecules to analyze the amounts of sample molecules. DMF is used as the dissolving liquid of the polysulfone sample and DMF is used as the mobile phase of the GPC. In this case, an ultraviolet spectrophotometer 6 is used as the detector of the GPC. By this method, the MW distribution of polysulfone can be measured efficiently and accurately.

Title: Insulating ultrathin membrane
Inventor: KAMIKITA MASAKAZU
IPC: B01J19/00
Filed: 1988-01-13
Abstract: PURPOSE:To form an insulating ultrathin membrane with a good insulating property upon a conductor whose surface is not covered with a practically insulating oxide, by laminating a conductor with a specific composition and an insulating ultrathin membrane alternately in layers upon an insulating substrate. CONSTITUTION:A specific conductor 2 and an insulating ultrathin membrane 1 are laminated alternately in layers upon a substrate 3. The conductor 2 is formed by etching Au and Ag, and Cr or a transparent conductor ITO on the substrate 3, and has no practically insulating oxide upon its surface. In addition, the thin membrane 1 is formed as a result of lamination of a 10-500Angstrom  thick metallic oxide membrane and a Langmuir project membrane in this order using Langmuir project technique in order that it may cover at least a part of the surface of the conductor 2. It should be added that the metallic oxide membrane is similar to silicon oxide membrane and produced with sputtering technique. Further, the Langmuir project membrane has a cyclic structure resulting from accumulation of polymers. Utilizing the thin membrane 1 produced as above, the ultrathin membrane 1 is obtained that has also a good insulating property when applied to the above structure.
