Title: Manufacture of cation resin
Inventor: MARUKO UIZUMAA
IPC: C25D13/06
Filed: 1982-09-09
Abstract: An improved process for the preparation of cationic resins derived from polyepoxides is disclosed. Typically, the process comprises contacting the polyepoxide with particular polyether polyols and heating the two together to form a resin which may then be reacted with a cationic base group former such as an amine and acid. Aqueous dispersions of the cationic resins prepared by the improved process are useful for coating applications, particularly cationic electrodeposition. They exhibit good low temperature cure response and the cured coatings have good physical properties such as resistance to water, detergent and salt spray corrosion.

Abstract: PURPOSE:To widen the width of stripes enabling fundamental lateral-mode oscillation by burying an active layer, a lower surface thereof is flat and the surface thereof is convex, into a groove. CONSTITUTION:Current stopping layers 2, 3, which have different conduction types and consist of upper and lower two layers, are formed onto a substrate 1 composed of a compound semiconductor. A clad layer 5, the surface thereof is approximately flat, is buried into the groove reaching the substrate 1 from the layers 2, 3. The active layer 6, the surface thereof is convex, is shaped onto the layer 5. A clad layer 7 is formed onto the layer 6. Consequently, there is a flat section C at the inner center of the layer 6, the scattering loss of beams is small in the flat section, and loss is large under the influence of the unevenness of the groove at the outside of the flat section C. Accordingly, the difference of the scattering loss of a fundamental mode and a higher mode is large, and stable fundamental-mode oscillation is kept even in case of high optical output.

The other side of the film is sulfonated so that a cation exchange group is introduced. The covering layer is separated and an anion exchange group is introduced into the released surface. Polypropylene, etc., capable of not being corroded by a sulfonating liquid, may be used as the covering layer. Sulfonating reaction, done by sulfuric acid, etc., forms a layer made of sulfonic group to a thickness of 1/10-9/10 of the cross-sectional area of the film on the one side of the film. The introduction of the anion exchange group can be carried out by any conventional method.
