    摘要: The present invention relates to a process for preparing the controlled-release chitosan microcapsule, more specifically to a process for preparing the sustained-release chitosan microcapsule capable of releasing at an appropriate rate for a long time, which is characterized by: a) Biodegradable chitosan polymer is used for the capsule material; b) The capsule is kept stable during the release time by the rapid and effective crosslinking reaction between the chitosan polymer and the double crosslinking agent on the surface of tiny particles formed by a new emulsion interface reaction method using a double crosslinking agent of sulfuric acid and glutaraldehyde; and c) The microcapsule which is smaller than several &mgr;m s can be easily formed and the capsule is kept stable for a long release time because an insoluble polymer film whose source material is biodegradable is formed after the release.

    摘要: This invention relates to a polyion complex separation membrane with a double structure, which is applicable in the separation process of a water-soluble mixture having ionic molecules or particles by means of reverse osmotic pressure for the purposes of recovering expensive ionic organic materials such as anionic emulsifiers from the waste water. More particularly, this invention relates to said membrane having anionic polymers, as substrate, which is immersed into a cationic polymer solution containing a multivalent ion cross-linking agent, by which a cross-linkage within the internal of the separation membrane is achieved, thereby forming an ion complex between ionic polymers of opposite ion at the surface of the separation membrane to yield a stable separation membrane of a double structure.

    摘要: In a method of erasing a nonvolatile memory device, an erase operation is performed on memory cells of a selected block. A first soft program operation is performed on the cells on which the erase operation has been performed. The erase operation and the first soft program operation are repeatedly performed by increasing an erase voltage by a first step voltage until a threshold voltage of the memory cells becomes lower than a first erase verify voltage. When the threshold voltage of the memory cells becomes lower than the first erase verify voltage, a second soft program operation is performed. The second soft program operation is repeatedly performed by increasing a soft program voltage by a second step voltage until a cell is programmed to have a soft program verify voltage.
