Filed: 1990-11-14
Abstract: PURPOSE:To further unify the flow of a bromine complex for the whole area of a positive electrode plate by connecting a complex feed path feeding the bromine complex stored in a positive electrode liquid storage tank to a positive electrode side reaction tank to the inner position of the reaction tank.

Filed: 1990-11-15
Abstract: PURPOSE:To obtain a substance containing dissolved chitosan for use as food or a food material which can be easily mixed with other general foods and is amenable to oral ingestion by adding chitosan to kojic acid and keeping the obtained mixture below a specified temperature. CONSTITUTION:Chitosan is added to kojic acid, and the resulting mixture is kept at about 30 deg.C or below to dissolve the chitosan. It is desirable from the viewpoints of increasing the solubility of chitosan and of making the chitosan nonastringent that the kojic acid to be used is red kojic acid prepared by fermenting red koji. It is more desirable from the same viewpoints that a red kojic acid mixture containing natural mineral spring water, hibiscus extract and ethanol is used as the above kojic acid. When the dissolution temperature is above about 30 deg.C, the dissolved chitosan is fermented and gradually emits a foreign odor undesirably. The obtained substance containing the dissolved chitosan is nonastringent.
