Patent JP-H05271302-A (JP)
Title: Production of chitin or chitosan from carapace of crustacea
IPC: C08B37/08
Filed: 1992-03-26
Abstract: PURPOSE:To safely produce chitin by deproteinizing a carapace of a Crustacea using a fatty acid sodium salt, subsequently treating the deproteinized carapace with hydrochloric acid and to safely produce chitosan by further treating the obtained chitin with sodium hydroxide as necessary. CONSTITUTION:Chitin is obtained by (A) adding a fatty acid sodium salt (about 1wt.% based on stock solution), preferably a fatty acid sodium salt and sodium carbonate to a carapace of a Crustacea such as a lobster or a crab so as to bond the fatty acid sodium salt to the protein, removing the bonded substance in the form of waste water for deproteinization and subsequently (B) treating the residual material with hydrochloric acid (2N) for decalcification treatment. Chitosan is obtained by (C) treating the resultant chitin-containing solution with a high-concentration sodium hydroxide. This invention enables the objective safe and efficient production of chitin or chitosan from a carapace of a Crustacea without using sodium hydroxide in deproteinization treatment.

Abstract: PURPOSE:To obtain a stable output against a change in the temperature and in the component characteristic by adopting the same circuit constitution relating to a constant current source of the operating side of an analog switch circuit and the constant current source of a buffer amplifier circuit so as to facilitate the design. CONSTITUTION:The buffer amplifier circuit consists of transistors(TRs) Q10, Q13, Q14 and resistors R10, R11, R12 and the constant current source of the TR Q10 consists of the TRs Q13, Q14 and the resistors R10, R11, R12 in a multiplexer circuit. The constant current source is provided so as to be of the same constitution as the constant current source is at the operating side of an analog switch circuit. Since the circuit is constituted as above, a current flowing to the TR Q9 and a current flowing to the TR Q10 are always in the same relation even if the temperature change or component characteristic varies or even if a clamp voltage is changed. Thus, the design of the constant current source is facilitated and a stable output is obtained against the temperature change and deterioration in the component characteristic.
