IPC: A61K8/73
Filed: 1979-04-05
Abstract: PURPOSE: To prepare chitin powder having high purity and useful for medical supplies etc. under mild conditions, economically, by dissolving crude chitin in sulfuric acid of a specific concentration to remove impurities, and carrying out the recrystallization of chitin with sulfuric acid of a concentration below a specific concentration.  
     CONSTITUTION: Natural resources (e.g. crusts, shells of lobsters, etc.) are delimed and deproteinized in order with hydrochloric acid and caustic soda respectively, to give crude chitin. It is dissolved in 45W74% sulfuric acid and the solution is filtered with a glass filter, etc. to remove impruities. The filtrate is diluted with water to attain a sulfuric acid concentration of ≤30% and consequently powdery chitin deposits to give the suspension. The deposit is filtered and washed repeatedly until the effluent becomes neutral. The desired compound having the particle size of ≤100μ is obtained.

Title: Telephone device
Inventor: SHIBAZAKI TETSUO
IPC: H04M1/00
Filed: 1989-02-21
Abstract: PURPOSE:To enable incoming arriving next to be accepted by sending a dry command signal to a slave set when detecting the no voltage of a telephone line for constant time, and setting a master set at a standby state by receiving a dry processing completion signal from the slave set. CONSTITUTION:When a state is set at a speech state, a hook relay 3 is turned on, and the DC loops of the master set A and the slave set B are set at closed states. When such state continues for the constant time and an opponent performs on-hook, the telephone line is set at a no voltage state. When a dry detection circuit 4 detects the fact, the control part 5 of the master set A sends the dry command signal to the slave set B. The slave set B receiving the signal performs a processing to set the standby state, and also, returns a signal representing the completion of the processing. The master set A receiving the signal recovers the relay 3, and sets itself at the standby state by performing a processing to search a null speech channel periodically.

Abstract: PURPOSE:To improve the operability of a document preparing device by separating forcibly a line having the positional relation with a ruled line from another line preceding the first line into different paragraphs and adding the logical information showing the positional relation between the ruled line and its related line. CONSTITUTION:A document preparing system includes a text control mechanism 25, a ruled line control mechanism 26, and a text/ruled line interlocking designation mechanism 27. A line having the positional relation with a ruled line is forcibly separated from another line preceding the first line into different paragraphs.
