Abstract:
A controlled release composition containing a physiologically active substance in high content, suppressing the initial excess release, and achieving a stable release speed over a long period of time is provided. A controlled release composition comprising (1) a physiologically active substance or salt thereof in an amount of about 14% (w/w) to about 24% (w/w) based on the total composition weight, (2) hydroxynaphthoic acid selected from the group consisting of 3-hydroxy-2-naphthoic acid and 1-hydroxy-2-naphthoic acid or salt thereof, and (3) a lactic acid polymer or salt thereof having a weight-average molecular weight of 15000 to 50000 in which the content of polymers having molecular weights of 5000 or less is about 5% by weight or less, wherein the molar ratio of said hydroxynaphthoic acid or salt thereof to said physiologically active substance or salt thereof is from 3:4 to 4:3.

Abstract:
There is provided a production management system that requires no backup step for performing a backup operation when trouble occurs in a robot, and can increase workability of a repair operation of the robot. The production management system for a production line mixedly including robot operation steps and manual operation steps, including: a monitor that displays the cause of abnormality that occurs in the robot operation step; a warning device that warns of occurrence of abnormality in the robot operation step; and a robot reversing device that reverses the orientation of a robot when abnormality occurs in the robot, wherein production is continued by changing the robot operation step where the abnormality occurs to the manual operation step. Also, a repair operation is performed for the robot reversed by the robot reversing device.

Abstract:
A sustained-release composition containing a hydroxynaphthoic acid salt of a biologically active substance and a biodegradable polymer, a method of its production, and a pharmaceutical composition containing said sustained-release composition.
Abstract:
Present invention is to provide a sustained-release composition which contains a physiologically active substance in high content even when gelatin is not included, and suppresses its initial excessive release and, thus, can achieve a stable release rate over about one month. A sustained-release composition containing a lactic acid-glycolic acid polymer having a ratio or weight average molecular weight and number average molecular weight of about 1.90 or lower, or a salt thereof, and a physiologically active substance.
