Title: Method for lowering molecular weight of aliphatic polyester and molding the same
Inventor: KURACHI KAZUHITO
IPC: C08G63/91
Filed: 1990-03-28
Abstract: PURPOSE:To lower the molecular weight of an aliphatic polyester to a specified degree simply at good efficiency by reacting the aliphatic polyester with an ester compound. CONSTITUTION:An aliphatic polyester is reacted with an ester compound. As the aliphatic polyester, a polyester produced microbially is desirable. The above reaction can be performed in the presence or absence of a solvent which can dissolve the aliphatic polyester at a temperature higher than the melting point of the aliphatic polyester or can be performed under reflux of a solvent. The lowered molecular weight polyester obtained by reacting the ester compound in the absence of any solvent can be molded as such without cooling after the reaction. A solution of the lowered molecular weight polyester obtained by reacting the ester compound in the presence of a solvent can be formed into a film when it is cast after cooling. Examples of the above ester compounds include esters of lower aliphatic acids such as acetic acid and propionic acid with lower alcohols such as methanol and ethanol.

Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To efficiently generate data packets in the state of a stream by successively outputting the stream-state data packets of the same number as the value of data of inputted data packets. SOLUTION: In the case that data packets where data D is 6, e.g. are inputted, data packets an RPT instruction 34 outputs onto a path 35 become six data packets (D=5 to 0) where a line number LN# and a pixel number PX# are fixed (5, 1) and where data D is subtracted one by one from 5 to 0. In addition, data packets outputted to a path 36 from a instruction 34 are similar to those outputted to the path 35 but a final data packet (D=0) is not outputted. As the result of it, the loop-like execution of the instruction 34 finishes by five times. Namely, this device executes the instruction 34 by the same number as the value (6) of data D of a data packet inputted first and outputs a corresponding number of data packets onto the path 35.
