Title: Dicarboxy-terminated oligomer, bisimidazoline- added polymerand copolymer and their production
Inventor: TOOMA FUISUSHIE
IPC: C08G65/332
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To prepare high molecular weight polymers represented by a specific formula with high purity by the addition reaction of a specific oligomer with a bisimidazoline under specific conditions.  
     SOLUTION: An oligomer of formula I and an imidazoline of formula II are subjected to a bulk addition reaction at a temperature of higher than the melting point of the oligomer under atmospheric pressure. This reaction is carried out at a temp. of 100-350°C in an inert atmosphere for 1-120 minutes such that the viscosity of the oligomer is rendered not higher than 500 Pa.s in order to disperse chain coupled molecules into the oligomer to be mixed or solubilized therein. Polymers and copolymers containing repeating units of formula III (wherein R is a single bond or a linear hydrocarbon chain; R' is a (substituted) aliphatic hydrocarbon chain having at least two or three carbon atoms which connects the adjacent two -NH groups) can be obtained. Heretofore, to obtain high molecular weight polymers, the reaction has to be operated for a very long period of time and, simultaneously, at high temperatures under reduced pressure, and there has been a danger of deterioration by secondary reactions but this can be prevented.

Title: Method and apparatus for generating digital base band data signal stream
Inventor: MASHIYUU ODONERU
IPC: G10K11/34
Filed: 1988-06-01
Abstract: PURPOSE: To reduce a memory which generates proper time delay by lowering a sample speed. CONSTITUTION: The amplitude of an analog signal input is converted into a stream of digital data words at a maximum conversion speed equal to a 2nd speed of F samples per second in response to a sample strobe S signal. The stream of the data words is demodulated into digital form to find the stream of base-band data words, and respective streams of base-band data words are passed through digital low-pass filters 26-1-26-2. Then the streams of the filtered data words are reduced by a selected subtrahend coefficient D to find an output signal which is a stream of data words generated at a reduced 1st speed of F' samples per second. Consequently, the operation speed and the necessary depth of a channel time delay RAM can be reduced.
