Title: Recovery of monomer
Inventor: HISATANI KUNIO
IPC: B01D3/38
Filed: 1985-03-12
Abstract: PURPOSE:To simply and economically recover a monomer from a polymer suspension or dispersion containing an org. polymer up to 50wt%, by utilizing a column packed with a packing material having a specific structure in a definite range of a volume/space ratio. CONSTITUTION:A polymer suspension or dispersion containing an org. polymer up to 50wt% is flowed downwardly through a column packed with a packing material, which is a perforated hollow structure capable of being received in a sphere with a diameter of 20-300mm, so as to set the volume/space ratio thereof to 50% or more on the basis of the total packing volume. In order not only to prevent the sedimentation of the polymer by holding the transmitted solution to a sufficient mobile state but also to move the unreated monomer in said solution to a gaseous phase by utilizing gas-liquid equilibrium relation before recovering the same, steam is flowed upwardly through the column so as to be countercurrently contacted with said solution.

Title: Receiving circuit
Inventor: ARAI MASANOBU
IPC: H04B3/06
Filed: 1987-03-02
Abstract: PURPOSE:To prevent an error in an adaptive decision feedback equalizing circuit from being increased even with a long frame pattern interval by detecting the deciding error of a received symbol string and intermitting temporarily the adaptive operation of the adaptive decision feedback equalizing circuit according to the result of detection. CONSTITUTION:In receiving the notice of deciding error detection from a deciding error detection circuit 2, a control circuit stops the correction of a tap coefficient through a control line l3. The stop of the tap coefficient correction goes to a period to receive the next frame pattern and continues even when the known frame pattern is being inputted to a delaying element 8. As long as a correct frame pattern is set to the element 8 and the tap coefficient holds a correct value, since the possibility of generating the effect of error by an adaptive decision feedback equalizing circuit 1 is very small, the equalizing circuit 1 is normally restarted from a point of time when the first data symbol is received.
