IPC: D01F6/14
Filed: 1987-09-18
Abstract: PURPOSE:To obtain in high productivity the titled yarn with high strength and high initial modulus, also free from mutual fiber sticking, by dry-wet spinning of a stock solution prepared by dissolving PVA in a mixed solvent made up of dimethylsulfoxide and water, followed by applying specific treatment. CONSTITUTION:First, PVA is dissolved in a solvent consisting mainly of a mixture of dimethylsulfoxide and water to prepare a spinning stock solution followed by dry-wet spinning of this stock solution to form (undrawn) yarn. Thence, the residual solvent in said yarn is extracted with either a mixture of alcohol (pref. methanol) and water or another mixture of ketone (pref. acetone) and water to obtain a water-contg. yarn. This yarn is subsequently wet- drawn by a factor of 3-8 followed by dry heat drawing, thus obtaining the objective yarn. The water content in said water-contg. yarn is pref. 0.2-20wt.%.

IPC: H04N1/32
Filed: 1985-10-21
Abstract: PURPOSE:To effectively resend a picture signal frame having an error by storing plural picture signal frames and processing the picture signal frame having the error every block. CONSTITUTION:As an example detecting a transmission error in the picture signal PIX2, that the error is present in the picture signal frame PIX2 is informed as a PRR2 by a partial resend request signal PRR to a partial page PPS. Herein, N in PRR(N) indicates a frame number and takes values of 0-7. When there are errors in the plural frames, for example, there are the errors in the picture signal frames PIX3 and PIX5, they can be informed as PRRs 3, 5 and the frame numbers to eight at the maximum. In a transmission side receiving the partial repeat request signal PRR2, only the picture signal frame PIX2 having the error is repeated.
