Title: Manufacture of homopolymer or copolymer of water-soluble vinyl monomer
Inventor: KONDO AKIHIRO
IPC: C08F4/40
Filed: 1987-02-03
Abstract: PURPOSE:To continuously produce a (co)polymer of a water-soluble vinyl monomer with good efficiency and controllability, by forming a thin-film flow of an aqueous solution of a water-soluble vinyl monomer and a reductive sulfur- containing oxyacid salt on the inner wall of a reaction cylinder. CONSTITUTION:An aqueous solution of a water-soluble vinyl monomer (e.g., acrylamide) 1 except alpha,beta-unsaturated carboxylic acid monomers and a reductive sulfur-containing oxyacid salt (e.g., sodium hydrogensulfite) 3 is supplied into a reaction cylinder 10 comprising a (double)cylinder from an inlet 12. Simultaneously, an oxygen-containing gas 2 as a parallel flow to the aqueous solution is supplied into the reaction cylinder 10 from an inlet 11 to form a thin film flow of the aqueous monomer solution on the inner wall of the reaction cylinder 10 by a stream of the gas 2 to react. Then, the resulting (co)polymer of the water-soluble vinyl monomer is separated in a gas/liquid separation cooling part 4, cooled, and removed via an aging part 5 and a pH control part 6.

Title: Device and method for manufacturing film screen
Inventor: TAKAHASHI YOSHIKI
IPC: G03B21/62
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent the horizontal movement and/or thermal behavior of a base film from occurring and to enhance the positional accuracy of an optical element formed on both surfaces of the base film by fixing first and second molding rolls and the base film when the base film is moved to the second molding roll from the first molding roll. SOLUTION: Rings with pins 12b provided with many pins 12b-1 are inserted and fixed to the small-diameter parts 12a of both end parts of the second metallic mold roll 12. Then, the base film 101 is moved to the roll 12 from the first metallic mold roll 11. At this time, the metallic pins 12b-1 of the rings 12b fixed to both ends of the roll 12 pierce through the film 101 and they are stuck in the receiving ring made of rubber 11c of the roll 11. Thus, since the roll 11, the film 101 and the roll 12 are integrated and positioned, the film 101 does not shrink caused by the horizontal movement and the thermal behavior with respect to the rolls 11 and 12.
