Abstract: PURPOSE:To obtain a block copolymer useful as a binder, surface-treating agent, etc., on an industrial scale at a low cost, by using a ketone peroxide having a specific structure as a radical polymerization initiator and carrying out the polymerization by a two-stage polymerization process. CONSTITUTION:The objective block copolymer is produced by using a polymerization initiator consisting of methyl isobutyl ketone peroxide containing >=70% of the organic peroxide of formula and carrying out the polymerization by two-stage polymerization process. The two-stage polymerization process preferably comprises the 1st stage polymerization of one or more monomers at a low temperature in the presence of a reducing agent acting exclusively to hydroperoxy group and inducing redox reaction (e.g., sodium bisulfite or L- ascorbic acid) and the successive 2nd stage polymerization comprising the addition of one or more monomers to the polymerization system maintained at a high temperature to induce the decomposition of the monomer.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of a requester and an answerer at the time of correcting a work sheet in a work sheet distribution/withdrawal system for registering an electronic work sheet by a requester and sending an answer from an answerer receiving the distribution of the work sheet to the requester. SOLUTION: When a client 2 transmits an item correction request to a work sheet registered in an item management server 1, an item correction part 22 corrects a part of a file 11 and corrects the corresponding part of an answered work sheet file 12 for an answerer by referring to a status management table 15 storing information indicating whether each answerer has already answered or not. At the time of being accessed from the client 3, an answer management part 23 transmits the corresponding file 12 or 11 in accordance with the information indicating whether the answerer has already answered or not while referring to the table 15. An answer sent from the answerer is registered in each file 12 of overwritten in an existing file 12 in accordance with judgement whether the answer is the first answer or not.

Abstract: PURPOSE:To transfer an ink so that the phase of a gravure grain can be set off to form a smooth and high-accuracy film with a good linearity of an edge of a body to be printed by a printing method wherein an intaglio printing plate is moved in a printing direction and/or orthogonally to the printing direction by a specific distance. CONSTITUTION:An intaglio printing plate is moved in a printing direction by a formula (y) and/or orthogonally to the printing direction by a formula (x) by an intaglio printing plate roll moving device or an intaglio plate moving device. In the formulas, (x), (y) represent a travel distance ; (p) is a pitch in a bank part of an intaglio printing plate ; (n) is a travel pitch number in irregularities of the intaglio printing plate shown by a integer ; and theta is an angle of the direction of a rotating shaft of a printing roll to the irregularities in a slanting line or lattice form on the surface of the intaglio printing plate. The range is limited, for example, because the movement or rotation of the intaglio printing plate in a direction shown by an integer of x sin theta/p results in the phase of the irregularities being equal to the previous phase invariably. The signs of (n), (x), (y) represent the direction of movement, which is forward if the sign is positive, and reverse if it is negative. In this manner, the surface has a high smoothness and a pattern has a sharp edge.

Abstract: PROBLEM TO BE SOLVED: To decrease a liquid entering into the gap between a main doctor blade and an auxiliary blade by disposing the auxiliary blade on the rear side in the rotational direction of the contact part of main doctor blade while decreasing the interval. SOLUTION: An auxiliary blade 14 employing an nonflammable film is bitten to the lower part of a doctor supporting table 11 in a wiping unit on the rear side in the rotational direction of a wiping roller 6 with respect to the contact part of a main doctor blade 12 and the auxiliary blade 14 is brought into contact with the wiping roller 6 under flexed state. A force acts on the forward end of the auxiliary blade 14 reversely to the rotational direction of the wiping roller 6 due to resiliency of the nonflammable film and prevents a cleaning 5 liquid from creeping over the doctor blade 12 during high speed rotation of the wiping roller 6. Since the liquid entering into the gap between the main doctor blade 12 and the auxiliary blade 14 can be decreased, a product can be protected against contamination.
