Adhesion, water resistance, recoverability, and whitening resistance after heating are all excellent.

Abstract: A printing cylinder for offset printing includes a cylinder member of a hollow cylinder having a covering portion which forms a substantially uniform, smooth outer circumferential surface having no spliced portion in the circumferential direction, the covering portion being capable of transferring printing images onto an adjacent printing cylinder or printing paper in contact with the covering portion; and printing cylinder support mechanism including a pair of support shafts which are supported on opposed frames such that the support shafts are rotatable about a common axis, the support shafts each having a shaft end portion which is connected to an end portion of the cylinder member via an engagement portion and by use of connection member. The engagement portion includes a groove and a ridge portion formed on the end surface of the cylinder member and the shaft end portion of the corresponding support shaft.

Abstract: A roller assembly positioned downstream of a printing station in a web-fed rotary printing press for pneumatically guiding a web of paper after it has been printed upon, without the risk of smearing the printings. The assembly includes a roller in the form of a hollow cylinder defining a plenum chamber therein and having formed in its surface a multiplicity of air outlet openings in communication with the plenum chamber. Air supplied under pressure to the chamber is therefore expelled from the air outlet openings in order to avoid contact with the roller the web traveling over the rollera baffle encloses at least part of the circumferential part of the roller surface for confining the air being expelled from said at least part of the other circumferential part of the roller surface and for redirecting the confined air into a pair of spaces, spaced, between the web and the roller.

Abstract: A polyamide film satisfying (a) a haze value of not more than 5.0%, (b) a coefficient of kinetic friction (A) of not more than 1.0 under 50% humidity, the coefficient (A) being measured with regard to fiction between the same two polyamide films, and (c) a ratio of coefficients of kinetic friction (B)/(A) of not more than 1.5, the (B) being a coefficient of kinetic friction at 65% humidity, a billy oriented polyamide film showing an average dimensional change of not more than 3.0% and a difference between the smallest dimensional change and the largest dimensional change of not more than 2.0%, between before immersion in hot water at 95° C. and during the immersion, and an average dimensional change of not more than 4.0% and a difference between the smallest dimensional change and the largest dimensional change of not more than 2.0%, between the film without treatment and the film after withdrawal from said hot water; and a polyamide laminate film containing the film as a substrate layer.

Abstract: A plate cylinder has formed therein a groove extending parallel to the cylinder axis and having a depth direction thereof set at an angle to a plane tangent to the plate cylinder at the groove, so that the opposite sides of the groove are at acute and obtuse angles, respectively, to that plane. For use with this plate cylinder, the printing plate has two staggered series of spaced lugs formed on a pair of meeting edges of its image-bearing major part. The two series of lugs are bent at approximately the same acute and obtuse angles, respectively, to the major part as the opposite sides of the groove are to the tangential plane. For mounting the plate to the cylinder, the acute-angled series of lugs of the plate are first inserted in the groove in the cylinder so as to hook these lugs onto the acute-angled leading side of the groove. Then the plate is wrapped around the cylinder by rotating the same in a prescribed direction.

Abstract: The present invention provides a blood-compatible composition containing an ionic complex consisting of an organic cationic compound and heparin or a derivative thereof, wherein the organic cationic compound is an ammonium or a phosophonium bound with four aliphatic alkyl groups, the four aliphatic alkyl groups having a total number of carbon atoms of 24 to 32, and has at least 2 alkyl groups having not less than 10 carbon atoms. A medical device capable of long-term sustention of antithrombogenicity can be produced by coating the surface of the medical device with the composition.

Abstract: A thermoplastic laminate film containing a thermoplastic substrate film and a layer formed from a resin composition containing a polyester graft copolymer (A) and a resin (B), the layer being formed on at least one side of the thermoplastic substrate film, the polyester graft copolymer (A) being obtained by grafting at least one polymerizable unsaturated monomer, which contains an acid anhydride having a double bond, to a hydrophobic polyester resin, and the resin (B) containing at least one member selected from the group consisting of a polyurethane resin, an acrylic resin and a vinyl resin. The adhesion improving layer of the inventive thermoplastic laminate film shows superior adhesion strength in a broad range of applications.

Abstract: A tower type multi-color printing press has heating means which is constructed in compact and simple in structure to require lesser space for installation, to lower production cost, to facilitate inspection and maintenance and to reduce frequency of occurrence of failure. The tower type multi-color printing press includes a plurality of printing sections provided with stacking in vertical direction, and heating means provided on downstream side of each printing section and extending in a width direction of a paper web fed through a path across each printing section, for heating a printed surface of the paper web every time completing the printing in each printing section.

Abstract: The rolling mill includes upper and lower work rolls, a roll bending apparatus for applying a bending force to the upper and lower work rolls, a roll shifter for axially shifting the upper and lower work rolls in opposite directions, and a back-up roll for supporting the upper and lower work rolls. The upper and lower work rolls have a bus having a contour comprising first to fifth regions. The rolling mill is adapted to have the large changability of plate crown effected by the roll shifting on plates with narrow or intermediate widths. The use of a combination of roll shifting and roll bending causes contours of the upper and lower work rolls to overlap deflection of the upper and lower work rolls, resulting in that a smooth roll diameter profile across the width of the plate to be rolled where the upper and lower work rolls contact the plate.
