Abstract:
According to the present invention, since the gravure roller with no load has a radial run out of 15 μm or less in all places of a pattern part in which cells are formed (the gravure plate cylinder) on the surface of the gravure roller, liquid accumulations (beads) are hardly affected by the radial run out of the roller surface, thereby making it possible to prevent coating nonuniformity.
Abstract:
The present invention provides a method of curing a coated film which includes irradiating an active ray by a plurality of active ray irradiation devices, wherein the coated film is composed of an active ray-curable resin formed on a surface of a running band-shaped flexible support, comprising the step of: maintaining the coated film in a deoxidized atmosphere during a period in which the flexible support irradiated with an active ray by the at least one active ray irradiation device is transferred to the active ray irradiation device in a subsequent step.
Abstract:
The coating construction has flexibility corresponding to the number of layers of multiple coating layers, by which a multilayer coating film can be produced with small film thickness without adherence of dust to a film surface, a drying fault such as unevenness induced by drying-wind on the film surface, or a coating fault such as a level variation and a streak. The multilayer coating film has a coating surface state of high quality with coating thickness deviation of 3% or less. A coating device is constructed in which at least a feed roller, a coater and a dryer are integrally incorporated in a casing, and the coating device is given a function as an independent device, whereby the production apparatus of the multilayer coating film can be constructed by only appropriately placing as many coating devices as the number corresponding to the number of layers of the multiple coating layers formed on a web between a delivery device and a winder.
Abstract:
A method for forming multiple coating layers produces a coating construction that has flexibility corresponding to the number of layers of multiple coating layers, by which a multilayer coating film can be produced with small film thickness without adherence of dust to a film surface, a drying fault such as unevenness induced by drying-wind on the film surface, or a coating fault such as a level variation and a streak. The multilayer coating film has a coating surface state of high quality with coating thickness deviation of 3% or less. In the method, a belt-like substrate is continuously fed. A coating/drying step follows, with multiple steps performed in a single unit. A plurality of coating layers are formed by sequentially performing the coating/drying step by multiple units. Finally, the belt-like substrate with the multiple coatings is continuously wound.
Abstract:
Cadaverine dicarboxylate is produced by performing an enzymatic decarboxylation reaction of a lysine solution while adding a dicarboxylic acid containing 4 to 10 carbons to the lysine solution to maintain pH of the solution at a level sufficient for the enzymatic decarboxylation reaction to occur, for example, 4.0 to 8.0.
Abstract:
A cleaning device includes a cleaning blade for scraping out toner from a photosensitive member and a polygonal member for carrying scraped toner into a toner container. A rotation center of a blade holder for supporting the cleaning blade is coincident with a rotation center of the polygonal member.

A method for the crystallization of tryptophan, comprising storing a tryptophan solution at a pH of 8 to 13 and at a temperature of room temperature to 100° C. for 0.5 hour to 1 week and then, followed by crystallization.
Abstract:
In a coating method and apparatus for applying coating liquid onto a web, the coating apparatus includes a rotating member rotatable and contacting with the web; and a support member supporting rotatably the rotating member and including a liquid reservoir formed between the rotating member and the support member, a fluid supply pipe, a cavity filled with the coating liquid and connecting to the fluid supply pipe, and a slit communicating the cavity with the liquid reservoir. The rotating member is supported by a fluid pressure of the liquid reservoir and the coating liquid supplied from the liquid reservoir forms a bead of the coating liquid by the rotating member between the web and the rotating member. The rotating member is floated uniformly in the widthwise direction by the fluid pressure so as to keep a predetermined clearance away from the support member to provide a stable coating. The bead is made uniform in the widthwise direction under any conditions.
Abstract:
The present invention provides A method for producing a recording sheet including the steps of coating and forming a coloring material receiving layer containing inorganic particulates and a water-soluble resin on a band-shaped substrate which is wound and supported on a backup roller and continuously travels, and thereafter, coating and forming a top layer on the coloring material receiving layer in a semidry state, comprising: coating the top layer by an extrusion type coater which coats a coating solution to the surface of the substrate via a bead which is formed between the lip tip end and the substrate with cross-linking the coating solution discharged from a lip tip end of a coating head the surface of the substrate, in a state of pressure of an upstream side of the bead reduced so that a pressure reduction degree with respect to atmospheric pressure is in a range from over 0 kPa to 2.0 kPa by providing a suction chamber at an upstream side of the coating head seen in a traveling direction of the substrate.
