Abstract: A gravure printing device includes a substrate stage (11) on which a substrate (2) is fixed, an intaglio plate (21) for holding conductive paste, and a control device (7) for controlling a series of printing operations including a supply operation of supplying conductive paste (3) to a printing pattern of the intaglio plate (21) and a transfer operation of transferring the conductive paste (3) to the substrate (2). The control device (7) repeatedly performs the series of printing operations a plurality of times with respect to the identical printing position on the substrate (2). A printing pattern laminate made of the conductive paste laminated into the shape of the printing pattern is formed on the substrate (2). This makes it possible to form lines and bumps on a substrate made of a heat-sensitive material, while preventing the occurrence of metamorphosis of the substrate made of the heat-sensitive material.

Abstract: A flexible-electronic-device manufacturing apparatus for manufacturing an electronic device including a flexible base material and a plurality of functional layers provided thereon includes: an impression cylinder configured to hold and transport the base material; impression-cylinder driving means for rotating the impression cylinder; processing means for performing a plurality of processes for providing the plurality of functional layers by a printing method or a coating applying method on the base material held on the impression cylinder; impression-cylinder phase detecting means for detecting the phase of the impression cylinder; and controlling means for controlling the impression-cylinder driving means and the processing means based on the result of detection by the impression-cylinder phase detecting means.

Abstract: In a coating apparatus including: an anilox roller which is rotatably supported and in which multiple recessed cells are formed on an outer peripheral surface; and a chamber device which is in contact with the outer peripheral surface of the anilox roller and in which varnish to be coated on a sheet is delivered from a delivery path of a chamber head into a chamber, the chamber device configured to supply the delivered varnish from the chamber to the cells of the anilox roller and discharge the varnish in the chamber from a discharge hole of a chamber body to the outside, the chamber device has pressure fluctuation reducing means, in an attachment hole of the chamber body, for reducing a pressure fluctuation in the chamber of the chamber head in such a way that the pressure in the chamber is maintained constant.

Abstract: A powdering device includes: a powder placing member having a placing section on which a powder fed from a storage container is placed; a first scraping member for scraping the powder on the placing section of the powder placing member, so that a constant amount of the powder remains on the placing section; and a second scraping member for scraping off the resultant constant-amount powder remaining on the placing section, and the powdering device transfers the scraped powder with an air flow, and sprays the powder thus transferred onto a printed sheet.

Abstract: Disclosed is an apparatus-information indicator, which includes an indication surface, an underlying segment formed on the indication surface by a first dot pattern, and a character area formed on the underlying segment by a second dot pattern different from the first dot pattern to indicate given apparatus information. Respective colors of the underlying segment and the character area are substantially equal in hue, and substantially different in lightness.

Abstract: A dust collection apparatus of a printing press comprises: delivery chains equipped with gripper devices for holding a printed sheet; spray nozzles for spraying a powder toward a printed surface of the sheet being transported by the delivery chains; a blowing device, provided downstream of the spray nozzles in a sheet transport direction, for blowing air nearly parallel to the printed surface of the sheet being transported and toward an upstream side in the sheet transport direction; and a suction duct, provided upstream of the blowing device in the sheet transport direction, for sucking the powder along with air blown by the blowing device.

Abstract: A powder apparatus for a sheet-fed rotary printing press includes a nozzle, valve, state detection unit, arithmetic operation unit, and controller. The nozzle sprays powder onto a printed surface of a sheet delivered after printing. The valve adjusts a quantity of powder sprayed from the nozzle. The state detection unit detects a quantity of powder attaching to the sheet. The arithmetic operation unit and controller control the valve on the basis of data output from the state detection unit and indicating a powder quantity.

Abstract: A rotary valve is interposed between an intake pump and an exhaust pump for supplying an air, and at least one suction head or one nozzle that performs a predetermined operation upon reception of the air supplied from the intake and exhaust pumps, to supply/stop supplying the air. This rotary valve includes a valve body, a main body, a notch, and a hollow portion. The valve body is rotatably driven in a cylinder. The main body rotatably supports the valve body. The notch is formed in a circumferential surface of the valve body and is connected to the intake pump. The hollow portion is formed in the valve body in an axial direction and is connected to the exhaust pump.
