| 20090079808 | INTERMITTENT APPLICATION METHOD AND APPARATUS, AND INKJET RECORDING METHOD AND APPARATUS - The intermittent application method of intermittently applying an application liquid to a continuously conveyed band-shaped or cut-sheet-shaped supporting body, includes the step of causing a lower surface of the supporting body, and a circumferential surface of an application cylinder which takes up the application liquid from an application liquid reservoir by rotation, to make contact with each other and separate from each other in a relative manner by means of a cam mechanism in such a manner that an application section where the application liquid is applied, and a non-application section where the application liquid is not applied, are formed on the lower surface of the supporting body. | 03-26-2009 |
| 20090084311 | LIQUID APPLICATION APPARATUS AND INKJET RECORDING APPARATUS - A liquid application apparatus applies application liquid onto a band-shaped base material that is conveyed continuously. The liquid application apparatus includes: an application cylinder which includes an application section and two small diameter sections having a diameter smaller than the application section, the two small diameter sections being arranged so as to interpose the application section, the application section having an upper portion that is in contact with the band-shaped base material and a lower portion at which the application liquid is supplied, the supplied application liquid on the application section being transferred to the band-shaped base material at the upper portion of the application section while the application cylinder is rotated; a first blade which makes contact with a circumferential surface of the application section of the application cylinder at a contact line, the first blade scraping away an excess of the application liquid on the application section of the application cylinder before the application liquid is transferred to the band-shaped base material; and a second blade which is in contact with circumferential surfaces of the two small diameter sections of the application cylinder. | 04-02-2009 |
| 20110050801 | CLEANING DEVICE, LIQUID APPLICATION DEVICE AND IMAGE FORMING APPARATUS - The cleaning device includes: a wiper blade which is arranged along an axial direction of a pressure drum holding and conveying a medium on which liquid is applied, the pressure drum holding the medium on a pressure drum circumferential surface of the pressure drum and conveying the medium in a prescribed medium conveyance direction, the wiper blade wiping and removing the liquid adhering to the pressure drum circumferential surface, the wiper blade being disposed in such a manner that a wiper blade face of the wiper blade is inclined from a normal to the pressure drum circumferential surface at a contact position with the wiper blade face to form an angle of smaller than 90° between the wiper blade face and the pressure drum circumferential surface on an upstream side from the contact position in terms of the medium conveyance direction; a movement device which moves the wiper blade so as to separate the wiper blade from the pressure drum circumferential surface when a gripping member arranged on the pressure drum to hold an end portion of the medium passes a wiping process position of the wiper blade; and a liquid pool removal device which removes at least a portion of the liquid in a liquid pool formed by the liquid that has been wiped by the wiper blade immediately before the wiper blade is separated from the pressure drum circumferential surface and that has not slid completely down the wiper blade face. | 03-03-2011 |

| 20080273184 | APPARATUS AND METHOD FOR REFERENTIAL POSITION MEASUREMENT AND PATTERN-FORMING APPARATUS - A digital exposure apparatus for forming a pattern on a topside surface of a substrate has an alignment unit, which detects a position of the substrate from image data obtained through a camera from a reference mark provided on the topside surface of the substrate. The alignment unit further has a Z-direction sensor to measure a fluctuation amount Δ of the topside surface of the substrate from a predetermined focal plane of the camera. Depending upon the measured amount Δ, a set of distortion correction data is selected from or calculated on the basis of previously stored distortion correction data. The image data of the reference mark is corrected with the selected or calculated distortion correction data, so that errors induced by the fluctuation from the focal plane are corrected without adjusting the position of the substrate in the direction of an optical axis of the camera of the alignment unit. | 11-06-2008 |
| 20090059297 | CALIBRATION METHOD FOR IMAGE RENDERING DEVICE AND IMAGE RENDERING DEVICE - A calibration method for an image rendering device is provided which calibrates offset in the direction around an optical axis of an alignment camera and enables improvement of the accuracy of correction of image rendering offset relative to an image rendering medium. A calibration reference mark is photographed by an alignment camera and the amount of rotation of the alignment camera around its optical axis is calculated using coordinate data for the calibration reference mark in the camera field of view. Based on the calculated data, the readings taken by the alignment camera during alignment are corrected. | 03-05-2009 |
| 20090092288 | IMAGE POSITION MEASURING APPARATUS AND EXPOSURE APPARATUS - An image position measuring apparatus is provided with a photographing unit including an image pickup device and/or a lens to measure a position of a reference mark formed on a work and a correcting unit for correcting distortion(s) of the image pickup device and/or the lens. An exposure apparatus is provided with an image position measuring apparatus and an exposure unit for exposing the work based on image data corrected based on positional information of the reference mark photographed by the image position measuring apparatus. Influences of the distortions of the image pickup device and the lens can be eliminated and accuracy of measurement of the position of the reference mark provided to the work can be improved. | 04-09-2009 |

The storage component stores drying information, including information representing a pre-drying moisture amount previously derived by the first moisture amount derivation component, and a drying strength of the drying component at which a recording medium was dried when the previously derived pre-drying moisture amount was derived. The control component controls the drying strength of the drying component on the basis of the pre-drying moisture amount derived by the first moisture amount derivation component and the drying information stored by the storage component. | 10-01-2009 |
