Abstract:
A sheet feeder includes a support to support a roll sheet winding a sheet, a sensor that is at a first position on the support and contacts a surface of the roll sheet to detect a level difference at a trailing edge of the roll sheet and output a first signal and a second signal, a roller that is at a second position different from the first position in a circumferential direction of the roll sheet on the support and contacts the surface of the roll sheet to guide the roll sheet, and circuitry to cause the roll sheet to rotate in a sheet feeding direction to feed the sheet, and detect the trailing edge of the roll sheet based on the first signal output from the sensor, and the second signal output from the sensor.
Abstract:
An image processing apparatus includes a plurality of compression units and a switching unit. The plurality of compression units compress image information by different compression methods. The switching unit extracts plural pieces of color information from pieces of color information which constitute the image information in a color space expressing the image information, and selects one of the plurality of compression units in accordance with hue angles of the plural pieces of extracted color information.
Abstract:
To supply substantially isolated neural cells in a large amount, and to provide an application means for a neuroregenerative medicine or the like for a neurodegenerative disease, a nervous damage or the like. A method for producing a substantially isolated neural cell, comprising the step of carrying out the suspension culture of embryonic stem cells in the presence of an astrocyte conditioned medium or ingredients substantially equivalent to the conditioned medium; and a neural cell obtained thereby; a cell pharmaceutical composition comprising, as an active ingredient, the isolated neural stem cell; and a method for treating a neurodegenerative disease or nervous damage, comprising the step of introducing the neural cell into a neurodegenerative site or a nervous damage site.
Abstract:
A sheet carrier apparatus includes a sheet carrier guide to guide a sheet in a first direction and includes an opening; and a paper-dust removal member that is arranged substantially above the opening and so as to make a contact with the sheet carried on the sheet carrier guide, is extending in a second direction orthogonal to the first direction, and removes paper dust so that the paper dust falls through the opening. In the sheet carrier apparatus, the paper-dust removal member includes a first part and a second part that are arranged along the second direction, and the first part and the second part have a different contact resistance against the sheet.
Abstract:
A medium discrimination device includes a transmitted light quantity measurement device arranged to measure a transmitted light quantity in a thickness direction of a medium on a conveyance route, and configured to perform a measurement of the transmitted light quantity at each time the medium is conveyed, a measurement value memory device storing a result of the measurement performed by the transmitted light quantity measurement device, a medium setting device configured to previously set a type of medium to be used, a medium information memory device storing information of a transmitted light quantity assigned to each medium to be set by the medium setting device, and a control processing unit configured to perform paper type detection on a first medium, and double feed detection on following mediums.
Abstract:
A sheet conveying unit that guides and conveys a sheet material by a lower conveying guide includes an opening in the lower conveying guide, a brush-like member on a downstream side of the opening to scrap off paper dust adhered on a surface of a sheet material.
Abstract:
A red emitting phosphor having a low luminous reflectance, comprising a rare earth element-based phosphor body activated by europium and a red pigment coated on the phosphor body, is disclosed, the pigment being formed of indium sulfide or of a combination of indium sulfide and an alkali metal sulfate. The phosphor is produced by coating the phosphor body with a complex compound containing of indium sulfide and an alkali metal sulfide, followed by baking in an oxygen containing atmosphere at 400.degree. to 600.degree. C. so as to convert the complex compound into a red pigment consisting of indium sulfide and an alkali metal sulfate.
Abstract:
An image processing apparatus includes: a limited color conversion processing section that extracts a plurality of pieces of color information making up image information and executes conversion to specific colors to which the color information belongs; a by-color separation processing section that separates for each specific color, image information converted into the specific colors by the limited color conversion processing section; a compression processing section that compresses for each color, the image information for each specific color separated by the by-color separation processing section; and a layered structure forming processing section that collectively outputs the image information for each color compressed by the compression processing section.
Abstract:
An image processing apparatus is provided, the image processing apparatus including: a limited color conversion processing section that extracts plural pieces of color information constructing image information and converts the plural pieces of color information into color information representing specific colors to which each of the plural pieces of color information belongs; a by-color separation processing section that separates the image information containing the converted color information for each of the specific colors; a compression determination section that determines a compression system for each color as to each of pieces of image information which are separated by the by-color separation processing section for each of the specific colors; a compression processing section that compresses said each of pieces of image information according to the determined compression system for each color; and a layered structure forming processing section that collectively outputs said each of pieces of image information compressed.
Abstract:
A sheet transport device and an image forming apparatus that includes the sheet transport device. The sheet transport device includes a reverse-transport roller, at least one roller guide, and a shaft. The reverse-transport roller is provided to a diverging point of a sheet reversing portion from which a recording medium enters or exits and is configured to transport the recording medium to the sheet reversing portion. At least one roller guide is provided in a vicinity of an end face of at least one side of the reverse-transport roller and is configured to prevent the reverse-transport roller from contacting the recording medium when reversing the recording medium. The reverse-transport roller and the roller guide are disposed on the shaft. Friction of a peripheral surface of the roller guide is configured to be substantially less than that of the recording medium.
