  • Publication number: 20240128020
    Abstract: In a method for manufacturing a laminated coil component, in which a laminated coil component is manufactured by laminating insulator sheets in order on which conductors having predetermined patterns are formed, the insulator sheets are laminated such that a distance in a lamination direction between a first lead-out conductor laminated first and a first coil conductor laminated next is larger than a distance in the lamination direction between a second lead-out conductor laminated last and a second coil conductor laminated immediately before the second lead-out conductor.

  • Patent number: 7630664
    Abstract: A cleaning device of a charging roller has: a cleaning member contacting a charging roller which charges an image carrier which carries an image, and cleaning a surface of the charging roller; and a holding structure holding the cleaning member such that the cleaning member is movable at least between a first position and a second position along a peripheral direction of the charging roller. The holding structure holds the cleaning member such that an amount of compression of the cleaning member at a contacting portion of the charging roller and the cleaning member is greater at the second position than at the first position.

  • Patent number: 7529498
    Abstract: An image forming device includes a charging roller that charges a body-to-be-charged by press-contacting and is rotated by the rotating body-to-be-charged, a first receiving portion that supports a supporting portion provided at the charging roller, and causes the charging roller to press-contact the body-to-be-charged, a cleaning member that press-contacts a surface of the charging roller and cleans the charging roller, and a second receiving portion that supports a supporting portion provided at the cleaning member, and causes the cleaning member to press-contact the charging roller. At least one of the first and second receiving portions imparts a degree of freedom at a first receiving portion side to the supporting portion of the charging roller in a direction of press-contacting the body-to-be-charged, and imparts a degree of freedom at a second receiving portion side to the supporting portion of the cleaning member in a direction of press-contacting the charging roller.

  • Patent number: 7340194
    Abstract: An image generation managing system includes an image forming apparatus provided in a management target area to form a color image on a recording medium, an image capturing apparatus to capture an image in a vicinity of the image forming apparatus in the management target area, and a job management device connected to the image forming apparatus and the image capturing apparatus over a network to data-communicate therewith to manage an image generating job by the image forming apparatus. Preferably, the image forming apparatus includes a specific pattern imparting unit to impart a specific pattern specifying an image formed for each image generating job by the image forming apparatus, and the job management device includes a database in which the specific pattern information and the image data captured are stored in a state they can be associated to each other and from which the stored information is freely retrieved.

  • Patent number: 7214330
    Abstract: A method of manufacturing a highly crystallized phosphor powder, comprising: making a raw material solution containing metal elements and/or semimetal elements that will be constituents of the phosphor into fine liquid droplets, subjecting the liquid droplets to decomposition by heating at a temperature of 500 to 1800° C. to produce hollow precursor particles and/or porous precursor particles, heating the precursor particles to crystallize the precursor particles while maintaining the hollow or porous form, and grinding the crystallized particles down to a predetermined particle size. The obtained phosphor powder is a high luminance inorganic phosphor powder that is extremely fine, and yet has few defects on the surface of or inside the powder, and hence has excellent crystallinity and light emission characteristics, and provides a phosphor composition useful for producing a phosphor layer with high coverage and high luminance of light emission.
