  • Patent number: 8075361
    Abstract: A constitution that conductive members respectively having micropatterns are arranged in high density is manufactured in high accuracy. A conductive film is formed on a substrate, a negative photosensitive resin is applied, the applied resin is exposed by using a first mask having plural fine-width apertures extending in Y direction, and the resin is then exposed and developed by using a second mask having plural apertures extending in X direction perpendicular to Y direction, thereby forming a first resist. After the conductive film is etched by using the first resist as a mask, a negative photosensitive resin is again applied, and exposure and development are performed as shifting the second mask in Y direction, thereby forming a second resist. The conductive film is etched by using the second resist as a mask to eliminate unnecessary areas, thereby forming the conductive film having minute-lines extending in Y direction.

  • Patent number: 7588306
    Abstract: A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle around (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle around (2)} and {circle around (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.

  • Patent number: 7564037
    Abstract: An image sensor has a plurality of pixels, each pixel including a photoelectric converter and a pixel circuit for processing signals from the photoelectric converter and outputting processed signals and a scanning circuit, disposed between the photoelectric converters, included in each of at least two adjacent pixels among a plurality of pixels aligned in a single direction. An edge pixel accommodates, in order from an edge of the image sensor toward an interior, a predetermined empty region, a photoelectric converter and a pixel circuit. There is at least one position at which two adjacent pixels, the first of the two pixels accommodating, in order, a pixel circuit, a photoelectric converter and predetermined empty region, the second accommodating, in order, a predetermined empty region, a photoelectric converter and a pixel circuit. The scanning circuit is disposed in the predetermined empty region between the two adjacent pixels.

  • Patent number: 7014969
    Abstract: The present invention provides a silica fine particle capable of preventing a charging member or an image bearing member from being contaminated with toner when the toner contains the particle and also capable of providing the toner with a stable developing property. The silica fine particle of the present invention has been hydrophobic treated. Furthermore, the particle has a peak in a range of 0.04 ?m to 1 ?m and a peak in the range of 1 ?m to 100 ?m in a volume-basis particle diameter distribution. The particle has a frequency ratio of 10 to 80% for the particles with a particle diameter of 0.04 ?m to 1 ?m to a total of all the peaks, and the particles has the frequency ratio of less than 16% for the particles with a particle diameters of 20 ?m to 2000 ?m to the total of all the peaks.
