  • Patent number: 9717144
    Abstract: There are provided a conductive nanowire network, a conductive board and transparent electrode utilizing it, and a method for producing the same. The conductive nanowire network of the invention has essentially unbroken, continuous conductive nanowires randomly formed into a network. In the method for producing a conductive nanowire network according to the invention, nanofibers are applied in a random network-like fashion onto a substrate covered with a conductive layer, the conductive layer regions that are not covered with the nanofibers are removed, and then the nanofibers are removed. The network structure (wire diameter and network density) are also controlled to obtain a transparent electrode exhibiting both transparency and conductivity.

  • Publication number: 20140010455
    Abstract: According to one embodiment, an image processing apparatus includes an image block generator, a pixel extractor, a correction parameter calculator and a corrector. The image block generator enlarges an image block including a plurality of pixels to generate an enlarged image block. The pixel extractor extracts a maximum pixel with a maximum pixel value and a minimum pixel with a minimum pixel value from the image block. The correction parameter calculator calculates a correction parameter including a first difference and a second difference. The first difference is an absolute value of a difference between a sample pixel value of a sample pixel to be corrected in the enlarged image block and the maximum pixel value. The second difference is an absolute value of a difference between the sample pixel value and the minimum pixel value. The corrector corrects the enlarged image block using the correction parameter.

  • Publication number: 20120133646
    Abstract: According to one embodiment, an image processing apparatus includes a fixed point setting module, a sampling point setting module, and a parallax image generator. The fixed point setting module sets a fixed point to a sampling coordinate space generated from first image data including a first pixel. The sampling point setting module sets a target point to the sampling coordinate space, and sets a sampling point corresponding to the target point to a calculated sampling coordinate. The parallax image generator calculates a pixel value of a second pixel to be located on the sampling coordinate, and generates plural pieces of second image data, each second image data including the second pixel.

  • Patent number: 7819765
    Abstract: An arm (3) supporting a tension pulley (2) around which an endless torque transmitting member (B) is looped is supported by a fixed member (E) via a base member (7). A torsion coil spring (8) is interposed between the base member (7) and the arm (3). The base member (7) is brought into pressure-contact with the fixed member (E) by a tightening force of a bolt (6). A pivot shaft (5) is fitted onto the outer circumference of the bolt (6) so as not to cause a tip to contact the fixed member (E). By transmitting an axial force generated by tightening the bolt (6) to the base member (7) via a flange (5A) formed on the outer circumference of the pivot shaft (5), the distribution of a contact pressure between the fixed member (E) and the base member (7) is optimized.

  • Publication number: 20070065115
    Abstract: A data recording and recomposing method according to one embodiment of the invention includes the following processes. When desired reception data is extracted from one or a plurality of reception data and the extracted reception data is recorded, additional information which represents the data size of the reception data received during a predetermined time interval is recorded. The recorded desired reception data is recomposed while determining the data size to be recomposed per predetermined time interval based on the additional information.
