  • Patent number: 11584835
    Abstract: A laminated substrate obtained by laminating a carbon fiber reinforced resin substrate (a) containing a carbon fiber and a thermoplastic resin fiber and a glass fiber reinforced resin substrate (B) containing a glass fiber and a thermoplastic resin, wherein a content of the carbon fiber in the carbon fiber reinforced resin substrate (a) is 20% by mass or more and less than 100% by mass with respect to a total mass of the carbon fiber reinforced resin substrate (a), and the carbon fiber reinforced resin substrate (a) has an elongation percentage of from 20% to 150% at a maximum load point in a MD direction at a temperature of a melting point of a resin constituting the thermoplastic resin fiber+20° C., an elongation percentage of from 20% to 150% at a maximum load point in a TD direction, and a tensile stress of 1.0×10?3 to 1.0×10?1 MPa.

  • Patent number: 7171088
    Abstract: A number of optical fiber cords 11 are bundled together to constitute an image fiber. A first end of the image fiber 12a is incorporated within and covered by a cylindrical member to constitute an imaging section, which in turn forms one of a plurality of imaging sections. The second end of the image fiber is incorporated within a fiber bundling unit so that an image pickup device simultaneously read images captured by the plurality of imaging sections and transmitted to the image pickup device via optical means. Within the fiber bundling unit a plurality of cylindrical holes are provided, in an orderly fashion and in a lattice pattern, and into at least one cylindrical hole one end of the image fiber that forms an imaging section is inserted. All of the end faces of a plurality of image fibers are aligned in the same plane to thereby form a flattened surface.

  • Patent number: 6694254
    Abstract: A map display includes a display screen for displaying read map image data, an input for designating an absolute position obtained by a positioning device on a map displayed by the display screen, and a controller for calculating positions on the map corresponding to the absolute positions obtained by the positioning device based on the absolute positions of at least two points on the map designated by the input and for displaying the calculated positions on the map displayed on the display screen.

  • Publication number: 20030103744
    Abstract: A number of optical fiber cords 11 are bundled together to constitute an image fiber 12a. One end of the image fiber 12a is incorporated within and covered by a cylindrical member 14 to constitute an imaging section 15a, which in turn constitutes one of a plurality of imaging sections. The other end of the image fiber 12a is incorporated within a fiber bundling unit 16 so that an image pickup device is able to simultaneously read images captured by the plurality of imaging sections and transmitted via optical means. In the fiber bundling unit 16 are provided a plurality of cylindrical holes 17 including a cylindrical hole 17a in an orderly fashion and in a lattice pattern, and into the cylindrical hole 17a is inserted one end of the image fiber 12a that constitutes the imaging section 15a. At the same time, all of the end faces of a plurality of image fibers including the image fiber 12a are aligned in the same plane to thereby form a flattened surface.

  • Publication number: 20030078725
    Abstract: A map display includes a display means for displaying read map image data, an input means for designating an absolute position obtained by positioning by a positioning means on a map displayed on the display means, and a control means for calculating positions on the map corresponding to the absolute positions obtained by positioning by the positioning means based on the absolute positions of at least two points on the map designated by the input means and for displaying the calculated positions on the map displayed by the display means.
