  • Patent number: 10510918
    Abstract: An endoscope includes: an imaging device chip having a chip connection portion; a tubular housing tube used to a scope tip portion of an endoscope; a substrate to which the imaging device chip is fixed, the substrate having a substrate connection portion, the substrate being capable of bending at near the substrate connection portion when the substrate is inserted into the housing tube; a lead wire connecting the substrate connection portion and the chip connection portion; flexible and non-conductive resin covering an entirety of the lead wire; and an imaging module including the substrate provided with the imaging device chip thereon, the imaging module inserted into the housing tube.
    Type: Grant

  • Patent number: 6597847
    Abstract: An optical fiber for preserving plane of polarization including a core; and a clad disposed so as to surround the core, wherein the mode field diameter non-circularity ratio of the optical fiber which is calculated according to the equation: MFD ⁢   ⁢ non ⁢ - ⁢ circularity ⁢   ⁢ ratio ⁢   ⁢ ( % ) = Ma - Mb Ma 2 + Mb 2 2 × 100 (where MFD indicates a mode field diameter, and Ma is the maximum value and Mb is the minimum value of the mode field diameter, respectively, in a wavelength region of li
