  • Patent number: 10623618
    Abstract: An imaging device includes an image sensor and an optical system. An imaging surface of the image sensor includes a first region including an intersection with an optical axis and a second region different from the first region. The optical system forms a subject image on the imaging surface so as to cause resolution of the first region to be higher than resolution of the second region. A relationship between a vertical view angle and resolution is different from a relationship between a horizontal view angle and resolution in the subject image.

  • Publication number: 20190273889
    Abstract: An imaging apparatus is attached to a side of a moving body (for example, vehicle). The imaging apparatus includes an image sensor and an optical system that forms a subject image in a range of a predetermined vertical view angle and a predetermined horizontal view angle on an imaging surface. The optical system forms an image on the imaging surface so as to cause resolution in first region (R1) of the imaging surface to be higher than resolution in second region (R2) different from the first region. A position of center (G1) of first region (R1) is at least one of a position horizontally shifted from a center of the horizontal view angle and a position vertically shifted from a center of the vertical view angle.

  • Publication number: 20190072227
    Abstract: A heat insulator is disclosed which simplifies processes of measures for preventing contamination of a surrounding caused by falling off of a silica aerogel in a silica-aerogel support heat insulator. In the silica-aerogel support heat insulator, a support layer whose melting point is lower than a melting point of a fiber supporting the silica aerogel is used, and by performing thermal-pressure bonding at a temperature lower than the melting point of the fiber but higher than the melting point of the support layer to cause the support layer to enter the fiber to combine the support layer and the fiber. Thus, processes of measures for preventing contamination of a surrounding caused by falling off of the silica aerogel can be simplified, and use in a large size and/or in a complicated shape is made possible.

  • Publication number: 20040097592
    Abstract: An object of the present invention is to formulate prostaglandin derivatives which are hardly soluble in water and liable to be adsorbed to a resinous container and prostaglandin derivatives which are liable to decompose when dissolved in water in ophthalmic solutions. Solubility of the prostaglandin derivatives in water is improved and the adsorption thereof to the resinous container can be remarkably inhibited by adding a nonionic surfactant such as polysorbate 80 or polyoxyethylene hydrogenated castor oil 60 to the ophthalmic solutions. The decomposition of the prostaglandin derivatives can be remarkably inhibited by adding an antioxidant such as disodium ethylenediaminetetraacetate or dibutylhydroxytoluene.
