  • Publication number: 20200335226
    Abstract: An infection risk map provision system includes virus sensors for detecting viruses in the air, the virus sensors being provided at different positions, a communication unit that collects detection information obtained by the virus sensors, and a control unit that provides, on the basis of the detection information, an infection risk map representing the distribution of infection risk information. The control unit sets display granularity for the infection risk information on the infection risk map displayed on an information terminal on the basis of granularity information corresponding to the virus sensors and creates the infection risk map by superimposing the infection risk information upon a map on the basis of the set display granularity and positional information.

  • Publication number: 20120068368
    Abstract: If an optical lens base having a diffraction grating on the surface is made of a resin, a corrosion reaction is produced between the optical lens base and a nanocomposite film material, thus deteriorating performance as a diffractive optical element. In the manufacturing process of a diffractive optical element according to the present invention, the nanocomposite film material is dripped onto a die and then heated and dried, thereby vaporizing away a solvent from the nanocomposite film material. After that, the dies are assembled to form a nanocomposite film with a predetermined thickness on the optical lens base. As a result, a diffractive optical element with excellent optical properties can be obtained without producing a reaction between the optical lens base and the nanocomposite film material.
