  • Publication number: 20220190257
    Abstract: A functional film includes an aromatic compound which has a condensed or noncondensed 6-membered aromatic hydrocarbon ring or aromatic heterocyclic ring having four or more condensed aromatic ring groups containing not less than 14? electrons, wherein three or more of the condensed aromatic ring groups containing not less than 14? electrons are adjacent as substituents. For the aromatic compound, a film density value calculated by molecular dynamics calculation of NPT ensemble at 300 K is defined as an initial film density of the functional film comprising only the aromatic compound. For the aromatic compound, when a film density value calculated by molecular dynamics calculation at 370 K is defined as a film density value after storage of the functional film at the temperature, the difference between the initial film density and the film density value after storage is 1% or less with respect to the initial film density.

  • Patent number: 10603241
    Abstract: A controller for a motion assisting apparatus for a wearer includes circuitry. The circuitry is configured to set switching points in a change in a turning angle of a drive mechanism driven by a drive motor and attached to an ankle joint of the wearer to assist a turning motion of the ankle joint, a ratio of the change in the turning angle being equal to zero at the switching points. The circuitry is configured to set a motion pattern such that the turning angle monotonically increases or monotonically decreases between the switching points. The circuitry is configured to control the drive motor to change the turning angle according to the motion pattern.

  • Patent number: 7894691
    Abstract: An article of manufacture is applied to an optical waveguide holding member including a contact surface on the bottom face, which is to be in contact with a printed circuit board; a connection surface on the back face; an optical waveguide connecting the contact surface and the connection surface; and a lens unit disposed at an end of the optical waveguide. A light curing adhesive is applied to a part of the contact surface, adjacent to the lens unit so that the part is bonded to the printed circuit board. A two-component mixed adhesive is applied to, along peripheries of the contact surface in contact with the printed circuit board, outer edges of lateral-side peripheries adjacent to the lens unit and an outer edge of a back-side periphery close to the back face so that the lateral-side peripheries and the back-side periphery are bonded to the printed circuit board.
