  • Publication number: 20200377005
    Abstract: A vehicle light-adjusting system includes a light-adjusting member arranged in an incident portion into which an external light enters, a control unit that controls transmittance of the light-adjusting member, and an instruction detecting unit. The light-adjusting member is divided into a plurality of parts. The instruction detecting unit detects an instruction given by the occupant in a non-contact manner to the light-adjusting member by at least one of gesture and words. When the instruction detecting unit detects the instruction designating any one of the parts, the control unit adjusts an individual transmittance of the part corresponding to the instruction detected by the instruction detecting unit.

  • Publication number: 20200376937
    Abstract: The light-adjusting system includes an interior sensor that detects interior data for grasping a state of an interior of the vehicle, an interior information acquiring unit that acquires information related to the state of the interior based on the interior data detected by the interior sensor, a determination unit that determines whether or not the interior is in an abnormal state based on the information acquired by the interior information acquiring unit, and an adjustment unit that adjusts the light transmittance of the window glass. When it is determined as the abnormal state where the light transmittance of the window glass has been adjusted such that it is difficult to visually recognize the interior through the window glass, the adjustment unit adjusts the light transmittance of the window glass to visually recognize the interior from outside the vehicle through the window glass.

  • Publication number: 20200377014
    Abstract: A vehicle light-adjusting system capable of adjusting the brightness in a vehicle interior day and night and appropriately performing light-adjustment for each of occupants. The vehicle light-adjusting system includes an incident portion which external light enters, a light-adjusting member arranged in the incident portion, a light emitting unit provided in an interior of the vehicle, and a control unit. The control unit controls transmittance of the light-adjusting member and controls illuminance of the light emitting unit. The light-adjusting member is divided into a plurality of parts. The control unit is capable of adjusting an individual transmittance of each of the parts.

  • Patent number: 10808087
    Abstract: A fiber composite material includes mixed fibers including a plant fiber and an ultrahigh-strength elongation fiber and thermoplastic resin that binds the mixed fibers each other. The ultrahigh-strength elongation fiber has tensile modulus that is 4000 MPa or greater and is greater than tensile modulus of the thermoplastic resin and has tensile elongation at break that is greater than tensile elongation at break of the plant fiber.

  • Patent number: 10625478
    Abstract: A method of manufacturing a reinforcement layer comprises a preparatory step of preparing to-be-wound fiber, and a formation step of forming an uncured sheet layer including multiple layers of the to-be-wound fiber stacked on an outer circumferential surface. In the formation step, the to-be-wound fiber is wound on the outer circumferential surface in such a manner that, regarding an outer layer of the uncured sheet layer and an inner layer of the uncured sheet layer closer to the outer circumferential surface than the outer layer and adjacent to the outer layer in a stacking direction of the to-be-wound fiber, two end portions of the outer layer are located between two end portions of the inner layer in an axis direction extending along a center axis of a winding target member.

  • Publication number: 20170241591
    Abstract: A high-pressure tank which is capable of improving the strength of a connecting part between a cylindrical part and a dome part is provided. A high-pressure tank 10 according to the present invention comprises: a liner 20 having a cylindrically-shaped cylindrical part 20a and hemispherically-shaped dome parts 20b which are continuous with both ends of the cylindrical part 20a; and a reinforcing layer 30 including a fiber bundle which is hoop-wound around the cylindrical part 20a of the liner 20 and a fiber bundle which is helically wound around the dome parts 20b thereof. An outer diameter of the end of the cylindrical part 20a is smaller than an outer diameter of a portion of the cylindrical part 20a which excludes the end.
