  • Publication number: 20190118716
    Abstract: Crest-valley repeated shapes that are fitted to each other by a biasing force of a spring are disposed so as to be opposed to each other in opposed surfaces that are opposed to each other and rotate relative to each other between a view device base side and a view device rotating section side. Respective height maintaining protrusions are disposed so as to be opposed to each other in the opposed surfaces. Upon the view device rotating section being rotated from an extended position toward a forward-tilted position by an external force, respective top surfaces of the height maintaining protrusions are brought into abutment with and slide on each other in a position in which abutment between respective top surfaces of the crests of the crest-valley repeated shapes is cancelled, to maintain a height of the view device rotating section.

  • Patent number: 10259393
    Abstract: Provided is a mirror display device including a monitor display element for emitting image light vibrating in a first direction in an image display state; and a mirror optical element provided on the display surface side relative to the monitor display element. The mirror optical element can switch reflective and transmissible states. The reflective state is that light vibrating in a first direction from an absorption-type polarization plate side is converted to vibrate in a second direction by a liquid crystal cell to be reflected by a reflection-type polarization plate, and converted to vibrate in the first direction by the liquid crystal cell to be emitted from the absorption-type polarization plate. The transmissible state is that light vibrating in the first direction from a reflection-type polarization plate side is transmitted through the cell as it is, to be emitted from the absorption-type polarization plate.

  • Patent number: 10246017
    Abstract: This invention relates to a view angle adjustment mechanism. A view element tilting section is tiltably supported by the tilting support section. Upon a motor being driven, a nut member rotates together with a gear member, the nut member rises/falls along a male thread member, whereby the view element tilting section is tilted. At a barrel of the nut member, a protrusion is formed. The protrusion is fitted in a groove of the gear member and causes the nut member to rotate together with the gear member. At the tilting support section, a protrusion abutment portion is formed. When the nut member moves in a direction in which the nut member comes off from the male thread member, the protrusion abutment portion abuts on the protrusion and thereby prevents movement of the nut member.

  • Patent number: 10133068
    Abstract: This invention relates to a cold mirror for a head-up display apparatus and provides a cold mirror that enables suppression of a phenomenon of change in color tone of an image depending on a position from which the image is viewed. This invention also provides a head-up display apparatus including the cold mirror. In a head-up display apparatus, display light of an image displayed on a display is reflected by a cold mirror and a reflected image of the image is viewed by a viewer. A relationship between an incident wavelength and a reflection phase difference in the cold mirror is set so that the reflection phase difference falls within a range of 180±60 degrees for an entire visible wavelength range of 420 to 680 nm.

  • Publication number: 20180326717
    Abstract: A printing object surface has a cross-sectional shape curving along a printing advancing direction. The printing advancing direction is defined as a Y-axis, a direction orthogonal to the Y-axis and belonging to the cross-section is defined as a Z-axis, and a direction around an axis orthogonal to a Y-Z plane is defined as a ?-axis. A squeegee is disposed so as to be movable in the respective Y-, Z- and ?-axis directions. Information indicating a mutual relationship among respective Y-, Z- and ?-axis positions is obtained. The relationship is a relationship that enables performing printing while maintaining or substantially maintaining an angle formed by a direction tangent to a printing position in the printing object surface in the Y-Z plane and the squeegee. Printing is executed while the respective Y-, Z-, ?-axis positions of the squeegee relative to the printing object surface are controlled according to the obtained information.

  • Patent number: 10118555
    Abstract: This invention provides a lamp-equipped vehicle outer mirror in which a phenomenon is less likely to occur, the phenomenon being the one in which light emitted from a lamp appears in a light emission pattern that is different from that intended by a designer. A side turn signal lamp is incorporated in a minor housing. A downward inclined surface is formed at a position above a lens of the side turn signal lamp in the mirror housing. The downward inclined surface is inclined obliquely downward and is lustrous. A part of turn signal lamp light emitted from the lens to an external field is reflected by the downward inclined surface. A relative positional relationship between the lens and the downward inclined surface is set so that the reflected light passes through an area on an upper side relative to a horizontal direction.
