  • Patent number: 10802289
    Abstract: A virtual image display device has a light guide device in which the half mirror layer (the semi-transmissive reflecting film) of the light guide member is formed on the partial area of the first junction surface, and the second junction surface of the light transmitting member is bonded to the first junction surface in at least the exceptional area. Therefore, it is possible to increase the bonding strength of the first junction surface and the second junction surface, namely the strength of the light guide device composed of the light guide member and the light transmitting member combined with each other even in the case in which the attachment force of the half mirror layer (the semi-transmissive reflecting film) with respect to the first junction surface is not sufficiently strong.

  • Patent number: 10781928
    Abstract: A critical state is assumed in which a position of one end of the opening of the input port in the axial direction and a position of the other end of the groove in the axial direction accord with each other with respect to the axial direction. In the critical state, when a straight line is extended in the axial direction as well as radially outward of the spool without changing a direction of the straight line in a circumferential direction of the spool from one end of the groove bottom in the axial direction with the same inclination as the inclination of the groove bottom at the one end of the groove in the axial direction relative to the axial direction, the straight line passes through the opening of the output port to contact a wall surface of the output port.

  • Patent number: 10735701
    Abstract: In a projection system, a nonaxisymmetric aspheric surface is used as a surface that is located in a position where in a pencil of light of video image light that exits from each of two points in different corner regions in an image plane that is a light exiting plane of an image display apparatus, light components that should reach a viewer's eyes do not intersect one another, whereby the size of an optical system can be further reduced and the size of an overall apparatus can therefore be reduced with a variety of types of optical precision, such as the resolution and angle of view, maintained.
