  • Patent number: 10678017
    Abstract: A projection type image display device includes an oblique projection optical system that magnifies and projects modulated image light, and includes lens elements and a reflection mirror having a convex surface. A center of an outer shape of one or more of the lens elements at a nearest position to the reflection mirror is positioned above an optical axis. The reflection mirror has a reflection surface shape orthogonal to a projection plane inclusive of the optical axis of the reflection mirror. The reflection surface shape and lens element are formed as specified. For example, the reflection surface shape is formed so that an average radius of curvature in an area through which a light flux focused at a center of the projection plane passes is smaller than that of curvature in an area through which a light flux focused at an upper end portion of the projection plane passes.

  • Publication number: 20190390320
    Abstract: A pre-drying processing liquid containing a sublimable substance that changes to gas without passing through to a liquid and a solvent in which the sublimable substance dissolves is supplied to a front surface of a substrate on which a pattern has been formed. Thereafter, the solvent is evaporated from the pre-drying processing liquid on the front surface of the substrate to thereby form a solidified body containing the sublimable substance on the front surface of the substrate. Thereafter, the solidified body is sublimated and thereby removed from the front surface of the substrate. A value acquired by multiplying a ratio of the thickness of the solidified body to the height of the pattern by 100 is greater than 76 and less than 219.
