摘要： The image display apparatus includes first and second display elements respectively displaying first and second original images, and an optical system presenting an enlarged combined image of the first and second original images with first and second light fluxes from the first and second display elements. The optical system includes at least one reflective surface. When a cross-section of the optical system on which optical paths of the first and second light fluxes are turned by reflections at the reflective surface is defined as a decentering cross-section, the first and second original images correspond to different view angles in the decentering cross-section. Light flux components respectively included in the first and second light fluxes and introduced to a same image point in the enlarged combined image are overlapped with each other on an exit pupil plane.

摘要： The image observation apparatus includes a first image-forming element and a second image-forming element each of which forms an original image, and an optical system configured to introduce light fluxes from the first and second image-forming elements to an exit pupil position of the optical system where an eye of an observer is placed. The optical system includes an optical surface as a single surface that reflects the light flux from the first image-forming element and transmits the light flux from the second image-forming element. The first image-forming element and the second image-forming element respectively form a first original image and a second original image that correspond to different viewing fields from the exit pupil position. The apparatus combines plural original images to enable observation of one combined image and that can suppress generation of light scattering.

摘要： A fuel supply apparatus for an internal combustion engine includes: a feed pump capable of feeding a fuel of the internal combustion engine; a high pressure fuel pump that pressurizes the fuel fed from the feed pump; and a second injector that supplies the pressurized high-pressure fuel to the internal combustion engine selectively. An ECU of the fuel supply apparatus includes: a pulsation width detection unit that detects a pulsation width in a pressure of the fuel fed from the feed pump to the high pressure fuel pump; and a feeding condition determination unit that determines that a condition variation causing fuel vapor to form in the fuel fed to the high pressure fuel pump has occurred when the pulsation width detected by the pulsation width detection unit falls rapidly to a preset threshold variation width.
