  • Publication number: 20190318960
    Abstract: A method of forming via openings that includes forming sidewall spacers on a plurality of mandrels that are overlying a hardmask layer that is present on an interlevel dielectric layer. Etching the hardmask layer using a portion of the sidewall spacers and the plurality of mandrels to form a first pillar of hardmask material. The interlevel dielectric layer is etched using the first pillar of hardmask material as a mask to define a first via opening. The plurality of mandrels are removed. The hardmask layer is etched using the spacers to define a second pillar of hardmask material. The interlevel dielectric layer is etched using the second pillar of hardmask material to provide a second via opening.

  • Publication number: 20070028619
    Abstract: A fuel injector for a gas turbine engine has a swirl slot that supplies fuel to a prefilmer. The swirl slot has an upstream lip and a downstream lip that are arranged eccentrically. The slot is thus provided with an area of high static pressure and an area of low static pressure caused by the flowing over the eccentrically arranged lips.

  • Patent number: 4056827
    Abstract: An optical display system for a craft navigation simulator providing a wide angle display of greater than 3:1 width/height format derived from a closed circuit television camera viewing a terrain model. A wide-angle scene viewed is divided into three or more parts at vertical boundaries all of which are off-center and folded by a first optical system into substantially square format, in which format the composite image is processed from camera tube to display tube. A second optical system reconstructs the original wide angle image. By this means, high definition of the image in the center region and, particularly, near the horizon, is maintained.

  • Patent number: 4048653
    Abstract: Head-coupled visual display apparatus for a sole observer, particularly in craft flight simulation apparatus, for providing to a pilot a view simulating that seen from an actual craft. The apparatus includes an image generator of known type, such as closed circuit television or computer generated image types, an image projector, a helmet with a binocular viewer attached and a movable optical path linking the image projector with the helmet viewer. The helmet binocular viewer comprises a beam-splitter, which splits the image beam into left-eye and right-eye beams, and left-eye and right-eye mirrors, which reflect the corresponding image beams onto a retro-reflective screen, and which permit the pilot to view the cockpit and the reflected image therethrough. Sensing means detect head movements of the pilot and the generated image is changed correspondingly, to permit voluntary scanning of a wide angle field of simulated view.

  • Patent number: 3932702
    Abstract: An optical display system, particularly for providing the visual display of terrain overflown to the trainee crew of a flight simulator, and including an optical probe, closed-circuit television system and projection monitor providing a visual display scene upon a projection screen viewed by trainee crew, in which the displayed scene and the scene viewed by the probe are wide-angle and optical means are included to dissect the image into two parts, without image reduction on either axis, and to reassemble the image parts into a composite image of substantially square format, for transmission and reproduction by the television system, further optical means being used to rearrange the composite image parts to reproduce the original wide-angle scene.Image-splitting prism devices are used to provide the square format and to reproduce the wide-angle format.
