There is provided an optical device for transferring light within a given field-of-view, comprising an input aperture; reflecting surfaces, and an output aperture located in spaced-apart relationship from the input aperture such that light waves, located within the field-of-view, that enter the optical device through the input aperture, exit the optical device through the output aperture, wherein the reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of the light waves located within the field-of-view that enter the input aperture, pass directly to the output aperture without being reflected off the at least one pair of parallel reflecting surfaces, while another part of the light waves within the field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by the at least one pair of parallel reflecting surfaces.

A system and process are disclosed for the controlled combustion of a wide variety of hydrocarbon feedstocks to produce thermal energy, liquid fuels, and other valuable products with little or no emissions. The hydrocarbon feeds, such as coal and biomass, are first gasified and then oxidized in a two-chamber system / process using pure oxygen rather than ambient air. A portion of the intermediate gases generated in the system / process are sent to a Fischer-Tropsch synthesis process for conversion into diesel fuel and other desired liquid hydrocarbons. The remaining intermediate gases are circulated and recycled through each of the gasification / oxidation chambers in order to maximize energy production. The energy produced through the system / process is used to generate steam and produce power through conventional steam turbine technology. In addition to the release of heat energy, the hydrocarbon fuels are oxidized to the pure product compounds of water and carbon dioxide, which are subsequently purified and marketed. The system / process minimizes environmental emissions.

In a process for producing an aromatic carboxylic acid, it is a dehydrating process which can achieve compactification of a step for removing water from a mixture of acetic acid and water produced in the production process, and which can reduce the consumed energy. In a production process of an aromatic carboxylic acid having an oxidation reaction step for producing a slurry of an aromatic carboxylic acid by carrying out liquid-phase oxidation reaction of an alkyl aromatic compound with an oxygen-containing gas in a solvent containing acetic acid in the presence of an oxidation catalyst, at least a portion of a mixture containing acetic acid and water produced in the production steps is separated into a permeable gas mainly comprising water and nonpermeable substances mainly comprising acetic acid, using a separation membrane having water selectivity.

Embodiments of the portable antenna positioner described provide a lightweight, collapsible and rugged antenna positioner for use in receiving low earth orbit, geostationary and geosynchronous satellite transmissions. By collapsing the antenna positioner, it may be readily carried by one person or shipped in a compact container. The antenna positioner may be used in remote locations with simple or automated setup and orientation. In order to operate the apparatus, azimuth is adjusted by rotating an antenna in relation to a positioner base and elevation is adjusted by rotating an elevation motor coupled with the antenna. The apparatus may update ephemeris data via satellite, may comprise a built-in receiver and may couple with a second positioner base comprising cryptographic, router or power functionality. The apparatus may comprise storage devices such as a hard drive or flash disk for storing data to and from at least one satellite.

A semiconductor integrated circuit having a built-in A / D conversion circuit which enables, where the A / D conversion circuit is to be built into a semiconductor chip, the required capacitance of the stabilization capacitor to be connected to the output terminals of reference voltage generators for generating reference voltages to be reduced is to be provided to contribute to preventing the number of external terminals and the chip size from increasing. A semiconductor integrated circuit having a built-in differential type A / D conversion circuit comprising a differential amplifier, a local A / D converter and local D / A converters, further provided with a first reference voltage generator for generating a first reference voltage and a second reference voltage generator for generating a second reference voltage both for use by the local A / D converter, wherein the first reference voltage generator and the second reference voltage generator are provided as common reference voltage generators with a reference voltage generator for generating a first reference voltage and a second reference voltage both for use by the local D / A converters, and a capacitance element for stabilizing the generated reference voltages is connected between the output terminal of the first reference voltage generator and that of the second reference voltage generator.

A sequential color display system using a white light source to create a full color image projected onto an image plane. A dynamic filter, typically a series of moving dichroic filters, generates a series of primary colored light beams that are swept across the surface of a spatial light modulator. Typically all three primary colors are produced simultaneously by the dynamic filter. The illuminated portion of the dynamic filter is imaged onto the modulator and controller provides appropriate image data for each portion of the modulator in synchronization with the sweep of the primary color bands across the modulator surface. The primary color bands are modulated by the spatial light modulator and the modulated light is focused by lens onto the image plane. The viewer integrates the light arriving at each portion of the image plane over a frame period to provide the perception of a full-color image.
