Abstract: A compact lens antenna assembly A which is a Luneberg lens antenna comprising a hemispherical lens and a reflecting plate so as to converge incoming radio waves on a feed, and which can receive radio waves from not only a geostationary satellite or an orbiting satellite with high gain even if the incidence angle of the incoming radio waves is large includes lens antenna body 10 including a base plate 11, a reflecting plate 13 and a hemispherical lens 14 made by laminating dielectric materials. The plate 13 and the lens 14 are rotatably mounted on the base plate 11. The antenna body further includes feeds 16a and 16b that can be moved to a desired position along guide rails 15. The antenna assembly further includes a reflecting plate support means 20 mounted on a base 21 and capable of inclining the reflecting plate 13 in a desired direction. By inclining the reflecting plate 13, the incidence angle of radio waves from the satellite is adjustable to a value within a predetermined range.

Abstract: A small, lightweight radio wave lens antenna device is proposed in which freedom of selection of the installation place is high, which can be compactly installed e.g. on a wall surface, and in which restriction of installation space is relaxed. A hemispherical Luneberg lens 2 is mounted on a reflecting plate 1, antenna elements 4 are supported by a retainer 3, they are integrally combined, and a mounting portion 5 is provided for mounting the reflecting plate 1 to a installation portion such as a wall surface with the reflecting plate 1 substantially vertical. The reflecting plate 1 may have such a shape that an area other than the area for reflecting radio waves from directions in a predetermined range is removed, preferably in the shape of a fan. The hemispherical Luneberg lens 2 is mounted on the reflecting plate 1, offset toward the small arcuate edge 1b of the fan.

Abstract: A method and an apparatus for producing an adhesive tape are disclosed in which an adhesive tape is produced while a liquid reservoir is almost hermetically sealed by bringing a blade into contact with an upper laminate roller, and supplement of adhesive to the liquid reservoir is controlled so that the liquid surface of the adhesive reserved in the liquid reservoir comes into contact with the back face of the blade.

Abstract: Exhaust gas amitted from a diesel engine flows through a ceramic soot filter in which particles contained in the exhaust are deposited and oxidized to regenerate the filter. The filter is regenerated by non-thermal, electric surface creeping discharge on filter surfaces covered with particles. In addition, nitrogen oxides may be reduced by selective catalytic reduction. The system is designed to ensure operation reliability and environmental compatibility.

Abstract: It is an object of the present invention to provide a dielectric resin foam which has high and uniform dielectric properties and is preferable for use as various dielectric materials. A dielectric resin foam obtained by expanding a resin composition comprising a synthetic resin and a fibrous and/or plate-like dielectric inorganic filler is provided.
