Abstract: A main object of the present invention is to provide a cell transfer substrate capable of transplanting cells, maintaining a pattern as it is, on a living body tissue or the like, even when: the size of the cell sheet is extremely small; the cells are cultured sparsely; the cells are in a form of a small colony; or the cells are cultured in a pattern, for example, as a blood vessel, a vessel network such as a lymphatic vessel, or a nerve network, and to provide a substrate for cell transfer to be used for the cell transfer substrate. In order to achieve the above-mentioned object, the present invention provides a substrate for cell transfer comprising: a polymer base material; an intermediate layer formed on the polymer base material; and a cell transfer layer formed on the intermediate layer.

Abstract: Lens antenna equipment including a hemispherical Luneberg lens made of dielectric, a reflector which has a size larger than the lens diameter and which is to be provided on a face equivalent to a cross-section made by halving a globular shape of the lens, a primary feed to be arranged at a focus part of the lens, and an arm for holding the primary feed, all of which are unitarily assembled together, wherein the holder of the arm can be turned about an axis that is a perpendicular line passing the center of the lens when the reflector is attached to its installation position in a substantially perpendicular manner with respect to the ground surface, and wherein the primary feed can be moved along the surface of the lens, on a plane that is perpendicular to the axis passing the center of the lens, and on a semicircle centering the axis.

Abstract: A Luneberg lens having a single-layer structure or a multilayer structure containing a plurality of layers having different dielectric constants, wherein the respective structure is produced by mixing a polyolefin resin and/or a derivative thereof with an inorganic filler having a high dielectric constant, the volume ratio of the polyolefin resin and/or the derivative thereof to the filler being 99 to 50:1 to 50, adding a foaming agent to the resulting resin mixture and then performing preliminary expansion, and molding the resulting pre-expanded beads; and wherein at least a foamed dielectric layer having a dielectric constant of 1.5 or more is formed using the pre-expanded beads that have been subjected to classification and selection such that f(A) satisfies the expression 0.0005?f(A)?0.

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 multi-beam lens antenna for individual communication with communication satellites spaced at small elongations. The multi-beam antenna comprises primary feeds 3 each of which is composed of a waveguide having an opening at the end and a dielectric body 6 disposed at the end, a hemispherical Luneberg radio wave lens, and a reflective plate attached to the circular opening of the hemispherical radio wave lens and adapted for reflecting a radio wave incoming from the sky or emitted toward a target. The waveguides are preferably rectangular waveguides 4 rather than circular waveguides 5. The dielectric bodies 6 are preferably tapered.

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.
