摘要： A dielectric substrate 101 is a square substrate having a dielectric constant εr, thickness t and length per side of Wd. A grounding conductor 102 is provided on one side of the dielectric substrate 101 in the same shape as the dielectric substrate 101. An MSA element 103 is formed of square copper foil having a length per side of Wp in the center of the other side of the dielectric substrate 101. Mono-pole antennas 104a to 104d are copper wires having a diameter D and length L and are spaced uniformly on diagonals of the MSA element 103 and disposed perpendicular to the dielectric substrate 101. The MSA element 103 or mono-pole antennas 104a to 104d is selectively fed, whichever has higher reception power. When the mono-pole antennas 104a to 104d are selected, the phases and amplitudes of the respective elements are controlled. This makes it possible to obtain a high gain in all directions over a hemisphere face from the horizontal direction to the vertical direction and provide an antenna apparatus in a small and simple configuration.

摘要： Linear elements 101a to 101d are conductors, which have the element length equivalent to half a wavelength, have been placed so that they may draw a diamond shape. Delay elements 102a and 102b are bent conductors, which have a total length equivalent to one fourth wavelength and a length L2 equivalent to one eighth. The linear elements 101a and 101c are connected one another via the delay element 102a, while the linear elements 101b and 101d are connected one another via the delay element 102b. A feeding section 103 is connected to each of the ends of the linear elements 101a and 101b for feeding power to them. Between the tips of the linear elements 101c and 101d, a gap with a length L3 is left. A reflector 104 has been placed at a distance h from a diamond-shape antenna with delay elements along the −Z axis, the distance h being equivalent to 0.42 wavelength. This achieves the antenna device, which may be suitably mounted on any of small wireless apparatuses and form a primary beam, of which horizontally-polarized wave or vertically-polarized wave tilts toward the horizontal direction.

摘要： A leaf tobacco extract or a concentrate thereof is used as a dispersion medium, which is mixed with powder of a heat-irreversibly coagulating glucan and a dispersion interference-preventing agent including an organic acid. The resultant mixture is stirred to disperse the powder of glucan into the dispersion medium, thereby preparing a slurry having an increased viscosity. This slurry is formed into a sheet, which is then heated and coagulated.

摘要： An EM radiation measuring apparatus. An antenna element matrix (20) on a substrate includes 1st to Lth arrays (4) which are successively arranged in an X direction. Each of the 1st to Lth arrays includes antenna elements arranged in Y direction and having a column output terminal (7), each antenna element receiving an EM radiation from a target and generating a detection signal. A signal selector (5, 3, 2, 7) responsive to X and Y selection signals selectively amplifies and supplies the detection signal from one of antenna elements to one of the column output terminals. 1st to Nth signal outputting circuits selectively couple the column output terminals to provide a single output detection signal. The inputs of the 1st signal outputting circuits are connected to the column output terminals respectively, and each of the 1st to Nth outputting circuits has a transmission line(s) substantially extending in the X direction to connect its output terminals to an input of the next outputting circuit.

摘要： A semiconductor substrate having a silicon-on-insulator structure may achieve superior performance by utilizing a low oxygen content monocrystalline silicon thin film layer for device formation. A supporting substrate, which may comprise a transparent material, such as quartz, or which may be silicon, has an insulating film disposed thereover. The insulating film preferably has a lower diffusion coefficient with respect to impurities than the monocrystalline silicon thin film, which is provided thereover. In accordance with this structure, oxygen particles are not introduced into the monocrystalline thin film and the thin film has a low oxygen concentration to maximize the minority carrier lifetime, enhance device performance characteristics, and prevent the occurrence of latch up.
