Filed: 1984-05-22
Abstract: PURPOSE:To improve the working process and durability, by varying the relative resistance of the transparent conducting film with a specified distribution in the longitudinal direction of the fluorescent lamp, and also by making the fluorescent film contain alpha-alumina. CONSTITUTION:The resistance of NESA film of the central part of the fluorescent lamp tube which occupies 3/4 of the whole length of the tube is set between 10-50kOMEGA/cm<2>, and the resistance of the NESA film of the end parts of the tube is set at a higher value than that of the central part. Then, alpha-alumina is added to the fluorescent material. A value more than 10kOMEGA/cm<2> is selected for the resistance of the film of the tube ends even when it is at minimum. Consequently, the range of the resistance value of the transparent conducting film is enlarged, and it can be selected from the range which has little effect on the characteristics of the fluorescent tube. Thus, the variation of the characteristics of the fluorescent lamp is reduced and manufacture of the fluorescent lamp is facilitated.

Abstract: PURPOSE:To measure the bearing of an antenna system from the true north highly precisely by obtaining many angular informations with the aid of the interference phenomenon of GPS signals generated in a pair of antenna systems and, at the same time, using the calculated value concerning the direction of a satellite and its elevation and the known interval distance between the antennas. CONSTITUTION:In an antenna system 1', the antenna element In and Is crosses an antenna system 1 at a right angle and they are placed in an interval of several wavelengths against a GPS signal. A 180 deg. hybrid circuit 2' sends a sum/difference signal of the output from the elements In and Is to GPS receivers 3n and 3n in the same way as a circuit does. The receivers 3n and 3s output digital signals representing its own position, direction and elevation of respective satellites, and signal level through the sum/difference signals from a plurality of satellites and outputs them in the same way as receivers 3e and 3w do. A digital computer 4 calculates the arctangent of the ratio of signal level values, divides the calculated values of the antenna system 1 by the said calculated values, and detects the directions of the respective satellite against the antenna system 1' through applying arctangent calculation. Furthermore, the detected values are calculated to remove the uncertainty therefrom, thereby detecting the antenna bearing from the true north.

Filed: 1992-03-27
Abstract: PURPOSE:To improve characteristics related to critical current density by making the thickness of a superconducting section less than magnetic field invasion depth, and specifying the breadth of the section. CONSTITUTION:A metal or oxide superconductor is used for a superconducting wire 1, and so constituted as to include a section where superconducting current flows until electron or hall pair condensed energy is partially fractured by electron kinetic energy. In other words, the thickness of the superconducting section is made less than magnetic field invasion depth, and the breadth of the section is made approximately equal to or less than twice the depth of magnetic field invasion due to a widthwise magnetic field component, thereby causing superconducting current to flow up to the thermodynamic fracture limit of an electron or a hall pair. Furthermore, a plurality of superconducting sections 2 are buried in a non-superconducting base material in the form of a grating. According to this construction, counter current several ten times as much as current via conventional pinning can be made to flow.
