    摘要: An acoustic wave source and a radio wave source are installed close to each other on the ground. When an acoustic wave pulse is transmitted vertically into the atmosphere by the acoustic wave source, spherical wavefronts formed in the atmosphere by the acoustic wave are propagated upwardly at the velocity of sound. When a continuous radio wave is transmitted from the radio wave source toward the spherical wavefronts, it is reflected by the wavefronts and the reflected radio waves are converged to form a focusing spot on the ground. The position where the spot due to the convergence of the reflected radio waves is formed with the maximum intensity is detected by means of an antenna network formed of a multiplicity of receiving antennas laid out in the pattern of a lattice. The time-course change of such positions of the spots is traced to realize remote measurement of the height distribution of wind direction and speed in the atmosphere under surveillance.

    摘要: In a superconducting AC (alternating current) current limiter, quenched trigger coil assembly is quickly recovered to the superconductive state by minimizing a loop current flowing through the trigger coil assembly. The superconducting AC current limiter comprises: a cylindrical core; a superconducting current limiting coil wound on the core, and inserted into an AC power transmission line, for limiting an overcurrent flowing through the AC power transmission line when a failure happens to occur therein; a superconducting trigger coil assembly coaxially wound inside the superconducting current limiting coil on the core, and magnetically coupled to the current limiting coil, for triggering current limiting operation by the current limiting coil when most of the overcurrent flows through the trigger coil assembly, the superconducting trigger coil assembly being arranged by first, second, third and fourth trigger coils in such a manner that the first trigger coil is series-connected to the fourth trigger coil thereby to constitute a first series trigger coil circuit, the second trigger coil is series-connected to the third trigger coil thereby to constitute a second series trigger coil circuit, the first and second series trigger coil circuits are connected in parallel with each other, one end of which is connected to one end of the superconducting current limiting coil and the other end of which is connected via a quenching switch to the other end of the current.

    摘要: An antenna element such as a monopole, dipole or loop antenna is located in the earth or on the floor of the sea so as to receive pre-earthquake electromagnetic waves generated prior to the occurrence of an earthquake. Unwanted noise waves propagating in the air such as man-made noise are effectively eliminated by a reflector laid on the surface of the earth or by the sea water and only the required pre-earthquake waves are detected by the antenna element, whereby earthquakes can be predicted reliably.

    摘要: According to one embodiment, an optical scanning device includes plural light sources, a polygon mirror, a first lens, a first reflection mirror, and a second lens. The polygon mirror deflects lights emitted from the plural light sources in a predetermined direction. The first lens allows the lights emitted from the plural light sources and deflected by the polygon mirror to pass. The first reflection mirror reflects the lights passed through the first lens in a direction different from the deflecting direction of the polygon mirror. The second lens receives incidence of the lights reflected by the first reflection mirror from a direction different from an incident direction of the first lens and allows, with one lens, the lights emitted from the plural light sources to pass.

    摘要: A system for measuring height distributions of atmospheric temperature and wind velocity (wind direction and wind speed) utilizes the facts that a sound wavefront in the atmosphere constitutes part of an ellipsoidal surface and that there always exists a normal which passes through an interior point of the ellipsoid. The Doppler radar is capable of measuring a height distribution of wind velocity on the basis of Doppler frequencies of scattered waves produced by the atmospheric turbulence. The radar and generator are arranged on a straight line in the wind direction so that a radio wave from the radar is directed to the wavefront of a sound wave from the generator. The radar antenna beam is scanned so that it perpendicularly intersects the sound wavefront. The speed of the sound wavefront is measured from the Doppler frequencies of reflected waves. The sound speed is obtained by removing the wind speed component from the measured speed of the sound wavefront. The sound speed obtained is calculated in terms of atmospheric temperature, thereby obtaining the height distribution of the atmospheric temperature.
