    Abstract: In an antenna for communicating an electromagnetic wave, a first converger converges the electromagnetic wave. A second converger faces the first converger and includes a conductor plate having a through hole, into which a magnetic flux of the converged electromagnetic wave is converged. The through hole is formed at a center portion of the conductor plate so as to have a size which is sufficiently smaller than a wavelength of the electromagnetic wave. The conductor plate is formed with a cutout extending from a part of the through hole to an outer periphery of the conductor plate. A converter faces the through hole of the conductor plate to convert the converged magnetic flux into voltage.

    Abstract: To obtain stable linear torque-output characteristics over a wide torque range in a magnetostrictive torque detecting apparatus having a shaft to be measured, an exciting coil for magnetically exciting the shaft, and a detecting coil for detecting magnetostrictive components generated in the shaft distorted by a torque, the shaft is particularly composed of a substrate shaft portion made of a high yield point material and a shape anisotropic layer portion made of a high magnetostrictive material metallographically welded on an outer surface of the substrate shaft. The welded shape anisotropic layer portion is formed with two symmetrical groups of concave/convex portions each arranged at regular angular intervals on the outer circumferential surface thereof at an inclination angle with respect to the axial direction of the shaft.

    Abstract: The present invention provides an elevator system for transferring a large number of passengers at a high speed and for operating elevators to stop at each floor or as an express for passing floors. An ascending passage and a descending passage are sectionally formed in an elevator shaft having an upper turning portion, a fixed portion and a lower turning portion, respectively. Both the ascending and descending shafts are provided with a local line, a passing line and a sliding area. Switch frames for switching the line and the area are provided at a plurality of locations and a linear motor drive mechanism is provided on the cages and a center core of the elevator shaft.
