Abstract: PURPOSE:To equalize a magnetic domain to improve sensing accuracy by providing a bias magnet for applying a magnetic field such that an approximate center of a linear region of magnetic field intensity-rate of change in resistance characteristics may be zero in magnetic field intensity distribution with respect to a ferromagnetic thin film. CONSTITUTION:A bias magnet 8 for applying a bias magnetic field to a ferromagnetic thin film 3 is provided. The intensity of the magnet 8 is set at a magnetic field such that an approximate center of a linear region in magnetic field intensity-rate of change in resistance characteristics may be zero in magnetic field intensity distribution. Voltage is applied to a coil 11 by a power source 12 to apply magnetic flux phi to an apparatus 1 and a pressure applied by a pressure applying member 10 is measured by the magnetic field intensity- rate of change in resistance characteristics. As a result curves of the magnetic field intensity-rate of change in resistance characteristics align with each other when the magnetic field intensity is changed from a negative region to a positive region and when it is changed from a positive region to a negative region. Thus a magnetic domain can be equalized so as to improve sensing accuracy.

Abstract: PURPOSE:To attain parallel grid lines when grids are projected on an antenna aperture via a reflection mirror by forming the grids constituting a polarized wave grid plate as lines not in parallel with each other. CONSTITUTION:A curved face polarized wave discriminating grid plate 15 is arranged in opposition to a reflection mirror 1 and a primary radiator 3.

Abstract: PURPOSE:To form a prescribed tape path by drawing out a magnetic tape from a cassette half in accordance with opening and closing movement of a loading mechanism. CONSTITUTION:The closing movement of the half loading mechanism is transmitted via a motive power transmitting mechanism 400 to a slide plate 510, whereas right and left guide rolls 525 and 520 and slant posts 526 and 521 are disposed around a rotary drum 210. A right side pull roller 601 and a left side pull roller 701 are interlocked with the same slide plate 510 via their respective interlocking mechanisms, and are sent into their positions of opening right and left.
