  • Patent number: 6097270
    Abstract: A coaxial dielectric filter comprising a straight cutoff waveguide, at least two coaxial dielectric resonators disposed coaxially or substantially coaxially and at an interval in the cutoff waveguide in its lengthwise direction, a rod-like input-side antenna whose leading end stands close, or inserted, to the inside of an input-side inner conductor of the coaxial dielectric resonator disposed on the input side, and a rod-like output-side antenna whose leading end stands close, or inserted, to the inside of an output-side inner conductor of the coaxial dielectric resonator disposed on the output side. This filter is characterized in that an adjacent-side end of at least one of coaxial dielectric resonators adjacent to each other forms a slope which is inclined with respect to the cutoff waveguide in its cross section perpendicular to the lengthwise direction.

  • Patent number: 5751112
    Abstract: A magnetic compensating circuit includes a magnetic sensor (1), a control circuit (2) for generating a signal for magnetic compensation, and coils (3) for magnetic compensation. The magnetic sensor has a pair of amorphous magnetic substance wires (101) arranged in parallel, coils (102) for providing the pair of amorphous magnetic substance wires with bias magnetic fields in directions opposite to each other, a high-frequency power source (105) for supplying the pair of amorphous magnetic substance wires with high-frequency currents, and circuits (106, 107, 108, 109) for outputting a potential difference derived from the output of the pair of amorphous magnetic substance wires. Thus, this magnetic compensating circuit is capable of detecting a minute external magnetic field with high accuracy.
