  • Combined capacitive loaded monopole and notch array with slits for multiple resonance and impedance matching pins
    Patent number: 5402136
    Abstract: A conductive layer is formed on one surface of an insulating substrate. Notches are formed in the conductive layer to be axially symmetric at equal angular intervals of 120.degree.. A feeding line of a notch antenna is formed on the other surface of the substrate. The feeding line has a C-shape and wide portions for adjusting the phases of excitation of the notches, and receives power at its one point. A ground plate is arranged to be parallel to the substrate. A feeding rod is connected to the conductive layer. The conductive layer and the ground plate are short-circuited by impedance matching pins. The matching pins are integrally formed with the ground plate. The notches and the feeding line constitute an notch antenna, and the feeding rod, the ground plate, the conductive layer, and the matching pins constitute a capacity loaded monopole antenna. To resonate these antennae at a plurality of resonant points, slits are formed in the conductive layer to be axially symmetric at equal angular intervals of 120.

  • Viscoelastic damper
    Patent number: 4759428
    Abstract: A viscoelastic damper which is adapted to control the vibration of a structural member, a tank, a pipe, etc. which may be caused by an earthquake or wind while producing minimum reaction force when the structural member and so on is slowly displaced as a result of the thermal deformation of the member itself or another member connected thereto. Such a property of a viscoelastic damper can be obtained by using dilatant liquid which presents relatively small resistance when the speed of the motion is small and produces progressively great resistance as the speed of the motion increases. To the end of enhancing this favorable property of the viscoelastic damper, the shoulder surfaces that are exposed to the dilatant liquid are rounded. By providing a spiral groove or projection in the member exposed to the dilatant liquid to produce rotational motion between the two ends of the damper, this property is enhanced even more.
