  • Publication number: 20080174508
    Abstract: An array antenna apparatus includes a first feeding element having a first feed point, a second feeding element having a second feed point, and a first parasitic element electrically connected to the respective first and second feeding elements. In a first frequency band, respective resonances in the feeding elements occur independent of each other, by eliminating electromagnetic mutual coupling between the feeding elements, and exciting the first feeding element through the first feed point as well as exciting the second feeding element through the second feed point. In a second frequency band lower than the first frequency band, a loop antenna having a certain electrical length is formed by the first and second feeding elements and the first parasitic element, and a resonance of the loop antenna substantially occurs by exciting the first feeding element through the first feed point.

  • Publication number: 20070054062
    Abstract: In the application of plasma spraying to a metal body, it is intended to attain reduction of spraying cost and improvement of working efficiency in roughening operation while maintaining anticorrosive effects. An adhesion strength of spray coating comparable to that obtained in the conventional combination of blast treatment and gas flame spraying can be realized even if roughening is conducted with the use of simple tools by performing in advance such a roughening treatment that the average roughness (Ra) of surface of thermal spray subject falls within the range of 2 to 10 ?m with the use of a grinding tool and thereafter carrying out thermal spraying under such conditions that the average area of each of molten particles when molten particles of a thermal spray material have stuck to the surface of thermal spray subject falls within the range of 10000 to 100000 ?m2.
