    • There is provided a method for designing a corrugated Fermi antenna having a broad-band and circular directivity required for receiving an image by using a wave of millimeter order. As a first step, an inflection point of the Fermi-Dirac function as a taper function of the Fermi antenna is changed so as to set the beam width of plane H to a beam width having a target directivity. After the beam width of the plane H is set to the target value, the aperture width of the Fermi antenna is changed so as to set the beam width of the plane E to a beam width having a target directivity. Thus, by adjusting the beam width values of the planes H and E independently from each other and matching them with the target values, it is possible to design a Fermi-antenna having a broad-band and circular directivity in a short time.
    • 提供了一种用于设计波纹费米天线的方法,其具有通过使用毫米级波来接收图像所需的宽带和圆形方向性。 作为第一步骤,改变费米 - 狄拉克函数作为费米天线的锥度函数的拐点,以将平面H的波束宽度设置为具有目标方向性的波束宽度。 在将平面H的波束宽度设定为目标值之后,改变费米天线的孔径宽度,以将平面E的波束宽度设定为具有目标方向性的波束宽度。 因此,通过彼此独立地调整平面H和E的波束宽度值并将其与目标值相匹配,可以在短时间内设计具有宽带和圆形方向性的费米天线。

    • A hinge structure of a spectacle frame has bearings formed at the ends of end pieces provided outside a pair of lenses or outside the rims supporting the lenses, pivotally rotatable shafts at the tips of a pair of temples are pivotally rotatably connected with the bearings, a compressed elastic means, being provided around the pivotally rotatable shaft exposed in the recess between the flange and the support face, to give pressure to the bearing for keeping the sliding face of the temple in slidable contact with the sliding face of the bearing. The hinge structure of a spectacle frame overcomes the disadvantages of the conventional hinge structure; that is functionally excellent because of easy assembling, needlessness of complicated adjustment, and capability to keep the temple turning torque constant for a long time; and that is also excellent in appearance and design.
    • 眼镜架的铰链结构具有形成在设置在一对透镜外侧的端部的端部处或支撑透镜的边缘外侧的轴承,在一对镜腿的顶端处的可转动的轴可与轴承可转动地连接, 压缩的弹性装置设置在暴露在凸缘和支撑面之间的凹部中的可枢转转动的轴周围,以向轴承施加压力,以将镜腿的滑动面保持与轴承的滑动面滑动接触。 眼镜架的铰链结构克服了常规铰链结构的缺点; 由于组装容易,调整不必要,长时间保持镜腿转矩恒定的能力,功能上优异; 而且在外观和设计上也很出色。
