    • An onboard lamp fixture for a vehicle includes a hollow conical body. The conical body is divided into a top portion having multiple flanges formed on an outer periphery of the top portion and multiple indentations each defined between two adjacent flanges, a middle portion having multiple intermittently formed threads on an outer periphery of the middle portion and annular gaps each defined between two adjacent threads and a bottom portion. After the conical body is extended through a through hole, a bottom face defining the annular gap of each thread is able to engage with an outer periphery defining the through hole and the flanges are able to securely engage with an inner periphery defining the through hole to secure the conical body.
    • 用于车辆的车载灯具包括中空圆锥体。 圆锥体被分成具有形成在顶部的外周上的多个凸缘的顶部部分和分别限定在两个相邻的凸缘之间的多个凹口,在中间部分的外周上具有多个间歇形成的螺纹的中间部分和环形间隙 每个限定在两个相邻的螺纹和底部之间。 在锥形体延伸穿过通孔之后,限定每个螺纹的环形间隙的底面能够与限定通孔的外周接合,并且凸缘能够与限定通孔的内周牢固地接合, 固定锥体。

    • A reflective signal booster for omni-directional antenna is applicable to a tube or flat omni-directional dipole antenna for changing the antenna from an omni-directional type into a directional type, preventing interference of the radiation of the antenna with other equipments, and improving the antenna gain. The signal booster which can be attached easily to an antenna is composed of a reflector formed by two metal plates forming an included angle that is fixed by an angle fixer. The antenna is supported by a supported member and thus properly located between the metal plates. Thus, electromagnetic waves from the antenna and traveling toward the metal plates is blocked and reflected toward a front opening formed between the metal plates whereby signal intensity in a frontward direction is enhanced and interference with equipments located behind the metal plates is eliminated.
    • 用于全向天线的反射信号增强器适用于管或平面全向偶极天线,用于将天线从全向改变为定向型,防止天线与其他设备的辐射干扰,并改善 天线增益。 可以容易地附接到天线的信号增强器由形成由角度定​​影器固定的夹角的两个金属板形成的反射器构成。 天线由支撑的构件支撑,因此适当地位于金属板之间。 因此,来自天线的电磁波向金属板移动,被阻挡并朝着形成在金属板之间的前开口反射,从而增强了向前方向的信号强度,并且消除了位于金属板后面的设备的干扰。
