    • This invention discloses an improved construction for portable disk antenna. This construction mainly comprises a disk antenna body, an outer member, an inner member, and a base. The outer member may rotate over 360 degrees about a first axis relative to the base. The inner member is rotably fitted into the outer member. The disk antenna body is connected to the inner member such that the disk antenna body, together with the inner member, can be rotated with respect to the outer member within an appropriate angular range about a second axis perpendicular to the first axis. This invention is characterized by further comprising an azimuth calibrating device having an azimuth calibration scale formed thereon for calibrating the azimuth deviation of the disk antenna body before use according to the indication of a compass; and an elevation calibrating device having an elevation scale formed thereon for calibrating the elevation deviation of the disk antenna body according to the indication of a level instrument. Consequently, the user can complete deviation calibration of the azimuth and the elevation of the disk antenna body by simple operation before use, and then directly adjust the azimuth and the elevation of the disk antenna body to correct values according to the operation manual for the portable disk antenna in order to readily receive the expected signals from the target artificial satellites.
    • 本发明公开了一种便携式盘式天线的改进结构。 该结构主要包括盘状天线体,外部构件,内部构件和底座。 外部构件可相对于基座围绕第一轴线旋转360度以上。 内部构件可旋转地装配到外部构件中。 圆盘天线体连接到内部构件,使得盘状天线体与内部构件一起可以在垂直于第一轴线的第二轴线的适当角度范围内相对于外部构件旋转。 本发明的特征还在于包括:方位校准装置,其具有形成在其上的方位校准标尺,用于根据指南针的指示校准盘天线体在使用前的方位偏差; 以及其上形成有仰角的仰角校准装置,用于根据水平仪器的指示来校准盘状天线体的仰角偏差。 因此,用户可以在使用前通过简单的操作完成圆盘天线体的方位角和仰角的偏差校准,然后根据便携式的操作手册直接调整圆盘天线体的方位角和仰角,以校正值 以便容易地从目标人造卫星接收预期信号。

    • A hygienic exercise equipment includes thermo plastic elastomer having a composition comprising bamboo charcoal powder, PVC, ZN-CA stabilizer, pour point depressant, ink and at least one of DOP and ATBC. Preferably, bamboo charcoal from 0.1% to 5%, PVC from 35% to 56%, ZN-CA stabilizer from 0.4% to 1.5%, pour point depressant from 0.5% to 1.5%, ink from 0% to 10%, and at least one of DOP and ATBC from 1.0% to 5%. The composition is mixed and tailored to various designs for different exercise equipment, different parts and different portion of the exercise equipment. The internal body in the weight trainer, due to being mixed with the solid powder, has an extremely high density ranging from 0.5 g/cm.sup.3 to 6 g/cm.sup.3, preferably ranging from 4 g/cm.sup.3 to 6 g/cm.sup.3, so the weight trainer can have a high weight, even if fitted into the internal body with small volume.
    • 卫生练习设备包括具有竹炭粉,PVC,ZN-CA稳定剂,倾点降低剂,油墨和DOP和ATBC中的至少一种的组合物的热塑性弹性体。 优选竹炭为0.1%〜5%,PVC为35%〜56%,ZN-CA稳定剂为0.4%〜1.5%,倾点为0.5%〜1.5%,油墨为0%〜10% DOP和ATBC中的至少一个从1.0%到5%。 该组合物被混合并针对不同的运动设备,不同部位和不同部分的运动器材进行各种设计。 由于与固体粉末混合,重量训练机中的内部体积具有极高的密度,范围为0.5g / cm 3至6g / cm 3,优选为4g / cm 3。 在3至6g / cm 3之间,所以重量训练者可以具有很高的重量,即使体积小的内装物也装入内部身体。
