    • A noiseless weight training machine is provided. The machine comprises a base frame mounted on a floor, a rectangular weight frame installed on the base frame, a pair of parallel guiding rods extending vertically from the base frame, a plurality of weight blocks for traveling up and down along the guide rods, a weight block connecting unit for connecting weight blocks of a number of interest to a user, a cable for suspending the weight block connecting unit through a sheave supported by the ceiling of the weight frame, and a shock damper placed beneath the weight blocks. The shock damper damps shock and vibrations generated by the impact of lifted weight blocks returning against the remainder thereof to reduce impact noise while exercising. The machine further includes elastic members disposed on stoppers mounted beneath the lowermost of the weight blocks so as to support them. The elastic members absorb minor shock occurring when the lifted weight blocks fall on the remainder thereof or when all of the weight blocks are lifted and fall on the stoppers.
    • 提供无噪音的重量训练机。 该机器包括安装在地板上的基座框架,安装在基架上的矩形重量框架,一对从基座竖直延伸的平行引导杆,沿导杆上下移动的多个重物块, 重量块连接单元,用于连接用户感兴趣的重量块,用于通过由重物框架的天花板支撑的滑轮悬挂重物块连接单元的电缆,以及放置在重锤块下方的减震器。 冲击阻尼器减轻由于提升的重量块与其余部分的冲击而产生的冲击和振动,以减少运动时的冲击噪声。 机器还包括设置在安装在最下面的重块之下的塞子上的弹性件,以便支承它们。 当提升的重量块落在其余部分上时或当所有重量块被提升并落在止动件上时,弹性构件吸收发生的轻微冲击。

    • Defects of infrared optical fibers during fabrication are inspected. The optical fiber runs from a fiber fabrication apparatus to a winding device. An integration sphere with a photodetector is placed at a point of the path of the running fiber. A light source shoots a light beam obliquely at the side surface of the running fiber or vertically at the beginning end of the fiber. Some portion of the light beam becomes propagating light. The defects of the fiber scatter the propagating light. The photodetector detects all the power of lights reflected within the diffuse reflective surface of the integration sphere. The output power of the photodetector is heightened to a higher level when a defect exists in the integration sphere, and the output power is lowered to a lower level when the defect exists between the outlet of the integration sphere and the light source. The position and extent of the defects are estimated by the change of the output power of the photodetector.
    • 检查制造过程中红外光纤的缺陷。 光纤从纤维制造装置运行到卷绕装置。 具有光电检测器的集成球放置在运行光纤的路径的一个点处。 光源在光纤的起始端以斜行的方式射出光束,或在垂直方向上射出光束。 光束的一部分变成传播光。 纤维的缺陷会散射传播光。 光电检测器检测在积分球的漫反射表面内反射的光的全部功率。 当积分球存在缺陷时,光电检测器的输出功率提高到更高的水平,并且当积分球的出口与光源之间存在缺陷时,输出功率降低到较低的水平。 通过光电检测器的输出功率的变化来估计缺陷的位置和程度。
