摘要： PURPOSE:To make mechanism efficiency ever so better, by supporting a friction ball rolling element with a rolling friction mechanism, while pressing the friction rolling element to a friction surface being locked to both input and output shafts under pressure. CONSTITUTION:Each of friction ball rolling elements 8a and 8b is supported by a thrust bearing 5 and a bearing 10 in combination, while these rolling elements 8a and 8b are pressed against each of friction surfaces 16 and 14 being locked to both input and output shafts 1 and 17 by means of a pressure spring 30 and a plate spring 6 under pressure. With this constitution, since these friction ball rolling elements 8a and 8b are eventually pressed coherent to these friction surfaces 14 and 16 through a technique of rolling friction by the bearing 10 and the thrust bearing 5, any loss due to friction is as little as negligible and, what is more, there is no loss by force, thus mechanical efficiency comes yet better as a whole.
摘要翻译：目的：为了使机构效率更好，通过用滚动摩擦机构支撑摩擦球滚动元件，同时将摩擦滚动元件按压到在压力下被锁定到输入和输出轴的摩擦表面。构成：摩擦球滚动元件8a和8b中的每一个由推力轴承5和轴承10组合支撑，同时这些滚动元件8a和8b被压靠在锁定到输入和输出轴的每个摩擦表面16和14上 1和17通过压力弹簧30和板簧6在压力下。利用这种构造，由于这些摩擦球滚动元件8a和8b通过轴承10和推力轴承5的滚动摩擦技术最终被压实到这些摩擦表面14和16上，所以由于摩擦而引起的任何损失都可以忽略不计更重要的是，没有任何的武力损失，机械效率总体来看还是比较好的。

摘要： PURPOSE:To obtain a focus detector capable of measuring so long as a prescribed lightness is available, by judging fucusing in accordance with the sum of output change amts. of photodetectors depending upon forward and backward movement of an objective lens. CONSTITUTION:An image is focused on a diffracting element or an optical element with an objective lens, this image is focused on many photodetectors elements 1a-8a with a focusing lens, and outputs V1-V8 are taken out through electrode plates 1b-8b. The front focus and the rear focus are judged in accordance with the positive or negative sum DELTAVt of output change DELTAV1-DELTAV8 of each element 1a-8a due to the forward and backward movements of the objective lens, and focusing can be detected from the time of DELTAVt=0. Since detection of contrast or phase difference or the like is dispensable, the measurement is made possible so long as a prescribed lightness is available.
摘要翻译：目的：通过根据输出变化量的总和判断融合，获得能够测量的焦点检测器，只要指定的亮度可用。取决于物镜的向前和向后运动的光电检测器。构成：图像聚焦在具有物镜的衍射元件或光学元件上，该图像聚焦在具有聚焦透镜的许多光电检测器元件1a-8a上，并且通过电极板1b-8b将输出V1-V8取出。根据物镜的向前和向后移动，根据每个元件1a-8a的输出变化DELTAV1-DELTAV8的正或负和DELTAVt来判断前焦点和后焦点，并且可以从时间检测聚焦的DELTAVt = 0。由于对比度或相位差等的检测是不必要的，只要规定的亮度可用，就可以进行测量。
