摘要： A reflectomerry method and device are disclosed for measuring the loss distribution of an optical waveguide on the basis of Rayleigh back-scattered signals from an optical waveguide under test. Light output from a tunable low-coherent. light source, in which laser oscillation is suppressed, is divided into first and second lights. Local oscillator light is generated by propagating the first light over a variable optical path length determined by a movable mirror. The second light is used as a probe light which is launched into the optical waveguide under test. The local oscillator light is combined with light reflected from the waveguide under test. An average value of the Rayleigh back-scattered signals from the waveguide under test is obtained at respective center wavelengths of the light source by measuring the intensity of the combined light while maintaining the variable optical path length constant and varying the center wavelength of the light source. The average value of the Rayleigh back-scattered signals is thus obtained at a point of the waveguide under test. After changing the variable optical path length by incrementally shifting the movable mirror, the above procedure is repeated to obtain an average value of the Rayleigh back-scattered signals at successive points of the waveguide under test. By thus reducing the number of times the mirror needs to be shifted, the time required for measuring the entire waveguide is reduced.

摘要翻译： 公开了一种基于来自被测光波导的瑞利反向散射信号测量光波导的损耗分布的反射体法和装置。 光输出从可调低相干。 激光振荡被抑制的光源被分成第一和第二光。 通过在由可移动镜确定的可变光程长度上传播第一光而产生本地振荡器光。 第二个光用作探测光，其被发射到被测光波导中。 本地振荡器光与被测波导反射的光结合。 通过在保持可变光路长度恒定并改变光源的中心波长的同时测量组合光的强度，在光源的各个中心波长处获得来自被测波导的瑞利反向散射信号的平均值 。 因此，在被测波导管的点处获得瑞利反向散射信号的平均值。 通过递增地移动可移动反射镜来改变可变光程长度后，重复上述步骤以获得被测波导的连续点处的瑞利反向散射信号的平均值。 通过减少反射镜需要移动的次数，减少了测量整个波导所需的时间。

摘要： The specification discloses a piezoelectric motor which comprises an actuator and a rotor. The actuator includes a frame which has at least three arms extending from the center of the frame in a radial direction so that tip portions of the arms are situated on the same circumference. The actuator further includes multilayer piezoelectric elements formed by stacking a plurality of piezoelectric sections along a stack axis. The elements are placed respectively between adjacent arms in the frame so as to make the adjacent arms symmetrical to each other in regard to a line passing through the center and perpendicular to the stack axis. The rotor is supported in a freely rotatable manner around an axis passing through the center of the frame. The rotor has an inner wall inscribed with the tip portions of the arms and is rotated with a driving force generated on the tip portions when driving voltages having a predetermined phase difference from each other are applied to the multilayer piezoelectric elements.

摘要： The present invention provides a waterproof box which can improve water performance and work efficiency, and can reduce space. When washing water hits in the lower surface (33h) of first waterproof portion (33) of an upper cover (15), spay is generated. At this time, an outer surface (30b), which is formed in a tapered shape, of first waterproof portion (30) abuts on an inner surface (33g), which is formed in a tapered shape, of the first waterproof portion (33). Further, the outer surface (30b) engages with the inner surface (33g). As a result, the inlet of a minute path (27) is closed. Even if water leaks, force of the water is reduced because the water enters in a groove (33b or 35a). The water in which force of the water is reduced falls down.
