摘要： PROBLEM TO BE SOLVED: To disclose an accelerometer for measuring acceleration and a manufacturing method of accelerometers. SOLUTION: In one embodiment, the accelerometer is provided with a frame, a mass movably suspended from the frame, a fixing element having a circular surface and immovable with respect to the frame, a movable element having a circular surface and movable with the frame, and a detection coil of an optical waveguide wound on the circular surfaces for detecting the movement of mass, corresponding to the acceleration on the basis of detection results of changes in the length of the detection coil by an interferometer. The accelerometer manufacturing method includes both a step of suspending the mass in the frame and a step for winding the optical waveguide on the circular surfaces. The sensitivity of the accelerometers and their low manufacturing cost enable them to be used for incorporating into ocean bottom cables for earthquake monitoring and prediction. The accelerometers can be used as inline accelerometers or crossline accelerometers. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：公开一种用于测量加速度的加速度计和加速度计的制造方法。解决方案：在一个实施例中，加速度计设置有框架，从框架可移动地悬挂的块体，具有圆形表面并且相对于框架不可移动的固定元件，具有圆形表面并可与框架，以及根据由干涉仪的检测线圈的长度变化的检测结果对应于加速度的卷绕在圆形表面上的光波导的检测线圈。加速度计制造方法包括将质量块悬挂在框架中的步骤和将光波导卷绕在圆形表面上的步骤。加速度传感器的灵敏度和低制造成本使得它们可以用于结合到海底电缆中进行地震监测和预测。加速度计可用作直列加速度计或交叉加速度计。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method and a system for executing treatment of cable terminals and integration of sensors in a sensor station, in an ocean-bottom seismometer (OBS) cable array. SOLUTION: The sensor station includes a housing for various sensor constituent elements. The sensor station can house surplus-length parts of any one data transmission member which does not have to be divided in the sensor station, and one or more divided data transmission members can be connected to the sensor constituent elements. The sensor station controls any one of the strength element of the cable array. COPYRIGHT: (C)2006,JPO&NCIPI
