    • A Sagnac interference type optical fiber vibration sensor includes two optical fiber loops arranged along a structure, and a vibration sensor main body which detects the vibration caused to the structure via the two optical fiber loops. A sensitivity of one of the two optical fiber loops for detecting a vibration decreases with a distance from one end to an other end, while a sensitivity of an other of the two optical fiber loops increases with a distance from the one end to the other end. The main body includes a portion for determining whether the vibration occurred to the structure based on a sum of outputs produced via the two optical fiber loops, and a portion for determining a position where the vibration occurred based on an output ratio which is a difference between the outputs produced which is divided by the sum of the outputs produced.
    • Sagnac干涉型光纤振动传感器包括沿着结构布置的两根光纤回路,以及一个通过两个光纤回路检测对该结构产生的振动的振动传感器主体。 用于检测振动的两个光纤环中的一个的灵敏度随着从一端到另一端的距离而减小,而两个光纤环中的另一个的灵敏度随着从一端到另一端的距离而增加 。 主体包括用于基于通过两个光纤回路产生的输出的总和来确定结构是否发生的部分,以及用于基于作为第二光纤回路之间的差的输出比来确定发生振动的位置的部分 所产生的产出除以产出的总和。

    • A synchronizing device and a synchronizing method whose constitution is simple and whose operation is easy to be stabilized are provided. A subtracter subtracts a value of a read pointer which calculates number of data read-out from a memory device from a value of a write pointer which calculates number of data written in the memory device to obtain subtraction value, thus causing the subtraction value to be given to a judging unit as detection data remaining quantity. The judging unit outputs comparison result signal while comparing detection data remaining quantity with reference value. A number of data increasing/decreasing unit receives data from a decoder for decoding data of the memory device. The number of data increasing/decreasing unit causes remaining quantity of data of the memory device to be prescribed value with data reading-out speed of the memory device controlled in such a way that it controls quantity of data outputted, while replying to comparison result signal from the judging unit.
    • 提供了一种构造简单并且操作容易稳定的同步装置和同步方法。 减法器从计算写入存储器件中的数据的写指针的值计算从存储器件读出的数据数的读指针的值,以获得减法值,从而使减法值为 给予判断单位作为检测数据剩余量。 判断单元输出比较结果信号,同时将检测数据剩余量与参考值进行比较。 多个数据增加/减少单元从解码器接收数据以对存储器件的数据进行解码。 数据增加/减少单元的数量使得存储器件的数据的剩余量成为规定值,其中存储器件的数据读出速度被控制,使得它控制输出的数据量,同时响应比较结果信号 来自判断单位。
