摘要： PURPOSE:To make flaw detection over the entire surface of a pipe easy, by connecting plural pieces of single pig bodies wherein electronic circuits, etc. having a detection function, a calculation function, a memory function, etc. are contained separately, freely flexibly to each other and constituting the same movably in the pipeline. CONSTITUTION:The 1st single pig body 2A is provided with a sliding ring 8 of a small sliding resistance around the same so as to be moved together with the fluid in a pipeline 1 and contains therein a motor 9 for rotating the other single pig bodies 2B-2D and a battery 10. The 2nd body 2B is provided with an ultrasonic probe 12 on the side surface and has an electronic circuit 13 for detection internally. The 3rd body 2C is provided internally with an electronic circuit 15 for calculation. Further, the 4th body 2D is provided with a sensor 17 for position detection at the rear end and has an electronic circuit 18 for memory internally. These bodies 2A-2D are connected flexibly and are moved by the fluid flowing in the pipeline 1, whereby the entire surface of the pipe is scanned and is detected of any flaw.

摘要： PURPOSE:To improve a responding property and a damping characteristic, by detecting a load variation and executing the feedback. CONSTITUTION:This servomechanism has such a circuit configuration as adds signals obtained by multiplying an input (z) to a servomotor, a load (m) and a variation of the load m' by K1(t, e), K2(t, e) and K3(t, e), to the input (z) respectively. Also, each gain K1(te), K2(te) and K3(te) given by Ki(te)=Ki+Bi o e.zdt+Ci(ez) is changed so that a difference (e) between a standard model give by y'm=kmz and an output y' of the servomotor is reduced to zero. That is to say, when an adjusting parameter is varied in accordance with the ''integration + proportion'' adaptive rule, this servomechanism operates stably, following the standard model.
摘要翻译：目的：通过检测负载变化和执行反馈来提高响应特性和阻尼特性。构成：该伺服机构具有通过将输入（z）与伺服电动机，负载（m）和负载m'的变化乘以K1（t，e），K2（t，e））和K3（t，e）分别输入到输入（z）。此外，由Ki（te）= Ki + Bi ot e.zdt + Ci（ez）给出的每个增益K1（te），K2（te）和K3（te）被改变，使得由y'm = kmz给出的标准模型和伺服电机的输出y'减小到零。也就是说，当调整参数根据“积分+比例”自适应规则变化时，该伺服机构按照标准模型运行稳定。

摘要： PURPOSE:To enable the detection of the smallest leakage on line by rendering a white noise an output of a sound sensor attached to a pipeline to detect leakage position. CONSTITUTION:Outputs of sound sensors 11 and 12 attached to a pipeline at a proper space is amplified with an amplifier connected thereto and then, passed through a white color filter to render a white noise an output of sound sensors at the normal time without leakage. Then, an output of the white color filter is squared with a multiplication circuit and the squares Z1n and Z2n of the output of the white color filter at the normal time as preset are subtracted from the outputs Z1 and Z2 thereof to extract leakage sound components DELTAZ1 and DELTAZ2. When the leakage sound components thus obtained are sent to an averaging circuit respectively to determine the mean thereof and the ratio (r) of both is obtained with a devision circuit, the distance (x) to the leakage point B from the mounting position 1 of the sound sensor 11 can be found by the equation DELTA. Thus, the smallest leakage can be detected on line.
