摘要： PROBLEM TO BE SOLVED: To diagnose and evaluate a waterproof capacity (deterioration degree) over a wide range in a non-destuctive manner directly, quantitatively, and inexpensively only by temporarily providing an electrode merely without applying a large-scaled device to the rooftop waterproof layer of an established or existing building. SOLUTION: A large number of electrodes are temporarily provided and arranged on the rooftop waterproof layer of the building through a conductor layer and used to calculate electric characteristics to evaluate the deterioration degree of the waterproof layer from the correlation with water permeability. Typically, an arbitrary one internal current electrode among a large number of electrodes is set to an internal current electrode and one separate electrode is set to a reference electrode and a plurality of electrodes on a measuring line containing the reference electrode are set as measuring electrodes. An external current electrode is installed on the main body of the building to feed a current across the current electrodes and the potential difference between the reference electrode and the measuring electrode is measured to calculate distance potential attenuation characteristics and the degree of the deterioration in the vicinity of a measuring region is evaluated from the correlation with water permeability.

摘要： PURPOSE:To orient the position of a laid cable without opening a trough cover. CONSTITUTION:An eddy current is generated in an aluminum cover 8 of a cable 7 laid in a trough 6 by a sensor part 1 and magnetism generated by this eddy current is detected by the sensor part 1. This detection signal is converted by a microcomputer 3 into a signal corresponding to a separation distance Y and then this separation distance Y is displayed on an LED array of an output part 5. Since a position of the laid cable 7 can be oriented without opening a cover of the trough 6, workability of cable inspection can be remarkably enhanced.

摘要： PURPOSE:To enable the sufficient suppression of coupled vibration of a pipeline and in its turn prevent the soundness of the pipeline from being impaired by constraining the external wall of the pipeline by a cylindrical vibration damping member, and forming the axial length of the cylindrical vibration damping member to be longer than the wavelength of the axial mode of the coupled vibration. CONSTITUTION:The coupled vibration of the vibration mode of a pipeline wall and higher-order acoustic mode of a fluid in a pipeline has circumferential, radial and axial modes. Out of these modes, the circumferential and radial modes are suppresed by constraining the external wall of the pipeline 3 by a cylindrical vibration damping member 10. On the other hand, the wavelength of the axial mode has a characteristic uniquely determined by the diameter and length of the pipeline 3 and the acoustic velocity of the fluid. The axial mode can be therefore suppressed sufficiently if the axial length of the cylindrical vibration damping member 10 is formed longer than the wavelength of the axial mode of the coupled vibration.
