Filed: 1979-07-03
Abstract: PURPOSE: To increase the accuracy for the magnetism test, by providing the device which gives correction to the magnetic flux distribution and thus ensure a uniform magnetic flux distribution within the material to be tested.  
     CONSTITUTION: Coil 8 detects the magnetic flux density at the center of exciting coil 2; and coils 9a and 9b detect the magnetic flux density at the end part of coil 2. The difference is detected 12 between the phase of the induced voltage of coil 8 corresponding to the phase of the main magnetic flux and the phase of the induced voltage of coils 9a and 9b each corresponding to the phase of the corrected magnetic flux. Then the detection output is applied to phase control circuit 13 to carry out the phase control for the induced voltage of coil 8 the voltage level of which is controlled through magnetic flux control circuit 11, and then applied to correcting coil 14 after amplification 15. Accordingly, the phase difference is eliminated between the main and corrected magnetic flux to realize a uniform magnetic flux distiribution within material 5 to be tested. As a result, a high-accuracy magnetism test is possible for many types of material 5 by one unit of test coil 1.

Title: Pipe for renewing existing pipeline and technique for renewing and repairing existing pipeline
Inventor: YAGI SHUICHI
IPC: F16L1/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To secure the sufficient opening diameter of an inserted pipe for a long period in the case of performing renewal and repair of an existing pipeline by forming a new pipe capable of being integrated with the existing pipeline in the case of performing renewal of the existing pipeline by inserting a synthetic resin pipe into the existing pipeline and forming the new pipe in this pipeline. SOLUTION: A synthetic resin pipe inserted into an existing pipeline is made to a pipe 1 for renewal in which a pipe 10 made of nylon having high elasticity and high strength is used as base material and a hot-melt adhesive layer 20 is formed on the outer peripheral surface. Since the pipe 1 for renewal is strongly fixed on the inner surface of the existing pipeline by the hot-melt adhesive layer 20 formed on the outer peripheral surface of the pipe 10 made of nylon, such inconvenience is not caused that the inserted pipe 1 for renewal is deformed with the lapse of time and an opening is decreased. Further, since the pipe for renewal inserted into the existing pipeline is the pipe made of nylon having high elasticity and high strength, its wall thickness can be made extremely thin and the bore of the pipeline after renewal is sufficiently secured.

Title: Sensor for detecting material in liquid by acoustic wave
Inventor: MORIIZUMI TOYOE
IPC: H03H9/68
Filed: 1987-04-08
Abstract: PURPOSE:To improve the sensitivity of detecting the specific material in a liquid to be detected by providing paired electrodes for impressing an AC voltage and paired electrodes for generating an AC voltage onto the same surface of a substrate formed of a piezo-electric material which generates leak surface acoustic waves and the cut surface and providing a layer to adsorb the specific material between both. CONSTITUTION:The comb-shaped electrodes 111, 112 for input and the comb-shaped electrodes 121, 122 for output are provided on the same surface of the piezo-electric substrate 10 and a receptor 3 is provided between both the electrodes. An input signal generated by an oscillator 15 excites the leak surface acoustic waves on the substrate 10 by the electrodes 111, 112. The leak surface acoustic waves propagate in the substrate 10 and the receptor 3 and are converted to an electric signal by the electrodes 121, 122. The output signal thereof is compared with the input signal generated by the oscillator 15 in a phase comparator 16. The phase difference between the two signals is the propagation delay time of the leak surface acoustic waves between the electrodes 111, 112 and the electrodes 121, 122. The propagation speed of the leak surface acoustic waves changes when the specific material in the liquid 7 to be detected is adsorbed in the receptor 3. The change quantity of the phase is thus measured by the comparator 16, by which the detection of the specific material is permitted.
