摘要： PROBLEM TO BE SOLVED: To avoid errors during depth measurement even when a buried metallic tube or the like includes curve parts and branch parts to provide it with congestion and even when a commercial current, a signal current, or the like is passed through the buried metallic tube. SOLUTION: The probe method for a buried linear metallic object allows an AC current to pass through the buried linear metallic object 1, detects a change in a magnetic field generated thereby by a probe coil 2, and probes the buried position and depth of the buried metallic linear object. At least two burying-depth measurement methods are adopted and on the basis of measurement results by the methods, a depth measurement value is corrected. By discretely detecting depth measurement signals, removing a plurality of detected values close to a maximum value and a plurality of detected values close to a minimum value in a predetermined time, averaging and performing operations on remaining detected values, a depth measurement value in the time is obtained.

摘要： PROBLEM TO BE SOLVED: To radiate an electromagnetic wave into soil with good transmittance by composing a substrate by a dielectric where a relative dielectric constant is increased from the inside toward the outside in the thickness direction of a drill head. SOLUTION: An inclined surface 10 at a tip part 9 of a drill head 5 is formed by a substrate 15 consisting of a flat dielectric. In the tip part 9, the substrate 15 is provided. More specifically, a transmission antenna 16a and a reception antenna 16b are provided while facing the inclined surface 10. The antennas 16a and 16b are connected to an electric circuit 17 in the drill head 5.

摘要： PROBLEM TO BE SOLVED: To detect a tube joint, provided in a hidden place of soil or the like, with high accuracy by connecting tube joint detecting impedance elements to both end parts of a heating wire in an electricfusion-welded tube joint provided with the heating wire inside or on the inner surface of a tube joint body made of thermoplastic synthetic resin. SOLUTION: When an oscillation start command signal is supplied to an oscillating circuit 28 from a control circuit 38 through a line 39, the oscillating circuit 28 generates burst wave, so that electromagnetic field energy from a transmitting coil 27 is supplied to a tube joint device 20 and also supplied to a receiving coil 35. Receive waveform can therefore be obtained from the output of the receiving coil 35. When the excitation driving of the transmitting coil 27 is suspended, the electromagnetic field energy decreases with the lapse of time, and at this time, output obtained from the receiving coil 35 also decreases. A plurality of peak-to-peak value are therefore obtained by a level detecting means 37, and a place where this peak-to-peak value becomes the maximum is detected as the buried place of the tube joint device.

摘要： PROBLEM TO BE SOLVED: To improve detection sensitivity by suppressing signals reflected from the surface of ground and further enlarging the amplitude of signals reflected on underground embedded pipes by suitably selecting the length of a guide terminal part at a 1st section on a substrate. SOLUTION: 1st sections 55 and 56 on the upper surface of substrate 52 of antenna 51 for underground probing are extended on both sides of 1st direction along the substrate 52 with respect to a power feeding point 53. One 1st section 55 is composed of a main section 57 formed on the substrate 52 and a rising section 58 to rise while being inclined so as to get closer from a terminal part 159 near that power feeding point 53 to the power feeding point 53 and similarly, the other 1st section 56 is also composed of a main section 59 formed on the substrate 52 and a rising section 60 to rise while being inclined so as to get closer from a terminal part 61 near that power feeding point 53 to the power feeding point 53. A length L1 between free terminal parts 64 and 65 of main sections 57 and 59 at the 1st sections 55 and 56 along a 1st direction 157 is selected from 550mm to 620mm and when that length gets out of this range, the amplitude of signals reflected from the underground embedded pipes is lowered.

摘要： PURPOSE: To correct the characteristics of an antenna to prevent the deterioration of resolution and to suppress the change of an investigating video by deciding the coefficient of a filter based on the signal received by a reference antenna provided in addition to the antenna to be used. CONSTITUTION: First, changeover switches 20, 21 are connected to the sides of reference antennas 12a, 12b, and a changeover switch 22 is connected to the side of a received reference waveform memory 15. A testpiece 23 is inserted, a base band pulse is transmitted from a transmitter 10, received by a receiver 13, and the waveform is stored in the memory 15. Then, the switches 20, 21 are switched, and the received waveforms via comparison antennas 11a, 11b are stored in a received comparison waveform memory 14. Thus, the memory 14 stores the waveform Fm, and the memory 15 stores the waveform Fo. A comparison calculator 16 compares the waveform Fm with the waveform Fo to obtain filter coefficient data. The coefficient is set in a reverse filter 18 to correct the received waveform Fm, and video data is output.

摘要： PURPOSE:To precisely detect the position of the joint of a buried pipe from above the ground. CONSTITUTION:As a buried object detecting device 1 is moved on the ground surface 3 above a buried pipe 2, electric waves are sequentially emitted from the buried object detecting device 1 toward underground 4. The waves reflected from underground 4 are received by the buried object detecting device 1 and the time from emission of the electric waves to arrival of the reflected waves is signal processed to display the reflected image of the buried pipe 2 on a screen. The position of the joint 2a of the buried pipe 2 is determined while a bulge in a straight line in the reflected image on the screen, which appears at the position of the joint 2a of the buried pipe 2 when the ground surface immediately above the buried pipe 2 is moved parallel to the axis of the buried pipe 2, and a distortion in an arc in the reflected image on the screen, which appears when the ground surface is moved to pass the position of emission of the electric waves on the ground corresponding to the position of the bulge and to pass the buried pipe 2 diagonally, are employed as criteria for identification.
