摘要： PROBLEM TO BE SOLVED: To simply and accurately perform inclination compensation without being affected by human factors. SOLUTION: This inclination compensator 1 is used for compensating an inclination of a vibration detector 2. The vibration detector 2 comprises a permanent magnet 22 and a coil 23. The permanent magnet 22 is fixed in a case body 21 while the coil 23 is attached to a pendulum 25. The vibration detector 2 causes a vibration of the pendulum 25 to generate a voltage across the coil 23 corresponding to the size of the vibration for vibration detection. This inclination compensator 1 is equipped with a drive means 11 for changing the inclination angle of the case body 21 to the horizontal, a resonance circuit part 13 comprising an amplifier 131 for amplifying a voltage generated in the coil 23 for feeding back the amplified voltage to an input of the amplifier 131, a determination means 14 for determining whether or not the voltage value of the voltage amplified by the circuit part 13 exceeds a prescribed value, and a drive control means 12 for stopping the drive of the drive means 11 when it is determined by the determination means 14 that the voltage value exceeds the prescribed value.

摘要： PROBLEM TO BE SOLVED: To provide an earthquake observation method capable of surely discriminating noise vibration in the vibration observed with a seismometer. SOLUTION: The vibration observed with a seismometer is disintegrated into intensity level for the frequency components of which specific frequency of vibration is supposed to be a frequency in a range of 15 to 25Hz, for example 20Hz. The vibration level of the frequency component is set to be a20dB, the noise level of the vibration is set to be an dB and the vibration level at the vibration frequency fp Hz giving the peak of the vibration is set to be ap dB, and then the hollowing equation is established, r20=(a20-an)/(ap-an)×100. In the case r20(%) exceeds a specified value, for example 60(%), it is judged a noise, and that vibration is eliminated.

摘要： PROBLEM TO BE SOLVED: To detect the elliptic wave of the seismic wave and easily and accurately separate the main wave by determining the signal wave deformation of the seismic wave measured along orthogonal axes, and discriminating the amplitude on the basis of the amplitude ratio. SOLUTION: The acoustic or seismic wave reflected by an underground fault structure is received by one or multiple receivers R at least in two orthogonal directions. A processor 1 A/D-converters 2 this reception signal. A calculating element 3 calculates the change of the azimuth of the plane including the axis of the pickup in the vertical direction and the change of the azimuth of the plane including the axis of the pickup of the horizontal direction to the reference plane in the vertical direction including the position of the focus and the positions of the receives R. A filter processor 4 discriminates the amplitude of each signal wave deformation by the set reference based on the amplitude ratio of the signal generated from each signal wave deformation and erases the elliptic wave. The main wave of the seismic wave can be easily and accurately separated and detected.

摘要： PURPOSE: To prevent the erroneous judgment of earthquake and interruption of gas supply based on the erroneous judgment. CONSTITUTION: When disturbance occurs, a disturbance signal removing means 12 removes ON/OFF signals having a natural oscillation frequency caused by the disturbance from the ON/OFF signals of a seismoscope 8. Then an inferring means 13 infers whether or not the disturbance is caused by an earthquake. Or, the means 12 removes initial ON/OFF signals having a disturbed oscillatory waveform from the ON/OFF signals of the seismoscope 8 and the means 13 infers whether or not the disturbance is caused by an earthquake.

摘要： PURPOSE: To judge whether earthquake data frame discrepancy is within an allowance range or not by selecting the width of an image as symmetry axis, dividing data around the symmetry axis, making the first and second data sets and comparing the data sets with a preset collating reference. CONSTITUTION: The results of earthquake testing groups are stored in an outside memory 210, prepared and modified to predict the image of earthquake data with specific symmetry around the axis. After they are modified, a device 200 is activated to read one frame of the earthquake data from a device 210 into an inside memory 220. An axis detector 240 accesses to the earthquake data and selects the axis as a symmetry axis. The maximum strength position is judged by a peak detecting technique. The earthquake data frame is sent to an edge detector 250 and a data point showing discontinuity in the data is identified, stored in an edge list and sent to a dividing means 260. The second edge list and the first edge list are collated by a collating device 160.

摘要： PURPOSE: To provide an accurate cross sectional distribution for a porosity, a coefficient of water permeability or the like even in noisy environment by using an oscillation source for pseudo random code vibration energy and propagating the vibration energy from the oscillation source to a receiver directly via a tomography across survey holes. CONSTITUTION: A pseudo noise source (PRBS oscillation source) to generate regular waves of pseudo random binary sequence(PRBS) is used as an oscillation source 10, and a hydrophone is used as a receiver 12. In this case, a plastic casing of 5" diameter is formed at a survey pit 11, and the PRBS oscillator 10 is laid in the casing. Thereafter, the oscillator 10 is excited with a PRBS code generator 21 and a power amplifier 20. The vibration energy so generated is received with hydrophones 13 and 12 arranged in a survey hole 14 and on the ground. Then, the received signals are amplified at a step 23 and recorded at a step 22. Subsequently, the PRBS oscillator 10 is moved to positions 10' and 10", and a similar measurement process is repeated. As a result, many tomography images on a propagation route can be obtained. When noises are mixed, a correlation with the PRBS code is established to identify the noises.

摘要： PURPOSE: To obtain a seismoscope device which is improved in the ability of detecting the knocking sound produced by a living human being enclosed due to a disaster. CONSTITUTION: A twin T-tube filter 62 connected to the output of a seismoscope is composed of pluralities of mutually connected resistors 82, 84, and 86 for charging and capacitors 88, 90, and 92 and an output circuit generates the signal component generated by a survivor. To the charging current paths between the related resistors and capacitors, CMOS switches 94 for controlling the currents of the paths are connected. A band width control circuit 104 applies an adjustable feedback voltage across the output and input of the filter 62. A variable duty cycle generator 102 controls the tuning and center frequency of the filter 62 by controlling the duty cycle of the switch 94. The generator 102 has an oscillator and the output of the generator 102 having a relatively high frequency is supplied to a comparator together with a floating variable reference voltage.
