Title: Working face forward survey system, method thereof, and tunnel excavating method
Inventor: HIRANO SUSUMU
IPC: G01V1/06
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To eliminate the interruption of a tunnel excavating work for a working face forward survey by measuring and recording the seismic wave having a blasting in the tunnel excavation as a focus by a seismograph. SOLUTION: A seismograph 1 for sensing an initial motion by a focus and a waveform recording seismograph 2 for measuring the seismic wave are set within a tunnel T. A recording device 3 reads and records the measured signal of seismic wave of the seismograph 2. Thus, the seismic wave having the blasting of a certain working face on an excavating surface as the focus can be recorded. The recorded seismic record is transmitted to an analyzing device 4 through a communication line by use of a data transfer program within a controller 3b. The analyzing device 4 corrects the amplitude of the seismic record by use of the seismic record to determine the reflection coefficient sequence of reflected wave by a geological change in the front of the working face, and determines the stratum cross section from the reflection coefficient sequence.  The seismic wave can be recorded for survey without interrupting the tunnel excavating work, and since the blasting is performed several, times in a day, a plurality of seismic records can be provided within a short period to enhance the precision of the survey.

Abstract: PROBLEM TO BE SOLVED: To provide a polyimide powder by bringing a polyimide solution comprising a polyimide having structural units represented by a specific formula and a phenolic solvent into contact with a poor solvent for the polyimide and separating the crystals thus deposited. SOLUTION: A diamine, such as 4,4'-bis(3-aminophenoxy)biphenyl, and a tetracarboxylic acid anhydride, such as pyromellitic acid dianhydride and biphenyltetracarboxylic acid dianhydride, are added to a phenolic solvent, such as m-cresol, and the mixture is heated under stirring for a predetemined time. After completion of the reaction, the reaction solution is maintained at a temperature above approximately 50 deg.C and below the boiling point of a poor solvent, such as toluene, and the poor solvent is added thereto dropwise in an amount of not less than about 10 times that of the polymer powder and at a rate of addition of not more than 6 times the theoretical yield of the polymer powder per hour.  The thus-deposited crystalline powder of a polyimide having structural units of formula I (wherein X is formula II; R1 to R3 are each H, a lower alkyl, phenyl, biphenyl, etc.; Y is formula III) is separated by filtration under pressure and dried in an atmosphere of nitrogen to obtain a polyimide powder.

Filed: 1987-05-19
Abstract: PURPOSE:To keep the continuity of a reproducing image and a reproducing sound by producing a pseudo-tracking signal in place of a tracking signal if such a tracking signal among plural tracking signals is unable to be read out. CONSTITUTION:A difference between the tracking signals fP1 and fP2 is detected by a comparator circuit 11, and if this difference is large, either of these tracking signals is judged as not to be read out, and then a changeover signal is outputted from the comparator circuit 11 to a 2nd switch circuit 10, so that the 2nd switch circuit 10 is controlled to be changed over, so as to impress only a larger detection output out of detection circuits 4 and 5 to two terminals of a differential amplifier 6 respectively. By this method, the output from the differential amplifier 6 becomes '0', and hence a reproducing needle continues to trace an information bit train which has been traced, so that the continuity of the reproducing image and the reproducing sound can be kept accordingly.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To reduce a problem of the pressure equalization of the free surface of ink in an acoustic ink printer using a constant flow rate ink feed system. SOLUTION: An acoustic ink printing head 10 includes a channel 26 having an ink inlet 18 and an ink outlet 20. A plurality of acoustic lenses are arranged adjacent to the channel 26 and the focusing to the free surface of ink is performed so that the focal distance of at least one of the acoustic lenses 28 is different from that of the other one of them. When the printing head is planned so that pressure lowers continuously along the route between the inlet and the outlet, the focal distance of the acoustic lenses is reduced between the inlet and the outlet and the stepwise reduction of the surface level of ink is compensated.  Since each of the acoustic lenses is adjusted so as to have a focal distance ensuring the focusing predetermined acoustic frequency on the surface level of the ink flowing on each of the lenses, the non-uniformity of the size and speed of a droplet and distance characteristics is reduced.
