IPC: G01N29/04
Filed: 1988-02-15
Abstract: PURPOSE:To improve the operation efficiency by sending ultrasonic wave pulses at the same angle of incidence corresponding individually to the different internal diameters of two vibrators. CONSTITUTION:In the boiler tube 1 formed by connecting tubes which differ in internal diameter, a vibrator 2 which corresponds to the large internal diameter D and a vibrator 3 which corresponds to the small internal diameter D' are arranged successively at right angles to the tube axis, and the quantities e1 and e2 of eccentricity of the vibrators 2 and 3 are so determined that the ultrasonic wave pulses 4 and 5 that the vibrators 2 and 3 send individually are at the same angle (i) to the corresponding tube internal surfaces, thus constituting an insertion type two-vibrator probe 6. Then the probe 6 is scanned in the tube 1 while being rotated around the tube axis and oblique flaw detection is carried out for the weld zones 7 of plural fitted members to the overall length of the outer peripheral surface of the tube with pulses 4 of the vibrator 2 for the part of the large internal diameter D and pulses 5 of the vibrator 3 for the part of the small internal diameter D'. Thus, oblique flaw detection is performed in an excellent state for the defect 8 of the weld zones 7 of the members.

Title: Ssb reception circuit
Inventor: KIKUCHI YASUTAKA
IPC: H04B1/16
Filed: 1993-02-22
Abstract: PURPOSE:To suppress charge/discharge in the case of non-signal in SSB reception by executing forcible discharge only when a non-signal period of a charge/ discharge circuit is continued for a reference period or over. CONSTITUTION:A reception signal (a) is amplified by an amplifier 3 and rectified by a rectifier circuit 4 in to a signal (b). The signal (b) is fed to a charge / discharge circuit 6 via a diode 5 to charge a capacitor 14. On the other hand, the rectified output (b) is compared with a reference voltage V1 at a comparator 16 and in the case of the output b>V1, the comparator 16 outputs a '0' level and in the case of b<=V1, the comparator 16 outputs a '1' level. A counter 17 counts number of clock signals by the output '1' of the comparator 16 and when the count reaches a non-signal reference time, a carry output is generated and a switch 18 is closed. That is, when the switch 18 is opened, since no discharge path is in existence in the charge/discharge circuit 6, the circuit is a charging circuit for the capacitor 14 and when the switch 18 is closed, the circuit is a parallel connection circuit comprising the capacitor 14 and a resistor 19, and then the charge in the capacitor 14 is rapidly discharged.
