Title: Optical fiber type underwater sound detecting element
Inventor: TATSUMI TAMOTSU
IPC: G01H9/00
Filed: 1983-02-15
Abstract: PURPOSE:To obtain an optical fiber type underwater sound detecting element with which the influence of a water source can be separated by juxtaposing a detector formed by winding an optical fiber on the wall surface of a sheet metal case and adhering the fiber and the optical fiber of a hollow core solenoid having roughly the same winding length as that of said detector and operating differentially both. CONSTITUTION:An optical fiber 2 wound on the inside surface of a sheet metal case 1 formed of nickel is adhered, and an optical fiber 3 having roughly the same winding length as that of said fiber is wound on the outside of the case 1. The pulse light from light sources 11, 11' driven by a pulse generator 16 are made incident through semitransparent films 12, 12' to optical fibers 13, 13'. The back scattered light are reflected by the mirrors 12, 12' and are made incident to photodetectors 15, 15'. The outputs thereof are differentially added and are converted to the signal proportional to a sound pressure by a signal processing circuit 19. Said signal is displayed on a display 20 via a timing generator 17 and a masking circuit 18. Even if the depth increases, the back scattering intensity is differentially added and therefore the light except from the detector C, D parts is cancelled and the influence of the water depth is eliminated.

Title: Periodic pulse generating circuit
Inventor: FUKAWA KAZUHIKO
IPC: H03K3/78
Filed: 1988-02-05
Abstract: PURPOSE:To arbitrarily and correctly set the mean period of an output pulse without increasing the frequency of a reference oscillator by adjusting a timing through the use of a timing control part. CONSTITUTION:When a driving pulse is impressed to an input terminal C, a timing generating circuit 6 outputs a timing control value tk=kT/tau. The control value tk and a time (n) are compared by a comparing circuit 7. When both values coincide in a fixed error range, a timing pulse is outputted from the comparing circuit 7 and inputted to an output terminal 8 and the terminal C of the circuit 6. As the error range, + or -0.5 is used, the circuit 7 rounds off the control value tk, an integer value (v) is extracted, it is compared with the time (n), and an expression I is obtained. In the expression, round (x) is a function to round off (x), and deltak is the decimal value of -0.5<deltak<=0.5. From the expression I, an output pulse mean period Ta of k-number of pulse is made into T+deltaktau/k, consequently, the period Ta coincides with a necessary period T at the time of k infinity , and the mean period of the output pulse can be set at the T.
