Title: Underwater acoustic signal detector
Inventor: KANEKO ISAO
IPC: G01S3/803
Filed: 1989-03-28
Abstract: PURPOSE:To achieve a higher accuracy of recognition of a sound emitting source by determining a correlation among a simulation spike signal of a spike signal expected to be generated from a sound emitting source and a spike signal of the sound emitting source received. CONSTITUTION:A representative pattern of a spike-oriented simulation signal expected to be generated from a sound emitting source is stored previously into a simulation section 11 based on acoustic material as a result of a past analysis and imparted a spectral change corresponding to a kinematic state or the like of the sound emitting source trapped to be supplied to a correlation section 12 as simulation signal by an external command. So, the correlation section 12 repeats a correlation 17 between a received signal obtained from a synthesization of the spike signal of the sound emitting source and an underwater noise to be outputted to a display section 13 each time. Here, according to a gram display of a correlation output, a maximum correlation output is generated at a position of a correlation delay time as indicated by P and at another correlation delay time having no correlating property and points in irregular forms being dispersed at random. Thus, a plurality of spike signals from the sound emitting source are all utilized as one signal thereby achieving a higher accuracy of recognition of existence thereof.

Title: Magnetostriction transducer
Inventor: GOTOU NORIO
IPC: H01L41/12
Filed: 1979-06-25
Abstract: PURPOSE:To reduce the cost while attaining miniaturization by exciting a single elastic wave in lateral wave mode, by arranging both conductor paths so that when electric currents are flowed through two conductor paths of a thin magnetostrictive plate in the same direction, the distribution of magnetic fields out of phase with each other will be obtained. CONSTITUTION:When an electric current is flowed from A1 of conductor path 12, a circular magnetic field is provided to alternate conductor paths 12 and 13. Since a bias magnetic field is applied in direcion +x, (x)-directional magnetostrictive values of parts A1-A6 and A1'-A6' of conductor paths 12 and 13 to position (x) change out of phase between surface side (a) and reverse side (b). As a result, exciting an elastic wave in longitudinal wave mode generated due to volume elasticity is sufficiently suppressed in magnetrostrictive plate 11 and only an elastic wave in lateral wave mode generated due to shift elasticity is excited. Therefore, device dimensions are reduced to about half as compared with a transducer that uses elastic waves in longitudinal wave mode, so that miniaturization can be attained.
