Title: Sonar device
Inventor: HANAMURA SHINICHI
IPC: G01S7/523
Filed: 1984-12-10
Abstract: PURPOSE:To make possible the execution of three-dimensional scanning in real time with high resolving power with extremely simple constitution by executing vertical plane scanning, supplying the output for each of vertical split beam to a horizontal phase matching part which scans while matching the phases over the horizontal plane of a hydrophone and executing the three-dimensional scanning of the wave receiving plane of the hydrophone. CONSTITUTION:The scrupulous horizontal phase matching 3 and the scanning thereof by the combination of Quadrature phase shifting and matching and the delayed phase matching by a charge transfer device CTD are realized in real time on the horizontal plane of the hydrophone array 1 in a sonar device of a serial phase shift beam former type utilizing CCD. The phase matching by only the sampling shift is realized by a split beam method in a vertical phase matching part 2 by making use of the characteristic that the phase matching process is extremely simple in the case of, for example, 90 deg. phase difference of the adjacent hydrophones on the vertical plane. The three- dimensional scanning of the high resolving power is thus made possible even under the operating conditions under which the pulse width is required to be made as short as possible and the length of the hydrophone array is required to be made as large as possible.

Title: Printed circuit board and its manufacture
Inventor: SOGO HIROSHI
IPC: H05K1/09
Filed: 1993-10-20
Abstract: PURPOSE:To prevent corrosion by connecting a conductive paste to circuit copper foils by way of a base metallic layer whose standard monopole potential is baser than the metal contained in the conductive paste. CONSTITUTION:A conductive paste made of metallic particles 4 and an epoxy resin 5 is charged into a through hole by means of a printing method using a detachable film 2 as a mask. After the detachable film 2 is peeled, electrolytic copper foils 6, on which a base metallic layer 7 whose standard monopole potential is baser than the metallic particles 4 contained in the conductive paste is formed on the surface, are overlaid on both sides and bonded by heating and pressing. Consequently, if a corrosive current flows through metals contained in the conductive paste due to moisture and impurities such as chlorine ions and corrosion starts because the conductive paste is in contact with the metal whose standard monopole potential is base, a sacrificial anode dissolution current equivalent to anticorrosive current flows to keep the potential at a cathode anticorrosive potential, thus stopping the corrosion.
