摘要
PROBLEM TO BE SOLVED: To provide a self-floating type submarine earthquake observing apparatus wherein the whole apparatus is light, resonance to earthquake motion in the horizontal direction is suppressed, the natural frequency of a built-in apparatus is increased, and resonant noise is made frequencies outside the observation frequency band, by using constitution equipped with vibration-proof material between the built-in apparatus and the wall surface of a pressure tight vessel. ;SOLUTION: Between the built-in apparatus 13 and the pressure tight vessel 15, the vibration-proof material 19 for suppressing resonance in the built-in apparatus which is generated by earthquake motion in the horizontal direction is installed to cover a part of the upper surface and the lower surface and the side surface of the built-in apparatus 13.;COPYRIGHT: (C)2001,JPO
