PRESSURE CONTAINER, AND BUOYANT BODY AND EXPLORING DEVICE WHICH ARE PROVIDED WITH THE SAME

摘要

The invention relates to a pressure container having improved improved reliability of pressure-resistant performance and sealing performance at a connecting portion between outer shells, and a buoyant body and an exploratory apparatus provided therewith. a pressure container includes a semispherical first outer shell (2) made of ceramics, a semispherical second outer shell (3) made of ceramics, a straight cylindrical third outer shell (4) made of ceramics, and annular first and second connecting bodies (5, 6) interposed between the first outer shell (2) and the third outer shell (4) and between the second outer shell (3) and the third outer shell (4), and made of materials at least one of which has an elastic modulus smaller than those of the first to the third outer shells (2 to 4).
