Title:
TANK
Document Type and Number:
WIPO Patent Application WO/2008/146765
Kind Code:
A1
Abstract:
A tank (300) for storing gas is provided with a dye capsule layer (16) including
capsules containing dye or with a shock recording layer formed on the outer surface
of the tank body (10). The shock recording layer has, for example, a heat-insulating
material layer (14) formed on the outer surface of the tank body (10), having a
heat-insulating function, and capable of holding deformation, a dye capsule
layer (16) formed on the outer surface of the heat-insulating layer and including
capsules containing dye, and a dye absorbing layer (18) formed on the outer surface
of the dye capsule layer (16) and capable of absorbing dye. By a shock, the dye
released from the dye capsule layer (16) is absorbed into a dye absorbing layer
(18) of the tank. The dye exudes on the surface of the dye absorbing layer (18)
and spreads. The degree of shock given to the tank (300) is estimated from the
degree of spread of the dye or the degree of density of the dye.
