Abstract

A storage apparatus including one or plural storage devices installed in a housing, a bag that is internally charged with a fluid and caused to contact the storage device, and an internal pressure regulator that regulates the internal pressure of the bag.

First claim

What is claimed is:

1. A storage apparatus, comprising:
one or a plurality of storage devices installed in a housing;
a bag that is internally charged with a fluid and that contacts the one or a plurality of storage devices; and
an internal pressure regulator that regulates the internal pressure of the bag.

2. The storage apparatus of claim 1 , wherein the one or a plurality of storage devices include a planar surface, and the bag is disposed in contact with the planar surface.

3. The storage apparatus of claim 2 , including a plurality of the storage devices disposed such that the planar surfaces thereof oppose each other across a space, wherein the bag is disposed in the space and in contact with each of the opposing planar surfaces.

4. The storage apparatus of claim 1 , wherein the internal pressure regulator includes an open/close valve that changes a communication state between the interior and the exterior of the bag.

5. The storage apparatus of claim 1 , wherein the internal pressure regulator includes:
an inflow regulator that regulates inflow of the fluid to the bag interior; and
an outflow regulator that regulates outflow of the fluid from the bag interior.

6. The storage apparatus of claim 5 , further comprising a fluid circulation device that circulates the fluid between the interior and exterior of the bag.

7. The storage apparatus of claim 6 , further comprising a cooling device that cools the fluid flowing into the bag.

8. The storage apparatus of claim 5 , further comprising:
an acceleration sensor that detects acceleration of the storage device; and
a controller that controls the inflow regulator and the outflow regulator based on the acceleration detected by the acceleration sensor.

9. The storage apparatus of claim 1 , wherein the bag further comprises:
a liquid charged section charged with a liquid; and
a gas charged section disposed inside the liquid charged section and charged with a gas.

10. The storage apparatus of claim 9 , wherein the internal pressure regulator regulates the internal pressure of the gas of the gas charged section.

11. A storage apparatus manufacturing method, comprising:
installing one or a plurality of storage devices, and a bag that contacts the one or a plurality of storage devices, inside a housing; and
regulating the internal pressure of the bag by regulating an amount of fluid in the bag interior, and shifting a resonance frequency of the one or a plurality of storage devices in contact with the bag away from a frequency at which the performance of the one or a plurality of storage devices deteriorates.

12. A storage apparatus measurement method, comprising:
vibrating a storage device and measuring a specific frequency at which the performance of the storage device deteriorates; and
vibrating the storage device in an installed state in a housing and measuring the resonance frequency of the storage device; and
comparing the specific frequency to the resonance frequency.
