To provide a configuration relating to storage of a computer, household electric appliances or furniture, and perishable products.

An experiment is performed by reversing a box without performing any change in various types of conventional software functions in a personal computer. Consequently, a hard disk, boards and connecting wires are inevitably put into a balanced state of receiving force resisting to attraction force from the ground surface and receiving aerodynamic lift from air. In this state, the personal computer is booted and a keyboard is operated to examine whether or not a CPU computing speed and other application software are improved. A functional improvement test is performed before and after the reversing, namely, conversion rates of the various types of applications are compared. As a result, an improvement in the speed is confirmed so as to confirm the significance of making the functional configuration suspended state.
