TEMPERATURE DIFFERENCE DRIVE DEVICE AND ELECTRONIC APPARATUS PROVIDED WITH IT

Title:

TEMPERATURE DIFFERENCE DRIVE DEVICE AND ELECTRONIC APPARATUS PROVIDED WITH IT

Document Type and Number:

Japanese Patent JP2001329945

Kind Code:

A

Abstract:

To provide a temperature difference drive device capable of efficiently utilizing thermal energy due to temperature variation and to provide an electronic apparatus provided with it.

When a rotor 11 of a generator 10 is rotatively driven by increasing the mechanical energy of a thermo-element 20 for generating the mechanical energy by the variation of ambient temperature with a gear train 40, the number of rotations of the rotor 11 is controlled at a predetermined one by a control part 50. By setting the number of rotations to the best generation efficiency in setting the number of rotations of the rotor 11 of the generator 10 for the control part 50, the generator 10 always exerts the highest generation efficiency, so that the thermal energy can be used with excellent energy use efficiency.
