Abstract: PROBLEM TO BE SOLVED: To improve both electric conductivity and Seebeck coefficient, by arranging alloy whose Seebeck coefficient is relatively large, on the grain boundary of alloy whose electric conductivity is relatively large. SOLUTION: When a current is made to flow from the left direction to the right direction in an N-type thermoelectric element, the current flows selecting a part of higher electric conductivity. That is, the current flows selectively in grains of n-Bi2 Te3 alloy particles 2 which are comparatively large alloy particles, so that the electric conductivity of the N-type thermoelectric element becomes nearly equal to that of the n-Bi2 Te3 alloy and larger than that of the conventional Bi-Te-Se based alloy. Since the surfaces of the n-Bi2 Te3 alloy particles 2 are covered with Bi2 Se3 alloy particles 3, the part coming into contact with an electrode is Bi2 Se3 alloy particles 3.  The Seebeck coefficient determined by the material quality of the contact surface with t he electrode becomes nearly equal to the value of Bi2 Se3 , and is larger than the Seebeck coefficient of the conventional Bi-Te-Se. Both the electric conductivity and the Seebeck efficiency are improved, and the quality index is remarkably improved.

SOLUTION: A vibration type compacting machine such as a vibrating roller travels by rotating a rolling wheel 1 by a traveling driving hydraulic motor 24. When a shaking axis 10 is rotated by driving a shaking driving hydraulic motor so as to drive the vibrating roller, a moving eccentric weight 4 overcomes moment generated by pressurization of a pressing member 13 at a certain number of revolution and is rotated around an axis 3 to a maximum eccentricity position. In this state, the rotation of the shaking axis 10 is increased, and the vibrating roller is operated in a stationary rotation state.  On the other hand, when the rotation of the shaking axis 10 is decreased from the stationary rotation state, the moving eccentric weight 4 is rotated around the axis 3 in the direction that makes the eccentricity zero by the pressing member 13 at a certain number of revolution or less to return the moving eccentric weight 4 to a neutral position.
