The present invention is to provide a laminate of magnetic substrates having high thermal conductivity in order to prevent deterioration of heat releasing properties caused by low thermal conductivity when exothermic heat due to the core loss of the laminate of magnetic substrates comprising a magnetic metal thin plate and a high molecular compound is released to the outside. A laminate of magnetic substrates comprising a high molecular compound layer and a magnetic metal thin plate is used, wherein the volume resistivity defined in JIS H 0505 in a direction perpendicular to the high molecular compound layer surface of the laminate is less than 108 Ωcm. The laminate is provided with an electrical continuity point created among magnetic metal thin plates such that the high molecular compound inside the laminate is pushed out to the outside of the laminate by pressurizing the laminate.

摘要:
An electrostatic actuator comprises first and second stator sections having a first electrode array arranged in a first direction, and a second electrode array of electrodes extending in the first direction, respectively. A movable section having fifth and sixth electrodes arranged to face the first and second electrode arrays, respectively, is arranged between the first and second stator sections. A driving circuit alternately performs a first driving operation in which a DC voltage is applied between the adjacent electrodes of the first electrode array and a second driving operation in which a DC voltage is applied between the electrodes of the second electrode array. The voltage application is successively performed by deviating the positions of the electrodes to which the voltage is applied so as to move the movable section in the first direction while vibrating the movable section between the first and second stator sections.
