Abstract: PURPOSE:To accurately realize linear drive with a degree of freedom of 2 for X axis and Y axis and also realize long-length stroke drive by providing a rectangular plate to be vibrated, an vibrator for generating the surface wave in both X-axis and Y-axis directions and a movable body plate which can be moved in each direction of X-axis and Y-axis. CONSTITUTION:A drive 11 is actuated to turn off the power source of a piezoelectric element provided against the Y-axis direction and to apply an AC voltage to a piezoelectric element provided against the X-axis direction. Thereby, elliptic vibration is generated on an rectangular vibrating plate to generate a surface wave which will become the travelling wave. With generation of this surface wave, a movable body 4 placed in contact with the vibrating plate moves in the X axis direction. Movement in the Y axis direction can also be made by changing over the driver 1. Thereby, movement in both X axis direction and Y axis direction can be realized with high accuracy and the linear drive in both directions ensure feeding of long length stroke by continuously supplying the travelling wave with the driver 1.

Abstract: PURPOSE: To reduce leakage flux, to improve the insulating function, to reduce the thickness of a device, and to improve the efficiency by providing an insulating layer made of a tape or an insulating film so as to be overlapped with a secondary winding, and winding a primary winding thereon. CONSTITUTION: A secondary winding 5 is wound around a bobbin 1 with a separator, and an insulating layer 6 is provided between the secondary winding 5 and a primary winding 7 wound thereon. In this case, the insulating layer 6 can be formed, for example, by winding a thin case made of resin or a tape. Since the primary winding 7 is wound on the insulating layer 6, breakdown voltage between the winding 5 and the bobbin is secured by the separator of the bobbin 1, and breakdown voltage between the winding 7 and the winding 5 is secured by the insulating layer 6, and the high breakdown voltage can be obtained. Namely, since the primary winding 7 and the secondary winding 5 are wound around the same shaft, almost all the magnetic flux interlinked with the winding 7 are interlinked with the winding 5 so as to remarkably reduce the leakage flux.  High breakdown voltage and the high insulating performance can be obtained, and the thickness of the device can be reduced, and the cost can be reduced, and efficiency and reliability of the device can be improved.
