The present invention relates to a system and method of data restoration, for instance, after the occurrence of a user error. This allows the driver to drive the vehicle so that the guide line will not overlap the image of another vehicle thus allowing parking that avoids any contact. Water in contact with the bottom layer is rapidly absorbed in the hygroscopicity polymers by a water-repellenting layer, so that water is transferred in one direction. Namely, the SRAM cell 1 is designed in such a manner that W2=W3=W4, and L2=L3=L4. The positioning unit contacts the leading end of the object that has entered the space and positions the object in the transport direction when the holding unit moves to hold the object. The pharmacological test results indicated that the compound could remarkably increase the level of NE, 5-HT and HAV in the brains of model rats having depressive disorders, remarkably enhance tremors induced by 5-hydroxytryptophan and behavioral effects induced by levodopa, and inhibit the re-uptake of 5-HT and NA.
