In a user equipment, a handover from a macro cell base station to a CSG cell base station is controlled based on a result of comparison between reception quality from the eNB and reception quality from the HeNB located in a macro cell. The planar magnetic inductor comprises an insulating oxide magnetic layer formed on a substrate, a conductive coil separated from a lower surface of the insulating oxide magnetic layer while being completely embedded in the insulating oxide magnetic layer, and a cover layer formed on the insulating oxide magnetic layer for protecting the insulating oxide magnetic layer. In some embodiments, the vibration damping system may be applied to pressure relief valves. By so doing, even when the terminal junction area and distance between terminal junctions in the terminal assembly portions are small, it is possible to increase the joint strength of the terminals, and also secure withstand voltage. The distance is also configured such that as bottles back-up, waiting for free channel gaps, the arm allows any buckling bottles to pass over and back onto the plate, rather than into the channel. An embodiment comprises a post-passivation layer that is larger than an overlying underbump metallization.
