Abstract: In the multi-layer inductor, all of the plurality of through conductors are not aligned in a straight line, and the distance between the through conductors can be sufficiently kept in the element body having a predetermined dimensional standard. Therefore, the through conductor as a heat source is apart from each other, and the heat of the through conductor can be efficiently radiated to the outside of the element body.

Abstract: In the multi-layer inductor, the internal electrode includes the auxiliary conductor, and the auxiliary conductor is jointed to the external electrode at the end face. Therefore, when a defect occurs in a part of the through conductors, a current flows through the remaining through conductor(s) and a current also flows through the auxiliary conductor. Therefore, overheating at the joint surface between the remaining through conductor(s) and the external electrode can be prevented, and cutting and/or fusion starting from the joint surface can be prevented.

Abstract: A base station includes an obtaining unit and an instructing unit. The obtaining unit obtains, from another base station that communicates with a mobile device, a propagation delay amount between the other base station and the mobile device. When a propagation delay amount between the base station and the mobile device which is based on the propagation delay amount obtained by the obtaining unit is present within a predetermined range from a boundary of a detecting window that is used in detecting a preamble sequence transmitted from the mobile device, the instructing unit instructs the mobile device to stop the transmission of the preamble sequence corresponding to another detecting window that lies adjacent across the boundary.

Abstract: A CDMA receiver for detecting paths of a direct incoming wave and a delayed incoming wave corresponding to the same channel from a receiving signal and combining the detected signals of a plurality of paths. A searcher unit operating in a first mode in a first search time range and in a second mode in a second search time range, which is narrower than the first search time range, and detecting the paths of the direct incoming wave and the delayed incoming wave in the first mode or in the second mode. A finger unit for inversely diffusing the signals of the paths detected with the searcher unit, combining a plurality of signals inversely diffused and detecting whether synchronization of the combined signal is set up or not. The searcher unit operates in the first mode at the start of channel signal reception and in the second mode after switching from the first mode while synchronization of the combined signal is detected.
