    摘要： The present invention provides a multilayered chip capacitor (MLCC) comprising internal electrodes and external electrodes formed to be perpendicular to the internal electrodes, whereby parasitic capacitance is reduced, resulting in no parallel resonance frequency effects. In addition, the MLCC has a capacitor structure, which provides a first surface and a second surface formed in a stacking direction of the dielectric layers in the capacitor body as a top surface and a bottom surface. Hence, in the thin capacitors having the same size, the number of internal electrode layers is increased, thereby reducing the ESR and ESL. Further, the PCB having an embedded MLCC is easily manufactured.

    摘要： A route searching method in a navigation system for searching a route from a starting point to a destination and calculating a route low in aggregate cost in consideration of cost per section. The method includes designating a preferable transit region and establishing a cost of the preferable transit region. Only an approximate transit region on a map can be designated and the route can be searched and calculated, whereby the user does not need to accurately designate a preferable transit route.

    摘要： In a multilayered ceramic capacitor, the width of an exposed portion of an internal electrode is reduced to be narrower than that of a non-exposed portion thereof. A dummy electrode that is not electrically connected to the internal electrode is formed to be connected to an external electrode. Deterioration of reliability due to penetration of the plating solution thereby is prevented and reduction in adhesion of the external electrode due to reduction in width of the exposed portion of the internal electrode is supplemented through mechanical connection between the external electrode and the dummy electrode.
