Therein, E is the energy of a capacitor and Ecoul=Q2/2 Ccoul=Q2d/(2 ?0 ?x A), A is the area of the capacitor electrodes, d is the distance and ?0?x the dielectric constant between them. Ecorr describes the correlation energy, Ekin the electronic kinetic energy and Eexc the exchange energy of the electrode material.

  • Publication number: 20100039193
    Abstract: There is herein disclosed an interdigital capacitor, an inductor, and an LH transmission line and a coupler using the interdigital capacitor and the inductor. The interdigital capacitor comprises two finger sets which are substantially disposed in parallel with each other. Fingers of each finger set are overlapped at outer edges thereof with each other to thereby generate capacitance. The inductor is formed substantially spirally inside the transmission line, so that it can have a large inductance in a compact shape and can be used in a broad frequency band. The LH transmission line has a broad frequency band in a compact shape, which includes interdigital capacitors connected in series with each other and inductors connected in parallel with each other. In addition, the coupler employing the LH transmission line has an excellent couplability.

  • Publication number: 20100013568
    Abstract: Provided is a technology capable of reducing parasitic capacitance of a capacitor while reducing the space occupied by the capacitor. A stacked structure is obtained by forming, over a capacitor composed of a lower electrode, a capacitor insulating film and an intermediate electrode, another capacitor composed of the intermediate electrode, another capacitor insulating film and an upper electrode. Since the intermediate electrode has a step difference, each of the distance between the intermediate electrode and lower electrode and the distance between the intermediate electrode and upper electrode in a region other than the capacitor formation region becomes greater than that in the capacitor formation region. For example, the lower electrode is brought into direct contact with the capacitor insulating film in the capacitor formation region, while the lower electrode is not brought into direct contact with the capacitor insulating film in the region other than the capacitor formation region.

  • Publication number: 20090316329
    Abstract: A chip component having external electrodes that allow both connection by an interlayer connection conductor and connection by soldering and a component built-in module containing the chip component therein are produced and provided. A metal of electrode parts on at least one principal surface of the external electrodes at the ends of the chip component is different from a metal of electrode parts at the remaining portion of the external electrodes. With such a structure, both a metal suitable for connection to an interlayer connection conductor, such as a via hole conductor or a through hole conductor of the component built-in module and, a metal suitable for soldering can be used for the external electrodes. Thus, the component built-in module can be reduced in the height and size.

    Abstract: Capacitive deionization (CDI) is a non-membrane and chemical-free technique for water purification, used-water recycling, and seawater desalination. Ionic contaminants in the waters are retained by a static electric field built within the critical component of CDI, which is known as flow through capacitor (FTC). Apparently, parameters enhancing the field strength of FTC and electrode efficiency are the keys to the performance of CDI. The FTC of the present invention is formed by a plurality of monopolar and a plurality of bipolar electrodes, and a plural number of perforated holes are disposed on the FTC electrodes in a pattern that allows certain water flow rate and residence time to yield the highest efficiency of electrode utilization.
