Abstract:
PROBLEM TO BE SOLVED: To solve a problem occurring in an electrolytic capacitor type deionization technique, which is an energy-saving water purification method effective in reducing a total dissolved solid (TDS) wherein ions are adsorbed or desorbed by an electrode of a flow-through capacitor (FTC), the problem that the electrode performance is deteriorated due to microorganisms in water being a biofilm (slime etc.), contaminant gases or an oxide layer on the electrode, and to prevent and remove without interruption of the operation. SOLUTION: The method solves the problem at a low cost. The gas is discharged with a pump. The biofilm is sterilized immediately before the FTC treatment with electrolyzed ozone produced directly from the water to be treated, and then an adsorbed substance is removed by converting the polarity of the FTC electrode into an anode. When the FTC electrode is initialized, the water to be treated is inexpensively purified using no costly films nor chemicals at all. The generation of the biofilm is also prevented because the ozone is always produced in the FTC. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an electrode for oxidation which is low in price, high in current efficiency, suppressed in metal elusion and long in life in order to solve a problem that, in a conventional oxidation and sterilization technology used in ozone electrolysis, an electrolytic electrode for oxidation has been created through a trial and error process, the creation has been explained by an unreliable concept such as a "catalyst effect" which is unreliable in content, accordingly, a costly and unstable material is obligatorily used, furthermore, high current density is required, and thereby current efficiency has been lowered.SOLUTION: The electrolysis of water which generates ozone for oxidation is logically explained by a nanotechnology. There are found an effect that an oxide substance such as ozone can be generated by a tunnel effect of an insulation film which is arranged on the outside surface of an conductive base body of a positive electrode, and an effect that the oxide substance can be generated irrespective of the kind of a film substance as far as the insulation film is rigid and has a thickness of a nanosize. By using SUS430 stainless steel as a representative conductive base body, a passive film inherent to the stainless steel is used for the insulation film.

PROBLEM TO BE SOLVED: To supply a peak power and charge electricity simultaneously using a plurality of super capacitors and its elements in combination and to store the collected power. SOLUTION: The power transmission device stores energy in an efficient way using a plurality of super capacitors. To meet the demand, the device calculates the required power in real time and re-configure a system comprising the super capacitors according to the demand. Arrangement can be made in serial and in parallel, or in combination thereof to always achieve the most suitable one. A consistent, continuous supply of high voltage energy is stored and electricity is transmitted in a more efficient way as a compact system using a CD swing and reverse charge mechanism. This energy recovery utilizes nonpolar property of super capacitor element in forming an electrode as well as surface absorption of ion.

Abstract:
PROBLEM TO BE SOLVED: To solve the following problems: it is practically impossible to drive a high-voltage load unit operating at 12 volts or higher by using an electric double-layer capacitor (EDLC) singly because of low voltage per unit cell; the system connects multiple devices in series to achieve a required voltage and further requires a protective circuit, so that its weight, size, and cost increase; and there is a difficulty in manufacturing a cylindrical electrode because a metal sheet is cured by high-temperature treatment for evaporation of a carbon nanotube (CNT) film though a binder-free EDLC (requiring no binders) which directly evaporates CNTs is ideal. SOLUTION: Carbon nanotubes (CNTs), which have high specific surface area and high conductivity, are promising as a material for an electric double-layer capacitor (EDLC) having high energy density and a low ESR value. By using a stacking method, in which CNTs are directly evaporated onto an electrode and multiple sheets are stacked, a high voltage can be achieved without using a protective circuit. Furthermore, the high operating voltage EDLC can use a portion of a metal housing or the like of a load unit as an electrode of the EDLC, and can be incorporated in the load unit.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem that the conventional technique for water purification, which is carried out in various ways, mainly for example, a reverse osmosis method, ion-exchange method, and electrodialysis method, needs large-scale facilities consuming a large amount of chemicals and having no preparation of handy tools such as a module, even though it is essential for ideal water purification to have high performance at low cost, while much attention is paid to the environment, by building a bipolar FTC (flow-through capacitor) module comprising stacked high-performance electrode assemblies, thereby realizing the FTC module of high-performance at low cost, particularly low cost of maintenance. SOLUTION: The bipolar electrode can not only attain 100% efficiency for the FTC electrode, but also cost reduction for the FTC module preparation. By utilizing "energy exchange" between the two capacitors, which means a novel usage of the active carbon refreshing using the FTC module and a supercapacitor, the saturated FTC electrode can be refreshed rapidly with a minimum consumption of cleaning water.

It is desirable to distribute it as emergency goods for every citizen. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a self-contained integrated system for removing all harmful substances in water containing both ionized substances and neutral substances as water contaminants in a cost-effective and safe manner. SOLUTION: In order to conduct electric capacitive deionization (CDI), a filtration capacitor 6 is used to remove ionized contaminants in water while electrically neutral contaminants are passed through an electrolytic ozone generator 3 for decomposition. Upon ozone treatment, gaseous or ionized substances are produced. Upon a passage of the gaseous or ionized substances through CDI, the ionized substances are secondarily removed. An ozone/CDI composite technique of the electrolytic ozone generator 3 and the FTC capacitor 6 is an effective method for removing harmful substances in water, integrates ozone generation with the FTC capacitor in CDI and can realize water treatment with low-consumption energy and without secondary contamination.

Abstract:
PROBLEM TO BE SOLVED: To provide a load levelling technique with a primary battery side by which energy is recovered from discarded dry batteries. SOLUTION: A dry battery and a symmetrical super capacitor are combined and used to increase total energy. The series connection of the super capacitor and the dry battery allows the super capacitor to boost the voltage of the battery, and also can supply more current as compared with the series connection of only batteries. The super capacitor stores power while discharging power. As the super capacitor discharges to reduce voltage at one electrode, a negative potential is accumulated at the opposite electrode to compensate it. A control circuit repeatedly reverses the polarities at the opposite ends of the super capacitor to continuously recover more energy as compared with the dry batteries arranged in series, with the effective utilization and the reduction of the discarded dry batteries.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem of no contribution to performance of a capacitor in a case of a past conventional super capacitor, in which power transmission is intermittent because of only once of one peak power transmission and not practical to actual power application, and further only insufficient energy remains if the voltage is decreased to a threshold level or below and a load device cannot be driven even though the reaming energy is charged or discharged. SOLUTION: Electric power supply can be utilized efficiently by always optimizing charge and discharge. "CD swing" takes charge of switch, and for all steps, one group is under discharge, while another group is under charge/recharge. Two groups interchange the role of charge and discharge in the following cycle, and electricity demand will be fulfilled. The voltage and current are increased numbers of times by a super capacitor stored in a compact housing. The power is made to correspond in wide-range formation of voltage and current by system control. While efficient energy recovery can be performed, prompt power supply and power recovery of unrestricted number of times is realized. COPYRIGHT: (C)2008,JPO&INPIT
