20100044311 | METHOD AND APPARATUS FOR FURTHER PURIFYING ULTRAPURE WATER - Disclosed are a method for further purifying ultrapure water, according to which any impurities in ultrapure water can be stably removed to a high degree within a small space over a prolonged period; and an apparatus therefor. Ultrapure water introduced into an ultrapure-water purifying apparatus | 02-25-2010 |
20100096269 | ELECTRODEIONIZATION APPARATUS - An electrodeionization apparatus has a cathode and an anode, and has alternately formed therebetween concentrating chambers and desalination chambers by alternately arranging a plurality of anion exchange membranes and cation exchange membranes, each of the concentrating chambers being provided with a bipolar membrane to partition the interior of the concentrating chamber into a cathode side and an anode side, and each of the desalination chambers being divided into at least two layers including a first layer and a second layer, from an upstream side in a direction of flow of water to be treated, and being filled with an ion exchanger comprising an anion exchanger and a cation exchanger. The ion exchanger filling the first layer contains no less than 50 vol % of the cation exchanger, while the ion exchanger filling the second layer contains over 50 vol % to 80 vol % of the anion exchanger. As a result, the electrodeionization apparatus can be stably operated for a prolonged period of time while preventing formation of scale in the concentrating chambers and desalination chambers. | 04-22-2010 |
20110094963 | MEMBRANE SEPARATION METHOD AND MEMBRANE SEPARATION DEVICE - To provide a membrane separation method capable of attaining reduced adsorption of a membrane-fouling substance contained in treatment water onto the surface of a separation membrane during membrane separation of the treatment water, to thereby lead retarded deterioration in membrane separation performance, and a membrane separation apparatus for performing the method. In the membrane separation method, to treatment water, a particulate cationic polymer which swells in water but does not substantially dissolve therein is added, and the treatment water is subjected to membrane separation. | 04-28-2011 |
20110168626 | REVERSE OSMOSIS MEMBRANE, REVERSE OSMOSIS MEMBRANE APPARATUS, AND HYDROPHILIC TREATMENT METHOD FOR REVERSE OSMOSIS MEMBRANE - A reverse osmosis membrane that can maintain high permeability for a longer time, a reverse osmosis membrane apparatus, and a hydrophilic treatment method for a reverse osmosis membrane. A reverse osmosis membrane to which poly(vinyl alcohol) is absorbed, wherein the poly(vinyl alcohol) is an ionic poly(vinyl alcohol). Preferably, adsorption of a cationic PVA to the reverse osmosis membrane is followed by adsorption of an anionic PVA. More preferably, an ionic polymer other than PVA is also absorbed to the reverse osmosis membrane. A reverse osmosis membrane apparatus including the reverse osmosis membrane. A hydrophilic treatment method for a reverse osmosis membrane, involving bringing the reverse osmosis membrane into contact with an ionic poly(vinyl alcohol). | 07-14-2011 |
20110203977 | FILTRATION APPARATUS AND WATER TREATMENT APPARATUS - The filtration apparatus of the invention includes a filtration member | 08-25-2011 |
20120298570 | FILTRATION APPARATUS AND WATER TREATMENT APPARATUS - A filtration apparatus | 11-29-2012 |
20120330655 | VOICE RECOGNITION DEVICE - A voice recognition device includes a voice recognition dictionary in which a word which is recognized as a result of voice recognition on an inputted voice is registered, a reply voice data storage unit for storing recorded voice data about words registered in the voice recognition dictionary, a dialog control unit for, when a word registered in the voice recognition dictionary is recognized, acquiring recorded voice data corresponding to the word from the reply voice data storage unit, a reproduction noise reduction unit for carrying out a process of reducing noise included in the recorded voice data, an amplitude adjusting unit for adjusting an amplitude of the recorded voice data in which the noise has been reduced to a predetermined amplitude level, and a voice reproduction unit for reproducing a voice from the amplitude-adjusted recorded voice data. | 12-27-2012 |
20150019224 | VOICE SYNTHESIS DEVICE - A voice synthesis device according to the present invention regularly recognizes the contents of an utterance made by a passenger or the like, and specifies a word before abbreviation corresponding to an abbreviation included in a facility name or the like which is included in the utterance contents by using the facility name or the like. Therefore, the voice synthesis device can read the abbreviation out loud while preventing the passenger from being forced to perform a burdensome operation of, for example, registering the word before abbreviation corresponding to the abbreviation and using a reading method familiar to and appropriate for the passenger. | 01-15-2015 |
