Abstract:
The present invention provides a fluorescent substance excellent in emission intensity and in emission efficiency. The substance can be excited by light at a longer wavelength than ever. The present invention also provides a luminous composition comprising the fluorescent substance and a light-emitting element using the substance. The fluorescent substance comprises a rare earth metal and a phosphine oxide ligand which coordinates to said rare earth metal and said ligand containing at least one siloxane bond in its structure. The fluorescent substance can be produced from a reaction between a compound having a siloxane bond and a rare earth complex coordinated by a phosphine oxide ligand. The luminous composition comprises the fluorescent substance.
Abstract:
A lighting device including a substrate (10), and at least three light emitting elements (11) mounted on the substrate, each having an upper light emitting surface in rectangular shape and side light emitting surfaces in rectangular shape. The light emitting elements are positioned to surround a light-gathering region (12) where the light emitting elements are not located, and one of the side light emitting surfaces of each light emitting element is directed to face approximately a central portion of the light-gathering region.
Abstract:
A fluorescent pattern forming article including a first layer containing a metal ion, and a second layer disposed facing the first layer and containing a ligand coordinating with the metal ion contained in the first layer to thereby enable an intensity of fluorescence based on the metal ion to be changed.
Abstract:
The present invention is characterized in that the car navigation system for, at the time of desiring map information, traffic information, and other required information in a car, inquiring an information distribution service provider for distribution the information is composed of a moving terminal device which can be operated by inputting and outputting voice, a communication device, an audio interactive server which can input and output voice and data, is connected to an external device and the Internet on the basis of audio interactions by the voice recognition process and voice synthesis process, and executes information transfer, and one or a plurality of information distribution service providers connected to the Internet for distributing information such as map information and traffic information.
Abstract:
Aqueous concentrate herbicidal compositions are provided comprising a herbicidally effective amount of ammonium salt of N-phosphonomethylglycine wherein the molar ratio of ammonia to N-phosphonomethylglycine provides a pH of about 6 to about 7, and a herbicidal efficacy enhancing amount of one or more surfactants. Compositions of the invention are storage-stable over a wide range of temperatures. Also provided is a method of killing or controlling vegetation comprising diluting a composition of the invention in water and applying the diluted composition to foliage of the vegetation.
Abstract:
A speech recognition apparatus has a speech input unit for inputting a speech; a speech analysis unit for analyzing the inputted speech to output the time series of a feature vector; a candidates selection unit for inputting the time series of a feature vector from the speech analysis unit to select a plurality of candidates of recognition result from the speech categories; and a discrimination processing unit for discriminating the selected candidates to obtain a final recognition result. The discrimination processing unit includes three components in the form of a pair generation unit for generating all of the two combinations of the n-number of candidates selected by said candidate selection unit, a pair discrimination unit for discriminating which of the candidates of the combinations is more certain for each of all .sub.n C.sub.2 -number of combinations (or pairs) on the basis of the extracted result of the acoustic feature intrinsic to each of said candidate speeches, and a final decision unit for collecting all the pair discrimination results obtained from the pair discrimination unit for each of all the .sub.n C.sub.2 -number of combinations (or pairs) to decide the final result. The pair discrimination unit handles the extracted result of the acoustic feature intrinsic to each of the candidate speeches as fuzzy information and accomplishes the discrimination processing on the basis of fuzzy logic algorithms, and the final decision unit accomplishes its collections on the basis of the fuzzy logic algorithms.
