Abstract: In an optical/electrical hybrid substrate 10 including a wiring board 11 having a wiring and a via, and an optical waveguide 12 including an optical waveguide body 80 having a first clad layer 81, a second clad layer 83 and a core portion 82 disposed between the first clad layer 81 and the second clad layer 83 and provided on the wiring board 11, and a pair of mirrors 88 and 89 for reflecting a light signal, a first wiring pattern 96 for electrically connecting a terminal 117 of a light emitting device 13 for irradiating the light signal to the wiring and via, and a second wiring pattern 97 for electrically connecting a terminal 119 of a light receiving device 14 for receiving the light signal to the wiring and via, the first and second wiring patterns 96 and 97 are disposed in the optical waveguide body 80.

Abstract: An optical waveguide includes an optical waveguide main body and mirrors. The optical waveguide main body includes a first cladding layer, a second cladding layer and a core portion provided between the first cladding layer and the second cladding layer. The optical waveguide main body has a first region in which the core portion and the mirrors are arranged and the light signal is transmitted, and a second region arranged on both sides of the first region and not contributing to a transmission of a light signal. Through vias that pass through the optical waveguide main body is provided in the second region. The first region on a side that faces the light emitting element or the light receiving element is protruded larger than the second region on a side that faces the light emitting element or the light receiving element.

Abstract: This audio apparatus includes: a property data obtain device which obtains a property data appended to music data on playing; a command generation device which generates specific commands for each of operation devices; a command registration device which registers the commands generated by the command generation device, to a database when the operation devices have been operated for equal to or more than a predetermined time, so as to correspond to the property data appended to the music data on playing; and a property data search device which searches the command generated by the command generation device when the operation devices are operated for less than the predetermined time, searches the property data that corresponds to the command, and transfer the found property data to the external storage terminal device.

Abstract: When an input vocabulary is stored in advance in a pronunciation dictionary unit, a phoneme sequence correlated with the input vocabulary is acquired from the pronunciation dictionary unit and a dictionary code indicating that the acquisition source is the pronunciation dictionary unit is generated. When the input vocabulary is not stored in advance in the pronunciation dictionary unit, a phoneme sequence of the input vocabulary is generated by a pronunciation generation unit and a generation code indicating that the acquisition source is the pronunciation generation unit is generated. Then, a recognition grammar model in which the phoneme sequence of the input vocabulary is correlated with the dictionary code or the generation code of the input vocabulary is stored and a recognition parameter is generated.

Abstract: The invention provides an exhaust gas treatment agent characterized in that it comprises calcium silicate hydrate particles having a mean particle diameter of 0.2 to 4 &mgr;m and a specific surface area of not less than 60 m2/g and calcium hydroxide particles having a mean particle diameter of not more than 4 &mgr;m and the content of calcium hydroxide particles in both particle components is within the range of 20 to 60% by weight; a method of producing the exhaust gas treatment agent; and a process for the treatment of exhaust gases and soot and dust which uses the exhaust gas treatment agent.

Abstract: A sound signal processing method includes emphasizing a first sound signal based on a plurality of sound signals produced by a plurality of microphones arranged at intervals, determining a frequency by an arrival direction of a second sound signal other than the first sound signal and the interval between the microphones, and removing a frequency band including the frequency determined, from the first sound signal emphasized.

Abstract: The present invention relates to an improvement in cement for use in concrete of high strength and high flowability, mass concrete, shrinkage compensating concrete or concrete of high resistibility which are employed in the field of engineering and architecture or as building material through incremental launching method or wet formation. When the ratio of Al2O3 to Fe2O3 is regulated to a value of 0.05 to 0.62, the strength of concrete of high strength and high flowability can further be improved, and heat of hydration can be prevented, while improving the flowability of cement and maintaining a long-term strength thereof.
