摘要:
The composite oxide and the composite oxide carrier are manufactured by the precursor forming step and firing step. The precursor forming step includes high speed mixing means. The composite oxide catalyst is obtained by preparing a composite of catalytic components simultaneously with the formation of the precursor of composite oxide in the step of forming the precursor of composite oxide. The composite oxide and the composite oxide carrier are composed of a composite oxide in which at least one of cerium and zirconium, and aluminium disperse with extremely high homogeneity. With this structure, the heat resistance of the carrier is improved and consequently, enlargement of particles of the composite oxide defining the carrier, and sintering of adjacent particles of the composite oxide can be restrained, whereby the catalyst using the composite oxide carrier in accordance with the present invention is excellent in heat resistance. With the present invention, the carrier is not limited to a general catalyst carrier. The carrier may be interpreted to indicate general formed bodies. For example, the carrier with the present invention can be also used as materials for sensors and electrodes, optical materials, semiconductors and structure materials. Furthermore, the carrier can be used for a three-way catalyst, NOx catalyst or oxidation catalyst or a part thereof, and a promoter.

An estimated-SN(Signal Noise)-ratio is calculated for a time-series feature vector of noise-superimposed speech by using a noise-free speech model and a noise model. A noise-superimposed model is generated based on the estimated-SN-ratio. A likelihood between the time-series feature vector of noise-superimposed speech and the noise-superimposed model is calculated to obtain likelihood information. A noise spectrum included in the noise-superimposed speech is estimated from the likelihood information.

An image forming apparatus includes an image forming unit for forming images onto sheets in either one of a first mode for sequentially forming the images onto the sheets from a last page and a second mode for sequentially forming the images onto the sheets from a front page. The apparatus also includes a rotation processing unit for rotating the image in the direction of 180.degree. for the direction of the image in the first mode before the image forming unit forms the images in the second mode. The apparatus further includes a tray for stacking the sheets, a reversing path for reversing the sheet in the second mode, a conveying path for conveying the sheets formed with the images by the image forming unit to the tray directly or through the reversing path, and a stapler for performing a stapling on an upstream side in the conveying direction in the sheet and on a left side or a right side in the conveying direction. The stapler performs the stapling on the left side in the conveying direction in the first mode and on the right side in the conveying direction in the second mode.

A catalyst 1 is provided in a gas passage 4 for communicating between a gas flow-in unit 12 and a gas flow-out unit 13, and the catalyst 1 is heated by a heater 2, and a temperature sensor 3 for detecting the temperature of the heater 2 is provided inside the heater 2. By feeding power to the heater 2, the wall temperature of the heater 2 is raised to heat the catalyst 1, and then malodorous gas containing odor substances is passed in from the gas flow-in unit 12. The malodorous gas passes through the catalyst 1 in the gas passage 4 to be oxidized to be harmless and odorless, and is discharged from the gas flow-out unit 13.

摘要:
Disclosed is a parallel filtering circuit comprising at least two filters of a depth layer filtering type connected in parallel to each other in conduits showing different fluid resistances respectively, whereby, even when both the filters are clogged with particles of contaminants, the total flow rate may not decrease sharply, so that a preventive measure can be immediately taken before a fatal situation occurs. An orifice may be connected at its inlet to the outlet of the conduit having a smaller fluid resistance and at its outlet to the outlet of the conduit having a having fluid resistance.
