  • Patent number: 10562013
    Abstract: This oxidation catalyst for diesel engines is divided into an upstream-side catalyst layer and a downstream-side inner catalyst layer in the flow direction of the exhaust gas, and a downstream-side outer catalyst layer is additionally formed so as to cover the surface of the downstream-side inner catalyst layer. The upstream-side catalyst layer and the downstream-side inner catalyst layer contain Pd, and the downstream-side outer catalyst layer contains Pt. The amounts of Pt and Pd contained in the upstream-side catalyst layer and the amounts of Pt and Pd contained in the downstream-side inner catalyst layer are constantly set to certain values, while the amount of Pt contained in the downstream-side outer catalyst layer is set to a value which enables the oxidation efficiency to be at a predetermined value or higher.

  • Patent number: 7831530
    Abstract: A method of the present invention is processed by a selector. The selector selects each member constituting a learning data set from a data set source. Each member of the source is feature data extracted through a transducer and assigned to any one of categories in advance. The selector calculates each member's divergence degree of the source to obtain an average divergence degree. If an output neuron of the output layer of a neural network is related to different categories of all the categories represented by the output layer, the selector includes every member of the source corresponding to the category of the minimum average divergence degree in the selection from the source to the learning data set. The selector also excludes, from the selection, every member of the source corresponding to every remaining category of the different categories.

  • Patent number: 7778947
    Abstract: An anomaly monitoring device includes two neural networks which are switchable between a training mode by using training samples and a checking mode for classifying, based on a training result, whether an amount of characteristics obtained by an operation of an apparatus indicates that the operation of an apparatus is normal and a mode switching unit controlling one of the neural networks to operate in training mode and the other neural network to operate in the checking mode. Further, the anomaly monitoring device includes a switching determining unit computing a judgment evaluation value serving to evaluate reliability of a judgment result of the other neural network operating in the checking mode, and for instructing the mode switching unit to have the one of the neural networks operate in the checking mode and the other neural network operate in training mode when the judgment evaluation value does not meet evaluation criteria.

  • Patent number: 7480410
    Abstract: An image recognizing method is provided, which includes the capability of efficiently recognizing characters such as letters and numerical characters included in an original image with accuracy when at least one of the characters is composed of plural elements. In this method, the elements in the original image are extracted to obtain a second image, in which each of the elements is enclosed by a rectangular frame. Then, a composite image is prepared with respect to a combination of the rectangular frames in the second image. After calculating a characteristic amount of the elements included in the composite image, the characteristic amount is input in a back-propagation network, in which learning about a reference character(s) to be included in the image has already finished, so that a degree of agreement between the characteristic amount of the composite image and the reference character is obtained.

  • Publication number: 20040247171
    Abstract: A method for appearance inspection utilizes a reference image and an object image. Before determining a final reference image for direct comparison with the object image, the outlines of the reference and object images are extracted and processed in accordance with an error function indicative of linear or quadric deformation of the object image in order to derive error parameters including a position, a rotation angle, and a scale of the object image relative to reference image. The resulting error parameters are applied to transform the reference outline. The step of updating the error parameters and transforming the reference outline is repeated until the updated error parameters satisfy a predetermined criterion with respect to a linear or quadric transformation factor of the object image. Thereafter, the last updated parameters are applied to transform the reference image into the final reference image for direct comparison with the object image.
