Abstract: In generating inspection logic of a new component, the image of a new component is obtained, the trend data for selected characteristics of the focused region of the new component is computed; a previously inspected component having characteristics similar to that of the new component is selected by comparing the trend data of the new component with trend data of the previously inspected component, the image of the selected (previously inspected) component is read from the storage device, and inspection logic for the new component is generated using the images of the new component and images of the previously inspected component as teaching data.

Abstract: A PC board inspecting method capable of detecting deviation of an IC component at high speed with small storage capacity utilizes inspection logic particular to a component to be inspected. The inspection logic includes a color condition for specifying a color appearing in the body of the component to be inspected. The component is radiated with a plurality of color rays at different angles of incidence. An image formed by reflection light of the color rays is captured, and an inspection image including at least part of an edge of the body of the component to be inspected is captured. By using the color condition, a component body area satisfying the color condition is extracted from the inspection image by an image process.

Abstract: An method for creating an FMEA sheet includes the steps of, retrieving a plurality of documents, dividing words in each of the plurality of retrieved documents into a plurality of morpheme words by morphological analysis, calculating a co-occurrence frequency of each of the plurality of morpheme words, generating a co-occurrence frequency network with morpheme words having a greater co-occurrence frequency than a predetermined level in the plurality of morpheme words, grouping the plurality of documents using the co-occurrence frequency network, extracting a word same as an FMEA word registered in an FMEA word concept dictionary created in advance from each of the plurality of documents belonging to a same group as a word to be used in creating the FMEA sheet and substituting the extracted word to the FMEA sheet.

Abstract: A precedent database is generated by registering location indicating information that shows location of each of a plurality of precedent data. A knowledge database is generated by repeating processes of carrying out a search of this precedent database according to a specified condition formula and registering knowledge names representing results of the search in correlation with the condition formula. Component and failure names in the knowledge database are inserted as items of a generated FMEA sheet. Items of the FMEA sheet are specified and displayed such that corresponding text data can be referenced.

Abstract: Reference data for automatically inspecting shapes of fillets formed on a substrate are set to an inspection device that illuminates the substrate from specified directions to generate an image. For each type of components mounted to the substrate, a database is prepared, registering sets of reference data corresponding to different fillet shapes in correlation with heights of solder for forming fillets having these shapes. After components to be an object of inspection are identified, specified steps are carried out on each of these components, including the step of obtaining data on the height of solder for forming the fillet related to a land for which a target area for inspection has been set and reading out reference data corresponding to the data obtained from the reference data registered in the database.

Abstract: A fault management apparatus that enables calculation of evaluation values relating to a fault occurring to a management target as objective values without involvement of human judgment is provided. Fault information containing fault content information showing content of a fault occurring to a process in a production line, and detection status information and action content information associated with the fault is stored in a fault occurrence history storage part as a fault occurrence history. A fault extraction part reads the fault occurrence history from the fault occurrence history storage part to extract fault information containing specific fault content information. An influence degree calculation part calculates a degree of influence showing the degree of influence caused by a specific fault by performing statistical processing based on detection status information and action content information contained in the fault information extracted by the fault extraction part.

Abstract: For each teaching image, a plurality of patterns of color pickup regions each include a first region for picking up a color of a first part and a second region for picking up a color of a second part are set, the color of each pixel in the first region and the color of each pixel in the second region are mapped as a target point and an exclusion point respectively, to a color space for each of the patterns of the color pickup regions, a degree in separation between a target point distribution and an exclusion point distribution in the color space is calculated for each of the patterns of the color pickup regions, a pattern of a color pickup region having a maximum degree in separation is selected, a color range which divides the color space and has the largest difference between the number of target points and the number of exclusion points in the selected pattern therein is found, and the found color range is set as a color condition used in a board inspecting process.

Abstract: A technology is provided for automatically producing an inspection logic to be used in the action of inspecting a PC board. An inspection logic setting apparatus is arranged for acquiring a plurality of first images of components to be detected by the inspection and a plurality of second images of components to be rejected by the inspection, dividing each first and second images into the plurality of blocks, calculating a color distance between the plurality of first images and the plurality of second images in each block, selecting one or more blocks from the plurality of blocks which are relatively greater in the color distance, and assigning the selected block(s) to an area condition.

Abstract: A wheel structure for vehicles, capable of reducing a columnar resonance sound occurring in a wheel during a travel of a vehicle. A cross-sectional shape of a closed space defined by a wheel and a tire is varied in the circumferential direction so that a columnar resonance frequency in the closed space varies with a rotation of a wheel unit.
