摘要： A method is described for finding correlation between a plurality of data having two kinds of numerical attributes and a true-false attribute. The method comprises the steps of: constituting a plane with two numerical attributes, dividing the plane into meshes, and counting the number of data in each mesh (also called a "bucket") and the number of data whose true-false attribute represents true. If each mesh is assumed to be a pixel, such plane can be considered as a plane image in which the number of data corresponds to brilliance, and the number of data whose true-false attribute represents true corresponds to saturation. The method further includes the step of segmenting an admissible image which is convex along an axis of the plane according to a predetermined condition .theta. to find an area with strong correlation. If the segmented area as the admissible image satisfies the above-described condition such as the maximized support rule, the method also presents the area to the user. In addition, necessary attributes for data included in the area are also extracted from a database, as required.

摘要： A method is disclosed for computing an association rule in a database having numerical attributes and 0-1 attributes. First, a numerical attribute is divided into a plurality of intervals (or buckets), and each data set is placed into a single bucket according to the value of the numerical attribute. The number of data sets in each bucket and the number of data sets with a 0-1 attribute being 1 are counted. Second, the starting bucket of an interval to be detected is to be detected. Third, the terminating bucket corresponding to the starting bucket is detected. That is, the largest interval with a confidence equal to or larger than a predetermined value. Fourth, one of the detected pairs of starting and terminating buckets which includes the largest number of customers is the answer to this question. Finally, the required data attributes of data included in this interval is subsequently retrieved.

摘要： A method is disclosed for determining the correlation among data sets having a numerical attribute and a 0-1 attribute. First, a numerical attribute is divided into a plurality of buckets, and each data set is placed into a single bucket according to the value of the numerical attribute. The number of data sets in each bucket and the number of data sets with a 0-1 attribute of 1 are counted. Second, an axis corresponding to the total number of data sets in a first through a particular buckets (X axis) and an axis corresponding to the total number of data sets with a 0-1 attribute of 1 in a first through a particular buckets (Y axis) are virtually established, and points corresponding to the respective values of the first through the particular buckets are virtually plotted. Third, after a plane is constructed in this manner, one of the pairs of points separated at an interval of T.times.N or T or larger which has the largest slope is found. This step is most important to fast processing, and this invention employs the nature of convex hulls to reduce the number of points to be considered. Finally, once this pair of points has been determined, the corresponding pair of buckets can be determined, resulting in the output of the corresponding segment. Also, once this process has been finished, the user can retrieve the required part of the data included in this section.

摘要： Heat radiation surfaces 7b and 8b of electrode lead frames 7 and 8 make thermal contact with heat radiation members 301 via insulation sheets 10 to dissipate heat from a power semiconductor element 5 to the heat radiation members (thick portions 301). Each of exposed areas of the heat radiation surfaces 7b and 8b and a surface 13b of a mold material (sealing material 13) adjacent to the exposed area produce an uneven step from which either one of the exposed area and the surface 13b adjacent to the exposed area projects. The step side surface formed between the convex surface and the concave surface of the uneven step has an inclined surface 7a or 13a so configured that an obtuse angle can be formed by the inclined surface and the convex surface and by the inclined surface and the concave surface for each.
