    摘要: A thermosetting synthetic resin composition consisting mainly of, for example, an epoxy resin is melted at a temperature of 70.degree. to 130.degree. C. After adding a filler to the resin composition, the resultant mixture is kneaded and rapidly cooled. The composition consists of a thixotropy agent, a leveling agent, etc., in addition to the epoxy resin and a curing agent for the epoxy resin. Aluminum as the filler is added in the amount of 30 wt % to 100 wt % of the mixture. The mixture of the composition with the filler is kneaded and rapidly cooled and is then pulverized to prepare a powder. The powder coating thus obtained is coated on a coil and is cured to provide a heat radiating insulator.

    摘要: Inverse distribution operations are performed on a large distributed parallel database comprising a plurality of distributed data segments to determine a data value at a predetermined percentile of a sorted dataset formed on one segment. Data elements from across the segments may be first grouped, either by partitioning keys or by hashing, the groups are sorted into a predetermined order, and data values corresponding to the desired percentile are picked up at a row location of the corresponding data element of each group. For a global dataset that is spread across the database segments, a local sort of data elements is performed on each segment, and the data elements from the local sorts are streamed in overall sorted order to one segment to form the sorted dataset.
