摘要： PROBLEM TO BE SOLVED: To provide a rotor of a rotating electric machine that makes the flux of permanent magnets hardly leak, in the rotor having a plurality of permanent magnets embedded inside a rotor iron core with the magnets constituting each pole divided by dividing pieces of the rotor iron core. SOLUTION: In the rotor 2 in which a plurality of permanent magnets 4 are embedded inside the rotor iron core 6 of a rotating permanent magnet electric machine and the magnets 4 that constitute each pole are divided by the dividing pieces 6c of the rotor iron core 6, the magnets 4 are formed in such a way that, as the outside circumference of each magnet 4 embedded in the rotor iron cores 6 approaches from it center in the circumferential direction to the dividing pieces 6c, the distance between the outside circumference of the magnets 4 and that of the rotor iron core becomes larger gradually. Because the magnets are hardly demagnetized since they are embedded and the outside circumferential part of the rotor iron core is thin though the magnets constituting each pole are divided by the dividing pieces, the outside circumferential part of the iron core is saturated, so that the leak of the flux of the permanent magnets is suppressed. As a result, the drop of the output of the rotating electric machine can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve convenience of a system in data management between plural databases by preventing generation of inconsistency caused by a difference in synchronous timing when synchronizing update processing. SOLUTION: In a synchronizing method between the databases, data update is managed in a main database, and updated data are synchronized to one or more sub databases. In the synchronizing method, the immediate or delayed synchronous timing is set, and the synchronous processing is executed according to the set conditions. By associating contents of required immediate processing with the updated data recorded in a log as delayed processing, synchronous data wherein the necessary updated data are lumped is generated, and the synchronous data is synchronized to the sub databases.
