摘要： PROBLEM TO BE SOLVED: To reduce an operation management cost in a usual mode while maintaining the recovery of a deficit-free database and the online performance of a site. SOLUTION: A first system is comprised of a main storage 103 storing a DB (Data Base) 107 and a main computer 100 running a main DBMS (Data Base Management System) 101 providing the DB. A second system includes a sub storage 113 receiving the copy of a log indicative of the update difference of the DB 107 from the main storage 103 and storing a sub-DB 117, and a subset 500 recovering the sub-DB 117 based on the log copied from the main storage 103.

SOLUTION: A 1st spiral layer of a conductor coil 2a of Cu or the like is formed on a magnetic gap film 14 by a plating method. A 2nd spiral layer of a conductor coil 2b is formed thereon via an insulating film 4a. The 1st layer of the conductor coil 2a and the 2nd layer of the conductor coil 2b are jointed to each other at a contact part 3 in an inner circumferential part of the spirals and connected in series. SImultaneously with the formation of the 2nd layer of the conductor coil 2b, a dummy pattern (wall) 9 having almost as wide as the upper magnetic film 1 is formed between the contact part 3 and the rear end of the position where the upper magnetic film 1 is formed in the inner circumferential part of the spirals. Thereafter, the 2nd layer of the conductor coil 2b is covered with an insulating film 4b, and a plating substrate film 6 for forming the upper magnetic film 1 is formed on the insulating film 4b by sputtering or the like. A photo resist is applied on these laminated films, and a resist frame for forming the upper magnetic film 1 is formed by exposure.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor device that improves dv/dt-controllability via a gate drive circuit during turn-on switching while maintaining a low loss and a high breakdown voltage.
SOLUTION: In order to solve the problem, the semiconductor device has such a configuration that a gate electrode 401 is disposed on a sidewall of a wide trench 423. This allows gate parasitic capacitance to be small since the gate electrode 401 is covered with a gate insulating film 402 and a thick insulating film 403 to be an interlayer film, eliminates gate potential fluctuation so as to improve dv/dt-controllability for the absence of a floating p-type layer, and secures the low loss and low noise.

摘要： PROBLEM TO BE SOLVED: To reduce the pressure loss coefficient of an orifice of fuel support metal in a boiling water reactor without degrading reinforcement effects by a reinforcement beam of a core support structure plate having a perpendicular reinforcement beam to the utmost.
SOLUTION: Each of reinforcement beams 3 and 4 of the core support plate of a boiling water reactor is perpendicularly assembled and the thickness of one reinforcement beam 3 is formed thinner than the thickness of the other reinforcement beam 4. Because of the difference in thickness of each reinforcement beam 3, 4, flow areas S
1 and S
2 in the left and the right of the boundary of a broken line connecting a corner where the reinforcement beams 3, 4 cross and the center of the orifice 2 of the fuel support metal 1 facing the corner become imbalance. As the flow paths around a control rod guide tube 9 inserted between each reinforcement beam 3, 4 become asymmetric on the broken line, and the flow into the orifice 2 of the fuel support metal 1 is simplified, pressure loss in the reactor core is reduced.
