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.

摘要： PROBLEM TO BE SOLVED: To prevent deformation caused by halation at the time of forming an upper magnetic film of an induction type magnetic head, and to reduce resistance by making a spiral coil diameter small.
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 remove only large quantities of hydrogen gas in an accident with a minimum addition of equipment by housing an alloy for storing hydrogen gas in a hydrogen gas storage box, arranging it one over another within a reactor containment vessel, and removing hydrogen gas by the hydrogen gas storage alloy if hydrogen gas is generated in the vessel. SOLUTION: The hydrogen gas generated within a reactor containment vessel 3 in an accident forms an ascending flow near a γ-shield 2 and a descending flow near the inside wall of the vessel 3 by the circulating force of a reactor containment vessel spray. In a sever accident, the ascending flow and descending flow are formed in the same manner. A hydrogen gas storage box 8 is arranged in a position laid along this gas flow, whereby hydrogen gas can be preferentially introduced into the box 8. Thus, hydrogen atom is freely carried in the clearance 11 of a hydrogen gas storage alloy 9 and a clearance 12 of shelf 7 of a support structure 6, penetrated into the hydrogen gas storage alloy 9 through the clearance of the grid of the hydrogen gas storage alloy 9, and absorbed.

摘要： PURPOSE: To simply check a connection state between switchboards without requiring manual operation by collecting path information by communication between the switchboards. CONSTITUTION: This communication system has a communication style applied to plural switchboards 1 to 4 between two subscribers A, B. The switchboard 1 receiving a communication path information collection request signal collects path information in its own switchboard 1 based on program data stored in its own switchboard. When a path to be collected is connected to another switchboard 2, the switchboard 1 transmits an information collection start request signal to the switchboard 2 and collects the communication path information of the other switchboard 2 by communication between the switchboards 1, 2. After receiving an information collection start checking signal, the switchboard 1 transmits an information collection request signal to request the collection of communication path information in the switchboards 3. After receiving an information collection result signal, the switchboard 1 refers to information indicating whether collected information is connected to other applied switchboards or not, and when the connection exists, transmits the information collection request signal again to collect the communication path information of the succeeding switchboard 4.

摘要： PURPOSE:To perform a smooth movement of a probe and to shorten a flaw finding time, by a method wherein a rotary body, having a crossing track on which a moving truck is delivered, and a stopper are installed at a point where a stationary track, installed at the exterior of a pressure container for a nuclear reactor, intersects a fixed track in a peripheral direction. CONSTITUTION:In case a moving truck 20 is transferred from a longitudinal track 24 to a peripheral track 25A, the truck 20 is moved from the longitudinal track 24A to a track part 26B of a cross-shaped track 26. Said positions can be detected by a photo sensor, not shown, mounted to a count dock 52 and the moving truck 20. If, with a chain 35 operated, a rotary disc 27 is turned until the track part 26D collides with a stopper 28 and the truck 20 is travelled, the truck 20 is transferred to the peripheral track 25A from the track part 26D. A reliable positioning can be performed by the stopper 38, and thereby the cross- shaped track 26 and the peripheral track 25A accurately coincide with each other.

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.
