The management computer 600 copies data in the volume 111 within the storage device 100A to the volume 115 within the storage device 100B. The barrier metal layer can be deposited directly on the gate dielectric layer. A method in accordance with the present invention further includes providing the operating velocity signal and operating current signal to a controller and establishing a target motor velocity. The exhaust-side control unit 7a sequentially generates a target air-fuel ratio KCMD to converge the output of the O2 sensor 6 to a target value using the estimated value, and manipulates the air-fuel ratio of the internal combustion engine 1. A stand is provided to support the portable external hard drive. More particularly, the present invention relates to an aircraft, missile, underwater vehicle or projectile with removable control surfaces.
