Abstract: A method of manufacturing a unit cell having a negative electrode, a separator, and a positive electrode are stacked and placed between guide rollers. One of the positive electrode and the negative electrode. The separator is coated with a binder, and the separator is dipped in a solvent to soften a cured binder before the separator is put between the guide rollers. An apparatus for manufacturing a unit cell includes a reservoir in which at least two or more transfer rollers that rotate while the separator passes therethrough are mounted, and a solvent is stored at a predetermined level; and a chamber into which the separator passing through a reservoir is put together with the positive electrode and the negative electrode. Guide rollers are disposed so that the negative electrode and the positive electrode move to both surfaces of the separator, respectively.

Abstract: A fuzzy controller controls a track seeking operation and a track following operation for an actuator in accordance with a position error between a present position value and a reference value. When the actuator is in track seeking operation, the actuator is accelerated or decelerated based on a velocity error value between an actual velocity value of the actuator and a target velocity value determined from a velocity profile according to the position error. In a deceleration control of the actuator, a fuzzy inference value generated based on the velocity error value and its differentiated velocity error value is used for a control of the actuator, thereby reducing an occurrence of overshooting at a target track.
