  • Patent number: 10561976
    Abstract: A carbon dioxide capturing apparatus and process uses a self-generating power means that uses carbon dioxide in combustion exhaust gas through the convergence of a carbon dioxide absorption tower. The capturing apparatus and process also relies on ionic generator associated technology using a concentration difference between seawater and freshwater. The capturing apparatus and process result in increased production efficiency for electric energy and reduced costs for a carbon dioxide capturing process by increasing a concentration difference using an absorbent liquid for absorbing carbon dioxide and, at the same time, electricity is obtained through carbon dioxide which is a greenhouse gas.
    Type: Grant

  • Patent number: 5883749
    Abstract: An hard disk drive (a HDD) initialization technique, for performing compensation for an offset value of an IC (integrated circuit) of a PCB (printed circuit board), generated in associated circuits or apparatus, to stably initialize a head by calibrating an initial offset value to calibrate an integrated circuit offset value of a printed circuit board upon the power being applied; unlatching a head by using the circuit offset value; performing a full track seek for a given time period and calibrating a first torque constant as a self diagnosis function of an actuator; calibrating a bias value from servo information detected during the track seek; and performing the full track seek after calibration of the bias value and calibrating a second final torque constant so as to calibrate the torque constant of the actuator.

  • Patent number: 5828516
    Abstract: A servo control method of a disk recording system for detecting position of a head using a digital servo control method in which a disk contains an embedded burst recording region comprising four servo bursts. The servo control method contemplates on reading track identification information and servo burst information on the disk recording medium, determining whether a track on which the head is positioned is one of an odd and even track from the track identification information and the servo burst information, and generating an odd/even information bit and first and second position error signals in accordance with the determination; generating seek information from addition/subtraction to and from the odd/even information bit and the first and second position error signals; and correcting the track identification information in correspondence with the seek information and outputting a current position error signal.

  • Patent number: 5773948
    Abstract: A servo control method of a disk recording system enhanced with a servo control gain correction method. In a disk recording system for reading and writing information upon a disk recording medium by driving an actuator, the system contemplates supplying a given reference current to the actuator and calibrating a current moving distance of the actuator on the disk recording medium while it is rotated at a constant speed during a reference time, obtaining a distance difference between a given reference moving distance and the current moving distance, and obtaining a correction gain of the actuator in proportion to a given reference direct current gain value from the distance difference. The actuator is then driven in correspondence to the correction gain upon moving a head to a desired target position to read or write data on the disk recording medium.
