Title: Unlatching method for hard disc driver
Inventor: PARK SEONG YEOL

Abstract: PURPOSE: An unlatching method for an HDD(Hard Disk Drive) is provided for the drive to be in a standby state without causing a damage to the drive in replacing a head from a parking zone to a data zone. CONSTITUTION: An initial current applied to an initial VCM(Voice Coil Motor) is read for checking detection of Fsync, FGray, FGrsync. In case of detecting Fsync or FGray, input of the VCM(Voice Coil Motor) is waited. In case of detection of FGrsync, output is increased. If there is no detected signal, a control data is outputted for detecting a target track. In case of detection of the target track, a standby state for a driving is performed. Otherwise, the detection of the target track is continuously performed.

Title: Making method of hgih strength composition aluminium material
Inventor: BAEK KYONG-HO
Filed: 1992-12-30
Granted: 1995-03-28
Abstract: The aluminum-based composite was manufactured by reinforcing the composite with metal-coated alumina short fiber. The alumina fiber coated with metal by the sol-gel method was processed to preform, in which aluminum flux was impregrated by pressing for manufacturing aluminum composite. The metal-coated alumina fiber was treated at 300-1400≰C for 30min-1hr in the over 10-5 torr vacuum atmosphere. The metal coat of alumina short fiber was formed by dipping the fiber in sol solution which was manufactured by solving the metal acetate compound such as Co, Ni or Cr in ethyl alcohol and adding the dehydrated water and acid to solution.
