Abstract: A space-saving slide cover lifting structure consisting of a pair hinges, a pair of sliding rail holders, a pair of plastic slide guides, a pair of sliding rails, a pair of gears and a pair of gear racks is disclosed. The gear racks are respectively accommodated in the sliding rails to reduce space occupation, minimizing the width of the assembly of the gear rack and the respective sliding rail. The arrangement of the plastic slide guides prohibits direction contact between the metal sliding rails and the sliding rail holders, avoiding friction noise.

Abstract: Used in an electronic device comprising a cover panel and a base member, a slide cover mounting structure includes two hinges bilaterally mounted on the top wall of the base member, two sliding rail holders respectively connected to the pivot shafts of the hinges, two sliding rails bilaterally mounted on the bottom surface of the cover panel and respectively slidably coupled to a sliding groove on each of the sliding rail holder, two gears pivotally connected between fixed rails on the sliding rail holders, and two gear racks respectively mounted on the cover panel and meshed with the gears. Thus, the cover panel is prohibited from biasing during sliding movement, and turnable about the pivot shafts of the hinges from a horizontal position to a tilted position relative to the base member.

Abstract: This invention relates to a process for forming a lubricant layer of differing thickness on distinct zones of a maonetic disk of a hard disk drive without heating, inert gas plasma and UV-radiation or E-beam exposition. According to the present invention. an overcoat layer with distinct zones of differing thickness is first sputtered on the disk surface by using distinct masks under different sputtering conditions. A lubricant layer is then uniformly coated on the overcoat layer. Since a part of lubricant is bonded to the overcoat to form a bonded lubricant layer and the thickness of the bonded lubricant layer relates to the overcoat layer's property, a free lubricant layer with zoned thickness is consequently formed, which the free lubricant layer consists of the leftover lubricant. The zoned lubricant layer of the invention hence decreases the flying stiction.
