Abstract: A pivot structure includes a base, a bracket, an elastic component, and a positioning assembly. The bracket is rotatably connected to the base. The elastic component is disposed on the base. The positioning assembly includes an elastic clip and a pillar. The elastic clip is pivoted to the base and has a first releasing segment and a first positioning segment. The pillar is connected to the bracket and has a second positioning segment. The pillar is rotatably clipped in the elastic clip. The bracket is adapted to be expanded to a first expanding state through an elastic force of the elastic component, so as to drive the second positioning segment to move along the first releasing segment. The bracket is adapted to receive an external force to be further expanded to a second expanding state, so as to drive the second positioning segment to move to the first positioning segment.

Abstract: A pivot structure assembly including a fixed cover and a hinge module is provided. The hinge module includes a torque element, a first shaft, a second shaft, a first bracket and a second bracket. The torque element is fixed on the fixed cover and has a first and a second axle sleeves, parallely disposed at two opposite sides of the torque element. The first shaft is disposed through the first axle sleeve, and the second shaft is disposed through the second axle sleeve. The first bracket is pivotally disposed on the torque element through the first shaft, and the second bracket pivotally disposed on the torque element through the second shaft. When the first and second brackets rotate relatively to the torque element, the first and second axle sleeves respectively provide different friction forces to the first and second shafts. In addition, an electronic device is also mentioned.

Abstract: A pivot structure includes a base, a bracket, an elastic member and a positioning assembly. The bracket is rotatably connected to the base. The elastic member is disposed on the base. The positioning assembly includes a linkage member and a sleeve. The linkage member is pivoted to the bracket and has a positioning portion. The sleeve is pivoted to the base. The sleeve is fitted around the linkage member and has a releasing segment and a positioning segment. The bracket is adapted to be expanded to a first expanding state relative to the base by the elastic force of the elastic member, so as to drive the positioning portion to move along the releasing segment. The bracket is adapted to receive an external force to be continually expanded to a second expanding state relative to the base, so as to drive the positioning portion to move to the positioning segment.

Abstract: An electronic device includes a first body, a second body, a first pivot structure, a second pivot structure, and a locking structure not in contact with the second pivot structure. The second pivot structure is pivoted to the first body along a first axis through the first pivot structure. The second body is pivoted to the first pivot structure along a second axis through the second pivot structure. When the second body is unfolded to an open position along the first axis, the first pivot structure drives the locking structure to go to an unlocked state, and the second body is adapted to rotate along the second axis. When the second body is folded or unfolded to other positions along the first axis, the first pivot structure drives the locking structure to go to a locked state, and the locking structure stops the second body rotating along the second axis.

Abstract: A hinge structure includes a first shaft, a second shaft, a pivot base and a position-limiting mechanism. The first and second shafts are pivoted on the pivot base. The position-limiting mechanism includes a first position-limiting portion, a second position-limiting portion and a position-limiting component.

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.
