A display unit includes; a display panel, and a receptacle including of a plurality of sidewalls configured to receive the display panel, the receptacle including at least one joining projection disposed on at least one of the sidewalls, at least one joining groove formed on at least one of the sidewalls, wherein the at least one joining projection and the at least one groove are disposed on opposing sidewalls of the receptacle in substantially symmetrical positions with respect to a center line of the receptacle.

A disk clamp for clamping a number of magnetic hard disks within a disk drive has a plurality of balance weight holes and a coined index mark for use as a reference in balancing the hard disks after assembly. The disk clamp also has a coined profile located adjacent or around the balance weight holes in order to provide uniform circumferential clamp force by the disk clamp. The disk clamp has a profile that places the inner region of the disk clamp in the plastic deformation region at a certain specified clamping force at the center of the disk clamp.

The invention provides a wall surface aluminum plate system and an installing method thereof, wherein the wall surface aluminum plate system is arranged on a wall surface, and comprises a postpositive embedded plate, a vertical keel, a transverse keel, a plurality of F-shaped corner connectors and an arc-shaped aluminum plate, wherein the postpositive embedded plate is fixedly connected with the wall surface; the vertical keel is arranged on the postpositive embedded plate; the transverse keel is in an arc shape and is transversely arranged on the vertical keel; the F-shaped corner connectors are arranged on the arc-shaped surface of the transverse keel in a scattered way; the arc-shaped aluminum plate is matched with the shape of the transverse keel; the upper end and the lower end of the arc-shaped aluminum plate are respectively arranged in the F-shaped corner connectors. The wall surface aluminum plate system and the installing method of the wall surface aluminum plate system provided by the invention have the advantages that the upper and lower folding edges of the aluminum plate are made into reverse hook structures; meanwhile, the F-shaped corner connectors are designed; the upper strip edge of the aluminum plate is hung, and the lower strip edge inserter of the aluminum plate is inserted, so that the seam sealing by using a buckle plate is not needed after the installation of the arc-shaped aluminum plate is completed; the flatness and the aluminum plate connecting seam size are uniform; the appearance is attractive.
