Abstract: A removable hard drive storage device comprises: a housing having a first and second partition board each formed with a plurality of guiding grooves; a plurality of hard drive casings accommodated between the first and second partition boards. Each of the hard drive casings has a first side plate and a second side plate whose surfaces are each formed with a plurality of guiding units slidably disposed in the guiding grooves. Upper ends of the first and second side plates are each formed with an expansion unit for engaging the upper edges of the first and second partition boards, fixing the hard drive casing at a raised position in the accommodating space. Through the above structure, the hard drive casing can be fixed at the raised position in the accommodating space without separating from the housing for facilitating replacement of the hard drive and without using screws.

Abstract: A removable hard disk drive holder made of a plastic unit enveloping a metallic unit comprises a bracket, a plate and a handle. The bracket has a front panel and two side plates. The two side plates extend toward the same direction perpendicularly from the opposite edge of the front panel. The front panel has a front panel pivot portion arranged over one edge thereof. The plate slidably engages with the front panel and has a latch fastening portion. The handle has a handle pivot portion and the handle fastening portion conforming to the latch fastening portion. The handle pivot portion is arranged over one edge of the handle and pivotally connected to the front panel pivot portion. The removable hard disk drive is structurally firm, light and thin and minimizing associated members.

Abstract: A collapsible cable management arm is foldable with a plurality of heat dissipation apertures. The collapsible cable management arm includes a plurality of racks pivotally connected together which gives a zigzag chain structure being retractable. The rack is formed by a primary and a secondary plate. The secondary plate resembles the size and shape of the primary plate. The secondary plate slides into the tray-like primary plate to form the individual rack with hollow compartment there-between. The thickness of the rack arises from a primary positioning portion of the primary plate. The hollow compartment is further divided into connection and cable compartments by at least one pair of primary and secondary partitions.

Abstract: A base assembly includes a base plate, a pull-release handle, an extension member, a pivoting member, a cover plate and a latch member. The pull-release handle has a handle portion and defines a handle opening. The pull-release handle and the extension member are reciprocable in parallelism with a pulling direction on the base plate. The pivoting member has a force-receiving end and a force-transmitting end. The force-transmitting end is movable by the force-receiving end. The latch member has a locking strip and at least one locking portion. The force-transmitting end is connected to one end of the locking strip. The force-transmitting end works cooperatively with an elastic member, such that the locking strip and the locking portion are reciprocable in parallelism with a releasing direction.

Abstract: A molding technique for copper interconnecting wires by electrochemical displacement deposition on the pre-shaped metal layer in accordance with the present invention is used to form an adhering layer on a substrate and a sacrificial layer on the adhering layer. The sacrificial layer is patterned according to the copper interconnecting wires and displaced to form the copper interconnecting wires in a specific chemical solution.

Abstract: A solvent, such as deionized water, is heated up to boil to remove the oxygen dissolved in the water before preparing the plating solutions for the growth of copper interconnects. The resistance of the copper grown from the EDD solutions having undergone the oxygen-removing process is greatly improved, down to a value very close to copper's ideal value.
