Abstract: Process to decrease silicon content of metal powder produced by hydrogen reduction from ammoniacal ammonium sulphate solutions containing metal ammine complexes, wherein metal (Me) is Ni, Co, or Cu. The process controls the precipitation of metal hydroxide, which is found to be an effective scavenger for silicon. Silicon is preferentially removed from metal diammine sulphate-containing solutions by precipitating with a small amount of a metal hydroxide, and then separating the silicon-bearing metal hydroxide precipitate from the solution. This solution, from which the silicon impurity has been removed with the metal hydroxide precipitate, can then be reduced in one or more densification cycles with a reducing gas to produce an elemental metal powder having a decreased silicon content. Alternatively, the solution is reduced to produce a low silicon metal powder seed material for the first of the one or more densification cycles.

Abstract: A storage device assembling module for assembling a storage device in an electronic apparatus includes a main frame, an adapter, and at least one handgrip. The main frame includes a chute forming a receiving space for receiving the storage device and positioning. The adapter is combined with the main frame and includes a first connecting port connected electrically to the storage device and a second connecting port connected electrically to a circuit board. The location of the first connecting port is closed to the chute, and the connecting direction of the first connecting port is substantially perpendicular to the connecting direction of the second connecting port. Each handgrip is connected pivotally to at least one side of the main frame which is away from the circuit board. The storage device assembling module can substantially be perpendicularly detached from the circuit board by pulling the at least one handgrip.

Abstract: A measuring tool includes a tool body and a first measuring unit. The first measuring unit includes a first probe, a first measuring meter, and a first zero button. The first probe is used for contacting a standard part or a test part inside the tool body. The first measuring meter is connected to the first probe for displaying a first zero value or a first measure value. The first zero button is used for zeroing the first measuring meter to display the first zero value when the first probe contacts the standard part. When the first probe contacts the test part after the first measuring meter is zeroed, the first measuring meter displays the first measure value. A first dimension difference value of the test part and the standard part is equal to a difference value of the first measure value and the first zero value.

Abstract: A hard disk device frame for fastening a plurality of hard disk devices, a fan, and a main board is disclosed. The hard disk device frame includes a rotary piece, a back chassis, and plural hinges. The rotary piece includes a front chassis having an opening; and a bracket fixed on the front chassis, wherein the hard disk devices enter the opening and couple to the bracket. The fan and the main board are fixed on the back chassis. The hinges connect the front chassis and the back chassis, thereby the rotary piece is pivoted relative to the back chassis to hide or expose the fan and the main board on the back chassis.

Abstract: An HDD frame is used to fix several HDDs and several HDD cables. The HDD frame includes an HDD cage, a latch and an HDD cable bracket. The HDD cage includes three cage boards. Two of the cage boards are disposed at two ends of the other cage board. The latch includes a protrusion. The HDD cable bracket includes a baseboard and a sideboard, which are perpendicular to each other. The baseboard includes a first long edge and a second long edge. The sideboard is disposed at the second long edge. One end of the latch is fixed on the end of the sideboard to make the protrusion protrude through the sideboard hole of the sideboard. After the long edges of the HDD cable bracket are inserted into tracks on the HDD cage, the protrusion protrudes into the cage hole of the HDD cage.
