Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A device for machining a work piece creates an electrical potential between an electrode and the work piece or another conducting body proximate to the work piece. The electrical potential establishes an electrical field within the work piece that is expected to repel electrons and create a region of positively charged ions which repel one another. This region is expected to be weakened and material is expected to be removable from this region of the work piece using less force and energy than when machined by traditional machining techniques.

Provided are a three-dimensional shaped object production device and method capable of producing a predetermined three-dimensional shaped object by forming a ball at a leading end of a conductive wire through use of the conductive wire based on scanned data or designed data and aligning and stacking the balls. The three-dimensional shaped object production device includes: a plate (40), on which a three-dimensional shaped object is placeable; a ball forming section configured to form a ball (13) by applying high voltage between a leading end of a conductive wire (4) paid out from a leading end of a capillary (12) and a spark rod (19) and melting the leading end of the wire by discharge energy; a positioning device configured to position the plate and the ball forming section by moving the plate and the ball forming section relative to each other; and a bonding section configured to bond the ball formed at the leading end of the capillary to another ball (14) that has already been stacked on the plate, the forming of the ball by the ball forming section, the relative moving of the plate and the ball forming section by the positioning device, and the bonding of the ball formed at the leading end of the capillary to the another ball by the bonding section is repeated, to thereby produce a three-dimensional shaped object having a desired shape.

A magnetizable cylinder has a cylinder body formed from a magnetizable material with an outer cylindrical surface configured to receive a flexible cutting die. The cylinder body has first and second axial ends spaced apart by the outer cylindrical surface and a hollow interior. First and second journals are joined to the cylinder body with interference fits. At least one of the first and second journals has a weep hole extending through the journal into the hollow interior of the cylinder body. The interference fit of the journals to the cylinder body result from thermal changes of at least one of the first journal, the second journal, and the cylinder body prior to joining the first journal to the cylinder body and the second journal the cylinder body.

A three-dimensional (3D) printer is configured to introduce a liquid metal onto a first part and a second part while the first part and the second part are in contact with one another. The liquid metal subsequently solidifies to join the first part and the second part together to produce an assembly.

The present invention includes systems, assemblies, and methodologies for inhibiting combustion within fluid containers, enhancing the safety of such containers. One aspect includes a novel base module from which assemblies of varying shape and size, suitable for disposing within a variety of different fluid containers, are created. In one embodiment, the base module is made from an expanded mesh which is rolled in a novel cylindrical configuration according to a novel methodology. In another embodiment, the base module may be combined with other base modules to form an assembly. The present invention is also directed to an apparatus and method for creating base modules which allows for varying density of the base modules and therefore varying flexural strength and rigidity of the assemblies. As such, the packing density of assemblies within containers may be optimized to produce the desired effect of inhibiting combustion within the container.
