A casing for a portable electronic device, comprising at least a first and a second cover member and a frame unit. The first and second cover member may be attached to the frame unit and the second cover member may enclose a part of the frame unit, wherein the casing enclose the portable electronic device and is self supporting when the first and second cover member and the frame unit are assembled.

A B-shaped reinforcement beam is formed from a sheet of material to include vertically spaced upper and lower tubular sections, with a channel-shaped rib formed centrally in the unsupported portion of the front wall over each tube section. The ribs acts to stiffen and stabilize the front wall, causing the actual bending strength of the B beam to be much closer to expected theoretical values. In one form, the ribs have a vertical dimension about 33%-50% of a height of the tubular sections and a depth of about 50%-100% of the rib's height. The rib is particularly effective when the material is less than 2.2 mm, more than 80 KSI, and / or has a significant height-to-depth ratio such as 3:1.

A gutter guard for mounting on a gutter. The gutter guard comprises an elongated panel extending laterally from an inner portion to an outer portion of an underlying gutter. The panel is of undulating construction and comprises a plurality of longitudinally extending, laterally spaced, elongated raised areas for retarding the flow of rain water across the panel. The raised areas are separated by longitudinally extending recess channels. The raised areas and recessed channels have a plurality of longitudinally extending, laterally spaced rows of longitudinally spaced first holes extending through the panel to enable rain water flowing outwardly across the panel to flow through the first holes into an underlying gutter. The first holes have a narrow end portion facing the inner side of the panel and expanding outwardly toward the outer side of the panel to facilitate spreading of rain water as it travels across the panel toward the outer side thereof.

The present invention provides a crosslinked polyolefin-based resin-extruded foam sheet capable of reducing its thickness while retaining excellent flexibility and heat resistance. The crosslinked polyolefin-based resin foam sheet of the present invention is obtained by feeding a polyolefin-based resin and a thermally degradable blowing agent to an extruder, melting and kneading them, extruding the kneaded material through the extruder into a sheet to form an expandable polyolefin-based resin sheet, and expanding the sheet. Herein, a degree of crosslinking of the crosslinked polyolefin-based resin foam sheet is 5 to 60% by weight, an aspect ratio of a cell (MD average cell diameter / CD average cell diameter) is 0.25 to 1, and the polyolefin-based resin contains 40% by weight or more of a polyethylene-based resin obtained using a metallocene compound containing a tetravalent transition metal as a polymerization catalyst.

Sheets for use in a binding apparatus, the sheets being conditioned by removing the outer layer of the sheet on one or both surfaces along the sheet edge that will be bound.

Embodiments include structural metal stud framing members with an improved web design. The structural metal stud framing member with the improved web design are referred to as an amplified metal stud member. Embodiments include a bracing structure and a stiffening structure to collectively increase the axial and lateral load capacity of the stud. In other words, embodiments increase the internal strength to weight ratio for both the overall axial and lateral load.

Provided is a process of producing a solar battery module 1 including plural solar battery cells 4 sealed by a resin 5 between a transparent panel 2 of the light reception surface side and a back face panel 3, which is characterized by arranging plural solar battery cells 4 at a prescribed interval and mutually connecting them to each other by a conductor 8; arranging a first sealing resin sheet 12 substantially covering the entire surface of the transparent panel 2 of the light reception surface side between the transparent panel 2 of the light reception surface side and the solar battery cells 4; arranging a second sealing resin sheet 10 substantially covering the entire surface of the back face panel 3 between the back face panel 3 and the solar battery cells 4; arranging sealing resin sheet pieces 18, 19 which are thicker than the solar battery cells 4 at a space 9 between the solar battery cells 4 so as to be sandwiched by the first sealing resin sheet 12 and the second sealing resin sheet 10; discharging air between the transparent panel 2 of the light reception surface side and the back face panel 3; and heating the resin 5 for melting and then cooling down it for sealing. According to this, when the plural solar battery cells 4 are arranged and sealed by the resin 5, breakage of the solar battery cells 4 can be prevented from occurring.

A press forming die assembly for press forming a blank material includes a draw forming portion that the blank material flows and a draw bead for controlling the amount of the blank material flowing into the draw forming portion. A first draw bead is provided at a periphery of the draw forming portion in a direction substantially parallel to an outer peripheral shape of the draw forming portion. A second draw bead extends from the first draw bead toward the outside of the draw forming portion in a direction intersecting the first draw bead. The blank material includes a thick sheet portion having a greater thickness than the other portion or a high rigidity portion having a higher rigidity than that of the other portion. The second draw bead is provided at a portion corresponding to the thick sheet portion or the high rigidity portion of the blank material.

A hot-rolled high strength steel sheet in which, without using expensive Mo, and by effectively using Ti, which is an expensive element, the amount of precipitation hardening of which is large, both ductility and stretch-flangeability are improved at a tensile strength of 780 MPa or higher, and desirable tensile fatigue properties are exhibited. The hot-rolled high strength steel sheet has a composition including, in percent by mass, C: 0.06% to 0.15%, Si: 1.2% or less, Mn: 0.5% to 1.6%, P: 0.04% or less, S: 0.005% or less, Al: 0.05% or less, and Ti: 0.03% to 0.20%, the balance being Fe and incidental impurities, wherein the steel sheet has a structure in which the volume fraction of ferrite is 50% to 90%, the balance is substantially bainite, the total volume fraction of ferrite and bainite is 95% or more, precipitates containing Ti are precipitated in the ferrite, and the precipitates have an average diameter of 20 nm or less; and 80% or more of the Ti content in the steel is precipitated.

A sheet compression apparatus includes a pair of nipping members configured to be movable so as to contact and separate from each other and to compress a sheet while the sheet is nipped, and a contact / separation mechanism configured to perform a contact / separation operation of the pair of nipping members, and the contact / separation mechanism separates the nipping members from each other until a leading edge of the sheet fed by the sheet feeding unit passes between the nipping members, and then relatively moves the pair of nipping members closer to each other to start the nipping of the sheet so the sheet is compressed.
