A load bearing panel member having a first portion, a second portion, and an appearance surface portion is formed by injection molding such that the first portion includes a plurality of ribs forming a grid pattern on the first portion and another plurality of ribs extending toward the periphery of the first portion which may be non-orthogonal to each other and to the ribs forming the grid pattern. An internal channel may be formed within each of the non-orthogonal ribs by injecting a gas into the rib during the molding process forming the panel. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member. The panel member may be configured as a floor panel of a vehicle.

A penetration structure for a fireproof compartment has a through hole(s) provided at a compartment and a pipe(s) penetrating through the through hole(s). A circumference of the pipe(s) is wound by an epoxy resin-containing thermally expandable resin composition sheet. The epoxy resin-containing thermally expandable resin composition sheet is a laminate of one or more epoxy resin-containing thermally expandable resin composition layers having at least one of linear grooves continuously formed and linear grooves intermittently formed, and two or more of the respective linear grooves being formed onto at least one surface of the epoxy resin-containing thermally expandable resin composition sheet with an interval, and one or more substrate layers. The epoxy-resin-containing thermally expandable resin composition sheet can be wound around the pipe by bending the sheet through use of the grooves even when the temperature is low.

The present invention relates to a thermoplastic film having improved tear and puncture resistance. The thermoplastic film has a plurality of embossed regions that are comprised of a plurality of parallel, linear embosses. The plurality of embossed regions is arranged so that a straight line cannot traverse the thermoplastic film without intersecting at least one of the plurality of embossed regions. Certain embodiments further disclose an unembossed arrangement having at least three distinct segments that extend in three distinct directions.

This grain-oriented electrical steel sheet is a grain-oriented electrical steel sheet including a base steel sheet and a tension coating, in which, when an average coating thickness of a flat surface coating portion is referred to as t1 (m), a minimum coating thickness of a groove forming surface coating portion is referred to as t2.sub.Min (m), and a maximum coating thickness of the groove forming surface coating portion is referred to as t2.sub.Max (m), Expressions (1) and (2) are satisfied, and when a value of 0.95 times a distance D of the tension coating along a sheet thickness direction from a bottom surface position of the groove forming surface coating portion to a bottom surface position of the flat surface coating portion is referred to as an effective depth d (m), Expression (3) is satisfied.

A snow sock is provided that includes a covering that extends in a circumferential direction. The covering has a thickness and an outer surface. A first thickness section is present and extends along a first arc length, and has a first thickness section inner surface that engages the outer surface of the covering. At least 50% of the first thickness section inner surface engages the outer surface of the covering and/or a first fill element. A second thickness section is also provided and is spaced from the first thickness section. The second thickness section extends in the circumferential direction along a second arc length, and has a second thickness section inner surface that engages the outer surface of the covering. At least 50% of the second thickness section inner surface engages the outer surface of the covering and/or a second fill element.
