摘要:
A panel includes a base layer configured to have plural first protuberances; a core layer disposed on the base layer and configured to have plural second protuberances, wherein one or more of the plural second protuberances have first slots in a top portion; inserts provided on the base layer and inside the one or more of the plural second protuberances of the core layer; and a top layer in direct contact with the plural first protuberances and the plural second protuberances and configured to have second slots that correspond to the first slots. The inserts are exposed to ambient through the first slots and the second slots.

A plastic sheet having a number of recessed and protruded parts useful as a protective sheet in moving and construction, and for cushion packaging and thermal insulation is disclosed. Also disclosed is a two-layered or three-layered double wall sheet, which is produced by adhering one or two flat plastic sheets on the above plastic sheet. The double wall sheet has high rigidity against bending and improved warps when compared with the conventional plastic bubble boards, and is useful as the material for various panels and packaging containers. The plastic sheet is produced by vacuum forming to form plural protruded, truncated cone-shaped parts and recessed, ring-shaped parts surrounding and continuing from the protruding parts. The double wall sheet is produced by adhering a back sheet and/or liner sheet to the plastic sheet.

Introduction guides 12 are provided above and below a sheet-introduction opening portion of a pressure-reduced chamber 10, and heating means 17 is provided between the introduction guides. Each resin sheet 3 is attracted and attached respectively to the circumferential surface of a corresponding emboss roller 11 by reducing pressure. Pins 112 of the emboss roller 11 are truncated cone-shaped. The ratio of the total area of the lower bases of the pins 112 to the area of the circumferential surface of the emboss roller is 0.5 or more. The rising angle θ of the pin side face, in the vertical plane including the central axis of the pins 112, is in the range from 50 degrees to 70 degrees. Furthermore, a multilayered hollow structure plate 140 is formed by attaching non-air-permeable sheets 130 onto both the front and back of a core member obtained by fusing together hollow protrusions 112 in two thermoplastic resin sheets. A sound absorbing material 150 is provided on at least one of the front and back side thereof, and small holes 114a opened in the multilayered hollow structure plate are formed in liner portions 114 and the non-air permeable sheet 130 only in the positions that matches the liner portions 114.
摘要:
A dynamic structural panel having one or more compliant dimple layers connected together by one or more reinforcing layers engaging ends of dimples on the dimple layer to create a cavity between the layers. The dimples are spaced apart from one another to form a dimple layer region. The dimple layer region may be either curved relative to the dimples or corrugated, thereby providing compliancy for the dynamic structural panel. The connection of the dimple layer and reinforcing layers creates an integral structural panel that can be planar by having identical heights of the dimples on the dimple layer to create a planar panel (flat) or nonplanar (curved) by varying the heights of the dimples on the dimple layer or through planar spacing adjustment. The panel can be modified in various ways such as by choice of materials and/or geometries of the various layers and/or incorporation of additional structural features.

Sound-absorbing unit is provided with a high sound-absorbing/insulating capability. The sound-absorbing unit (60) includes a corrugated partition plate (52) whose antinode portions (52a, 52b) extend in a first direction (Y); a sound-absorbing material (51) provided on the corrugated partition plate (52); and a second partition plate (53) which extends in a second direction (X) and which partitions air portions (70) defined between the corrugated partition plate (52) and the sound-absorbing material (51).

A room-bounding structure (e.g., walls, floor and/or ceilings), in accord with an embodiment of the invention, includes a rigid sheet impermeable to moisture; spacer protrusions on the first surface of the sheet at essentially even intervals over the entire area of the sheet; and a rigid surface sheet supported on the spacer protrusions, in such a way that the space between the sheet and the surface sheet forms a network of air channels for ventilating the structure. In another embodiment of the invention, a structural system for a room-bounding structure includes a casted structure, and a perforated conduit with an inlet and outlet outside the casted structure, at least a portion of the conduit embedded in the casted structure. Such room-bounding structures may be utilized as part of a modular room that includes one or more utility connections for connecting a utility system to the modular room.

A lightweight composite article is described. The lightweight composite article comprises: (a) two substantially opposed plates, at least one of the plates is a metal plate; and (b) a support structure of thermoplastic material interposed between the plates, the support structure defining a plurality of hollow spaces. Each of the plates (a) is fixedly attached to the support structure (b) by means of a plurality of anchors, which are distributed substantially uniformly over the surface of each of the plates. The support structure may be in the form of a ribbed support structure and/or an egg-box shaped support structure. Also described are articles of manufacture which comprise the lightweight composite article of the present invention, e.g., automotive components.
