The plurality of parts are formed of different honeycomb structures, respectively, so as to provide different heat insulation characteristics. The plurality of parts may be formed by different materials, or a shape or dimension such as a cell pitch of the honeycomb structure may be varied. Heat is collected from air within the honeycomb cells, and is transferred to other parts for heating.Type: GrantFiled: April 26, 2004Date of Patent: September 27, 2005Assignee: Tokyo Electron LimitedInventors: Osamu Suenaga, Wataru Okase, Takenobu Matsuo

Patent number: 6855393Abstract: A fire barrier panel of the kind suitable for lining car decks and engine rooms of high speed aluminum ferries is described. The panel (10) includes a relatively thin layer of inorganic insulating material (12) adhered to a lightweight support structure (14). The layer of inorganic insulating material may be an intumescent material made from mineral fibers. The decribed lightweight support structure (14) is a honeycomb panel having a honeycomb core (18) of non-combustible aluminum foil provided with two face skins made of glass reinforced plastics resin material (16). This construction of the honeycomb panel (14) is lightweight and has high stiffness and rigidity suitable for stiffening and supporting the insulating material into a rigid panel. The layer of intumescent material (12) supported on the panel expands when exposed to high temperatures to form a thick fire insulating barrier panel.Type: GrantFiled: June 16, 2000Date of Patent: February 15, 2005Assignee: Ashmere Holdings Pty Ltd.Inventor: Colin James Ayres

Publication number: 20040253407Abstract: A sandwich panel includes a honeycomb core of a plurality of cells. A first skin is adhered to a first surface of the honeycomb core with an adhesive. A second skin is adhered to a second surface of the honeycomb core with the adhesive. The plurality of cells extend longitudinally between the first and second skins. The first and second skins adhere to the honeycomb core to form a sandwich panel having a surface area of at least 2.25 square feet. A foam fill is disposed within the cells of the honeycomb core. The foam fill and the honeycomb core define a first gap region proximate to the first skin and a second gap region proximate to the second skin.Type: ApplicationFiled: June 12, 2003Publication date: December 16, 2004Applicant: Northrop Grumman Corporation;Inventors: Chandrakant Himatlal Shah, Tod Palm, Timothy Alan Dyer, Carl A.

Patent number: 6828001Abstract: The present invention is directed to cost-effectively provide a high-strength large vacuum heat-insulating panel with a honeycomb core of non-permeable independent cells by means of simplified instruments and method. One goal of the invention is that the core retains an original shape at its lateral ends from the beginning of a procedure of evacuating air into a vacuum condition till the end of panel bonding, and another is ensuring a long lasting air-tight sealing in the honeycomb core. The vacuum heat-insulating panel 100 according to the invention includes a vacuum core element (50) of non-permeable honeycomb structure and a surface element (60) bonded thereto by fusing an air-permeable bonding element (woven cloth made of fibrous adhesive of thermoplastic resin or unwoven cloth of the fibrous adhesive) 70. The surface element 60 has its edges bent to provide protection covers 65.Type: GrantFiled: April 19, 2002Date of Patent: December 7, 2004Assignee: Jamco CorporationInventors: Hideo Tokonabe, Katsuhiko Umeda

Patent number: 6824851Abstract: A mass transit flooring assembly including a plurality of sandwich panels. The sandwich panels (30) include a top skin (54), a bottom skin (58), a perimeter defining closeout (46), and a core (50) between the top (54) and bottom skin (58) and within the closeout parameter (46). The closeout (46) includes mating surfaces used to connect adjacent panels. The core is a precured reinforced core including a plurality of phenolic ribs and foam strips positioned in an alternating fashion. The precured core is manufactured by impregnating a layer of fabric with phenolic resin between two foam cores and stacking in a similar alternating fashion to create a bun. After the bun is cured at a constant pressure and temperature and cooled, the bun is cut along a plane perpendicular to the plane of the layers to provide a precured reinforced core panel ready to be inserted as a core in a sandwich panel.Type: GrantFiled: April 5, 2002Date of Patent: November 30, 2004Assignee: Milwaukee Composites, Inc.Inventors: David M.
