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.

Publication number: 20040226653Abstract: A table receives an object, subjected to the adhesion process, in an adhesive setting apparatus. An adhesive have been applied on the object on the table. An exposure mechanism is designed to expose the adhesive to a gaseous accelerator. The adhesive setting apparatus utilizes the gaseous accelerator to promote the setting or hardening of the adhesive. The gaseous accelerator uniformly contacts the adhesive as compared with the mist of the accelerator. Since the adhesive is uniformly exposed to the gaseous accelerator, an uneven progression can reliably be avoided in the setting of the adhesive. It is possible to reliably avoid heterogeneity or localization of the set adhesive.Type: ApplicationFiled: June 22, 2004Publication date: November 18, 2004Applicant: FUJITSU LIMITEDInventors: Hirokazu Yamanishi, Tomokazu Sugiyama, Tsutomu Sooda, Yoshiaki Yanagida

Publication number: 20040216838Abstract: Method for the production of components for electronic apparatuses from a sheet-like substrate material, which has through-holes and indentations on at least one surface, an intermediate layer on at least one surface of the substrate material, and a metal foil adhering to said layer, comprising the steps (a) coating of a sheet-like substrate with a composition forming the intermediate layer, (b) application of the metal foil to the coating and (c) bonding of the parts by pressure and heating. The method is characterized by the use of a liquid, solvent-containing and heat-curable two-component system comprising at least one curing agent and at least one curable compound, which system is applied as the layer to at least one surface of a substrate material and then dried. A metal foil is then laminated with the resulting solid and dry layer under pressure and at elevated temperature and the layer is cured. Particularly preferably, circuit boards are produced by the method according to the invention.Type: ApplicationFiled: November 21, 2003Publication date: November 4, 2004Inventors: Anders V.

Publication number: 20040173302Abstract: A metal material adhesion method is described. The method is used for an optical transceiver module assembly process to adhere a protection cover of a laser diode in a metal shell and enhance the adhesion strength thereof. The method employs the following steps. First, the protection cover and the metal shell are provided. A primer layer is coated inside the metal shell. The laser diode is aligned with the metal shell to provide a maximum signal strength position. An epoxy layer is glued between the metal shell and the protection cover to fix the laser diode in the best position. The method further provides a sealant layer to protect the epoxy layer from moisture and a second premier layer to enhance the adhesion strength between the protection cover and the epoxy layer.Type: ApplicationFiled: June 23, 2003Publication date: September 9, 2004Applicant: Delta Electronics, Inc.Inventor: Wien-Haurn Kuu
