Publication number: 20080161482Abstract: The present invention discloses a functional material powder, a method for fabricating the same and a functional staple fiber containing the same. The functional material powder comprises particles with a diameter of 50˜350nm, 0.5˜1.5% of a dispersant, 3˜5% of a surfactant, and 1˜2% of a coupling agent. A small-capacity mill is used to fabricate the functional material powder of the present invention, wherein the small-capacity mill operates at a high power to generate a great impact force and a great shear force to fast nanomize the particles of the functional material. Further, in considering the future application, a surfactant and a coupling agent are added into the functional material powder to disperse the powder and promote the coupling strength between the particles and the molecules of a chemical fiber.Type: ApplicationFiled: December 29, 2006Publication date: July 3, 2008Inventor: Chih-Lien Ko

Publication number: 20080142966Abstract: There is provided a composition that is suitably used for a flip chip mounting process or a bump-forming process. The composition comprises a first component 3a, a second component 3b, metal particles 1,1? and a convection additive. The metal particles 1,1? are dispersed in the second component 3b. The convection additive is contained in the second component 3b. The first component 3a is contained in an interior of at least one particle 1. When such at least one metal particle 1 melts upon heating, the first component 3a comes in contact with the second component 3b to form a thermoset resin 3c. The convection additive is capable of generating a gas upon heating, so that the gas provides a convection effect in the composition.Type: ApplicationFiled: March 6, 2006Publication date: June 19, 2008Inventors: Koichi Hirano, Seiji Karashima, Takashi Ichiryu, Yoshihiro Tomita

Patent number: 7388050Abstract: A hyperbranch polymer is bonded to a pore surface existing on a SiO2 glass porous body, such that the hyperbranch polymer is bonded to the pore surface only at the base end moiety. The hyperbranch polymer has a first generation branched moiety branched from the base end moiety, a second generation branched moiety further branched from the first generation branched moiety, and a third generation branched moiety further branched from the second generation branched moiety. A functional group, such as sulfonic acid group, from which a proton is capable of being dissociated, is bonded by substitution to the terminal end of the third generation branched moiety.Type: GrantFiled: December 23, 2004Date of Patent: June 17, 2008Assignee: Honda Motor Co., Ltd.Inventors: Hitoshi Iwadate, Yuji Isogai
