Patent number: 7131797Abstract: A tool holder has a cutter arbor. The cutter arbor has a shank portion detachably mounted on a spindle, and a mechanism for holding a cutting tool. In the cutter arbor portion, a cavity portion is formed. In the cavity portion, a vibration damping material is filled at a filling rate so as to be capable of obtaining predetermined vibration damping characteristics. Thus, it is possible to provide high vibration damping characteristics, effectively damp vibrations during cutting and improve working precision, without using any special materials, such as damping materials, although the tool holder has a usual shape.Type: GrantFiled: December 11, 2002Date of Patent: November 7, 2006Assignee: Toshiba Kikai Kabushiki KaishaInventors: Yoshiaki Kai, Katsuhito Endo, Yutaka Asanome, Kouichi Katoh

Patent number: 6829135Abstract: Resin thin films (12) and metal thin films (11a, 11b) are layered in alternation. The metal thin films are set back from the peripheral edges of the resin thin films (12). Via holes (13a, 13b) penetrating the layered product in the layering direction are formed and filled with conductive material (14a, 14b). The conductive material (14a, 14b) electrically connects the metal thin films (11a, 11b) among one another. The metal thin films are not exposed at the periphery, so that corrosion of the metal thin films is not likely to occur. Furthermore, cutting of the metal thin films during the manufacturing process is avoided.Type: GrantFiled: November 27, 2001Date of Patent: December 7, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuyoshi Honda, Noriyasu Echigo, Yoshiaki Kai, Masaru Odagiri, Nobuki Sunagare
