Patent number: 7393376Abstract: A ceramic filter assembly that resists cracking. The ceramic filter assembly is formed by integrating a plurality of columnar honeycomb filters made of a porous ceramic sintered material with a ceramic sealing material layer and formed to have a substantially elliptical cross sectional shape. The honeycomb filters includes square columnar honeycomb filters in which the ratio between the lengths of their long sides and short sides is between 1.1 and 3.0. The honeycomb filters are arranged so that the long sides and the short sides are respectively parallel to the major axis and the minor axis of the assembly.Type: GrantFiled: March 17, 2003Date of Patent: July 1, 2008Assignee: Ibiden Co., Ltd.Inventors: Noriyuki Taoka, Yutaka Yoshida

Publication number: 20060011916Abstract: A substrate for epitaxial growth includes a silicon-containing substrate, a silicon-germanium film, and a network-shaped structure. The silicon-germanium film is formed lamellarly on the silicon-containing substrate. The network-shaped structure is disposed adjacent to an interface between the silicon-containing substrate and the silicon-germanium film, and is composed of a 90-degree-dislocation dislocation line elongating continuously. The 90-degree-dislocation dislocation line making the network-shaped structure elongates remarkably long without being broken to short lengths interruptedly so that the 90-degree dislocation is disposed cyclically in planes parallel to the interface. Accordingly, the 90-degree dislocation is present uniformly in planes parallel to the interface. Consequently, strains in the crystal lattice of the silicon-germanium film have been uniformly relaxed more securely.Type: ApplicationFiled: March 25, 2005Publication date: January 19, 2006Applicant: NATIONAL UNIVERSITY CORPORATION NAGOYA UNIVERSITYInventors: Akira Sakai, Noriyuki Taoka, Osamu Nakatsuka, Shigeaki Zaima, Yukio Yasuda

Publication number: 20050169818Abstract: It is provide a filter for an exhaust gas having a high thermal conductivity irrespective of a relatively high porosity or showing characteristics that the whole of the filter containing a high refractive index substance or pigment is easily warmed but hardly cooled while making low the thermal conductivity of the filter as a whole. This filter is provided with a catalyst coat layer formed by carrying a catalyst active component on a surface of a porous ceramic carrier, in which a porosity of the porous ceramic carrier is 40-80% and a substance or a pigment indicating a thermal conductivity as the filter of 3-60 W/mk or having a large refractive index at a thermal conductivity of 0.3-3 W/mk.Type: ApplicationFiled: March 25, 2003Publication date: August 4, 2005Applicant: IBIDEN CO., LTD.Inventors: Kazushige Ohno, Noriyuki Taoka

Publication number: 20050160710Abstract: A honeycomb filter for purifying exhaust gases that can almost completely burn and remove particulates accumulated on a wall portion by a regenerating process allowing residual ashes on the wall portion to easily move inside a through hole because the ashes are easily separated from the wall portion. In the honeycomb filter a columnar body made of porous ceramics, having parallel through holes in the length direction with a wall portion interposed therebetween, is designed so that part or all of the wall portion that separates the through holes from each other functions as a filter collecting particulates, wherein a length l of the longest side in a cross section perpendicular to the length direction of the through hole and a length L in the length direction of the columnar body satisfy: 60?L/l?500, and a surface roughness Ra (according to JIS B 0601) of the through hole inner wall satisfies: Ra?100 ?m.Type: ApplicationFiled: March 4, 2003Publication date: July 28, 2005Inventors: Noriyuki Taoka, Yukio Oshimi

Publication number: 20040161596Abstract: There are proposed a diesel particulate filter being small in the pressure loss in the deposition of soot and high in the filtering efficiency and a ceramic sintered body constituting a main body thereof and a method of producing the same. The porous ceramic sintered body constituting the diesel particulate filter has communicated pores consisting of large pores 21 and small pores 22. The large pores are existent on at least surface layer portion of the sintered body, and the small pores 22 have a size relatively smaller than that of the large pore 21 and are existent on the surface layer and inside of the sintered body. Also, NOx occlusion catalyst is carried on the surface of the ceramic sintered body and the inner surfaces of the communicated pores.Type: ApplicationFiled: November 24, 2003Publication date: August 19, 2004Inventors: Noriyuki Taoka, Kazushige Ohno, Teruo Komori, Shinya Hirota, Yoshitsugu Ogura, Toshiaki Tanaka, Kazuhiro Itoh
