Patent number: 11970961Abstract: A pillar shaped honeycomb structure, including: a porous partition wall that define a plurality of cells, the plurality of cells forming flow paths for a fluid, the plurality of cells extending from an inflow end face to an outflow end face; and an outer peripheral wall located at the outermost circumference. The plurality of cells include: a plurality of first cells; and a plurality of second cells having a lower cross-sectional area than that of the plurality of first cells. An interior of each of the second cells is filled with a material comprising a magnetic substance. Each of the second cells are arranged adjacent to at least one of the first cells.Type: GrantFiled: May 19, 2021Date of Patent: April 30, 2024Assignee: NGK INSULATORS, LTD.Inventors: Yukio Miyairi, Masaaki Masuda, Kyohei Kato, Norihiro Wakida
