Title
(EN) HONEYCOMB STRUCTURE AND EXHAUST GAS PURIFICATION DEVICE
(FR) STRUCTURE EN NID D'ABEILLES ET DISPOSITIF DE PURIFICATION DE GAZ D'ÉCHAPPEMENT
(JA) ハニカム構造体及び排気ガス浄化装置
Abstract
(EN)
This honeycomb structure in a columnar shape has outer peripheral walls, and porous partition walls arranged inside the outer peripheral walls and forming a partitioned plurality of cells that form flow paths running through from one end surface to the other end surface. The cells include two or more types of magnetic bodies which differ in at least two characteristics among maximum magnetic permeability, Curie point, and resistivity.
(FR)
La présente invention concerne une structure en nid d'abeilles en forme de colonne qui comporte des parois périphériques externes, et des parois de séparation poreuses disposées à l'intérieur des parois périphériques externes et formant une pluralité de cellules séparées qui forment des trajets d'écoulement s'étendant à partir d'une surface d'extrémité vers l'autre surface d'extrémité. Les cellules comprennent au moins deux types de corps magnétiques qui diffèrent en au moins deux caractéristiques parmi la perméabilité magnétique maximale, le point de Curie et la résistivité.
