摘要:
An exhaust gas purifying device for an internal combustion engine includes an inflow case provided with an inlet pipe, a catalyst case in which an oxidizing catalyst for dosing is housed, a filter case in which a soot filter is housed, and an outflow case provided with an outlet pipe, and is attached to an attached target at two attachment points mutually spaced in the axial direction of the cases. At one of the two attachment points, which is defined on the catalyst case, the catalyst case is firmly fixed. At the other attachment point, which is defined on the filter case, the filter case is attached slidably in the axial direction.

Disclosed is a compound represented by Formula (I) or a pharmaceutically acceptable salt thereof: wherein R1 is 1: a C3-8 cycloalkyl C1-4 alkyl group, 2: a C7-14 aralkyl group, in which the aryl moiety thereof is optionally substituted with the same or different 1 to 3 groups selected from the group consisting of: (a) halogen, (b) C1-4 alkyl, which is optionally substituted with 1 to 3 fluorine atoms, (c) C1-4 alkoxy, which is optionally substituted with 1 to 3 fluorine atoms, and (d) C1-4 alkylcarbonyl, which is optionally substituted with C1-4 alkoxy, 3: a five-to ten-membered heteroaryl-C1-4 alkyl group, in which the heteroaryl moiety thereof is optionally substituted with the same or different 1 to 3 groups selected from the group consisting of: (a) halogen, and (b) C1-4 alkyl, or 4: a C6-10 aryl C2-6 alkenyl group; and R2 is a cyano group or a nitro group.

An exhaust gas emission control system includes a cylindrical main body shell and an outlet shell that are detachably connected in series along an exhaust gas flow direction. The exhaust gas emission control system also includes a CSF provided in the main body shell, an insulating mat interposed between the main body shell and the CSF, a bulging portion provided at an end of the main body shell near the outlet shell, and a flare that enlarges toward the main body shell. The main body shell and the outlet shell are mutually connected by a fastener having a V-insert that bridges the bulging portion and the flare. An end of the CSF near the outlet shell projects beyond an end of the insulating mat toward the outlet shell while being positioned inside the end of the main body shell.

A distance from the bottom of a mesa groove to an underlying pn junction exceeds the elongation of a depletion layer from the underlying pn junction that occurs when a voltage nearly equal to a target withstand voltage is applied, and a groove width of a section other than a corner of the mesa groove, that is, the groove width of a straight section, is nearly equal to the distance from the bottom of the mesa groove to the underlying pn junction.
