Source sentences:
text: wherein the cells include outermost peripheral portion partial cells each locating in an outermost peripheral portion of the honeycomb structure and having an incomplete cell cross section, a part of which is brought into contact with the outer peripheral wall, and complete cells each having a complete cell cross section other than the outermost peripheral portion partial cells; wherein the complete cells have plugging portions in one end portions in such a manner that an end face of the honeycomb structure shows a checkerwise plugging pattern; outermost peripheral portion partial cells having a cell area ratio obtained by the following formula (1) of less than S 1 are formed unitarily with the outer peripheral wall so that the cells may be plugged over the entire length thereof; outermost peripheral portion partial cells having the cell area ratio of more than S 2 (S 1 <S 2 ) have plugging portions formed to have a depth smaller than that of the plugging portions of the complete cells; and outermost peripheral portion partial cells having the cell area ratio of S 1 or more and S 2 or less include cells formed unitarily with the outer peripheral wall so that the cells may be plugged over the entire length thereof and cells having plugging portions formed to have a depth smaller than that of the plugging portions of the complete cells (second honeycomb structure).
text: However, when also productivity is taken into consideration, it is favorable that the outermost peripheral portion partial cells having small cell area ratios and difficulty in forming plugging portions are formed unitarily with the outer peripheral wall so as to be plugged over the entire length.
text: The outermost peripheral portion partial cells 5 having difficulty in forming plugging portions because of relatively low cell area ratio are formed unitarily with the outer peripheral wall 4 to try to improve productivity.
text: , the cells where plugging is somewhat easy may be unitarily formed with the outer peripheral wall, which may reduce a breakage inhibition effect upon canning.
text: On the other hand, when the cell area ratio S 2 is more than 30 (%), the cells where plugging is somewhat easy may be unitarily formed with the outer peripheral wall, which may reduce a breakage inhibition effect upon canning.
text: There was manufactured a honeycomb structure where, in an end portion of each the complete cells of a honeycomb structure main body which is the same as the one used as in Example 1, a plugging portion having a depth of 3 mm or more in such a plugging pattern that the end faces of the honeycomb structure show a checkerwise pattern was formed; the outermost peripheral portion partial cells having a cell area ratio obtained from the aforementioned formula (1) of less than 5% of the honeycomb structure main body were formed unitarily with the outer peripheral wall so as to be plugged over the entire length; in the outermost peripheral portion partial cells having a cell are ratio of more than 30%, a plugging portion having a depth of less than 3 mm was formed in an end portion according to the aforementioned plugging pattern; and the outermost peripheral portion partial cells having a cell area ratio of 5% or more and 30% or less included both the cells formed unitarily with the outer peripheral wall so as to be plugged over the entire length and the cells each having a plugging portion a depth of less than 3 mm formed in an end portion according to the aforementioned plugging pattern.
