摘要:
A manufacturing method of a plugged honeycomb structure including attaching a transparent sheet to an end face of a honeycomb structure; picking up an image of the end face; with respect to cells positioned at other than outermost peripheral portion of a honeycomb structure (usual cells), subjecting the picked-up image to image processing, recognizing positions to be plugged on said sheet, and with respect to cells positioned at outermost peripheral portion (outermost peripheral cells), positions of the cells are recognized based on an average cell pitch calculated from the positions of the cells, subjecting to a perforation treatment based on the recognized positions of the sheet, submerging an end portion into a plugging slurry in which a material of the plugging portions is slurried, filling holes made at the respective sheet with the slurry to form the plugging portions.

There is provided a honeycomb structure including: porous partition walls separating and forming a plurality of cells extending between two end faces, and an outer peripheral wall formed unitarily with the partition walls. 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. The complete cells and the outermost peripheral portion partial cells having plugging portions formed on one end portion so that an entire end face of the honeycomb structure shows a checkerwise plugging pattern, and the depth of the plugging portions in the outermost peripheral partial cells is smaller than that of the plugging portions in the complete cells.

A method of manufacturing a plugged honeycomb structure has a plugging process which includes the steps of: immersing one end (a first end) of a honeycomb base material in a plugging slurry while vibrating the plugging slurry; after bringing an internal part of a cell into a negative pressure and then returning it into an atmospheric pressure, vibrating the plugging slurry to make the plugging slurry enter a first open end of the cell; and drying the plugging slurry having entered the first open end of the cell to form a first plugging portion at the first end.

A method is provided for manufacturing a plugged honeycomb structure 30 including a honeycomb substrate 1 and plugging portions 15 arranged so as to form complementary checkered patterns at both end surfaces 11 and 21 of the honeycomb substrate 1. The method includes attaching a first mask film 4a to the first end surface 11 of the honeycomb substrate 1, making slurry permeation holes 3a to introduce a plugging slurry 6, attaching a second mask film 4b to the second end surface 21 of the honeycomb substrate 1, making slurry permeation holes 3b, allowing air to flow into the cells 2 so as to discharge air giving a pressure of 0.05 to 5 MPa between the first mask film 4a and the honeycomb substrate 1; and filling cell opening end portions 7 with the plugging slurry 6 to fire the resultant slurry filled substrate 20.
摘要:
A honeycomb structure comprising porous partition walls which form, by surrounding, a plurality of cells extending between the two ends faces of the honeycomb structure, and an outer wall formed integrally with the partition walls. The cells consist of partial cells of outermost peripheral portion, having incomplete cell sections, which are located at the outermost peripheral portion of the honeycomb structure and are in partial contact with the outer wall, and complete cells having a complete cell section, other than the partial cells of outermost peripheral portion. In the complete cells, a plugged part is formed at one end of each complete cell so that each end face of the honeycomb structure shows a checkerwise plugging pattern. In the partial cells of outermost peripheral portion to be plugged according to the above-mentioned plugging pattern, part of them is plugged in the entire length and formed integrally with the outer wall and remaining cells have each a plugged part only at one end.

A manufacturing method of a plugged honeycomb structure 30 which comprises a honeycomb substrate 1 and plugging portions 15 arranged so as to form complementary checkered patterns alternately at both end surfaces 11 and 21 of the honeycomb substrate 1. The method comprises attaching mask films 4a and 4b to both end surfaces 11 and 21 of the honeycomb substrate 1, respectively; forming slurry permeation holes 3a at portions of the mask films 4a and 4b corresponding to cell opening end portions 7, respectively; forming deaeration holes 3b at portions of the mask films 4a and 4b facing the portions provided with the slurry permeation holes 3a via cells 2; submerging both end surfaces 11 and 21 of the honeycomb substrate 1 to which the mask films 4a and 4b have been attached into a plugging slurry 6, respectively; and firing the resultant slurry filled substrate 20.

In a mobile terminal provided with an encoded data recording function, there is assumed a condition in which a picture frame transmitted from the terminal of a communication partner is reproduced by means of decoding processing and is displayed on a LCD (34) during wireless TV phone communication. In this condition, when a user carries out a picture recording start operation, display picture data reproduced by means of decoding processing in the multimedia processing section (24) to be displayed on the LCD (34) are recorded in a main recording section (26).
摘要:
A main body controller provided in an image forming apparatus receives a VDP job from an external computer, and arranges image data of a reusable object and a variable object, which correspond to the VDP job, on a page for printout. An inspection controller performs inspection processing for printed matter for each page, and the main body controller preferentially stores image data of the reusable object, which corresponds to the page for which the printing has been determined to be defective as a result of inspection processing, in a cache unit. The main body controller acquires the reusable object, which corresponds to the page for which the printing has been determined to be defective, from the cache unit, and executes page reprint processing using the acquired reusable object.
