  • Publication number: 20240342654
    Abstract: A wall-flow type particulate filter includes: a wall-flow type base material; and a coat layer formed on the base material. The base material includes: an inlet cell open only at an exhaust gas inlet end; an outlet cell open only at an exhaust gas outlet end; and a partition partitioning the inlet and outlet cells and having multiple pores through which the inlet and outlet cells communicate with each other. The coat layer is provided for the wall surfaces of the pores and contains a first inorganic oxide and a second inorganic oxide. The mean particle diameter Da of the first inorganic oxide is larger than the mean particle diameter Db of the second inorganic oxide. The weight ratio of the second inorganic oxide is designed to be from 10% to 50% inclusive when the total weight ratio of the first inorganic oxide and the second inorganic oxide is 100%.

  • Patent number: 12090712
    Abstract: A method of manufacturing a composite includes bringing a first surface of a first base in which a first fiber base that is to constitute the first base is impregnated with a first resin into contact with a second surface of a second base in which a second fiber base that is to constitute the second base is not impregnated with a second resin, and impregnating the second fiber base with a portion of the first resin with which the first fiber base is impregnated.

  • Patent number: 12036510
    Abstract: An exhaust gas purification device suppresses a pressure loss increase and includes a honeycomb substrate and inflow cell side catalyst layer. The substrate includes a porous partition wall defining several cells extending from an inflow side end surface to an outflow side end surface. The cells include an inflow and outflow cell adjacent across the wall. The inflow cell has an open inflow side end and sealed outflow side end. The outflow cell has a sealed inflow side end and open outflow side end. The catalyst layer is on an inflow cell side surface in an region extending from the inflow side end positioned 10% or more of the partition wall length. At this position, a filled portion of the inflow cell side catalyst layer pores are 40% or less. The pores are present to a depth of 50% of a thickness of the partition wall.

  • Patent number: 7900177
    Abstract: A method of placing a dummy pattern in a wiring region includes calculating a density of a wiring pattern in the wiring region and calculating a value of a length of a periphery of the wiring pattern. The dummy pattern is then set such that a total of the pattern density and the value of the length of the periphery of the wiring pattern and the dummy pattern in the wiring region falls within specified ranges in the wiring region.

  • Publication number: 20100131915
    Abstract: Provided is a method of predicting a manufacturing defect part of a semiconductor device, which results from optical pattern displacement in an exposure process. The prediction method includes: performing repetitive processing a plurality of times, the repetitive processing including: a site generating step of setting a site at a predetermined position of a layout pattern; an edge shifting step of shifting an edge of the layout pattern according to a predetermined rule; an image forming position calculating step of calculating an image forming position corresponding to the shifted edge on the site; and an error check step of storing error information between the image forming position on the site and the edge of the layout pattern; and extracting, based on the error information, from the first layout data, apart in which the image forming position is unstable, and predicting the extracted part as a hot spot.
