Abstract: In a method of producing a honeycomb structured body, a die for extrusion molding is provided to produce at least one honeycomb molded body. The die includes a die body having a raw material inlet side face and a molded body extrusion side face. The raw material inlet side face includes raw material supply holes for supplying a ceramic raw material. The molded body extrusion side face includes molding grooves for molding the ceramic raw material into a shape of the at least one honeycomb molded body. The raw material supply holes and the molding grooves communicate with one another through connecting parts provided between the raw material supply holes and the molding grooves. The connecting parts each include, in a cross section substantially parallel to an extruding direction of the ceramic raw material, a curved part and a straight part.

Abstract: In a method of manufacturing a honeycomb structured body, a ceramic block is formed by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween. The multiple pillar-shaped honeycomb fired bodies are bound on a support by piling up the multiple pillar-shaped honeycomb fired bodies successively. A placing position where a primary honeycomb fired body is to be placed is determined. A position of an end face of at least one secondary honeycomb fired body is fixed by applying force to the end face of the at least one secondary honeycomb fired body. The primary honeycomb fired body is placed on the placing position with the position of the end face of the at least one secondary honeycomb fired body being fixed. The fixing further includes first positioning or second positioning based on a number of the at least one secondary honeycomb fired body before the fixing.

Abstract: A honeycomb structure includes a ceramic block. A plurality of honeycomb fired bodies include first-shaped units, second-shaped units, and third-shaped units. The first-shaped units include peripheral first-shaped units. Each of the peripheral first-shaped units is disposed in such a manner as to have two sides. One side of the two sides faces one of adjacent sides of one third-shaped unit among the third-shaped units with an adhesive layer therebetween. Another side of the two sides faces one of adjacent sides of another third-shaped unit among the third-shaped units with the adhesive layer therebetween. The two sides of each of the peripheral first-shaped units or extensions of the two sides are each neither substantially parallel nor substantially perpendicular to an extension of a second side and an extension of a first side of each of the second-shaped units.

Abstract: A honeycomb structure includes a ceramic block including honeycomb fired bodies. The honeycomb fired bodies include an assembly including a plurality of substantially quadrangular-cross-section units which are combined with one another with an adhesive layer interposed between the plurality of substantially quadrangular-cross-section units. A peripheral face of the assembly of substantially quadrangular-cross-section units has a concave portion and a convex portion formed in a substantially step-shaped pattern. At least one substantially triangular-cross-section unit has an outer wall on a periphery portion of the at least one substantially triangular-cross-section unit. The at least one substantially triangular-cross-section unit is fit in the concave portion with the adhesive layer interposed between the at least one substantially triangular-cross-section unit and the concave portion. A sealing material layer is provided on a peripheral face of the ceramic block.

Abstract: An image transmission device includes an image input unit that inputs a plurality of continuous images, a data amount reduction unit that reduces an amount of data of the plurality of images that are input to the image input unit, and generates a data amount reduced image, and a transmission unit that transmits the data amount reduced image to an image reception device that performs a recognition/authentication process with respect to the data amount reduced image. The data amount reduction unit reduces the amount of data of the plurality of images by a reduction method corresponding to the recognition/authentication process that is performed in the image reception device.

Abstract: A honeycomb structure includes a ceramic block including honeycomb fired bodies. The honeycomb fired bodies includes at least one first-shaped unit having a substantially quadrangular shape in a cross section perpendicular to the longitudinal direction. At least one second-shaped unit has a shape that includes at least a first side, a second side making a substantially right angle with the first side, and an inclined side facing the substantially right angle in the cross section.

Abstract: An object of the invention is to prevent an oil from penetrating into a vessel obtained from expandable thermoplastic resin beads through molding. The above object is achieved by expandable thermoplastic resin beads whose surface or surface layer is coated or incorporated with a fluorine-containing block copolymer comprising of a fluorine-containing vinyl-type polymer segment derived from a fluorine-containing vinyl-type monomer and a lipophilic vinyl-type polymer segment derived from a lipophilic vinyl-type monomer.
