  • Method of manufacturing honeycomb structured body
    Patent number: 9199188
    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.

  • Press die for metal plate molding, the processing method of the surface of the press die, and manufacturing method of a vehicle body
    Patent number: 9126255
    Abstract: A press die and a processing method of the press die surface, and a manufacturing method of a vehicle body of an automobile, are capable of maintaining a high non-defective product rate of works after press processing, even in a case in which foreign matter such as iron filings and the like have adhered to a die surface. A press die for sheet metal forming has a multitude of concave portions on a die surface, and has a roughness (Ry) of a die surface on which the multitude of concave portions has been formed of 30 to 38 ?m.
