Patent number: 9240333Abstract: In a manufacturing method for a monolithic ceramic electronic component, a plurality of green chips arrayed in row and column directions which are obtained after cutting a mother block are spaced apart from each other and then tumbled, thereby uniformly making the side surface of each of the green chips an open surface. Thereafter, an adhesive is applied to the side surface. Then, by placing a side surface ceramic green sheet on an affixation elastic body, and pressing the side surface of the green chips against the side surface ceramic green sheet, the side surface ceramic green sheet is punched and stuck to the side surface.Type: GrantFiled: August 8, 2014Date of Patent: January 19, 2016Assignee: Murata Manufacturing Co., Ltd.Inventors: Togo Matsui, Minoru Dooka, Hiroyoshi Takashima, Kenichi Okajima

Patent number: 7950326Abstract: In a print area provided on a peripheral surface of a gravure roll, a plurality of cells are defined by printing-direction walls and perpendicular walls, and each perpendicular wall has a plurality of cuts. In a center portion of the print area, most intersections of the printing-direction walls and the perpendicular walls are defined by T-shaped intersections where the perpendicular walls do not cross the printing-direction walls, but meet the printing-direction walls in a T-shaped arrangement. Preferably, round chamfers are provided at corners where a portion of each printing-direction wall and a portion of each perpendicular wall intersect, and at leading ends of the perpendicular walls pointing toward the cuts.Type: GrantFiled: September 17, 2008Date of Patent: May 31, 2011Assignee: Murata Manufacturing Co., Ltd.Inventors: Hiroyoshi Takashima, Akira Hashimoto, Kazuhiro Tabata, Yoshihiro Kanayama, Takashige Tanabe

Patent number: 7547370Abstract: A method for manufacturing a multilayer ceramic electronic element includes the steps of forming ceramic green sheets having superior surface smoothness and small variations in thickness at a high speed, in which defects such as pinholes are prevented from occurring, and providing internal electrodes and step-smoothing ceramic paste on the ceramic green sheets with high accuracy. The method includes the steps of applying ceramic slurry to a base film by a die coater followed by drying performed in a drying furnace for forming the ceramic green sheets, and performing gravure printing of conductive paste and ceramic paste onto the ceramic green sheets by using a first and a second gravure printing apparatus, respectively. Accordingly, the internal electrodes are formed, and the step-smoothing ceramic paste is provided in regions other than those in which the internal electrodes are formed.Type: GrantFiled: December 15, 2006Date of Patent: June 16, 2009Assignee: Murata Manufacturing Co., Ltd.Inventors: Shingo Okuyama, Hiroyoshi Takashima, Akira Hashimoto, Shinichi Kokawa
