Patent number: 7556792Abstract: Ba(OH)2.8H2O is fused by heating. The fused Ba(OH)2 is allowed to react with TiO2 powder having a specific surface area of 250 m2/g or more to prepare a cubic crystalline BaTiO3 having high crystallinity. The BaTiO3 is calcined to yield a fine, tetragonal crystalline BaTiO3 powder having high crystallinity. Thus, a high quality BaTiO3 having high crystallinity can be prepared at a low cost.Type: GrantFiled: December 30, 2002Date of Patent: July 7, 2009Assignee: Murata Manufacturing Co., Ltd.Inventors: Atsuhiro Torii, Shinichi Kato, Tomohisa Tonogaki, Masaru Kojima, Kenji Tanaka

Publication number: 20060046040Abstract: A composite laminate includes first sheet layers and second sheet layers. The first sheet layers include a first particulate aggregate and the second sheet layers include a second particulate aggregate. Each of internal second sheet layers is disposed between two first sheet layers and two external second sheet layers constitute two main faces of the composite laminate. The thickness of the internal second sheet layers is greater than the thickness of the external second sheet layers. The first sheet layers and the second sheet layers are bonded to each other by penetration of a part of the first particulate aggregate contained in the first sheet layers into the second sheet layers. This configuration can reduce the transverse shrinkage in the firing step of the composite laminate.Type: ApplicationFiled: October 3, 2005Publication date: March 2, 2006Inventors: Hirokazu Kameda, Shuya Nakao, Shigeyuki Kuroda, Masaru Kojima, Kenji Tanaka

Patent number: 5474488Abstract: An apparatus for forming input and output electrodes on the outer peripheral surface of a dielectric block coated with an electrically conductive film includes a holder for holding the block, a cutting tool with cutting surfaces, and a compression pump. Mobile tables supporting the holder and the cutting tool are controlled to cause the cutting surfaces to come in contact with a specified area on the outer peripheral surface of the block. Cutting water mixed with abrasive grains is projected by the compression pump onto the specified area, and ultrasonic vibrations generated by a vibration generator and amplified by an amplifier horn are transmitted to the cutter, causing a portion of the conductive film to be removed from a frame-shaped area, leaving an isolated piece of the conductive film separated from the remainder of the film to serve as an electrode.Type: GrantFiled: January 18, 1994Date of Patent: December 12, 1995Assignee: Murata Manufacturing Co., Ltd.Inventors: Yoshio Yamamoto, Kei Arai, Nobuyuki Hayashi, Masaru Kojima

Patent number: 5377406Abstract: A process for producing a printed circuit board is disclosed, in which use is made of a copper-clad laminate comprising a substrate and, superimposed thereon, a copper foil having its entire surface covered with a solder foil. A solder foil 4 is applied to cover the entire surface of a copper foil 2 superimposed on a substrate 1 (the copper foil 2 and the substrate 1 forming a copper-clad laminate 3). An etching resist is applied to the surface of the solder foil 4, and the solder foil 4 and the copper foil 2 are simultaneously etched to form a conductor circuit pattern 8. Thereafter, the etching resist is stripped off, and unneeded portions of the solder foil 4 are removed on the conductor circuit pattern 8 to thereby produce a printed circuit board. The above process of the invention facilitates soldering operation for the printed circuit board and reduces the production cost thereof.Type: GrantFiled: November 29, 1993Date of Patent: January 3, 1995Assignee: CMK CorporationInventors: Masuo Matsumoto, Naohiro Yoshida, Masaru Kojima
