Patent number: 8154204Abstract: A plasma display panel includes a front plate having a dielectric layer covering a display electrode formed on a substrate and a protective layer formed on the dielectric layer, and a rear plate facing the front plate so as to form a discharge space. The plasma display panel also includes an address electrode in a direction crossing the display electrode, barrier ribs for partitioning the discharge space, and phosphor layers. The protective layer is constructed by forming a ground film on the dielectric layer and adhering agglomerated particles to the ground film. The agglomerated particles are produced by coagulating a plurality of crystal particles made of metal oxide.Type: GrantFiled: April 20, 2009Date of Patent: April 10, 2012Assignee: Panasonic CorporationInventors: Kaname Mizokami, Hiroshi Sogou, Shigeyuki Okumura

Patent number: 6326694Abstract: A printed circuit board includes an uncured substrate material with closed voids which are disposed with a through-hole. When the through-hole is formed, voids which exist in the substrate material open from inner wall of the through-hole to form a hollow-shaped part. By filling the through-hole and the hollow-shaped part with conductive paste, the adhesion improves by the increased holding effect between the conductive paste and the wall surface of the through-hole.Type: GrantFiled: June 21, 1999Date of Patent: December 4, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akihito Hatakeyama, Seiichi Nakatani, Kouji Kawakita, Hiroshi Sogou, Tatsuo Ogawa, Tamao Kojima
