Patents by Inventor Takuya Fujimaru

Takuya Fujimaru has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electronic component and method of manufacturing the same
    Patent number: 6946945
    Abstract: In an electronic component, an element section is formed on a base, and the element section has functions of at least one of inductance, resistor, and capacitor. Resist film is formed on at least the lateral faces of the base. An unnecessary part of patterned resist film is removed, and a protective member is formed on that removed place. Then remaining resist film is removed. This manufacturing method can provide the electronic component excellent in bonding strength between the protective member and the base.
    Type: Grant
    Filed: October 1, 2002
    Date of Patent: September 20, 2005
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Satoshi Sato, Takuya Fujimaru, Yasuhiro Izumi, Yoshito Yoneda, Yasunori Tabaru, Yoshihiro Kiyomura

  • Dielectric ceramic composition
    Patent number: 5256639
    Abstract: A dielectric ceramic composition represented by the compositional formula: .sub.x BaO-.sub.y TiO.sub.2 -.sub.z Nd.sub.2 O.sub.3 -.sub.t Sm.sub.2 O.sub.3 -.sub.w Bi.sub.2 O.sub.3 so composed as to be in the molar fractions of 0.06.ltoreq.x.ltoreq.0.25, 0.60.ltoreq.y.ltoreq.0.80, 0.05.ltoreq.z.ltoreq.0.18, 0<t.ltoreq.0.07 and 0<w.ltoreq.0.05, provided that x+y+z+t+w=1, and a compositional range of Y<0.68 and Z>0.15 is excluded. As an additive, at least one of Al.sub.2 O.sub.3, ZrO.sub.2, etc. may be added. Part of Ba may be replaced with at least one of Sr, Ca and Mg. The Sm.sub.2 O.sub.3 and Nd.sub.2 O.sub.3 each may have a purity of at least 70 wt. %.

  • Dielectric ceramics
    Patent number: 5246898
    Abstract: High-frequency dielectric ceramics which contains the oxide of a complex perovskite structure as the main component, have a mean crystal gain size of sintered ceramic controlled to within the range of 5 .mu.m to 20 .mu.m and a porosity not exceeding 7% and provides high unloaded Q without requiring long-hour sintering or heat treatment.
