Patent number: 6464739Abstract: An anode for an electrolytic capacitor includes a porous body having micropores that include a dielectric layer filled thereon and an electrolyte filled therein. The porous body includes a laminate of a plurality of sinter layers having the micropores formed from valve metal particles. The laminate includes alternating smaller micropore-size regions and larger micropore-size regions, which form electric conductive passages between the smaller micropore-size regions and side surfaces of the porous body. This structure reduces resistance of the capacitor and also increases capacitance by effectively utilizing the capacitance of the smaller micropore-size regions. The porous body is formed by stacking a plurality of porous preforms, such as sheets preformed of valve metal powder, into a laminate, and then sintering the laminate. The porous body may be joined with a valve metal substrate during sintering, thereby completing the anode for an electrolytic capacitor.Type: GrantFiled: March 26, 2001Date of Patent: October 15, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tsunenori Yoshida, Kenji Hoshino, Masakazu Tanahashi, Yoshihiro Higuchi

Patent number: 5131273Abstract: An angular velocity sensor includes a pair of vibratory piezoelectric detecting elements defining detecting planes which are disposed in symmetry about a plane containing the sense axis and out of right-angled orientation with respect to this plane. The detecting elements thus arranged assume a widely spread or flattened V-shaped configuration as viewed from above. Output signals of opposite polarities received from the respective detecting elements are weighted respectively and added together so as to cancel out unwanted leak component signals. Thus, leak component signals resulting from assembling tolerances can be canceled. In this instance, if the characteristics of two sensor elements each including one of the detecting elements are fully equivalent, a leak component signal dependent on a disturbing inertial force can simultaneously be canceled out.Type: GrantFiled: July 6, 1990Date of Patent: July 21, 1992Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Munehiro Tabata, Suzushi Kimura, Tadashi Kawamata, Tsunenori Yoshida, Tomio Yoshida
