Patent number: 6469516Abstract: In a method for judging the conformity or non-conformity of a capacitor from the charging characteristic at the time when a direct-current voltage is applied to the capacitor, a threshold current value I0 of the dielectric polarization component of the capacitor is determined in advance, an evaluation function n(t) is determined based on a logarithmic value of the difference between the measured charging current value m(t) of the capacitor and the threshold current value I0 or the difference between their logarithmic values, and the evaluation function n(t) is approximated to a quadratic curve. When the quadratic coefficient of the quadratic approximation equation has a plus sign the capacitor is judged to be non-conforming, and when the coefficient has a minus sign, the capacitor is conforming.Type: GrantFiled: November 17, 1999Date of Patent: October 22, 2002Assignee: Murata Manufacturing Co., Ltd.Inventors: Yoshinao Nishioka, Mitsuru Kitagawa

Patent number: 6204638Abstract: A capacitor can be charged at a high speed by applying a direct current voltage intermittently to the capacitor. The direct current voltage is intermittently applied to the capacitor such that a preceding applied voltage E1 is larger than a succeeding applied voltage E2. Thus, the charging is swiftly progresses and the capacitor can be charged at a higher speed than when the voltage is applied continuously.Type: GrantFiled: January 6, 1998Date of Patent: March 20, 2001Assignee: Murata Manufacturing Co., Ltd.Inventors: Yoshinao Nishioka, Toshinari Tabata
