    Abstract: This invention provides an anodic electrode for an electrolytic capacitor having high capacitance with low-resistance properties at high frequencies and is capable of carrying large current, and a process of producing the same. Such an anodic electrode for electrolytic capacitor includes a porous body that have micropores to be formed with dielectric layer therein and to be filled with electrolyte therein, wherein the porous body includes a laminate of a plurality of sinter layers having the micropores formed from valve metal particles. The laminate includes multilaminarly smaller micropore-size regions and larger micropore-size regions to form electric conductive passages between the smaller micropore-size regions and side surfaces of the porous body to reduce resistance of the capacitor and also increase capacitance by utilizing the smaller micropores-size regions for capacitor effectively. 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 anodic electrode for an electrolytic capacitor. Particularly, the porous body may be a laminate including large micropore-size sinter layers and small micropore size sinter layers, by alternatively laminating two types of preforms different in its density.

    Abstract: An angular velocity sensor (10) includes a pair of vibratory piezoelectric detecting elements (11a, 11b) whose detecting planes (D1, D2) are disposed in symmetry about a plane (S) containing the sense axis (18) and out of right-­angled orientation with respect to this plane (S). 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 can be offset. In this instance, if the characteristics of two sensor elements (17a, 17b) each including one of the detecting element are fully equivalent, a leak component signal dependent on a disturbing inertial force can simultaneously be canceled out. With this construction, the variation of the offset voltage can be reduced even when the sensor is subjected a great change in environmental conditions including tempera­ture.
