摘要： A composite ferrite material is provided. The composite ferrite material obtained from a mixture of a magnetic ferrite powder with high crystallinity, prepared by firing at a prescribed temperature, and a glass powder, having a softening temperature lower than said firing temperature, by heat treatment of said mixture at a temperature which is higher than, or equal to said softening temperature of said glass powder and lower than, or equal to said firing temperature, to effect the binding of said magnetic ferrite powder by said glass material. The composite ferrite material has excellent magnetic characteristics and can be obtained in a form of the desired dimensions with high accuracy.

摘要： 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.
