摘要： A nonlinear resistor comprising a sintered body containing zinc oxide as a major component and at least bismuth oxide and boron oxide and electrodes formed thereon, said sintered body having a higher .gamma.-form bismuth oxide phase concentration in upper and/or lower surface layers of the sintered body than in the inner portion of the sintered body, has stabilized properties against long-time voltage application. When the sintered body is further modified by making the .gamma.-form bismuth oxide phase concentration in the periphery portions of the upper and/or lower surface layers lower than that in the inner portions of the upper and/or lower surface layers, the resulting nonlinear resistor shows a higher long-duration current impulse withstand capability.

摘要： A ferroelectric element is provided that can be highly densely integrated having a high Pr and a small Ec by using a ferroelectric thin film of the perovskite structure. A large distortion is imparted to the crystalline lattices of a ferroelectric thin film of the perovskite structure by using in combination elements having dissimilar ionic radii for the A-site that constitutes crystalline lattices, for the B-site and for the C-site that produces polarization, in order to obtain a ferroelectric element of a structure in which the ferroelectric thin film exhibiting a high spontaneous polarization and a small coersive electric field is sandwiched by the electrodes.

摘要： A non-linear resistor having a high impulse withstanding ability is obtained by directly applying a crystallized glass to the side surface of a sintered body of a ZnO element, and then bake-attaching the crystallized glass to the side surface of the ZnO element by heat treatment. Since the impulse withstanding ability is improved by applying the crystallized glass as the side surface high-resistivity layer of the voltage non-linear resistor, the performance and reliability of an arrester including the resistor is improved.
