Abstract: In a microactuator device (2) having a cut face formed by cutting or splitting, the cut face is subjected to anti-release treatment for preventing release of particles produced by cutting. The microactuator device may have a multilayer structure including a plurality of piezoelectric elements and a plurality of internal electrodes alternately laminated. In this case, the multilayer structure has the above-mentioned cut face. It is preferable that the microactuator device is mounted between a base plate (3) to be fixed and a support spring (5) for supporting a head (4), and that the microactuator device and portions of the base plate and the support spring which are adjacent to the microactuator device are collectively coated with a coating film.

Abstract: A stacked-type capacitor with a fuse function for breaking an abnormal current wherein internal electrodes of a same polarity stacked in a ceramic body are led out to an outer surface of the ceramic body through lead-out electrodes. The lead-out electrodes have end surfaces exposed in the outer surface of the ceramic body. A film electrode for fuse function is formed on the outer surface to overlie the end surfaces of the lead-out electrodes and to be connected to an external electrode formed on the ceramic body. The film electrode is made from metallic powder and/or metallo-organic compound paste. The paste can contain powder of glass forming elements.

Abstract: The invention provides a method of manufacturing a laminated ceramic capacitor, which method includes a step of forming an electrically conductive paste layer on a green sheet composed of lead system composite perovskite oxide. The paste includes a solvent in which are distributed metal powder including at least silver powder, organic titanium compound, organic rhodium compound and organic binder. An amount of titanium in the paste preferably is in the range of 0.02% to 0.09% by weight on the basis of a weight of the metal powder, and an amount of rhodium in the paste preferably is in the range of 0.10% to 0.60% by weight on the basis of a weight of the metal powder.
