摘要： A semiconductor ceramic for thermistors contains zinc oxide and titanium oxide as main components and a predetermined content of manganese. Also, a chip-type thermistor including the semiconductor ceramic is provided. By adding manganese, the resistance-temperature characteristic is controllable in the range of positive temperature coefficient to negative temperature coefficient. Also, by adding nickel, the resistivity is controllable. As a result, a thermistor material which provides a series of semiconductor ceramics having various resistivities and various B constants in a low range, for example 0 to 1,000 K, is available.

摘要： A negative temperature coefficient thermistor includes a thermistor element containing a transition metal oxide as a main component; internal electrodes disposed in the thermistor element; and external electrodes, electrically connected to the internal electrodes. A method for manufacturing such a thermistor includes providing green ceramic sheets for forming the thermistor element; applying a conductive paste for forming the internal electrodes onto some of the green ceramic sheets to form internal electrode layers; stacking the green ceramic sheets and the green ceramic sheets with the paste to form a green compact; firing the green compact to obtain a fired compact; and forming the external electrodes.

摘要： An electromechanical transformation device comprises an alkaline niobate piezoelectric ceramic composition and a rigid body adhered onto the major surface of the piezoelectric ceramic composition. The piezoelectric ceramic composition is made of crystal structures such as orthorhombic crystals formed at the side where the temperature is lower than the orthorhombic-to-tetragonal phase transition temperature, tetragonal crystals formed at the side where the temperature is higher than the orthorhombic-to-tetragonal phase transition temperature as well as at the side where the temperature is lower than the tetragonal-to-cubic phase transition temperature, and the cubic crystals formed at the side where the temperature is higher than the tetragonal-to-cubic phase transition temperature. Young's modulus of the rigid body is 60 GPa or more and the volume percent of the piezoelectric ceramic composition existing within a range where the distance from the adhesion point of the piezoelectric ceramic composition and the rigid body is 40% or more.
