The method of measuring angular velocity the method of forming the picture making use of the ink jet head and the ink jet head, making use of the angular velocity sensor and the angular velocity sensor and the generation of electricity method of using the piezoelectric generation of electricity element and the piezoelectric generation of electricity element

摘要

As for purpose of this invention, impressing the impression electric field above 40kV/cm, emission of the ink of the accurate quantity, measurement of accurate angular velocity, and the ink jet head whose the generation of electricity with the correct piezoelectric effect are possible, it is the angular velocity sensor, and to offer the piezoelectric generation of electricity element. The piezoelectric body membrane which is used for this invention the 1st electrode which puts piezoelectric body layer and particular piezoelectric body layer between and possesses the 2nd electrode, the 1st electrode (001) possesses orientation, piezoelectric body layer (001) has orientation, (1 z) (Na _{xBi y}) it is constituted from TiO_{0.5x+1.5y+2 zBaTiO3},As for x the 0.46 or less of 0.30 or more, as for y the 0.62 or less of 0.51 or more, as for z it is the 0.09 or less of 0.07 or more.
