ELECTRODE FORMING METHOD FOR COLUMNAR PIEZOELECTRIC VIBRATOR AND VIBRATOR FOR PIEZOELECTRIC VIBRATION GYROSCOPE

摘要

PROBLEM TO BE SOLVED: To manufacture a columnar piezoelectric vibrator comprising strip-like electrodes all of which have uniform thickness, and to provide a piezoelectric vibration gyroscope using the columnar piezoelectric vibrator reduced in the irregularity of characteristics, especially in the irregularity of transmission characteristics.;SOLUTION: The electrodes of the columnar piezoelectric vibrator are formed by a screen printing method, and a plurality of strip-like patterns vertical to a printing direction are formed on a screen. The thickness of the emulsion at the portion on the surface of the screen excepting the insides of two straight lines, which respectively pass two outermost points in both directions of the printing patterns in the direction (widthwise direction) vertical to the printing direction among portions on the surface of the screen positioned on the side of a printing advance direction from the terminal lines of the finally printed strip-like pattern and the extention lines thereof, is made larger than that of the emulsion of other part.;COPYRIGHT: (C)2003,JPO
