STATIC CAPACITANCE TYPE PICKKUP STYLUS AND PRODUCTION OF SAME

摘要

PURPOSE:To simplify fabrication processes and reduce costs for a static capacitance type pick-up stylus by making a small piece of a sapphire single crystal rod having a small piece of a sapphire signal crystal rod having a main crystalaxial in a direction perpendicular to the longitudinal direction of the rod, which is cut in its longitudinal direction, as the entire part of the stylusm and providing an electrode directly to said crystal.
