<p>PURPOSE:To suppress fluctuation of capacitance when adjusting electrostatic capacitor or the deviation (setting drift) of electrostatic capacitance after adjustment due to the applied pressure of a sorew driver or its insertion angle into a screw driver groove. CONSTITUTION:Whether this capacitor itself looks like to form a movable electrode or it has rotor 5 containing a movable electrode, a screw driver groove 10 is provided on its surface to fit a turning tool such as a screw driver. And the bottom of this groove is protruded at its center A higher than its ends B, C, D, and E. Further, whether this capacitor itself makes up a movable electrode or it has a rotor 11 containing a turning electrode, a screw driver groove 10 is provided on its center axis to engage a turning tool such as a screw driver 13, and its center A is raised higher than its ends B-E.</p> |
