Method of Examination
Resistance value is measured by applying voltage under 1.5Vdc
(by a direct current of less than 10mA) in a silicone oil vessel.
We apply AC voltage 120% that of the maximum voltage to

The load is gradually applied to each terminal of POSISTOR r
until 9.80N in the axial-direction with fixing POSISTOR r 's body
itself and this load is kept for 10 seconds.
POSISTOR r is held so that it is perpendicular to the lead wire
with the following load hanging in the axial direction of the lead
wire. The lead wire is slowly bent to 90° and returned; then it is
