Application No. 09/085,300
orifice for an entire lot of sensor elements is determined by
correlating an optimum pump current value with the measured pump
current and the diameter of the intake orifice of the selected
sensor element. The diffusion resistance of a diffusion barrier
of the sensor elements is adjusted by modifying the diameter of
the gas intake orifice in accordance with the determined optimum
gas intake orifice diameter.
Claim 7 is illustrative of the invention and reads as
follows:
7. A method of calibrating sensor elements for limit
current probes, comprising the steps of:
(a) measuring a value of a pump current of one of the
sensor elements at a selected pump voltage, a gas intake
orifice of the one of the sensor elements having a
predetermined diameter;
(b) correlating the measured value of the pump current
with the predetermined diameter of the gas intake orifice
and an optimum pump current; and
(c) calibrating the sensor elements as a function of
the correlating step, the calibrating step being performed
during a manufacturing process of the sensor.
No prior art references have been relied upon by the
Examiner.
As the sole rejection by the Examiner before us, claims 7-
10, 12, and 14-19 stand finally rejected under 35 U.S.C. § 112,
first paragraph, as being based on an inadequate disclosure.
