Appeal No. 1996-3262
Application No. 08/141,632
Claim 1, following the preamble, recites "a diamond film
having a first surface and a second surface on an opposite side
of said first surface." Nakahata et al discloses38 a diamond
film 31 which has opposed upper and lower surfaces. The second
subparagraph of this claim recites "a resistor provided on said
first surface of said diamond film and measuring a temperature of
said diamond film." Semiconductor diamond film 32 of Nakahata
et al is on the upper surface of the diamond film 31 and measures
a temperature of said diamond film as it is connected thereto and
operates as a thermistor. The final subparagraph of this claim
recites "wherein at least said second surface is in contact with
the fluid in response to a temperature change of said diamond
film resulting from said heat transfer to sense a parameter of
the fluid." The lower surface of diamond film 31 of Nakahata's
thermistor is clearly exposed to contact with its environment and
the thermistor, in response to a temperature change in diamond
film 31 will sense a parameter of the environmental matter
surrounding it.
Nakahata et al also discloses39 that thermistors comprising
