Claim 1
Independent Claim
130 words
A method of making a thermistor, comprising: making a layer of thermistor ceramic material having upper and lower surfaces; placing a first dielectric material on said upper and lower surfaces of said layer, cutting said layer into a plurality of elongated strips with dielectric material on the upper and lower surfaces, and with sides and ends thereof being exposed, placing a second dielectric material on said exposed sides of said strips, wherein said first and second dielectric materials form an insulating and chemical resisting envelope over said upper and lower surfaces and sides of each said strip; and placing conductive terminals over the ends of said strips by placing on the ends thereof successive layers of silver, Ni, Sn, and Pb with portions of the terminals extending over the envelope.
Claim 2
Independent Claim
130 words
A method of making a thermistor, comprising: making a layer of thermistor ceramic material having upper and lower surfaces; placing a first dielectric material on said upper and lower surfaces of said layer, cutting said layer into a plurality of elongated strips with dielectric material on the upper and lower surfaces, and with sides and ends thereof being exposed, placing a second dielectric material on said exposed sides of said strips, wherein said first and second dielectric materials form an insulating and chemical resisting envelope over said upper and lower surfaces and sides of each said strip; and placing conductive terminals over the ends of said strips by placing on the ends thereof successive layers of silver, Ni, Sn, and Pb with portions of the terminals extending over the envelope.
Claim 3
Independent Claim
157 words
A method of making a thermistor, comprising: making a layer having upper and lower surfaces from a slurry material comprised substantially from one of Mn 2 O 3 ,NiO, Co 3 O 4 , Al 2 O 3 , CuO, and Fe 2 O 3 ; placing a first dielectric material on said upper and lower surfaces of said layer, cutting said layer into a plurality of elongated strips with dielectric material on the upper and lower surfaces, and with sides and ends thereof being exposed, placing a second dielectric material on said exposed sides of said strips, wherein said first and second dielectric materials form an insulating and chemical resisting envelope over said upper and lower surfaces and sides of each said strip; and placing conductive terminals over the ends of said strips by placing on the ends thereof successive layers of silver, Ni, Sn, and Pb with portions of the terminals extending over the envelope.
Claim 4
Independent Claim
157 words
A method of making a thermistor, comprising: making a layer having upper and lower surfaces from a slurry material comprised substantially from one of Mn 2 O 3 ,NiO, Co 3 O 4 , Al 2 O 3 , CuO, and Fe 2 O 3 ; placing a first dielectric material on said upper and lower surfaces of said layer, cutting said layer into a plurality of elongated strips with dielectric material on the upper and lower surfaces, and with sides and ends thereof being exposed, placing a second dielectric material on said exposed sides of said strips, wherein said first and second dielectric materials form an insulating and chemical resisting envelope over said upper and lower surfaces and sides of each said strip; and placing conductive terminals over the ends of said strips by placing on the ends thereof successive layers of silver, Ni, Sn, and Pb with portions of the terminals extending over the envelope.
Claim 5
Independent Claim
42 words
The method of claims 1 or 2 including after placing each of said layer of silver, subjecting said strip to heat in the range of 100°-300° C. for 5-35 minutes, and then firing at a temperature of 500°-700° C. for 5-25 minutes.
