    摘要: A terminal member (120) for an electrolyte sensor (24) having a first diameter section (122) separated from a second diameter section (124) by a shoulder (126). A stepped axial bore (138) extends from a second end (134) forward a first end (132). First and second passages (128 and 130) extend from the first end (132) to the second end (134). An axial slot (136) extends through the second diameter (124) to the stepped axial bore (138). First and second grooves (156 and 158) located on the periphery of the first diameter (122) extend to a first radial slot (160). A second radial slot (162) is offset from the first radial slot (160). The first and second radial slots (160 and 162) position terminals (164 and 164') connected to a heater member (92) located in bore (138) while first and second contact rings (142 and 144) are located on shoulder (126) and (140) to provide isolation for electrical paths between an external surface (80) and internal surface (82) of an electrolyte sensor (24).

    摘要: A glow plug has a heater member form by depositing a continuous metallic-silicide layer on the internal and external surfaces of a hollow open-ended cylindrical ceramic substrate. The metallic-silicide layer on the external surface of the substrate is electrically connected to a metal shell which supports one end of the heater member. An axial electrode disposed in the shell is electrically connected to the metallic-silicide layer disposed on the internal surface of the substrate and further serves together with a shoulder on the heater member to lock the heater member in the shell. The metallic-silicide resistive layer has a positive temperature coefficient of resistance and is substantially uneffected by micro-irregularities on the substrate surfaces to provide a cold resistance of from 0.2 to 0.6 ohms and is capable of responding to five amperes of current to develop a temperature of at least 800.degree. C. within five seconds.

    摘要: A temperature compensated oxygen sensor has a generally cylindrical first insulator with an axial bore extending therethrough which is counterbored at one end. A second cylindrical insulator is retained in the bore in the first insulator either by a radial inwardly directed flange on the second end of the first insulator or by a radial outwardly directed flange on one end of the second insulator which seats in the counterbore of the first insulator. A titania resistor and a compensating resistor are mounted on the second end of the second insulator by leads extending through longitudinal bores in a second cylindrical insulator and into the counterbore in the first insulator. The leads are connected to terminals which are retained in the counterbore either by a chemical bonding agent or by a third cylindrical insulator through which the terminals extend. The third insulator can be secured either by mechanical means and/or by a chemical bonding agent including a glass preform.
