摘要： Disclosed herein is a planar exhaust gas sensor for sensing the partial pressure of a gas in an exhaust. The sensing element has a modified, non-rectangular overall geometry. A terminal end of the element, onto which external sensor circuits can be attached, has a larger width than a sensor end of the element, in which is located the sensing cell. The reduced size of the sensor end of the element relative allows for more rapid attainment of operating temperature and lower energy consumption.

摘要： The invention includes a flat plate exhaust sensor including a flat plate sensing element which is carried by a first ceramic insulator having at its upper end an upwardly extending annular ring. The annular ring defines a disc-shaped recess which is filled with a glass seal. Thus, the glass seal extends from the flat plate sensor to the annular ring of the ceramic insulator. The sensor includes an upper tubular shell which includes at the lower end a leg portion which extends inside an inner wall of a lower tubular shell. The leg portion includes a foot which is bent to match an outwardly extending sloped annular shoulder formed on an upper insulator. The upper insulator is seated on the glass seal. An intermediate gasket is formed by an active metal braze gasket between the foot and the outwardly extending sloped annular shoulder of the upper insulator. An external seal is provided by a braze ring which joins an upper end of the lower tubular shell to the upper tubular shell. The system removed the thermal expansion mismatch problems of prior art glass seal sensors.

摘要： A method of fabricating a lapping carrier is provided that includes the steps of defining at least one opening extending through a workpiece that is sized to receive a wafer, and cryogenically tempering the workpiece to produce a lapping carrier. By cryogenically tempering the workpiece, the conversion of the crystalline structure of the workpiece to a martensite crystalline structure is enhanced, thereby improving the hardness of the lapping carrier. A lapping carrier is also provided that has a crystalline structure, of which at least 70% is a martensite crystalline structure. An apparatus for lapping a wafer is further provided that includes a hardened lapping carrier and at least one lapping plate proximate the lapping carrier for lapping wafer(s) disposed within the at least one opening defined by the lapping carrier.
