摘要： A heater pattern for a heater of a gas sensor in which a temperature profile is manipulated utilizes a thermistor element arranged in an electrically serial configuration and disposed on a substrate. The thermistor element is arranged so as to define an edge pattern extending about a perimeter of the substrate and a center pattern serially connected to the edge pattern. The center pattern extends over a portion of the substrate that is intermediate the perimeter of the substrate. In a preferred embodiment, the thermistor element is screen printed onto the substrate to a thickness of about 5 microns to about 50 microns, and preferably to a thickness of about 10 microns to about 40 microns. The edge and center patterns are furthermore preferably formed of materials having differing coefficients of thermal resistivity, e.g., platinum and platinum/palladium blends. A method of heating the gas sensor includes disposing the thermistor element in an electrically serial configuration about a perimeter of the substrate and over a portion of the substrate intermediate the perimeter of the substrate and pass an electric current through the thermistor element.

The housing has a first opening, which connects the interior to the exterior. The housing has one or more second openings, which lie deeper than the first opening so that a gas stream is driven by means of convection from the second opening to the first opening. The semiconductor gas sensor can be made of silicon by means of micro engineering.

摘要： An air-fuel ratio control system for a gas-fueled engine which is capable of achieving the combustion in a target air-fuel ratio to surely purify an exhaust gas through an exhaust purification catalyst. In the air-fuel ratio control system, a three-way catalytic converter is placed in an exhaust pipe of the engine and an O2 sensor is located on the upstream side of the three-way catalytic converter. The O2 sensor comprises an element, and an atmosphere side electrode is formed on an inner surface of the element while an exhaust gas side electrode is formed on an outer surface thereof. The exhaust gas side electrode is coated with a catalyst layer which can remove hydrogen through a catalytic reaction. A control unit of the control system controls a fuel supply quantity by a gas injector using a feedback correction coefficient on the basis of the output of the O2 sensor, thereby reducing the deviation between an air-fuel ratio measured by the O2 sensor and a target air-fuel ratio.

摘要： The chloride corrosion threshold of a metal embedded in a cementitious structure is determined in an accelerated manner by using an electric field to increase the rate of migration of chloride ion into the structure and monitoring the interface between the metal and the cementitious material to detect the onset of corrosion, then determining the chloride corrosion threshold, which is defined as the chloride content of the cementitious material once corrosion has begun. This determination can be performed over a time period of as little as 2 to 3 weeks rather than the months or years required by conventional chloride corrosion test procedures.
