摘要： An air-fuel ratio feedback correction coefficient for correcting a fuel supply quantity to an engine is proportional-plus-integral controlled based on an output from an oxygen sensor for detecting oxygen concentration in the exhaust gases. When the oxygen sensor is in an inactive condition, deviation of an air-fuel ratio control point in the air-fuel ratio feedback control is detected, and an operating quantity in the proportional-plus-integral control is corrected so as to reduce the detected deviation.

摘要： In a device having air-fuel ratio sensors upstream and downstream of an exhaust gas purifying catalytic converter with learning carried out based on output values from the downstream air-fuel ratio sensor, independent learning is carried out depending on whether the catalytic converter is active or not. The air-fuel ratio is then controlled based on the output value of the first air-fuel ratio sensor, the output value of the second air-fuel ratio sensor and the learned value. As a result leaning accuracy is increased and air-fuel ratio control performance enhanced.

摘要： With an air-fuel ratio control apparatus for an internal combustion engine wherein oxygen sensors are respectively arranged upstream and downstream of an exhaust gas purification catalytic converter, air-fuel ratio feedback control is carried out for diagnosis using only the downstream oxygen sensor. When during diagnostic air-fuel ratio feedback control, phase differences of output fluctuations of the two oxygen sensors are below a predetermined value, deterioration of the catalytic converter is judged. A judgment level is variably set based on the results of the deterioration diagnosis of the catalytic converter, and deterioration of response of the downstream oxygen sensor is diagnosed by comparing the output-period of the downstream oxygen sensor with the set judgment level.

摘要： With a V type engine, the exhaust air-fuel ratio is detected for each bank, and is also detected downstream of a catalytic converter which takes the combined exhaust flow from each bank. An air-fuel ratio feedback correction coefficient .alpha. is proportional-plus-integral controlled separately for each of the banks based on the air-fuel ratio detected for each of the banks, while a correction value PHOS for a proportional portion is set commonly for each of the banks, based on the air-fuel ratio detected downstream of the catalytic converter. Here the correction value PHOS is converted to separate correction values PHOSR, PHOSL for each of the banks corresponding to a change rate of the air-fuel ratio feedback correction coefficient .alpha. to an initial value, and the proportional operating amount of the proportional-plus-integral control which is carried out separately for each bank, is corrected based on the converted correction values PHOSR, PHOSL.With such construction, the proportional operating amount can be suitably corrected corresponding the difference in the base air-fuel ratios occurring between the banks, so that the air-fuel ratio of each bank can be controlled to a high accuracy.

摘要： A quartz glass crucible adapted for use in a process for pulling a single crystal semiconductor material having an opaque outer substrate of a quartz glass with a relatively high bubble content and an inner transparent glass layer which is substantially free from bubbles. The crucible is produced while the substrate is supported by a rotating mould by forming an atmosphere of high temperature gas and supplying a metered quantity of powders of quartz to the high temperature gas atmosphere to have the quartz powders molten at least partly and directed toward an inner surface of the substrate to be adhered thereon.

摘要： An oxygen sensor includes a base body portion; and a plurality of function layers laminated on a surface of the base body portion. The function layers includes a solid electrolyte layer adapted to conduct oxygen ions; a reference electrode layer located on a base body portion side of the solid electrolyte layer; a sensing electrode layer located on the opposite side of the solid electrolyte layer to the reference electrode layer; a heater portion adapted to activate the solid electrolyte layer by heating; and a gas diffusion layer formed between the reference electrode layer and the base body portion, and adapted to diffuse a reference gas within the gas diffusion layer. The gas diffusion layer is formed to have a porosity indicating a limit current value ranging between 60 μA and 200 μA. The limit current value is a value of a current flowing between the reference electrode layer and the sensing electrode layer when the current flowing therebetween becomes substantially constant during the process of bringing a voltage applied therebetween higher.

摘要： A first pipe 231 and a second pipe 232 are connected using connectors 233 and 234 so that at least one of the connectors 233 and 234 is located in a through-hole 133. In this way, since the through-hole 133 is filled in by at least one of the connectors 233 and 234, the gap between the connectors 233 and 234 and the edge of the through-hole 133 can be considerably reduced. It is, therefore, possible to prevent hot air from moving to the front of a panel 100 through the gap between connectors 233 and 234 and the edge of the through-hole 133.
