摘要： An A/F ratio detecting arrangement includes a sensor casing having an oxygen sensor part arranged between first and second electrodes and an oxygen pump part arranged between third and fourth electrodes, which are heated by a heater. A signal output processing circuit serves to provide an A/F ratio signal. A signal switcher serves to provide a provisional oxygen content signal derived from the first and second electrodes when the oxygen pump part is not activated yet, and the A/F ratio signal when the oxygen pump part is activated.

摘要： A bent front wall 2a of a roof panel 2 is not bent at least inwardly of a press-worked direction of the roof panel 2, so that a front end of the roof panel 2 is free from undercut formation. This eliminates the necessity to further machine the front wall 2a of the press-worked roof panel 2, using for example a cam. Thus, manufacturing cost may be reduced without increasing man-hour.

摘要： In a heated type oxygen sensor having a sensing element responding to changes in the exhaust oxygen content and a heater inside, a diagnostic system for diagnosing deterioration of the heated type oxygen sensor comprises an electronic control unit being responsive to an engine temperature for discriminating whether the engine is in a cold-engine state or in a fully warmed-up state. The diagnostic system includes a first warm-up time setting circuit for setting a predetermined oxygen sensor's warm-up time at a first delay time which is preset to be suitable for the cold-engine state, during cold-engine operations, and a second warm-up time setting circuit for setting the predetermined oxygen sensor's warm-up time at a second delay time which is preprogrammed to be suitable for the fully warmed-up state, during fully warmed-up engine operations. The diagnostic system makes a diagnosis on deterioration of the oxygen sensor under a particular condition in which an elapsed time, measured from a time when the heater is turned on, reaches the predetermined oxygen sensor's warm-up time set depending on during cold-engine operation or during fully warmed up engine operation.

摘要： A system for preparing a self-hardening casting mold including a mass of sand which contains an organic binder and which has a pattern-contact layer having a surface for contact with a pattern disposed in a flask. The pattern defines a cavity into which a melt is poured to produce a cast product. The mold further includes a mass of ceramic balls placed on the pattern-contact layer of the sand mass. The system includes a temperature adjusting device for regulating the temperature of the mass of ceramic balls prior to introduction thereof into the flask, so as to control the hardening rate of mass of sand in the flask, a separating device operable on a mixture of sand and ceramic balls obtained from the mold after the cast product is produced by the mold with the pattern removed. The separating device separates the ceramic ball from the sand, and supplies the ceramic balls to the temperature adjusting device. The system further includes a sand reclaiming device for treating the separated sand to be reclaimed for preparing another casting mold.
