    摘要: An air-fuel ratio in the lean range is detected by measuring a limiting current when oxygen diffused to a first electrode is pumped to a second electrode via a solid electrolyte. A stoichiometric air-fuel ratio is detected from electromotive force between first and third electrodes when oxygen is pumped from the first electrode to the third electrode. The invention is characterized by use of such three electrodes. Furthermore, an air-fuel ratio in a rich range is detected by either sending oxygen from the first electrode to the third electrode via the solid electrolyte and measuring a current when the electromotive force between the first and third electrodes is controlled to be constant, or measuring a current when the air-fuel ratio range is judged as "rich" from this electromotive force and the polarity of the impressed voltage at the time of lean detection is reversed.

    摘要: A device for supplying a cylindrical bottomed preform from an injection molding machine to a biaxial orientation blow molding machine, in which the pieces are conveyed in an upward opening attitude. The pieces are then inverted by an inverting table for inverting the piece from the upward opening to a downward opening attitude. The pieces are horizontally moved into piece guide recesses by an inserting plate and are dropped from the recesses to mandrels of the heat blow molding machine directly under the piece thus conveyed by a stopper plate to assemble the piece thus dropped with the mandrel for the biaxial orientation blow molding process.
