    摘要: A substrate for a hybrid IC comprises a substrate (1), a thick film resistor (3) containing glass, formed on the substrate (1), and a thick film conductor (2) at the terminal of the thick film resistor (3). A means for preventing diffusion of the glass from the thick film resistor (3) into the thick film conductor (2) is provided between the thick film resistor (3). This means may be a compound added to the paste used for forming the thick film resistor (3) or may be a paste of metallic powder applied to the terminal of the thick film conductor (2). The thick film conductor (2) has a stable resistance as a thick film microresistor and may be applied to various uses such as cellular radio communication system.

    摘要: An air-fuel ratio in the lean range is detected by measuring a limiting current when oxygen diffused to a first electrode (123; 2; 51) is pumped to a second electrode (124; 3; 52) via a solid electrolyte. A stoichiometric air-fuel ratio is detected from electromotive force between first (123; 2; 51) and third electrodes (126; 6; 53) when oxygen is pumped from the first electrode (123; 2; 51) to the third electrode (126; 6; 53). 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 (123; 2; 51) to the third electrode (126; 6; 53) via the solid electrolyte (127; 1; 50) 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.
