Title: Oxygen concentration sensor
Inventor: KAMO TAKASHI
IPC: G01N27/12
Filed: 1986-05-14
Abstract: PURPOSE:To measure a lean area and a theoretical air/fuel ratio accurately, by forming on a cathode layer a gas diffusion layer composed of material which will change sharply in the electric resistance with the theoretical ratio as the turning point to build up a lean mixture sensor with the cathode layer and an anode layer. CONSTITUTION:Electrodes 2 and 3 composed of platinum or the like, having an emission cleaning catalytic action are formed on both sides of a planar solid electrolyte 1 comprising zirconia respectively. Then, a gas diffusion layer 4 composed of titanium is provided on the electrode 3 and further a heat resistant electrode 5 composed of platinum or the like is formed on the layer 4. Then, when a voltage is applied between the electrodes 2 and 3 with the electrode 3 as cathode, voltage/current characteristics are obtained and the proper selection of the voltage provides air/fuel ratio/current characteristics. As the layer 4 is made up of titanium, the resistance value thereof changes sharply with the theoretical air/fuel ratio of 14.6 as the turning point. Thus, discrimination can be done between a rich or lean level by detecting the resistance value lower or higher than a fixed value, thereby allowing the control of the theoretical air/fuel ratio. This enables the measurement of an air/fuel ratio and a theoretical air/fuel ratio in the lean area accurately.

Abstract: PURPOSE:To reduce the wiring between Josephson chips to one line and to decrease the wiring area by receiving a transmitted signal by a reception-side Josephson circuit, and decoding the states of the output signal of a transmission- side Josephson circuit and its complementary signal selectively according to whether the current value of the transmitted signal is large or not. CONSTITUTION:When signals sent from a transmission line are input signals A=1 and -A=0 from the transmission-side Josephson circuit, namely, when the value of a current inputted to a reception line 7 is large, the current flows to an output loop 8 to decode A=1 and no current flows to an output loop 49 to decode -A=0. Further, when the signals from the transmission line 6 are input signals A=0 and -A=1 to the transmission-side Josephson circuit, namely, when the value of the current inputted to the reception line 7 is small, the current does not flows to the output loop 48 to decode A=0, but flows to the output loop 49 to decode -A=1. Then, the output loops 48 and 49 are connected to the reception-side Josephson circuit and the output signals A and -A of the transmission side Josephson circuit are transmitted.
