摘要： [Objective] An object is to provide a sensor control apparatus and a sensor-control-apparatus control method which can reduce variation in startup time among a plurality of times of execution of detection processing, in consideration of variation in output characteristic among a plurality of gas sensors.[Means for Solution] In a sensor control apparatus, before drive control (S55 to S80) is started, preliminary control is executed so as to supply a constant current to a second oxygen pump cell over a constant time, to thereby control to a constant level the amount of oxygen pumped from a second measurement chamber to the outside of the second measurement chamber (S40 to 50). The preliminary control is executed under control conditions of the sensor control apparatus which are determined for each gas sensor and are associated with the amount of oxygen pumped from the second measurement chamber to the outside thereof. The control conditions bring into a target range the concentration correspondence value calculated after start of the drive control which is started after the preliminary control is executed in a state in which a reference gas having a known concentration is introduced into the gas sensor.

摘要： A gas sensor controller 190 stops an operation of pumping in or out oxygen that is being performed by a first pump cell 111 in a state that the oxygen concentration (oxygen partial pressure) of a gas to be measured is equal to a status judgment reference value (20%). The gas sensor controller 190 calculates an oxygen pressure in a second measurement chamber 161 on the basis of a second pump current Ip2. If the oxygen pressure in the second measurement chamber 161 is equal to a deterioration judgment reference value, the gas sensor controller 190 judges that the second pump cell 113 is in a normal state. If the oxygen pressure in the second measurement chamber 161 is different from the deterioration judgment reference value, the gas sensor controller 190 judges that the second pump cell 113 is in a deteriorated state.

摘要： In a gas sensor element of a gas sensor, reference oxygen chamber (113) assumes the shape of a rectangular parallelepiped. A reference electrode (111) is disposed on a surface of a third solid electrolyte body (73) which is exposed to the reference oxygen chamber (113). A second outer electrode (117) is disposed opposite the reference electrode, on a surface of a second solid electrolyte body (77) which is exposed to the reference oxygen chamber. Further, a porous, insulative protection layer (165) is formed so as to cover the entire surface of the second outer electrode. A gap (167) is present between the reference electrode and the insulative protection layer. The thickness of the gap is greater than that of the insulative protection layer.

摘要： An authentication system 100 includes an authentication server 10 and a service providing server 20 for providing a service. When a user requests authentication, the authentication server lets the user input login information, transmits the login information to the service providing server 20, and calculates a first hash value from the login information using a hash function. The service providing server 20 calculates a second hash value from the login information using the same hash function if the login information transmitted from the authentication server 10 matches information that is registered in advance. The authentication server 10 establishes a session with a terminal 30 if the first hash value and the second hash value match each other.

摘要： In a sensor diagnosis process, a controller for controlling an NOx gas sensor performs processing of changing the oxygen partial pressure in a second measurement chamber by changing the oxygen partial pressure in a first measurement chamber (S190), processing of detecting a current flowing through a second pump cell before the change of the oxygen partial pressure (S180), and processing of detecting a current flowing through the second pump cell after the change of the oxygen partial pressure (S230). Furthermore, the controller performs processing of judging whether or not the ratio between the current values detected by the respective current detecting unit falls within an allowable range, judging that the second pump cell 113 is in a normal state if the ratio between the current values falls within the allowable range, and judging that the second pump cell 113 is in a deteriorated state if the ratio between the current values is out of the allowable range (S240 and S250).
