摘要： A gas sensor control apparatus for controlling a gas sensor includes a resistance detection unit and a heater control unit. The resistance detection unit detects a resistance of an object cell of the gas sensor. When the resistance of the object cell is lower than a predetermined threshold, the heater control unit controls energization of a heater such that the resistance detected by the resistance detection unit is a first predetermined resistance. Subsequently, after elapse of a predetermined time, the heater control unit further controls energization of the heater in such a manner that the resistance detected by the resistance detection unit is a second predetermined resistance of a resistance value that is higher than that of the first predetermined resistance.

摘要： A NOx sensor includes a sensor element equipped with first and second pumping cells to define first and second measurement chambers. The first pumping cell exerts an oxygen pumping action against the first measurement chamber to adjust the oxygen concentration in the gas under measurement within the first measurement chamber to a given level. The second pumping cell exerts an oxygen pumping action against the second measurement chamber to produce a pumping cell current according to the NOx concentration in the gas under measurement. When the moisture content of the gas under measurement changes from 2 vol % to 8 vol %, the NOx sensor allows a variation of NOx concentration detection value based on the pumping cell current in such a manner that the NOx concentration detection value reaches a transient peak value of 20 ppm or smaller and converges to ±5 ppm of a reference value within 5 seconds.

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.
