摘要： PROBLEM TO BE SOLVED: To hardly receive an influence of a noise due to a reflection of an ultrasonic wave from a mounting part when an element such as an ultrasonic element is mounted at a measuring part in a sensor which houses the element such as the ultrasonic element or the like. SOLUTION: A detecting element body 40 houses a piezoelectric element 51 in the housing part 43 of a case 42, and is mounted in a housing part 22 of a channel forming member 20. Thus, a route length from the element 51 to a mounting position of the body 40 becomes long, the ultrasonic wave leaked from the element 51 into the body 40 is reflected at a connecting part and is hardly returned. Accordingly, the influence of the noise or the like due to the reflected wave is reduced, and hence a detecting accuracy is improved. A clearance of 1 mm or more is provided averagely on an outer periphery of the part 43 of the body 40, and accordingly a problem of the residue of a foreign matter hardly occurs.

摘要： PROBLEM TO BE SOLVED: To identify the details and occurrence positions of abnormality, without making a sensor element damaged, when an abnormality occurs in a gas concentration measuring device employing a gas sensor such as a whole region air-fuel ratio sensor, an NOx sensor or the like. SOLUTION: At the voltage value of a connection point connecting the sensor element 10 to a sensor element control circuit 50 becoming an abnormal voltage value being previously set, when the gas concentration measuring device 1 is in its operation state, the sensor element control circuit 50 is shut off from each connection point. Accordingly, abnormal current flowing in the sensor element 10 is blocked at an abnormality occurrence timing, thereby preventing the sensor element 10 from damaging. Then, the sensor element control circuit 50 supplies the sensor element 10 with current, whose level will not cause the sensor element 10 to damage, and detects voltage values of respective connection points. The details and occurrence locations of the abnormality in the sensor element 10 are identified, based on respective terminal voltage values detected at the connection points.

摘要： PROBLEM TO BE SOLVED: To provide a gas sensor capable of miniaturizing the whole device, by miniaturizing a measuring chamber for measuring the gas concentration of evaporating fuel or the like, using ultrasonic waves.
SOLUTION: The measurement chamber 30 on this gas sensor 1 is separated into a measuring chamber upper part 31 and a measuring chamber lower part 32 by reflecting plates 18, 19 tilted downwardly by 45 degrees. A purge gas has a passage from a gas inflow hole 28 to a gas outflow hole 29 via the measuring chamber lower part 32, and replacement of the gas in the measuring chamber upper part 31 is performed via an interval between each tip part 22, 23 of the reflecting plates 18, 19 or via a clearance with the sidewall of a casing 2. The ultrasonic waves, transmitted from an ultrasonic element 10, enter a reflecting surface 17 via reflecting surfaces 15, 16, and are reflected in the same axial direction. The reflected waves follow the same path as the propagation path of the transmitted waves, and are received as received waves by the ultrasonic element 10. By not providing a partition wall in the measurement chamber 30, the propagation path of the ultrasonic waves is not formed linearly, and the measuring chamber 30 is miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a pseudo signal generating device for a gas sensor, precisely and in a pseudo manner generating a delay state of a detection signal output in a state where the gas sensor is deteriorated.
SOLUTION: Until T5 timing where a first delay signal (a voltage value VipLR[LRw]) delayed by LR time from a reference signal intersects with a second delay signal (a voltage value VipRL[RLw]) delayed by an RL time longer than the LR time, the first delay signal is output as a pseudo signal. Since the voltage value after the T5 timing tends to be lowered, the second delay signal is selected as a pseudo signal. However, the second delay signal indicates a value from the T5 timing to the T7 timing, larger than the voltage value (lean same reference value) at the T5 timing, and the lean same reference value is output as a pseudo signal during the time.
