Abstract: PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device for an exhaust emission control device, diagnosing the presence or absence of abnormality regarding the exhaust emission control device employing a method for absorbing and removing a specific component in exhaust gas by using absorbing liquid. SOLUTION: This abnormality diagnostic device for an exhaust emission control device is applied to exhaust emission control devices 20, 30 which hold the absorbing liquid absorbing the contacted specific component when the absorbing liquid is brought into contact with the specific component (for example, NOx and CO2) in the exhaust gas, which are arranged in an exhaust pipe 11, and which absorb and remove the specific component by bringing the absorbing liquid into contact with the exhaust gas. The abnormality diagnostic device includes state sensors (ph sensors 22e, 32e) for detecting an absorbing liquid state. It is determined based on the detection values from the state sensors whether or not emission control functions by the exhaust emission control devices 20, 30 are abnormal. For example, when the amount of NOx absorbed in the absorbing liquid calculated based on the detection values from the state sensors is remarkably small with respect to NOx emissions discharged from a combustion chamber per predetermined time, it is determined that the emission control functions by the exhaust emission control devices are abnormal.

Abstract: PROBLEM TO BE SOLVED: To provide a device and a production method where the raw material disposed of upon exchanging or washing is reduced, the precision in the atomization shape and atomization quantity of the raw material atomized from an atomization port is increased, the ratio at which the raw material is effectively used is increased, and there is no need of exhausting the film deposition raw material in a reaction chamber every film deposition.
SOLUTION: (1) Since a raw material atomization head 8 adopts a structure where a stop valve 12 is arranged at a position directly before an atomization port 11, the quantity of the raw material to be disposed of upon exchanging or washing can be reduced. (2) Since the raw material retaining between the stop valve 12 and the atomization port 11 is made hardly present, the precision in the atomization shape and atomization quantity can be increased. (3) Since the liquid raw material is almost uniformly atomized toward the film deposition range in a film deposition base 1 by a perforated plate 42, among the raw material atomized from atomization pores into a reaction chamber 2, the ratio of the raw material to be effectively used increases. (4) Since the liquid raw material is almost directly atomized and fed to the film deposition base 1 by the perforated plate 42, there is no need of exhausting the vaporized raw material at the inside of the reaction chamber 2 every film deposition.
