Abstract: A method of treating a gaseous stream containing one or more volatile nitrogen containing organic compounds which comprises contacting the gaseous stream and an oxidizing agent with a catalyst at relatively low temperatures to cause oxidation of the volatile nitrogen-containing organic compounds. The catalyst employed promotes the oxidation reaction to selectively produce N.sub.2 O, N.sub.2, CO.sub.2 and H.sub.2 O without generating significant amounts of NO.sub.x to permit the reaction products to be vented directly into the atmosphere. The catalyst includes a selected amount of a noble or base metal deposited on a catalyst support comprising titania and zirconia. One or more of the elements molybdenum, tungsten or vanadium are added as promoters to the composition which minimizes the generation of NO.sub.x among the reaction products. Lanthanum may be added to provide better thermal stability and increase the selectivity for producing N.sub.2 among the reaction products.

Abstract: Plant operating conditions 1, apparatus operating conditions 2 and environment conditions 3 are accumulated, combined and put together as a set of plant status variables 8 through a monitor 6, while water chemistry information 4 is accumulated as another set of plant status variables 9. The set of status variables 8 is updated and the past data are accumulated in the set of status variables 9. Periodical inspection data 5 are also accumulated in the set of status variables 9 along with the water chemistry information 4. The set 9 is compressed and stored as a plant chart 11 such as a personal clinical chart. A status variable prediction 12 is performed in consideration of the personality of a plant. Both data of the sets 8 and 10 are compared with each other by comparison means 13. If both the data nearly coincide with each other, the plant is diagnosed to the normal and, if not, it is diagnosed to be abnormal.

Abstract: Concerning a tilt detecting optical pickup in an optical disk playback device, a highly precise tilt error signal can be obtained by a simple structure. As a structure for achieving this, there are provided a diffraction grating, on which a grating groove pattern has been engraved, capable of adding coma aberration components to + and - primary diffracted light on an optical path between a laser diode, which becomes a playback light source, and an optical disk, and a light-receiving element capable of receiving the diffracted light. The output from a signal processing circuit capable of calculating a difference between each light receiving strength becomes a tilt error signal. By deforming the aforesaid grating groove pattern, the layout of the coma aberration components can be changed. Also, a tilt error signal can be obtained from a difference in bit error numbers in playback signals from diffracted light having coma aberration.
