Abstract: A Cr trapping agent is disposed so that it contacts with constituting components of the substrate containing Cr. As the Cr trapping agent, an element or Ag is used, wherein the element is stronger in basicity than alkali metals or alkaline earth metals. Since the Cr trapping agent prevents transfer of Cr towards the alkali metals or alkaline earth metals, the reaction between Cr and alkali metals or alkaline earth metals is prevented.

Abstract: Use of a metallic material containing chromium as a substrate of an exhaust gas purifying catalyst has a problem that the chromium contained in the substrate migrates to a catalytically active component and reacts with the catalytically active component to reduce exhaust gas purification performance. Thus, a film which inhibits the chromium contained in the substrate from migrating is arranged on the substrate's surface. The film is desirably formed by oxidizing a substrate in the air. It is also desirable that a substrate containing aluminum therein be oxidized to cause aluminum contained in the substrate to separate out and thereby form an alpha-alumina film. The film is preferably such that, when the exhaust gas purifying catalyst is heated at 850° C. in the air for 300 hours, the amount of chromium migrated to the catalytically active component is controlled to 0.5 percent by weight or less based on the catalytically active component.

Abstract: A hazardous material detection system that can suppress occurrence of contamination due to ionization. When a sensor detects that a test sample has entered an inspection region of an X-ray inspection device as a belt conveyor moves, a corona discharge power supply in a hazardous material detection device is turned on for a constant time, to introduce a qaseous sample containing a substance stuck to the test sample into the hazardous material detection device via a sucking section and gaseous sample introduction piping, in order to ionize the gaseous sample and analyze it at an analyzer, based on a result of which analysis, a data processor decides whether the gaseous sample contains a hazardous material, to display a decision result on a screen. When the test sample is detected by an exit side sensor, the corona discharge power supply is turned off.

Abstract: Temperature data of each picture element output from a infrared camera looking at a scene to be watched is compared with the same data of a previous frame. Temperature data which has changed from the previous frame is input to a histogram operator having a region defined by the temperature change and quantity of the picture elements. When the quantity of picture elements in the defined region exceeds a threshold level, it is recognized that a certain object having considerable temperature change and size has been detected. Thus, a signal is output to trigger an alarm system, or to sustain circulating frame memories which have recorded the previous scenes so that the scenes of visible light as well as the temperatue patterns for frames before, on, and after the trigger signal can be reproduced as visual images of a display screen.
