摘要： PROBLEM TO BE SOLVED: To provide a system which can precisely control the nitrogen energy during a plasma nitriding operation. SOLUTION: This control method in a plasma nitriding technique comprises the steps of: employing a signal which indicates an excited state of plasma during the plasma nitriding operation, as a measurement object; and controlling a plasma power source by feeding the measurement result back to the source. The control process includes: detecting a light from an aperture 5b of the side of a main body 5 of a furnace through a condensing lens system 3 during the plasma nitriding operation to determine the excited state of the plasma; guiding the detected light to an emission spectroscopy photometer 4 through an optical fiber 19; condensing the detected light with a condensing unit 19a; obtaining the spectrum of the light through a monochromator 17; detecting the spectrum with an ICCD detecting device 18 provided with a gate; and informing the intensity of the emission spectrum to a controller 20 through a signal line 21. The controller 20 has an interface 23 and a personal computer 22. The personal computer 22 calculates the intensity of the emission spectrum, compares the intensity with the preset intensity which has been set in an operating panel 25, and outputs the control signal corresponding to the difference between the intensities, to the plasma power source 8.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning catalyst which can maximize slit effects. SOLUTION: The exhaust gas cleaning catalyst is formed by coating a carrier having slits with a catalytic component, in which the GSA (geometric surface area) of the front potion of the carrier is reduced by 10-25% with respect to the GSA of a carrier without slit. Also, the GSA of the central part of the carrier is reduced by 10-30% with respect to the GSA of the carrier without slit. The exhaust gas cleaning catalyst is formed by coating the carrier having slits and the diameter of the slits is made smaller from the central part of the carrier toward the outer peripheral part of the carrier. The number of the slits is reduced from the front part of the carrier toward the rear part of the carrier. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a transition metal nitride containing a low oxygen content and a high nitrogen content. SOLUTION: A base material comprising a stainless steel is subjected to gas nitriding to form a transition metal nitride on a surface layer part of the base material. A transition metal nitride layer containing the high oxygen content formed by the gas nitriding is removed by applying surface treatment to the surface part of the surface layer using a phosphoric acid-based solution or a solution containing a phosphoric acid and a fluoride-based solution. Thus, the transition metal nitride layer containing the low oxygen content and high nitrogen content is left behind on the surface of the base material. Since the transition metal nitride contains the low oxygen content and high nitrogen content, it has excellent conductivity. COPYRIGHT: (C)2008,JPO&INPIT
