PURPOSE:NOx in exhaust gases of relatively high temperatures is catalytically reduced by NH3 by the use of special catalyst carriers.

Process for reductive removal of nitrogen oxides

PROBLEM TO BE SOLVED: To provide a connector to transmit electric power, by which electrical connection is safely performed even at such a place as moisture exists, a connection failure of a contact terminal is reduced, and furthermore, fitting and removal are easily performed with one hand. SOLUTION: In the noncontact power transmission connector, one or more power transmission portions A 7, power transmission portions B 8, and power transmission portions C are combined and used for a primary coil, a secondary coil, a tertiary coil or more. They are penetrated each other in parallel or in series through a ring-like penetration portion of the power transmission portion A, the power transmission portion B, or the power transmission portion C to transmit the power. In the power transmission portion A, an electric wire 1 is wound around a ring-like magnetic substance 3 adhesively on average, coating is applied for relaxation of an impact and waterproofing, and the power transmission portion is formed into a clamp which can be easily opened and closed with one hand by sliding, pushing or pulling one portion. In the power transmission portion B, the electric wire is wound in the shape of a ring, without using the magnetic substance, and the portion is completely sealed by a non-conductive and non-magnetic case. In the power transmission portion C, only the coated ring-like magnetic substance is used. COPYRIGHT: (C)2008,JPO&INPIT

Noncontact power transmission connector

PURPOSE:To provide the reflection type optical sensor which decreases crosstalks of light between light emitting elements and a light receiving element. CONSTITUTION:This optical sensor is mounted by shifting the distances from the light emitting elements 1 and the light receiving element 2 to a light transparent body 3. The light emitted from the light emitting elements 1 cannot directly enter the light receiving element 2 or is prevented from directly entering this element by being reflected by the incident surface 3a of the light transparent body 3. The light which is reflected by the body A to be detected and is emitted from the light transparent body 3 is surely made incident on the light receiving element 2 and, therefore, the generation of the crosstalk between the light emitting elements 1 and the light receiving element 2 is obviated and the taking out of the intermediate value of the output is easy.

PURPOSE:In a method of catalytic reduction, using NH3, of the NOx in the exhaust gas containing SOx from various stationary gas generating sources, catalysts which remove the NOx for a long period of time at high efficiency without being subjected to the deterioration in their activity occurring in the SOx are used.
