Abstract: The present invention provides a catalyst composition which can decompose an organic nitrogen compound at a relatively low temperature to convert the compound to N2 and render it harmless in the purification of an exhaust gas containing the compound (nitrogen-based exhaust gas); a catalyst containing the catalyst composition; a method for producing the catalyst; and an exhaust gas purification apparatus containing the catalyst. By using a catalyst composition formed by mixing copper oxide particles and zeolite particles, an organic nitrogen compound and/or ammonia can be converted to N2 highly selectively. The catalyst composition of the present invention may further contain a manganese oxide and/or a precious metal.

Each component includes outer circumference terminals arranged along an outer circumference, inner circumference terminals arranged along an inner circumference, and connection portions connecting corresponding outer and inner circumference terminals that are separated from each other by a predetermined angle in a circumferential direction.

Abstract: A commutator has a tabular holding portion defining a thickness direction. A plurality of segments are arranged in one end in the thickness direction of the holding portion in a radial pattern. Each of the segments has a slidable contact surface which is perpendicular to the thickness direction. A feeding brush is brought into slidable contact with the slidable contact surface. A tabular short-circuit unit short-circuits the segments to be set to the same electric potential with each other. The short-circuit unit is arranged parallel to the slidable contact surface. Accordingly, it is possible to enlarge a cross-sectional area which is perpendicular to a current passing direction of the coupling portion while suppressing an enlargement of a dimension in the axial direction of the commutator.

Abstract: The challenge for the present invention is to provide a catalyst composition restrained from declining in performance over time in purifying an exhaust gas containing an organic compound a silicon compound, a catalyst containing the catalyst composition, and a method for producing the catalyst. This challenge is solved by using a catalyst composition containing zeolite added to precious metal-carried alumina, and the silicon resistance of the catalyst is improved greatly. The amount of acid of the zeolite added is preferably in the range of 0.4 mmol·NH3/g to 1.5 mmol·NH3/g.

Each short-circuit conductor is connected, either directly or via corresponding one of the segments, to the surge absorbing element, so that the surge absorbing element is electrically interposed between the ends of each armature coil.

This increases the constraint torque/mass ratio of the direct current motor.
