Abstract: There is provided an exhaust gas purification system that allows efficient purification of NOx present in exhaust gas emitted from an internal combustion engine. The exhaust gas purification system of the disclosure comprises a first exhaust gas purification device that purifies exhaust gas emitted from an internal combustion engine, wherein the atmosphere alternately switches between a reducing agent-excess atmosphere and an oxidizing agent-excess atmosphere with respect to the stoichiometric atmosphere, and a second exhaust gas purification device that further purifies the exhaust gas that has been purified by the first exhaust gas purification device, wherein the first exhaust gas purification device has a three-way catalyst, and the second exhaust gas purification device has an exhaust gas purifying catalyst that comprises an AMn2O4 spinel-type oxide support (A=Mg, Zn or Li) on which a precious metal is supported.

Abstract: A vehicle control apparatus comprising a navigation system and a control unit, wherein the navigation system includes a map database, a position acquisition unit, a route determination unit, and an output unit configured to output road information on a plurality of locations from a position of the vehicle to a location at a predetermined distance ahead on the target route, wherein the control unit includes a buffer unit configured to store the road information as the road information on a first distance interval, and a controller unit configured to control the speed of the vehicle, wherein the output unit is configured to, in response to changing the target route, thin out the road information such that the number of data becomes less than that of the road information on the first distance interval, and wherein the buffer unit is configured to store the thinned-out road information.

Abstract: In a coil forming device, an edge line in an escape region is formed so that a clearance between the edge line in the escape region and a recess portion in an axis direction is larger than a minimum clearance between the edge line in an inclined region and the recess portion in the axis direction. When a second die is rotated relative to a first die in the clockwise direction the flat-square conductive material end is bent in flatwise bending by the recess portion and the inclined region of a protrusion portion, and then, the flat-square conductive material end reaches the escape region.
