Filed: 2002-04-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device, and a purifying method in the exhaust emission control device capable of sufficiently purifying an entire NOx occluding agent.  <P>SOLUTION: This exhaust emission control device having an NOx occluding agent 12 comprises flow rate control means 24, 26 for controlling an exhaust flow rate distributed in the occluding agent when the occluding agent 12 must be purified by adjusting a proportion of a flow rate of a first path 16, where the exhaust gas passes through the occluding agent, and a flow rate of a second path 18 bypassing the occluding agent; and a reducing agent adding means 32 upstream of the occluding agent. In this exhaust emission control device 20, the flow rate control means 24, 26 are adjusted according to the occluding agent temperature in a manner that the exhaust flow rate distributed in the occluding agent becomes a target flow rate regardless of a total exhaust gas volume from an engine. Because the reducing agent flows across the entire occluding agent, the entire temperature can be increased without temperature difference comparatively, so as to efficiently purify the entire occluding agent.  <P>COPYRIGHT: (C)2004,JPO

Title: Light emitting element and display device applying the same
Inventor: CHOI BYOUNG-IYONG
IPC: G09F9/40
Filed: 2002-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element that is excellent in luminous efficiency and to provide a display device applying the element. SOLUTION: The light emitting element includes an n- or p-type substrate, at least one doped region which is doped in the type opposite to that of the substrate with a prescribed dopant so that light emission may occur due to a quantum constraining effect in the p-n junction between the doped region and substrate on at least one surface of the substrate, and electrodes which cause the light emitted from the p-n junction of the doped region to be emitted through both surfaces of the substrate. Consequently, the luminous efficiency of the light emitting element becomes superior than those of light emitting elements using porous silicon and nano-crystalline silicon. In addition, since the light emitted from the p-n junction is made to be emitted from both sides of the substrate and the whole light emitted in both directions can be utilized, the luminous efficiency can be maximized.
