Abstract: PROBLEM TO BE SOLVED: To maintain the NOx purification capacity of an NOx catalyst in a state of generally high level and suppress the deterioration of fuel economy in an exhaust emission control system having the NOx catalyst for occluding and reducing NOx in the exhaust gases and recovering the NOx purification capacity of the NOx catalyst by adding fuel into exhaust gases.
SOLUTION: In this exhaust emission control system, only when a state in which the NOx catalyst cannot reduce occluded NOx by adding the fuel to the exhaust gases is moved to a state in which the NOx catalyst can reduce occluded NOx, the addition of the fuel to the exhaust gases per unit time is increased. After the state is moved to the state in which the NOx purification capacity of the NOx catalyst is increased by the concentrated addition of the fuel, the addition of the fuel into the exhaust gases per unit time is decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a bipedal walking robot in which a target trunk attitude vector commanded to a robot coincides with an actual trunk attitude vector. SOLUTION: First, shifting vector is once measured. After that, a target trunk attitude vector is corrected by "shifting vector", and a joint angle is calculated from the corrected target trunk attitude vector. When the target trunk attitude vector is corrected by " shifting vector" to control the robot, the robot changes its attitude taking the target trunk attitude vector corrected by "shifting vector" as a target vector. At that time, the robot shifts from the target trunk attitude vector corrected by "shifting vector" by "the shifting vector", so the trunk attitude of the robot coincides with the target trunk attitude vector which has not been corrected by the shifting vector. In this method, the actual trunk attitude of the robot is made to near the trunk attitude that an operator desires. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To adjust the stiffness of a lower limb of a bipedal walking robot to a suitable level. SOLUTION: This robot walks with stiffness varied following up a walking pattern. Immediately before the transition from the left foot grounding state to both feet grounding state, the stiffness of the right lower limb is lowered, and immediately before the transition from the right foot grounding state to both feet grounding state, the stiffness of the left lower limb is lowered. The stiffness of a free leg is high while it is a free leg (while it is floating in the air), and the attitude of the free leg is regulated from being largely shifted by the gravity or inertia force. Immediately before the free leg is grounded, the stiffness is lowered, so that even if there are unexpected projecting and recessed parts in the landing spot, it flexibly respond to it. When it is necessary to keep the attitude, the stiffness is heightened to keep a stable attitude, and when flexible respond is needed, flexible response is performed. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a bipedal walking robot corrected to a target ZMP track for reducing the load imposed on the robot by solving the problem wherein in the conventional target ZMP (zero moment point) track, load on the robot is high, so that the robot cannot walk at high speed. SOLUTION: A track connecting a target ZMP within the grounding surface of one foot within the grounding period of one foot and a target ZMP within the grounding surface of the other foot within the grounding period of the other foot by a track including constant acceleration track and constant deceleration track within the both feet grounding period are calculated. As a result, a target ZMP track for separating from one foot grounding surface at constant acceleration within the both feet grounding period and reaching the other foot grounding surface at constant deceleration is calculated. Holding down the acceleration and deceleration of the robot operation required for coinciding the actual ZMP with the target ZMP is realized. The operation of the robot is smoothed, so that the robot can walk at high speed. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To prevent the outflow of an exhaust gas of rich air-fuel ratio to a downstream of an exhaust emission control device without passing through a NOx catalyst. SOLUTION: This device comprises the NOx catalyst 32 for holding NOx in the exhaust gas when the air-fuel ratio of the inflow exhaust gas is lean, and reducing and clarifying the held NOx by a reducer when the air-fuel ratio of the inflow exhaust gas is enriched. The air-fuel ratio of the exhaust gas flowing into the NOx catalyst is enriched by operating an enriching means 19 under predetermined conditions. A switching means 26 is mounted to switch the inflow mode of the exhaust gas to the NOx catalyst between a forward mode and a backward mode. The switching of the inflow mode by the switching means is inhibited during the operation of the enriching means, and further the switching of the inflow mode by the switching means is forbidden for a predetermined switch forbidding period even after the stop of the operation of the enriching means.
