Abstract: <P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device which decreases temperature differences between respective sections in raising the temperature of NOx occlusion agent 12, thus keeping the temperature of the entire occlusion agent not less than sulfur emission temperature.  <P>SOLUTION: A reducing agent is added with the flow rate of exhaust gas flowing through the NOx occlusion agent 12 taken as a predetermined flow rate so that the temperature of the entire NOx occlusion agent 12 is not less than the sulfur emission temperature in discharging the sulfur content from the NOx occlusion agent 12. The device 20 decreases a temperature difference between the temperatures on the upstream and downstream sides of the NOx occlusion agent 12 by increasing the flow rate to exhaust gas up to a predetermined another flow rate in such a state where the flow rate of the exhaust gas flowing through the NOx occlusion agent 12 is made to flow unidirectionally without reversal of the passing flow. As a result, the difference in the temperatures on the upstream and downstream sides of the NOx occlusion agent 12 decreases, and the entire NOx occlusion agent 12 can be kept not less than the sulfur emission temperature at the same time, thus attaining sufficient regeneration of sulfur poisoning over the NOx occlusion agent 12.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide an advance registration type electronic settlement system and an advance registration type electronic settlement program capable of improving the processing speed of payment processing.  <P>SOLUTION: When a registration terminal 41 registers a user, authentication due to a public key cryptosystem is executed to the public key certificate of an IC card 3 acquired from the IC card 3. When the authentication is normal, the registration terminal 41 gives a membership number and a card individual key for store which are effective for a prescribed period to the user, and memorizes them on the IC card 3. When the user desires to pay using the IC card 3, a payment terminal 42 informs payment information showing the contents of the payment and a random number for authentication to the IC card 3 and requires the payment. The IC card 3 outputs a payment certificate in which the payment information is encrypted by a private key of the IC card 3 and the card authentication data in which the random number for authentication is encrypted by a card individual key for the store to the payment terminal 42. When the payment terminal 42 obtains the random number for the authentication by verifying the card authentication data by using the card individual key for the store, the payment terminal 42 accepts the payment certificate.  <P>COPYRIGHT: (C)2004,JPO

IPC: B65H5/02
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To suppress the skewing of a belt more effectively than in the past by shortening the time required from the generation of skewing of the belt to the correction of the screwing.  <P>SOLUTION: The lateral positions L1 and L2 of an intermediate transfer belt 10 are detected in a contact start position P1 where the belt is wound on a steering roller 14 for stretching it and starts to contact and a separation start position P2 where the belt starts to separate. The difference ΔL between these detection results is calculated. Since the difference ΔL shows the cause of the skewing of the belt, the cause of the generation is directly fed back to the steering operation. Accordingly, a time lag or overshoot generated in a conventional steering method is hardly caused, and a stable belt drive can be realized without causing the large skewing of the belt.  <P>COPYRIGHT: (C)2004,JPO
