Abstract: A pulley assembly having first and second members. The first member is capable of cooperating with a power transmission belt to drive/be driven by the belt. The first member is movable guidingly relative to the second member around a first axis. A coil spring has a length and a circumference and a first portion attached to the first member and a second portion attached to the second member so that a force tending to move the first/second member around the first axis is transmitted through the coil spring to the second/first member. At least one of the first and second members has a groove bounded by a surface into which the respective portion of the coil spring is fit. The respective portion of the coil spring is clamp fit within the groove.

Abstract: An optimal portfolio determining method enables high speed determination of objective financial product which optimize availability for institutional buyer or retail investor and purchasing amount on the basis of information relating to earning rate or the like of individual name and information relating to information factors influencing for earning rate, and a system for realizing the method.

Abstract: This enterprise portfolio simulation system includes the mechanisms of selecting companies having a large mutual influence from a company's own project portfolio, a business partner company, other competing companies, and still other companies giving an influence on the company's own project portfolio, the business partner company, and the other competing companies; configuring a company network with the own company, the business partner company, and the other competing companies; making each of the own company, the business partner company, and the other competing companies perform a reasonable intention decision while mutually giving an influence; and performing a numerical experiment of an economic activity.

Abstract: The system comprises a risk allocation elation display unit that displays the relations between risk allocations of formers and latters, dependent on the decision of the formers and the decision of the latters, and the returns in a multi-dimensional format; and a risk allocation relation selection unit that accepts a user selection entry for one or more relations. The system further comprises an asset value simulation unit allowing a user to enter a management plan change rule, based on a difference between the risk allocation relations and actual relations, for a management plan satisfying the risk allocation relation selected by the user through the risk allocation relation selection unit and that presents an asset value transition that would result when management is done based on the management plan change rule.

Abstract: An object of the present invention is to provide an engine exhaust gas cleaning system which can accurately judge whether or not there is the remaining capacity in an NOx trapping amount of an NOx trapping agent, can optimize the timing of NOx purge control, and can diagnose the deterioration of the NOx trapping agent.

Abstract: The present invention has its object to judge the establishment of conditions influencing on the evaluation of performance of a NOx catalyst, whereby when being established, the evaluation of performance of the NOx catalyst is stopped to thereby prevent the performance of the NOx catalyst from being erroneously judged.

Abstract: An exhaust gas cleaning system for an engine capable of judging the amount of trapped NOx and the oxygen storage capacity of an NOx trap agent and which can diagnose the deterioration of the NOx trap agent. The NOx trap is arranged in an exhaust gas passage and the air-fuel ratio of the exhaust gas is temporally changed from a lean air-fuel ratio to the stoichiometric air-fuel ratio or a rich air-fuel ratio with a predetermined cycle. The NOx trapping occurs by absorbing or adsorbing NOx in the exhaust gas when an air-fuel ratio of the exhaust gas is a lean air-fuel ratio and by releasing or reducing NOx when the air-fuel ratio is a rich air-fuel ratio. The amount of trapped NOx is judged from the oxygen concentration and the oxygen concentration in the exhaust gas is detected in the exhaust gas passage in the downstream side of the NOx trap and determined by taking the oxygen storage capacity when the air-fuel ratio of the exhaust gas changes to the stoichiometric air-fuel ratio or the rich air-fuel ratio.

Abstract: The invention provides a method of controlling an air-fuel ratio and for diagnosing a deterioration of a catalyst having an NOx trapping agent in an internal combustion engine. An exhaust gas purifying apparatus having an NOx trapping agent arranged within an exhaust gas passage, an air-fuel ratio changing means temporarily changing the air-fuel ratio of the exhaust gas from the lean to the stoichiometric or rich air-fuel ratio at a predetermined cycle, a particular component detecting means detecting a particular component in the exhaust gas downstream the NOx trapping agent, a NOx discharge or reduction completion judging means, and NOx discharge or reduction completion time detecting means detecting a time required for purifying the NOx.

Abstract: Two resin members are provided, at surfaces to be joined, with side surfaces, respectively. The side surfaces and the side surfaces are substantially parallel with respect to an opposing direction of the resin members. After the side surfaces are heated and fused by infrared heaters movably arranged in the vicinity of the respective side surfaces, the side surfaces are joined together under pressure.
