Abstract: PURPOSE:To connect a flow passage pipe to the header pipe of a heat exchanger simply and surely by a method wherein a stopper is fitted previously into the window hole of a receiving port unit, then, an inserting unit is inserted into the receiving port unit. CONSTITUTION:A stopper 10 is fitted into the window hole 5 of a header pipe 11 previously while riding over the lattice unit 4c of a receiving port unit 4 from the outside of the same. In this case, the arced elastic leg body 7 of the stopper 10 is fitted into the window hole 5 under a condition that the leg body is projected inwardly and, at the same time, a head unit 8 pinches the lattice unit 4c. Next, the inserting unit 3 of a flow passage pipe 12 is inserted into the receiving port unit whereby the annular projection 1 of the inserting unit 3 is advanced inwardly into the receiving port unit 4 along a slanted surface 7a while opening the arced elastic leg body 7 against the elastic force thereof. Then, the arced projection 1 is abutted against the stepped part 4b of the receiving port unit 4 and, at the same time, the arced elastic leg body 7 is restored into a direction, in which the leg bodies are approached to each other by the elastic force thereof. As a result, the annular projection 1 is fixed while being pinched between the stepped part 4b and the arced leg body 7. According to the engagement of the inserting unit 3 and the receiving port unit 4, the flow passage pipe 12 is connected to the header pipe 11.

Filed: 1986-08-18
Abstract: PURPOSE:To improve the efficiency of an inference processing, by using a knowledge module in a low-order level first, shifting a processing to the processing by the knowledge module of order higher by one level when no solution is obtained, and returning the processing to a low level after obtaining the solution when it is obtained. CONSTITUTION:An interruption processing mechanism 23 selects the knowledge module 14 from the lowest order level based on an initial condition held in a working memory 22, and an inference engine 21 executes an inference processing, and when no conclusion is obtained, an interruption request is issued to the interruption processing mechanism 23. The interruption processing mechanism 23 selects the knowledge module 15, and the inference engine 21 executes the inference processing. Thus, when the inference processing is completed at a certain level, the inference engine 21 calls the interruption processing mechanism 23, and the interruption processing mechanism 23 returns the inference engine 21 to the level at time of interruption based on a bit of holding return information, and starts up the inference processing again. In this way, it is possible to generate the hierarchical constitution of the knowledge module, and to improve the efficiency of execution by expanding a rule retrieving range in order, to a high order level only when the no conclusion is obtained at the low order level.
