The member support (30) of a friction stir spot welding device has: a backing piece (31) having a bearing surface (33) that contacts a member (10) being welded; and a supporting body (35) that supports the backing piece (31) such that the backing piece tilts in a slaved tracking manner in response to the tilting of the member (10) being welded, which is in contact with the bearing surface. With the backing piece (31), the amount of change (´) in the position of the bearing surface on the line extension of the central axis of rotation, when the bearing surface is in the reference state perpendicular to the central axis of rotation (Ac) of a rotary tool (20) and when the bearing surface tilts in a slaved tracking manner in response to the tilting of the member being welded, is equal to or less than a predetermined dimension (ds) with which the shoulder part (25) of the rotary tool is embed-ded with respect to the part being welded.
摘要:
The present invention comprises a filtration membrane device (13) which uses a filter (12) to collect solid contents (11) remaining in a branched lean solution (1005B-1). With respect to the filtration membrane device (13) when the filter (12) has been used to collect the solid contents (11): the filter (12) is cleaned using a low-concentration CO 2 absorption liquid as cleaning water (containing the absorption liquid) (16A), said low-concentration CO 2 absorption liquid circulating within a system; rough cleaning, which returns the low-concentration CO 2 absorption liquid used for cleaning to a lean solution supply line (L 13 ), is performed; the filter (12) is finish-cleaned by cleaning water (21) which does not include the CO 2 absorption liquid and which is from outside the system; the CO 2 absorption liquid which is adhered to the solid contents (11) is washed and removed; finish-cleaning water (21a) which includes the CO 2 absorption liquid is returned to the lean solution supply line (L 13 ); the moisture content within the system is maintained at a prescribed value by adjusting the water balance in an absorption tower (1004); and the concentration of the CO 2 absorption liquid which circulates within the system is kept at a prescribed concentration.

The purpose is to provide an analysis system and a management system, an analysis method, and an analysis program which enable accurate analysis of a sample containing soluble iron. An analysis system (40) comprises: a collection unit (41) that collects soluble iron contained in a sample; a reaction unit (44) that produces a reaction solution; a detection unit (45) that detects the absorbance of the reaction solution; and a control device (50) that supplies the soluble iron collected in the collection unit (41) and a reagent to the reaction unit (44).
摘要:
This exhaust gas processing equipment is provided with an exhaust line through which exhaust gas discharged from a boiler circulates, a carbon dioxide recovering device for recovering carbon dioxide included in the exhaust gas, and an exhaust gas heating device provided downstream of the carbon dioxide recovering device to heat the exhaust gas. The carbon dioxide recovering device includes a first medium line through which a first medium circulates, and a second medium line through which a second medium higher in temperature than the first medium circulates. The exhaust gas heating device includes a first heating unit for heating the exhaust gas by means of heat exchange with the first medium, and a second heating unit for heating the exhaust gas passing through the first heating unit even more by heat exchange with the second medium.
