摘要:
A tightening head (1) is provided with at least two sockets (4i, 4ii) which are alternatively connected to an output shaft of a nut runner (3), a socket replacing mechanism (6) and a bolt supplying mechanism (7). The socket replacing mechanism (6) is provided with a moving mechanism (61) and a posture changing mechanism (64). The moving mechanism (61) moves each socket (4i, 4ii) between a using position where the socket (4i, 4ii) agrees with an axis of the output shaft of the nut runner (3) and a waiting position which is distant from the axis. The posture changing mechanism (64) changes a posture of each socket (4i, 4ii) to an upward posture corresponding to the waiting position and to a tightening posture corresponding to the using position. The bolt supplying mechanism 7 is provided with bolt magazines (8i, 8ii) and bolt holding mechanism (9i, 9ii). During a bolt tightening step is executed by one socket in the using position, the bolt (B) is supplied to the other socket in the waiting position.

The object of the present invention is to provide a novel compound which has various biological activities and is useful for medical and animal drugs. The present invention provides a compound represented by the formula: ##STR1## wherein R.sup.1 is COOR.sup.4, CONR.sup.5 R.sup.6, CO--R.sup.7 --OR or CH.sub.2 OR.sup.8 ; R.sup.2 is hydrogen atom, alkyl, aralkyl, heteroaryl, heteroarylalkyl, COR.sup.13, COOR.sup.14, CONR.sup.15 R.sup.16 ; R.sup.3 is hydrogen atom or OR.sup.3 ; a broken line ( - - - ) represents the presence of a double bond when R.sup.3 is oxygen atom and the absence of a double bond when R.sup.3 is OR.sup.3, or a salt or metal chelete thereof.
摘要:
The invention provides a runoff water purification system for removing pollutants which accumulate on road surfaces, thereby reducing the workload of the sewage water treatment plants and preventing environmental water pollution. The system 1 is installed under the ground of the side of the road 2. Runoff water runs into the system 1 through a curb inlet 120, is purified and discharged to a sewage pipe 56. The system is made up of a concrete box 11, in which a wall 10 separates the box into a maintenance tank 7 and a treatment tank 9, both of which are connected to each other at their lowest ends. Runoff water flows into the maintenance tank 7 and to the treatment tank 9, through the connecting conduit where pollutants are removed, and discharged to the sewage pipe.
摘要:
The diametrically larger end of a boot abutted on the open end of a joint unit on a vertical posture driving shaft is separated from the open end and held there while a liquid such as a grease is injected through the opening thus created. The end of the boot is then fitted over the outer periphery of said open end. A boot opening/closing device for doing so includes a vertically movable clamping member for clamping the boot at a portion adjacent the larger end, moving it away from the open end, holding it there during injection of the liquid by a movable nozzle and fitting it.
