摘要： PROBLEM TO BE SOLVED: To inexpensively, surely, rapidly and efficiently execute a defoaming by introducing cavitation air bubbles into a cleaning tank for cleaning steel strip adhering fats and oils on its surface and a circulating tank for circulating and preparing a cleaning liquid and making the air bubbles adsorbed into foams. generated in the respective tanks, thereby braking the foams SOLUTION: The steel strip 1 adhering fats and oils on its surface in a rolling stage is passed through the cleaning tank 2 via a deflector roll 14 and a sink roll 15 and is subjected to degreasing and cleaning with an alkaline cleaning liquid, such as sodium hydroxide. Further, the cleaning liquid is made to flow over form the cleaning tank 2 and is subjected to regulation of the concn., temp., etc., of the cleaning liquid in the circulating tank 4, following which the liquid is circulated via circulation piping 6 to the alkaline cleaning tank 2 by a supply pump 5. Foams 8 are excessively generated by air inclusion at the time of the circulation of the cleaning liquid and the advance of the steel strip 1 in this steel strip cleaning apparatus. The cavitation air bubbles 9 are generated by a generator 10 and are introduced into the cleaning tank 2 and the circulating tank 4. The cavitation air bubbles 9 float in the tanks and are adsorbed onto the foams 8, thereby, the foams are broken and eliminated.

摘要： PURPOSE: To ensure the prevention of coming-out of a sleeve having various outer diameters and thicknesses by arranging a flange at the fitting hole side of the sleeve fitted to a drum shaft of a coil. CONSTITUTION: A stopper 30 is fitted to a lifting loading table 29 in the state of opening a flange detaining mechanism 12 and also, the sleeve 13 is fitted to the drum shaft 11 after adjusting the height of the lifting loading table 29 while loading the sleeve 13. Successively, a steel strip is wound on the drum shaft 11 and also, after suitably expanding the diameter of the drum shaft 11, the steel strip is formed to the coil state. At the time of completing the coiling of the steel strip, the flange detaining mechanism 12 is actuated and the lifting loading table 29 is advanced in the state of detaining the flange 23 and arranged below the steel strip coil 15 and the height is adjusted to the suitable position. Then, the diameter of the drum shaft 11 is contracted, and while rotating, at need, the drum shaft 11 at low speed, a carriage 28 mounted with the lifting loading table 29 is retracted. In this case, the steel strip coil 15 is taken off leaving the sleeve 13 on the drum shaft 11 as it is.

摘要： PURPOSE:To shorten the line stop time by pinching and connecting a power feed side fixed bus bar feeding electricity to an electrode plate and a plating cell side electrode plate bus bar from both sides with a hinge-like quick joint. CONSTITUTION:A plating cell side electrode plate bus bar 2 is suspended together with a plating cell at the terminal section of an electrode feed fixed bus bar 1 erected from below, and the bus bars 1, 2 are alternately coupled. A quick joint 5 is mounted on a quick joint mount 6 installed on the bus bar 1 in the electrically insulated state, and it has three hinge bus bar pinching mobile arms 7. When the arms 7 are closed and three fixing bolts 8 fitted on opposite side to the arms 7 are fastened and fixed to arm tip bolt holes, the bus bars 1, 2 are thoroughly pinched by the joint 5, and the connection of the bus bars 1, 2 is completed. The work is completed by only three bolts, and the work load and working time can be reduced.

摘要： PURPOSE:To provide such a diaphragm valve which a fluid will not leak from an interval between a sleeve and a bonnet being engaged with a spindle even if a diaphragm is damaged. CONSTITUTION:A compressor 6 clamped to the lower part of a spindle being vertically moved is locked to a spindle 8 in a noncontact state by dint of a joint 11, installing a guide cylinder 12, slidingly engaging with this joint 11, in a spot in and around a spindle supporting hole 5a in a bonnet 5, and a seal ring 14 is fitted in an inner circumferential surface of the guide cylinder 12, thus an interval between the guide cylinder 12 and the joint 11 is made so as to be sealed up at all times. With this constitution, even if a diaphragm 10 is broken down and a fluid flows into a storage chamber of the compressor 6, this fluid will in no case leak to the outside of the bonnet 5 from a sleeve 7 supporting the spindle 8.

摘要： PURPOSE:To safely and surely carry out scrap disposal at a lower instalation cost with a simple maintenance procedure, by opening and closing the bottom of a bucket carrier veheicle recirpocating between a scrap storing position and a scrap discharging position so that the store scrap may be discharged without the carrier vehicle being entirely overturned. CONSTITUTION:Auxiliary wheels 9 are attached to the bottom plate 10 of a bucket carrier vehicle 1 inside of main wheels 8 provided at both ends of the carrier vehicle 1. When the bucket carrier vehicle 8 comes to a predetermined position above a pit 4, the auxiliary wheels 9 are positioned on movable rails 3a which are turned and lowered by means of a bottom plate opening and closing device A while the main wheels 8 are positioned on stationary rails 3. The bottom plate opening and closing device A turns and lowers the movable rails 3a in association with the extending and retracting motions of an actuator 12a so that the bottom plate 10 are inclined together with the movable rails 3a to open the bottom section of the vehicle. Accordingly, scrap is discharged through a chute 5 into a main bucket 6.
