Abstract: Disclosed is a thioquinolone derivative which exhibits highly selective antibacterial activity against Helicobacter pylori.

Abstract: A slitter scorer including a pair of rotating shafts and roll heads fixedly mounted opposite to each other on said rotating shafts, thereby working a sheet carried between said roll heads, comprises plurality of pairs of head holding shafts having the same diameter as that of said pair of rotating shafts and capable of being disposed on an extension of an end of said pair of rotating shafts concentrically to said pair of rotating shafts, head exchanging means for exchanging said plurality of pairs of head holding shafts, roll heads held to said head holding shafts and means for moving said roll heads axially, whereby said roll heads on the rotating shafts and said roll heads on said head holding shafts are exchanged by slidably moving said rotating shafts and said head holding shafts.

Abstract: An apparatus for determining positions of a plurality of heads in accordance with the present invention is employable for a slitter scorer on a corrugate machine for cutting or scoring a sheet of paper board. The apparatus of the invention is so constructed that each of heads slidably disposed on a shaft is located at a voluntary position on the shaft by repeating the operational steps of displacing the heads as a group of at least more than two heads by pushing them from the rear side with the use of substantially single shifter adapted to move in parallel with the shaft and parting away from the shifter one head at the rearmost end among the moving heads when the shifter reaches a predetermined position, wherein the apparatus is provided with means for limiting forward displacing of a head at the foremost end among the heads which are displaced by means of the shifter.

Abstract: A rotary plate-shape material cutting apparatus is disclosed. The apparatus comprises a pair of hollow knife cylinders, each provided with a knife on the circumferential surface and adapted to rotate in mutually opposite directions, shafts piercing the hollow portion of the knife cylinders and having both ends thereof supported by frames, bearings positioned at both ends of the knife cylinders and interposed between the shafts and knife cylinders and at least one roll provided at each of the knife cylinders, rotatably supported therein and having its rotary surface kept in contact with the external circumference of the shafts.

Abstract: A method and apparatus for minimizing or eliminating warp in corrugated board by imparting different curvature on alternate successive lengths of the board being manufactured prior to its being stacked. The corrugated board, as it moves through the manufacturing apparatus, is subjected to treatment on its upper surfaces at different intervals that the lower surfaces to impart various curvatures to the sections being cut and stacked. As the cut corrugated board sections are accumulated in the stack alternate groups of board sections have opposite curvature throughout the height of the stack. The stacked sections are maintained in this disposition a time sufficient for the weight of the stack to render the formed sheets substantially flat.
