Abstract: This machine tool is provided with: a bridge which is provided on a base in such a way as to straddle a moving body in a direction (X) perpendicular to a direction of movement (Z) of the moving body at a stroke end (E2) of the moving body; a pallet exchanging arm which is provided above the bridge and which engages with a pallet (P) supported on the moving body and a pallet (P) on a pallet loading station, lifts both pallets (P), and pivots about a vertical axis (Ov) to exchange the two pallets (P); and an arm drive device which is provided projecting upward on the bridge, and which moves the pallet exchanging arm along the vertical axis (Ov) and causes the pallet exchanging arm to pivot about the vertical axis (Ov).

Abstract: A machine tool having at least two rotary feed axes (B, C) is provided with: a base; a column which moves in a left-right direction (X); a main spindle head which moves in a vertical direction (Y); and a table which has a workpiece attachment surface and in which the workpiece attachment surface is oriented in a plurality of attitudes including a horizontal attitude and a vertical attitude. The column is guided in the left-right direction (X) by means of an inclined linear motion guide which faces forward and upward. The table includes: a first table stand having an inclined rotary guide which faces backward and upward; and a second table stand which is rotationally fed about an inclined axis (Oc) perpendicular to the inclined rotary guide. The inclined linear motion guide of the column and the inclined rotary guide of the table are disposed facing one another.

Abstract: Sodium N-acetylneuraminate trihydrate herein provided is represented by the following formula: ##STR1## The sodium N-acetylneuraminate trihydrate can be prepared, for instance, according to a method which comprises the steps of: dissolving sodium N-acetylneuraminate in water or in a mixture of water and an organic solvent; allowing the resulting solution to stand; precipitating and separating the resulting crystals of sodium N-acetylneuraminate.trihydrate; and then drying the separated crystals. The sodium N-acetylneuraminate trihydrate has very low hygroscopicity and hence can be handled without any difficulty in the form of powder.
