[Problem] The invention provides a machining tool capable of improving work production efficiency and downsizing the whole machine. [Solution] In the machining tool having a plurality of spindles 111 and a plurality of tool rests 120, the respective tool rests 120 are disposed on the side of the end surface of the spindles 111, a workpiece holding means 130 is provided at least on one of the neighboring two tool rests 120, a moving range of the tool rest 120 having the workpiece holding means 130 is set so as to include position where the both spindles 111 face to the workpiece holding means 130, a moving range of the tool rest 120 corresponding to the neighboring spindle 111 described above is set so that at least part thereof overlaps with the moving range of the tool rest 120 and so that it is slidably moved to position for avoiding the tool rests 120 from abutting from each other.

A superconducting material useful for forming electrolytic devices is made by establishing multiple niobium or tantalum components in a primary billet of a ductile material; working the primary billet through a series of reduction steps to form the niobium or tantalum components into elongated elements; cutting and restacking the resulting elongated elements with a porous confining layer to form a secondary billet, working the secondary billet through a series of reduction steps including twisting and final rolling to thin ribbon cross-sections with greater than 5:1 Aspect Ratios; cutting the resulting elongated billet into sections; and leaching the core and sheath at least in part.

The present invention relates to new tungsten carbides which are doped with fluorine in an amount of up to 0.5 wt % and which can also be doped with fluorocarbon compositions. These tungsten carbides are produced according to a new CVD method in which the phase contains tungsten hexafluoride, hydrogen and a carbon-containing gas. This method is characterised in that the carbon-containing gas is previously thermally activated. The tungsten carbide coatings can be applied onto construction material and articles made therefrom. These coatings exhibit a high wear and corrosion resistance as well as a high chemical stability.

An alloy that contains at least two metals and can be used as a substrate (901) for a superconductor (900) is disclosed. The alloy can contain an oxide former. The alloy can have biaxial or cube texture. The substrate can be used in a multilayer superconductor, which can further include one or more buffer layer (902) disposed between the substrate and the superconductor material (903). The alloys can be made by a process that involves first rolling the alloy, and then annealing the alloy. A relatively large volume percentage of the alloy can be formed of grains having a biaxial or cube structure.
