It would be preferable for the film to have: a spin density of 1×1018-1×1021 spins/cm3; a carbon concentration of at least 99.5 atomic percentage; a hydrogen concentration of no more than 0.5 atomic percentage; an inert gas element concentration of no more than 0.5 atomic percentage; and a Knoop hardness of 3000-7000. A mixed layer with a thickness of at least 0.5 nm and no more than 10 nm is formed from a parent material and at least material selected from: B, Al, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and W. An amorphous carbon film is disposed on the mixed layer or a metallic intermediate layer formed on the mixed layer, thereby increasing adhesion.

摘要： Amorphous carbon coated tools include substrates formed from a cubic boron nitride sintered body, a diamond sintered body, a silicon nitride sintered body, or an aluminum oxide-titanium carbide sintered body, and amorphous carbon films thereon to make the cutting edges of the tools. The amorphous carbon films contain hydrogen at 5 atomic percent or below and have a maximum thickness of 0.05 μm to 0.5 μm on the cutting edges. The amorphous carbon films are most suitable for applications to cutting tools exemplified by cutters, knives, and slitters, and to indexable inserts used for example in turning tools including drills, endmills, and reamers, and milling cutters.

摘要： An amorphous carbon coated tool includes a base material of WC base cemented carbide, and an amorphous carbon film formed on this base material. The cobalt content in the base material is at least 12% by mass. The maximum thickness of the amorphous carbon film is at least 0.05 μm and not more than 0.5 μm at the cutting edge. The amorphous carbon film is deposited with graphite as the source material by physical vapor deposition in an atmosphere substantially absent of hydrogen. The amorphous carbon film coated tool superior in wear resistance and adhesion resistance is preferably applicable to rotating tools such as drills, end mills and reamers, indexable inserts used for milling cutters and turning tools, and cutting-off tools such as cutters, knives, or slitters.

摘要： The electromagnetic vibration suppression device includes a plurality of electromagnet pairs arranged in the width direction of a steel plate and which suppresses vibration of the steel plate running between electromagnets in each electromagnet pair using a control unit. The pseudo displacement calculation means calculates a pseudo displacement amount for the steel plate on the basis of the switching between ON and OFF of a sensor attached to the electromagnet pairs. The pseudo edge position calculation means calculates a pseudo edge position for the steel plate on the basis of the pseudo displacement amount. The current amount control means individually controls the amount of current that flows to the electromagnets on the basis of the pseudo edge position.
