摘要： PURPOSE:To easily prepare a non-flat amorphous metal strip having a large surface area per unit length as well as having a uniform thickness and excellent in durability, by injecting a molten metal to a roll having recessed and protruded parts provided to the surface thereof to rapidly cool and solidify the same. CONSTITUTION:A molten metal 1 of a pure metal or an alloy is injected to the surface of a rotary roll 4 from a nozzle 3 while held to an appropirate temp. by a heater 2 and cooled rapidly to obtain a metal strip 5. To the surface of the roll 4, recessed and protruded parts are provided by forming grooves toward a direction parallel with the axis of the roll 4 or forming curved grooves of which the cross area shape in a peripheral direction is a sine wave form. The cross area shape of the metal strip 5 obtained by this method in a longitudinal direction shows a non-flat shape such as a continuous truncated shape or a sine wave shape. In addition, when the molten metal is solidified, affect of surface tension is made small in a free solidified surface having recessed and protruded parts and, therefore, the thickness of the metal strip is made uniform.

摘要： PURPOSE:To obtain a filter material for a filter capable of purifying contaminated water stably in high reliability, by filling a casing with a diffusion bonded magnetic stainless fiber to increase the strength of the filter material. CONSTITUTION:A casing 20 is filled with a magnetic stainless steel fiber 22 and, after said fiber is degreased with trichloroethylene, it is subjected to intermetallic diffusion bonding in a vacuum heating furnace and thereafter cooled rapidly. Thus obtained filter material is free from the outflow of a metal fiber piece even if filtration and backwashing are repeated compared to a filter material with a conventional structure because of intermetallic diffusion bond and the lowering of filtering capacity.

摘要： PURPOSE:To sufficiently absorb earthquake vibration or environmental vibration, generated in a vibro-isolating quake-isolating bed, by constituting a device alternately piling up an elastic material and a magnetic material and arranging the adjacent fellow magnetic materials so as to attract each other by magnetic force interposing the elastic material. CONSTITUTION:Vibration absorbing units 12 are mounted to a predetermined position on a foundation floor 10. The vibration absorbing unit 12, alternately piling up a rubber plate 14 and a magnetic plate 16, is formed into a column shape. The fellow adjacent magnetic plates 16 are arranged in such a manner as to attract each other by magnetic force interposing the rubber plate 14 in a sandwich state as shown by an arrow head A. In this way, earthquake vibration or environmental vibration, generated in vibro-isolating and earthquake- isolating beds, can be sufficiently absorbed.

摘要： PURPOSE:To enhance the operational efficiency of a magnetic separation apparatus, by forming gap parts to the pole piece and the return frame of the magnetic separation apparatus in a vertical direction to shorten the time constant of excitation and demagnetization of an electromagnet. CONSTITUTION:This magnetic separation apparatus is constituted from a canister 1 containing a filler material 7 comprising a porous magnetic material, a pole piece 2 magnetizing the filler material 7, an electromagnetic coil 4 magnetizing the pole piece 2 and the filler material 7 and return frames 5, 6 surrounding said coil 4. To the pole piece 2 and the return frames 5, 6 slit 8, 9 are vertically formed so as to pierce through the plates thereof in a thickness direction and the gaps between each slits are connected by an insulating adhesive. Therefore, the inductance value of each element is reduced to 1/10 or less while the time constant of an electromagnet is also reduced to 1/10 or less and the opeational efficiency of the magnetic separation apparatus is enhanced to a large extent.
