Abstract: A multilayer magnetic sheet comprises laminate substrates. Each of the laminate substrates is formed in a band shape having a short side and a long side and comprises magnetic strips stacked in layers. The laminate substrates are aligned and arranged in a plate shape in a direction, in which the long sides are adjacent to each other and the short sides extend. The laminate substrates aligned and arranged in the plate shape are stacked in layers in a thickness direction of the laminate substrates. Long side portions of the laminate substrates including the long sides and vicinities of the long sides overlap each other.

A direction in which the long sides of the laminate substrates in the second laminate substrate layer extend intersects a direction in which the long sides of the laminate substrates in the first laminate substrate layer extend.

Abstract: A multilayer magnetic sheet comprises laminate substrates each comprising two or more stacked layers of band-shaped magnetic ribbons. The laminate substrates are arranged side by side in a plate shape in a direction in which long sides of the laminate substrates are adjacent to each other and short sides of the laminate substrates extend. The plate shapes each provided by the laminate substrates arranged side by side are stacked in a thickness direction of the laminate substrate. Ten or more layers of the magnetic ribbons are stacked in total. Positions of the long sides of the laminate substrates adjacent to each other in a direction in which the laminate substrates are stacked are different and separated from each other by 0.5 mm or more in the direction in which the short sides extend.

Abstract: A method for producing a nanocrystalline alloy ribbon having a resin film, the method including a step of preparing an amorphous alloy ribbon capable of nanocrystallization, a step of performing a thermal treatment for nanocrystallization of the amorphous alloy ribbon with tension exerted on the amorphous alloy ribbon, to obtain a nanocrystalline alloy ribbon, and a step of causing the nanocrystalline alloy ribbon to be held on the resin film with an adhesive layer therebetween.

Abstract: To provide an easily releasable adhesive film that can be easily released from an object, to which the film has been bonded, after processing and that does not deform or damage the object when released therefrom. This easily releasable adhesive film is configured by laminating, in the following order, a first film that is thermally shrinkable (a shrinkable film), an adhesive layer that contains a reactive oligomer together with an adhesive, a second film that is not thermally shrinkable (a non-shrinkable film), and an easily releasable adhesive layer. The reactive oligomer is contained in the adhesive layer in an amount of 12 to 130 parts by weight (inclusive) relative to 100 parts by weight of the adhesive. It is preferable that the easily releasable adhesive layer is configured as an easily releasable adhesive layer that is thermally curable/releasable and contains a reactive oligomer together with an adhesive.

Abstract: A floating magnetic head of a monolithic type which is arranged in such a manner that a magnetic circuit is constituted by a first magnetic core having an air bearing surface and a second magnetic core to which a wire is wound and being integrally connected with the first core via a magnetic gap, and the backside of the first core is, connected with an adhesive to a holding member of a cantilever holding structure provided for a load arm in such a manner that the longitudinal central axes of the first core and the holding member coincide with each other. The magnetic head has a groove which is formed on the backside of the first core thereof in such a manner that the groove substantially parallels a magnetic gap line, the groove confronts the holding member and the distance between the gap line and an edge line of the groove adjacent to the gap line is 2 to 20% of the entire length of the first and the second cores. Furthermore, no adhesive adheres to the second core.
