Abstract: A breast-milk pad can be produced relatively easily, such that it reduces an uncomfortable sensation to the skin surface of a user, and has excellent shape retention properties. A method for producing the breast-milk pad is also disclosed. The breast-milk pad can include a material that is made up by stacking: a back sheet that prevents permeation of liquid; a top sheet that contacts the body; and an absorber that is disposed between the back sheet and the top sheet. The top sheet and the back sheet are bonded to each other in an outer peripheral portion. Cutout portions obtained by cutting the absorber can be formed in positions facing each other at the outer peripheral portion such that cutout width of each of the cutout portions gradually narrows down inwardly.

Abstract: Disclosed in an arrangement to achieve satisfactory head contact by increasing contact face pressure at a head gap and to reduce the change in time of head contact performance in a double azimuth head. Heads in a portion in which a tape is slid are respectively constructed with each head having two different arcs with a radius of curvature R1 in a first area which includes a gap, and with a radius of curvature R2 in a second area which is adjacent to the first area. A transition portion P for transitioning an arc with the radius of curvature R1 and an arc with the radius of curvature R2 is located in the direction of its adjacent head based upon a contact point Q on R1 of a common tangent drawn from an arc forming a periphery of a rotating drum to a circle formed by R1. The relationship between the radiuses of curvature in two areas is set to R1>R2.

Abstract: A ferromagnetic thin film containing Fe as a main component and at least one additive element selected from the group consisting of Co, Ni, Ru, Rh, Pd, Os, Ir and Pt, in which the total content of the at least one additive element is not less than 0.1 at % and additive contents, a, b, c, d, e, f, g and h (at %) respectively of said Co, Ni, Ru, Rh, Pd, Os, Ir and Pt satisfy ##EQU1## The ferromagnetic thin film thus disclosed has a high saturation flux density of 18 KG or more, a magnetostriction constant close to zero, and excellent corrosion resistance. There is also disclosed a magnetic head using the above described ferromagnetic thin film in at least a part of a magnetic circuit thereof.
