Title: Composite magnetic head and its manufacture
Inventor: WATANABE SATOSHI
IPC: G11B5/23
Filed: 1986-05-19
Abstract: PURPOSE:To easily manufacture a head with high moisture resistance and high abrasion resistance by jointing heat-treated metallic magnetic cores to cores made of oxide at an gradient angle approximately the same as an azimuth by means of a nonmagnetic body with high melting point. CONSTITUTION:The metallic magnetic cores 53 and 54 being a main core, which are formed from a metallic piece layer forming a gap 70 and heat-treated, are arranged at the gradient angle approximately the same as the azimuth thetawith respect to the oxide magnetic cores 55-58 being a subcore located on both sides. The cores 55-58 and the cores 53 and 54 are jointed on the tape slide surface by the high melting point nonmagnetic body 71. With the arrangement of the cores 53 and 54 the gap 70 can be formed at a right angle on the surfaces of the cores 53 and 54 regardless of the azimuth, thereby easily manufacturing the cores 53 and 54 including core piece laminated layers. Besides the high melting point linkage material can prevent linkage materials from being damaged. Thus the composite magnetic head with high moisture resistance and high abrasion resistance can be easily manufactured.

IPC: B29B13/08
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To improve the extrusion-stability of a product without the development of whitening and void and the abnormality of its transparency and shape by a method wherein a saponified ethylene-vinyl acetate copolymer is dried by being irradiated with microwaves. SOLUTION: A saponified ethylene-vinyl acetate copolymer EVOH employed has an ethylene content of 10-60 mol.% and the degree of saponification of 90 or more mol.%. The preferable water content of the dried EVOH, microwaves are irradiated. The above drying method can also be employed for drying after the processing of the EVOH pellets with various aqueous solutions or the molding of the EVOH product as well as at the manufacturing of the EVOH. Thus, since no phenomena such as the development of whitening or voids occurs in the dried EVOH, the resultant EVOH is excellent in transparency, non-deformation or the like.
