Title: Magnetic head core
Inventor: ISHIKAWA TOSHIO
IPC: G11B5/147
Filed: 1987-06-30
Abstract: PURPOSE:To simplify an assembly operation by forming core pieces by blanking from a plate material formed by laminating and rolling plural high magnetic permeability plate materials deposited with inorg. materials to form nonmagnetic layers on at least one face side. CONSTITUTION:Films are formed by spraying, etc., of a metal oxide 6 of inorg. fine particles consisting of MgO, SiO2, etc., on both or one surface of a hoop material consisting of 'Permalloy(R)' 5 and having 0.1mm thickness and the magnetic cores 7 are blanked by pressing from the plate material 4 formed by laminating such hoop materials to form the core pieces. Since the core pieces 7 blanked from the material 4 in such a manner can be straightly used as the magnetic cores 7, the need for adhering and laminating stages after blanking as in the conventional practice is eliminated and the stage for operation is greatly shortened. The cores 7 are then annealed. The problem that the deviation in the relative positions of the 'Permalloy(R)' 5 arises is eliminated with the cores 7 formed in such a manner. The magnetic head having the good characteristics is thus obtd.

Title: Liquid phase epitaxial growth
Inventor: KISHI YUTAKA
IPC: C30B19/12
Filed: 1980-11-21
Abstract: PURPOSE:To prevent a misfitted transfer from extending in the direction of a central part, by a method wherein auxiliary substrates are placed in an adjoining manner at opposing sides at two sides, where a misfitted transfer is susceptible to produce, of a compound semiconductor layer growing on a substrate to be processed. CONSTITUTION:Auxiliary substrates 6, 6' are placed in an adjoining manner at both sides of a substrate 3 to be processed placed in a concavity 5 in a boat base 1. The auxiliary substrates 6, 6' are required to have a grid constant being approximately equal to that of the substrate 3. The auxiliary substrates 6, 6' are positioned in an adjoining manner at opposing sides at the two sides, paralleling a slider's movement direction shown in an arrow mark, out of the 4 sides of the substrate 3. In the substrate 3 in a surface orientation 100, a misfitted transfer is hard to extend in a 110 orientation and easy to extend in a 1-10 orientation. Provided the direction of the two sides in the direction of the arrow mark is 110, the two sides, being in the direction perpendicular to the direction of the arrow mark, are in the direction of 1-10. Thus, if an epitaxial layer is formed on the substrate 3 without the use of the auxiliary substrates 6 and 6', a misfitted transfer, produced at the two sides in the direction of the arrow mark, extends widely toward the center, and the installation of the auxiliary substrates 6 and 6' permits the suppression of said extension.
