Title: Composite coil
Inventor: TANZAKI MASUMI
IPC: H01F17/04
Filed: 1978-11-14
Abstract: PURPOSE:To provide a composite coil not having mutual interference by winding a part of one coil close to the other and in the reverse polarity while both coil windings are separated by the flanges on the same drum core. CONSTITUTION:The drum core 1 has the top 2, middle 2', and bottom 2'' flanges. A composite coil is formed by winding the first coil L1 on the core 1 between the flanges 2 and 2', the second coil L2 between the flanges 2' and 2''. At the same time, the auxiliary coil L3 which is a part of the second coil L2 is wound on the core 1 between the flanges 2 and 2' near the coil L1 and in the reverse polarity. This causes loose coupling M1 and M3 to form between the coil L1 and L2 as well as between L2 and L3, and close coupling M2 to form between the coil L2 and L3. The connection cancels inductive voltage due to mutual action of the coil L1 and L2 and provides a composite coil free of relative influence while using two sets of coils wound on the same core.

Title: Production of thin-film magnetic head
Inventor: NAGAI HIDEYASU
IPC: G11B5/31
Filed: 1990-05-29
Abstract: PURPOSE:To obtain the taper of an insulating layer consisting of SiO2 at a good yield by etching the insulating layer formed by using RIE. CONSTITUTION:The insulating layer 13 is subjected to the etching by using the RIE. An undercut is suppressed low and the insulating layer 13 of the SiO2 is etched if the RIE is used in such a manner. An etching gas of a fluorine system and the SiO2 come into reaction at this time and are discharged in the form of gaseous SiF4 and, therefore, the resticking of the etched insulating layer to a substrate does not arise. Since the RIE is reactive, the resist 14 formed on the insulating layer 13 is more hardly etched than the insulating layer 13 of the SiO2 conversely from ion milling and the absolute quantity of the resist 14 to be etched is decreased. The taper of the insulating layer 13 consisting of the SiO2 is obtd. at the good yield in this way.
