Title: Thin-film magnetic head
Inventor: YAMAZAKI SHIYUUSUKE
IPC: G11B5/31
Filed: 1981-10-06
Abstract: PURPOSE:To increase the adhesive strength between a magnetic material and a winding conductor, to obtain high work precision, and to facilitate the coating of an insulating layer, by employing the two-layered structure, formed by stacking a ''Permalloy '' thin film and a copper thin film successively, to a base layer for electrodeposition of the winding conductor of a thin-film magnetic head. CONSTITUTION:On a magnetic material substrate 1, a ''Permalloy '' layer 2a' is vapor-deposited to a 100Angstrom  thickness, and then a copper layer 2b is vapor-deposited to a 1,000Angstrom  thickness to form a base layer of two-layered structure for electrodeposition. A prescribed pattern is obtained by photoetching. During this etching, the end part of the permalloy layer 2a' is never etched more inside than the end part of the copper layer 2b to allow the layer 2b to project in a pent roof shape. Therefore, when a conductor (copper) layer 2c for winding is electrodeposited next, the layer 2c has no defective adhesion part on the substrate 1, and on the layer 2c, an insulating layer is formed thinly and excellently by vapor-depositing SiO2, etc. Thus, the thin-film magnetic head is formed at high yield with good precision.

Abstract: PURPOSE:To reduce noise and prevent the reduction in attracting force by providing plural recessed rings for receiving foreign material on the outer peripheral edge parts respectively attached to the end faces of a fixed iron core or a plunger. CONSTITUTION:Recessed rings 3b, 3d or receiving foreign material are formed on the outer peripheral edge parts respectively attached to the end faces of a plunger 30 and a fixed iron core 34a. When the attracting action of the plunger 30 begins, the oil-gas stored between the plunger 30 and the fixed iron core 34a flows into a bypass hole 30a and the clearance between the plunger 30 and a cylinder 32 due to then reduction in volume. At this time the foreign materials in the fluid flowing into the clearance-side are trapped in the recessed rings 30b, 34d of larger cross-section than that of the clearance when the flow- speed is once slowed down.

IPC: H01L21/768
Filed: 1988-06-28
Abstract: PURPOSE:To perform interlayer connection of a low resistance by forming a W film after making a connecting hole and causing an unnecessary part of the W film to be insulated simultaneously with etchback of a resist layer, thereby performing filling up with W obtained by a selective growth after leaving the W film surely on the bottom of the connecting hole. CONSTITUTION:An Al wiring pattern 2 is formed on the surface of a semiconductor substrate 1 and a connecting hole 4 is opened after coating it with a PSG layer 3. A W film 5 is formed by depositing it through sputtering to spin- coat a resist 6. Once it is treated by etching, the resist 6 is removed and subsequently, even the exposed W film 5 is oxidized to be formed into a WnOm like insulating oxide 7. Even though a part of the resist 6 in the opening is removed, its part 6' to coat the bottom of the hole remains. When the resist 6 is removed by a solvent, the film W 5 is deposited only at the bottom of the opening. Interlayer connection of a low resistance is thus performed.

Abstract: PROBLEM TO BE SOLVED: To shorten a toner transfer time and lessen a delay in fixing of toners, by applying intermittent control pulses in a print state and forming the intermittent control pulses to change at least between two levels. SOLUTION: A first short pulse (a) releases many toner particles from a particle source, e.g. a developer sleeve, and a succeeding second pulse (b) having an opposite polarity returns the toner particles to a layer where the toner particles on a surface of the developer sleeve are present. A turbulence brought about by the toner particles returned into the toner layer functions along with a pulse (d) to release fresh toner particles. The pulse (d) has the same polarity as the pulse (a) and a longer duration time than the pulse (a). The toner particles present much deep in the toner layer receive a mechanical assistance to lower o required release force. The pulse (d) causes toner particles to emit from the developer sleeve.
