Title: Magnetic head device
Inventor: KONISHI KATSUO
IPC: G11B5/53
Filed: 1988-07-01
Abstract: PURPOSE:To simplify assembly work by integrally aligning at least two heads to a gap line, and differentiating gap lengths conforming to functions. CONSTITUTION:Two magnetic heads 2 and 2' to be mounted on a rotary body are integrally formed on a single substrate 1 by means of thin film technique, and the magnetic gaps are aligned so as to mutually make a straight line. The respective magnetic gap lengths are mad so as to be fit for the respective functions, and for example, the recording and erasing gap length is made longer than the reproducing gap length. In addition, an erasing and recording head track width is made broader than a reproducing track width. Thus, the respective heads are made fit for the respective functions, at the time of the assembly, the plural heads are unnecessary to be individually mounted, and the assembly work is simplified.

Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To shorten processing time required for reading a data block whose quality is deteriorated owing to dirt adhered to the surface of a medium at the reading of the data block from the medium and to improve transfer rate. SOLUTION: The data block which is read from the medium 1 by a signal read part 2 is error-corrected by an error correction part 3 and is stored in a main storage device 5. The stored data block is transferred to an external bus through an I/F control part 4.

Title: Bound insulation cable and deflection yoke using same
Inventor: TATSUNO TAKAHIKO
IPC: H01J29/76
Filed: 1989-06-26
Abstract: PURPOSE:To reduce the amount of heat generated in association with high frequency resistance loss and improve reliability and productivity by binding a plurality of naked conductors in an approximate cross-sectional shape as a core conductor and disposing an insulation coating over the core conductor by applying and baking an insulation paint around the outer surface of the bound cables. CONSTITUTION:A collective conductor 4 is made by binding a plurality of naked conductor wire 3 in parallel in an approximate cross sectional shape or by roughly twisting a plurality of naked conductor wires 3 in approximately circular cross sectional shape. An insulation paint is applied and baked around the circumference of the collective cable 4 to form a collective insulation cable 1 coated with an insulation film 6. Because the collected conductor wires 3 are conductive to each other, high frequency eddy current is produced in the collective conductor 4. A point contact conductivity is made in the cross section between adjacent naked conductor wires 3 because the wire is of a circular cross section. As a result, electric resistance of the eddy current in the collective conductor 4 is high and the eddy current is suppressed low. As a result, heat amount generated due to high frequency resistance loss is reduced as a whole.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of reducing hillocks to be a problem especially at the time of using an Al thin film as a wiring material, in the manufacturing method of an Al or Al alloy wiring film. SOLUTION: When contamination for which the oxidative gas of oxygen or water or the like remains inside a processor at the time of sputtering for forming the Al thin film is generated, an oxidized film is formed at the grain boundary of the Al film, the growth of grains is obstructed and the hillock is generated on the surface of the Al thin film in a heating process thereafter. In order to prevent that, in this case, before growing the Al thin films 5a and 5c on a substrate 5, high frequency power weak enough not to sputter a target 3 is supplied to the target 3, plasma is generated, the surface of the target 3 and the surface of the substrate 5 are cleaned and the oxidative gas is removed.  Thus, the oxidized film is prevented from being formed at the grain boundary, the growth of the grains is not obstructed and the generation of many hillocks on the surface is prevented even when a heating processing is performed after forming the thin film.
