| 20090279207 | THIN-FILM MAGNETIC HEAD, METHOD OF MANUFACTURING THE SAME, HEAD GIMBAL ASSEMBLY, AND HARD DISK DRIVE - A thin-film magnetic head is constructed such that a main magnetic pole layer having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer on the medium-opposing surface side, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated on a substrate. This thin-film coil has a plurality of turn parts arranged at respective positions having different distances from the medium-opposing surface, while a non-expandable part made of an insulating material having a coefficient of thermal expansion smaller than that of a photosensitive resin is formed between the turn parts. | 11-12-2009 |
| 20090296275 | THIN-FILM MAGNETIC HEAD, METHOD OF MANUFACTURING THE SAME, HEAD GIMBAL ASSEMBLY, AND HARD DISK DRIVE - A thin-film magnetic head is constructed such that a main magnetic pole layer having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer on the medium-opposing surface side, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated on a substrate. This thin-film magnetic head has an equidistant two-stage structure in which a first turn part of a first conductor layer and a second turn part of a second conductor layer overlap vertically along the medium-opposing surface while having the same front distance from respective front side faces closer to the medium-opposing surface to the medium-opposing surface. | 12-03-2009 |
| 20100192343 | METHOD OF MANUFACTURING CERAMIC CAPACITOR - In a method of manufacturing ceramic capacitor according to the present invention, a pair of interdigitated internal electrodes are arranged perpendicularly to the surface of the substrate, subsequent to which the respective end faces of this pair of internal electrodes are exposed, and a pair of external electrodes are formed at these exposed end faces. In this method of manufacturing ceramic capacitor, formation of the external electrodes on the end faces of the respective internal electrodes, with these internal electrodes being interdigitately integrally-formed and the end faces thereof being exposed, it possible to reliably and easily form the external electrodes. | 08-05-2010 |
| 20100195264 | CERAMIC CAPACITOR AND METHOD OF MANUFACTURING SAME - In a ceramic capacitor according to the present invention, an interdiginated pair of internal electrodes are arranged, on a substrate, perpendicular to a surface of the substrate, and a ceramic dielectric member is filled into a gap between this pair of internal electrodes. For this reason, the dimensions of the internal electrodes do not substantially change before and/or after the formation of the ceramic dielectric member, whereby the dimensions formed at the time of internal electrode can be maintained. According to this ceramic capacitor, since the internal electrode dimensions can be easily controlled like this, dimensional control of internal electrode spacing can also be easily carried out. | 08-05-2010 |
