Abstract: A vehicle seat includes: a seat frame; a seat pad; and a planar body configured to support, from a backside, the seat pad, and including a high-elongation part more easily extensible than other planar-body part. The planar body includes a low-density region, a high-density region, and a medium-density region in which constituent yarns are placed more thickly than the low-density region, but more thinly than the high-density region, the medium-density region being provided between the low-density region and the high-density region adjacent to each other. The low-density region is placed in the high-elongation part so that the high-elongation part is easily extensible. The high-density region and the medium-density region are placed in the other planar-body part so that the other planar-body part is less easily extensible. The medium-density region in the other planar-body part is adjacent to the high-elongation part.

Abstract: A thin-film piezoelectric material element includes a piezoelectric part having a laminated structure which a lower electrode film, a piezoelectric material film and an upper electrode film are laminated sequentially, and electrode pads connected with the piezoelectric part. The thin-film piezoelectric material element has solder regulating parts formed on pad surfaces being surfaces of the electrode pads. The solder regulating parts have peripheral edge parts and crossing edge parts connected with the two outer edge parts, and formed to cross the pad surfaces. The crossing edge parts are formed in a bow like curve-shape having curved parts, being gradually distant from the shortest line as they are distant more from the outer edge parts.

Abstract: A thin film piezoelectric element of the present invention includes a substrate and a piezoelectric thin film stack formed on the substrate. The piezoelectric thin film stack includes a top electrode layer, a bottom electrode layer and a piezoelectric layer sandwiched between the top electrode layer and the bottom electrode layer, wherein the piezoelectric layer includes a first piezoelectric layer and a second piezoelectric layer whose compositions have different phase structures. The present invention can obtain high piezoelectric constants, enhanced coercive field strength and good thermal stability, thereby enabling larger applied field strength without depolarization and achieving a large stroke for its applied device.

Abstract: A method of manufacturing a perpendicular magnetic write head capable of precisely narrowing a side gap is provided. A tip portion having a cross sectional geometry of an inverted trapezoid is formed in an opening portion of a non-magnetic layer and thereafter, the non-magnetic layer is etched with the tip portion as a mask. Thereby, a portion adjacent to the tip portion in a writing track width direction remains and an outermost edge portion of the tip portion in that direction is located on a plane which coincides with an etching face (side face) of the non-magnetic layer. When a gap layer is formed with a vapor phase growth such as a sputtering method to cover the side face of the non-magnetic layer and thereafter a side shield layer is formed adjacently to the tip portion therethrough, a thickness of the gap layer becomes extremely thin and is reproduced precisely. Therefore, the side gap is narrowed with high precision.

Abstract: A perpendicular magnetic write head includes: a magnetic pole; a pair of nonmagnetic side gap layers provided on both sides in a track-width direction of the magnetic pole; a nonmagnetic trailing gap layer provided on a trailing side of the magnetic pole; a magnetic shield layer so provided as to surround the magnetic pole with both of the nonmagnetic side gap layer and the nonmagnetic trailing gap layer in between; and a magnetic seed layer formed between the nonmagnetic trailing gap layer and the magnetic shield layer, and having a saturation magnetic flux density higher than that of the magnetic shield layer. The magnetic seed layer is not formed between the nonmagnetic side gap layer and the magnetic shield layer.

Abstract: A method of manufacturing a perpendicular magnetic recording head capable of easily and accurately forming a main magnetic-pole layer having a shape suitable for concentrating a magnetic flux is provided. A nonmagnetic layer having a recessed section (a first recessed section and a second recessed section) is formed, and then an additional nonmagnetic layer is formed on an inner surface of the recessed section. Then, a magnetic layer is formed in the recessed section formed with the additional nonmagnetic layer, and then the magnetic layer is cut to form an air bearing surface, so as to form the main magnetic-pole layer.

Abstract: A perpendicular magnetic write head capable of suppressing damage and corrosion of a magnetic pole to secure a stable writing performance is provided. A non-magnetic protruding layer protruding from a main magnetic pole layer (tip portion) toward an air bearing surface side is formed on both sides of the tip portion in a writing track width direction. The non-magnetic protruding layer is located closer to a recording medium than the tip portion during writing operation, and is more likely to be in contact with the writing medium instead of the tip portion. Since the protective film portion covering the tip portion hardly peels off (e.g., compared to the protective film portion covering the non-magnetic protruding layer), the tip portion is hardly damaged or corroded. Since the tip portion is protected physically and chemically by the non-magnetic protruding layer, deterioration of the soft magnetic characteristics of the tip portion is suppressed.

Abstract: A perpendicular magnetic write head in which unintended erasure of information at the time of non-writing can be suppressed while keeping the capability of writing is provided. The perpendicular magnetic write head includes a magnetic pole tip portion, a first yoke portion connected to the magnetic pole tip portion, having a width larger than that of the magnetic pole tip portion, and having a recess portion in a center region thereof, and a second yoke portion embedded in the recess portion. The magnetic pole tip portion and the first yoke portion are integrally formed with a vapor deposition method, and the second yoke portion is formed with a plating method. Since the saturation flux density of the magnetic pole tip portion formed with the vapor deposition method becomes higher than that of the yoke portion, a magnetic flux intake capacity of the magnetic pole tip portion is ensured.

Abstract: The invention is to permit a bushing main body of rubber elastomer to be adhered to a bar member while retaining a necessary contact pressure for adhering and after adhering, to permit a further compressive force to be imparted. The bushing main body (10) having a bore (11), through which the bar member (B) passes, and a bracket (20) holding the former are longitudinally split into two, respectively, the resulting split rubber bodies (10a)(10b) are vulcanization bonded to inner peripheral surfaces of the resulting half bracket members (20a)(20b). The inside diameter (D1) of both split rubber bodies as molded is made smaller than the outside diameter (D2) of the bar member, and inner peripheral surfaces (11a)(11b) at the bore are formed to be eccentric on mutually opposite sides.
