20110307212	METHOD AND APPARATUS FOR MEASURING WORKPIECE ON MACHINE TOOL - A measuring head attached to a machine tool is swiveled by a predetermined angle. A reference sphere is then measured by the measuring head from a first direction and a second direction. Accordingly, coordinates of a center point of the reference sphere are acquired. First machine coordinates of the measuring head are coordinates when the measuring head measures the center point of the reference sphere from a first direction. Second machine coordinates of the measuring head are coordinates when the measuring head measures the center point of the reference sphere from a second direction. A 3-dimensional offset of the measuring head is acquired, based on the first machine coordinates and the second machine coordinates of the measuring head. Subsequently, the workpiece is measured by the measuring head, by using the 3-dimensional offset of the measuring head. As a result, the 3-dimensional offset of the measuring head is acquired, and thereby the workpiece can be measured by the measuring head because the measurement function intrinsic to the measuring head is effectively used without separately using another measuring instrument.	12-15-2011

20110108520	Method for manufacturing perpendicular magnetic head including a main pole surrounded by shield layers - A method of manufacturing a perpendicular magnetic head having a writing element that writes magnetic information to a recording medium includes forming a main magnetic pole part generating a magnetic field on a substrate; removing at least a part of the substrate and a material existing at a circumference of the main magnetic pole part to expose an entire circumference of the main magnetic pole part at a surface that becomes an opposing medium surface (ABS) opposite to the recording medium; forming a shield gap film that is made of a nonmagnetic material so as to cover the entire circumference of the main magnetic pole part at least at the surface that becomes the ABS; and forming a shield layer so as to cover an entire circumference of the shield gap film at least at the surface that becomes the ABS.	05-12-2011
20110127234	Method of manufacturing magnetic head for perpendicular magnetic recording with shield around main magnetic pole - A manufacturing method for a magnetic head includes the steps of; forming a structure on a lower shield, the structure including a lower gap, a main magnetic pole and first and second side gaps; forming first and second side shields; forming an upper gap; and forming an upper shield. In the step of forming the structure, an initial lower gap layer is formed on the lower shield, the initial lower gap layer including a pre-lower-gap portion, and two to-be-removed portions that are located on opposite sides of the pre-lower-gap portion. Then, a protrusion including the main magnetic pole and the first and second side gaps is formed on the pre-lower-gap portion. With the top surface of the protrusion covered with a mask, the initial lower gap layer is etched in part to thereby form the lower gap.	06-02-2011
20110240593	METHOD OF FORMING MAGNETIC POLE SECTION OF PERPENDICULAR MAGNETIC RECORDING TYPE THIN-FILM MAGNETIC HEAD AND MANUFACTURING METHOD OF PERPENDICULAR MAGNETIC RECORDING TYPE THIN-FILM MAGNETIC HEAD - A method of forming a magnetic pole section of a perpendicular magnetic recording type thin-film magnetic head and a method of manufacturing a perpendicular magnetic recording type thin-film magnetic head that include forming on an under layer a resist pattern having an opening, forming a first nonmagnetic layer, forming a first magnetic layer, forming a magnetic layer pattern, removing the resist pattern and then applying a resist layer onto a first nonmagnetic layer and a magnetic layer pattern, developing or ashing partway the applied resist layer and baking the remaining resist layer, removing the first nonmagnetic layer from at least a side surface of the magnetic layer pattern by etching with the baked resist layer being left, removing all of the resist layer and then forming a second nonmagnetic layer on at least the magnetic layer pattern, and forming a second magnetic layer on the formed second nonmagnetic layer.	10-06-2011

20080216872	Carburetor, Method of Vaporizing Material Solution, and Method of Washing Carburetor - There is obtained an MOCVD oriented vaporizer which eliminates a phenomenon that thin-film materials are adhered to a portion of the vaporizer near and around a spout thereof. A carrier gas/small amount oxidizing gas supply part supplies a carrier gas, which is supplied through an internally formed gas passage and which contains a material solution, to a vaporization part; a bubble prevention/material solution supply part supplies a material for preventing generation of bubbles of the carrier gas containing the material solution, and the material solution, into the carrier gas; a solvent vaporization restricting/cooling system restricts vaporization of a solvent; and a swirl flow preventing gas supply part supplies a gas for preventing occurrence of swirl flows near a gas outlet of the vaporization part. An atomizing part causes the carrier gas, which contains the material solution and which is ejected from the vaporizer, to be formed into a finely atomized state; and a complete vaporization oriented high performance vaporization tube completely vaporizes the carrier gas ejected from the vaporizer and containing the material solution. This enables long-term usage without clogging and the like, and enables a stable material supply to a reaction part.	09-11-2008
