The semiconductive resin composition of the present invention can be used widely in various form of molded products, such as component used for transport in a clean room, spin chuck, IC test socket, various rollers installed in copier, seamless belt, bearing, antistatic fiber, member for electrostatic coating, fuel tube, part around fuel or chemical tube. | 07-08-2010 |
| 20100039730 | MAGNETIC RECORDING MEDIUM, METHOD OF MANUFACTURING THE SAME, AND MAGNETIC RECORDING/REPRODUCING APPARATUS - The present invention provides a magnetic recording medium which is capable of improving the perpendicular orientation of a perpendicular magnetic recording layer while maintaining a writing performance during recording and obtaining both an improvement in the perpendicular orientation and fine magnetic crystal particles with a uniform diameter, and which enables information to be recorded or reproduced at high density, a method of manufacturing the same, and a magnetic recording/reproducing apparatus. A magnetic recording medium | 02-18-2010 |
| 20100033873 | MAGNETIC RECORDING MEDIUM, METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING REPRODUCING APPARATUS - In a perpendicular magnetic recording medium in which at least a soft magnetic underlayer, an orientation control layer, a magnetic recording layer and a protective layer are formed on a non-magnetic substrate in order from the bottom, the orientation control layer has a laminated structure of two or more layers including an intermediate layer and a seed layer which is disposed closer to the non-magnetic substrate than the intermediate layer. The seed layer includes two or more kinds of elements having a face-centered cubic structure, has face-centered cubic (111) plane crystals oriented in a direction perpendicular to a substrate surface, and has a pseudo-hexagonal structure. | 02-11-2010 |
| 20100007985 | METHOD FOR PRODUCING MAGNETIC MEDIUM, MAGNETIC RECORD REPRODUCTION DEVICE, AND MAGNETIC RECORDING MEDIUM - One object of the present invention is to provide a method for producing a magnetic recording medium which has excellent magnetic separation properties of the magnetic recording pattern, the present invention providing a method for producing a magnetic recording medium having a magnetic recording pattern which is magnetically separated, comprising the steps of: after laminating at least a magnetic layer and a carbon protective layer on a non-magnetic substrate in this order, partially irradiating with a reactive plasma containing carbon and a halogen or reactive ions which are generated in the reactive plasma on a surface of the carbon protective layer, and thereby forming a halogenated carbon protective layer, which is obtained by partially halogenating the carbon protective layer, and the magnetic recording pattern separated magnetically which is obtained by partially improving the magnetic layer. | 01-14-2010 |
| 20090324813 | IN-LINE FILM FORMING APPARATUS AND MANUFACTURING METHOD OF MAGNETIC RECORDING MEDIUM - An in-line film forming apparatus capable of conveying a carrier at a high speed, increasing the exhaust capability within a film forming chamber, and easily realizing a high vacuum degree in a short time is provided. A conveyor mechanism has a linear motor drive mechanism which drives the carrier in a noncontact state, a horizontal guide mechanism which is provided so as to be able to contact a side portion of the carrier, and guides the carrier driven by the linear motor drive mechanism in a horizontal direction, and a vertical guide mechanism which is provided so as to be able to contact a lower end of the carrier, and guides the carrier driven by the linear motor drive mechanism in the vertical direction. | 12-31-2009 |
| 20090290292 | CAPACITOR CHIP AND METHOD FOR MANUFACTURING SAME - The present invention relates to a capacitor chip and a solid electrolytic capacitor, wherein in a capacitor chip in which one or more capacitor element is laminated on a metal lead frame to carry electricity and the whole is encapsulated with resin, a laminated body is located within a certain definite range. The present invention enables to increase the capacitance of a capacitor by broadening the allowable range of the total thickness of the laminated capacitor chips without generating defective appearance of the laminated solid electrolytic capacitor. | 11-26-2009 |
| 20090149676 | METHOD OF MANUFACTURING 3, 3' , 4, 4'-TETRAAMINOBIPHENYL - An object of the present invention is to provide an efficient method of manufacturing 3,3′,4,4′-tetraaminobiphenyl with a smaller number of steps. The manufacturing method of 3,3′,4,4′-tetraaminobiphenyl includes reacting the amino groups of a 4-halo-o-phenylenediamine with an inorganic sulfur compound to lead to a 5-halo-2,1,3-benzothiadiazole, subsequently coupling two molecules of the benzothiadiazole together to form a 5,5′-bis(2,1,3-benzothiadiazole) and then deprotecting the amino groups to yield 3,3′,4,4′-tetraaminobiphenyl. | 06-11-2009 |
