Patent number: 8323726Abstract: When a surface of magnetic carrier core particles is coated with coating resin composition particles, the coating is conducted so that a surface of the magnetic carrier is free from cracks and chips and has fewer residual resin composition particles and a coating is uniform. In the method, a rotor having a plurality of stirring members on a surface thereof is rotated to coat the surface of magnetic carrier core particles with the resin composition particles. When the coating is conducted, while repeatedly conducting transportation in a direction of a driver and transportation in an anti-driver direction, the surface of the magnetic carrier core particles is coated with the resin composition. The resin composition particles has a 50% particle diameter (D50) based on volume of 0.2 ?m or more to 6.0 ?m or less and the proportion of particles of 10.0 ?m or more is 2.0% by volume or less.Type: GrantFiled: October 7, 2010Date of Patent: December 4, 2012Assignee: Canon Kabushiki KaishaInventors: Takeshi Naka, Yoshinobu Baba, Koh Ishigami, Yoshiaki Shiotari, Kentaro Kamae

Patent number: 8323727Abstract: A method for manufacturing a magnetic write head that has a trailing magnetic shield with a tapered write pole trailing edge, a non-magnetic step layer and a Ru bump and an alumina bump formed at the front of the non-magnetic step layer. The process forms a Ru/alumina side wall at the sides of the write pole, such that the Ru side wall is closest to the write pole. The Ru is removed more readily than the alumina during the ion milling that is performed to taper the write pole. This causes the Ru portion of the side wall to taper away from the write pole rather than forming an abrupt step. This tapering prevents dishing of the trailing edge of the write pole for improved write head performance.Type: GrantFiled: December 17, 2009Date of Patent: December 4, 2012Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Aron Pentek, Yi Zheng

Patent number: 8318239Abstract: The embodiments of the present invention provide a defect detection process and apparatus to detect defects in solar cell structures. During the process, an input signal from a signal source is applied to a top surface of a transparent conductive layer of a solar cell structure. In response to the input signal, an output signal is generated from a predetermined area of the top surface and detected by a defect detector. The output signal carrying the defect position information is transmitted to a computer and registered in a database. With the position information, an injector is driven to the defect location to apply an insulator to passivate the defect. A finger pattern layer may be formed over the predetermined area after completing the defect detection and passivation processes.Type: GrantFiled: November 17, 2008Date of Patent: November 27, 2012Assignee: SoloPower, Inc.Inventors: Bulent M.

Patent number: 8313799Abstract: Adhesive compositions useful for bonding fluorescent material-containing cellulosic substrates such as envelopes may be formulated using an adhesive polymer such as an emulsion of polyvinyl acetate in water and one or more compounds capable of reducing the degree of fluorescence exhibited by the substrate in areas of the substrate surface having the adhesive coated thereon. When irradiated by short wavelength light, the surface areas containing the adhesive coating appear darker than the surface areas that are free of adhesive, allowing quality control problems associated with application of the adhesive to be readily monitored and corrected. At the same time, however, the adhesive may be formulated such that the fluorescence-reducing compound does not alter the appearance of the adhesive coating when viewed under normal daylight conditions.Type: GrantFiled: November 30, 2009Date of Patent: November 20, 2012Assignee: Henkel CorporationInventors: Vincent A.
