| 20110045506 | Chemiluminescent Enzyme Assay Method and Apparatus - A chemiluminescent enzyme immunoassay method for quantifying antigen or antibody using 1,1′-oxalyldiimidazole (ODI) derivative or 1,1′-oxalyldisodium benzoate (ODB) derivative chemiluminescence (CL) detection was developed. Also, various enzymes were quantified using ODI derivative or DOB derivative CL detection. Fluorescent compound formed from a substrate (non-fluorescent compound) through the enzyme assay methods emitted CL when the fluorescent compound received energy from high-energy intermediate formed in ODI derivative or ODB derivative CL reaction. | 02-24-2011 |

| 20100325555 | Method and Apparatus for Providing Auto-Registration and Service Access to Internet Sites for Internet Portal Subscribers - A method and apparatus is provided for populating and submitting electronic forms by proxy over a data-packet-network. The apparatus comprises a software application running on a system of network-connected servers that enables a user, connected in session with one of the servers, to navigate to a site containing an electronic form and obtain data about the site and about the form. The data obtained is used in conjunction with data about the user to construct a machine readable job order upon user request that may be executed for the purpose of automatic form population and submission to a host sponsoring the site. Upon acceptance of the submitted form, data used for passwords, log-in codes and user-names is returned to a data repository where it is entered along with specific site data as a new registered site item for a registering user such that future navigation to the site, auto log-in and data return may be performed automatically on behalf of the user. | 12-23-2010 |

| 20100196681 | METHOD OF FORMING METAL WIRING AND METAL WIRING FORMED USING THE SAME - Disclosed are a method of forming metal wiring and metal wiring formed using the same. The method includes printing wiring using an ink composition including metallic nanoparticles and dispersants maintaining dispersion of the metallic nanoparticles, performing a first firing process of firing the wiring under vacuum or in an inert atmosphere to suppress grain growth, and performing a second firing process of firing the wiring with the vacuum or inert atmosphere released, to accelerate grain growth. The method of forming metal wiring induces abnormal grain growth by rapidly removing dispersants, capable of inducing the growth of metallic nanoparticles, at a temperature at which the growth force of the metallic nanoparticles is high, in the process of firing the metallic nanoparticles. Accordingly, the metal wiring has a coarse-grained structure containing metallic particles with a large average particle size, and the electrical and mechanical characteristics thereof can be enhanced. | 08-05-2010 |

| 20090246673 | Method for Manufacturing a Toner Having Good Charging Characteristics - There is provided a toner having good charging characteristics that is composed of a core region and a thin shell in which a charge control agent is densely distributed so as to improve charging characteristics of the toner, and a method for manufacturing the same. The method for manufacturing a toner having a bi-layered structure includes: producing a toner core using a suspension polymerization method; preparing a suspension of toner particles having a core-shell structure by forming a rigid shell on a surface of the toner core; and recovering the toner particles from the suspension as a post-processing operation. | 10-01-2009 |
| 20090280430 | Method for Manufacturing Toner - There is provided a method for manufacturing a toner capable of providing a toner having excellent low-temperature fixing property and anti-offset property by adjusting a molecular weight distribution of a polymerization toner to a narrow distribution range. The method is characterized in that a toner is polymerized using a reversible addition-fragmentation chain transfer polymerization (RAFT) method by adding a dithioacetate, xanthate or dithioester-based chain transfer agent in the polymerization of a toner. The method for manufacturing a toner comprises: dissolving a dispersant in water to prepare an aqueous dispersion solution; mixing a binder resin monomer, a charge control agent, a pigment, a wax and a dithioacetate, xanthate or dithioester-based chain transfer agent to prepare a monomer mixture; adding the monomer mixture to the aqueous dispersion solution and suspension-polymerizing the monomer mixture to form a toner composition; removing the dispersant from the toner composition; and drying the dispersant-free toner composition under a vacuum condition. | 11-12-2009 |
| 20100190103 | METHOD OF PRODUCING POLYMERIZED TONER - Disclosed is a method for producing a polymerized toner. In the method, a mixture of colloidal silica as an aqueous dispersant and a polyvinylpyrrolidone is used during suspension polymerization. The amount of polyvinylpyrrolidone/colloidal silica aggregates having a diameter smaller than 100 nm is also limited to 1% by weight or less, based on the total weight of all aggregates. A polymerized toner produced by the method has a volume average particle diameter (dv) of 5 to 10 μm and a volume average particle diameter/number average particle diameter ratio (dv/dp) of 1.5 or less. The polymerized toner is consumed in a small amount during printing. According to the method, the formation of emulsion particles having a size smaller than 0.5 μm is inhibited. | 07-29-2010 |
