Patents by Inventor Woo-Kyeong Seong

Woo-Kyeong Seong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20020036885
    Abstract: A metal oxide electrode for a supercapacitor and a manufacturing method thereof are disclosed. Potassium permanganate is absorbed on a conductive material, such as carbon or activated carbon, and mixed with a solution including manganese acetate so as to form amorphous manganese oxide. Amorphous manganese oxide powder is grounded to a powder which is mixed with binder to form an electrode having a predetermined shape. The electrode reduces equivalent serial resistance and enhances high frequency characteristics since the contact area and the adhesion strength between the manganese oxide and the conductive carbon are improved. Also, the electrode has high capacitance suitable for a supercapacitor, which is manufactured therefrom at a greatly reduced cost.

  • Patent number: 6088907
    Abstract: A head/slider assembly is integrated with a track-following electrostatic micro actuator. A method for fabricating the head/slider assembly includes the steps of: forming a micro actuator structural layer on a slider substrate with a cavity formed therebetween; forming metal signal lines on the micro actuator structure layer; forming the read/write magnetic head on a central part of the micro actuator structure layer; etching to separate the micro actuator and the read/write magnetic head; and forming a protective cover on top of the micro actuator and the read/write magnetic head to form the head/slider assembly, to thereby make the assembly to allow it to be used in a HDD system of a very high track density having a track pitch of 1 .mu.m and a recording density of more than 10 Gb/in.sup.2.
