Patent application numberDescriptionPublished
20090004730Cell Obsevation Aiding Instrument and Method of Cell Observation Therewith - A cell observation support instrument having opposed first and second surface members 01-01-2009
20090121606ELECTRON EMISSION SOURCE - An electron emission Source is disclosed, in which the fine carbon fibers included are uniformly dispersed as compared with those in the conventionally known electron emission sources, and the manufacturing of which is also easy.05-14-2009
20090124746THERMOPLASTIC ELASTOMERIC COMPOSITION - A thermoplastic elastomeric composition which have an improved compression set and good electrical properties is provided.05-14-2009
20090131575COLORED POLYMER COMPOSITION - The disclosed is a colored polymer composition which includes carbon fibrous structures and a coloring agent in a polymer matrix, wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part with which the carbon fibers are tied together in the state that the concerned carbon fibers are externally elongated therefrom, and wherein the granular part is produced in a growth process of the carbon fibers. It is the colored polymer composition which includes novel carbon fibrous structures having preferable physical properties as a filler for composite material, and of being able to improve electrical, mechanical and thermal properties of a matrix while maintaining other properties of the matrix, in a small adding amount, and which can show a color as pleases. When a white coloring agent is used as the coloring agent, the darkness in color tone of the polymer which is due to the addition of the carbon fibrous structure can be easily corrected by adding a relatively small amount of the white coloring agent as the coloring agent.05-21-2009
20090152508CONDUCTIVE COATING MATERIAL - The disclosed is a conductive coating material which includes an organic binder component and carbon fibrous structures, wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part with which the carbon fibers are tied together in the state that the concerned carbon fibers are externally elongated therefrom, and wherein the granular part is produced in a growth process of the carbon fibers; and wherein the carbon fibrous structures are contained at a rate of 0.01-50% by weight based on the total weight of the coating material. The conductive coating material gives a coated film which shows a high electrical conductivity and a good film strength, and also coordinates its color as an intended one easily.06-18-2009
20090226712RECYCLED COMPOSITE MATERIAL - An recycled composite material is disclosed, which is prepared by using as a raw material a waste composite material which comprises a matrix component and carbon fibrous structures added to the matrix, and adding an additional matrix component which is homogeneous and/or heterogeneous with the matrix of the spent composite material, and then kneading them together; wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers, each carbon fiber having an outside diameter of 15-100 nm, and a granular part, at which the fibers are bound in a state that the carbon fibers extend outwardly therefrom, and wherein the granular part is produced in a growth process of the carbon fibers. The recycled composite material performs much the same with the original composite material, and is produced briefly at a low cost.09-10-2009
20090263642ELECTRICALLY CONDUCTIVE SHEET - The disclosed is an electrically conductive sheet which includes carbon fibrous structures in polymer matrix, at a rate of 0.01-30% by weight based on the total weight of the sheet, wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part with which the carbon fibers are tied together in the state that the concerned carbon fibers are externally elongated therefrom, and wherein the granular part is produced in a growth process of the carbon fibers. The electrically conductive sheet shows a high electrical conductivity while possessing a good film strength.10-22-2009
20090292057COMPOSITION FOR REACTIVE INJECTION MOLDING AND REACTIVE INJECTION MOLDED ARTICLE - A composition for injection molding by which a reactive injection molded article of good mechanical strength and electrical conductivity is prepared is provided.11-26-2009
