Patent number: 8741429Abstract: A fixing heater is provided that employs, as a heating element, a material having small heat capacity and excellent wear resistance. A metal or semi-metal compound that can act as an electrical conduction inhibiting material is mixed into a carbon-containing resin such as a furan resin, chlorinated vinyl chloride resin, etc., and a pattern of a heating element is formed on a substrate, by screen printing, and then is sintered at temperature of about 1000° C. to obtain a fixing heater including amorphous carbon and having NTC characteristics.Type: GrantFiled: January 26, 2012Date of Patent: June 3, 2014Assignee: Mitsubishi Pencil Co., Ltd.Inventors: Noboru Kanba, Yoshihisa Suda

Patent number: 8544595Abstract: A carbonaceous acoustic diaphragm whose density is reduced while retaining the required stiffness is provided. Carbon nanofibers and spherical particles of PMMA are mixed into a carbon-containing resin such as a polyvinyl chloride resin, and the mixture is carbonized to vaporize the spherical particles of PMMA, thereby forming a porous structure having pores with the carbon nanofibers in a powdered form uniformly dispersed through amorphous carbon. By forming a multilayer structure by combining the porous layer with a layer that does not use PMMA, the density can be further reduced while retaining the stiffness.Type: GrantFiled: December 8, 2009Date of Patent: October 1, 2013Assignee: Mitsubishi Pencil Company, LimitedInventors: Takeshi Suzuki, Atsunori Satake, Noboru Kanba, Akihito Mitsui, Yoshihisa Suda
