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&#xb0; C. to obtain a fixing heater including amorphous carbon and having NTC characteristics.

Fixing heater and manufacturing method thereof

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.

Carbonaceous acoustic diaphragm and method for manufacturing the same

In order to provide a separator for a fuel cell which is improved in cell characteristics by controlling a wetting property of the separator for a fuel cell and a production process for the same, assumed is a constitution in which in a separator A for a fuel cell molded from at least from a carbon material, a hydrophilic functional group is formed and increased on a surface part of a flow passage surfacein the separatorby irradiation treatment of a YAG laser apparatusand in which an uneven part having an average surface roughness Ra of less than 50 &#x3bc;m is formed.

Separator for fuel cell and production process for the same

Disclosed is a vehicle lamp that is designed to reliably remove snow, etc. adhering to a lens. A carbon-based heating element is mounted within a lamp body so that the heat rays radiated from the heating element irradiate a rear surface of the lens.

Vehicle lamp

A resistive heating element having high generation efficiency for far infrared rays and a comparatively high specific resistance while maintaining the strength required as a resistive heating element, is obtained by shaping a mixture of graphite powder, boron nitride and silicone rubber to a desired shape followed by firing by heating to 380&deg; C. in an oxidizing atmosphere and then further firing by heating to 1100&deg; C. in a nitrogen atmosphere.

Resistive heating element and production method

A method for simplified sterilization is provided which does not use a harmful medium such as a disinfectant and ultraviolet radiation and which is able to reach all portions of objects to be sterilized, where sterilization is realized without high temperatures being generated. After applying a small amount of water or mixture of water and ethanol to an object to be sterilized, or after spraying a liquid gas, far-infrared radiation is applied using a carbon lamp which has high far-infrared radiation efficiency.

Baked colored pencil lead and process for producing the same

Carbonization is achieved and impurity elements are removed by combination of a metal or metalloid compound with a composition exhibiting a carbon residual yield that is substantially not zero after firing, followed by firing at a pressure of no higher than 1&times;10 Pa and a temperature of from 1500&deg; C. to 2200&deg; C.
