A brush, for use for example as an electrical pick-up, includes a brush portion composed of a bundle of metal coated carbon fibers arranged substantially in parallel. A base portion includes a region where the metal coated fibers have been bonded by diffusion via a hot pressing method, and at least one metallic piece bonded to the fiber bundle by diffusion by the same process. The brush of the invention has excellent durability and a conductivity.

Brushes and method for the production thereof

A method for manufacturing activated carbon fibers is disclosed. The method is comprised of the steps of:

Method for manufacture of activated carbon fiber

A fibrous activated carbon with a metal chelate compound supported thereon which is suitable for removal of toxic substances in gas. This activated carbon is obtained by attaching a solution or dispersion of the metal chelate compound onto the fibrous activated carbon followed by drying. Contacting the activated carbon with a toxic substance-containing gas provides very efficient removal of the toxic substance from the gas.

Fibrous activated carbon with metal chelate compound supported thereon,

A fibrous activated carbon having high adsorptivity and excellent mechanical properties is produced by preoxidizing an acrylonitrile-based fiber containing a specific amount of an iron compound at a specific initial heat-treatment temperature and then activating.
