Abstract
PROBLEM TO BE SOLVED: To protect a human body and an equipment from being damaged by an electromagnetic wave. SOLUTION: Foamed polyurethane 1 impregnated with Bincho-Tan (special Japanese charcoal) powder is used in the present invention. It is known that foamed polyurethane impregnated with Bincho-Tan powder has an electromagnetic wave absorbing action, the absorbing effect is enhanced by impregnating pulverised Bincho-Tan powder into polyurethane, and easy application is allowed in a wide range of use.

出来るようにしたDETAILED DESCRIPTION OF THE INVENTION The present invention absorbs electromagnetic waves generated by foamed urethane impregnated with Bincho charcoal powder and protects the human body and other equipment from electromagnetic wave damage. Conventionally, electromagnetic waves have a negative effect on other electrical equipment and human bodies. It is well known that it is strongly required to shield this, but the present invention, which is in the process of research, has been made to meet this demand, and as described by the drawings, 1 is Bincho charcoal powder. It is said that the impregnated urethane bincho charcoal has an electromagnetic wave absorption effect, and the bincho charcoal is made into a powder to impregnate the foamed urethane to increase the absorption effect and make it easy to use over a wide range.
