摘要： PROBLEM TO BE SOLVED: To provide a radio wave absorbent which is enhanced in radio wave absorption characteristic and practical serviceability by a method wherein the radio wave absorber composed of a nonwoven fabric formed of a first fiber coated with a metal oxide and a second insulating fiber fiber not coated with a metal. SOLUTION: A radio wave absorber is a nonwoven fabric formed of a first fiber and a second fiber. The first fiber is coated with a metal whose surface is oxidized, and the second fiber is not coated with a metal and good in insulating properties. The metal-coated fiber and the insulating fiber are mixed together at a prescribed ratio, formed into a nonwoven fabric, and then subjected to an oxidation treatment to convert the surface of the metal of the metal-coated fiber into an oxide. Or, the metal-coated fiber whose surface coating metal is oxidized by an oxidation treatment and the insulating fiber are mixed together at a prescribed ratio and formed into a nonwoven fabric. With this setup, a radio wave absorber enhanced in radio wave absorbing property and practical properties such as processability, reduction in weight and cost, and others.

摘要： PURPOSE: To provide a radio wave absorber, which is superior in radio wave absorption and practicability. CONSTITUTION: A radio absorber consists of an unwoven fabric made of first fibers, which are covered with silver and at the same time, is subjected to sulfurization treatment on said silver, and second insulative fibers, which are not covered with a metal. Accordingly, the surface of the silver-covered fibers, which are used as conductive fibers, is subjected to sulfurization treatment, whereby the resistance of the conductive fibers can be made high. Thereby, the radio wave absorption performance of the radio wave absorber is enhanced and the absorbable frequency band of the radio wave absorber can be made wide.

摘要： PURPOSE:To obtain a magnetic shield material wherein the mutual contact of magnetic shield powder is not hindered by resin or an adhesive and which is excellent in a magnetic shield effect, by a method wherein bases each having a powder layer formed by sticking the magnetic shield powder uniformly on the surface are laminated with the powder layers opposed to each other, without interposing the adhesive. CONSTITUTION:A base laminate 20 is formed of a pair of sheet-shaped bases 10 laminated on each other. An adhesive 11 is applied thinly on the surface of each sheet-shaped base 10 and magnetic shield powder 12 is dispersed uniformly with the adhesive 11 interlaid and sticks on the surface of the base, in mutual contact, so that a magnetic shield powder layer be formed. The sheet-shaped bases 10 are laminated with the magnetic shield powder layers opposed to each other. Neither the adhesive nor resin is interposed between the powder layer of one base and the powder layer of the other and the magnetic shield powder is brought into the mutual contact directly. Besides, another magnetic shield powder layer 13 not having the adhesive is interlaid between the opposed powder layers. Therefore the mutual contact of the magnetic shield powder is obtained and thus a high magnetic shield effect is produced.

摘要： PURPOSE:To enhance a magnetic shielding effect by kneading and dispersing flakelike powder having a function of magnetically shielding in medium such as resin, etc. CONSTITUTION:Powder having a function of magnetic shielding may generally be, if it has flakelike state, powder of a soft magnetic material or preferably of sendust alloy, permalloy alloy or amorphous alloy of them. The magnetic powder becoming the flakelike state is, for example, uniformly kneaded and dispersed in thermoplastic resin such as polyvinyl chloride resin, etc., by using a roll mill, etc. Then, this kneaded material is cooled to obtain a magnetic shielding material. Thus, a magnetism can be shielded with a single member having a platelike or predetermined shape by altering its thickness in response to an intensity of the magnetism to be shielded.
