Title: Large electric power ferrite for microwave
Inventor: KIKUCHI NORIMI
IPC: H01F1/36
Filed: 1981-05-09
Abstract: PURPOSE:To obtain a ferrite which reduce a microwave loss even at low electric power by producing a large electric power ferrite with Mn-Mg series spinel type ferrite baked powder having a true specific weight in the range of 3.90-4.05. CONSTITUTION:A raw material which contains by weight % 70% of Fe2O3, 8% of MnO and the residue of Mg is mixed with water in a ball mill, the obtained slurry is removed from the mill, and is dried. This slurry is then baked in an electric furnace, and is so adjusted that the true specific weight of the attained baked powder is in the range of 3.90-4.05. Subsequently, this slurry is again filled in the mill, is pulverized and dried together with water for 24hr, 5% of a binder of PVA is added as a solid content to the slurry, and the mixture is sufficiently stirred. Then, the mixture is filled in a mold, is pressed under the pressure of 1ton/cm<2> to form it in the prescribed shape, is then sintered at 1,200 deg.C, is further polished, and is associated in a circulator. Thus, a ferrite having low loss less than 0.3dB can be obtained even in a low electric power range.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain conductive porous bamboo charcoal chips of a hexagonal shape which are formed by baking up bamboo materials at a high temp. and are sufficiently subjected to soaking and are applicable to electromagnetic wave shielding materials, antistatic agents, etc., by slice molding the bamboo charcoal to a chip form, then subjecting the bamboo charcoal to surface treating. SOLUTION: Phyllostachys bambsoides Sieb. et Zucc., Phyllostachys pubescens Mazel, etc., are used for the carbonaceous materials of the bamboo charcoal, and are subjected to backing up at about 1,000 deg.C and are sufficiently subjected to soaking (scouring) and thereafter, the bamboo charcoal of the porous structure having the hexagonal shape is slice molded to the chip form to form small pieces of, for example, a disk shape, rectangular shape, etc., and is then subjected to the surface treating. As a result, the lightweight and conductive bamboo charcoal chip materials having the high stability are obtd. Electromagnetic waves are shielded and the generation of static electricity may be prevented simply by affixing the materials to various kinds of the apparatus products.  For example, the apparatus may be protected against the external electromagnetic waves by sticking the materials to the exterior parts of the computer apparatus, ceramic substrates, the bodies of automobiles, etc.
