摘要： A method of fabricating an eraser which contains a main basic material of low crystallizable polyolefin thermoplastic elastomer and normal synthetic rubbers having no hard segment for performing a crosslinking effect, namely, any one or more of chlorinated polyethylene, ethylene-propylene terpolymer, ethylene ethyl acrylate, ethylene-vinyl acetate copolymer, atactic polypropylene, styrene-butadiene rubber, nitrile rubber and the like. The thermoplastic elastomer exhibits similar properties to vulcanized rubber without particular vulcanizing operation and crosslinking reaction. In case that less than 40 parts by weight of the elastomer is contained in the eraser, the composition does not form an eraser, while in case that higher than 100 parts by weight of the elastomer is contained in the eraser, the composition incorporates excessive rubber-like properties. The method comprises the steps of mixing and kneading 50 to 800 parts by weight of factice, 0 to 500 parts by weight of filler and predetermined amount of pigment which 40 to 100 parts by weight of the low crystallizable polyolefin thermoplastic elastomer. Thus, the eraser is remarkably improved in the properties such as resistances to deterioration by aging, exposure to sunlight, migration of plasticizer, and tearing strength by its metallic band.

摘要： Porous materials of carbon can be manufactured by introducing particles of organic polymer in a vessel of an arbitrary shape, dissolving a particle surface layer to produce point bondings between the particles, thereby producing porous materials of organic polymer, then insolubilizng or infusibilizing it, and further calcining the particles in inert gas atmosphere, thereby obtaining the porous materials of carbon fundamentally as sintered particle materials. Thus, this process permits, essentially without difficult means of managing complicated steps such as impregnating or extracting, facilitated manufacture of porous materials of carbon having a large quantity of continuous pores with ready adjustments of porosity and diameters of the pores and high strength.

摘要： A process for producing a carbon heat generator is disclosed including the steps of uniformly dispersing one or more types of metal compounds capable of forming a vitreous film upon oxidation in a moldable composition, molding the resultant dispersed composition, precarbonizing the molded composition, and then carbonizing the composition in a nonoxidative atmosphere to form a carbon heat generator having an oxidation preventive glass film. The oxidation of the metal compound exposed on the surface of the molded composition by the use of an oxidative atmosphere forms a vitreous film which prevents oxygen from diffusing in the interior thereof. The film so produced can form a new glass film on a damaged portion by a self-recovery effect if a pinhole or a crack occurs in the glass film. Thus, the process does not cause external appearance and weight differences before and after heat generating.

摘要： A working micro-electrode with a reference electrode prepared by coating a working micro-electrode with an insulating material except a working electrode portion, forming a silver layer on the coated surface, and then changing a portion of the silver layer into silver chloride which is the reference electrode; a working micro-electrode with a reference electrode and a counter electrode prepared by coating the working micro-electrode with the reference electrode with an insulating material, and then forming the counter electrode on the surface of the insulating material; and methods for preparing these composite micro-electrodes.Heretofore, even if the working electrode is thinly constituted, the merit of the micro-electrode has not been sufficiently utilized, since the reference electrode and the counter electrode have been thick. However, the present invention can solve this problem and can facilitate experiments in which the micro-electrode is necessary.Since an inexpensive material such as carbon can be used, the working electrode may be constituted so as to be disposable or can be cut off the used portion to repeatedly obtain a new electrode surface. Therefore, the working electrode of the present invention is economical.

摘要： A carbon micro-sensor electrode is disclosed which is prepared by impregnating, adsorbing or chemically modifying a pure composite carbon wire having many micropores extending to its surface and interior with a reactant such as an enzyme, a metal complex compound, an organic compound or a metabolite; and a method for preparing this carbon micro-sensor electrode is also disclosed.The above-mentioned electrode can be used for a long period of time, since the reactant is received in the many micropores. Furthermore, after used, the electrode may be cut off to expose a new electrode surface, and this new electrode surface may be coated with a material which does not impede an electrode reaction, whereby the reactant can be prevented from flowing out. Thus, the carbon micro-sensor electrode of the present invention can be repeatedly utilized.

摘要： An inplant material for a living body hard tissue which is constructed by forming a core of a carbon material having a smooth and high hardness surface, an excellent mechanical strength against bending and compressing strengths, and non-impregnable to blood, lymph or the like and further forming a porous layer having a thickness of 100 microns or larger, preferably 100 microns or large on the surface of the core. This porous structure of the implant material is very important to smoothly and rigidly bond the material to a living body and is devised to produce the state that a collagen fiber newly produced in the boundary between the living body and the implant material is intruded into the porous tissue of the surface of the implant material and mutually interchanged, and a process for producing the same. Thus, the implant material has a smooth and high hardness surface, an excellent mechanical strength against bending and compressing strengths, and being non-impregnable to blood, lymph or the like.
