CONSTITUTION:Carbon fiber reinforced carbon material, titanium, alumina or the like excellent in strength and bioaffinity is used as a base material, and a calcium phosphate compound is applied to the surface thereof, together with a biodegradable binder polymer, thereby providing a desired artificial filling and suturing material. As the calcium phosphate compound, calcium phosphate, hydroxyapatite or a mixture thereof is preferably used, from a viewpoint of a strong bone growth induction effect. Also, polyhydroxy-butylate, polylactic acid or the like is preferably used as the biodegradable binder polymer, and the dose thereof is 2 to 50wt.% or preferably 5 to 30wt.% of the calcium phosphate compound.

摘要： PURPOSE:To facilitate a treatment and to allow the artificial tooth root material to function in an early period after the treatment by constituting the part of the material in contact with the osteostructure of a threaded structure and a porous structure layer. CONSTITUTION:The artificial tooth root material has the porous structure layer in a part on the surface of a core material. The porous structure layer has >=10% porosity (voids) and is constituted of vapor phase pyrolysis carbon. The thickness thereof is >=0.1mm and the pore size of the surface is >=100mum. This layer is so constituted that the pore size diminishes from the surface part toward the core material side. The core material is a conductive material consisting of carbon or metallic material and is formed with the threaded structure. The biotissue infilters the pores of the porous structure layer when the artificial tooth root material is subjected to an initial fixing after embedment by the threaded structure part. Further, the infiltered connective tissue is calcificated and is changed to the osteostructure by the stereoscopic structure of the pores and the osteoinduction effect of the carbon. The artificial tooth root material is, therefore, securely combined and fixed to the living body.

摘要： PURPOSE:To obtain the title precursor which has a high carbonization yield and a low shrinkage factor during carbonization and allows graphatization to be freely controlled, by hydrogenating pitch to lower its softening point, adding a specified crosslinking agent thereto and heating the mixture in the presence of an acid catalyst. CONSTITUTION:At least one pitch having a solftening point of not lower than 120 deg.C selected from the group consisting of petroleum and coal pitches is hydrogenated to lower the softening point. A crosslinking agent mainly composed of an arom. compd. having at least two hydroxymethyl and/or halomethyl groups is added thereto. The mixture is heated in the presence of an acid catalyst at 60-300 deg.C to obtain the desired carbon precursor. The pitch used has a carbonization yield of not lower than 50wt%. It is desirable that the pitch having a low softening point and a high carbonization yield is used as a starting material. It is preferred that the hydrogenation is carried out by a direct hydrogenation method wherein the hydrogenation is carried out in the presence of a catalyst in a hydrogen stream at a high temp. under a high pressure.

摘要： PURPOSE:To make a size large by bonding porous electrodes on both side surfaces of a separator comprising a cured body of conductive thermosetting resin by using thermosetting resin as a binder, and unifying them by thermosetting. CONSTITUTION:A cured body of thermosetting resin having high chemical resistance, impermeability, and conductivity after setting is used as a separator. The separator is bonded to porous carbon or graphite electrode by using which is a binder the same thermosetting resin as the cured body and they are cured. Thereby, a composite electrode for fuel cell having many excellent performances in heat resistance, dimensional stability, strength, elastic modulus, toughness, water resistance, chemical resistance, and conductivity in the cured state without carbinization can be obtained, In addition, its size and shape can freely be controlled.

摘要： PURPOSE:To obtain the titled adhesive which gives a bonded structure having excellent heat resistance, water resistance, and bond strength, by reacting and heat curing either a mixture of a condensed polycyclic aromatic compound, an aromatic crosslinking agent, and an acid catalyst, or a thermosetting reaction intermediate thereof. CONSTITUTION:The titled adhesive is obtained by mixing the following com ponents. A: either a mixture of one or more of naphthalene, anthracene, pyrene, naphthacene, acenaphthylene, perylene, etc. and derivatives consisting principally of a skeleton thereof, or a condensed polycyclic aromatic compound having at least two rings, such as a heavy oil or pitch of, e.g., petroleum base or coal base. B: an aromatic crosslinking agent consisting of one or more aromatic rings having two or more hydroxymethyl groups and/or halomethyl groups. C: an acid catalyst comprising a mixture of one or more compounds selected from AlCl3, BF3, sulfuric acid, phosphoric acid, organic sulfonic acids, carboxylic acids and their derivatives. The molar ratio of B to A is 0.5-4.0, and the amount of component C is 0.5-10wt% based on A+B. If necessary, a thermosetting reaction intermediate obtained by reacting this mixture at 60-300 deg.C is made to react and heat cure.

摘要： PURPOSE:To obtain inexpensively the subject resin excellent in heat resistance and moldability by reacting a component based on fused polycyclic aromatic hydrocarbons successively with paraformaldehyde and a specified aromatic compound in the presence of an acid catalyst. CONSTITUTION:A polycyclic aromatic compound based on fused polycyclic aromatic hydrocarbons (e.g. naphthalene and anthracene) is reacted with paraformaldehyde in the presence of an acid catalyst (e.g. p-toluenesulfonic acid). An aromatic compound having at least two hydroxymethyls or halomethyls (e.g. dihydroxymethylbenzene or dichloromethylbenzene) is added to the reaction system and reacted in the presence of an acid catalyst to obtain a thermosetting hydrocarbon resin. Because the aromatic compound crosslinking agent and paraformaldehyde are used as the crosslinking agents, the amount of the expensive aromatic compound crosslinking agent used can be reduced.
