A process is disclosed for culturing microorganisms or cells isolated from a multicellular organism while exposing the microorganism or cells to sound waves of 5 to 100 kHz. This procedure effects the proliferation and the expression of functions of the cells so exposed. An apparatus for culturing the cells according to this process is also disclosed.

Process for culturing microorganisms or cells using sound waves

The present invention provides a method for forming a novel carbonaceous material, which has properties such as acceptor properly useful as a secondary cell electrode material and a host material for catalyst, comprising of the steps of electrochemically polymerizing a nitrogen-containing organic compound as a monomer constituent, and heat-treating the resultant polymer as a carbon precursor.

Method for producing a nitrogen-atom containing carbonaceous material

An artificial filling and prosthetic material, characterized in that the surface of a substrate is coated with a calcium phosphate compound together with a water-insoluble and bio-degradable binder polymer. This material is capable of firmly adhering to tissue for a short time.

Artificial filling and prosthetic material

A dental implant comprising a core material and a porous layer formed on the core material, wherein at least a part of the core material coated by the porous layer has a non-circular cross-sectional shape so as not to rotate relative to the porous layer.

Dental implant

An adhesive made from a thermosetting resin composition consisting of (a) a condensed polycyclic aromatic compound, (b) an aromatic crosslinking agent and (c) an acid catalyst is applied to each surface of adherends treated with a particular surface treating agent and heated at a temperature of 100.degree.-400.degree. C. in an oxidizing or non-oxidizing atmosphere to produce an adhesion structure. In order to provide a conductive adhesion structure, a conductive promotion catalyst is included in the adhesive. Further, a carbonaceous or graphitic adhesion structure is obtained by carbonization or graphitization of the adhesion structure.

A condensed polycyclic, polynuclear aromatic thermosetting resin with improved moldability which is prevented from forming a cloud on a mold during molding is disclosed. The resin is a prepolymer derived by condensation polymerization of a condensed polycyclic aromatic compound or a mixture thereof with a monocyclic aromatic compounds and an aromatic compound having at least two hydroxymethyl groups as a crosslinking agent in the presence of an acid catalyst. The resin has a flow temperature of not higher than 150.degree. C. The acid catalyst is water-insoluble or when it is water-soluble the resin has an insolubilized acid ratio of at least 50%. The resin is useful in the manufacture of thermoset molded articles having good heat resistance and good mechanical and electrical properties. It can be blended with a filler and/or reinforcing agent to form a molding compound.

Process for the preparation of carbon fibers

A novel reformed mesophase pitch having a mesophase content MC of between 40 and 100%, a quinoline-insoluble content QI of between 5 and 70 weight % and anisotropic domains forming a continuous phase. The reformed mesophase pitch is obtained by heat-treating a dormant mesophase pitch which comprises dormant anisotropic components which are partially hydrogenated, polycyclic polycondensed ring aromatic hydrocarbons derived from the mesophase of a mesophase pitch by hydrogenation of the mesophase and which are soluble in quinoline. The dormant mesophase pitch is optically isotropic in nature but, upon being subjected to shear forces in one direction, capable of being oriented in said direction. Preferably, the reformed mesophase pitch has a softening point SP in .degree.C. satisfying the following conditions:

Carbonaceous pitch, process for the preparation thereof and use thereof

A novel carbonaceous pitch which is optically isotropic in nature and which turns into optically anisotropic when shear forces are applied thereto. The carbonaceous pitch may be obtained by hydrogenating the mesophase of a mesophase pitch to the extent that the mesophase is rendered soluble in quinoline. The carbonaceous pitch is useful as a binder and an impregnator and as a precursor material for a highly oriented, high-strength and high-modulus carbon fiber, needle coke or the like carbonaceous materials.
