    摘要： Graphitized carbon powder are produced by carbonizing and expanding a pitch by heating to form carbonaceous foam and by graphitizing before pulverizing or graphitizing after pulverizing the carbonaceous foam. The resultant graphitized carbon powders have an interplanar spacing (d002) of graphite planes of less than 0.3370 nm. The powders preferably have an average particle size of from 2 to 200 &mgr;m. A thermally conductive composition includes the graphitized carbon powders in a matrix. The content of the powders is preferably 1 to 800 parts by weight relative to 100 parts by weight of the matrix. Thus, the graphitized carbon powders that have excellent thermal conductivity and a thermally conductive composition including such powders are provided.

    摘要： A thermally conductive molded article is produced by molding a conductive composition into a predetermined shape. The composition includes a polymer matrix and carbon powders. The carbon powders are obtained by graphitizing a polymeric material that has an aromatic ring on its main chain by heating. The carbon powders are aligned in a certain direction in the polymer matrix. Thus, the molded article can be produced easily and effectively that has excellent thermal conductivity in a given direction and that is suitable for use as a heat radiator, heat transfer member, or a component thereof in electronic hardware.

    摘要： A method of manufacturing a heat conductive molded part having determined heat conductivity properties is provided. The method includes providing a polymer composition containing boron nitride powder. A magnetic field is impressed to the polymer composition containing boron nitride powder, field orienting the boron nitride powder in the polymer composition to a fixed direction. The polymer composition is set containing boron nitride powder with the boron nitride powder oriented in the polymer composition to the fixed direction. The polymer composition may also be provided containing a solvent. The solvent is removed after field orienting the boron nitride powder in the polymer composition to the fixed direction The composition is then set with the field oriented boron nitride powder after having removed the solvent.

    摘要： Disclosed is a thin key sheet in which the adhesive is prevented from being squeezed out and in which adhesive marks and bubble marks are hard to be visible. An adhesive layer is in a dot pattern formed by a plurality of dots spaced apart from each other by gaps, so when attaching a key top and a base sheet to each other through an intermediation of the adhesive layer, it is possible to allow air to escape through the gaps, and bubbles recognizable to a naked eye are not easily trapped by the interior of the adhesion layer or an interface between the adhesive layer and the key top. Further, since the adhesive layer is a screen print layer, a dimension of elements of fine pattern thereof can be on an order of microns, thereby making the fine pattern of the adhesive layer hard to be visible through the key top.
