    Abstract: When finely divided SHIRASU (pumice ejected from volcanoes and the secondary deposit of such pumice) is roasted at a temperature in the range of from about 800* to about 1200*C, the vitreous particles contained in said SHIRASU foam and consequently produce light-weight hollow glass microspheres. The hollow glass microspheres so produced are superior to conventional glass microspheres especially in their resistance to heat and can therefore be combined with metal, carbon, as well as with cement and other materials to produce novel lightweight composites.

    Abstract translation: 当分散的SHIRASU（从火山喷出的浮石和这种浮石的二次沉积物）在约800℃至约1200℃的温度范围内焙烧时，所述SHIRASU泡沫中包含的玻璃质颗粒因此产生轻质 中空玻璃微球。 如此制造的中空玻璃微球优于传统的玻璃微球，特别是在耐热性方面，因此可以与金属，碳，以及与水泥和其他材料结合，以生产新颖的轻质复合材料。

    Abstract: The invention provides carbon fibers having mechanical properties equivalent to or even better than those of the polyacrylonitrile-based carbon fibers from a bituminous material, e.g. coal tar pitch, as the starting material. The starting pitch is first partially hydrogenated in tetrahydroquinoline under specific conditions followed by a heat treatment to give a pitch composition suitable for spinning which can be characterized by several parameters including the proportions of the carbons and hydrogens having different chemical shifts in the NMR analysis. The pitch composition for spinning is then subjected to spinning under specific conditions including the temperature condition for controlling the viscosity behavior of the molten pitch composition determined by use of the Andrade's equation and the pitch filament is then infusibilized in an oxidative atmosphere and carbonized in an inert atmosphere into carbon fibers having a tensile strength of at least 200 kg/mm2 and a tensile modulus of at least 10 tons/mm2.

    Abstract: A process for the production of shaped articles of high density graphite having excellent mold-releasing property which comprises incorporating amorphous carbon powder such as powdery coke or artificial graphite powder with about 3-20% by weight of boric acid or boron oxide as a sintering-promoting agent, and baking the mixture under a pressure of 150-500 kg/cm2 without the aid of a binding agent such as pitch. Shaped articles of high density graphite possessing excellent mechanical strength are obtained by this process.

    Abstract: PROCESS FOR THE PRODUCTION OF ASHLESS LIQUID FUELS An ashless liquid fuel of good quality is produced by combining powdery coal with a heavy oil of the petroleum series in an amount of at least 50 parts by weight of heavy oil per 100 parts by weight of the powdery coal, subjecting the mixture to a heat treatment conducted at 400-450.degree.C and thereafter, removing a solid coagualted material formed in the treated product. An especially good result is obtained when a heavy oil of petroleum series having an atomic ratio C/H of at least 0.9 is used.
