    Abstract: PROBLEM TO BE SOLVED: To provide a simply constituted and compact hydrogen production apparatus.
    SOLUTION: The apparatus is equipped with a compression chamber for a reactor 1 for holding the mixture of reactive particles and steam for shock compression. a feeder 14 which feeds the reactive particles to the compression chamber, an intermittent injection pump 5 which is connected with a steam well from which geothermally generated high pressure steam is taken out and intermittently feeds the high pressure steam to the compression chamber. The intermittent supply of the high pressure steam to the compression chamber with the intermittent injection pump 5 generates shock waves. The shock waves spread in the chamber and shock-compress the mixture in it. The mixture is heated to high temperatures, which causes the reactive particles in the mixture to react with the steam. A hydrogen-containing gas is generated.

    Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen production apparatus that has a simple constitution and is compact in size. SOLUTION: The hydrogen production apparatus has a compression chamber of a reaction apparatus 1 in which the mixture of reactive particles and steam is contained and subjected to shock compression, a vacuum pump 13 which depressurizes the compression chamber, a feeder 17 which feeds the reactive particles and an intermittent injection pump 5 which generates shock waves by intermittently feeding the high pressure steam to the compression chamber. The intermittent injection pump 5 instantaneously feeds the high pressure steam to the compression chamber, when the chamber is depressurized by means of the vacuum pump 13. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing hydrogen whereby hydrogen is manufactured with reduced energy loss at a low operation cost and equipment cost, small-scaled production is performed and hydrogen is produced while suppressing the discharge of carbon dioxide without necessitating pure fuel. SOLUTION: The apparatus is provided with a compression chamber of a reactor 1 wherein a mixture of waste plastic powder with steam is housed to give impulse and compression to heat to a high temperature and a impulse wave generation apparatus 3 for generating impulse wave to give the impulse and compression to the mixture in the compression chamber. The waste plastic powder and the steam are reacted with each other to produce a hydrogen- containing gas by propagating the impulse wave generated by the jetting of high pressure steam in a waste heat boiler 3a in the impulse wave generation apparatus 3 to the compression chamber to give the impulse and compression heating to the high temperature.

    Abstract: A cubic boron nitride cluster comprises a core ( 10 ) and an overgrown region, the overgrown region containing a plurality of cubic boron nitride crystallites ( 12 ) extending outwards from the core ( 10 ). The majority of the cubic boron nitride crystallites ( 12 ) have a cross-sectional area which increases as the distance from the core ( 10 ) increases. A method of producing cubic boron nitride clusters is also provided.

    Abstract: PURPOSE:To provide such material as dense dielectric/conductive composite material by executing quasi-adiabatic heating at an extremely high speed and making the material denser before a thermal equil. is attained between conductive, semiconductive and dielectric phases. CONSTITUTION:A powder mixture 11 contg. a low-electric resistance material and high-electric resistance material greatly varying in resistivity is put into a dielectric container 47 and one to plural pieces of pulse currents having required energy and short duration time are passed via a conductive route 49 to such powder mixture in the state of applying the prescribed pressure thereto by means of a stationary pressurizing structural body 40 and a moving pressurizing structural body 42. As a result, the powder mixture 11 is made denser and/or a phase change is generated in the powder mixture by selectively heating the low-electric resistance material. Consequently, such material as the dense dielectric/conductive composite material is obtd.
