摘要： There is provided a method for producing a multijunction solar cell having four-junctions, the method allowing the area of a device to be increased. On a nucleation site formed on a substrate 2, is grown a semiconductor 2a comprising the same material as the substrate 2 in the shape of a wire. On the semiconductor 2a, are successively grown semiconductors 3, 4, 5, and 6 with a narrower band gap in the shape of a wire. The semiconductor 3 may be directly grown in the shape of a wire on the nucleation site formed on the substrate 2. It is preferred to form the nucleation site by forming an amorphous SiO2 coating 8a on the substrate 2 and etching a part of the amorphous SiO2 coating 8a. Further, it is preferred to form an insulating film 8 in the region except the nucleation sites on the substrate 2 by allowing the amorphous SiO2 coating 8a to remain therein. The semiconductor 2a is GaP; the semiconductor 3 is Al0.3Ga0.7As; the semiconductor 4 is GaAs; the semiconductor 5 is In0.3Ga0.7As; and the semiconductor 6 is In0.6Ga0.4As.

摘要： A hydrogen storage tank comprises a hydrogen adsorbent accommodated in a pressure-resistant container. The hydrogen adsorbent is capable of adsorbing and retaining hydrogen gas of a volume exceeding an occupation volume occupied by the hydrogen adsorbent itself. As for the hydrogen adsorbent, the amount of endothermic heat, which is generated when the adsorbed hydrogen gas is released, is not more than 16 kJ per mol of hydrogen molecules. The hydrogen adsorbent is prevented from leaking outside of the pressure-resistant container by a filter.

摘要： Carbon structures, e.g. carbon nano-fibers, suitable for absorbing hydrogen at low pressures and low temperatures are produced by a selective oxidation and/or acid reflux process. The process includes heating an impure mixture containing a crystalline form of carbon in the presence of an oxidizing gas at a temperature and time sufficient to selectively oxidize and remove a substantial amount of any amorphous carbon impurities from the mixture. Metal containing impurities can be removed from the mixture by exposing the desired carbon and accompanying impurities to an acid to produce a carbon fiber that is substantially free of both non-fiber carbon impurities and metal impurities. Another aspect of the present invention includes purified carbon structures that can store hydrogen at low pressures and temperatures.

摘要： To produce a hydrogen absorbing alloy powder which is an aggregate of alloy particles each including a metal matrix and added-components, an aggregate of metal matrix particles and an aggregate of added-component particles are used, and mechanical alloying is carried out. In this case, the relationship between the particle size D of the metal matrix particles and the particle size d of the added-component particles is set at d≦D/6. Thus, the milling time can be shortened remarkably.

摘要： A gas cooking stove is disclosed to which a very-small gas cylinder is joined in a one-touch manner and the state of joining is reliably maintained. When the gas cooking stove is used, the gas cooking stove can stably be installed. When the gas cooking stove is not used, the overall size can be reduced to save the space. Thus, the operability, safety and the portability can be improved. A valve mechanism, an operation member for opening/closing the valve mechanism and a piezoelectric spark unit are provided. Moreover, a stove body is provided which has an upper portion to which a dish is joined and a lower portion provided with a gas-cylinder joining portion to which a gas cylinder is joined. A grate is rotatively supported by the dish. The gas cylinder having a valve-joining cylindrical portion which is integrally formed with the gas cylinder, which accommodates a valve mechanism, in which the valve mechanism is secured and from which a stem is allowed to project over the valve-joining cylindrical portion is joined to the gas-cylinder joining portion in the one-touch manner. The gas cylinder has the valve-joining cylindrical portion which is held by a cylinder holding member.
