A node of a C company verifies transaction data received from a node of a B company, the transaction data proposing addition of a subject substance to a restriction list. When the node of the C company determines that information indicating that a new proposed subject substance falls under a restricted substance is incorrect by obtaining data on the restricted substance, for example, from the outside (a server apparatus or the like in an external group) and checking whether or not the subject substance falls under the restricted substance, the node of the C company does not approve the proposal for addition of the new subject substance to the restriction list but transmits transaction data that denies the proposal to the node of the B company (an arrow B).

A method is presented for effectively manufacturing multi-wall (double-wall, etc.) carbon nanotubes (CNTs) having a structure whereby interior tubes are formed within the CNTs. In this manufacturing method, fullerene/CNT hybrid structures are prepared, wherein assembled fullerenes, these being fullerenes that are linked, have been housed within single-wall CNTs. The interior tubes are formed from the assembled fullerenes by subjecting the hybrid structures to electron beam irradiation while in a heated state. It is preferred that irradiation with the electron beams occurs at a temperature of 100&#x2dc;500&#xb0; C. and with the electron beams having an accelerating voltage of 80&#x2dc;250 kV. According to the manufacturing method of the present invention, multi-wall CNTs with few defects can be manufactured at lower temperatures and in a shorter period than in the case where the fullerene/CNT hybrid structures are only maintained under high temperature conditions (and electron beam irradiation is not performed).

The gas storage method comprises a step of keeping a gas to be stored and an adsorbent in a vessel at a low temperature below the liquefaction temperature of the gas to be stored so that the gas to be stored is adsorbed onto the adsorbent in a liquefied state, a step of introducing into the vessel kept at the low temperature a gaseous or liquid medium with a freezing temperature that is higher than the above-mentioned liquefaction temperature of the gas to be stored, for freezing of the medium, so that the gas to be stored which has been adsorbed onto the adsorbent in a liquefied state is encapsulated by the medium which has been frozen, and a step of keeping the vessel at a temperature higher than the liquefaction temperature and below the freezing temperature.

A mechanical safety breaker for disengaging a mechanical connection between two mechanical members at a time when a force transmitted through the connection of the two members exceeds a predetermined value is provided by employing an overload breaker element made of a ceramic. A ceramic breaker element provides a long time stabilized fracture performance particularly when the load applied thereto is of a repetitive nature.

According to the method of the present invention, NO (nitrogen monoxide) in the exhaust gas of a diesel engine is first oxidized to NO.sub.2 (nitrogen dioxide) by an oxidizing catalyst. Further, carbon particles in the exhaust gas are trapped by a DPF (diesel particulate filter). The exhaust gas containing NO.sub.2 formed by oxidation of nitrogen monoxide is, then, fed to the DPF, and NO.sub.2 in the exhaust gas reacts with the carbon particles trapped in the DPF. When the NO.sub.2 reacts with carbon particles, carbon particles are oxidized (burned) by NO.sub.2 and removed from DPF, and, at the same time, NO.sub.2 is reduced to NO by the carbon particles. The exhaust gas containing NO formed by the reaction between the carbon particles and NO.sub.2 is fed to an NO.sub.X absorbent. In the NO.sub.X absorbent, NO is absorbed by the NO.sub.X absorbent and, thereby, removed from the exhaust gas. Therefore, according this method, the carbon particles collected by the DPF can be easily burned by NO.sub.2, thereby being removed from the DPF without increasing the amount of NO released to the atmosphere.
