    摘要: An abrasive wire provides an efficient cutting operation with high accuracy and a longer service life. Abrasive grains are provided around a core wire. The abrasive grains are bonded to the core wire by a light curing resin or an electron beam curing resin which can be cured within a few seconds. Accordingly, the curing operation can be performed while the core wire is moved in the direction of the longitudinal axis of the core wire. Thus, a long abrasive wire can be fabricated at reduced time and cost.

    摘要: The present invention provides a hydrogen production method capable of producing hydrogen with good efficiency while solving problems such as separation, lower-temperature reaction and heat supply in production of hydrogen by dehydrogenation reaction of raw material oil. Within a reaction tube of a double-tube structure comprising an inner tube composed of a hydrogen separating membrane, a metallic outer tube having a plurality of internal fins, and a metal oxide layer and further a catalyst supported on the fins, hydrocarbon having cyclohexane ring is dehydrogenated to produce hydrogen and aromatic hydrocarbon, and selective membrane separating operation of hydrogen is performed within the reaction system while conducting the dehydrogenation to remove mainly the hydrogen on a permeating side and obtain mainly the aromatic hydrocarbon on a non-permeating side. The other method comprises absorbing at least part of the resulting hydrogen flow to a hydrogen absorbing (storing) alloy to make the pressure on the hydrogen permeating side of the hydrogen separating membrane lower than that on the non-permeating side.
