摘要： The present invention relates to an apparatus for continuous-direct-resistance heating of long-length articles wherein the travelling long-length article is made to contact with roll electrodes disposed in a specified spacing, then made to pass through an annular transformer disposed between the roll electrodes.Conductive members with sufficiently less electrical resistance than that of the long-length article located between the both electrodes are disposed on the periphery of the transformer with the both ends thereof connected to the roll electrode through a slider, thereby a current being induced in the long-length article with the conductive member as the retrace, which heats the long-length article having a higher resistance very efficiently, neither resulting in an external voltage, nor causing electrically any obstacle to the production line in which the apparatus is installed.The apparatus comprises three roll electrodes, two transformers and conductive members being disposed on the periphery of the transformer connected to the neighboring roll electrode, the power being fed to each transformer from two single-phase transformers in the Scott connection with a three-phase power supply, thus providing heating without developing imbalance in the three-phase voltage.

摘要： In preparing superfine particle in a reaction chamber by evaporation-in-gas method or on such processes as PVD or CVD using arc- or high-frequency plasma wherein in the proximity of the inner surface of the said reaction chamber, a vessel provided with a number of pores thereon is arranged and gas consisting of given components is introduced into the space between the inner surface of the chamber and the vessel, and spouted through the said pores on the vessel. The resultant superfine particle produced in the chamber and being in Brownian movement or in thermal migration does not adhere to the surface of the vessel by being separated from the vessel by the spouting gas so that the gas containing superfine particle is directed securely to the collecting path, wherein the vessel is made of the material not reactive with the resultant superfines but resistant to heat.

摘要： The present invention is drawn to a method and apparatus for holding wire at a specified temperature for a specified period of time by a direct-resistance heating device which applies such voltage as to generate Joule's heat in the wire, sufficient to offset the quantity of heat that would tend to be released from the heated wire during unforced cooling, after the travelling wire is heated rapidly to a specified temperature throughout its cross section. A temperature-holding apparatus, employed subsequent to the heating of wire, may either supply power directly to a wire through feeding wheel electrodes or entail a combination of a shell type transformer and a hollow annular holding furnace incorporating guide rollers, and having wheel electrodes electrically connected by a lead, disposed outside of the inlet and outlet of the holding furnace incorporating guide rollers, and producing secondary current in the multiple-wound wire in the furnace with the lead as a return, depending upon the holding time desired. The latter form of the apparatus imparts an advancing force and curl to the wire so that thick and inflexible wire can be placed in the holding furnace, and rollers are provided to create a desired number of turns in the wire in the holding furnace.
