Title: Method for reducing static electricity in bright annealing furnace for stainless steel
Inventor: HAGIWARA TOSHIYA
IPC: C21D9/56
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of ignition in a sealing part by controlling the electrolytic conditions in electrolytic equipment so that the difference between the electrification potential of a steel strip in a furnace sealing part and the electrification potential of a sealant can be reduced. SOLUTION: Static electricity, caused by pushing and separation against and from a continuous steel strip 4 and friction, is generated at the surface of a roll and a sealant of a sealing device 3C of a bright annealing furnace 3. At this time, the sealant and the stainless steel strip 4 are respectively electrified, and an electrostatic energy is increased with the increase of the difference between the electrification potentials of both, and the gas leaking from the sealing device 3C becomes liable to ignite. Therefore, electrolytic conditions in electrolytic equipment 2 are set so that the electrification potential of the steel strip 4 approaches that of the sealant. As to electrolytic conditions, it is preferable to change current density, quantity of electricity, or electrolytic direction. Further, it is preferable to set so that the electrification comes on the plus side.  Further, nylon is preferred as the sealant.

IPC: G03G21/00
Filed: 1989-12-29
Abstract: PURPOSE:To ensure the loading of a single original by providing a stop member which abuts, from the downstream side in the displacement direction, on a single-original holding member. CONSTITUTION:The holding member 102, on which the single original 103 is loaded, is slidably loaded to a guide member 210 extending across a previously determined optical path. The member is designed in such a manner that the member can cross the optical path while holding the single original 103, and that the member 102 can be displaced between the displacement start position l1 and the displacement end position l2. In addition, the holding device is constituted in such a manner that when the single original 103 is loaded, in the displacement start position l1, on the holding member 102, the stop member 99 abuts, in the displacement start position l1 and from the downstream side in the displacement direction, on the holding member 102. Therefore, the slide holder 96 is prevented from being pushed down by the force of an operator when the slide film 103 is loaded. Thus, the loading of the slide film 103 can be ensured.
