Inventor: TAKANASHI SATOSHI
IPC: G03G15/20
Filed: 1995-06-14
Abstract: PURPOSE: To prevent a deterioration in image quality by providing a regulating member for regulating foreign matter after slipping through a cleaning member not to enter the contact part of an oil coating roller. CONSTITUTION: This fixing device is provided with a heat resistant film 13 as the regulating member regulating the foreign matter of particulates after slipping through not to enter the contact part of the oil coating roller 10 with a cleaning roller 11, on the downstream side from a blade 12 in the rotational direction of the cleaning roller 11. At this time, the heat resistant film 13 is pressedly attached to an oil coating unit, etc., so as to come into surface contact with the cleaning roller 11 by the self elastic force of the film 13. Thus, the foreign matter of the particulates after slipping through the blade 12 is dammed up at the contact position of the cleaning roller 11 with the heat resistant film 13.  Therefore, the foreign matter of the particulates is retained/solidified on the oil coating roller 10, without reaching the side of the roller 10, to prevent a failure such as the deterioration in the image quality caused by the sticking of the foreign matter to a transfer material due to the retransfer of the foreign matter to a fixing roller.

Title: Preventing method for dew condensation in heat treatment of aluminum slab
Inventor: KUROSAWA YOSHINORI
IPC: C22F1/04
Filed: 1981-09-18
Abstract: PURPOSE:To prevent dew condensation on the surface of an Al slab by coating the slab with a liq. which is not burned off by heating up to about 100 deg.C and is burned off by heating to >= about 100 deg.C and by heating the coated slab in a heating furnace. CONSTITUTION:When an Al slab is planed, charged into a heating furnace, and homogenized or soaked before carrying out hot rolling, the slab is coated with a liq. which is not burned off by heating up to about 100 deg.C in the furnace and is burned off by heating to >= about 100 deg.C. The liq. is a soln. of acrylic resin or epoxy resin, rust preventing oil, silicone oil, glycerol or the like. Thus, even if the slab is heated to about 500-600 deg.C, the deterioration of the quality due to dew condensation can be prevented because the state with the formed coat on the planed surface of the slab is maintained until the slab reaches a temp. at which dew condensation is caused.
