Title: Scum deposition preventing method
Inventor: OHASHI HIDEMI
IPC: C23G1/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent the deposition of scum on the inner wall of a tank by introducing silicone oil into a cleaning tank in a steel sheet cleaning stage. SOLUTION: A steel sheet is cleaned with an alkali cleaning soln. in a continuous steel sheet cleaning line. The contaminant component of the rolling oil, rust inhibiting oil, etc., is removed from the steel sheet surface by cleaning and saponified to form sodium soap. As the accumulation of the soap is increased, iron powder, etc., are mixed in the soap to form a scum, and the scum is stuck to the inner wall of a tank. The surface tension of the cleaning soln. is lowered by injecting silicone oil. As a result, even the cleaning soln. depositing on the tank wall face is easily dripped and returned to the soln. in the tank, the deposit is eliminated, and the scum is not accumulated. An organopolysiloxane having 10-1,000,000cst viscosity (at 25 deg.C) is preferably used as the silicone oil.  The emulsion of the silicone oil is diluted with water to control the Si concn. to 0.01-25wt.% and supplied to the tank.

Abstract: PURPOSE:To improve safety by stopping the operation of a washing tub when the operation of the washing tub is detected, the cover opened state is detected, and no cover opening instruction is inputted. CONSTITUTION:When a power switch is judged as on and upper cover switches 418, 425 are judged as off based on the detected result of an upper cover opening detecting circuit 119, i.e., when an upper cover is opened, whether a cover opening key is operated or not is judged.

When a drum is judged to be rotating, i.e., a washing machine is operated, the drum is forcefully stopped. When the upper cover is opened by the noise entering from an ambient apparatus via the AC power source 300 during the operation of the washing machine, the drum is immediately stopped, and the safety during the high-speed rotation of the drum is secured.
