Title: Shaking out method for precision casting
Inventor: IGARASHI SHIGERU
IPC: B22D29/00
Filed: 1988-05-20
Abstract: PURPOSE:To reduce the cost of shaking out by immersing a precision casting to which refractories are stuck into a soln. contg. hydrofluoric acid, thereby removing the refractories. CONSTITUTION:The soln. prepd. by adding nitric acid, etc., at 5-20wt.% or other ratios to the hydrofluoric acid is prepd. and the precision casting on which the refractories are stuck is immersed therein. The hydrofluoric acid generates pickling by forming pitting holes to the steel part of the precision casting and dissolves the casting mold at this time. An oxidation resistance suppressor such as nitric acid, however, suppresses the pickling. The drop of the casting mold refractories is extremely accelerated when the precision casting is oscillated. Since the need for using caustic soda which necessitates large electric power and much labor is thereby eliminated, the cost of the shaking out is reduced.

Title: Aging method of thermoplastic resin film-shaped foam
Inventor: KARASAWA MASATO
IPC: B29C48/32
Filed: 1984-06-15
Abstract: PURPOSE:To obtain an excellent re-expansion effect by winding a filmy foam on a core material in a comparatively large inner diameter, removing the core material and maturing the foam. CONSTITUTION:A thermoplastic resin film-shaped foam 11 molded by using a physical foaming agent is wound on a core material 6 in a comparatively large diameter. It is preferable that the inner diamter of winding extends over 300mm. or more. It is because there is no position of relief for the thermoplastic resin film-shaped foam 11 on aging and the magnification of expansion is inhibited when the inner diameter is less than 300mm.. The core material 6 for the wound thermoplastic resin film-shaped foam 11 is removed, and the foam is matured. The core material 6 can be removed easily because backing plates 3 are separated from the inner circumferential surface of the thermoplastic resin film- shaped foam 11 when screws 5 are loosened and arms 4 are retreated into a holding cylinder 2. 12hr or more, preferably, 20hr or more, at the normal temperature is desirable as the conditions of maturing. Accordingly, when the thermoplastic resin film-shaped foam expands, the expansion section escapes to a space from which the core material is removed, thus resulting in no inhibition of the effect of re- expansion, then obtaining the high effect of re-expansion.

Title: Production of galvanized steel sheet
Inventor: SUGIYAMA SEIJI
IPC: C23C2/02
Filed: 1993-05-26
Abstract: PURPOSE:To enable galvanizing which can be maintained with a high degree of adhesion onto a steel strip to be galvanized and does not generate surface flaws. CONSTITUTION:The gaseous atmosphere in a snout 3 is formed as a nonoxidative atmosphere for the steel strip and as an oxidative atmosphere for the bath surface of molten zinc at the time of letting off the heat treated steel strip 1 out of the snout 3 immersed at the bottom end into the molten zinc 5 and subjecting the steel strip to galvanizing. Since the atmosphere is set under the conditions under which the steel strip 1 is not oxidized, there is no degradation in the degree of the adhesion of galvanizing after passage through the plating bath. Since the bath surface of the molten zinc 5 in the snout 3 is set under the conditions to oxidize the bath surface, ZnO is created on the bath surface and acts as a barrier to prevent the generation of the fumes of the molten zinc 5, thereby suppressing the adhesion on the fumes on the steel strip 1 surfaces and the generation of flaws in appearance.
