摘要： After a cavity 2 of a die-casting mold 1 is evacuated to exclude gases, oxygen gas is blown into the cavity 2 until an internal pressure of the cavity exceeds the atmospheric pressure, and then a molten metal 5 is forcibly injected into the cavity 2. The cavity 2 is evacuated to a degree of vacuum less than 100 millibar through a suction nozzle 11. The oxygen gas is blown through a nozzle 14 into the cavity 2 so as to fill the cavity 2 with the oxygen gas at an internal pressure higher than the atmospheric pressure. When the molten metal 5 is injected into the cavity 2 clarified in this way, inclusion of gases is perfectly prohibited. As a result, obtained die-cast products are free from defects such as blowholes or porosity caused by inclusion of gases and so useful as functional members as well as structural members.

摘要： In the brazing of aluminum a flux composed of a mixture of alkali metal fluoaluminates, with or without admixed AlF.sub.3, is employed. The flux has a composition of AlF.sub.3 about 53-62%, KF about 35-44%, and LiF about 2-7%, in terms of simple compounds. The flux has a liquidus temperature in the range of 490.degree.-560.degree. C. depending on its actual composition. The flux is of particular utility when brazing aluminum containing 0.4-2% magnesium and/or having a low solidus temperature and is preferably employed in an atmosphere of a dry, inert gas.

摘要： An impurity measuring device includes a table (T) on which a sample (S) is to be placed with its fracture surface (h) facing up, an illuminating means (7) for irradiating the fracture surface (h) with light (L) from a plurality of directions, an image sensing means for sensing an image of the fracture surface (h) irradiated with the light (L), continuous tone color image processing means for processing the sensed image into a continuous tone color image, and a binarizing means for binarizing the continuous tone color image through comparison between the result of the continuous tone color image processing and a threshold value. As the fracture surface (h) is irradiated with the light (L) from the plurality of directions, the image obtained by sensing the image of the fracture surface (h) is free from shading or optical irregularities caused by minute irregularities on the fracture surface (h). Therefore, impurities in the sample (S) can be accurately detected from the fracture surface (h) by subjecting the image to the continuous tone color image processing and binarization.
