摘要： A sample is taken out of a molten magnesium alloy, the cooling curve of the sample during solidification is measured, the content of the aluminum component in the sample is determined by the use of the crystallization temperature of a phase appearing in the cooling curve, together with cooling curves, and if the results of bath analysis show the components to deviate from the standard values and target values, an aluminum-manganese master alloy, aluminum or magnesium is added to the molten magnesium alloy to adjust the components to an appropriate amount of aluminum or an appropriate iron/manganese ratio, whereby a magnesium alloy is produced.

摘要： A method for die-casting a magnesium alloy comprises the step of casting a die cast product free of any hot tearing, shrinkage tearing and shrinkage cavity starting from a magnesium alloy comprising i) 1 to 10% by weight of aluminum; ii) at least one member selected from the group consisting of 0.2 to 5% by weight of a rare earth metal, 0.02 to 5% by weight of calcium and 0.2 to 10% by weight of silicon; and iii) not more than 1.5% by weight of manganese, and the balance of magnesium and inevitable impurities, using a cold chamber type die-casting machine, wherein a) the temperature of the molten magnesium alloy is maintained at 650 to 750°C.; b) the charging velocity of the molten metal is set at {fraction (1/100)} to {fraction (10/100)} second; and c) the intensified pressure after the charging is set at a level of not less than 200 kgf/cm2. Thus, a die cast product free of any hot tearing, shrinkage tearing and shrinkage cavity can be produced by appropriately specifying injection conditions, mold conditions, conditions for melting a magnesium alloy and mold plan in the cold chamber type die-casting machine, or by appropriately controlling the temperature of the molten metal from the molten metal-accommodating pot to the gate portion of the machine.

摘要： A method for the preparation of a hydrocarbon conversion catalyst comprising a composite of a refractory support, or carrier, a Group VIII noble metal component, particularly platinum, a tin component, and a halogen component. Suitably, the catalyst composite can also contain a third metal component, or yet additional components. In the preparation of such catalyst, the tin is added from a solution of a soluble compound of tin comprised of an organo thionyl compound, or organic compound containing a thionyl group, whereby the tin component is uniformly dispersed from the surface into the inner part of a catalyst. Such catalyst is found useful in hydrocarbon conversion reactions, particularly reforming (hydroforming). A naphtha or straight run gasoline can be contacted with such catalyst at reforming conditions in the presence of hydrogen to improve the octane quality of a naphtha or gasoline.

摘要： The present invention has an object of providing a drug carrier capable of controlling in vivo pharmacokinetics. The present invention is directed to a drug carrier comprising a molecular assembly having a drug incorporated therein, and the above object can be achieved by a part of the amphiphilic molecules included in the molecular assembly being released from the molecular assembly by an external environmental change. The present invention utilizes a phenomenon that the hydrophilic-hydrophobic balance of the amphiphilic molecules is shifted toward hydrophilicity by an external environmental change and thus the amphiphilic molecules are freed from the molecular assembly.
