摘要： A method for predicting and preventing occurrence of shrinkage cavity in an iron casting of any of various shapes or in each part of an iron casting precisely prior to casting. The shape of an iron casting is approximated entirely or partially to a rectangular parallelepiped or a cube, to the sum of the two long sides is divided by the short side to determine a shape coefficient, and occurrence of shrinkage cavity is predicted by determining whether the value exceeds a predetermined value (determination coefficient) or not.

摘要： An apparatus and method for casting metal in an evacuated mold cavity. The apparatus has a preferential suction zone through which a mold can be preferentially and effectively evacuated and a suction head sealingly fitting the upper surface of the mold. To the apparatus, is further provided a pressing means for pressing, in cooperation with the suction head, the mold against the inner bottom surface of a mold support chamber. By evacuating the mold through the preferential suction zone while pressing the mold to the bottom of the mold support chamber, a mold cavity is easily filled with a molten metal in such a manner to avoid casting defects such as insufficient filling, blow hole, surface fold, under fill, etc.

摘要： The occurrence of porosity defects in solidifying metal can be predicted by a computer simulation numerically analyzing the solidification process of molten metal comprising (1) dividing a mold and a mold cavity into a plurality of elements; (2) providing each of the elements with material properties of casting metal and mold, and process variables as initial data; (3) calculating a liquid fraction of each of the elements in successive predetermined time increments to examine whether nor not each of the elements is in solid-liquid coexisting zone; (4) calculating pressure gradients between each of elements in the solid-liquid coexisting zone and neighboring elements thereof by numerically analyzing an interdendritic flow of the molten metal; (5) calculating gas pressure in the molten metal in each of elements in the solid-liquid coexisting zone; (6) comparing the gas pressure with an equilibrium pressure, and calculating a porosity amount for each of elements where the gas pressure is higher than the equilibrium pressure; and (7) repeating the calculations of the steps (3) to (6) until the solidification of the molten metal is completed. Since the above method takes the effects of interdendritic flow of molten metal into consideration, the occurrence of porosity defects can be predicted accurately and directly.

摘要： A blood pressure measurement system comprises a determination means for determining whether a cuff pressure is increasing for preparation purposes or decreasing for measurement purposes. The determination means includes a comparator for comparing the current cuff pressure with the last cuff pressure, and detection means for detecting whether a difference between the current cuff pressure and the last cuff pressure is smaller than a predetermined value. Another determination means is provided for detecting whether the cuff pressure is first increased to a desired level higher than systolic pressure of a person to be measured. A reset means is provided for automatically resetting the system when the cuff pressure is decreased to a predetermined level after completion of measurement.
