    摘要： The casting ejector includes a forcibly cooled ejector plate and a plurality of depending, solid ejector pins of high thermal conductivity cooperate with a casting mold to increase the strength of specifying portions of the casting. Copper, nickel, and alloys of each having a thermal conductivity of 40 W/mK or more are used, and the pins are disposed to contact high-stress locations of the casting.

    摘要： There is provided an improvement on a solid-state type color image sensor having a color filter arrangement matching the line sequential color difference signal method. A color filter selected from magenta, yellow and cyan for covering the entire area of each picture cell and a color filter of a different color are superposed one upon the other. The color filters covering predetermined ratios of the areas of associated picture cells are preferably formed collectively in a stripe shape.

    摘要： A split mold is closed to define a cavity. The mold has in its lower portion a gate communication with the cavity. A stoke is connected at its upper end to the gate, while its lower end is immersed in a bath of molten metal in a holding furnace. The pressure of the bath is increased, or the pressure of the cavity decreased, whereby the molten metal is introduced into the cavity. The molten metal in the cavity is allowed to solidify to yield a cast product. The product is cooled and removed from the mold. The stoke and the cavity are filled with an inert gas before the molten metal is introduced into the cavity. In order to introduce the molten metal into the cavity, a pressure difference is created between the bath and the cavity at a rate of 0.001 to 0.006 kgf/cm.sup.2 /s. The molten metal is kept at a temperature which is higher than its melting point by 50.degree. to 80.degree. C., or the mold is kept at a temperature of 350.degree. to 430.degree. C. The inert gas is also supplied into the stoke to separate molten metal therein from the solidified product. The surface of the separated molten metal in the stoke is kept above that of the molten metal in the holding furnace when the product is cooled and removed from the mold.
