摘要： Disclosed is an aluminum-diamond composite having both high thermal conductivity and thermal expansion coefficient close to those of semiconductor elements, which is improved in platability in the surface and surface roughness so that the composite becomes suitable for use as a heat sink of a semiconductor element of the like. Specifically disclosed is a plate-like aluminum-diamond composite containing diamond particles and a metal mainly composed of aluminum. The aluminum-diamond composite is composed of a composite part and surface layers formed on both sides of the composite part, and the surface layers are composed of a material containing a metal mainly composed of aluminum. The diamond particle content is 40-70% by volume of the entire aluminum-diamond composite.

摘要： An apparatus and method for melting and forming metal in a vacuum environment. Metal is formed by melting the metal within a metal-forming apparatus and filling the molten metal into a mold cavity. The metal is melted and formed in a high-level vacuum environment that is created in the apparatus by drawing air from the apparatus in the state in which atmospheric air is prevented from entering the apparatus. It is therefore possible to prevent the properties of the molten metal from changing through contact with the air, thereby forming a high-quality precision metal product.

摘要： A casting apparatus for producing a casting by pouring a metal melt into a gas-permeable casting mold by gravity, comprising: a gas-permeable casting mold comprising a cavity including a sprue composed of a tubular portion and a cup portion having a larger diameter than that of the tubular portion to receive the metal melt, a runner constituting a flow path of the metal melt supplied through the sprue, and a product-forming cavity to be filled with the metal melt sent through the runner; a means for pouring the metal melt into the sprue by gravity; a gas-blowing unit comprising a gas-ejecting member to be connected to the sprue; and a mechanism for moving the gas-ejecting member; the gas-ejecting-member-moving mechanism placing the gas-ejecting member at a position just above the tubular portion and not interfering with gravity pouring of the metal melt, and moving it downward for connection to the tubular portion; the gas-blowing unit having blowing a gas to fill the product-forming cavity with the metal melt. A casting device used to obtain a cast article by gravity casting of molten metal into a porous mold, said casting device having: a porous mold having, as a cavity, at least a sprue part comprising an introduction pipe portion and a sprue cup portion which has a larger diameter than the introduction pipe portion and which receives the molten metal, a runner part forming a flow path for the molten metal supplied from the sprue part, and a product formation part which is filled with molten metal via the runner part; a pouring device capable of gravity-pouring molten metal into the sprue part; a gas-feeding device equipped with a gas discharge part capable of being connected to the sprue part; and a gas discharge part moving device capable of moving the gas discharge part. The gas discharge part moving device lowers the gas discharge part, which had been arranged at a position that is directly above the introduction pipe portion and does not obstruct the gravity-pouring of the molten metal, so as to connect the gas discharge part to the introduction pipe portion. The gas-feeding device feeds a gas so as to fill the product formation part with the molten metal.
