    摘要: A continuous casting method includes the steps of continuously supplying molten metal into a mold through at least one feed nozzle connected to the mold through a break ring, with the feed nozzle, the mold and the break ring forming at least a portion of a continuous casting apparatus, and intermittently withdrawing a cast piece formed from the molten metal in the mold thereby creating pressure in a space formed at a connecting point between the break ring, the mold and the cast piece as a result of the withdrawal from the mold. A shield means is placed to seal-off space between the at least one feed nozzle, and the mold to prevent entry of gas into the continuous casting apparatus and the pressure is reduced in the sealed-off space to thereby eliminate a pressure differential between the pressure in the sealed-off space and the pressure created in the space formed at the connecting point between the break ring, the mold and the cast piece during the intermittent withdrawal from the mold.

    摘要: A panel shutter device constructed in such a way that in the process of continuously moving each panel by a lifting shift along guides rails and a lateral shift along a housing rail, a guide rotary member engages or disengages a guide shaft projecting from the side of the panel opposite the driven side. At the time of descending of the shutter curtain, in order to prevent finger pinching as each panel is placed on the succeeding panels sequentially, each panel can be lifted or descended without causing a gap between panels of the shutter curtain by providing the support member suspended by a pivotable connecting chain.

    摘要: A GaAs epitaxial layer is formed on a semi-insulative GaAs substrate by use of a crystal growth technique which allows control on the order of atomic layer level. A metal film is formed on the GaAs epitaxial layer by use of the same crystal growth technique. Ions are implanted in source and drain high-concentration layer-forming regions, through the metal film, and are activated.
