Title: Continuous casting method of high melting metal
Inventor: WATANABE HIROSHI
IPC: B22D25/02
Filed: 1984-11-06
Abstract: PURPOSE:To prevent troubles such as mold defect and the clogging of a molten metal in a nozzle part by using a casting mold consisting of a material having specific heat conductivity and sliding and moving the top end of a nozzle for casting the molten metal while maintaining the tight contact with the surface part of the casting mold. CONSTITUTION:The casting mold consisting of the material having <=0.1Cal/ cm.sec. deg.C heat conductivity at 800-1,000 deg.C is used. The top end of the nozzle 15 for casting the molten metal is so constituted as to slide by maintaining the tight contact with the surface of the casting mold to suppress the heat dissipation at the top end of the nozzle as far as possible. The molten metal 14 is smoothly cast into casting hole parts 11, 12, 13 of the casting mold when the top end of the nozzle 15 moves to arrive at said hole parts. The continuous casting mold is thus obtd. without providing a valve, plug, etc. to the nozzle part 15 and the troubles such as the clogging of the molten metal and contamination are averted.

Abstract: PURPOSE: To specify whether a data error is caused on a transmission line or on the interface side by converting the back light of the active/stand-by laser diodes through an optical transmission device having a dual transmission system and monitoring the coincidence between respective data. CONSTITUTION: The intra-device signal is turned into a data frame after a frame synchronizing signal FSYNC and an error check signal CRC are produced and added together in an active transmission line interface circuit 1 and an alternative circuit interface circuit 2 via a transmission signal generation circuit 7. Then the transmission signal is converted into an optical signal from an electric signal by an E/O converter 8, and the same transmission signal is sent to both working and alternative optical fiber transmission lines 4 and 5 respectively. Under such conditions, the back light generated in the opposite direction to an LD is received by a photodiode PD. This optical pulse is converted into an electric signal and inputted to a active/alternatvie coincidence monitor circuit 11 for execution of the collation processing.  Thus the occurrence of a transmission data error can be accurately detected.
