Title: Path selection system for switch network and switching element
Inventor: INOUE HIROSHI
IPC: H04L12/28
Filed: 1988-04-12
Abstract: PURPOSE:To prevent a data subjected to correct routing from being caused in an erroneous routing by a data stepping out of the substantial routing by providing a flag bit in the header of a data and setting a flag displaying a win/defeat in the contention at collision. CONSTITUTION:A flag bit is provided in the header of a data, and when no defeat display is given in the flag bit of the data in the collision of plural data, the data of an input line with higher priority is sent to an output line designated by a routing tag and the data of an input line with lower priority is outputted to the remaining output line while displaying defeat. If defeat is displayed only to one data, the data without defeat display is outputted to an output line designed by a routing tag regardless of the priority of the input line and the data with defeat display is outputted to the remaining output line. Thus, the disturbance of the routing of the data subjected to correct routing is prevented by a data stepped out of the substantial routing.

Title: Electromagnetic stirrer in mold
Inventor: KADOI JIYUN
IPC: B22D11/10
Filed: 1984-05-04
Abstract: PURPOSE:To prevent the thermal stress cracking of a billet and intrusion of powder therein while maintaining a substantially high speed of a molten metal by placing an electromagnetic coil which acts a moving magnetic field to the molten metal in a mold for continuous casting so as to face the mold and inclining the coil relative with the center line of the mold. CONSTITUTION:The moving magnetic field type electromagnetic coil 1 is disposed to face the mold 2 and is inclined by an angle theta of inclination relative with the center line of the mold 2. The molten metal 6 poured from a tundish 3 via an immersion nozzle 5 into the mold 2 is fluidized by the coil 1. Rotating flow is generated in the molten metal by reversing the moving direction of the magnetic field of the coil 1 facing the mold. Thrust acts on the molten metal 6 in the mold 1 on the side in proximity to the coil 1 and the flow direction changes in the corner part. Meniscus 4 builds-up in the corner part and the flow is consequently disturbed, but if the above-described angle theta of inclination is provided, the collision of the molten metal 6 perpendicularly against the mold wall is averted. The build-up of the meniscus 4 is thus prevented and the purpose is achieved.
