Title: In-bath impurity removing device in zinc pot
Inventor: KAWAGUCHI KATSUNORI
IPC: C23C2/00
Filed: 1989-12-11
Abstract: PURPOSE:To easily remove the in-bath impurities in a zinc pot of a plating line by rotating a gas-blowing lance having vanes in the zinc pot. CONSTITUTION:The gas-blowing lance 1 with vanes is rotatably mounted in the zinc pot 4 of the galvanizing line. Bubbles 7 generated by the rotation of the revolving lance 1 with the vanes capture the in-bath impurities 6 and float on the bath surface. The bubbles 7 displace a top dross film 2 and tend to spread the top dross film 2 over the entire area of the bath surface but the top dross film 2 is stopped by a frame 3. The execution of the recover of the top dross at customary frequencies suffices accordingly. The inspection and service of the lance 1 by pulling the lance from the bath together with blowing and lifting the lance 1 by a lifting device 8 are facilitated.

Abstract: PROBLEM TO BE SOLVED: To provide an arbiter provided with ability to update the priority of respective devices so as to improve the efficiency of a system when the plural devices request access to a data bus. SOLUTION: The arbiter 103 connects the plural devices A-D to a bus 101 and the arbiter 103 decides the priority among the devices based on the relative necessity of the devices A-D.
