Title: Magnesia-carbon unburned refractory brick and molten steel vacuum degassing treatment equipment lined with the same
Inventor: GOTO KIYOSHI
IPC: C21C7/00
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To improve wear resistance of magnesia-carbon unburned refractory brick without adversely affecting corrosion resistance and spalling resistance of the brick. SOLUTION: This refractory brick has a blending composition that comprises a refractory aggregate composition containing 1-12 wt.% of thin expanded graphite having a <=12 μm thickness, 0.5-10 wt.% of silicon carbide having particle size passing through the 150 mesh Tyler standard sieve and the remainder of a material consisting essentially of magnesia on the basis of 100 wt.% of the refractory aggregate composition, and also a metal powder and a binder, both of which are added to the refractory aggregate composition. In the refractory brick, since oxidation of silicon carbide is inhibited from being caused by the presence of expanded graphite and also, magnesia-carbon reaction is inhibited from being caused by the presence of silicon carbide, wear resistance can be improved without increasing the graphite content of the brick.  As a result, corrosion resistance, spalling resistance and wear resistance of the brick can concurrently be secured.

Title: Wave receiver for propulsion
Inventor: MORI KENICHI
IPC: B63B1/32
Filed: 1993-04-15
Abstract: PURPOSE:To improve the propulsion efficiency by providing a wave receiver for propulsion on an appropriate position of the front part of the outside plating of the bow part of a hull. CONSTITUTION:Wave making resistance at advancing navigation of a ship is largely related to the bow construction of the ship and the shape and speed of the hull.

By providing a wave receiver 1 for propulsion on an appropriate position of the front part of the shell plating of the bow part of the hull, the receives the wave made by the ship, the hull largely receives force in the bow direction by the impulsive force of wave made by the ship. Hereby, speed of the ship is increased, loss energy is converted to a part of the propulsive force, and hence the propulsion efficiency is improved.
