Title: Device for heating molten steel in ladle
Inventor: YOSHIDA MASAHIRO
IPC: C21C7/00
Filed: 1992-01-28
Abstract: PURPOSE:To prevent the remarkable erosion at a slag line in a ladle caused by the slag at the time of heating, in the heating of molten steel in the ladle. CONSTITUTION:A cylindrical protector 18 is arranged around electrodes 6 for heating the molten steel and dipped into the molten steel 8 at this tip part and the slag 10 at the time of heating is held into the protector 18 so that the slag line in the ladle 2 is not directly contact with the slag 10. Since the slag does not come into contact with the slag line in the ladle, the damage of the slag line is prevented and the ladle for exclusively heating the molten steel is dispersed with the countermeasure lining an expensive brick on the slag line.

Title: Developing unit for electrophotographic recording device
Inventor: HISAMA KAZUNAGA
IPC: G03G15/08
Filed: 1994-03-08
Abstract: PURPOSE:To prevent a developer from being fused to an electrifying blade and dispense with troublesome maintenance. CONSTITUTION:The doctor blade 15 of the developing unit 4 generates friction heat when it is brought into slide contact with a toner or a developing roller 12 at the time of development. When the heat quantity generated by this friction is small, most of the friction heat is radiated from the doctor blade 15, and the doctor blade 15 is kept at a low temperature. As the heat quantity generated by the friction is increased, the ratio of the heat quantity conducted to a heat sink 21 is increased. The heat sink 21 has a high heat conductivity and a large surface area, the heat from the doctor blade 15 can be efficiently discharged to the outside, and the temperature rise of the doctor blade 15 due to the friction heat can be suppressed.

Title: Controlling draft rate distribution in sintering machine
Inventor: OTOHATA TETSUYA
IPC: C22B1/20
Filed: 1979-03-28
Abstract: PURPOSE: To enhance the quality of sintered ore such as reduction/powdering ratio without using adjustment of wind box damper by a method wherein fine powder dust is used to cover the surface of filled layer near ore-discharge section in continuous, lower-sucking type sintering machine so that air passing through filled layer is controlled.  
     CONSTITUTION: Powdered dust constant quantity feeder 7 consisting of charge hopper 7 1  and drum feeder 7 2  is installed near ore-outlet 6 of sintering machine so that dust from dust collector is fed on the surface of nearly completely sintered layer on the pallet. By changing the quantity of feed, the amount stacked on the filled layer is controlled and draft distribution in the direction of pallet conveyor 1 movement is controlled. This reduces the rate of air passing through the filled layer at the side of ore-outlet 6 in the sintering machine, so that the lower section of the sintered ore layer is maintained at high temperature. Because, this is rapidly cooled when the ore is discharged, FeO present in the sintered ore is prevented from changing into Fe 2 O 3 . Thus, reduction/powdering ratio is enhanced together with the total quality of sintered ore.
