Title: Method for operating blast furnace
Inventor: SHIMOMURA AKIO
IPC: C21B5/00
Filed: 1989-07-20
Abstract: PURPOSE:To suppress the solution loss of charged coke and to allow the use of low quality coke by blowing pulverized coal contg. a high-volatile component together with a blast furnace gas from the shaft part of a blast furnace into the blast furnace. CONSTITUTION:The pulverized coal contg. the high-volatile component is blown together with the blast furnace gas into the furnace from plural blowing lances 1 provided in the shaft part 4 in the upper part of a fusion zone 2 of the blast furnace in the method for operating the blast furnace by charging coke from the furnace top into the furnace. This pulverized coal easily induces a solution loss reaction. The solution loss in the shaft part of the coke charged into the furnace from the furnace top is suppressed in this way. The cost of a molten iron is, therefore, reduced by charging and using a large amt. of low-grade coke without degrading the furnace conditions.

Title: Discharge tube
Inventor: SHIMOJO TOKUHIDE
IPC: H01J61/067
Filed: 1992-06-24
Abstract: PURPOSE:To increase discharge current and attain a longer life even in the case of high luminance emission by forming a second electrode from a metal having a low sputtering yield by cation, and providing a metal film having high secondary electron emitting property on the inner surface of the electrode. CONSTITUTION:A second electrode 42A is formed of a composite structure consisting of a cylindrical electrode 42A1 formed of a metal having a low sputtering yield by cation, for example, Al, and a metal film having high secondary electron emitting property formed on its inner surface, for example, an Ag-Cs metal film 42A2. On the outer circumferential part of a cylindrical first electrode 41, the electrode 42A is caulked and fixed to its root part, enclosing the electrode 41, and arranged in a determined position concentrical to an inner lead 3. Thus, the secondary electron current from the inner surface film 42A2 can be utilized as discharge current even in the case of the cylindrical electrode 42A1 never reaching the temperature causing thermion emission because of its less rise of electrode temperature, a high current can be carried without increasing the load of the electrode 41. Thus, a high luminance and a long life can be attained.

IPC: G03G15/08
Filed: 1985-08-27
Abstract: PURPOSE:To facilitate adjusting operation and to qualify density control by forming a reference image for toner supply control in either of reversal or normal development modes. CONSTITUTION:The surface potential of a photosensitive drum 1 is made negative by an electrostatic charger 2 in both reversal developing operation and normal developing operation. Therefore, the negative potential of the drum 1 is erased by the exposure of a light emitting element in either case when a reference image formation area passes through an eraser 8. Then, a formed reference latent image is developed on a reversal basis by a developing device 4 wherein a negative bias is applied to the developing sleeve 42 to obtain the reference image. The reflection density of this image is detected by a light emitting element 9a and a photodetecting element 9b and compared with a reference value to supply toner. This operation is not always in the reversal development mode and may be in the normal development mode. consequently, the equipment adjustment is facilitated and the density control is qualified.
