Title: Reduction of air blowing during reduced scale blowing-down operation of blast furnace
Inventor: HATANO MICHIHARU
IPC: C21B5/00
Filed: 1979-02-19
Abstract: PURPOSE:To stabilize reduced scale operation by preventing the blowing-through by the procedure in which a furnace index of blowing-through is obtained from blast furnace model during reduced scale blowing-down operation, a limited air blowing at which the index does not exceed a fixed value is obtained for each reduced scale process, and then air sending is performed. CONSTITUTION:By using a model to grasp the dynamic behavior of blast furnace during reduced scale operation, the furnace distribution of blowing-through index is obtained from a balance between pressure loss and charging load at each portion of furnace, and then limited air blowing amount at which the blowing-through index does not exceed a fixed value is obtained for each reduced scale process. Then, air blowing is made at less than the limited air blowing amount obtained according to reduced scale operation condition. Thus, smooth reduced scale blowing-down operation can be performed without causing blowing-through of air in the final period of operation.

Filed: 1985-02-05
Abstract: PURPOSE:To improve the magnetic adsorbing force by supporting a movable permanent magnet on a movable body such that the magnetic pole face will face against the magnetic pole member of a face plate while slidably thereby reducing the leakage flux between the movable permanent magnet and the face plate. CONSTITUTION:Under excited state, one magnetic pole face of a movable permanent magnet 20 is contacting directly against the corresponding magnetic pole member 22, thereby the flux from the permanent magnet 20 to the magnetic pole member 22 and from the pole member 22 to the permanent magnet 20 will never pass through a chip in conventional chuck but flow directly. Consequently, the magnetic path is shortened to reduce the leakage flux, thus to function the magnetic force of the movable permanent magnet 20 effectively onto the face plate 14. As a result, the magnetic loss can be reduced when compared with the conventional chuck resulting in improvement of the magnetic adsorbing force of the face plate 14.

Title: Measuring method for fine grain in solvent
Inventor: KOSAKA YASUO
IPC: G01N15/10
Filed: 1988-01-29
Abstract: PURPOSE:To efficiently execute an exact measurement by diluting a solvent by superpure water, converting it to aerosol, measuring the grain diameter and the number of pieces of a solid fine grain by a light-scattering fine grain counter and subtracting the number of pieces of only superpure water from this measured value. CONSTITUTION:A solvent is diluted in a suitable ratio by superpure water, mixed and injected with clean air A which has passed through a filter 2 and becomes aerosol, and a droplet exceeding a prescribed grain diameter is eliminated by a droplet separator 4. A droplet being smaller than said droplet goes into a cavity 6 together with air, and also, water content is eliminated by a heater 7. Subsequently, said aerosol is cooled and dehumidified by a cooler 9 and fed to a light-scattering fine grain counter 10. The counter 10 divides fine grains into each grain diameter and counts the number of pieces. Next, by subtracting the number of pieces of only superpure water from the count number, the number of pieces of solid fine grains of the solvent itself is derived. In such a way, an exact measurement can be executed efficiently.
