Title: Blowing out method for blast furnace
Inventor: YOSHIMURA KENZOU
IPC: C21B5/00
Filed: 1978-12-25
Abstract: PURPOSE:To save labors and to reduce time required to blow out a blast furnace remarkably, by using coke of small lumps, and by raking out the hot substance in the furnace while operating with a lowered stock line. CONSTITUTION:A blast furnace is blown out with a lowered stock line. During the blowing out operation, coke of small lump about 10-30mmphi in diameter is used. The stock line is lowered according to the charging rate of raw materials determined on the basis of a stock-line-lowering plan. When the stock line is lowered finally near the belly, the blast is stopped, then the substance in the furnace is raked out while hot from the tuyere 2 through a shoot 4 into a cinder ladle 3. The shoot 4 is provided with a cooling box 9 and a spray means 5 so as to cool the material which is raked out. This process permit to decrease the substance which remians in the furnace after completion of blowing out, and makes the raking out easy, so that the blowing out is conducted by less number of labors in a short time.

IPC: H03H9/36
Filed: 1979-12-14
Abstract: PURPOSE:To insulate a high molecular piezoelectric film from external acoustic sound and light rays by setting the main direction of propagating vibration wave produced at an input electrode perpendicularly to an electrode confronting direction and reducing the reflecting noise applied to an output electrode. CONSTITUTION:Since the elongating and contracting motion of a film due to reverse piezoelectricity produced at input side electrodes 1, 1' occur in the main orientation axial direction (an MD direction of arrow) of the film when electrode pairs 1, 1' and 2, 2' are confronted in the vicinity at an equal interval, the vibration wave is propagated in the MD direction, and is reflected at both ends of the film in the MD direction. If the MD direction of the film is a direction perpendicular to the electrode confronting direction as designated by an arrow (b), the main direction of the vibration wave propagating from the electrodes 1, 1' is a direction as designated by (b), and almost no reflecting wave noise is applied to the electrodes 2, 2'. Thus, the film can be insulated from external acoustic sound and light rays.
