Title: Beam spot correcting device for cathode-ray tube
Inventor: UBA TOMOHISA
IPC: H01J29/76
Filed: 1985-07-23
Abstract: PURPOSE:To correct distortion of beam spot over the entire area of screen by feeding parabolic current of horizontal scanning period to one yoke of tetra- pole structure while feeding saw-tooth current of horizontal period to the other yoke. CONSTITUTION:Parabolic current IPA and saw-tooth current ISA are fed respectively to the yokes 10, 20 to produce magnetic field. Consequently, respective electron beam BR, BG, BB is subjected to force. In the yoke 10, horizontal and vertical forces will function onto the electron beams BR, BG, BB while in yoke 20, force in the direction of 45 deg. will function onto the yoke 20. Consequently, distortion of beam spot can be corrected over the entire area on the screen.

Title: Method and apparatus for pretreatment of molten iron
Inventor: TANAKA TSUTOMU
IPC: C21C1/00
Filed: 1986-07-10
Abstract: PURPOSE:To execute effective prerefining of a molten iron by giving a fall between a tapping spout and receiving runner of a blast furnace, dropping the molten iron from the tapping spout and adding a pretreating agent to the molten iron during the course of the tapping. CONSTITUTION:The molten iron 14 flowing out of the tap hole 2 of the blast furnace 1 is once received in the tapping spout 3, and molten slag 15 existing in the upper part of the molten iron is removed and separated from a slag discharge port 11 by a skimmer. The molten iron having no molten slag 15 is dropped into the lower receiving runner 5 having the substantial fall. The prerefining agent such as desiliconizing agent and dephosphorizing agent in a hopper is blown to the falling molten iron flow 16 falling from a lance 8 during the course thereof and is thoroughly mixed with the molten iron, by which the Si in the molten iron is converted to SiO2 and the P to P2O5. The stable molten slag 17 is formed by CaO and is discharged from the slag discharge port 12. The molten iron subjected to the prerefining is transferred from an outflow port 6 of the receiving runner 15 into a torpedo car 13. Since the runner 5 is cooled by a cooler 10 using gas such as gaseous N2 or liquid such as water as a heat medium, the damage of the refining refractories thereof is decreased.

Recesses and protrusions 14 formed into an inwardly almost parallel wave- like recess and protrusion shape i.e., a shape of the teeth of a comb are projected between the flat face 13 and the net type recess and protrusion portion 12. When heat sealing is performed by using the upper and the lower heating platens 10, 11, the recesses and protrusions 12 by embossing can be formed at the inner edge portion of a sealing part 31 of a sealed container and, if a distance between the upper and the lower heating platens 15 made shorter on the inner edge side, the depth of sealing becomes gradually deeper toward the inner edge portion. Accordingly, seal strength becomes stronger toward the inner edge portion of the flange.
