Title: Method for rolling checkered steel plate
Inventor: IWAMOTO SHIGENOBU
IPC: B21B27/00
Filed: 1990-06-06
Abstract: PURPOSE:To spread water on neither upper surface nor lower surface of a steel plate irrespective of injection of water to both upper and lower surfaces of the steel plate by arranging a pair of a caliber work roll on the lower side and a flat work roll on the upper side at the final stand of a finishing mill and forming checkered projections on the surface of the lower side of the steel plate. CONSTITUTION:At the final stand of the finishing mill, the steel plate 4 is rolled down by a pair of an upper flat work roll 1 and a lower caliber work roll 2 to form reticulate projections on the lower surface. Then, on the outlet side of the finishing mill 6, water is injected by runout sprays 5 on both upper and lower surfaces of the moving steel plate 4. After finish rolling is completed, water droplets hardly remain on the surface of the flat upper side of the steel plate 4 and water hardly spreads. Further, water droplets hardly remain even on the surface of the lower side of the steel plate where projections are formed and water hardly spreads.

Title: Chemical pyrolysis process of halogenated hydrocarbon under air isolation
Inventor: HANSU FUSHIYUKA
IPC: B09B3/00
Filed: 1990-06-08
Abstract: PURPOSE: To prevent such formations as dioxin and furan, a molten substance or an irreversible film, and generation of secondary wastes to be disposed, by chemically and thermally decomposing halogenated hydrocarbons under air shut off through a reaction using a stoichiometrically excess amount of calcium oxide and/or calcium hydroxide at a specified temperature in a reactor. CONSTITUTION: Along with calcium oxide and/or calcium hydroxide, 1-10 pts.wt. of sand to 1 pt.wt. of calcium oxide are located in a reactor. The reaction product composed mainly of a calcium halide and sand is de-halogenated by steam at 150-800 deg.C in another reactor. By putting a mixture of calcium oxide and sand thus obtained back into the first reactor, production of a secondary waste is prevented from forming in a remarkably large quantity comparing to the flow rate of halogenated hydrocarbon.

Abstract: PURPOSE:To prevent a sliding portion from being damaged by a foreign matter, by providing a ceramic plate formed on its both surfaces with spiral grooves having counter directions and a ceramic plate formed on its one surface with a spiral groove. CONSTITUTION:A ceramic plate 6 is formed on its both surfaces 6a and 6b with spiral grooves having counter directions A ceramic plate 7 has a flat upper surface 7a and a lower surface 7b formed with a spiral groove. When a rotary shaft 1 is rotated in a direction of an arrow 12, a fluid existing between the surface 6a and an end surface 4 flows toward the outer circumference along the spiral groove. As a result, a land of the upper surface 6a is attracted to contact the end surface 4, and the ceramic plate 6 is rotated integrally with an end surface member 2. As a result, there is generated a force for making the fluid flow from the outer circumference toward the inner circumference along the spiral groove on the lower surface 6b. This force serves as a dynamic pressure to form a fluid film at a sliding portion between both the ceramic plates 6 and 7. Accordingly, even when a foreign matter enters the sliding portion, the latter is not damaged.
