Title: Rolling mill
Inventor: MIKAMI MASAO
IPC: B21B13/14
Filed: 1992-02-24
Abstract: PURPOSE:To precisely control the dispersion of thickness of a plate material by offsetting upper and lower rolls to a rolling line in the direction of a rolling line in a structure wherein upper and lower work rolls are crossed and providing a horizontal bending device in work rolls on one hand. CONSTITUTION:When a cross angle between an upper pair roll composed of an upper work roll 1 and an upper backup roll 3 and a lower pair roll composed of a lower roll 2 and a lower backup roll 4 is adjusted, the profile control of a secondary curve can be carried out extensively to a plate material 5.

Title: Production of stainless steel sheet
Inventor: HAGIWARA TOSHIYA
IPC: C23G3/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the development of flaw and roughening on the surface of a finish product, in a producing method of a stainless steel sheet. SOLUTION: An annealing after cold-rolling is executed in the atmosphere containing the air of less quantity than the necessary min. quantity to the complete combustion of the combustion gas, and after removing scale produced in this annealing, a finish coldrolling is executed. In the case of executing the annealing under condition of less air quantity mixed in the combustion gas than the theoretical air quantity, oxidized scale having a spinel type crystal structure such as FeCr2 O4 or Fe3 O4 , is easily developed. Since the oxidized scale having the spinel type crystal structure is formed as thick-state, at the time of removing the scale, the scale, the flaw generated at the time of hot- rolling and coldrolling, is easily removed. The surface after removing the scale, is roughened, but the surface is recovered by executing the finishrolling, thereafter.

IPC: G02B6/10
Filed: 1985-04-08
Abstract: PURPOSE:To obtain a plastic optical fiber having superior resistance to heat and repeated bending, improved shock resistance, lateral pressure characteristics and a small optical transmission loss by specifying the constituent materials of a fiber. CONSTITUTION:The plastic optical fiber is composed of a core material layer made of polycarbonate, a sheath material layer made of a polymer having repeating units represented by the formula and a protective layer as the essential structural units. The melt flow rate [MFR]1 of the polycarbonate for the core material layer and the melt flow rate [MFR]2 of the polymer for the sheath material layer measured at 230 deg.C test temp. under 5kg test load take values satisfying relations 3g/10min<=[MFR]1<=30g/10min and [MFR]1<=[MFR]2<=40g/10 min. The protective layer is made of an org. polymer having <=5,000kg/cm<2> bending elasticity. In case of [MFR]2<[MFR]1, the polymer in a nozzle is liable to form a turbulent flow, and the optical transmission loss is increased owing to the uneven interface between the core and sheath. In case of [MFR]2>40g/10min, unevenness in the coating of the sheath is increased.

Title: Prevention of adhesion of slag to metal mixing truck
Inventor: TAKASHIMA MASARU
IPC: C21C1/06
Filed: 1979-06-12
Abstract: PURPOSE:To make the discharge of molten pig iron easier by lowering the melting point of slag and at the same time by expanding its volume by a means in which a heat-expansible natural mineral is added to a high-melting high-CaO slag formed when molten pig iron in a metal mixing truck is subjected to a desulfurization treatment with a Ca desulfurizing agent. CONSTITUTION:A Ca desulfurizing agent, e.g., calcium carbide, lime nitrogen, lime, etc., is added to molten pig iron in a mixer for desulfurization. In this case, high-melting slag is formed because of the presence of a great amount of CaO, making the outflow of the high-CaO slag from the mixer difficult and also causing its adhesion and deposition near the pig iron outlet. In order to prevent the trouble, the particles of a heat-expansible natural mineral, e.g., obsidian, perlite, shale, potash-quartz dolerite, etc., are added to the said high-CaO slag, whereby the high- CaO slag becomes a low-melting CaO-SiO2-Al2O3 slag having a high fluidity. Thus, the slag expands, overflows from the molten pig iron outlet of the mixer, and goes out of the mixing truck easily.
