Title: Preventing method of molten steel pouring nozzle clogging
Inventor: FUKUMOTO KENZOU
IPC: B22D11/10
Filed: 1979-03-31
Abstract: PURPOSE:To prevent the nozzle from being clogged by the deposition of the impurities in molten steel or the molten steel itself by heating the molten metal near the nozzle inside surface by the skin effect of high-frequency current at the time of pouring the molten steel into the continuous casting mold with the immersion nozzle of the tundish. CONSTITUTION:At the time of pouring molten steel 5 into a continuous casting mold 4 by an immersion nozzle 3 from a tundish 1, the high-frequency voltage of 10000Hz is applied from a high-frequency generator 8 to the electrodes 6 in the tundish 1 and mold 4, by way of an output transformer. The high-frequency current A flowing between the both electrodes 6, 6 passes through the inside of the molten metal near the surface of the immersion nozzle 3 owing to the skin effect of the high- frequency current and heats this portion by Joule heat. The nozzle 3 may be prevented from being clogged by the deposition of the non-metallic inclusions, such as Al2O3, in the molten metal or the molten metal itself on the nozzle inside surface. There is no interruption of the casting owing to the nozzle clogging and productivity improves.

IPC: H01L51/40
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a Y-type cumulative film having a uniform cumulative structure and contg. scarce defects by utilizing a phenomenon positively wherein a meniscus moves spontaneously toward a center of a substrate under conditions satisfying almost thermodynamical equilibrium conditions. CONSTITUTION:A monomolecular film 1 having a surface pressure set at a predetermined pressure is formed by developing org. molecules on a surface of water and compressing the molecules, and the monomolecular film 1 is adhered to a substrate 2 held horizontally. Then, the substrate 2 is lifted to a predetermined height with an extremely slow speed so as to maintain the surface pressure of the monomolecular film at above a fixed value. A force for maintaining a meniscus formed in the periphery of the substrate 2 is exerted on the meniscus by this lifting, causing the meniscus to move automatically toward a center of the substrate 2. The substrate 2 is allowed to stand still at this height position. Thus, a monomolecular film 1 is formed as a Y-type cumulative film on the whole surface of the substrate 2 in accompany with the movement of the meniscus, under a condition where each hydrophilic group of the monomolecular film 1 is bonded to each other.

Title: Thermosetting reinforced fiber prepreg sheet
Inventor: NAKAHARA SADAHITO
IPC: B29K101/10
Filed: 1994-03-10
Abstract: PURPOSE:To contrive to reduce production cost by a method wherein thermosetting reinforced fiber prepreg sheet is produced by employing resin film made of biaxially oriented polypropylene film as releasing base material. CONSTITUTION:Reinforced fiber prepreg sheet consists of reinforced fiber sheet 1 made of continuous fiber impregnated with thermosetting resin and resin film 2 as releasing base material. Since the peeling properties of the resin film 2 to the surface contacting with the reinforced film sheet 1 due to the peeling properties between the resin film 2 and the thermosetting resin is different from the peeling properties of the resin film 2 to the rear surface not contacting with the reinforced fiber sheet 1, no separation from the surface develops at the winding up in roll or re-unwinding from roll. Further, stretching is prevented from developing, since biaxially oriented polyproplylene is employed as the resin film 2. Furthermore, by employing cheap film 2 as just mentioned above, the reduction of production cost can be contrived. In addition, the resin film 2 produces a few industrial waste from disposal incineration.
