IPC: B63B35/00
Filed: 1980-02-25
Abstract: PURPOSE: To prevent water pollution during dredging operation by providing a cover of an unbrella-shape near the front end of a pressure water injecting pipe and a muddy water suction pipe and providing a muddy water storage on the bottom of a dredger.  
     CONSTITUTION: A cover 10 of a unbrella-shape is attached to the front end part of a pressure water injecting pipe 4 and a muddy water suction pipe 5 each provided for a dredger and an expandable muddy water storage bag made of a flexible material is provided on the bottom of the dredger. When the rocks and mud of the water bottom are loosened by the action of the pressure water injecting pipe 4 and the water became muddy, the muddy water is prevented from dispersing by the cover 10. The muddy water sucked in together with the rocks and mud by the suction pipe 5 and separated from the rocks and mud is contained in the storage bag and recirculated as the pressure water for dredging so that the water will not be polluted.

Title: Out-of-furnace detitanating method of molten iron
Inventor: TAKAHASHI YOSHIO
IPC: C21C1/04
Filed: 1979-03-01
Abstract: PURPOSE: To remove and reduce the Ti in casting iron in preference to other component elements by adding slag-forming agent more than once and N compound more than twice or continuously to molten iron and capturing Ti nitrides formed as slag.  
     CONSTITUTION: A slag forming agent (e.g. limestone, Na 2 CO 3 ) is added more than once and N compound (e.g., CaCN 2 , Si 3 N 4 ) not less than twice or continuously to molten iron (particularly casting iron Class 3). Thence, the TiN formed is mechanically captured as slag and is floated on th molten iron surface and is thereby separated. According to this method, the iron making raw materials such as iron ore which have been infeasible to be compounded or whose compounding amount has been limited owing to high Ti contents may be used or increased ore amount. Further, iron kinds have hitherto been properly blown while attention is being given to the Si and Ti amounts in the pig iron, but according to this method, the charged Ti amount will not rate-determine the action in the blast furnace operation, thus the blast furnace operation stabilizes.

Filed: 1988-02-05
Abstract: PURPOSE:To simply execute a stable and highly accurate fine processing operation without damaging a substratum of an object to be etched by a method wherein an upper-layer part is etched so as to contain the vertical side and the protruding bottom and, after that, a photoexcited etching operation is executed. CONSTITUTION:When a dry etching operation of an upper-layer part of a layer to be etched is executed by incidence of a charged particle, the side where a substrate is not arranged is grounded and the etching operation is executed down to a desired depth under conditions o//f a low pressure and large high-frequency electric power in such a way that the bottom of a groove formed between masks 33 has a protruding shape 34, and, after that, a photoexcited etching operation is executed. Accordingly, when the protruding shape is processed by a reactive ion etching operation, it is possible to avoid that an etched shape after the photo-etching operation trails a skirt; it is not required to add a deposition gas during the photo-etching. By this setup, it is possible to avoid a drop in the efficiency due to an unstable deposition of a side-wall protective film, to avoid a complex operation to introduce a gas and to avoid the labor for removal of the side-wall protective film; performance and efficiency are enhanced.
