Inventor: MORIYA NORIO
IPC: B09B3/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To modify a soil generated by construction into the soil having a strength capable of enabling backfilling by adding small amount of natural polymer-based solidifying agent to the weak soil generated by construction, and having high viscosity to dissolve the solidifying agent in free water, stirring the soil with the solidifying agent to form aggregate, and further adding a stabilizer thereto. SOLUTION: A natural polymer-based solidifying agent (e.g. a copolymer of an acrylamide and sodium acrylate) is added to soil particles 1 floating in free water 2, comprising a clayey generated soil having high water content and organic concentration, and sludge to allow the free water 2 to be absorbed, and the added product is stirred to allow the surfaces of the soil particles to be coated with pseudo fixed water 3. Because the copolymer has coagulating activities, the granulation of the soil particles 1 proceeds by the stirring to form dumpling-like lumps 4. When lime is added thereto as a stabilizer, coating membranes 5 are formed on the surfaces of the dumpling-like lumps 4, and the coating membranes 5 react with water to provide hydrated lime.  As the result, a pozzolan reaction proceeds, the strength of the dumpling-like lump 4 is increased, and the soil becomes the improved soil by further stirring.

Abstract: PROBLEM TO BE SOLVED: To facilitate returning to a yarn winding mode after power failure by providing a main control device common to winding control device corresponding to single spindle driven type multi-bobbin units respective and current supply system power sources at their respective multi-bobbin units and transmitting a power failure detection signal to each winding control device all at once. SOLUTION: When each winding control device 8 receives the power failure detection signal from a power failure detector 26, each winding control device 8 retreat processes the fixed length counter value so that fixed length is stored in a place where even if the multi-bobbin units stop due to power failure, fixed length is not deleted. When a yarn cutting command signal 11 is transmitted to each yarn cuuter from each winding control device 8, and a free running stopping signal is also transmitted to each inverter 18. Then, the yarn cutter cut off yarn, and each inverter 18 stops the free running of a drive motor 12. When the voltage of system current 25 is further decreased, control devices for the inverter 18, etc., and all multi-bobbin units U stop all together.  Therefore, since rewinding from a yarn supply bobbin to a winding package is suspended, recognition of power failure by each unit is consistent with each other.
