Abstract: PURPOSE: To effectively perform the complete fermentation treatment of sludge by dividing and arbitrarily combining storage tank, fermentation tank, lower fermentation tank, and carry-out fermenting treatment according to the property and maturity of the sludge to be treated.  
     CONSTITUTION: A substance to be treated by fermentation, e.g., sludge, is put in a raw storage tank A, where it is stirred by rotation of a stirring blade 2 and flowed from the cutback floor 3 at the bottom into a fermentation tank B or directly a hopperlike lower fermentation tank C for fermentation treatment. In this case, these tanks A, B, and C are combined in the manner of A-B-C-D, A-A-C-D, A-A-B-C-D, etc., according to the property and muturity of sludge to be treated. The substance treated by fermentation is carried out by a carry-out means 7, e.g., screw conveyer, etc., jointed to the lower part of the lower fermentation tank 7. By this method, a continuous fermentating treatment can be performed without the needs for such pretreatments as mixing, granulation, storage, etc.

Abstract: PURPOSE:To obtain a rope for pulling an electric wire, improved in waterproofness and excellent in high strength properties by coating a rope unit with a synthetic resin layer formed on the outer periphery of the rope composed of ultrahigh-strength fiber and further carrying out resin finish there on. CONSTITUTION:A rope body 1 composed of ultrahigh-strength and low-elongation type synthetic fiber, e.g. aramid fiber or wholly aromatic polyester fiber is impregnated with a synthetic resin having a relatively low viscosity (e.g. polyurethane resin) to form a synthetic resin layer 2 on the outer periphery of the rope body. The outer periphery thereof is then covered with a cylindrical rope unit 3 composed of, e.g. polyester fiber. A synthetic resin having a relatively high viscosity (e.g. the polyurethane resin) is further impregnated from the outer periphery of the rope unit to the internal direction to form a synthetic resin layer 4 to be integral with the synthetic resin impregnated into the outer periphery. Thereby, the objective rope for pulling electric wires having high strength properties and excellent waterproofness is obtained.

Abstract: PURPOSE: To make etching mith ion beam possible by generating plasma with electric discharging of microwaves to form ions and combining a microwave reflecting plate and a floating electrode plate, to form ion shower.  
     CONSTITUTION: The microwaves introduced through a waveguide 5 and an introduction window 4 into a plasma generating chamber 1 cause resonant electric discharging by the magnetic fields generated by a magnetic coil 6, and generate plasma which forms the ions of the gas supplied from the 1st gas introduction system 16.
