摘要： PROBLEM TO BE SOLVED: To provide a washing device, for which large-scale traffic regulation is made unnecessary and which has excellent washing efficiency and the small discharge of drainage, when a reflecting panel in the tunnel of an expressway or the like is washed. SOLUTION: A slender vessel-shaped hood 10 in which a brush 9 is implanted at a peripheral end is pushed against a reflecting panel 3 on a tunnel interior wall 2 or the like. Nozzles 7 are arrayed in the vertical direction on a manifold 6 in the hood 10, and a high-speed water jet blown out from the nozzles 7 after the inside of the hood 10 is filled with water from the nozzles 7 collides with the reflecting panel 3 as a strong cavitation-jet 8. Accordingly, the dirt (extraneous matter such as soot, tar or the like) of the reflecting panel 3 is washed. Sewage after washing is drained 12 under a vacuum, and sludge is coagulated and removed and reutilized. Sewage leaking from the brush 9 is recovered from a drain pipe 19 and reutilized similarly. When the washing device is manufactured in a car loading type, it works extremely efficiently.

摘要： PROBLEM TO BE SOLVED: To provide a cleaning nozzle of which the outlet opening end is easily positioned. SOLUTION: The cleaning nozzle 1' has a high pressure supply flow passage 3 and high pressure water 2 is supplied to the high pressure water supply flow passage 3 from the upstream side of the nozzle 1'. A throttle part having about 150 deg. throttle angle θ and an ejection port 5 are formed at the downstream side of the high pressure water supply flow passage 3 and after being reduced in pressure and accelerated, the high pressure water 2 is ejected from the ejecting port 5. A circular arc type hollow part 17 of a hemispherical body having a radius R of curvature is formed at the outlet of the ejecting port 5. The radius R of curvature is about 20 times the inside diameter of the ejecting port 5. A cylindrical hollow part 18 having the same diameter with that of the part 17 and a length ls is provided at the down stream side of the circular arc type hollow part 17. Further, a hemispherical outlet expanded part 19 is provided at the tip of the cylindrical hollow part 18 and plural water discharge grooves 20 are engraved radially in the radius direction on the opening end of the outlet expanded part 19.

摘要： PROBLEM TO BE SOLVED: To provide a roller type grinding apparatus always holding the maximum damping effect and capable of grinding an object up to an ultrafine powder. SOLUTION: The positional change of a roller 4 is measured by the displacement meter 40 arranged on a loading rod 10 and the frequency component of the predetermined band of the displacement of a piston 20P is taken out by a band-pass filter 41. The fluctuations of the pressure in a chamber N are measured by the pressure gauge 42 arranged to the pipeline of a cylinder device and a flow rate adjusting valve 23 and the frequency component of the predetermined band of the fluctuations of the pressure in the chamber N is taken out by a band-pass filter 43. The advance angle ϕ to the displacement of the piston 20P of the pressure fluctuations is calculated by a phase difference calculator 44. A control device 45 adjusts the opening degree of the flow rate adjusting valve 23 so that the advance angle ϕ becomes a 1/4 cycle.

摘要： PROBLEM TO BE SOLVED: To quietly and stably operate a roller mill without generating vibration even under a condition producing super-powdered coal with respect to many-kind coal operation, wide range load operation and a load rising/falling process including start/stop. SOLUTION: In a roller mill equipped with a turntable 3, the grinding race carved in the turntable and tire-shaped grinding rollers 4 to grind coal, the leading ends in the rotary direction on the bite-in side of the grining rollers are inclined toward the center axis of the turntable to form a toe-in angle and link supports being the laminated structure of coned disc springs are provided between a pressure frame and a bracket as the resistance elements to pendulum operation and water sprinkling nozzles 12 are provided in the powder layer on the turntable and inverse oil pressure is applied not only to a loading rod but also to a plunger head on an opposite side and enhanced at a time of the start or stop of the mill to cut off the connection of the loading rod 28 and the pressure frame 25 to perform grinding only by the own wt. of a grinding part.

摘要： PROBLEM TO BE SOLVED: To efficiently and quickly decompose toxic chemical substances by utilizing cavitation bubbles generated in a liquid by ultrasonic waves or the like by making catalyst coexist in a solution in a method of generating a high temperature and high pressure by a cavitation bubble generating means and decomposing chemical substances in the solution. SOLUTION: Cavitation bubbles are generated by an ultrasonic oscillation in a solution containing toxic chemical substances to decompose the toxic chemical substances. Namely H and OH radicals are generated following the generation of cavitation bubbles in the vicinity of the cavitation bubbles, and the radicals are reacted with the toxic chemical substances. When the bubbles are formed or collapsed, the temperature and pressure are risen and increased to gasify and pyrolyze or burn volatile compounds (molecular compounds). Namely both of the radical reactions and pyrolysis reaction are actuated. As the mechanism of pyrolysis generated by the cavitation bubbles is the oxidative reaction, it is desirable for the catalyst to be used to adopt an oxidation catalyst for accelerating the oxidation.
