Title: Moving type electrolytic decontamination device
Inventor: SUZUKI TAKEO
IPC: G21F9/00
Filed: 1987-05-29
Abstract: PURPOSE:To stabilize a decontamination operation by fitting annular packings and electrode pipes into grooves provided around a recess of a main body in such a manner that the front ends thereof are extended and are energized forward. CONSTITUTION:Plural compression springs 48 and the packings 49 having an annular shape are mounted in the grooves 46. The packings 49 are held energized forward by the elastic force of the compression springs 48 and are normally held engaged by suitable members in the positions where the front ends thereof extend from the main body 39. To decontaminate the wall surface 57a of an object 57 to be decontaminated, an operator turns on the main switch of a control panel 26 to bring the front part of the main body 39 into pressurized contact with the wall surface 57a of the object 57. An electrode ring 52 retreats into the body 39 to close an internal switch 56 at this time. An electromagnetic valve 29 is thereby opened and a pump 27 is operated to deliver an electrolyte to a recess 41. The electrolyte 23 is brought into contact with the wall surface 57a while an electrode 45 as a positive electrode and the electrode ring 52 as a negative electrode are kept energized. The contaminant sticking to the wall surface 57a is then electrolyzed. The wall surface is thus decontaminated.

Filed: 1985-06-19
Abstract: PURPOSE:To obtain thoroughly continuous penetration beads by controlling the supplying conditions of a welding wire and the moving condition of objects to be welded according to the state of forming the penetration beads. CONSTITUTION:A computer 23 recognizes the position at a butt joint 20 just before the start of penetration root pass as a pass joint position by monitoring of a pulse generator 22. The computer 23 compands the temporary stop of rotation, selects the temporary feed stop of a filler wire 26, the temporary stop of oscillation and the adequate value of the welding current according to the joint diameter from the preliminarily stored signals and outputs the same to a welding control device 28.

Abstract: PURPOSE:To make a dust collecting equipment capable of treating the waste gas quantity optimum against variation of gas temperature, by measuring the flow rate or flow speed of the outside air with a measuring tube provided to the vicinity of the outside air sucking position of a sucking part, and controlling automatically the flow rate of an exhausting gas so that the measured value coincides with a set value. CONSTITUTION:The flow rate or flow speed of the outside air, passing through the inside of a small-sized tubular measuring tube 9 which is communicated to the atmosphere and provided to a gap 3 (outside air sucking position) of a hood 2, is measured by measuring instruments 10. The number of revolutions of a motor 11 for driving an exhaust fan is controlled by a speed controlling device 12 so that the measured flow rate coincides with a set flow rate. As the air is sucked through the gap 3 of a equipment 1, the flow rate of the air is decided by the pressure difference between the internal and external pressures. Then the flow rate or flow speed in the tube 9 can be used as a representative value of sucking quantity by providing the small-sided measuring tube 9 as a new gap to the vicinity of the gap 3 of the hood 2.

Abstract: PURPOSE:To improve the condensing heat transfer efficiency of the captioned heat transfer pipe by a method wherein a spiral fine groove and a spiral rising are provided on the inner wall surface of the heat transfer pipe and a plurality of streak- like wet-proof sections which do not get wet from a condensed liquid are provided over the groove and the rising so as to intersect the latters. CONSTITUTION:The spiral groove 2 having a number of closely spaced continuous turhns and the rising 3 separating the turns of the groove are formed on the inner wall surface of the condensing heat transfer pipe 1. Further, the streak-like and wet-proof sections 4 which do not get wet from the condensed liquid are provided over the groove and the rising in the longitudinal direction of the pipe 1. For the formation of the wet-proof sections 4, a coating of an ethylene tetrafluoride or a noble metal plating or the like is utilized. With the above structure, a film of the liquid formed on the surface of the rising 3 as a result of condensation of the liquid flows into the groove due to the surface tension of the liquid and is splashed by the liquid cutting action of a stream of liquid vapor at each of the wet-proof sections 4 so that the liquid becomes drops. Thus, the heat transfer surface of the pipe 1 which is effective for the condensation of the liquid is always subjected to the liquid vapor and therefore, the heat transfer efficiency of the pipe can be improved.
