摘要： PROBLEM TO BE SOLVED: To provide an outdoor air treating device never sparking due to the short circuit between the collecting electrode and discharge electrode. SOLUTION: The snow and fog collected by a dust collecting plate 18 is converted to a waterdrop and dropped from the plate 18. At this time, the waterdrop falling along the vertical face 31 of a guide plate 26 is dropped vertically from a second drip 32, and the particles of snow and fog collected at the upper part of the slope of the collecting plate 18 are dropped along the slope 36. The particles of snow and fog falling along the slope 36 are surely dripped by the second drip 32 and dropped vertically. As a result, contact of the waterdrop falling from the collecting plate 18 with a horizontal rod 12 is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a cleaner by which dust stuck on the inner wall surface of an air-conditioning duct is surely removed. SOLUTION: This air-conditioning duct cleaner 10 is constituted of a cleaning part 14, a leg part 16 and a dust collecting part 18. On using it, the whole cleaner is inserted into a duct 12 with the leg part 16 being folded up. Next, the leg part 16 is opened in umbrella to a main axis 24 to abut and support it on the inner wall surface of the duct 12 and to fix the whole cleaner in a prescribed position. Then, when compressed air is fed to an air motor 20 of the cleaning part 14 to rotate the air motor, an air hose 22 connected to an air diffuser of the air motor 20 is also rotated with it to blow out compressed air while striking the inner wall surface. In this way, dust stuck on the inner wall surface of the duct 12 is removed by double removal action of the impact due to striking of the air hose 22 and the compressed air.

摘要： PROBLEM TO BE SOLVED: To perform an effective insulation of an electrical discharging electrode supporting part and further to enable a stable operation of a surrounding air processing device to be carried out. SOLUTION: An electrical discharging electrode 20 of an electrostatic charging device 14 is supported on an insulator 30 formed in a hollow shape. A part of fresh air passed through the electrostatic charging device 14, a filter 16 and a heating/cooling device 18 is blown by a fan 42 into the insulator 30 and supplied. The air supplied into the insulator 30 is heated by a heater 44 and the insulator 30 is heated by supplied heated air. Accordingly, even if moisture such as fog or snow or the like is adhered to the insulator 30, the adhered moisture can be dried, so that the supporting part for the electrical discharging electrode 20 can always keep its dried state. With such an arrangement as above, the supporting part for the electrical discharging electrode 20 is always insulated against a ground part.

摘要： PURPOSE: To apply optimum pulse charging voltage according to dust properties by controlling pulse output of a pulse power source of a pulse charging electric precipitator of the prestage or DC base current of a DC base power source so that a DC voltage value of a moving electrode electric precipitator of the poststage can be lowered. CONSTITUTION: DC voltage applied to a moving electrode electric precipitation part 20 from a DC power source 22 is detected by a voltage detecting part 23 to output it to a pulse power source control circuit 15. The pulse power source control circuit 15 controls a DC base power source 12 and a pulse voltage generator 13 based on this signal so that the detected DC voltage value of the moving electrode electric precipitator 20 can be lowered. That is, by charging conditions of a pulse charging electric precipitation part 10 of the prestage, dust collecting performance of the moving electrode electric precipitation part 20 is changed. Thus optimum pulse charging operation is performed.

摘要： PURPOSE: To provide an electrostatic precipitator in which collected snow is surely molten to turn it into water in a dust collector, which is easily discharged. CONSTITUTION: A dust collecting electrode frame 20 constituting a dust collecting electrode 16 is constituted by connecting pipes 28 and high temperature fluid is passed through the pipes 28 and also projection lines 32 are made obliquely on dust collecting plates 26 provided on the dust collecting electrode frame 20. In this way, snow collected on the dust collecting plates 26 does not directly fall downward but falls along the inclined projection lines 32. Since the snow falling along the projection lines 32 falls while approaching the dust collecting electrode frame 20 in which high temperature fluid flows, it is gradually molten during falling, and when it is discharged to a drain groove 44, it is completely molten and is discharged as droplets.

摘要： PURPOSE:To eliminate a difference in adhering amounts of a scale and a slime at input and output sides of a heat exchanging tube and to increase the service life of a heat exchanging tube by rotating a partition wall plate in the case of heat exchanging and inverting a flowing direction in the tube. CONSTITUTION:A motor 44 is operated in a heat exchanging operation to rotate a partition wall plate 14. Thus, when a communication hole 38 formed at the plate 14 is moved to a position of an input chamber 20A, a communication hole 40 is disposed at an output chamber 20B. On the contrary, when the hole 38 is disposed at the chamber 20B, the hole 40 is disposed at the chamber 20A. That is, the plate 14 is rotated thereby to alternately switch an input side and an output side of a heat exchanging tube 36. Accordingly, since a flowing direction of heat source fluid 21 flowing in the tube 36 is periodically inverted, a difference of adhering amounts of scale, slime at the input side and the output side of the tube 36 can be eliminated. Further, since a back washing effect is generated, the scale, etc., adhered in the tube 36 can be reduced.

摘要： PURPOSE:To calculate a parking charge by correctly collating an entry vehicle and a leaving vehicle even when the character of a number plate can not be recognized owing to soiling. CONSTITUTION:The vehicle 16 passing through an entry path is image-picked-up by a TV camera 20 to measure the height and the width of it by an ultrasonic sensor. A vehicle number code preparation device 24 extracts character information of the number plate and vehicle height/width information, gives a vehicle number code for each entry vehicle 16 and stores the vehicle number code in CPU 28 with its every time. Next, a vehicle passing through a going-out path is image-picked-up with a TV camera to measure the height and the width of it by an ultrasonic sensor. A vehicle number code preparation device 32 extracts character information of the number plate and vehicle height/width information and gives a vehicle number code and each going-out vehicle. Every time of this, a corresponding vehicle number code is retrieved from the vehicle number code of the entry vehicle stored in CPU 28 based on the vehicle number code given to the going-out vehicle to calculate a parking lot using time from the entry time stored with the retrieved vehicle number code and a present time to calculate the parking charge.
