摘要： PURPOSE:To provide excellent cleaning effect without using a solvent which possibly pollutes environments by installing a cleaning container which can be kept vacuum, a vacuum-evacuating means for the cleaning container, a circulating and supplying means to recover a cleaning liquid and supply the cleaning liquid again, and a circulating fan to forcibly circulate the ambient gas. CONSTITUTION:A cleaning apparatus is provided with a cleaning container 2 in which articles 1 to be cleaned are put and the inside of which can be kept vacuum, a vacuum- evacuating means 3 to make the cleaning container 2 vacuum, a cleaning liquid circulating and supplying means 4 to supply a cleaning liquid to the cleaning container 2 and at the same time to recover the cleaning liquid from the cleaning container 2 and supply it again, and a circulating fan 20 to forcibly circulate the ambient gas in the cleaning container 2. The staining components adhering to the articles 1 to be cleaned are washed out and dissolved and thus the articles are cleaned by spraying the cleaning liquid to the articles 1 to be cleaned through a cleaning nozzle 5 and the remaining cleaning liquid adhering to the articles 1 to be cleaned are quickly evaporated and vacuum drying is carried out by making the cleaning container 2 vacuum after the cleaning.

摘要： PURPOSE:To produce direct heat exchange and enhance the efficiency of gas cooling by installing metal-made heat transfer plates inside a vessel main body in a radiating fashion and allowing gas and cold water to flow in the clearance between the heat transfer plates. CONSTITUTION:A vessel main body 2 whose upper part 3 and bottom are connected with a flange 5 where the wall surface of the upper part 3 is under water cooled double structure and a high temperature gas flow inlet is installed to the central upper part of the vessel main body 2. A large number of heat transfer boards 1 comprising metal thin sheets are mounted inside the vessel main body 2 in a radial fashion, centering on a support column 20. On the other hand, there are installed cooling water spray nozzles 10 and 11 on the upper part of the vessel main body 2 where cooling water is sprayed from here. The cooling water and the high temperature gas introduced from the flow inlet 6 drop through the clearance between the heat transfer boards 1. During the drop there takes place direct heat exchange between the gas and cooling water whereas indirect heat exchange takes place between them by way of the heat transfer boards 1. Both the gas and water after heat exchanged are taken out from the bottom 4 respectively.

摘要： PURPOSE:To enhance cooling efficiency of a work after a heat treatment is finished and to eliminate a cooling irregularity by providing a vent passage, and tiltably providing a nozzle for diffusing cooling gas into a heating chamber through an opening so as to vary a diffusing direction. CONSTITUTION:Nozzles 41, 41 of length substantially over the entire length of an opening 26 of vent passages 40, 40 are associated. Shafts 41 are coupled to both ends of the nozzles 41, supported rotatably to bearings 43, one shaft 42 is connected with a lever 44 to be reciprocated by a drive source such as an air cylinder, etc., through a link, and the nozzle 41 is tilted in both directions in a range of the tilting angle theta by the reciprocation of the lever 44. The angle thetais so set as to generally cover about the half of the area of a work zone 30. Thus, its cooling efficiency can be improved, and hence a cooling time can be shortened, and cooling irregularity can be eliminated.

摘要： PURPOSE:To contrive the shortening of cooling time and the elimination of the variability of cooling by a method wherein cooling gas ventilating passages are arranged opposingly at both sides in the vicinity of an opening provided in a heating chamber nozzles, blowing cooling gas into a heating chamber through the opening, are provided in the ventilating passages. CONSTITUTION:A furnace body 20 is provided with ventilating passages 40, 40 of cooling gas, at the bottom of the furnace body 20 while the ventilating passages 40 are arranged opposingly at positions avoiding sideward from the positions immediately below the opening or both sides of the vicinity of the opening 28 so as not to preclude the elevation of a door 30, opening and/or closing the opening 28. A multitude of nozzles 41, whose tip ends are faced upward obliquely, are provided in respective ventilating passages 40 so as to form one row with proper intervals while cooling gas, sent into the ventilating passages 40 is blown out of the nozzles 41 upward obliquely. The cooling gas, blown out of the nozzles, is blown into a heating chamber 22 through the opening 28 under a condition being intersected to each other and is blown against works, received in a work zone 33, from the lower side of them.

摘要： PURPOSE:To remarkably improve the quality of a material to be treated and also to shorten treating time by perfectly replacing atmosphere for the material inside an inner cover with inert gas at the time of annealing the coiled material to be treated. CONSTITUTION:At the time of annealing the cold-rolled coiled material 1 to be treated, the material is put on a base plate, and the inner cover 3 is covered and a vacuum chamber 11 for vacuum suction is covered on this. Prior to heating, after evacuating the air in and out of the inner cover with a vacuum pump 19 mounted on the vacuum chamber for replacing gas in the furnace at the same time, the inert gas is filled up in the vacuum chamber till arriving to the atmosphere. Then, the vacuum chamber is removed and instead of this, by covering the heating cover, heating is executed.

摘要： PURPOSE:To easily and accurately measure heat conductivity by determining the function showing the relation between the upper surface temp. and heat conductivity of a sample from a measured value and calculating the heat conductivity at arbitrary measuring temp. on the basis of said function by operation. CONSTITUTION:In such a state that the under surface temp. To of a sample is held to constant temp. sufficiently lower than measuring temp. T, the upper surface temp. Tm of the sample is set to temp. sufficiently higher than the under surface temp. To and successively altered to measure the heat conductivities lambdam of the sample in the respective states two or more times and, from these measured values, the function showing the relation between the upper surface temp. Tm and heat conductivity lambdam of the sample in such a state that the under surface temp. To of the sample is kept constant is determined and, on the basis of said function, the heat conductivity lambda in such a state that the internal temp. of the sample is the measuring temp. T is calculated by operation. By this method, the heat conductivity lambda of the sample can be measured easily and accurately.
