摘要： PROBLEM TO BE SOLVED: To provide a method for producing a new powdery crosslinked fluorine resin and capable of efficiently obtaining the powdery crosslinked fluorine resin of high quality having a uniform particle size at a low cost. SOLUTION: This production of a powdery crosslinked fluorine resin is to keep a powdery unbridged fluorine resin at a temperature equal to or more than its melting point in a low oxygen atmosphere, forcibly float the powdery resin in a separated state by the gas flow of the low oxygen atmosphere and irradiate the resin with radioactive rays to carry out the crosslinking treatment. Thus, the powdery unbridged fluorine resin is treated in isolated particle units to crosslink by the radioactive rays, the powdery crosslinked fluorine resin of high quality having a uniform particle size can be effectively produced.

摘要： PROBLEM TO BE SOLVED: To perform the stable mass-production of cold water close to 0 deg.C at a low price. SOLUTION: Water 15 to be cooled is fed from a water ejection port 9 into a container 1, ice grain 16 is fed from an ice grain feed device 13, the turning flow 14 is formed in the container 1 using the jet flow of water 15 to be cooled, and the mixed liquid of water 15 to be cooled and ice grain 16 is generated. The mixed liquid is circulated in the container 1 through a static mixer 5, and ice grain is melted at two parts in the container 1 and the static mixer 5 to make cold water. When the temperature of cold water to be extracted from the static mixer 5 reaches close to 0 deg.C, a valve 6 is opened to take cold water to the load side. Melting of ice grain is greatly promoted, and cold water of large volume close to 0 deg.C can be continuously and stably manufactured.

摘要： PROBLEM TO BE SOLVED: To prevent the putrefaction of a water soluble cutting oil, and mix copper with the water soluble cutting oil safely and properly. SOLUTION: Water soluble cutting oil 1a liable to propagate microorganisms and bacteria is circulated in a passage from a liquid tank 1 to an electrode storage tank 2 via an oil pump 6, and returned to the liquid tank 11. Copper electrodes 3 housed in the electrode storage tank 2 exist in the circulation passage and electric power is supplied from a control part 16 across the electrodes 3, according to a power supply time determined on the basis of the concentration of copper, and the type and quantity of a liquid-state medium. As a result of electrolysis taking place due to the supply of the electric power, the copper is dissolved from the electrodes 3 and mixed with the water soluble cutting oil 11a, thus sterilizing the water soluble cutting oil 11a and preventing the putrefaction thereof.

摘要： PROBLEM TO BE SOLVED: To ensure good heat transfer properties and wetting properties of an absorption solution as well as high heat transfer efficiency by forming an acute angle between the side of a corrugated fin and an internal wall surface of a pipe to be processed, and further forming a spiral groove having a wedge shaped cross section. SOLUTION: There are provided a fin 3 which is formed into a spiral shape along an internal wall surface 2 of a pipe 1 to be processed and has a corrugated shape in the spiral direction, and a spiral groove 4 that forms a wedge shaped cross section with the internal wall surface 2 and the side of the fin 3. The fin 3 has a predetermined inclination angle with respect to the internal wall surface 2. An absorption solution is stirred with the corrugated fin 3 upon its flowing along the spiral groove 4, and the stirring action is produced owing to a change in a flow passage cross section in the spiral direction owing to the corrugated shape of the fin 3, and hereby absorption capability of heat is improved. Accordingly, there are ensured excellent heat transfer properties and good wetting properties of the asorption solution together with high heat transfer efficiency.

摘要： PURPOSE:To expand heat transfer tubes and tightly adhere these tubes to external heat transfer members by inserting the heat transfer tubes hermetically sealed at both ends in the state of the sealing water existing therein into holes worked to the external heat conductive members and evaporating the sealed water by heating. CONSTITUTION:While the rupture pressure by the internal pressure of copper tubes with spiral grooves on the inside surfaces having, for example, 9.52mm and 0.34mm min. thickness is over 16MPa at ordinary temp. the rupture pressure is dropped to about 10MPa much lower than the mentioned above pressure by the softening of copper blank materials at 300 deg.C and the satd. steam of the water at the same temp. is increased to the same value in the case of use of the mentioned above copper tubes as the heat transfer tubes 1. The required value is obtd. without rupturing the copper tubes if the heating temp. near the mentioned above temp. is precisely controlled. Then, the heat transfer tubes 1 are expanded and are tightly fitted to fins 2 without degrading the performance of the high-performance heat transfer surfaces previously worked within the heat transfer tubes 1 and the high-performance heat exchanger is produced with high efficiency at a low cost.

摘要： PURPOSE:To reduce cost and energy loss by actuating a heat pipe with hot water after heat exchange, and melting snow with the heat pipe, while introduceing the hot air from a hot air generator to a hot air snowmelt duct for melting snow around a railway branch section. CONSTITUTION:The hot air generated by a hot air generator 5 is introduced to a hot air snowmelt duct 8 via an air duct 7, thereby melting snow around a railway branch section. On the other hand, a metal tube coil is wound around the external surface of the combustion cylinder 6 of the hot air generator 5, or a heat exchange section having a metal water circulation jacket is provided, thereby forming a hot water generator 9. In addition, the hot air from the combustion cylinder 6 is introduced to a snowmelt duct 8 via connection to the air duct 7. Furthermore, hot water generated at a hot water generation section 9 is introduced to a buffer tank 10 and hot water is pertinently supplied from the tank 10 to a hot water pipe 4, thereby heating the heating head of a heat pipe 3 laid at the railway branch section for snow melting. According to the aforesaid construction, both hot air and hot water systems can be actuated in combination by a single heat source to enable cost to be reduced and maintenance work to be simplified.

摘要： PURPOSE:To unify heat transfer performance in the lengthwide direction of a heat transfer tube by a method wherein two rows or more of heat transfer tubes for promoting the operation of operating liquid in the upper or lower part of a system are arranged and one part of the tubes is used as going tubes while remaining tubes are used as returning tubes. CONSTITUTION:Upper heat transfer tubes are arranged in two rows 3a1, 3a2 and lower heat transfer tubes are arranged in two rows 3c1, 3c2 while one end of the tubes is turned to use the heat transfer tubes in the row 3a1 as a going tube and use the other heat transfer tube in the row 3a2 as a returning tube. The uneven property of performances at the inlet side and the outlet side of the heat transfer tube is improved remarkably and unified heat transfer performance may be shown along the whole length of the heat transfer tube. As a result, the adhering degree of ice upon space cooling operation is equalized in the lengthwise direction of the heat transfer tube, whereby ice 6 may be frozen with the same growing speed along the whole length of the tube. The same thing may be said in space heating operation.
