摘要： A heat transfer tube 1 (e.g. of circular or elliptical cross-section) intended particularly for use in heat exchangers installed in the northern hemisphere, is formed on its outer surface with at least one groove 2 inclined in a left hand screw direction. In use as a surface condenser the tube is so disposed that condensate formed on the external surface of the tube flows downwardly along said groove and the arrangement is said to induce the condensate to flow down quickly or to scatter out of the groove by the centrifugal force so as to increase the heat transfer performance of the tube. The tube outer surface may have additionally, longitudinal grooves (e.g. 6, 7, Figs. 5a, 5b), which interconnect inclined grooves, and also a large number of fine grooves.

摘要： A process for the treatment of soil(s) and/or industrial waste solids involves press-moulding. Starting materials of controlled different particle size are mixed in order to obtain an optimum compact structure, while eliminating agglomerated structures in the mixture and small quantities of slaked lime and cement and/or sodium silicate as binders are also added. Mixing of the materials is effected by means of a mixer equipped with rollers for a sufficient period of time and then press-moulding is effected in a mould equipped with perforations for drainage under evacuation, thereby obtaining moulded articles such as building blocks.

摘要： PROBLEM TO BE SOLVED: To provide a method for growing lithium borate single crystals that can prevent fast sticking of a crucible to a grown crystal to afford a lithium borate single crystal of good quality in a good yield. SOLUTION: The inner surface of a crucible 4 made of graphite within the range of the tip of the crucible 4 to 1-5 cm below the top surface A of a raw material melt is covered with a metallic foil 40 such as platinum and a raw material for the lithium borate is then placed therein. The raw material is then heated with a heater 6 to provide a raw material melt 3 for the lithium borate. The melt is moved through the interior of a furnace core tube 7 to the side of a low temperature and slowly solidified to thereby grow the lithium borate single crystal 1. The platinum is platinum, platinum rhodium, etc. When the crystal growth is completed, the metallic foil 40 is lifted to take out the grown crystal from the crucible 4 with the metallic foil 40 and all. The metallic foil 40 is subsequently removed to provide the lithium borate single crystal 1.

摘要： PROBLEM TO BE SOLVED: To provide an organic wastewater treatment apparatus having high wastewater treatment performance in comparison with the installation surface area and the water tank capacity. SOLUTION: This organic wastewater treatment apparatus comprises a contactor 6 bearing microbe which decomposes contaminating substances in a raw water adjusting tank 5 and, in the tank 5, raw water L is pre-treated. In the case the water level of the wastewater lowers and the upper part of the contactor 6 is exposed, wastewater is sprinkled by a sprinkling apparatus 9. Moreover, air is supplied from a lower side of the contactor 6 and propagation of the microbe carried on the contactor can be heightened.
