摘要： PURPOSE:To easily and inexpensively form a water repellent surface by electroless plating a base material in a plating bath made by dispersing a specific quantity of polytetrafluoroethylene particle having a specific molecular weight and specific particle diameter at a specific temp. CONSTITUTION:The base material is dipped into the plating bath made by dispersing polytetrafluoroethylene particle having 10,000-200,000 molecular weight and =125g/l blending proportion and is electroless plated at 75-95 deg.C. A nickel plating bath is preferably used as the electroless plating bath. A surfactant, particularly cationic surfactant is preferably added into the plating bath. Furthermore, sufficient stirring is preferably executed to uniformly disperse them in the non-floculated state. As a result, the water repellent film having fine surface ruggedness is formed by codepositing the polytetrafluoroethylene particle on the surface of the base material.

摘要： PURPOSE:To form a hydrophobic resin surface into high water repellency by blasting water soluble solid fine grains to the hydrophobic resin surface, forming this surface changed into a rough surface, and next by washing the solid fine grains, left in this roughed surface, removed. CONSTITUTION:By blasting water soluble solid fine grains to a hydrophobic resin surface of 0.5% or less water absorption, the surface is changed into a rough surface. Since a grindstone used in this blast processing is a water soluble fine grains, abrasive grains, left in a roughed processed surface, are easily removed only by wash. In the hydrophobic resin surface thus processed, since cone-shaped fine irregular protrusions are formed, high water repellency is displayed. In hydrophobic resin used as a processed removal surface, for instance, silicone resin, fluororsin, polyethylene, polypropylene, etc., are listed.

摘要： PROBLEM TO BE SOLVED: To provide a compact, high temperature resistant and corrosion resistant air heater exhibiting excellent corrosion resistance and durability in the highly corrosive high temperature gas atmosphere of an incinerator. SOLUTION: A ceramic outer tube 4 is mounted on a ceramic receiving metal 3 suspended by a metallic inner tube 2, a metallic outer tube 30 at the upper part of the metallic inner tube 2 and the ceramic outer tube 4 are lapped, the gap between the outer circumferential surface of the metallic outer tube 30 and the ceramic outer tube 4 is sealed by an elastic sealant 32 and the ceramic outer tube 4 is arranged to slide in the axial direction and to move in the radial direction. Since ceramic tubes having different thermal elongation/ contraction rates are sealed to move independently, they can be protected against damage due to difference of thermal deformation. When extremely lightweight ceramic tubes weak against a tensile force but strong against a compressive force are stacked in the axial direction, a long air heater can be formed and thermal energy can be recovered sufficiently.

摘要： PROBLEM TO BE SOLVED: To provide a compact, high temperature resistant and corrosion resistant air heater exhibiting excellent corrosion resistance and durability in the highly corrosive high temperature gas atmosphere of an incinerator. SOLUTION: The air heater has double tube structure of a ceramic outer tube (heat exchanger tube) 4 and a metallic inner tube 2 and it is set to utilize the features of a ceramic tube effectively. The heat exchanger tube 4 is made to have a required length for recovering required heat through single stage conduction. When the length of an element ceramic tube is short, element tubes are stacked and connected thus securing a required length as a whole. Combined weight of the ceramic tube 4 is supported by a supporting plate 3 fixed to the lower end part of the metallic inner tube 2. Since the heat exchanger tube 4 in the furnace made of ceramic is supported only at the lower end part and heating is completed by single stage conduction, a simplified air heater and thereby a compact system are obtained.

摘要： PURPOSE: To sharply reduce the sticking of ice and snow by covering the fine irregular apexes provided on the surface with the powder of an inorganic oxide applied with the hydrophobic treatment on the surface of a water-repellent resin or a film body applied with water repellency by the surface treatment of a hydrophilic resin. CONSTITUTION: A paint is applied to form a paint layer 6 on the surface of a power transmission line 1 twisted with aluminum strands on the outer periphery of a steel core, and hydrophobic fine grains 7 dispersed in an organic solvent are applied on the paint layer 6 and dried. The grains 7 are exposed on the surface of the paint layer 6 or partially submerged inside by projection during the drying to form a film body 4. The interval (s) between projections 5 on the surface of the film body 4 is 0.1-50μm, the ratio between the height (h) and the interval (s) is about 0.3-5, and the surface is formed with a water-repellent material A having the contact angle with water of 90 deg. or above. A material applied with water repellency by the surface treatment to hydrophobic silica powder, polyethylene, or a hydrophilic resin may be used for the material A. The sticking of ice and snow to the power transmission line 1 is almost prevented.

摘要： PURPOSE:To form a high-quality plating film on a large-sized material without increasing the capacity of a plating bath by separating the plating bath and a coating chamber and supplying a dispersion plating soln. in the tank to the chamber. CONSTITUTION:A plating bath 1 and a coating chamber 2 are separately provided. The dispersion plating soln. R sufficiently agitated in the bath 1 is forced under pressure into the chamber 2 by a pump 3. A large-sized material 10 is dispersion-plated in the chamber 2, and then the soln. R is returned to the bath 1. Since the agitating part of the soln. R and the coating part are separated, both parts are controlled independently and optimally, respectively.

摘要： PURPOSE:To easily perform the measurement of the tensile strength of a fragile material by using a standard tensile tester, by adhering a tough auxiliary member to the parts essentially mounted to a tester at both ends of a specimen by using an adhesive and transmitting load to the specimen through said member. CONSTITUTION:A specimen 1 is a fragile material and metal round rods 2, 3 are tough auxiliary members and adhered to both ends of the specimen 1 by using an adhesive. The upper end of the metal round rod 2 is processed so as to have a diameter slightly smaller than the inner diameter of the lower end of the specimen 1 and adhered in a state sufficiently deeply inserted in the specimen 1 and a shuckle 5 is mounted to the lower end of said rod 2 through a pin 4. The lower end of the metal round rod 3 is processed so as to have a diameter slightly smaller than the inner diameter of the upper end of the specimen 1 and adhered in a state of being sufficiently deeply inserted in the specimen 1 and the upper end of said rod 3 is fixedly clamped by a chuck 7 having a grip face 6 in order to make the fixing of the rod 3 certain. In performing a tensile test, a base stand 9 is mounted to one tensile force applying part of a tensile tester and a universal joint 8 is mounted to the other tensile force applying part and the tensile tester is operated in a usual way.
