摘要： PURPOSE:To improve the sensitivity and reproducibility of an analytical apparatus of atomic absorption by simple constitution, by heating a disperser scattering a sample mist in an atomizing room. CONSTITUTION:A capillary tube 4 introducing a sample solution is inserted into the rear part of an atomizing room 3 of an atomizer 1 providing a burner 2 atomizing a sample molecule by thermal dissociation at the tip end part and a combustion improver feed pipe 5 for turning the sample solution into a mist and sending into the room 3, is provided around this tube 4. A metallic disperser 6 scattering the sample mist is provided in front of an exit of the tube 4 and this disperser 6 is provided with a heater 7 for heating the disperser 6. A combustible agent feed opening 8 and a drain discharge opening 9 are provided on a wall of the atomizer 1 at the upper and lower positions of the disperser 6. A conventional atomizer is used without greatly reconstructing it because the sample mist is atomized by heating the disperser 6 in the room 3 by the heater 7 and the solvent is vaporized by heating the sample.

摘要： PURPOSE:To improve adhesion between a filler metal and resin by a method wherein the filler metal used when organic high molecular synthetic resin is injected into a mold is surface-treated in advance by plating a material containing an organic high molecular material. CONSTITUTION:The surface of the filler metal 3 is plated 5 by plating solution where organic high molecular material (hereafter referred to as high molecular grains) 4 is added to create plated layer 5 containing high molecular grains 4 on the surface of the filler metal 3. Then, organic high molecular synthetic resin 1 is injected. Since high molecular grains 4b or 4d is bridged inspite of the existence of oxide coating 2, the adhesion between high molecular grains 4 and injected resin 1 is especially excellent and the adhesion between the filler metal 3 and plating 5 is also strong. Thus, when the surface is treated by the plating solution containing organic high molecular material in the filler metal, adhesion between the organic high molecular resin molded product and the resin can be increased remarkably.

摘要： PURPOSE:To obtain a heat radiating body surface with a high heat conductivity by a method wherein an anode oxide film is formed on an Al-main material surface, which is engraved through its pores, concerning the heat radiating body with a surface treated layer of a high heat conductivity used for ebullition cooling. CONSTITUTION:When an Al-main material 1 is immersed in a mixed solution of sulfuric acid, chromic acid, phosphoric acid, etc. or 2 kinds of the acids to form an anode oxide film, Al is dissolved in an electrolyte to form a porous film. When an active layer 4 and a ground metal 1 are engraved through a pore 31 of the porous film after that, a cavity 2 is made to gain a surface condition with a high heat- transfer.

摘要： PURPOSE:To form cavities in the heat radiating surface of a heat radiating body and improve boiling characteristics by applying chrome plating on the surface of said body then subjecting the same to electrolytic etching and liquid honing. CONSTITUTION:A heat radiating body 2 made of copper or the like as a base material is immersed in a chrome plating soln., whereby a chrome plating film having numerous fine cracks 4 in the heat radiating surface is formed. Thence, the circumferences of the cracks 4 and small pores are enlarged by electrolytic etching into a porous state 5, and further the connecting fine cracks 4 are shaped off by liquid honing treatment, whereby the points of intersection of the cracks 4 with the other cracks 4 are left as cavities 6. The cavities 6 is easily formed in the heat radiating surface of the heat radiating body 2 by this treatment, and the heat radiating body of improved boiling characteristics and high heat conductivity is obtained.

摘要： PURPOSE:To simply provide a radiation surface having cavities to enhance boiling property by a method wherein a plating solution containing a dispersing agent of specific size is used to plate the surface of a radiator to provide a plated film having part of the dispersing agent exposed, then the dispersing agent is dissolved out. CONSTITUTION:The surface of a radiator 1 is cleaned with alkaline degreasing or picking, is immersed in a plating solution containing a dispersing agent, and is applied with plating while stirring with air to form a plated film 2 in which the dispersing agent 3 is distributed. Then, a proper solvent is used to dissolve a part of the dispersing agent 3 exposed from the plated film 2 thereby forming cavities 4a- 4d on the radiating surface. Among the cavities, ones shown by 4a-4c are ideal shape having narrow openings. Most appropritate dispersing agent 3 includes an organic high polymer such as epoxy resin and nylon.

摘要： PURPOSE:to inexpensively form the heat radiating face having the figure of a constant cavity on the surface of heat radiating body and superior thermal conductivity, by forming plural number of minute paint islands on the heat radiating face of the heat radiating body and removing the paint after plating the heat radiating face. CONSTITUTION:Plural number of the minute islands 3 are formed by sticking the paint on the heat radiating face 1a of the heat radiating body 1. The above-mentioned islands 3 are formed by sticking the paint by contacting the plate having plural number of minute pores which are perforated at a fixed interval on the surface of the body 1. After that, the body 1 is plated and the plating coat 4 is formed. Next, the paint on the islands 3 is dissolved and removed and then, the cavity 5 having a uniform figure, is easily obtained. Thus, the heat radiating face having a superior boiling thermal conductivity, is inexpensively formed on the surface of the body 1 without carrying out mechanical processing by the usual method.
