摘要： PROBLEM TO BE SOLVED: To make it possible to superiorly perform combined use of thermoplastic resin in the principal part by allowing a δ1 alloy phase to appear in the desired region of the surface of a hot dip galvanized steel by means of blasting or grinding and then forming a fusion coating layer of thermoplastic resin via a primer layer having at least a chromating layer. SOLUTION: The chromating layer has a function of inhibiting rusting, etc., and can be converted into a surface suitable for formation of a resin coating layer as upper layer. As to the chromating layer, it is preferable to use a chromating layer of application type, which is formed by applying a required amount of treatment solution previously converted in part and then applying heating to allow conversion to promote. The resin coating layer to be formed on the primer layer is formed by fusing thermoplastic resin such as polyolefine. It is preferable to perform this fusion by the powder fusion method where a resin powder is fused by being brought into contact with the surface of an object which is heated to a temp. higher by >=100 deg.C than the melting point of the resin. This method can be applied to an internal pipe surface, a bent pipe, etc.

摘要： PURPOSE:To provide a method for effectively dispersing a small quantity of the 2nd liquid (e.g. water) in the 1st liquid (e.g. vegetable oil). CONSTITUTION:The 1st liquid flows from an opening 2a of the 1st liquid supply route 2A so as to collide with a vibrating face 1a of an ultrasonic horn 1A to apply ultrasonic vibration to the 1st liquid. Simultaneously, the 2nd liquid is fed from an opening 3a of the 2nd liquid supply route 3A near the vibrating face 1a into the 1st liquid under ultrasonic vibration at that position, made in the form of fine particles by ultrasonic vibration and delivered deliver into the 1st liquid, thus dispersibility is increased.

摘要： PURPOSE:To measure the thickness of a coating film more easily and more accurately without requiring high skillfulness. CONSTITUTION:Reflected echoes from a pipe 1 lined with a coating film 2 are measured from the outside by using the V-transmitting method of the ultrasonic angle beam flaw detecting methods. By multiplying the time lag between echoes reflected by the internal surface of the pipe 2 and those reflected by the surface of the film 2 by a coefficient peculiar to the film 2 empirically found in advance, the thickness of the film 2 is found.

摘要： PURPOSE:To make it possible to form a lining film of a desired film thickness on the corner simply in good productivity without using excess resin powder by increasing the amount of fused resin at the corner to a value larger than that at the remaining area by heating the corner to a temperature higher than that of the remaining area. CONSTITUTION:When a resin lining is applied to the rotor of a Roots blower, the rotor 1 is placed in a fluidized tank 8, and a high-frequency current is applied to an induction heating coil 9. The rotor is inductively heated and the surface temperature of the rotor 1 rises. When the surface temperature exceeds the melting temperature of the resin powder, the resin powder fluidized is brought into contact with the surface and melted by heating to form a resin layer on the rotor surface 1. Owing to the proximity effect caused by the induction heating coil 9 being the nearest to the corner 1C of the rotor 1, magnetic fluxes are concentrated on the corner 1C to raise the temperature of the corner 1C higher than that of the remaining area, so that a larger amount of resin melts and adheres to the corner 1C. Therefore, a lining film of a desired film thickness can be formed on the corner without using excess resin powder.

摘要： PURPOSE:To increase a joining strength by impressing plural electric powers having different frequencies with their time division on the same heating coil and joining dissimilar materials with their heating. CONSTITUTION:Dissimilar materials 1, 2 are arranged by interposing an adhesive 3 in the medium and an induction heating coil HC is set up at the upper part thereof. A ceramics or stainless steel is taken as the first member 1 and the dissimilar metal material to the member 1 as the 2nd member 2. The electric powers of two kinds or three kinds of frequencies having different frequency are impressed on the induction heating coil HC with their time division and after the temp. up of the member 1 and adhesive 3 upto the prescribed temp. and member 2 upto the other specific temp. they are cooled and the joining is performed. Since the joining is performed in a short time at the temp. suitable for each material the joining strength of the dissimilar materials is improved.

摘要： PROBLEM TO BE SOLVED: To keep the deviation of the thickness of a thick coating film having ≥3 mm to equal to or below an allowable level.
SOLUTION: After resin powder 14 is stuck on a previously heated bent tube 10 in a fluidization dip coating tank 13 to form an in-process coated metal strip 17, the metal strip 17 is taken out from the fluidization dip coating tank 13 to be transported to a metal strip holding pedestal 18 and kept in a stationary state for a certain time to completely melt the in-process coating film 16 by the heat of the base material 10, and the attitude of the stationary state of the metal strip 17 is turned over by the metal strip holding pedestal 18 to switch the flow direction by its own weight to the opposed direction to correct the deviation of the thickness of the in-process coating film 16 which progresses with time and is caused by the flow down by its own weight and after that, the metal strip 17 is cooled.

摘要： PURPOSE:To form a resin layer of desired film thickness on a corner section by pressing a resin layer of a plane surface section adjacent to a corner section at softening temperature or higher, creep deforming, flowing the resin to the corner section and increasing the layer thickness of the corner section. CONSTITUTION:A corner section 1C of a resin layer 10 formed by heat melting resin powder is shaped round and thin. A stopper component 11 is inserted into a through-hole 3 and its end is fixed in a position where the same projects from a rotor end surface 1B by the given distance (t). Downward pressing force is applied to press molds 12 on the upper side and downward pressing force is applied to the rotor 1 by own weight by heating a rotor 1, dissolving the resin layer 10 again, mounting flat plate-shaped press molds 12 on the upper and lower and mounting the same on a base plate 13, and the resin layer 10 on the end surfaces 1B of the rotor 1 is pressed. The press resin layer 10 is creep deformed to form a resin layer of given thickness (t) on the rotor end surface 1B, and surplus resin flows laterally to be stored in a corner section 1C and increase the thickness of the resin layer of the corner section 1C.

摘要： PURPOSE:To exactly detect the damage of the coating in a conduit by providing an electrode brought into contact with an in-conduit liquid and insulated from a conduit body, on two points separated in the longitudinal direction of the conduit, and also, providing a terminal on the conduit body, and measuring an electric characteristic between these electrodes and the terminal. CONSTITUTION:In two points A, B being at an interval in the longitudinal direction of the conduit consisting of an electric conductive conduit body 2 in which an insulating coating 1 is performed to the inside surface, electrodes 4, 5 are placed so as to bring into contact with a liquid in the conduit but so as to keep the insulation to the electric conductive conduit body 2, respectively. On the other hand, a terminal 6 is provided on a suitable position C, as well, of the electric conductive conduit body 2. In this state, electric characteristics (electric resistance, potential difference) between the electrodes 4, 5 of the two points and the terminal 6 connected to the conduit body 2 are measured. Based on this measured value, whether a damage exists in the covering 1 of the inside surface of the conduit line or not and its location are detected correctly.
