摘要： PROBLEM TO BE SOLVED: To prevent the breakage of a conductive member during expanding and bending a joint portion. SOLUTION: Metal pipe bodies 1, 1 connected to each other via the joint portion 2 are embedded in a sheath pipe P via a filler G, the pipe bodies 1, 1 with the joint portion 2 therebetween are linked to each other via a conductor 12 so that the pipe bodies 1, 1 are conducted with each other, and a movable portion 20 is provided in the conductor 12 for allowing expansion. Thus, when the joint portion 2 is expanded and bent, the conductor 12 can be moved following the movement of the pipe body 1, and so its breakage is prevented. Around the movable portion 20, a protecting member 21 is provided which is formed of a foamed resin molding in close contact with the movable portion 20. Other portions than the movable portion 20 are covered with a protecting member 22 which is formed of a resin protecting pipe, to isolate the conductor 12 from the filler G around the pipe body 1. When the pipe body 1 and the protecting member 21 are moved relative to the filler G with the expansion of the joint portion 2, a void to the filler G therearound is secured to avoid barrier in moving the movable portion 20.

摘要： PROBLEM TO BE SOLVED: To improve productivity of a powder coating material, and dispersibility of a resin, a pigment, a curing agent and the like which are raw materials therefor.
SOLUTION: The method for producing the powder coating material comprises mixing the resin, the pigment, the curing agent and the like which are the raw materials for the powder coating material, charging the mixed product in a cavity 1a of a mold 1, and repeatedly adding a load to the mixture by punches 2 and 3 from upper and lower sides, that is, by a bulk mechanical alloying (BMA) method to disperse and mix the raw materials. A melting step by heat becomes unnecessary by dispersing the raw materials by the BMA method to enable constrained conditions of the raw materials therefor to be eliminated. Further, the amount of the curing agent is reduced to make the coating operability excellent by increasing the dispersibility of the curing agent. A low-temperature curable coating material can be designed, and a curing agent which can not be used conventionally can be used to widen the width of selection of the curing agent because the melting step becomes unnecessary.

摘要： PROBLEM TO BE SOLVED: To quickly and surely predict a softening temperature of a thermoplastic resin by calculating as efficiently as possible and simply, easily and surely evaluate a thermal property of the thermoplastic resin before synthesis.
SOLUTION: In a method for predicting the softening temperature of the thermoplastic resin with designed molecules by molecular simulation using molecular dynamics calculation, a molecular aggregation model comprises an aggregation of 300-5000 atoms having a molecular mass distribution approximated to a molecular mass distribution of the thermoplastic resin. The model is built by inputting data of the molecular mass distribution and density as an initial condition of calculation, the most stable structure in an amorphous state of the molecular aggregation model is found by the molecular dynamics calculation, a time-series change of interaction energy within and between molecules of the molecular aggregation model is found by simulation calculation using molecular dynamics when a temperature is changed in the most stable structure, and a temperature corresponding to an inflection point of an obtained energy convergence value is determined as a predicted value of the softening temperature.

摘要： PROBLEM TO BE SOLVED: To improve deposition efficiency. SOLUTION: The outside surface of a rotating pipe P is coated by spraying a coating material (a) from a gun 1. The coating material particles (a) are deposited on the nearer side from the outside surface vertically above the pipe P by inclining the spray direction of the coating material (a) to the nearer side from a spot vertically above the pipe P in the pipe rotary direction and are carried by the air flow caused by the pipe rotation to move to the tip farther side while being deposited by the particle's own weight gravity. As a result, the approach time and the approach distance of the coating material particles with the outside surface of the pipe are prolonged to be easily deposited and to improve the coating efficiency. Further, air (b) is blown from a position farther than the spray position of the coating material (a) to the outside surface of the pipe in the rotating direction. Then air flow caused by the rotation of the pipe is suppressed by the air (b) to block the flow of the coating material particles (a) carried by the air flow. As a result, the approach time of the coating material particles (a) with the outside surface of the pipe is prolonged to be easily deposited and to improve the coating efficiency.
