摘要： PROBLEM TO BE SOLVED: To prevent or reduce heat shrinkage of a resin material in a circumferential direction when the resin material which contains reinforcing fibers such as glass fibers is molded into a tubular shape by blow molding, by orienting the reinforcing fibers added to the resin material along the circumferential direction of a tubular molding. SOLUTION: In a resin product 4 molded by blow molding, all glass fibers 6 are oriented along the circumferential direction. In this case, as each glass fiber 6 displays an opposing force against a force to shrink, heat shrinkage of the resin product 4 in the circumferential direction hardly generates even under an atmosphere of high temperature, so that the inner diameter of the resin product 4 is not changed by heat shrinkage. Accordingly, a blow molding can be used also at a part where using of it has been difficult in fear of dimensional change due to heat shrinkage, thereby widening the scope of application of resin products.

摘要： PROBLEM TO BE SOLVED: To appropriately and efficiently plot the pattern having desired colora tion by preventing the pattern plotted on a face to be plotted from being greatly different from that originally intended by the influence of coloration on the pattern formed on the face even if the coloration of the face is other than white. SOLUTION: This plotting coater is provided with a coating gun 4 having plural plotting nozzles 4a to 4d for discharge ink paints of plural colors on a face 7 to be plotted and a means for moving the gun 4 in the specified x direction and in the crossing y direction and further provided with an undercoating nozzle 5 shifted in position from the nozzles 4a to 4d at least in the x or y direction. The undercoating nozzle 5 is moved to the position opposed to the plotting area of the face 7 preceding the nozzles 4a to 4d to discharge the undercoating ink paint on the area.
