  • Patent number: 8333457
    Abstract: The present invention is used for a printing target having a non-flat surface portion in at least a portion of a printing surface. To form a decorative printing film on the printing surface of a base material, ink droplets of the same color as the color of the printing film are ejected from nozzles of an inkjet printer onto the printing surface. The distance from the nozzles to the printing surface is represented by X (mm). The droplet amount of the ink is represented by Y (pl). When the maximum value of the distance X is greater than 5 mm, the droplets are ejected from the nozzles each by an amount greater than the droplet amount Y represented by the equation: Y=0.9X1.5.

  • Patent number: 7935293
    Abstract: An injection molding apparatus includes a forming mold provided with a gas inlet through which a gas is introduced into an area between a rear molding surface in a cavity and a resin material inside the cavity. A plurality of the gas inlets is provided along a passage direction of the resin material in the cavity. In injection molding the resin molded article, a molten resin material is introduced into the cavity from a resin inlet and, when filling the inside of the cavity with the resin material, the introduction of the gas is sequentially started, beginning with a gas inlet provided in an area inside the cavity which is first filled with the resin material, thereby sequentially pressing the relevant resin material against a front molding surface of the cavity.

  • Patent number: 7841670
    Abstract: The degree of freedom in design is increased while maintaining strength by enabling a decorative member to be disposed without thinning a wheel main body. A wheel is made up of a wheel main body 1 which is made up of a rim portion 10 and a disc portion 11 and which has a vent hole 141 in the disc portion 11 and a decorative member 2 made from a resin which is held in at least the disc portion 11 and is observed from the vent hole 141. Since the decorative member 2 is observed in the vent hole 141, the wheel main body 1 including spoke portions 14 does not have to be thinned. In addition, since the design of the decorative member is observed in cooperation with the design of the disc portion 11, the degree of freedom in design is increased.

  • Patent number: 7497509
    Abstract: A fender liner includes a surface layer serving as the outermost layer and an inner layer located between the surface layer and the outer surface of a wheel well. The surface layer and the inner layer are formed of nonwoven fabric. The nonwoven fabric forming the inner layer has a higher tensile strength than that of the nonwoven fabric forming the surface layer. Accordingly, the fender liner has a favorable noise reduction capability, and has a sufficient rigidity to bear a weight increase due to water absorption. Alternatively, the nonwoven fabric forming the surface layer may have a higher bulk specific gravity and a smaller fiber diameter than those of the nonwoven fabric forming the inner layer. In this case, the noise reduction capability and the durability are both improved.
