  • Patent number: 5211893
    Abstract: The method for molding a resin reinforced with fiber wherein a resin sheet reinforced with fiber is positioned juxtaposed a face of a mold, which is either one of a female mold or a male mold, and then hardened, but before molding, modifying the viscosity to different levels in different portions of the resin sheet. Thus, it is possible to surely prevent occurrence of a partial difference in thickness of the moldings or, if necessary, to partially change these thicknesses according to predetermined values.

  • Patent number: 4733746
    Abstract: A vacuum treating method and apparatus wherein preliminary vacuum chambers which are charged with and discharged therefrom materials to be treated are arranged on both sides of a vacuum treating chamber such that the preliminary vacuum chambers are switchingly communicated with and disconnected from the vacuum treating chamber; the materials are alternately moved between both the preliminary vacuum chambers and the vacuum treating chamber and are subject to vacuum treatment for a predetermined period of time in the vacuum treatment for a predetermined period of time in the vacuum treating chamber; wherein when a material to be treated has been charged from one preliminary vacuum chamber to the vacuum treating chamber and a treated materiala has been discharged from the vacuum treating chamber to the other preliminary chamber, the vacuum treating chamber and both the preliminary vacuum chambers are disconnected from each other, then the pressure within the vacuum treating chamber is reduced to a required degre

  • Patent number: 4724057
    Abstract: The surface of a product molded of polyolefin is washed with a fluorine-containing organic solvent such as CCl.sub.2 F--CCl.sub.2 F or CCl.sub.2 F--CClF.sub.2 and, thereafter, the product surface is treated with a plasma. Since the product surface is washed with an organic solvent containing fluorine, wastewater and process operation can be controlled with relative ease. A painted product pretreated by the process of the invention has a high peel strength and water resistance.

  • Patent number: 4623190
    Abstract: A front fender for an automobile molded of a synthetic resin in a manner to provide an even flow of the resin to all portions of the fender in order to avoid points of weakness within the fender. The flow starts from numerous points along the fender arched wheel opening and eventually flows through a groove extending to the most radically remote portion of the fender to ensure flow thereto. Thickened cross-sections are formed along the arched wheel opening and the vertical rear edge of the fender for strength and impact resistance.

  • Patent number: 4578281
    Abstract: A partial painting method suitable for partially painting a workpiece or article of a complex surface shape. A surface of the workpiece is coated with strippable paint. The coated strippable paint is dried into a strippable film on the workpiece surface. A laser beam is applied to the strippable film along a prescribed cutting line so as to cut the strippable film. A portion of the strippable film corresponding to a first area of the workpiece surface to be painted is peeled off, while the remaining portion of the strippable film is left adhering on a second area of the workpiece surface to remain unpainted, and thereby masking of the workpiece is completed. The first area is then painted with a paint to form a final paint coating.

  • Patent number: 4564232
    Abstract: An automobile door with an inner plate and an outer plate wherein the outer plate has a panel formed from a synthetic resin. The panel is attached to a rigid metallic plate, such as steel, through a plurality of fastening holes formed in the longitudinal direction of the synthetic panel. One of the fastening holes near the forward end of the panel has a diameter substantially that of the fastening means. The remaining fastening holes are formed so as to allow longitudinal expansion and contraction of the synthetic panel. A lip portion is formed near the lower edge of the synthetic panel to engage with the inner plate of the door.

  • Patent number: 4098184
    Abstract: A method for printing designs, patterns, characters, letters, and other desired images on an object having a convex or raised surface, wherein the images to be transferred onto the object is first carried on a flexible image carrier, then this flexible image carrying medium is disposed in a mutually opposed relationship with the object to be printed at a predetermined space interval provided therebetween, thereafter the flexible image carrying medium is caused to expand or bulge out toward the raised surface of the object to be printed by a fluid pressure to act on the flexible medium from one side thereof opposite to that where the image is carried, while controlling a degree of expansion of the flexible image carrying medium is controlled by a restrictive frame for the flexible image carrying medium to attain an intimate contact between the flexible image carrying medium and the object to be printed over the entire surface thereof.
