  • Patent number: 7771375
    Abstract: A cushion comprises a resin body with a spring structure having permeability comprising a three-dimensional structure including voids at a predetermined bulk density, the three-dimensional structure being obtained by contacting, entwining, and gathering adjacent ones of random loops or curls of continuous filaments made from a thermoplastic resin in such a manner as to allow the resulting structure to have a layered structure in which layers composed of filaments having a high bulk density as superficial layers are formed on a front and a rear of the resin body in a lengthwise direction, and a layer composed of the filaments having a low bulk density as a core layer is interposed between the superficial layers; and a speaker incorporated in the resin body or disposed on one of the superficial layers of the resin body.

  • Patent number: 7377762
    Abstract: The present invention relates to a resin-molded article with a spring structure, and to a method and apparatus for preparing a superficial layer of such a resin-molded article with a spring structure which has surfaces free from undulations, comprises fused filaments whose fusion is resistant to separation, maintains its cushioning activity and strength even after long use. A water flows from a cooling water outlet 53b into a space between a water-permeating sheet 55 and an inclined plate 51a. Some part of the flowing water C penetrates the water-permeating sheet 55 to appear on its top surface to form there an overlying current M on which receives lengthwise arranged peripheral continuous filaments, and agitates them to cause adjacent filaments to contact each other, to be entwined and gathered, thereby enabling the formation of a superficial layer of the three-dimensional structure 3.

  • Patent number: 7087161
    Abstract: A resin cultivating base serves as seedling beds for vegetation which are planted and are partially immersed in a river, lake, marsh, pond or waterway. The resin cultivating base is a three-dimensional structure constituted by long and short filaments of thermoplastic resin. The long and short filaments are curled or looped at random, and contacted, entwined and gathered, thereby forming a low density portion and a high density portion. Vegetables planted on the low density portion of the resin cultivating base suck nutritious salt such as phosphor and nitride. Microorganisms living in the resin cultivating base decompose organisms in the water, thereby purifying the water.

  • Patent number: 6347790
    Abstract: An object of the invention is to provide a shock absorber which can reduce damage to the member to collide therewith. The invention provides a shock absorber comprising a cushion structure of three-dimensional spring construction, which has a large void provided by a random curl or loop formed by hot extruding a thermoplastic resin to form a continuous strip and curling or looping the strip in a molten state to bring adjoining strip sections into interlocking contact with each other. In the invention, the cushion structure may be obtained by stacking a plurality of cushion structure members, each having high cushion performance and buckling resistance and a certain thickness, one upon another parallel in a thickness direction or rolling up one side of a cushion member with a given thickness. Then, the cushion structure is embedded in a foamed and hardened filler containing a hydratable, hydraulic binder while a part of the cushion structure is exposed on an shock-receiving surface.

  • Patent number: 6280842
    Abstract: Wood meal comprises wood meal granules formed by crushing raw material wood into treated wood meal and pulverizing the treated wood meal under the frictional forces of a plurality of balls such that the bulking density of the treated wood meal is increased; and a plurality of particles fixed on the surfaces of the wood meal granules by an external pressing force. The particles are smaller than the wood meal granules such that the wood meal granules are coated with the particles. The particles are also harder than the wood meal granules such that the particles are pressed into the wood meal granules surfaces from the application of the external pressing force.
