Abstract: An acoustic apparatus includes: a three-dimensional network structural body that is an aggregate of filaments that are made of a resilient resin, each randomly looped or curled, fused to each other, and intertwined with each other; an at least one speaker that generates acoustic waves; and a board-like resonance board. The three-dimensional network structural body has a front surface that is held in direct or indirect contact with a human body, and an inner surface that faces the front surface. The at least one speaker includes a vibrating portion that faces the inner surface of the three-dimensional network structural body, and a frame portion that holds the vibrating portion while allowing the vibrating portion to vibrate. The frame portion is mounted to one side surface of the board-like resonance board through intermediation of a resilient mounting material.

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.

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.

Abstract: There is provided a method for producing a cushion material composed of a resin molded article with a spring structure which is so moldable as to allow the mold take any shape and size, is cheap, and resistant to collapsing, does not cause fatigue even after prolonged use, and has high shock absorbing capability and load capacity, and thus suitably used as a material of any supports on which one can sit, rest or mount such as seats of automotive vehicles, motor cycles, bicycles, electric trains, and aircraft, saddles for horse riding, chairs, sofas and beds, and a method for producing a cushion material requiring only a low cost for its disposal.

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.

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.
