Abstract: According to one aspect of a preferred embodiment of the present invention, a carpet for vehicles comprises a surface skin layer 2 and a sound absorption layer 3 made of a nonwoven fabric integrally bonded to the surface skin layer 2 via an adhesive resin layer 4. The adhesive resin layer 4 is constituted by an air permeable resin layer formed by melting thermoplastic resin powder having a particle diameter of not smaller than 320 ?m but not larger than 1,000 ?m. An adhered amount of the thermoplastic resin powder is 180 to 500 g/m2. Air permeability of the entire carpet in a thickness direction thereof is 10 to 26 cm3/cm2·sec. With this structure, excellent sound absorption performance can be exerted against noise entering into an inside space of a vehicle from the above side, such as, the roof, doors, or windows, as well as noise entering from the lower side.

Abstract: A sound absorbing carpet according to the present invention is characterized in that a sound absorbing nonwoven fabric layer is integrally bonded to a lower surface side of the surface skin material layer via an adhesive film layer made of thermoplastic resin, and a part of fibers constituting the sound absorbing nonwoven fabric layer are constituted by thick fibers of 11 to 220 desitex, and the adhesive film layer is provided with a number of permeable pores formed by being contacted by the thick fibers.

Abstract: The present invention relates to a method and apparatus for image compression in block units, and particularly to the image editor, color equalizer and error diffuser functions thereof. According to this image compression method, processing is done in blocks of 4×4 pixels. In each block, two representative colors and two interpolated colors that are gained by linear interpolation between the two representative colors, i.e., four colors in total, are used. One of these four colors is allotted to each pixel. The image editor function directly edits the reference relationship between the representative color and the color of the pixels. The color equalizer function performs encoding by taking differences in coloring between a TV and a PC monitor in consideration, thereby reproducing images similar to colors seen by the PC user on the TV of a game machine.

Abstract: A sound absorbing carpet according to the present invention is characterized in that a sound absorbing nonwoven fabric layer 6 is integrally laminated on a lower surface side of a surface skin material layer 10, and flat cross-sectional fibers are used as at least a part of fibers constituting the sound absorbing nonwoven fabric layer 6. Furthermore, another sound absorbing carpet according to the present invention is characterized in that a sound absorbing nonwoven fabric layer is integrally bonded to a lower surface side of the surface skin material layer via an adhesive film layer made of thermoplastic resin, and a part of fibers constituting the sound absorbing nonwoven fabric layer are constituted by thick fibers of 11 to 220 desitex, and the adhesive film layer is provided with a number of permeable pores formed by being contacted by the thick fibers.

Abstract: An upper surface layer 2 and a nonwoven fabric sound absorption layer 3 are integrally secured via an air permeable adhesive resin layer 4 formed by melting thermoplastic resin powder, and the air permeability of the thickness direction of the entire carpet 1 falls within the range of 1 to 50 cm3/cm2·second. This effectively absorbs noise from the upper side entering via a roof, doors and windows as well as noise from the lower side. The carpet can be manufactured by scattering thermoplastic resin powder on an upper surface member, heating the thermoplastic resin powder into melted thermoplastic resin, placing a nonwoven fabric on the upper surface member via the melted thermoplastic resin, and pressing the nonwoven fabric and the upper surface member in a laminated state. It is preferable that powder of particle size of 90 to 10,000 ?m is scattered in the amount of 5 to 500 g/m2.

Abstract: A functional carpet suitable for use in an automotive vehicle. The functional carpet comprises a nonwoven fabric having piles formed throughout a whole surface of the nonwoven fabric. Each pile projects from the surface of the nonwoven fabric and is formed of at least a part of fibers constituting the nonwoven fabric. Each pile has a length ranging from 1 to 10 mm. The nonwoven fabric has a density ranging from 250 to 800 g/m.sup.2. Additionally, a fluoroplastics is adhered to a surface portion of the nonwoven fabric and extends substantially uniformly throughout the surface of the nonwoven fabric. The fluoroplastics includes linear tetrafluoroethylene telomer as a main body. The tetrafluoroethylene telomer has a number of carbon atoms ranging from 6 to 14. The amount of the fluoroplastics adhered to the surface portion of the nonwoven fabric ranges from 1.5 to 60 g/m.sup.2 in solid state.
