Abstract: An interior part of a vehicle comprises an outer wall constituted by a resin and/or a material containing the resin, and a thermal conductive member joined to the outer wall. The thermal conductive member is partially joined to a vehicle body panel and/or a metal part engaged with the vehicle body panel, so that temperature increase in a vehicle cabin is controlled effectively.

Abstract: An angle selective reflection sheet which is comprised of an angle selective transparent sheet having a characteristic of selectively reflecting light according to an incident angle of incident light to the angle selective transparent sheet, and a reflection layer laminated on a surface of the angle selective transparent sheet. The angle selective reflection sheet is preferably applied to surface members of an instrument panel, a door trim, a rear parcel shelf, a pillar garnish and a steering wheel.

Abstract: A vehicle body panel structure comprises an outer panel, an inner panel facing the outer panel, and a trim of a cabin interior. In the vehicle body panel structure, at least one surface of a back surface of the outer panel, both surfaces of the inner panel, and a surface of the trim facing the outer panel has both functions of heat insulation and heat dissipation by partially providing a heat insulation section to insulate heat for the at least one surface.

Abstract: A reflecting surface material for a vehicle interior, including multiple units of reflecting material each having a surface defined by a concave cross-sectional profile with at least one light reflecting face formed in one sector of the profile and at least one light absorbing face formed in another sector of the profile. A plurality of units of reflecting material are positioned such that the light reflecting faces are disposed in one direction toward the exterior of the vehicle and the light absorbing faces are disposed in another direction toward the driver of the vehicle.

Abstract: A vehicle body structure has a heat radiation insulating arrangement that improves the thermal environment inside a vehicle cabin when the vehicle is positioned at a sunny location during hot weather by increasing the insulation effects of the automobile body along with blocking radiant heat. The heat radiation insulating arrangement of vehicle body structure forms a first space by arranging a light shielding shade on the inside of a windowpane, a second space formed between the exterior roof panel and ceiling material, and an air passageway that links the first space and the second space to allow the air to flow from the first space to the second space. A reflective material is provided on the surface of the second space of the ceiling material.

Abstract: A skin structure is constituted by laminating a space holding layer 1 and a low lightness layer 2 on a base material 3, laminating the space holding layer 1 on a base material 4 of low lightness, or laminating a space holding layer 5 of low lightness on the base material 3. Accordingly, an increase in surface temperature of an interior material caused by direct solar radiation or solar radiation through glass and reflection in a window can be prevented.

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.

Abstract: A method for evaluating the gloss and brightness character of a coated paint film. The method is comprised of projecting a brightness and darkness pattern onto the surface of the coated paint film. The projected pattern is picked up by a CCD camera and converted to a two-dimensional brightness and darkness pattern image. The disturbance of the pattern image is separated into a plurality of spatial frequency ranges. Each of the spatial frequency ranges is independently quantified to obtain an evaluation value which is in close correlation to a corresponding organoleptic evaluation value based on human's visual observation.

Abstract: A method for evaluating a gloss and brightness character of a coated paint film. The idea of the gloss and brightness cahracter is classified into three feelings, i.e., a smooth feeling, a thickness feeling and a gloss feeling. Three frequency regions for the respective three feelings are selected to be in well correlation to organoleptic values which are for the respective three feelings. In the evaluating method, the degree of a surface roughness of the coated paint film is converted into frequency components. Then the frequency regions are abstracted from the frequency components. The frequency regions are numerically estimated. Finally, the gloss and brightness character of the coated paint film is evaluated in accordance with the numerically estimated frequency regions.
