  • Publication number: 20040222671
    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.

  • Patent number: 6805192
    Abstract: A heat radiating structure of an interior member is provided with a heat radiating portion adapted to be applied to a vehicle and disposed on a rear surface of an interior member whose surface is adapted to be applied with external energy, a heat receiving and radiating portion connected to a vehicle body of the vehicle, and a reflecting member allowing heat radiation, radiating from the heat radiating portion to an inside of the interior member, to be reflected and propagated to the heat receiving and radiating portion. The reflecting member cooperates with the heat radiating portion and the heat receiving and radiating portion to define a closed space.

  • Publication number: 20040124668
    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.

  • Publication number: 20030174279
    Abstract: When a photographing switch (55) is operated, a mirror (26) is moved out of the optical path, a strobe (14) is made to emit a flash of light, and the eye to be examined is photographed by a photographing unit (33). The image of the eye is recorded in image primary recording means (52). In such an arrangement, the image of an eye to be examined can be recorded in image primary recording means provided in the unit of the photographing device. Therefore, the image can be taken independently of the recording preparation state of an external recording device, the timing of flash of the strobe can be set not through an external recording device, and the image of an eye can be reliably and smoothly recorded. Further, since the image recorded in image primary recording means can be recorded in image secondary recording means (60), the same effect of recording the image in an external recording device can be produced if the image secondary recording means is provided to an external recording device.

  • Patent number: 6312542
    Abstract: The invention relates to a fibrous acoustical material for reducing noise transmission. This fibrous acoustical material comprises first, second and third fibers. The first fiber has a first fineness of 1.5-20 deniers and a first softening point. The second fiber has a second fineness of 1.5-15 deniers. At least a surface of the second fiber has a second softening point which is at least 30° C. lower than the first softening point. The third fiber has a third fineness of 1.5-15 deniers. At least a surface of the third fiber has a third softening point which is lower than the second softening point and at least 80° C. lower than the first softening point. The first, second and third fibers are respectively in amounts of 10-90 wt %, 5-85 wt % and 5-85 wt %, based on a total weight of the first, second and third fibers. The first, second and third fibers are each within a range of from 20 to 100 mm in average fiber length. The fibrous acoustical material has an average apparent density of from 0.01 to 0.

  • Patent number: 6168515
    Abstract: A vehicle air conditioning control system includes an actuator for controlling the position of an outside air intake door and an ambient exhaust gas sensor. A controller of the control system monitors a time rate of change of the degree of uncleanness periodically measured on the basis of the output of the sensor, and commands the actuator to bring the intake door to the fully closed position for the inside air recirculation mode if a first requirement about a previous exhaust gas concentration change and a second requirement about a current exhaust gas concentration change are both met.

  • Patent number: 6132838
    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.
