Abstract: A dichroic or trichromatic transparent display apparatus through which a background view is seen comprises a transparent substrate, a hologram formed on a rear face of the transparent substrate, a dispersion liquid crystal device disposed in front of a front face of the transparent substrate, a light source disposed for facing a side face of the transparent substrate and a transparent layer at least partially provided between the transparent substrate and the hologram. The refractive index of the transparent layer is smaller than that of the transparent substrate. A first light emitted from the light source and having a first wavelength is totally reflected by the boundary face between the transparent substrate and the transparent layer so that the first light moves to and is diffracted by a first region of the hologram where the transparent layer is not provided. A second light having a second wavelength is diffracted by a second region of the hologram where the transparent layer is provided.

Abstract: To achieve a backlighting device having excellent light utilization, there is provided an edge lighting-type backlight having a light guiding member, a high-refractive-index layer formed thereon and having a higher refractive index than the light guiding member, and a scattering layer formed on the high-refractive-index layer.

Abstract: The liquid crystal display device according to this invention realizes three-dimensional picture images without using lenticular lenses etc. In addition, this liquid crystal display device has a transparent picture screen so that remote display picture images or three-dimensional picture images of high luminance are seen multiplexed with the background. The display device is constructed by arranging picture elements in which volume-phase type holograms are formed by a periodical construction of liquid crystals and polymers. Diffraction light from first picture element groups which are distributed uniformly reaches a left eye of an observer while diffraction light from second picture element groups which are distributed uniformly reaches a right eye of an observer. The condition of the picture elements are switched to diffract irradiated light or to transmit the light, thus a desired picture image comprising a dot matrix can be displayed.

Abstract: A vehicle behavior during driving is correctly grasped by computing and map-retrieving from output signal (.omega.y) of an angular velocity sensor (2) for detecting the angular velocity of the vehicle (11). A vehicle control apparatus of the present invention can correctly compensate the output signal (.omega.y) having error owing to the secular change or temperature change, etc. by using a zero-point calculation means (6, 16, 26, 36, 46, 56) for calculating zero-point signal (.omega.y0) and an angular velocity correction means (7, 17, 27, 37, 47, 57) for correcting the output signal (.omega.y) of the angular velocity sensor (2).

Abstract: A suspension control apparatus for a vehicle having at least one shock absorber with a controllable damping force. The suspension control apparatus includes a roll angular velocity sensor for detecting angular velocity about a roll axis of the vehicle, and control means for determining a bumpy-road driving state of the vehicle when an accumulation time exceeds a predetermined accumulation time. The control means adjusts the damping force of the shock absorber during the bumpy road driving state. The accumulation time represents the amount of time the angular velocity exceeds a predetermined angular velocity range during a first predetermined time period.
