摘要： A color combining optical system includes a first polarization splitting surface for light in a first wavelength range, and a second polarization splitting surface for light in a second and third wavelength range. The first polarization splitting surface guides illumination light in the first wavelength range to a first liquid crystal display (LCD) element and guides image light reflected from the first LCD element to a direction different from the illumination light. The second polarization splitting surface separates illumination light in the second and third wavelength range from each other, guides them to a second and third LCD element, respectively, and combines image light reflected from the second LCD element with image light reflected from the LCD element to guide combined light to the first polarization splitting surface which combines the image light reflected from the first LCD element with the combined light.

摘要： A steering device is provided for controlling steering torque applied to a steering wheel of a vehicle. A braking device is provided for controlling longitudinal force applied to each wheel, and a control device is provided for performing at least one of an anti-skid control and a traction control. It is observed whether the control device is performing the control on a split road surface. The steering torque is controlled on the basis of a difference of longitudinal force applied to the right and left wheels, and a turning state amount deviation between a turning state amount and a desired amount thereof. The desired amount of turning state is calculated, on the basis of the turning state of the vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.

摘要： Conventionally, concentrated illumination of a central portion of an image (about 40-60% of the whole image) in which information such as letters and a picture tends to concentrate (centrally concentrated illumination) and uniform illumination of the whole image (uniform illumination) can be carried out by using two separate apparatuses, but no single conventional image display apparatus can carry out both of the two types of illumination. Accordingly, an object of the present invention is to provide a liquid crystal display apparatus which can carry out centrally concentrated illumination, uniform illumination, and various other illumination states (illumination distributions). According to the present invention, an image display apparatus (such as a liquid crystal projector) is structured such that a fly-eye lens or a part thereof in an illumination optical system for illuminating an image forming element is moved to vary the illumination distribution on the image forming element.
