摘要： A color separating/light guiding optics comprises two independent dichroic mirrors, reflection mirrors and correcting lenses. A horizontal plane region occupied by these optical components is entirely involved in a horizontal plane region occupied by a light modulating/color compositing/image projecting optics. A red beam is guided along a detoured optical path extending across a dead space below a projection lens. Although the optical path length of the red beam becomes longer than those of the blue beam and the green beam, the detoured optical path provides a sufficient space for installing the correcting lenses. The substantial optical path lengths of three primary color beams can be equalized with each other by the provision of these correcting lenses.

摘要： The medical handpiece of the present invention includes a cutting tool having a flexible shank and a cutting bur, a plastically deformable tubular casing for the cutting tool, a handpiece body detachably holding the cutting tool, bearing members disposed in the casing, an inner intervening member for receiving the shank, and an outer intervening member arranged around the inner intervening member. The inner and outer intervening members are composed of a plurality of segments, and each segment is arranged between or on distal or proximal side of the bearing members. Each segment of the outer intervening member is further composed of a plurality of sub-segments. Annular members having the outer diameter that is larger than that of the outer intervening member are arranged between the sub-segments of the outer intervening member. The present handpiece provides improved operationality since shaking is hardly generated even when the casing is flexed.

摘要： An image display apparatus includes a diaphragm (9b) arranged at a pupil position. The shape of an aperture of the diaphragm (9b) is similar to the shape of a light source image formed by an illuminating optical system at the pupil position. An area varying mechanism (90) varies the area of the aperture of the diaphragm (9b) in response to a focal length varying operation of a projection lens (9). This prevents an excessive opening from being formed around a light source image cast by the illuminating optical system, thereby preventing the deterioration of displayed images due to unwanted light that may pass through the excessive opening.

摘要： A color-separating and -recombining optical system provided between a light source and a projection lens in a projection display, has at least one prism assembly made up of at least two prisms bonded to each other with a bonding layer formed between the prisms. A white light emitted from the light source is divided into red-, green-, and blue-color light components related to primary colors. The light components are modulated by spatial light modulators in accordance with a video signal. The modulated light components are combined and projected onto a screen via the projection lens. The thickness of the bonding layer is varied as thin and thick for optical paths long and short, respectively, from the spatial light modulators to the bonding layer which each modulated light component emitted from the corresponding spatial light modulator reaches.
