摘要： An optical integrated apparatus is used in an optical pickup apparatus which irradiates a light emitted by a light emitting device to an optical information record medium, on which record information is recorded, and receives a reflection light reflected from the optical information record medium. The optical integrated apparatus is provided with: a substrate; a light wave coupler for respectively generating a transmitted light and a guided light out of the reflection light; a light guide path for propagating the guided light; a first light receiving portion for receiving the transmitted light; and a second light receiving portion for receiving a radiant light which is generated out of the guided light and is directed toward the substrate due to a phase matching from the light guide path. The light wave coupler, the light guide path, the first light receiving portion and the second light receiving portion are laminated on the substrate. The first light receiving portion and the second light receiving portion are formed in a same layer on the substrate.

摘要： A liquid crystal display device comprises a converging reflector, a liquid crystal panel, a condenser lens and a projection lens, wherein a correlation between these optical parts and structure of sizes of the optical parts is considered. Accordingly, a convergence efficiency of the device as whole system can be improved. A converging reflector comprises a light source and a reflecting mirror reflecting a light from the light source, wherein a curved plane shape of the mirror is offset radially to the same length as a radius of a light emitting tube of the light source. Accordingly, a convergence efficiency of the converging reflector can be improved.

摘要： A liquid crystal projector is obliquely disposed in a lower front portion of a cabinet. A first mirror for reflecting light beams of R, G and B coming from the liquid crystal projector is disposed obliquely with respect to the top-bottom, right-left and front-rear directions of the cabinet. A second mirror is disposed so as to be inclined toward a screen. With this configuration, the optical axis of the light beams that extends from the liquid crystal projector to the screen is folded back three-dimensionally. In the liquid crystal projector, the optical axis of a condensing reflector may be slightly inclined from the central axis of a projection lens.

摘要： A four-wheel steering system for a motor vehicle steers motor vehicle rear wheels based on a steering angle ratio between front and rear wheels based on a vehicle speed, and a front wheel steering angle. The steering angle ratio is of a negative value or a relatively small positive value when the vehicle speed is in a medium speed range or a high speed range and the front wheel steering angle is in a relatively small range. The motor vehicle is controlled to turn well when the front wheel steering angle is in the relative small range while the motor vehicle is running in the medium and high speed ranges.
