Abstract: A white light beam from a light source portion (201) is separated into respective light beams of red, green and blue by a color separation optical system (204). The respective light beams are reflected by a rotating polygon mirror (207), travel via a second optical system (210) and form belt-like illuminated regions on an image display panel (212). By a rotation of the rotating polygon mirror (207), the illuminated regions of the respective light beams move continuously, and each pixel of the image display panel (212) is driven by a signal corresponding to a color of light entering this pixel. An image on the image display panel (212) is magnified and projected onto a screen by a projection optical system (216).

Abstract: A projection display system includes: two light sources (102, 105); a condenser (103, 106) for condensing the light from the light sources; a time-division color separating optical system (108) for temporally switching the incident light into a first, second, or third color of light to be emitted; a light valve (118) capable of modulating the incident light individually for each pixel; a lighting optical system (111, 112, 114) for directing the light from the time-division color separating optical system onto the light valve, and a projection optical system (123) for magnifying and projecting a pixel on the light valve. The light from the two light sources (102, 105) is condensed on the time-division color separating optical system or its vicinity by the condenser (103, 106), and then superimposed. This can provide a projection display system that performs time-division driving and can achieve high-brightness projection images without increasing the size and cost of a system.

Abstract: A water purifier 40 includes a flow meter 42 for measuring the cumulative flow of water through a water purification cartridge 6. The flow meter has an indicator portion 44 that rotates in response to increasing cumulative flow and a graduated portion 46 rotating about the same axis as that of the indicator portion. The graduated portion includes an insertion groove 29 for manually rotating the graduated portion in order to reset the flow meter. Because the flow meter has few part, the body of the water purifier can be made compact and its cost reduced.

When the user changes an access destination between two Web pages, the user operates an URL link provided in a transition source Web page to change the access destination. As the URL link is operated, its HTTP request is transferred to a transition source Web system that provides the transition source Web page. The transition source Web system decides certification information according to a contract agreed with a Web system that provides a transition destination Web page that is a transition destination indicated by the URL link, and returns to the user information including identification information that specifies the transition destination Web page and the certification information.

Abstract: Three colors of light beams from a light source travel via a first optical system to strike a reflecting surface of a rotating polygon mirror, or mirrors, at different angles without overlapping. The rotating polygon mirror or mirrors reflect the light beams for scanning. The reflected light beams enter a second optical system at different angles to illuminate an image display panel at different portions. On the image display panel, belt-like regions illuminated by the light beams of individual colors are formed in parallel with each other, and these illuminated regions are moved continuously by scanning. A formed color image is magnified and projected by a projection optical system. With such a projection type image display apparatus, a display having high resolution and light efficiency that is also small, thin and inexpensive is achieved.

Abstract: Red, green and blue light beams from, a light source portion travel via a first optical system and enter a reflecting surface of a rotating polygon mirror at different angles so as not to overlap each other. The rotating polygon mirror makes these light beams perform scanning when reflecting these light beams. The light beams for the scanning enter a second optical system at different angles and are led to different positions on an image display panel. The second optical system forms an image that is rotated by 90° from that on the rotating polygon mirror on the image display panel. On the image display panel, belt-like regions illuminated by the light beams of individual colors are formed in parallel with each other, and these illuminated regions are moved continuously by the scanning. Each pixel of the image display panel is driven by a signal corresponding to a color of light entering this pixel. A formed color image is magnified and projected by a projection optical system.
