Abstract: Proposed herein is a rear projection screen for use with a single-light-source projector, causing no loss of imaging light and being highly uniform in screen brightness. The rear projection screen is a combination of two or more optical members for transmitting, diffusing, or condensing light, in the form of sheets or windable films. In this rear projection screen, the light diffusivity in the vertical direction of a light-diffusing element (a light-diffusing layer and/or an embossed surface) that is situated on the viewer side of the viewer-side outermost optical element of one or more optical elements that comprise lenses or prisms for diffusing light in the horizontal and/or vertical direction is higher at the upper and/or lower edge of the screen than at the center of the screen.

Abstract: A pair of feedback chambers is provided in a supply/discharge switching control valve, and the hydraulic pressure is introduced from a portion on the upstream side of the orifice provided in the communication passage through the second feedback passage, and is introduced from a portion on the downstream side of the orifice provided in the communication passage through the first feedback passage. Therefore, the responsiveness is enhanced, compared with the case where only the first feedback chamber is provided. Also, the overshoot and the undershoot of the fluid pressure, and the pressure fluctuation are effectively suppressed, compared with the case where only the second feedback chamber is provided.
