Abstract: Pressurized fluid enters by way of the flow control valve 90 which regulates flow and thus simulated raindrop size, through the fluid supply tube 80 and enters the fixed fluid distributor body 20, past a rotational seal 154 and into the rotating shaft 10, cushioned by the accumulator chamber 50. As the rotating shaft is made to rotate by means of the drive motor 60 and transmission means 70, the radial outlet port(s) 14 sequentially line up momentarily with each side port 26, allowing fluid flow through each outlet tube 30-35 in turn overflowing each respective conical vessel 40-45 to create a fluid drop at the lower point 48 which falls as simulated rain 160 in a desired three dimensional array. Each raindrop is thus timed perfectly according to the speed of rotation of the rotating shaft 10. The transducer 100 produces an electrical pulse for each rotation, also perfectly timed to the raindrops, which is input to the triggered oscillator 110 to ultimately control the strobe light 140.

Abstract: A three-dimensional image reproducer receives a video signal including three-dimensional information including X and Y information constituting a plane and Z information constituting a depth. This apparatus causes particles to fall with respect to one line. The line from which the particles fall is changed in the Z direction based on the Z information.

The focal point of the light beam is controlled to move in the Z direction in synchronism with the change of the line from which the particles fall. The image formed by the particles is viewed as a three-dimensional image if viewed from the Z direction.

Abstract: In accordance with one embodiment of the present invention, liquid material enters circumferencially into a generally cylindrical outer walled chamber. A baffle may be provided to facilitate circumferencial flow. The tangential, circumferencial flow tends to reduce turbulence. In the outer chamber a top wall is provided and a cushion of air is located between the top wall and the top of the liquid medium to effect cushioning. After circumferencial flow, the liquid flows radially inwardly into an inner fluid chamber through a plurality of openings in an inner cylindrical wall. Within the inner chamber and spaced between the bottom wall and the top wall is a diffuser section. The diffuser section provides a large plurality of parallel fluid flow paths to dampen remaining major currents by lowering the fluid velocity and thus the Reynolds number. The upper surface is arcuate. Thus fluid flows radially upwardly and inwardly to a knife-edged type orifice which results in laminar fluid flow exiting therefrom.
