An apparatus synthesizes the image of a viewer and a second image into a synthesized image and displays the synthesized image. The apparatus is capable of aligning the line of sight of the viewer with the line of sight of the displayed image of the viewer and correctly reproducing colors on the synthesized image. The apparatus has a transparent hologram screen (15) on which a diffuser is recorded, a camera (25) for imaging a viewer (81) through the hologram screen, a synthesizer (28) for synthesizing the image of the viewer and a second image into a synthesized image, and a projector (11) for projecting signal light (31) containing the synthesized image onto the hologram screen. In place of the synthesizer, a display unit may be arranged behind the viewer. The hologram screen (15) may be combined with a mirror or a half-mirror.

Apparatus for synthesizing and displaying images

A swash-plate type compressor comprises a plurality of cylinder chambers parallel to each other, a shaft, a swash plate connected to the shaft for rotation therewith and for wobbling motion due to the rotation, and a plurality of pistons subject to wobbling motion of the swash plate for reciprocation within the respective cylinder chambers. The shaft and the swash plate are connected to each other through a slot formed in one of them and a pin provided on the other, so the swash plate can wobble. A position of a center of rotation of the swash plate is supported by a spool device movable in coaxial relation to the shaft. Displacement of the spool device causes the position of the center of rotation of the swash plate and an inclination thereof to be varied to vary a reciprocative stroke of each piston, thereby controlling discharge capacity of the compressor. The engaging slot has a section thereof between positions corresponding respectively to a maximum discharge capacity and an intermediate discharge capacity of the compressor, which section is formed into a nonlinear configuration in such a manner that an angle between a normal line of the slot and an axis of the shaft decreases at a position corresponding to a large discharge capacity of the compressor, thereby restraining an increase in inclined moment acting upon the swash plate due to a dead volume occurring in the working chamber on one side of the piston at a large capacity of the compressor.

Variable-capacity swash-plate type compressor

A swash plate type compressor has a rotary shaft, an inclined swash plate for rotation with the shaft, and a plurality of pistons connected to the swash plate. Each piston defines at both ends thereof a pair of working chambers. The piston reciprocates while being subjected to a swing motion concomitant with the rotation of the swash plate, to suck a fluid into the working chambers for compression. The swash plate is mounted on the shaft through a support unit which serves to selectively vary the inclination of the swash plate and shift the center of rotation of the swash plate along the shaft. The fluid is introduced from a suction passage through and around the swash plate to suction chambers formed adjacent the working chambers. A bypass passage is formed to directly communicate the suction passage with the suction chamber on one side of the shaft while bypassing the swash plate. When the inclination of the swash plate is decreased and the rotational center position thereof is shifted so that substantially no compression of fluid is completed in the working chambers on the one side of the shaft to decrease the displacement of the compressor, the fluid flows in the one side suction chamber through the bypass passage responsively to the flow of fluid toward another side working chambers to lubricate and cool sliding parts for the shaft.
