Abstract: Image persistence of the spatial light modulator is suppressed. A projection device (1) includes: an illumination optical system (12) that emits light; an information processing unit (20) that generates a hologram pattern based on an input image; a spatial light modulator (14) that forms the hologram pattern generated by the information processing unit and transmits light emitted by the illumination optical system; and a projection optical system (16) that projects an output of the spatial light modulator onto a projection surface and projects an output image, and the information processing unit generates the new hologram pattern obtained by shifting the hologram pattern in a predetermined direction for every predetermined frame.

Abstract: An image display device includes: a first display panel and a second display panel in which transmittance or reflectance of light is controlled on the basis of an image signal; and a light irradiation unit that irradiates the first display panel and the second display panel with light, wherein the first display panel and the second display panel are sequentially driven by image signals corresponding to a plurality of color light beams, and in a period in which one of the first display panel and the second display panel is driven by an image signal corresponding to any one of the plurality of color light beams, an image signal for driving the other display panel is switched.

Abstract: The purpose of the invention is to provide a device convenient for carrying pallet loaded with article into and/or from container. The introducing device 3 is comprised of: the stage 5; the first lifting/sliding devices 13a, 13b, 13c and 13d, which support the pallet 11 to allow it to move horizontally while keeping it lifting up to the floor surface of the stage; and the second lifting/sliding devices 29a, 29b, 29c and 29d, which receive the pallet from the first lifting/sliding devices and support it to allow it to move horizontally while keeping it lifting up to the floor surface of the container 2. The introducing device 3 is possible to be used for discharging operations.

Abstract: A method of introducing/discharging a heavy article is provided that allows for introducing and/or discharging a coil-shape heavy article to and from a transporting receptacle. The method includes utilizing a pallet, a stage, and a carrying vehicle to introduce/discharge the coil-shape heavy article. A coil-shape heavy article is secured to the pallet using a securing member and is transported, while secured to the pallet, between the stage, which is secured to the transporting receptacle, and the transporting receptacle. The stage includes a table having a height that is adjustable relative the floor surface of the transporting receptacle. Movement of the pallet between the stage and the transporting receptacle is performed by levitating a support frame of the carrying vehicle on which the pallet has been positioned using a controllable discharge of gas exiting from exhaust nozzles of the carrying vehicle.
