Abstract:
PURPOSE: To provide a projector in which the image positioning by the effective reflected light projected from a mirror light bulb can be precisely performed with a simple mechanism by switching a fixing means to two directions according to fixation and fixation release, and performing the fixation or fixation releasing of a regulating means to a support member. CONSTITUTION: A display panel is mounted on the first, second or third plate 70, 80, 90 of a regulating means 50, and held on a moving plate 37 through a support member 60. Each of the first, second and third plates 70, 80, 90 of the regulating means 50 is minutely moved in horizontal, vertical and rotating directions, respectively, whereby the effective reflected light of each display panel is positioned, and a fixing means 102 is switched to two directions according to fixation or fixation release, whereby the fixation or fixation release is performed to set the position of each display panel. Thus, the regulating means 50 is fixed to or fixation-released from the support member 60, whereby the working property in the positioning of the effective reflected light of the display panel can be remarkably improved.
Abstract:
PURPOSE: To improve use efficiency of light by forming illumination light which circularly color-changes with two different colors and emitting it in different directions. CONSTITUTION: The emitted light of a light source 2 is made incident on a filter part which is vertically provided at the peripheral part of a two color transmission color wheel 21 through a condenses lens 3 at the angle of 45 degrees. At this point, only light flux L2 having the same color as the peripheral filter reaches a reflection mirror M1, other color light flux reaches a filter disk part which is concentric with the wheel 21 and light flux 3L having the same color reaches a reflection mirror M5. Since the colors of the peripheral filter and the filter disk are made different, the light fluxes of two colors can simultaneously be guided to the other directions and light can be used twice. Thus, the heights of respective optical paths are varied by making the light fluxes incident on mirror reflection-type light bulbs 7a and 7b from obliquely upper and lower directions through the reflection mirrors M2 and M5. Then, the intensity distribution of light in a projected picture can be made uniform by projecting the picture on a screen center from a position being a rotary object.
Abstract:
PURPOSE: To simplify and miniaturize constitution and to make the luminance of a display video to be high by processing the valid reflected light of a mirror deflection-type light modulator with a relay lens, a variable light shielding means and the like. CONSTITUTION: High luminance white light passing through a condenser lens 4 and a reflection mirror 5 in a projector device 40 is separated into respective color light beams in separation dichroic mirrors 6R, 6G and 6B. Respective color valid reflected light beams corresponding to R, G and B signals by the mirror light bulbs 2R, 2G, 2B of the mirror deflection-type light modulator are synthesized in the relay lens and the dichroic mirrors 9R, 10R, 9G, 10G, 9B and 10B. Synthesized light is made incident on the projection lens 11 through the variable aperture of the variable plate 43 of the variable light shielding means having masking plates 45a and 45b which can freely and relatively move on a base plate 44 having an opening. Thus, a picture at the peripheral part of a valid modulation area is removed, constitution is simplified and miniaturized and the luminance of the display video can be improved with constitution using the mirror deflection-type light modulator and the variable light shielding means.

Abstract:
PROBLEM TO BE SOLVED: To provide a three-dimensional shaping device which can make a shaped article giving an impression close to an actual article, its control device, a control method and a shaped article created by the three-dimensional shaping device. SOLUTION: In a step 102, an image processing computer executes at least multivalued processing beyond a binarization level with regard to the brightness of stored DICOM data. In a step 103, an image colored with a plurality of different colors corresponding to brightness information by a plurality of stages is formed based on the brightness information by a plurality of stages corresponding to the multivalued processing. The three-dimensional shaping device draws an image in powder by discharging not smaller than two different colors of inks to a single layer-worth powder layer (step 107) based on the colored image. This procedure is repeated in a plurality of layers (step 108). COPYRIGHT: (C)2010,JPO&INPIT
