Abstract: A PC 40 outputs a picture signal for a white color to a TV 100, and generates chromaticity information by measuring luminance values of respective RGB color components from a picture displayed on the TV 100, thereby determining whether the chromaticity information undergoes a change by varying an output of any of the RGB color components by a predetermined amount. Subsequently, when the chromaticity information has not undergone a change, the contrast of the TV 100 is lowered by a predetermined amount, and re-acquisition re-determination of chromaticity information is executed. On the other hand, when the chromaticity information has undergone a change, determination is made on whether the chromaticity information substantially matches chromaticity information representing white, and in the affirmative case, a white balance adjustment value is stored in an EEPROM 112 while in the negative case, the re-acquisition/re-determination of chromaticity information is repeated.

Abstract: The piston 4 comprises a fixing ring 8 mounted on a piston rod 6, and a piston body 10 fixed to the fixing ring 8. The fixing ring 8 is comprised of two semi-circular plated members 8A, 8B having plural threaded holes 8a for bolt-fastening of the piston body 10. When they are abutted against each other and formed into a circular-annular shape, a hole portion 8c which is to be tightly fitted in a fixing groove 6a of the piston rod 6 is formed. The piston body 10 has a hole portion 10a which is to be fitted over the piston rod 6, and plural bolt holes 10c corresponding to the threaded holes 8a. Moreover, the piston body 10 has a concave portion 10d on a side of one surface thereof, in which the fixing ring 8 is fitted in an embedded state.

Abstract: A display module supporting structure including a display module having a circuit board carried on a rear surface thereof, a intermediate support members being interposed between a rear surface of the display module and an external support member for supporting the display module from the outside of the display module, the intermediate support members including first fixing surfaces fixed onto the rear surface of the display module, second fixing surfaces substantially parallel to the first fixing surfaces and formed in predetermined locations thereof with fixing portions for fixing the external support member, and connection surfaces interconnecting the first fixing surfaces and the second fixing surfaces and substantially perpendicular to the first fixing surfaces and the second fixing surfaces, and the intermediate support members being fixed to left and right locations on the rear surface outside the circuit board.

Abstract: Since size and mounting method of display panels of a large-sized panel type television differ by manufacturers, different parts are needed for display panels of different manufacturers. The display panel fixing plate is separated into a panel top fixing plate, a panel bottom fixing plate, and a bridge plate. The panel top fixing plate is fixed to the upper side of a flat display panel and the panel bottom fixing plate to the lower side of the flat display panel, and both plates are held with two bridge members. In addition, by making a screw hole vertically oblong that is used for screwing the bridge member to the panel top fixing plate, it is possible use the same panel top fixing plate, the panel bottom fixing plate, and the bridge plate for different inch display panels.

Abstract: The present invention discloses a projector device comprising: a housing body having a first insertion slot formed in a wall portion thereof; a control substrate; a metal-made shield frame arranged and fixed within the housing body and fixed to the housing body for allowing the control substrate; a reinforcing bracket for reinforcing the first insertion slot; the reinforcing bracket including a reinforcing surface and an extension surface extending to be perpendicular to the reinforcing surface; the reinforcing surface having a second insertion slot; a positioning section provided on an inner surface of the wall portion of the housing body for causing the reinforcing bracket to be positioned with respect to the housing body with the second insertion slot of the reinforcing bracket being aligned with the first insertion slot; and a screw for causing the extension surface positioned by the positioning section to be coupled to the shield frame.
