摘要:
A liquid crystal panel unit is attached to a light incident surface of a prism composite. The liquid crystal panel unit includes a panel frame plate holding a liquid crystal panel, and a fixation frame plate glued and fixed to the light incident surface. The panel frame plate is fastened to the fixation frame plate by screws through an intermediate frame plate. By using wedges, the position of the panel frame plate with respect to the light incident surface is adjusted. This allows the liquid crystal panel to be reliably positioned and fixed so that the deviation amount in pixel matching is minimized and the focus adjustment can be accomplished correctly.

摘要:
A liquid crystal panel unit is provided on the light incident face of a prism combining body. The unit has a light valve frame plate for holding a liquid crystal panel and a fixing frame plate fixed onto the light incident face with an adhesive layer. The light valve frame plate is screwed onto the fixing frame plate with a medial frame therebetween. By using wedge members, by adjusting the position of the light valve frame plate on the light incident face, it is possible to precisely position and fix the liquid crystal panel which is held there so that it is possible to control the shifted amount of the pixel alignment and precisely adjust the focus. Thus, it is possible to easily improve the accuracy. Furthermore, the fixing frame plate and the light valve frame plate are composed of materials having linear expansion coefficients ranging from 1/4 to four times that of the prism combining body and from 1/5 to five times that of the fixing frame plate, respectively.

摘要:
A display device performs various types of adjustment by canceling luminance dispersion caused by a light source at the time of optical illumination from the light source and correctly sets a gamma correction characteristic even when optical power from the light source varies or is abnormal. In luminance measurement of a display device, an adjustment method includes measuring transmitted light using a sensor and a reference sensor, calculating correction values on the basis of fluctuation values of reference data derived from measured data by the sensor and the reference data by the reference sensor, correcting the measured data, and thereafter converting the data into gradation values.

The light emitted from a focal position-detecting light source 38 and reflected from a reflector 12 is projected onto a screen 341, and a projected image on the screen 341 is detected by a focal position-detecting camera 35. Based on this projected image, the focal position-detecting light source 38 is moved by a position adjusting system 37 so as to place the focal position-detecting light source 38 at a focal position of the reflector 12, and the position of the focal position-detecting light source 38 at this time is detected as the focal position of the reflector 12. When the focal position of the reflector 12 is detected, the projected image on the screen 341 detected by the focal position-detecting camera 35 is used, and, therefore, the conventional measurement by a three dimensional measuring instrument is made unnecessary, thereby improving the working efficiency.
摘要:
The present invention relates to dimedone functional self-bonding room temperature vulcanizable silicone rubber compositions. The self-bond additive is selected from silyl maleates, silyl fumarates, silyl succinates, silyl isocyanurates and mixtures thereof. Preferably the self-bonding additive is prereacted with the cross-linking agent before they are incorporated into the RTV composition. This prereaction of the self-bonding additive and the cross-linking agent imparts shelf-stability to the composition.
摘要:
A projector includes a first lens plate having a plurality of lenses, a second lens plate having a plurality of lenses, a light valve that modulates an output light beam from the second lens plate, and a light source apparatus. The light-source apparatus has a light-source lamp including an emission tube, a reflective mirror that reflects a divergent light beam from the light-source lamp to output a parallel light beam, the reflecting mirror having a reflective surface, a lamp housing that supports the reflective mirror, and an electrode lead. The electrode lead is led out of an end of the emission tube that is projected forward out of the reflective surface and is connected to an external connection terminal board which is positioned to a rear side of the reflective surface. The electrode lead is routed via the portion of the reflective mirror other than an effective area of the reflective mirror. A portion of the electrode lead positioned on the side of the reflective surface is arranged along a grove of a lens of the plurality of lenses of one of the first and second lens plate.
