摘要： A motion picture apparatus and method for intermittently advancing motion picture film by forced air. The film is initially placed into successive loops formed by closure of a rotary air valve. The loops and thus the film are advanced through the projector or camera pathway by a forced air blower which propels the successive loops through a projection pathway by opening of the rotary air valve. The film loop is metered by timing the opening and closing of the rotary air valve with the opening and closing of the shutter of the motion picture apparatus.

摘要： The present invention provide a fan to generate airflow to pass around a lamp reflector with an organized figure of column and cone. A wake region is formed on a leeward surface of the lamp reflector, and a light cut is installed on the wake region. The light cut has a fixing end and is fixed on a side end surface of a lamp holder of the lamp by means of fastening bolts, the other end keeps a selected distance away from the lamp reflector and has a suitable distance along contours of the lamp reflector toward a rear end of the lamp reflector so as to that to prevent the light with high illumination going through the lamp reflector to the exhausting outlet for avoiding light leakage; hence, the exhausting outlet shall not be added inclined louvers and the windage is lowered down comparatively. Therefore, the heat-dissipating efficiency is raised to effectively reduce the heat loading of the projector, promote products life and decrease noise.

摘要： A projector includes a duct having a connecting end for connection to an air inlet provided in a housing, and an air intake end for drawing in outside air for cooling the interior of the projector. The duct is made of a soft or flexible material and is capable of altering its shape. Thus, the duct can change the position of the air intake end in space, for example, to different positions. Further, the duct is pivotable on a pivot axis, and thus can change the opening direction of the air intake end circumferentially about the pivot axis. Therefore, selection of the position and/or opening direction of the air intake end so as to draw in the outside air suitable for cooling the interior depending on the usage forms of the projector achieves efficient cooling of the interior of the projector.

摘要： A projection type display device, in which efficient cooling is performed is operated so that the display device is operated in a remarkably silent manner, is provided. The projection type display device includes: a light source unit 66; an optical unit 50 for modulating illumination light output from a light source based on input image information; power source sections 81 and 82; a box 4 for housing the optical unit 50, the light source unit 66 and the power source sections 81 and 82; and a cover member 5 for entirely covering at least an upper surface of the box, wherein an outlet for externally exhausting air in the box by using axial fans 70 and 71 is provided only on a bottom side of the box 4. Liquid crystal panels 63R, 63G and 63B, which are held by the optical unit frame 50a, absorb the illumination light from the light source 66 and thus have different increased temperatures. Cooling air blown through an outlet 40p of a sirocco fan 40 that is directly connected to the optical unit frame 50a is divided by a cooling air reservoir 41 and a distribution sheet 43 into predetermined air quantities in accordance with the temperatures of the liquid crystal panels 63R, 63G and 63B so that the quantities of air obtained by the division are directly sent to the liquid crystal panels 63R, 63G and 63B.
