摘要： There is provided a heat conductive portion for conducting heat generated by an LED light source to cooling liquid at a rear side of each LED light source. Each heat conductive portion is connected one another with a pipe, and the cooling liquid flowing in the pipe is sequentially circulated through each heat conductive portion. A heat generation amount of an LED light source for red light is the smallest, the heat generation amount of an LED light source for green light is the largest, and the heat generation amount of an LED light source for blue light is the middle of the two. The cooling liquid cooled by passing through a radiation fin is firstly supplied to the heat conductive portion for the LED light source for red light, secondly supplied to the heat conductive portion for the LED light source for blue light, and lastly supplied to the heat conductive portion for the LED light source for green light. The cooling liquid discharged from a pump is supplied to the heat conductive portion for the heat conductive portion for the LED light source for green light. Then, the cooling liquid from this heat conductive portion passes through the pipe to be supplied to the radiation fin (radiator).

摘要： An optical position of a display device with respect to an optical axis of a projection optical system is displaced in a direction perpendicular to the optical axis in accordance with a change in the size of a projected image. For instance, a transparent flat plate is disposed in front of a projection lens, and the transparent flat plate is tilted in association with a rotation of a zoom adjustment ring. As the transparent flat plate is tilted, the apparent position of the display device relative to the projection lens is displaced in the direction perpendicular to the optical axis of the projection optical system. Thereby, the projected image on a screen is located at a proper position corresponding to a zoom state. Tilt control of the transparent flat plate is realized by a cam mechanism, for instance.

摘要： An ion wind generator is provided behind a light source. The ion wind generator 20 negatively-ionizes air by corona discharges using needle-shaped electrodes on the negative side, and draws the negatively-ionized air by a mesh electrode on the ground side to generate an air current. An exhaust port is provided with an ozone decomposition catalyst filter. A path axis for vent holes in the ozone decomposition catalyst filter is inclined to the direction of advancement (a direction toward the exhaust port) of unnecessary light from a lamp from the light source, and the unnecessary light from a lamp is shaded by the ozone decomposition catalyst filter.

摘要： A blade included in an impeller is formed so that, when viewed in a vertical cross-sectional view of the blade, a pressure surface of the blade and a suction surface of the blade opposite to the pressure surface are curved more in the direction in which the impeller rotates, in their areas farther from the axis of rotation of the impeller and closer to the exterior of the blade, and are arched so that a portion near the center of the blade is most distant from a straight line connecting the inner end and the outer end of the blade, the pressure surface and the suction surface form a curved surface including at least one circular arc, and a straight portion of the blade is formed to be connected to the curved surface on its one side, and extend toward the inner end of the blade on its other side.
