    Abstract: PROBLEM TO BE SOLVED: To make completely buildable a display assembly by setting a manufacture mode for absorbing bending stress generated in a heat pipe before a computer is assembled. SOLUTION: The hinge structure 40 has a winding type tubular part 46 forming an opening 48, which is extended having a clearance around an end part 52 of an auxiliary heat pipe 50, thereby enabling the auxiliary heat pipe 50 to rotate on a hinge 40. A part of a heat-conductive member 26 forming a bent part or a flange 34, a bent part of the hinge 40, or the flange part 60 is placed in the manufacture mode for absorbing the bending stress in the auxiliary heat pipe 50 by extending the rotary shaft of the auxiliary heat pipe 50 on the same line with the rotary shaft of a machine hinge before an upright type computer is assembled.

    Abstract: PROBLEM TO BE SOLVED: To provide a cooling mechanism which effectively remove heat from a electronic device with minimal amount of sound while occupying minimal amount of space within the device. SOLUTION: The cooling mechanism 10 comprises a heat sink 54, a first conduction device 32 and convection device 34. The first conduction device conducts heat from a heat source to the heat sink 54. The convection device 34 has a first side 48, a second side 50 and a peripheral dimension. The heat sink 54 is disposed about the peripheral dimension of the convection device. The convection device 34 draws in air 46 through the first side 48 and second side 50 and forces the air 52 radially outward across the heat sink 54. A cooling mechanism 10 is also provided wherein the cooling mechanism has a ratio of heat removal in watts to volume in cubic centimeters from about 1:1 to about 3:11 at a sound level of between about 20 and 40 decibels.

    Abstract: An optical system is described consisting of reflection birefringent light valves, polarizing beam splitter, color image combining prisms, illumination system, projection lens, filters for color and contrast control, and screen placed in a configuration offering advantages for a high resolution color display. The illumination system includes a light tunnel having a cross-sectional shape corresponding to the geometrical shape of the spacial light modulator to optimize the amount of light projected onto the screen.

    Abstract: A liquid crystal element, a packaging structure providing thermal and alignment control, a display device including the same, and methods of fabrication and assembly are provided. The liquid crystal element includes: a semiconductor wafer, having microcircuitry and an array of reflective pixels; a layer of electro-optical responsive liquid crystal medium, of uniform thickness, disposed on the reflective pixels; a transparent conductive layer positioned on the liquid crystal, being substantially parallel to the reflective layers, to ensure a uniform thickness of the liquid crystal; and an insulative transparent layer provided on the conductive layer. The liquid crystal element is laminated to an optically flat substrate to limit the out-of-plane distortions thereof. The structure formed by element and substrate are disposed in a substrate holder which is mounted to a wiring board, and coupled to voltage sources for actuating the liquid crystal. During mounting, an aligning fixture is used to ensure proper orientation of the element relative to the related optical elements. Once the element is positioned, a heat sink is coupled to the rear surface of the substrate holder to dissipate heat.
