Abstract: A freestanding mailbox is illuminated through the structural support post by an internal light source. A support element having an at least partially translucent section is coupled to a mailbox head. An illumination source is optically coupled to the support element, wherein the at least partially translucent section of the support element is illuminated by the illumination source. As the illumination source is optically coupled to the support element, the support element and/or mailbox head may be replaced if damaged without having to replace the illumination source.

Abstract: An apparatus for removing contaminants from a display device using an auxiliary chamber, and a method for attaching the auxiliary chamber to the display device. In one embodiment, an auxiliary chamber is adapted to be coupled to a surface of a display device. The auxiliary chamber is adapted to be coupled to the surface of the display device such that contaminants within the display device can travel from the display device into the auxiliary chamber. The auxiliary chamber further includes a getter which is disposed therein. The getter is adapted to capture the contaminants once the contaminants travel from the display device into the auxiliary chamber. In so doing, the present invention eliminates the need for getter material to be placed within the active area of the display device. As a result, the present invention increases the usable amount of space available within the display device. This extra space can then be utilized by features such as, for example, additional field emitters.

Abstract: A front-end surface illumination device is provided which is high in visibility when it is illuminated or not, low in power consumption, and compact. When a light beam emitted from an organic electroluminescence element formed on an end face of a light transmission plate reaches projecting portions, the light is emitted from the light transmission plate, and irradiated on an illuminated object. In this constitution, the light transmission plate has the function of projecting the light beam to the illuminated object, and transmitting the light beam reflected by the illuminated object with little diffusion.

Abstract: A field ion display device comprises a field ion emission plate, a microchannel plate and a fluorescent display plate, said plates being parallel to each other, with gaps there between, and being peripherally sealed with a thin gas filled inside. The device is addressed by X-Y encoding. When a signal is applied to an addressed point, positive ions are emitted from the corresponding point on the emission plate based on the signal strength, pass through the microchannel holes, impinge on the wall of the holes, so that the emission of the multifold secondary electrons is multiplied. Said secondary electrons are accelerated by the accelerating electrode, converted into a strong electron flow, extracted from the other side of the holes, again accelerated by the screen electrode, and finally bombard a corresponding pixel on the screen, thereby forming an image. The image has the advantage of good quality, high efficiency and low cost.

Abstract: A vehicular head lamp enables rotation of an upper reflector (1) relative to an intermediate reflector (2), thereby changing a dispersed light-distribution pattern (WP) with respect to a fixed reference light-distribution pattern (LP and HP). By causing a lower reflector (3) to rotate relative to the intermediate reflector (2), a collimated light-distribution pattern (SP) is changed with respect to the reference light-distribution patterns (LP and HP). The result of this arrangement is an improvement in visibility when the vehicle negotiates a curve.
