Abstract: In an image pick-up mode, when a piece of image information is picked-up by an image information acquisition unit (1), pieces of position information acquired by a position measurement unit (2) are stored in a storage unit (4) together with the pieces of image information in association with each other. In a playback mode, when the scroll key of a key input unit is kept pressed for a predetermined time or more, pieces of position information stored in the storage unit (4) in association with pieces of image information are sequentially read out. An arithmetic unit (6) sequentially calculates the distance between pick-up points of two pieces of image information, and a search unit (7) determines whether the calculated distance is equal to or longer than a predetermined distance acquired by a condition acquisition unit (5). When the search unit (7) searches for a calculated distance equal to or longer than the predetermined distance, a display control unit (8) displays, on a display unit (9), a searched item of image information, i.e., a piece of image information picked-up at a place apart from the image pick-up place of immediately preceding item of image information by the predetermined distance or more.

Title: A process and method employing dynamic holographic display medium
Inventor: KEKAS DENNIS JASON
IPC: G09F19/12
Filed: 2000-05-23
Granted: 2004-03-11
Abstract: Conventional display technology can be used to display crude computer generated holograms (CGH), and can be extended to moving displays. However, the ones best suited from the standpoint of illumination flexibility, such as the common liquid crystal displays (LCDs), switch very slowly. Thus systems with far better dynamic-rapid response requires very complex drive electronics. A non-memory ceramic PLZT, dynamic holographic display medium, provides much faster response time relative to common LCD technology. This system, which is the major embodiment of the present invention, also exhibits good spatial display capability. The system of the present invention, can display fast Fourier transformation (FFT) computer generated holograms (CHHs); thus allowing the use of FFT based manipulation of images. By using a delta image updating in Fourier space, the instant system will speed up image generation significantly; since it is often the case that an object's spatial frequency components change more slowly than its position.

Abstract: A two-step progressive thermal oxidation process is provided to improve the thickness uniformity of a thin oxide layer in semiconductor wafer fabrication. A semiconductor wafer, e.g., of silicon, with a surface subject to formation of an oxide layer thereon but which is substantially oxide layer-free, is loaded, e.g., at room temperature, into an oxidation furnace maintained at a low loading temperature, e.g., of 400-600 DEG C, and the wafer temperature is adjusted to a low oxidizing temperature, e.g., of 400-600 DEG C, all while the wafer is under an inert, e.g., nitrogen, atmosphere. The wafer is then subjected to initial oxidation, e.g., in dry oxygen, at the low oxidizing temperature to form a uniform initial thickness oxide, e.g., silicon dioxide, layer, e.g., of up to 10 angstroms, on the surface, after which the furnace temperature is increased to a high oxidizing temperature, e.g., of 700-1200 DEG C, while the wafer is under an inert atmosphere. The wafer is next subjected to final oxidation, e.g., in oxygen and/or water vapor, at the high oxidizing temperature to increase uniformly the oxide layer to a selective final thickness, e.g., of 20-100 angstroms, whereupon the resultant uniform final thickness oxide layer-containing wafer is recovered from the furnace.

Title: Thermally actuated microelectromechanical systems including thermal isolation structures
Inventor: MAHADEVAN RAMASWAMY
IPC: F16K31/00
Filed: 2000-11-24
Granted: 2004-06-21
Abstract: Microelectromechanical structures include a microelectronic substrate and spaced apart supports on the microelectronic substrate. A beam extends between the spaced apart supports and expands upon application of heat thereto, to thereby cause displacement of the beam between the spaced apart supports. The application of heat to the beam creates a thermal conduction path from the beam through the spaced apart supports and into the substrate. A thermal isolation structure in the heat conduction path reduces thermal conduction from the beam, through the spaced apart supports and into the substrate, compared to absence of the thermal isolation structure. The thermal isolation structure preferably has lower thermal conductivity than the beam and the supports. The heat that remains in the beam thereby can be increased. The thermal isolation structure may include a thermally insulating structure at each end of the beam, a thermally insulating structure in each spaced apart support, a thermally insulating structure in the substrate adjacent each spaced apart support, and/or at least one thermally insulating structure in the beam. Accordingly, improved thermal efficiency for microelectromechanical structures may be provided, to thereby allow lower power, higher deflection, larger force and/or higher speed.

Title: Method and apparatus for high-pressure wafer processing and drying
Inventor: BERGMAN ERIC J
IPC: H01L21/00
Filed: 2001-01-12
Granted: 2003-12-11
Abstract: A system for high-pressure drying of semiconductor wafers includes the insertion of a wafer into an open vessel, the immersion of the wafer in a liquid, pressure-sealing of the vessel, pressurization of the vessel with an inert gas, and then the controlled draining of the liquid using a moveable drain that extracts water from a depth maintained just below the gas-liquid interface.
