摘要： An information storage system utilizing an acoustic medium having its surface subdivided into a plurality of individually isolated acoustic transmission channels upon which a plurality of transmit and receive transducers are selectively placed. Each respective transmit transducer is electrically excited by a signal containing information from at least a preselected one of a plurality of data sources in order to cause a resultant acoustic stress wave to be propagated upon the surface of the medium within the associated acoustic transmission channel until the resultant stress wave is converted by an associated receive transducer into a plurality of charges which, in turn, are applied to a data source which, on command, either selects a new data to be stored or the old data that was circulated to be reconstituted into a transmit format to be recirculated within the associated acoustic transmission channel of the system.

摘要： Apparatus and method for forming metal grids. The apparatus includes a support, carriage, photomask, photolamp, and interferometer. A photographic plate is positioned on the support and the photomask is attached to the carriage which is translated to thereby carry the photomask across the photographic plate. The interferometer allows repetitive exposure of the plate by the photolamp via the photomask by measuring the position of the carriage and by controlling a photolamp trigger circuit for flashing the photolamp when predetermined carriage positions are sensed by the interferometer. The photomask contains a single slit through which light rays from the photolamp pass whereby the successive flashing of the photolamp is operative to form a pattern of parallel, closely spaced image patterns in the photographic plate. The thus exposed photographic plate is developed and the resultant photographic master is replicated in a sequence of steps resulting in the formation of a metal grid on a target substrate. Salient features of the apparatus and method contribute to the successful provision of metal grids characterized by substantially uniform spacing between parallel adjacent grid lines which increases the range of applications in which the grids can be utilized.
摘要翻译：用于形成金属网格的装置和方法。该装置包括支架，托架，光掩模，光电管和干涉仪。照相板定位在支撑件上，并且光掩模附接到滑架，滑架被平移，从而将光掩模携带在照相板上。干涉仪允许通过光掩模通过测量滑架的位置并通过控制用于在由干涉仪感测到预定的滑架位置时闪光照明灯的照明灯触发电路，通过光掩模重复地曝光该光板。光掩模包含单个狭缝，来自光电管的光线通过该狭缝通过，由此照相灯的连续闪烁可操作以在照相板中形成平行，紧密间隔的图案图案。将如此曝光的照相板显影，并且所得照相母版以一系列步骤复制，导致在靶基底上形成金属网格。该装置和方法的显着特征有助于成功地提供金属网，其特征在于平行的相邻网格线之间的基本上均匀的间隔，这增加了可以利用网格的应用的范围。

摘要： Electrode surfaces are coated with a passivating material (silicon dioxide, aluminum oxide or titanium dioxide) or with a reflecting material (chromium or chromium and gold) or with a special alignment material (carbon) using standard vacuum sputtering, vacuum evaporation, electrodeposition, or chemical vapor deposition techniques. After sufficient thickness of material has been deposited, the substrate is exposed to a broad or narrow beam of neutralized argon ions of a few kilo-electron-volts energy. The beam of argon ions is incident at a grazing angle to the surface, typically 20 DEG . Exposure of the overcoating results in a microscopic condition believed to comprise a "corrugated" surface with "ridges" and "valleys" parallel to the direction of the incident beam. These microscopically fine grooves or streaks are (1) reproducibly effective in causing parallel alignment of the liquid crystal molecules, (2) are durable to repeated cleaning procedures and air-bake treatments, and (3) are amenable to production applications in conjunction with vacuum deposition equipment.

摘要： A substrate (20) is treated prior to use to induce a near-perpendicular orientation of a liquid crystal director (26) relative to the substrate. A layer of silica (38) is deposited upon the substrate (20) by in-line magnetron sputtering as the substrate (20) is moved past the sputtering target (78), and the silica-coated substrate (20) is thereafter treated with a long-chain alcohol. The alcohol-treated substrate (20) is covered with a layer of liquid crystal (22), the director (26) of the liquid crystal (22) assuming a field-off state tilted about 1-3 degrees from the perpendicular toward an azimuthal direction (30) parallel to the direction of movement of the substrate (20) during deposition.

摘要： A process is provided for modifying a surface of a large area, non-planar substrate (10) to form micro structures (22) therein that alter its optical properties. The process comprises forming the micro structures by reactive ion beam etching through a chosen pattern that has been prepared on the surface.
