摘要： In a particular embodiment, the fractional coverage louver device includes a transparent layer of material having a first surface and a second surface parallel thereto. A plurality of louver members disposed within the transparent layer of material provide fractional reflective coverage across the width of the transparent material. The louver members are aligned to receive light entering the first surface at a shallow angle relative to the first surface and direct the light out the second surface at a high angle relative to the second surface, thereby increasing the angular viewing range. Transparent areas between louver members allow a portion of incident ambient light to pass through the louver device without being reflected back to a viewer. As such, the louver device has advantageous contrast properties.

摘要： An information storage unit functioning in a vacuum is provided wherein a data storage medium has an information storage area for storing and reading information thereon. An array of electron beam emitters is spaced from and in close proximity to the data storage medium for selectively directing a plurality of electron beams toward the data storage medium. Focusing optics between the array of electron beam emitters and the data storage medium focus each of the electron beams on one part of the information storage area of the data storage medium. A micro electromechanical motor associated with the data storage medium moves the data storage medium relative to the array of electron beam emitters, so that each of the emitters directs an electron beam selectively to a portion of the information storage area to read or write information therein. Electronic circuitry spaced from and in electronic communication with the array of electron beam emitters controls the operations of the array of electron beam emitters. A vacuum device in the information storage unit maintains the vacuum between the data storage medium and the array of electron beam emitters.

摘要： A thin film recording head which utilizes polyimide as the coil encapsulant. The polyimide encapsulant is self planarizing and lends itself to processing of the coil vias, magnetic shunt vias and apex tapers. Methods of fabricating a thin film recording head and forming coil vias, magnetic shunt vias and apex tapers are also disclosed. In general, an insulating material is deposited on a bottom magnetic yoke. A first layer of polyimide is then deposited of the insulating material. Then, a three layer photoresist structure is deposited on the first layer of polyimide, which includes a transfer layer deposited between two layers of photoresist. The top layer of photoresist is developed and the transfer layer is etched. The first layer of photoresist is then etched into the polyimide layer to form troughs therein. The coil material is then deposited into the etched troughs. The coil material comprises a layer of metal having a relatively thin passivation layer deposited thereover. The photoresist and transfer layers and unwanted coil material are then removed by ultrasonic agitation in acetone. A second layer of polyimide is then deposited over the formed coil structure to encapsulate and planarize it. The method which forms the coil vias, magnetic shunt vias and apex tapers of the recording head after formation of the encapsulated coil comprises the following steps. First, a photoresist layer is deposited on top of the second layer of polyimide. The photoresist layer is then patterned to define coil vias, magnetic shunt vias and apex taper locations. Then, this structure is heated to a temperature less than 120 degrees Celsius to round the corners of the photoresist layer at the coil via, magnetic shunt via and apex angle locations. Finally, the patterned photoresist layer and underlying polyimide layer are etched to provide the coil vias, magnetic shunt vias and apex tapers. Thereafter, the top magnetic yoke is deposited over the encapsulated structure to complete the thin film magnetic recording head.

摘要： A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

摘要： In a particular embodiment, a see-through display includes a screen having transparent layer of material with a front side and a back side. At least one plurality of shaped louver members is disposed between the front side and the back side. The plurality of the louver members allow transmission of a fraction of light through the screen with minimum scattering within a range of incident angles. The plurality of the louvers also redirect image signal light from an image source into a range of angles centered about a normal to the screen. The louver members combine the image signal light with the light emitted from background objects located on the backside of the screen. The background image light is transmitted through the display screen with minimal scattering. For embodiments providing two sets of louver members, the image signal light may be redirected to observers on either side of the screen, such that the observers may see each other as well as the intended image.
