Title: Method of packaging resiliently compressible articles
Inventor: GLADNEY RICKY F
IPC: B65B3/02
Filed: 1995-08-14
Abstract: A method of packaging a resiliently compressible article (10) comprises the steps of inserting the article into a tube of deformable material (22) such that excess material is provided at the ends of the tube. A first end (24) of the tube is then sealed closed. Air is then evacuated from the tube through the second end thereby deforming the tube around the article and causing the article to compress. While a vacuum is maintained in the tube, the second end of the tube is sealed closed. A containment sleeve (26) is fitted over the sealed tube to maintain the article in a compressed state. When the article is unpackaged, the containment sleeve is reversed and the tube is allowed to expand in a gradual controlled fashion by the bleeding of air back into the tube.

Title: Field electron emission materials and devices
Inventor: TUCK RICHARD ALLAN
IPC: H01J9/02
Filed: 1996-08-02
Abstract: A field electron emission material comprises an electrically conductive substrate (13, 14) and, disposed thereon, electrically conductive particles (11) embedded in, formed in, or coated by a layer of inorganic electrically insulating material (12) (e.g. glass). A first thickness (15) of the insulating material is defined between each particle (11) and the substrate (13, 14) and a second thickness (15) of the insulating material is defined between the particle (11) and the environment in which the material is disposed. The dimension of each particle (11) between the first and second thicknesses (15) is significantly greater than each thickness (15). Upon application of a sufficient electric field, each thickness (15) provides a conducting channel, to afford electron emission from the particles (11). By use of an inorganic insulating material (12), surprisingly good stability and performance have been obtained. The particles (11) can be relatively small, such that the electron emitting material (11, 12) can be applied to the substrate (13, 14) quite cheaply by a variety of methods, including printing.  The material can be used in a variety of devices, including display and illuminating devices.

Title: Thin film forming process
Inventor: OHMI KAZUAKI
IPC: H01L21/203
Filed: 1998-03-20
Abstract: A process for producing an SOI substrate is disclosed which is useful for saving resources and lowering production cost.  Further, a process for producing a photoelectric conversion device such as a solar cell is disclosed which can successfully separate a substrate by a porous Si layer, does not require a strong adhesion between a substrate and a jig, and can save resources and lower production cost.  In a substrate having a porous layer on a nonporous layer and further having on the porous layer a layer small in porosity, the nonporous layer and the layer small in porosity are separated by the porous layer to form a thin film.  A metal wire is wound around a side surface of the substrate, and a current is made to flow into the metal wire to generate a heat from the metal wire and transfer the heat preferentially to the porous layer, thus conducting the separation.  The separated substrate is used for producing an SOI substrate and the separated nonporous Si layer is reutilized in a process of producing an SOI substrate.

Patent CA-2235101-A1 (CA)
Inventor: RYAN JOHN O
IPC: H04N5/04
Filed: 1992-11-12
Abstract: A video-scrambling system induces a random wobble i.e., time shifting, in the location of active portion of the video frame, without affecting the horizontal sync signal and colorburst in each video line, thus providing both security and concealment.  The security is enhanced by filling in the gap between the nominal beginning of active video and the actual beginning of active video with a synthesized video signal which replicates the adjacent active video using a digitally generated filling pattern. Also, a random noise overlay further conceals the location of the gap.  Additional concealment is provided by wiggling in time the location of the horizontal sync signal using one or two frequencies and also by randomly altering the location of the vertical sync signal.  The NTSC digital encoding in accordance with the invention is simplified by using only two channels, chrominance and luminance, and by a heterodyne circuit for chrominance stability.  NTSC encoding is enhanced by providing detail normally lost, by use of the chroma channel.  Additionally, a non-standard video signal may be provided with a portion of the colorburst on the front porch of the horizontal blanking, thus allowing use of a relatively simple decoder.
