Abstract: EFFICIENT ENCODING/DECODING IN THE DECOMPOSITION AND RECOMPOSITION OF A    HIGH RESOLUTION IMAGE UTILIZING   ITS LOW RESOLUTION REPLICA Abstract More efficient encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique prediction arrangement. The prediction arrangement determines whether high resolution pixels to be recomposed from low resolution pixels from a low resolution replica of the high resolution are so-called typically predictable or non-typically predictable by using general prediction rules. The general prediction rules are also employed to determine if any of the typically predictable high resolution pixels would be improperly recomposed. Such high resolution pixels which would be improperly recomposed are identified as exceptions. It is noted that so-called supplemental information is required to properly recompose non-typically predictable pixels and typically predictable pixels which are identified as exceptions. To this end, exceptions accompany the low resolution pixel for which the corresponding high resolution pixels would otherwise be improperly recomposed. (FIG. 1).

Filed: 1990-05-04
Abstract: ABSTRACT      A bundle of wallboard or plasterboard comprising perforated, or slit bundling tape permitting the bundle to be separated readily for use at the construction site.  In one embodiment, the bundling tape includes two parallel lines of perforations, or slits with the bundling tape being applied to edges of a wallboard bundle for shipping to the construction site.  Prior to the wallboard being placed within the structure, the bundling tape is simply peeled away along the perforations, or slits to permit separation of the wallboard from the bundle.  In another embodiment, a single line of perforations, or slits is formed in the center of the bundling tape at the interface of the two panels of wallboard forming a bundle.  The bundling tape is configured to permit separation of the panels of wallboard along the perforated, or slit line simply by pulling the panels of wallboard apart.  These configurations, and a method for manufacturing them, provide economical savings in material, manufacturing steps, and effort at the construction site.

Abstract: A method for controlling opening/closing of a door in an automatic door system comprises the steps of causing the door to conduct opening operation to its opening-stop limit by an initial opening signal transmitted after the power supply is put to work and the arrival of the door at its closing-stop point is confirmed, and measuring the opening stroke at that time; causing the door to conduct closing operation to its closing-stop point when it is stopped at opening-stop point and no opening signal is inputted, and measuring the closing stroke of the door at that time; computing the difference between the measured opening and closing strokes upon stopping of the door at its closing-stop point; and outputting a signal of abnormal condition if the difference is more than a preset value, or causing the door to conduct normal opening/closing operation if it is less than the preset value.  Thus, the opening/closing operation of the door can be made at a high speed by a preset distance in the beginning of the whole stroke, and thereafter at a low speed.

Title: Polymers containing halomethyl-1,3,5-triazine moieties
Inventor: BONHAM JAMES A
IPC: C08F8/30
Filed: 1991-01-16
Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to photosensitive compounds, more particularly polymers containing halomethyl-1,3,5-triazine moieties and to radiation-sensitive compositions and elements utilizing these polymers.  Migration typically occurs in photopolymerizable compositions containing low molecular weight monomers and plasticizers, which tend to diffuse between layers, carrying along other ingredients such as the photoinitiator.  This invention provides radiation-sensitive organo-halogen compounds that have a photo-labile halomethyl-1,3,5-triazine moiety and a polymeric moiety within the same molecule.  The compounds of this invention are comprised of a polymeric moiety having attached or incorporated within its structure at least one 1,3,5-triazine nucleus, said triazine nucleus having at least one halomethyl substituent attached to a carbon atom of the triazine nucleus.  These compounds are capable of being stimulated by actinic radiation at wavelengths of from about 250 to about 900 nanometers to generate free radicals and/or acids.  The compounds of this invention are useful as photoinitiators in free radical polymerization reactions, oxidation-reduction reactions, or reactions sensitive to acid, and they also exhibit the capability to crosslink upon exposure to light.  The polymers of this invention are less susceptible to migration on account of the anchoring or ballasting of the halomethyl-1,3,5-triazine.

Title: Melting glass with oxidation control and lowered emissions
IPC: C03B5/173
Filed: 1991-04-05
Abstract: Premature dissociation of fining agent is avoided in a glass melting operation while controlling the final redox state of the product glass by initiating the melting process under relatively oxidizing conditions and subsequently altering the redox conditions to make the glass more reducing.  A glass that is more reduced than usual can thereby be produced without sacrificing the ability to adequately fine the glass.  For a given redox level, less fining agent need be used, thereby lowering emissions from the melting operation, because dissociation of the fining agent is delayed until a later stage of the process where the redox conditions are changed.
