Patent CA-1279171-C (CA)

Abstract: METHOD AND APPARATUS FOR CONSTRUCTION OF BUILDINGS  TO GIVE THE APPEARANCE OF FULL LOG CONSTRUCTION            Abstract of the Disclosure Apparatus and method for construction of buildings to give the appearance of full log construction. Conventional wall studs are assembled in basically a conventional manner except that the corner is assembled in an "open" manner rather than the usual "closed" assembly, so that the corner studs form a V which opens toward the outside of the building.  A corner block assembly, having been pre-assembled, is then inserted into this open corner.  The corner block assembly extends vertically coexten-sively with the height of the corner of the building.  It is constructed of vertical studs and log blocks attached horizon-tally to these studs.  The log blocks are arranged so as to alternately protrude, first from one side and then from the other, each log block being perpendicular to the block above it and the one below it and to the stud to which it attached.  One side of each log block is aligned with the outer edge of the stud to which it is attached.  The side of each log block oppo-site the side aligned with the studs is curved in a cylindri-cally convex shape, except for a portion where the cylindrically convex surface is cut off so that the log block fits flat against the respective parallel stud.  Siding is then applied to the building, and alternating portions of siding extend beyond the corners coextensive with the log blocks.  The outer side of the siding is also cylindrically convex, so that the log blocks and matched siding give the appearance of full log construction, with all the advantages (insulation, weatherproofing, etc.) of conventional frame construction.  In one embodiment the siding intersecting each log block is cut off concave so as to match the cylindrically convex outer surface of the log block.  In another embodiment the portion of the log block where the cylindrically convex shape is cut off is extended beyond the respective parallel stud so as to accommodate the intersecting siding fitting against the flattened area.  The intersecting siding is cut off flat so as to fit against the extended flat-tened area, again providing a good weatherseal.

Title: Semiconductor heterointerface optical waveguide
Inventor: ALFERNESS RODNEY C
IPC: H01S5/323
Filed: 1988-05-10
Granted: 1992-08-18
Abstract: Abstract Low loss semiconductor waveguides for supporting propagation of optical signals over a wide range of wavelengths are achieved by growing at least two epitaxial layers of dopant material contiguous along a major surface of each layer to form a heterointerface therebetween. At least one of the epitaxial layers includes a sufficient concentration of semiconductor material to cause strain via lattice mismatch substantially at and near the heterointerface. The strain induces a change in refractive index such that the heterointerface exhibits a substantially higher refractive index than a portion of each epitaxial layer proximate to the heterointerface. The resulting waveguide is capable of supporting propagation of optical signals substantially along the heterointerface. In one example, contiguous epitaxial layers of InP and InGaP form a waveguide for optical signals at wavelengths greater than 0.93 µm. The concentration of Ga in the InGaP epitaxial layer is varied from 1018 to 1020cm-3 to increase the refractive index difference between the heterointerfaceand the immediate surrounding layers.

Abstract: ABSTRACT           A system for switching information packets assigned with two levels of semantic priorities between entering time multiplex lines and outgoing time multiplex lines, the read address of a packet in a buffer memory of a switch being stored in a queueing file associated with an outgoing port intended to transmit the packet.  The read address is accompanied by a bit which defines the priority level of the packet.  Each queueing file is comprised of two zones in series between the input and the output.  Means is included for writing in the first zone only when the second zone is full, the first zone is accessible only to high priority level packets between the reading of files.  The read addresses of low priority level packets, which were stored earlier than the read address of high priority level packet the oldest still being present in the file, is overwritten in equal number, at a maximum, to the number of read addresses stored in the first zone.

Title: Alias address support
Inventor: VAN LOO WILLIAM
IPC: G06F12/10
Filed: 1988-09-16
Granted: 1992-05-19
Abstract: ABSTRACT    An apparatus and method for resolving the problem of alias addressing in virtual memory systems which employ write back caches.  Specifically, in virtual memory systems aliasing can occur.  Aliasing occurs when there is a possibility that multiple virtual memory addresses will map to the same physical memory address.  This condition can result in the data at the common physical address in main memory including only a portion of the modifications made by the central processing unit or input/output device into the several cache locations.  The subject application resolves this conflict for addresses located within the operating system using one method and for addresses other than operating system addresses using a second method.
