Title: A method for handling obscured items on computer displays
Inventor: BERQUIST DAVID T
IPC: G06F3/0481
Filed: 1995-04-12
Abstract: In the present invention, program code is executed in a data processing system in order to display a plurality of items so that each of the items is displayed as a different layer with respect to each of the other items and so that at least portions of items in lower layers are obscured by items in upper layers. Items may be, for example, icons, tool bars, directories, documents, notes, and or the like. Program code is also executed in the data processing system in order to select an item so that each of the other items, which is displayed in a layer above the selected item and which would otherwise obscure the selected item, is cut out in order to expose at least a portion of the selected item and so as to reveal an otherwise obscured portion of an item which is layered below the selected item. A cut-out border may be provided around the selected item so that an item layered below the selected item is revealed.

Title: Apparatus for inhibitively preventing birds from crowding
Inventor: OHBA TADAO
IPC: A01M29/26
Filed: 1996-12-31
Abstract: The  present  invention  provides  an  apparatus  for inhibitively preventing birds from crowding,  in which a wire-shaped member spanned between adjacent support columns will not slack or break, nor will support columns fall, even when the wire-shaped member is stepped on with shoes. The wire-shaped member is  tightly spanned between the adjacent support columns in a substantially horizontal direction.  Onto the wire-shaped member, magnetic members are disposed in regular spaced relationship.  At least one springy member is interposed between the support column and the wire-shaped member or along the wire-shaped member.  If the wire-shaped member is  stepped on with shoes,  the elasticity of the spring member absorbs the force and prevents the wire-shaped member from slacking or breaking.

Patent CA-2198413-A1 (CA)
Title: Improved extrusion track for blinds
Inventor: CHOU TSER-WEN
IPC: E06B9/36
Filed: 1997-02-25
Abstract: The improved system utilizes a track (51 ) which has a bowed internal surface to prevent the wheel of the carrier (17) from frictional engagement with the side of the track (51). The curved surface (55) which faces the wheels (27) will not be engaged by the wheels (27) even where the carrier (17) turns to one side or the other. This is accomplished while leaving the innermost portions of the raceway (53) in the same width position with regard to the wheels (27) as is usual to prevent the carrier (17) from coming off-track. The tolerances for the inner corners of the raceway (53) opposing the wheels (27) may be reduced to further prevent the possibility of jamming in the track (51).

Inventor: COLLINS RICHARD EDWARD
IPC: B32B37/30
Filed: 1995-09-28
Abstract: Vacuum glazings and methods of manufacture thereof are described; the glazings provide improved shear stress resistance in that the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating internal vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the pillars (5) consist of a core (13), made of a material of higher compressive strength, with at least one end covered by a layer of softer material (14). Alternatively,the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating vacuum, and an array of support pillars (5) placed between the glass sheets (2,3), wherein the array includes a small number of fused solder glass pillars located over the surface of the glazing, between pillars of higher compressive strength.  Advantageously the support pillars (5) comprise two flat parallel ends (15, 16) shaped to provide stable equilibrium, and sides (17) shaped to provide unstable equilibrium, to ensure that the pillars when placed on a glass sheet will fall onto one of the flat faces (15, 16) and thereafter lie on that face.
Patent CA-2202387-A1 (CA)
Inventor: ARKLES BARRY C
IPC: H01L21/77
Filed: 1995-10-10
Abstract: Titanium and titanium nitride layers can be produced by chemical vapor deposition (CVD) processes conducted at temperatures below 475 ·C. The layers may serve as diffusion and adhesion barriers for ultra-large scale integration (ULSI) microelectronic applications. The processes use a titanium halide precursor, such as titanium tetraiodide, and hydrogen or hydrogen in combination with nitrogen, argon, or ammonia to either produce pure titanium metal films, titanium films which alloy with the underlying silicon, or titanium nitride films. The deposition of titanium metal from titanium halide and hydrogen or the deposition of titanium nitride from titanium halide with nitrogen and hydrogen is achieved with the assistance of a low energy plasma.  The process allows smooth and reversible transition between deposition of films of either titanium metal or titanium nitride by introduction or elimination of nitrogen or ammonia.

Title: Power management system and method for maximizing heat delivered to dialysate in a dialysis machine
Inventor: LARSON BYRON
IPC: H02J3/14
Filed: 1996-06-06
Abstract: The amount of electrical power delivered to a dialysate heater in the dialysis machine is maximized without substantially exceeding a predetermined maximum allowed power comsumption for the dialysis machine. The instantaneous power consumed by the machine is measured (132) and compared to the maximum allowed power consumption (134, 136, and 138). The excess of power beyond the instantaneous power consumed up to the maximum allowed power consumption is then made available to the heater (142). The worst case power consumption limitations of the dialysis machine components do not adversely affect the heat available from the heater. The rate at which dialysis treatments may progress may increase or the time required for dialysis treatments may decrease.

Patent CA-2235091-A1 (CA)
Inventor: LAUTZENHISER LLOYD LYNN
IPC: H03L7/099
Filed: 1998-04-17
Abstract: A variable-deviation-sensitivity voltage controlled oscillator includes an AC voltage divider that selectively decreases deviation sensitivity. Above a pre-determined roll-off frequency, the AC voltage divider attenuates voltage spikes and other electrical noise, thereby decreasing undesirable incidental frequency modulation. Below the roll-off frequency, the voltage dividing function ceases, and full deviation sensitivity of the voltage controlled oscillator returns. When used in a phase locked loop,, the voltage controlled oscillator responds to loopfrequencies as well as modulation frequencies with decreased deviation sensitivity, thereby attenuating voltage spikes and other electrical noise, and thereby attenuating incidental frequency modulation. At loop control frequencies below the pre-determined roll-off, including DC, the oscillator responds at full deviation sensitivity thereby providing an unattenuated range of capture.
