Patent CA-2149929-A1 (CA)
Inventor: FLEMING DEBRA ANNE
IPC: H01F41/04
Filed: 1995-05-23
Abstract: The present invention provides novel devices including magnetic components and novel methods for making them. In a first aspect, the invention provides a device comprising a metallized magnetic substrate (e.g., 5) having anaperture (e.g., 50). At least one metallized path (e.g., 20) passes through the aperture and around a portion of the substrate to define a magnetic component which has aflux path in the plane of the substrate and substantially confined within the substrate. The winding can pass around a substrate edge or through a second aperture. Advantageously, other circuit elements such as metallized interconnects (e.g., 55) and electronic components (e.g., 401) are disposed on the substrate to form a device. In a further aspect, the invention provides methods for metallizing magnetic substrate to form devices including magnetic components. In one embodiment, a green ceramic body (e.g., 5) comprising at least one ceramic layer is provided in an unfired state. At least one aperture (e.g., 50) having at least one conductively coated side wall pathway (e.g., 56) is formed within each ceramic layer. Top and bottom surface portions of the ceramic body are metallized such that the metallized surface portions (e.g., 20) form a continuous conductive region with the side wall conductive pathway to create a conductive winding about the ceramic body. The ceramic body with the conductive winding formed thereon is fired to yield a substrate including a magnetic component. Preferably after sintering, additional metal is plated on the conductive regions to enhance current-carryingcapacity.
Patent CA-2150095-A1 (CA)
Inventor: MAJKOVIC DAVOR
IPC: E21B17/10
Filed: 1995-05-24
Abstract: A drill bit reamer stabilizer has an upper and lower stabilizer on a bottom hole assembly with the lower stabilizer as close as possible to the drill bit.  This arrangement reduces deviations when drilling a straight hole.  Furthermore there is a reamer portion at the leading edge of the lower stabilizer to ensure the drilled hole is reamed out to the nominal drill bit size regardless of drill bit wear.  The assembly has a longitudinal shaft with a shank on a top end for connection to a drilling string, an internally threaded box in a bottom end of the shaft for connection to the drill bit, the internally threaded box having an internally tapered lip to overlap a drill bit shank.  The lower stabilizer has spiral flutes and lands adjacent the bottom end of the shaft, the flutes have polycrystalline diamond layer inserts at the leading edge of the stabilizer to provide a reamer, the inserts ream a hole substantially the same size as the nominal size of the drill bit.
Patent CA-2151102-A1 (CA)
Title: Computer based training system
Inventor: MARSH THOMAS GERARD
IPC: G06F13/00
Filed: 1995-06-06
Abstract: A training system (1) has various media for interfacing with a user. A system controller (2) uses an interface file (17) to automatically execute action commands to perform an interfacing event. The action commands are delimited by interactivity point commands, execution of which halts an execution path and allows interactive inputs. A simulation program (19) may then be retrieved to allow the controller (2) simulate interfacing of the training subject. Screen controls are dynamically linked with simulation handlers of the simulation program. They are all disconnected after use of a simulation program. A combination of automatic interfacing and interactivity is achieved in a simple way for effective user training.

Title: Automated histo-cytochemistry apparatus and encapsulation system for processing biological materials
Inventor: FARMILO A JAMES
IPC: G01N1/36
Filed: 1994-02-03
Abstract: There is disclosed an automated apparatus and process for immunocytochemical staining of biological materials using ligand pairing. The apparatus includes an array of sample cells interconnected with reagent supply and drainage lines. Each cell encloses a fluid chamber into which a sample substrate is inserted. The face of the substrate onto which a biological sample is mounted faces into a fluid well. The cell includes a cell head having a chamber to receive therein a solid support matrix releasably containing a ligand to be contacted with the sample. The chamber in the cell head is in flow communication with the fluid well so that when the ligand is released from the matrix it flows into the fluid well thereby contacting the mounted biological sample.  The ligand support matrix may be gelatin or wax. The cell body and cell head are differentially heated or cooled so that the mounted sample may be held at the preferred temperature for the reaction of interest and the cell head may be heated to a temperature sufficient to cause thermal degradation of the matrix to effect release of the ligand. Control electronics is provided for sensing and controlling the temperature of the various cell parts and for progammable control of reagent supply to the cells.

Patent CA-2155884-A1 (CA)
Inventor: MALACHOWSKI MICHAEL
IPC: G03G15/00
Filed: 1995-08-11
Abstract: An apparatus for advancing a sheet from a moving imaging member having an unfused image thereon after transfer of the image to the sheet. After the image is transferred to the sheet, the sheet is advanced by a transport to a fuser. The transport has low impedance, high air flow to draw the sheet toward the transport for acquisition. As the sheet is moved across the transport, an increased air flow impedance causes a low vacuum pressure in the transport to provide a low drive force that minimizes quality and motion disturbances on the sheet.

Title: Game play media lending machine, for which bank notes can be used
Inventor: TAKEMOTO TAKATOSHI
IPC: G07F7/04
Filed: 1994-05-13
Abstract: A bank note input from the outside is accepted for lending game play media. If change is to be given, a bank note is dispensed as the change. A bank note validation section (20a) takes in an input bank note, determines at least the denomination of the bank note, and outputs amount information. A bank note return section (20b) stores the bank note if it is a bank note that can be used for change, and is responsive to a change paying out command for dispensing a necessary number of bank notes as change to the outside, using the stored bank notes. A lending controller (70) uses dispensing control means (81 ) for inputting the amount information and is responsive to a lending command for outputting a command for dispensing game play media in a given dispensing unit. The lending controller uses operational means (82) for subtracting an amount corresponding to the dispensing unit from an amount indicated by the amount information to find the remaining amount. Return control means (83) outputs a change paying out command to the bank note return section if the remaining amount is not zero. A game play media dispenser (60) is responsive to a dispensing command for dispensing a predetermined number of game play media.
