Patent CA-2220922-A1 (CA)
Inventor: FUKUCHI AKIO
IPC: H03G3/30
Filed: 1997-11-12
Abstract: In an automatic predistortion adjusting circuit, a splitter splits an input signal into first and second signals.      A predistortion circuit applies first non-linear characteristics to the first signal, a variable attenuator adjusts an amplitude of an output signal of the predistortion circuit, a variable phase shifter adjusts a phase of an output signal of the variable attenuator, and a main amplifier amplifies an output signal of the variable phase shifter, so that second non-linear characteristics opposite to the first non-linear characteristics are applied to an output signal of the main amplifier. A directional coupler takes out a part of an output signal of the main amplifier as a branch signal, and a delay line delays the second signal. An adder adds a delayed signal passed through the delay line to the branch signal.      Further, a detector detects a strength of an output signal of the first adder, and a control circuit controls the first non-linear characteristics, an attenuation amount of the variable attenuator and a phase amount of the variable phase shifter in accordance with an output signal of the detector.
Patent CA-2223119-A1 (CA)
Title: Address counter cell
Inventor: BHULLAR GURPREET
IPC: G11C7/10
Filed: 1997-11-28
Abstract: An address counter cell for use in burst mode operation in a synchronous DRAM is described which, in response to a falling edge of a system clock, simultaneously loads address inputs into an external address master latch and an internal address master latch, and further enables a multiplexer to select between the external and internal address inputs.  In response to a subsequent rising edge of the system clock, the selected address input is then loaded into a low-output-load capacitance slave latch and is further provided to complementary output nodes.  The signal from one of the output nodes is also fedback to circuitry for incrementing the selected address internally for subsequent clock cycles remaining in the burst mode operation.  Once the initial address of the burst operation has thusly been entered, for the remainder of the burst mode, the multiplexer selects the address loaded into the internal address master latch and operates as an edge-triggered flip/flop with the master latch accepting an incremented address in response to the falling edge of the system clock and with the slave latch loading and outputting the incremented address in response to the rising edge of the system clock.  During a standby mode, circuitry is provided for disabling the counter cell and ensuring that the output nodes are stable and disabled.

Title: System and method for producing drug-loaded microparticles
Inventor: SMEDLEY MARK I
IPC: A61K9/16
Filed: 1996-06-06
Abstract: Method and system of producing microparticles loaded with biologically active drugs, including proteins such as ICAM-1, for controlled release of the drugs in a nasal passageway. The method includes introducing a drug/polymer feed solution and an emulsifier into a first mixing chamber to create an emulsion, then mixing a cross-linking agent together with the emulsion under controlled conditions to create microparticles loaded with the drug. The system includes a first mixing chamber, in which the emulsion is created, having a first port for introducing the drug/polymer solution, and a second port angled substantially perpendicular to the first port for introducing the emulsifier. A second mixing chamber adjacent to the first mixing chamber receives the emulsion and either contains a cross-linking agent or receives a stream of a cross-linking agent to solidify the microparticles.  The formed microparticles are filtered and deaggregated to form individual microparticles that then may be formulated for nasal passageway delivery.

Title: A modular optical cross-connect architecture with optical wavelength switching
Inventor: SABELLA ROBERTO
IPC: H04Q3/52
Filed: 1996-11-13
Abstract: An optical cross-connect node architecture interfaces plural optical fiber input and output links, each link containing plural wavelength channels. In one embodiment, the input links are connected to an optical coupler. Pairs of tunable optical filters and optical wavelength converters are each connected to an output port of the optical coupler and perform wavelength channel routing and switching in the wavelength domain, i.e., without the need for any optical space switch. In another embodiment, an additional input wavelength converter is connected to each input fiber link to convert the plural wavelength channels on each link to different, non-interfering wavelengths. This prevents wavelength contention in the optical coupler to which the input wavelength converters are connected. New fiber links may be added in modular fashion without significant impact on the pre-existing optical cross-connect structure. Similarly, new wavelength channels may also be multiplexed onto existing fibers to provide wavelength modularity without having to reconfigure the node.

Title: Method and apparatus for maldi analysis
Inventor: HIGGINS SCOTT
IPC: H01J49/04
Filed: 1997-09-19
Abstract: Matrix assisted laser desorption/ionization is performed in a manner to thermalize large analyte ions in a plume of desorbed material for spectroscopic analysis. The thermalized ions have a low or zero mean velocity and are presented at a well-defined instant in time, reducing artifacts and sharpening the spectral peaks. In one embodiment the light is delivered to a matrix or sample holder having a cover, baffle or compartment. The baffle or compartment impedes or contains a plume of desorbed material and the analyte undergoes collisions to lower its mean velocity and directionality. Thus "thermalized", the analyte ions are passed to a mass analysis instrument. In a preferred embodiment, an optical fiber butts up against a thin transparent plate on which the specimen resides, with the matrix side in a vacuum acceleration chamber. A mechanical stage moves the specimen in both the x- and y-directions to select a point on the specimen which is to receive the radiation. The use of a fiber optic illuminator allows the entire stage assembly to be subsumed essentially within the dimensions of a conventional stage.

Title: Npf rollers for conveyor idlers
Inventor: FUKS VLADIMIR
IPC: B65G39/04
Filed: 1998-10-13
Abstract: Roller is very common part for any kind of the materials handling equipment.  Some of the handling equipment, like Roller Conveyor, using the surface of the rollers to transport big lumps or boxes or other lumpy products. Other handling equipment, like Belt Conveyors, using the rollers as a supporting element for the moving belt. Most of the rollers have a shaft and a rolling shell supported by bearings.  Under the load of the handled material, the roller's shaft and the shell are deflected. The effect of the deflection is a function of the load and rigidity. When the load is higher the deflection getting bigger. The shaft of the roller is much more flexible than the shell and then the deflection of the shaft (under the same load) is higher than the shell. With increasing of the load, growing the difference of the deflection between the shaft and the shell.      Effect of the non-equal deflection creates few mechanical problems. One of the problems is, that the non-equal deflection (of the shaft and the shell) creates the angular misalignment of the bearings. The durability of the bearing is in inverse proportion to the angular misalignment. The bearing can function reasonably up to certain level of the angular misalignment. This limitation is accounted during the design of the roller. The second problem is, that during rotation of the shell (under the load) the unequal deflection (of the shaft and the shell) causes the pumping effect at the sealing area of the bearings. This effect is in direct proportion to the load on the roller. The pumping effect creates movement of the air through the labyrinth of the seals. Because of the existing pumping effect, all the rollers which are used in the dusty environment, required much more sophisticated seals in order to reduce the contamination of the bearing. The conventional design of the rollers, reduces but can not eliminate completely the pumping effect. The invention (Fig.5) used to overcome the above mentioned mechanical problems.
