Patent CA-2182597-A1 (CA)
Title: Gain controlled optical fibre amplifier
Inventor: MASSICOTT JENNIFER
IPC: H01S3/06
Filed: 1995-02-20
Abstract: In a gain-controlled erbium-doped optical amplifier, gain control is achieved by clamping the gain of a laser cavity to be equal to the overall cavity loss and by fixing the resonant wavelength of the amplifier to be at a first wavelength.  When an optical signal to be amplified having  a  second  wavelength  different from the  first  wavelength passes  through the amplifier the  gain  experienced by the  signal depends entirely on the gain of the cavity, and not on the intensity of the signal.  If the first wavelength is arranged to be at the peak of the sum of the absorption and emission cross sections of erbium, the amplifier exhibits minimum sensitivity to ambient changes in temperature.

Abstract: Compatibilized blends of a biodegradable hy-drophobic polyester, unmodified starch or other sim-ilar polysaccharide containing less than 1 % water by weight, other biodegradable polymers that may be hydrophobic, plasticizer, and other additives. The blends are produced in the absence of water.  The preferred polyester polymer is poly(-caprolactone) and the preferred starch is from corn.  A small amount of a unique stretching agent is incorporated to provide high elongations at break, especially in film-forming compositions containing a significant amount of starch.  The starch is a discontinuous phase that may be completely or partially plasticized and the polyester polymer is the continuous phase.  The preferred polymers have unique film-forming proper-ties and are resistant to water and moisture.

Title: Laminated foam sheet and the molded body thereof for vehicle interior
Inventor: NAMURA KIYOYUKI
IPC: B32B7/027
Filed: 1996-12-27
Abstract: A laminated foam sheet for a car interior comprising a foamed core layer of modified polyphenylene ether resin (I) and film layer(s) of thermoplastic resin laminated thereon is disclosed. A glass transition temperature of the thermoplastic resin of the film layer is lower than that of the modified polyphenylene ether resin (I) of the foamed core layer. This makes it possible to produce molded bodies in a simple procedure using the laminated foam sheet. Since the molded bodies produced in accordance with the invention have superior characteristics with respect to heat resistance, rigidity, light weight and heat insulation, they can be advantageously used in car interiors, such as the material for the headliners and door trims. The advantage is an inexpensively produced molded material that is light in weight and very stable, even after prolonged exposure to elevated temperatures such as those that develop in a closed car parked in full sun.

Patent CA-2198865-A1 (CA)
Inventor: VLADIMIRSKY YULI
IPC: G03F7/26
Filed: 1994-09-09
Abstract: A method is disclosed for the manufacture of microstructures and devices. The method is relatively easy to implement, and has the capability to produce features having a resolution of ten microns or smaller with a high aspect ratio (60, 75, 100, 200, or even higher). A master mask, appropriately designed and fabricated, is used in an initial exposure step with visible light, ultraviolet light, x-rays, an electron beam, or an ion beam to make a "transfer mask" directly on the surface of the sample. It is not necessary to produce an expensive x-ray master mask, even if x-ray exposure of the sample is desired. There is no necessity for gap control during exposure of the resist through the transfer mask. The resulting structures may, if desired, have a higher aspect ratio than microstructures that have previously been produced through other methods. The "transfer mask" is not a unit separate from the sample, but is formed directly on the surface of each sample. A  conventional-type master mask is used to form the "transfer mask" with visible light, ultraviolet light, x-rays, an electron beam, or an ion beam. The total cost is determined primarily by the cost of the master mask. Because the master mask can be a conventional-type optical mask, the high cost of producing a conventional x-ray mask can be avoided. The "master mask" is used to form a "transfer mask" on each sample individually. The patterned transfer mask comprises a thin layer of an absorber of the radiation to be used in the final exposure. For example, if the final exposure is to be performed with soft x-rays, the transfer mask may be formed from an x-ray absorber such as a patterned layer of gold. The transfer mask is then used in one or more separate exposures of the underlying resist. An analogous method may be used for radiation-assisted chemistry, such as etching or deposition, on the surface of a sample.

Inventor: MUELLENBERG RALPH
IPC: F16D1/09
Filed: 1995-07-12
Abstract: The tensioning assembly serves for connecting an outer component (2) to a shaft (1). It comprises a double conical ring (20 [sic]) with a cylindrical circumferential surface and two conical surfaces which are arranged opposite one another, and also comprises two further conical rings (30 [sic] [lacuna]) which each have a conical circumferential surface which interacts with one of the conical surfaces of the double conical ring (20 [sic]). Axial tensioning screws (5) and axial forcing screws are distributed at regular spacings (8) over the circumference of a pitch circle, the forcing screws being arranged at the same spacings (8) in the positions of tensioning screws (5), instead of the latter. At one location, one tensioning screw (5) is provided outside the spacings (8, 8, 8) in order to ensure the correct arrangement of the conical rings on the double conical ring (20 [sic]) in the circumferential direction.

Title: Extended frequency range relaxation oscillator with improved linearity
Inventor: HASHJANI TIRDAD SOWLATI
IPC: H03K3/0231
Filed: 1997-04-03
Abstract: A relaxation oscillator, such as a voltage controlled oscillator (VCO), with automatic swing control feedback which dynamically monitors the voltage swing across a capacitor and adjusts the oscillator threshold voltage, at which reversal of the polarity of the charging/discharging current occurs, to maintain the effective voltage swing at a constant level. The improved relaxation oscillator provides a very wide linear range of frequency variation versus control voltage (or current) and allows for the extendibility of linear operation to or near the maximum frequency that can be practically achieved by the oscillator circuitry.

Patent CA-2203856-A1 (CA)
Title: Apparatus for dispensing tablets
Inventor: LEWIS GRAHAM
IPC: A61J7/02
Filed: 1997-04-28
Abstract: Automatic medication tablet dispensing apparatus, featuring a system capable of authenticating in real-time every tablet that is being counted to reduce the likelihood of errors in the prescription, particularly in the nature of the drug being dispensed. The apparatus includes a scan gate through which every tablet that is being dispensed passes. The gate generates data that is processed to assess the volume of the tablet.  The volume value is compared with a reference volume stored in memory.  In the absence of match, an error flag is raised an the tablet dispensing operation is terminated. To further reduce the  likelihood of  errors,  the  system is designed to enable the tablet dispensing function only when the identity of the drug to be delivered has been entered twice,  a first time on a keyboard,  and a second time by scanning the bar-code on the medication master container. Moreover, the apparatus is designed to calculate the total volume of the prescription and to indicate the size of the container that can hold the counted tablet load.
