Patent CA-2312150-A1 (CA)
Inventor: IWAFUJI TAKAMI
IPC: H04B10/071
Filed: 2000-06-23
Abstract: In an optical transmitter, an oscillation wavelength of a semiconductor laser diode is controlled so as to stabilize the oscillation wavelength, while neither forward project light, nor a beam splitter is employed. The optical transmitter is arranged by employing: an optical waveguide path into which forward projection light of the semiconductor laser diode is entered; a wavelength filter containing an oscillation wavelength of the semiconductor laser diode in a wavelength band where a transmission wavelength band is transferred to a reflection wavelength band and vice versa, for causing a portion of backward projection light of the semiconductor laser diode to pass therethrough to output transmission light, and for reflecting the remaining light of the backward projection light to output reflection light; a first light receiving device for detecting a light level of the transmission light to output a transmission light level; a second light receiving device for detecting a light level of the reflection light to output a reflection light level; and a wavelength control circuit for controlling an oscillation wavelength of the semiconductor laser diode based upon both the transmission light level and the reflection light level.

Patent CA-2316340-A1 (CA)
Title: Phospholipids having antimicrobial activity with or without the presence of antimicrobials
Inventor: UTLEY MARYJANE
IPC: A61K31/66
Filed: 1998-11-20
Abstract: Phospholipids (e.g. MPPA and DPPS) show a remarkable antimicrobial effect against gram negative (e.g. Pseudomonas and Klebsiella) and gram positive (e.g. Staphylococcus and Enterococcus) bacteria. When the phospholipids are combined with antibiotics (e.g. ampicillin, ceftazidime, or piperacillin) the effect of the antibiotic is enhanced by the presence of the phospholipid. The substance of the invention will be used alone or in combination with antibiotics, antimicrobials, antifungal, antiviral, or antiprotozoal drugs for the combat of infectious diseases, such as prophylactic, cytocidal, antibacterial, bacteriostatic, and/or bacteriocidal effects.

Title: Improvements in the formation of brassica napus f1 hybrid seeds with high oleic acid content and a reduced linolenic acid content
Inventor: CHARNE DAVID G
IPC: A01H5/10
Filed: 2000-01-19
Abstract: An improved route is provided for producing seeds capable of forming a Brassica napus F1 hybrid via plant breeding wherein the vegetable oil of the seeds exhibits a highly elevated oleic acid (C18:1) content of at least 80 percent by weight (e.g. 80 to 86 percent by weight) and a reduced linolenic acid (C18:3) content of no more than 3 percent by weight (e.g. 1 to 3 percent by weight) based upon the total fatty acid content. The female parent plant (i.e., the seed parent) possesses a homozygous modified FAD-2 gene pair for elevated oleic acid production solely in either the A-genome or the C-genome, and the male parent (i.e., the pollen parent) possesses a homozygous modified FAD-2 gene pair for highly elevated oleic acid production in both the A-genome and the C-genome. Both parent plants also include at least one homozygous modified FAD-3 gene pair for reduced linolenic acid production. An endogenously formed Brassica napus oil is provided that is particularly well suited for use in frying application. Such oil exhibits further stability in view of the low concentration of linolenic acid that concomitantly is produced within the seeds.

Title: A method and apparatus that determines charged particle beam shape codes
Inventor: HOFMANN ULRICH
IPC: G03F7/20
Filed: 2000-01-04
Abstract: A lithography method and apparatus which represent a substrate surface as gray level values and determine a shape data that specifies a shape and position of a flash field. The apparatus receives a pattern in a vector format, represents the substrate surface as a grid of pixels, and then represents each pixel as a gray level value specifying a proportion of the pixel that includes the pattern. Subsequently the apparatus constructs a matrix of a quadrant of four pixels and surrounding pixels, modifies the matrix so that three intermediate shapes corresponding to an exposed region of the quadrant may be provided, determines an intermediate shape data of the quadrant; and performs a reverse modification on the shape to determine the shape data that specifies a flash field.
Patent CA-2324087-A1 (CA)
Inventor: STOFFELS RICHARD B
IPC: B60K26/04
Filed: 2000-10-23
Abstract: A power unit and control assembly for a motorized utility implement is disclosed, the power unit and its control assembly being attachable to a frame having wheels, at least one of which is attached to a drive axle powered by an engine. In a preferred form, the power unit includes the engine, a centrifugal clutch driven by the engine, and a transmission shaft extending from the clutch. The transmission shaft is linked to the drive axle and also engages a brake assembly for stopping the motorized utility implement. The power unit further includes a handle control assembly for controlling both the throttle of the engine and the brake assembly. The handle control assembly includes a speed control handle that simultaneously disengages and engages the brake assembly and variably opens and closes the throttle, thereby permitting greater or lesser forward speeds. The handle control assembly also preferably includes a brake control lever attached to a stationary portion of the handle control assembly, whereby the brake assembly may be disengaged without opening the throttle of the engine, thereby permitting manual, rather than powered, movement of the motorized utility implement. Preferably, actuation of the brake control lever disables the speed control handle, to prevent inadvertent engagement of the throttle while the brake assembly is disengaged.

Title: Digital video decoding of compressed digital pictures by correcting corrupted header information with an estimated picture size
Inventor: MIYAZAKI TAKASHI
IPC: H04N19/136
Filed: 2000-11-24
Abstract: A video decoding apparatus receives a compressed digital video signal containing a sequence header and at least one coded picture. A coded sequence data contained in the header is decoded and stored in a memory.      A video decoding process is performed on the coded picture. During this process a first macroblock count is produced to represent the number of macroblocks contained in the decoded picture and the decoding process is suspended. A second macroblock count is then determined from picture size data in the memory and compared with the first macroblock count. The video decoding process by using the stored sequence data is resumed immediately after the first and second macroblock counts are determined to be equal to each other. Otherwise, this decoding process is delayed until the sequence data of the memory is corrected with data representing an estimated picture size.
