Patent CA-2219731-A1 (CA)
Inventor: TANABE RUMI
IPC: H04L25/06
Filed: 1997-10-30
Abstract: When the received symbol is located within one of regions G, H, I, L, M, N, Q, R, and S, 2 bits are decided to be most reliable to obtain their soft decision values = 0 or 7. As for the remaining 2 bits, a soft decision value = 0 to 7 is decided by soft decision in the I- or Q-axis direction. When the received symbol is located within one of regions A, E, U, and Y, all the 4 bits are decided to obtain their soft decision values = 0 or 7. When the received symbol is located with one of regions B, C, D, F, J, K, O, P, T, V, W, and X, 3 bits are decided to be most reliable to obtain their soft decision values = 0 or 7. As for the remaining 1 bit, a soft decision value = 0 to 7 is obtained by soft decision in the I- or Q-axis direction. A soft decision method that can implement soft decision in multilevel (amplitude and/or phase) modulation and can fully exhibit the correction performance of maximum likelihood coding can be provided.

Title: Stereo enhancement system
Inventor: KLAYMAN ARNOLD I
IPC: H04S1/00
Filed: 1996-04-26
Abstract: A stereo enhancement system processes the difference signal component generated from a pair of left and right input signals to create broadened stereo image reproduced through a pair of speakers or through a surround sound system. Processing of the difference signal component occurs through equalization characterized by amplification of the low and high range of auditory frequencies. The processed difference signal is combined with a sum signal, generated from the left and right input signals, and the original left and right input signals to create enhanced left and right output signals.

Patent CA-2226069-A1 (CA)
Title: Visually-readable reagent test strip
Inventor: KISER ERNEST
IPC: G01N33/558
Filed: 1997-12-30
Abstract: A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for the color-change reaction. The inhibitor concentration increases in successive assayareas; thus, the number of areas that change color is a measure of the analyte concentration. The test strip is particularly adapted for measuring glucose in awhole blood sample. In a preferred embodiment, the sample is guided to the assay areas along a path formed by crushing selected areas of a membrane, and the assay areas are uncrushed areas of the membrane.

Title: Volumetric pump with bi-directional sphincter seal
Inventor: DAVIS CLARK C
IPC: F04B53/02
Filed: 1998-01-22
Abstract: A volumetric pump comprises a housing having an elongate cavity with open and closed ends. A resilient sheet of material having two branched portions forming an aperture is disposed over the housing. A pump shaft is slidably disposed through the aperture such that one branched portion toward the cavity and the other branched portion extends away from the housing such that a sphincter seal is formed about the shaft. An inlet conduit leading from a fluid source passes through the housing into the cavity near one end thereof, and an outlet conduit leading to a fluid sink passes through the housing from the cavity near the other end thereof. The shaft is driven back and forth in reciprocating motion, to alternatively produce a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.

Title: Seal plate for a gas turbine moving blade
Inventor: FUKUNO HIROKI
IPC: F01D5/22
Filed: 1998-03-11
Abstract: The present invention relates to a seal plate at the platform portion of a gas turbine moving blade.  The seal plate is inserted in a gap between the adjacent platforms at each end portion of a seal pin to prevent air from leaking to the outside.  A groove is provided at each of four corners of the end portion of platform of the moving blade, and the seal plate is inserted to cover the gap so as to extend the end portions of the adjacent platforms, by which the gap between the platforms is blocked.  A seal pin and end seal pins are inserted between the platforms to seal this portion.          However, there is a gap at the end portions, so that cooling air leaks from the lower part of platform.  Since the seal plate is inserted in the groove to block the gap, the sealing property is increased.

This  construction  makes  it  possible  to reduce  the  patient's  pain  and  such  a  troublesomeness  as frequent  drug administration and continuously administer a necessary drug over a prolonged period of time while taking a contraceptive measures.
Patent CA-2234234-A1 (CA)
Inventor: MIMURA KENJI
IPC: F16C29/00
Filed: 1996-03-01
Abstract: An object of the present invention is to realize a device of simple construction for generating at all times a steady and appropriate friction resistance even if the speed changes relative to the rotational or linear movement of an object and also easily controlling the magnitude of frictional force by changing loads. In other words, when a rotational body (1) is caused to rotate in a state in which a load is axially applied thereto, each roller (2) rolls while in contact with the rotational body (1) and a receiving body (3). Since each roller (2) is forced to move along the rotational track of the rotational body (1) by being prevented by a cage (4) from rolling in a direction inclined at a predetermined angle relative to the rotational track of the rotational body (1), a friction force in proportion to an axial load is generated between each roller (2) and the rotational body (1) and the receiving body (3). At that time, since each roller (2) slips while rolling, combined sliding friction and rolling friction are generated, whereby a steady resistance can be obtained.

Patent CA-2235946-A1 (CA)
Inventor: BENEST ROGER SIDNEY
IPC: A01C23/04
Filed: 1996-10-31
Abstract: A method and apparatus for droplet generation in agricultural or other spraying comprises supplying air and liquid to a supply chamber (28, 102) having an outlet orifice (38, 114), and entraining the liquid in the air flow for droplet formation. Air and liquid are injected into the supply chamber which has a closed end wall (42, 108) on which the liquid forms a continuous film which moves outwards towards the orifice for droplet formation thereat. The supply of air and liquid to a chamber wall (42, 108) or target from which the liquid proceeds with direction change to an entrainment outlet at suitable pressures causes droplets formed to have a droplet size particularly suitable for effective coating of plant material and the momentum provided to the droplets by the air enables controlled direction of the resulting spray mist even at very low liquid volumes per hectare.

IPC: B29C43/42
Filed: 1998-05-08
Abstract: A method and apparatus for compression molding plastic articles such as closures include a plurality of tools mounted in opposed pairs with the tools of each pair including opposed male and female mold sections. The tool pairs are mounted for motion in an endless path. The tool pairs and associated mold sections are closed during motion in the path for compression a molding charge in the mold cavity formed between the mold sections of each pair and opened to release an article formed between the mold sections. A latch mechanism is associated with each pair of tools for holding the tools and mold sections in the closed position during motion in the path independent of the mechanism for closing the tools and mold halves. In this way, forces imparted to the mold halves and tools to hold the mold closed are isolated from the machine frame. The latch mechanism is selectively unlatched to permit opening of the mold halves and release of the article compression-molded between the mold halves.
