Patent CA-2221902-A1 (CA)
Title: Brake mechanism and powered actuator
Inventor: TAKANO TOMOHIRO
IPC: H02P3/10
Filed: 1997-11-21
Abstract: A brake mechanism includes a reduction gear train, a motor structure, and a braking means. The reduction gear train transmits at least a rotation force in a first rotational direction supplied from a drive source. The reduction gear train is imparted with a returning tendency in a second rotational direction opposite to the first rotational direction. The motor structure has an output shaft rotatably connected to the reduction gear train. The braking means has field magnets, an armature coil, a braking circuit, and either one of a fixed resistor, a variable resistor, a rectifying diode, a Zener diode, a varister, a constant-current diode, a light-emitting diode, and a lamp bulb. The braking means generates a torque in the first rotational direction to the output shaft which, upon being disconnected from the drive source, rotates to return in the second rotational direction through the reduction gear train in accordance with the returning tendency, thereby suppressing a returning rotation speed of the reduction gear train. A powered actuator is also disclosed.

Inventor: CYR NORMAND
IPC: H04B10/2569
Filed: 1998-02-23
Abstract: Apparatus for measuring very low levels of polarization mode dispersion of optical devices, that is inexpensive, robust and portable, comprises a broadband source and a polarizer for directing substantially completely polarized broadband light into the device under test with the polarization in a plane substantially perpendicular to the propagation direction of the light. Light leaving the device is analyzed spectrally to produce a spectrum of intensity in dependence upon wavelength or frequency of such light four each of at least two mutually orthogonal polarization axes in a plane perpendicular to the propagation axis of the light leaving the device. The spectra are used to compute Stokes parameters S1, S2 and ~ S3~ for each of a plurality of wavelengths within the bandwidth of the broadband light. The polarization mode dispersion of the device is characterized in dependence upon the Stokes parameters using one of several techniques including standard Fixed Analyzer techniques and polarimetric techniques, especially the Poincare sphere technique. The apparatus is particularly suitable for measuring PMD of components of optical telecommunications systems, including optical fibers, optical isolators, couplers, light amplifiers, and dispersion compensators.

Abstract: Disclosed is a recombinant viral particle capable of infecting a eukaryotic cell, the viral particle comprising: a substantially intact viral glycoprotein fused, via an intervening linker region, to a heterologous polypeptide displayed on the surface of the particle, which heterologous polypeptide modulates the ability of the viral particle to infect one or more eukaryotic cell types and is cleavable from the viral glycoprotein by a protease acting selectively on a specific protease cleavage site present in the linker region, such that cleavage of the heterologous polypeptide from the viral glycoprotein allows the glycoprotein to interact normally with its cognate receptor on the surface of a target cell.
Patent CA-2234479-A1 (CA)
Title: Novelty lamp
Inventor: KAVIANI ALI
IPC: G09F19/02
Filed: 1998-04-09
Abstract: A novelty lamp which comprises a transparent container with a top surface, a bottom surface, an outer portion, and an inner portion. The inner portion extends upwardly from the bottom surface of the container and defines a hollow area. The bottom surface of the container is mounted in a base member. Two substances are received in the container. One of the substances has a higher relative density at room temperature and is immiscible with the other substance. Upon application of heat, which is supplied by a light bulb mounted within the base member, globules of the substance with the initially higher relative density become less dense, rise in the other substance and flow around the outer and inner portions of the container. As the globules rise toward the top surface of the container they cool, become more dense and drop back down toward the bottom surface of the container.

Title: Bandsaw machine
Inventor: FUJIWARA KATSUTOSHI
IPC: B27B13/08
Filed: 1998-05-29
Abstract: A bandsaw machine comprises lower and upper wheels supported by a stationary shaft and a movable shaft, respectively, a bandsaw mounted on and around the wheels to run therearound, and a bandsaw tension mechanism for normally stretching said bandsaw. The bandsaw tension mechanism includes a lever, a weight hung from one end of the lever, a push rod having a lower end connected to the other end of the lever and an upper end engaging the movable shaft, and a vibration absorber interposed between the weight and one end of the lever. Thus, a balance weight is not directly influenced by vibration of a balance lever caused by changes in tensile force of a bandsaw, and thereby prevents transfer of its vibration to the bandsaw, changes in tensile force of the bandsaw, vibration and unstable travel of the bandsaw.

Abstract: Deux techniques de compression de bande vocale connexes sont utilisées afin de permettre l'adaptation d'un système de télécommunications HF avec des signaux de données de modems en bande vocale haute vitesse et de télécopieurs. Un codeur-décodeur haute vitesse permet au système de télécommunications de passer les transmissions par télécopie et modem en bande vocale jusqu'à 9,6 kb/s. Un codeur-décodeur ultra haute vitesse supporte des transmissions par télécopie et modem en bande vocale jusqu'à 14,4 kb/s. Le codeur-décodeur haute vitesse fonctionne au moyen de trois créneaux HF 16 périodes ou quatre créneaux HF 8 périodes, et le codeur-décodeur ultra haute vitesse fonctionne à l'aide de quatre créneaux HF 16 périodes. Du fait que ces codeurs-décodeurs transmettent des informations sur plusieurs créneaux HF pouvant être contigus, les créneaux dans les canaux de communication HF sont affectés de manière dynamique. La fonction d'affectation dynamique des créneaux temporels/largeurs de bande détecte et contrôle la transmission de données et forme un canal de données à partir du nombre nécessaire de créneaux.
