Patent CA-2259580-A1 (CA)
Inventor: BUECHLER CHRISTIAN
IPC: G11B7/09
Filed: 1997-06-23
Abstract: The present invention relates to a device for reading from or writing to optical recording media, which uses the "Differential Phase Detection Method" for tracking. This method has deficiencies if optical recording media (4) having different pit depths are to be used. The object of the present invention is to propose a device of this type which can also be used with the said optical recording media (4). This object is achieved by virtue of the fact that delay elements (7, 8, 9, 10) are arranged between the photodetector (5) and the phase detector (14). The device according to the invention is used as a playback or recording device for optical recording media such as, for example, CD, CD-ROM, CD-I, CD-R, DVD, DVD-ROM, DVD-R, etc.

Abstract: An outboard motor includes an alternator belt-driven by an engine and equipped with a plurality of fans for taking outside air into the interior of the alternator, and a belt cover which covers an endless belt used for driving the alternator and at least an upper portion of the alternator.      The alternator is continuously driven while the engine is running. The cooling fans provided on the alternator rotate in unison with a rotor of the alternator. The outside air taken into an engine room through fresh air intake holes provided in an engine cover is drawn by the cooling fans into the interior of the belt cover through a multiplicity of air passage holes formed in the belt cover, so that the alternator is cooled by the outside air drawn into the belt cover.

Title: Systeme de detection pour tuyaux d'aeration manquants sur une embouteilleuse
Inventor: HANAN RICHARD R
IPC: B67C3/22
Filed: 1997-07-11
Abstract: Système de détection pour tuyaux d'aération métalliques manquants (28) sur une embouteilleuse (10), avec buse (52) d'alimentation en flux (56) de liquide conducteur frappant le tube manquant. Une vanne électromagnétique (62) régit l'arrivée du liquide dans la buse et est activée par un signal de commande du régisseur de l'embouteilleuse. Le système comporte en outre un générateur (66) qui produit un signal avec signature destinée à être appliquée à la buse. Une entrée du circuit détecteur est reliée au châssis de l'embouteilleuse pour déceler la présence du signal à signature dans le châssis, suite à la conduction depuis le tuyau d'aération. Le détecteur répond à l'absence de signal avec signatures à l'entrée en fournissant un signal de sortie qui équivaut à un tuyau d'aération manquant. Le régisseur réagit à ce signal en interrompant l'embouteilleuse jusqu'à l'action corrective appropriée.

Title: Drugs for ameliorating ocular circulatory disorders
Inventor: WATANABE NORIKO
IPC: A61K31/551
Filed: 1997-10-23
Abstract: Drugs for ameliorating ocular circulatory disorders characterized by containing as the active ingredient 1,4-dihydropyridine derivatives represented by general formula (I) or acid-addition salts thereof, wherein each symbol is as defined in the specification. When dropped into the eyes, in particular, the above drugs enhance the blood flow in optic papillae and inhibit retinal vasoconstriction, a decrease in the blood flow in optic papillae and attenuation of VEP amplitude in the eyes with circulatory disorders caused by ET-1 without elevating the ocular tension. These facts suggest that the above drugs are useful as remedies for glaucoma, in particular with normal ocular tension, caused by ocular circulatory disorders, retinal pigment degeneration, macular degeneration, ischemic optic neuritis, iridocyclitis, retinal arterial obliteration, retinal phlebemphraxis, diabetic retinitis, choroid diseases following retinal lesions, retinal/choroid diseases associated to systemic diseases, etc.

Abstract: Cette invention concerne un procédé et un appareil permettant d'obtenir un système de répartition dans un système de radiotéléphones cellulaires. L'appartenance à un groupe de répartition peut être créée de manière implicite en attribuant un numéro de téléphone commun à tous les membres dudit groupe de répartition, et/ou de manière explicite en associant les stations mobiles à un ou plusieurs groupes de répartition dans une base de données centralisée du réseau de téléphones cellulaires. Lorsqu'un appel téléphonique est placé par un répartiteur ou des stations mobiles appartenant au groupe de répartition, le réseau de téléphones cellulaires va contacter chaque membre du groupe de répartition de manière à créer un appel de conférence en duplex intégral entre tous les membres dudit groupe de répartition. Dans un mode de réalisation de cette invention, les appels téléphoniques vers les stations mobiles passent en mode de conférence au niveau de la passerelle du réseau de téléphones cellulaires. Dans un autre mode de réalisation, les appels téléphoniques vers les stations mobiles passent en mode de conférence de manière hiérarchique.

Filed: 1999-07-16
Abstract: This invention relates to processes for the production of symmetrical polyurea-urethane coated granular fertilizer products, and to the symmetrical polyurea-urethane coated granular fertilizer products produced by these processes. These processes comprise coating fertilizer granules with compounds which react to form urethane coatings which contain terminal isocyanate groups, followed by polymerization of these urethanes to form symmetrical polyurea-urethanes. Suitable compounds comprise a) an organic polyisocyanate component, and b) an alkanol-amine component containing at least one tertiary amine group and at least one hydroxyl group. These compounds are present in sufficient quantities that the molar ratio of isocyanate groups to isocyanate-reactive groups is from about 1.6:1.0 up to about 10.0:1.0 in each encapsulating layer. It is necessary that sufficient amounts of these compounds are applied to the fertilizer granules such that the symmetrical polyurea-urethane coated granular fertilizer particles contain from about 0.5 to about 15% by weight of polyurea-urethane, based on the total weight of the encapsulated fertilizer particles.
