Patent CA-2318667-A1 (CA)
Inventor: ROLSTON DAVID R
IPC: H01L31/18
Filed: 2000-09-11
Abstract: A monolithic semiconductor photo-coupler device comprises a substrate made of semiconductor material, and a groove made in one face of the substrate to receive and align an optical fiber. A wall of given thickness is formed in the semiconductor material of the substrate in the prolongation of the groove and transversally to this groove. The wall has, on the side of the groove, a first face generally perpendicular to the groove, and a second face opposite to the first face. The semiconductor material preferably comprises silicon whereby p-doped and n-doped regions can be produced on the first and second faces of the wall, respectively. These p- and n-doped regions are separated by an intrinsic semiconductor region. Finally, first and second electrodes are applied to the substrate in contact with the p- and n-doped regions. The p-doped region, the intrinsic semiconductor region and the n-doped region form a p-i-n photodetector capable of converting an optical signal from an optical fiber placed in the groove to an electric signal. When placed in the groove, the optical fiber is in direct alignment with the photodetector. The present invention is also concerned with a method for fabricating the above described monolithic semiconductor photo-coupler device.

Abstract: The joint reinforcement member (30) for a hollow structure of an automobile vehicle (13) has a carrier portion (22) with an outer surface. The carrier portion has a base portion (30) with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis.  The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer (38) is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality of extensions extending from a base portion that correspond to the hollow structure, applying a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive is bonded to the structural member.

Inventor: DANTU RAMANAMURTHY
IPC: H04Q3/00
Filed: 2000-09-13
Abstract: A system and method for transporting IN/AIN signaling (e.g., SS7 signaling) over an IP-based network using Stream Control Transmission Protocol (SCTP), wherein a peer-to-peer protocol adaptation (PPA) structure is provided at a signaling node. The PPA structure includes an interworking functionality between an MTP3 layer and the SCTP messaging, and operates to provide a symmetrical MTP2 adaptation interface therebetween. The PPA interface functionality facilitates the implementation of network management capabilities included in the MTP3 layer such that the advantageous features of SS7 signaling are retained in the SCTP transport. The MTP2 adaptation interface functionality is processed locally with respect to the signaling node, rather than backhauling the associated signaling to an external node via an IP connection. The PPA structure may be provided at any signaling node operable to establish a virtual link across an IP connection such as, for example, a signaling gateway, an IP-compliant SCP or STP, et cetera.

Title: Slider for a slide fastener
Inventor: YAMAGISHI KOJI
IPC: A44B19/30
Filed: 2000-10-26
Abstract: The present invention intends to provide a zipper pull of a slider for slide fastener formed of resilient body on which no unreasonable force is applied when the fastener is opened or closed and which is always kept in a stabilized condition that it is urged to be fallen onto a slider body without swinging freely. A yoke which is a zipper pull mounting portion is mounted on a top face of a slider body. A half-annular shaped zipper pull formed of resilient body is fixed to lateral bars at front and rear ends of a rectangular connecting body longer than the slide body. A lateral bar is provided in the center of the connecting body and inserted through an automatic locking pawl lever incorporated in the yoke. Neck portions are provided in the vicinity of a fixing portion at the front and rear ends so that the zipper pull is elastically deformable easily. A grip portion is provided at a position apart from the fixing portion so that the zipper pull is easy to grip.      Further, a feature of the zipper pull of this invention is that a central portion to be disposed on the slider body of the connecting body is low while the sides of the fixing portions on both ends are located higher and extended horizontally with a step. Consequently, when the zipper pull is brought up slightly, the locking pawl lever can be raised so that the slider can be slid. The zipper pull is always kept in such a stabilized condition that it is fallen to the slider body.

Abstract: The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.

IPC: B01J8/04
Filed: 2001-04-09
Abstract: Combustion of the light hydrocarbon takes place in a zone comprising porous material during which the combustion gases restore their enthalpy to the porous medium and leave the reactor at the adiabatic temperature. Production of a gaseous mixture containing hydrogen and carbon monoxide, by the partial oxidation of a light hydrocarbon by an oxygenated medium, the process operating autothermically. The heat released by the oxidation is recovered to maintain the endothermic reaction produced between the non-oxidized hydrocarbon fraction and CO2 and water vapour. The gaseous reaction mixture is passed through a porous pre-heated zone enabling heating by thermal exchange to a temperature threshold sufficient to initiate the combustion reactions ; application of external heat is thus superfluous when functioning permanently.

Title: Method and apparatus for stimulating heavy oil production
Inventor: NENNIGER EMIL
IPC: E21B43/34
Filed: 2001-06-21
Abstract: This invention relates to a process for the recovery of hydrocarbons from a hydrocarbon bearing formation having an extraction chamber where the extraction chamber has an extraction surface. The process has the steps of heating a solvent, such as propane, and then placing the solvent into the extraction chamber at a temperature and a pressure sufficient for the solvent to be in a vapour state in said chamber and to condense on said extraction surface. The next step is to produce a liquid blend of solvent and heavy oil and then to separate the solvent from said heavy oil. Then the solvent is purified, before being re-injected into the formation again. The purification step removes less condensable fractions from the solvent to ensure a purity that is high enough to support continued heat transfer at extraction conditions. The pressure and temperature are set to levels to cause less volatile fractions to drain away with the liquid bitumen and solvent blend that is produced, thus mitigating heat transfer poisoning.
