Patent CA-2351326-A1 (CA)
Inventor: TANAKA TETSUO
IPC: G02B6/38
Filed: 1999-11-25
Abstract: Electroforming is performed in an electroforming bath with a cathode of a metal wire member immersed in an electroforming solution to electrodeposit nickel around the aluminum alloy wire member. The aluminum alloy wire member is removed by dissolution with an alkaline solution from an obtained nickel electroformed product. Accordingly, a nickel cylinder is obtained, which has a through-hole formed corresponding to the wire member. The cylinder is cut into those having a predetermined length. The outer circumference is subjected to cutting based on the through-hole to obtain a ferrule. The inner diameter accuracy of the through-hole of the ferrule is determined by the outer diameter accuracy of the wire member. Therefore, it is unnecessary to perform polishing for the through-hole. The highly accurate ferrule is obtained in accordance with the simple process at low cost. The PC polishing for the ferrule for effecting PC junction of optical fibers is extremely easy, because the ferrule is made of metal.      Thus, it is possible to provide a high performance optical fiber connector.

Filed: 2000-10-20
Abstract: To produce meta-type aromatic polyamide filaments having a good quality from a polymer solution of a meta-type aromatic polyamide produced by a solution polymerization method, with high efficiency, (1) a meta-type aromatic polyamide is prepared by polymerization-reacting a meta-type aromatic diamine with a meta-type aromatic dicarboxylic acid chloride in a polar organic solvent; (2) hydrogen chloride contained in the resultant polymer solution is neutralized with a neutralizing agent containing an alkali metal hydroxide which can react with hydrogen chloride to produce a salt thereof insoluble in the polymerization solvent; (3) the salt deposited from the polymer solution is removed by filtration; (4) the resultant polymer solution is mixed with water and a polar organic amide solvent to prepare a spinning solution; (5) the resultant meta-type aromatic polyamide spinning solution is directly extruded in the form of filamentary streams into an aqueous coagulation liquid, to coagulate the extruded filamentary streams of the polymer solution into the form of filaments; (6) the coagulated filaments are immersed in water to remove the salt and the solvent from the filaments; and (7) the water-washed filaments are drawn and heat-treated.

Title: Method and apparatus for subsurface measurements with directional sensitivity particularly adapted for reservoir monitoring applications
Inventor: HOMAN DEAN M
IPC: G01V3/30
Filed: 2001-08-23
Abstract: Methods and apparatus for monitoring the properties of a subsurface reservoir are provided. A tubular is equipped with external transmitting and/or receiving antennas configured to provide electromagnetic measurements with directed sensitivity. The tubular includes a recess formed on the outer circumference to house an antenna and electronic components, thereby reducing the tubular radial profile. A shield apparatus is mounted to the tubular to further protect the antennas mounted thereon. A tubular equipped with one or more antennas comprising a coil array, a set of saddle coils, tilted coils, or a combination thereof, provides for selective steering of the measurement sensitivity. Slots are formed on the tubular to attenuate current flow in the tubular that may result from interaction with an antenna mounted thereon. Power and/or signal data transfer between the antennas and the surface is achieved via a wireline coupled between the antennas on the tubular and the surface, or by other suitable means.

Title: Battery recharging device and method and an automatic battery detection system and method therefor
Inventor: CARKNER STEVEN
IPC: H02H7/18
Filed: 2001-10-26
Abstract: A system includes a recharging device to which an electronic hand-held device powered by a battery can be connected. A controller associated with the recharging device performs a method of internal-device battery cell detection, i.e., distinguishing between NiMH/NiCd and other types of cells in the battery, before recharging the battery. A method determines the cell chemistry without any modifications to the battery and/or without any user input by performing tests on the battery. The tests include a Battery Voltage Test, an Internal Resistance Test, and a Timed Voltage Test. The testing is performed through a combination of hardware and software in the charging cradle. By performing the tests in a preferred order, detected alkaline, lithium, rechargeable alkaline, and carbon-zinc cells, damaged NiMH and NiCd cells, and close to fully charged NiMH and NiCd cells cause termination of a recharging operation before damage to the device or battery is sustained, without requiring input from a user.

Abstract: A filter is disclosed that actively controls one or more filter characteristics, such as the cut-off frequency of a selected filter pole, while minimizing the value of selected filter components such as the capacitor components. This helps improve the performance, reliability and yield of the filter. The filter rejects a selected frequency component or frequency band by actively providing an offset signal that effectively cancels the rejected frequency component or frequency band, while allowing the remaining frequency components or frequency bands to pass relatively freely to the output of the filter. The offset signal may also be used to actively reject a DC offset voltage or current from the input signal.
