Patent number: 6827479Abstract: A uniform small particle homogenizer for liquid product comprising a pair of intensifier cylinder pumps (20) driven by a hydraulic system (22). The pumps have a power stroke side and a suction stroke side, and a pair of proximity sensors (24) that interface with each pump to detect forward and rearward movement. A microprocessor (26) with timing capabilities controls the sequential operation of each pump with the power stroke of each pump timed to alternately produce a flow of the liquid product with a precisely timed flow overlap period from the alternating pumps. Since the power stroke takes a longer time than the suction stroke, the instant each power stroke is started the opposite pump is timed to hesitate and slightly overlap until a constant product flow-rate is produced from the alternating pumps, which eliminates large variances in pressure and therefore achieves uniformity in product particle size.Type: GrantFiled: September 30, 2002Date of Patent: December 7, 2004Assignee: Amphastar Pharmaceuticals Inc.Inventors: Frank Zhishi Xia, Mary Ziping Luo, Jack Yongfeng Zhang

Patent number: 6827496Abstract: A four-point ball bearing includes: an inner ring and an outer ring defining raceway grooves, respectively. Each of the raceway grooves is constituted by two circular arcs different in curvature provided on opposite sides of a widthwise center of the raceway groove. A plurality of balls are arranged between the inner and outer rings so that the balls can roll. In at least one of the raceway grooves, a center of curvature of one of the circular arcs and a center of curvature of the other circular arc are displaced from each other at least in a radial direction so that spin is generated in each of the balls.Type: GrantFiled: August 27, 2002Date of Patent: December 7, 2004Assignee: Koyo Seiko Co., Ltd.Inventors: Takashi Iwata, Yoshitaka Nakagawa

Patent number: 6827499Abstract: To provide a method of manufacturing a two-dimensional optical connector component by stacking a plural number of one-dimensional optical connector components using at least four parallel disposed guide pins. The positions of the guide pins are determined by at least five pieces of beams. According to this method of manufacturing a two-dimensional optical connector component, optical connector components, such as an FA, can be stacked with high precision. There is also provided a guide pin jig usable for the above-mentioned manufacturing method. The jig is provided with at least four pieces of parallel disposed guide pins, and at least five pieces of beams for determining the position of the guide pins.Type: GrantFiled: July 8, 2002Date of Patent: December 7, 2004Assignee: NGK Insulators, Ltd.Inventors: Akira Matsumoto, Masashi Fukuyama, Akiyoshi Ide

Patent number: 6827500Abstract: A precise fiber array is formed using a chuck to tightly hold as an array with hexagonal packing a group of precision ferrules into ones of which is inserted and bonded a fiber end. The bonding is typically performed by gluing the fiber into the ferrule. The ferrules may also be bonded to each other. Once the ferrules are bonded together, the chuck may be removed. The terminating end of the fibers may be polished. Alternatively, cleaved terminating fiber ends may be employed, with the various terminating ends being coordinated, e.g., by an optical flat. The ferrules may have a tip and a conical entrance. The chuck may hold the ferrules in a straight orientation. The fiber terminating faces of all of the ferrules may be substantially coplanar. The ferrules may be arranged in a hexagonal configuration.Type: GrantFiled: June 29, 2001Date of Patent: December 7, 2004Assignee: Lucent Technologies Inc.Inventors: Nagesh R Basavanhally, Cristian A Bolle, Paul Robert Kolodner, Rene R Ruel, John David Weld

Patent number: 6827501Abstract: To provide a fabricating method of an optical communication part in which an optical element is fixed within a hollow holder, including the step of fixing an optical element by holding the optical element in a hollow portion of a holding portion of a metal made holder and calking a portion of the holder; wherein, the step includes calking the holder by heating the holder to a temperature higher than a operating temperature or cooling the holder to a temperature lower than the operating temperature depending on whether or not a thermal expansion coefficient of the holder is larger or smaller than that of the optical element. When the thermal expansion coefficient of the holder is larger than that of the optical element, and a heating temperature in calking is set within the range of 85° C. to 95° C., while when the thermal expansion coefficient of the holder is larger than that of the optical element the cooling temperature of the holder upon the calking is set within the range of −50° C.Type: GrantFiled: February 26, 2003Date of Patent: December 7, 2004Assignee: Kyocera CorporationInventors: Toshimichi Yasuda, Toshihiro Takimoto, Takayoshi Morooka

Patent number: 6827502Abstract: The present invention provides a two VCSEL array mounted in a single can with a monitoring diode. One VCSEL is directed toward the can window (for coupling with an attached fiber optic in a completed subassembly) and the other is directed toward the monitor diode. The two VCSELS are electrically coupled in parallel, are connected to the same pins in the TO can, and are driven by the same source. Preferably the two VCSELS are identical or nearly identical. The current of the monitor diode is proportional to the light emitted by both VCSELs. Since the monitor diode measures incident light from the second VCSEL, no angle of reflection is affected by changes in temperature. Since the two VCSELs are coupled in parallel, the device has a naturally low impedance.Type: GrantFiled: March 6, 2001Date of Patent: December 7, 2004Assignee: Infineon Technologies AGInventor: Stefan J. Burmeister
