Patent number: 8318357Abstract: Disclosed is a secondary battery with a non-aqueous electrolyte that has excellent cycle characteristics and output characteristics. Also disclosed is a positive electrode active material for a secondary battery with a non-aqueous electrolyte that includes a powder of a volume resistivity of 20 ?·cm or more and 100 ?·cm or less when said powder has a bulk density of 3 g/cm3. The use of the lithium nickel composite oxide as a positive electrode active material can provide a secondary battery with a non-aqueous electrolyte that has excellent cycle characteristics and output characteristics.Type: GrantFiled: May 13, 2009Date of Patent: November 27, 2012Assignee: Panasonic CorporationInventors: Junichi Sugaya, Tetsuo Nanno, Hiroshi Yoshizawa

Patent number: 7340950Abstract: To provide a flowmeter capable of enhancing metering resolution to thus effect accurate metering. When a fluid to be measured is supplied to or discharged from a metering chamber 4, a membrane 11 provided in the metering chamber 4 is reciprocally actuated, and a rotation section R1 performs rotational movement in association with reciprocal movement of the membrane 11. At this time, since the rotation section R1 is provided with a magnet 5 or a direction sensor 6, the magnet 5 or the direction sensor 6 also effects rotational movement. The direction sensor 6 detects rotational movement, to thus determine a relative position between the membrane and the rotation section. Thus, the position of the membrane 11 can be detected, and metering resolution is enhanced. Thus, accurate metering can be performed.Type: GrantFiled: September 29, 2005Date of Patent: March 11, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yasuo Koba, Hirozumi Nakamura, Takuhisa Ootani, Kazunori Ueyama

Patent number: 7313955Abstract: A liquid flow meter is disclosed including a compartment enclosure formed from an upper case part and a lower case part, the lower case part containing a volumetric measuring container having a specified fluid volume capacity, mounted upon a rotatable pivot having an axis of rotation and having a counterbalance weight. The axis of rotation of the volumetric measuring container being determined by location of said rotatable pivot. The moment created by the counterbalance weight about the axis of rotation maintains the static filling rotational position until the specified volume capacity is achieved. An influent port is formed in the upper case part for directing liquid flow approximately vertically into the approximate center of said volumetric measuring container. The lower case part has a sloped bottom and flumage to receive flow discharge of the volumetric measuring container and directs the liquid volume to an effluent port.Type: GrantFiled: January 25, 2007Date of Patent: January 1, 2008Assignee: City Meter, Inc.Inventors: Kirk N. Nivens, Jr., Kirk Nathan Nivens

Patent number: 5325725Abstract: A device for monitoring the leakage of cooling gas into the stator water cooling system is disclosed. The vent from the water cooling reservoir tank is connected to the inlet of a U-shaped passageway and the outlet of the passageway is connected to an atmospheric vent. A liquid is provided in the passageway so as to prevent the passage of cooling gas from the inlet to the outlet without a desired pressure differential. At the specified pressure differential however, gas bubbles from one side of the passageway to the other and is trapped by a measuring cup in one position. When a sufficient quantity of gas is passed under the cup, the buoyancy of the cup becomes positive allowing it to rise to a second position where at least a portion of the gas is discharged. Because the amount of gas discharged can be determined and a number of cycles of operation of the cup can be measured, the flowrate can be precisely measured.Type: GrantFiled: July 29, 1993Date of Patent: July 5, 1994Assignee: General Electric CompanyInventors: Harold C. Sanderson, Donald R. Albright

Patent number: 5253535Abstract: A method and apparatus for transporting solid particulate material and calculating mass flow rate of the material through a rotary feeder having helical pockets is provided. At least one radiation source and two or more detectors are positioned in a manner whereby radiation flux is directed through, and attenuated by particulate material contained in a helical pocket. The amount of attenuation is measured at least when the pocket is filled with material and when the pocket has discharged most of the material. The difference in the amount of flux detected at the filled and discharged positions is used to determine the mass flow rate of the particulate material.Type: GrantFiled: December 3, 1991Date of Patent: October 19, 1993Assignee: E. I. Du Pont de Nemours and CompanyInventor: William J. McCown

Patent number: 4520677Abstract: Method and apparatus for indicating mass flow of a solid particulate material through a rotary feeder. A radiation source and detector are positioned in a manner whereby radiation flux is directed through, and attenuated by, particulate material contained in rotating pockets. A Cesium-137 gamma source can be mounted within the shaft of the feeder, and one or more detectors can be mounted outside of the feeder housing. The detected signal is indicative of the mass of particulate material contained within a given pocket rotating within the feeder.Type: GrantFiled: October 30, 1981Date of Patent: June 4, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventors: Joseph E. Macko, Isnard Estriplet

Patent number: 4046208Abstract: A drum rotatable about an axis through its center of gravity carries troughs located in a circle concentric to said axis and which are charged at a certain level with flowing material to be measured as to quantity, whereby the drum is influenced by a driving moment from the weight of the charged material. After a certain rotation of the drum, the troughs discharge the charged material at a lower level than said charging level. Means are provided for counteracting rotation of the drum by said driving moment, said means including interconnected scoops arranged in a circle concentric to an axis through the common center of gravity of the scoops, said last axis forming an angle with a vertical line. The drum rotates the scoops around said last-mentioned axis, and the scoops successively elevate a second material from a certain level and discharge it at a higher level.Type: GrantFiled: December 1, 1975Date of Patent: September 6, 1977Assignee: Alfa-Laval ABInventor: Lennart Arvid Stenstrom
