Patent number: 11347813Abstract: A system and computer implemented method for cataloging database metadata using a signature matching process are provided. The method includes receiving an input name to be matched to a key in a seed table; generating a first fingerprint by decomposing the received input name into a first set n-grams; generating, based on the received input name, a second fingerprint using a predetermined pronunciation schema, wherein the second fingerprint is a phonetic fingerprint; generating a third fingerprint by decomposing the second fingerprint into a second set of n-grams; identifying a matching key by matching any combination of the first fingerprint, the second fingerprint, and the third fingerprint against keys in the seed table; and cataloging the metadata with the matching key as a tag.Type: GrantFiled: December 26, 2018Date of Patent: May 31, 2022Assignee: HITACHI VANTARA LLCInventors: Tomoya Wada, Winnie Cheng, Rohit Mahajan, Alex Mylnikov

Patent number: 9724702Abstract: A particle diameter of a raw material to be pulverized can be decreased within a short time period. A vibration mill includes a container having therein a columnar space with a central axis of the columnar space being almost horizontal while the container is held so as to be vibratable in a direction of within a plane that is almost perpendicular to the central axis, a cylindrical medium disposed in the container so as to be vibratable, and a plurality of pulverizing media disposed inside the cylindrical medium so as to be vibratable. The ratio of an inner diameter of the cylindrical medium in contact with the pulverizing medium to an outer diameter of the pulverizing medium is 2.1 or more. The integrated value of volumes of the pulverizing media relative to a space volume inside the cylindrical medium in contact with the pulverizing medium is more than 25%.Type: GrantFiled: July 12, 2012Date of Patent: August 8, 2017Assignee: KAO CORPORATIONInventors: Takafumi Uematsu, Tomoya Wada, Kazutomo Osaki, Naoki Nojiri

Patent number: 9339784Abstract: Provided are methods and apparatus for forming electrode active materials for electrochemical cells. These materials include a metal (e.g., iron, cobalt), lithium, and fluorine and are produced using plasma synthesis or, more specifically, non-equilibrium plasma synthesis. A metal containing material, organometallic lithium containing material, and fluorine-containing material are provided into a flow reactor, mixed, and exposed to the electrical energy generating plasma. The plasma generation enhances reaction between the provided materials and forms nanoparticles of the electrode active materials. The nanoparticles may have a mean size of 1-30 nanometers and may have a core-shell structure. The core may be formed by metal, while the shell may include lithium fluoride. A carbon shell may be disposed over the lithium fluoride shell. The nanoparticles are collected and may be used to form an electrochemical cell.Type: GrantFiled: December 15, 2014Date of Patent: May 17, 2016Assignee: QuantumScape CorporationInventors: Yiguang Ju, Tomoya Wada, Nan Yao, Wenting Sun, Jingning Shan
