Patent number: 10325674Abstract: According to the present invention, a phylogenetic tree can be created on the basis of frequency data regarding a large number of mutations detected from the samples of a cancer. Each sample to be analyzed contains a mixture of plural clones having different genomes. Mutations having about the same frequencies are grouped to make plural groups, and an analysis is executed based on data listing the mutation frequencies of individual groups (called mutation group frequency data). It is assumed that pairs of clones corresponding respectively to mutation groups such that frequencies of one group is equal to or greater than that of another in all the samples have parent-child relations, and a graph structure having the clones as vertices and the parent-child relations as edges is created.Type: GrantFiled: March 17, 2016Date of Patent: June 18, 2019Assignee: Hitachi, Ltd.Inventor: Tomohiro Yasuda

Patent number: 9416892Abstract: An electromagnetic valve includes a pressing member fixed farther towards an electromagnetic movable section side than a valve chamber in a nozzle. The pressing member is fixed to a plunger farther towards the side where the plunger is pressed by the pressing member than a position where the pressing member is fixed to the nozzle. Thus, a magnetic circuit defined by magnetic flux that is generated from a magnet is prevented from being located at a portion not related to an attractive force between a core and the plunger such that it is possible to effectively utilize the magnetic flux as an attractive force between the core and the plunger.Type: GrantFiled: October 20, 2014Date of Patent: August 16, 2016Assignee: NIDEC TOSOK CORPORATIONInventors: Fumio Kai, Tomohiro Yasuda

Patent number: 8321485Abstract: To achieve high speed document search, an inverted index is compressed at high compressibility by an encoding method decodable in a high process speed. In compressing an identification number of a document to obtain a byte sequence by the variable byte method, w bits are used to represent the number of occurrences of the indexing term in the document, and x bits are used to represent additional information of the posting, where x and w are integers given as parameters. When the number of occurrences cannot be represented within w bits, a certain value indicating a numeric value that cannot be represented by w bits is stored is written to the said w bits, and anther byte sequence that represents the value by the variable byte method follows. Additionally provided is a means for reading a compressed posting from any position of a list of postings called inverted lists, allowing a binary search on an inverted list.Type: GrantFiled: November 7, 2007Date of Patent: November 27, 2012Assignee: Hitachi, Ltd.Inventors: Tomohiro Yasuda, Makoto Iwayama, Osamu Imaichi

Patent number: 7966307Abstract: A document search apparatus capable of an index-type search and a scan-type search performs a search in a combination of the two search types while compensating for the disadvantages of the two search types with each other. A search query for index-type search and a search query for scan-type search are constructed based on a search query consisting of a logical formula of keywords. Then, a character 2-gram for performing an index search is set to shorten the whole search time, and the index-type search is performed. Finally, a scan-type search is performed on this search result of the index-type search.Type: GrantFiled: June 5, 2008Date of Patent: June 21, 2011Assignee: Hitachi, Ltd.Inventors: Makoto Iwayama, Kazutomo Ushijima, Osamu Imaichi, Tomohiro Yasuda
