  • Publication number: 20180233124
    Abstract: The present disclosure relates to a noise reduction device, a noise reduction method, and a program capable of reducing noise in a more stable and effective manner. Signal processing is performed to generate a reference signal representing a waveform of noise on the basis of an estimation value indicating estimation of an acoustic characteristic in a route from each of a predetermined number of speakers to a microphone. Moreover, signal processing is performed for an error signal representing a waveform of an error measured by the microphone in accordance with an amplitude-frequency characteristic obtained from the corresponding one of the acoustic characteristics. Then, a filter coefficient with which the error signal becomes zero is calculated under adaptive algorithm with reference to the reference signal. The reference signal is filtered by using the filter coefficient to obtain a control signal. The control signal is supplied to the corresponding one of the predetermined number of output units.

  • Patent number: 9601253
    Abstract: Provided is a laminated-type inductance device capable of reducing the number of layers for sandwiching a non-magnetic body layer and enhancing direct-current superposition characteristics without intentionally providing a space. In a conductive pattern, portions of the outer circumferential section thereof adjacent to end surface electrodes are respectively recessed toward the inside of the pattern when viewed from above. In other words, line widths are narrower at the above portions. Further, non-magnetic paste is formed between the end surface electrode and the outer circumferential section of the conductive pattern at each of the portions where the line width is narrower. By applying the non-negative paste in a space between the conductive pattern and the end surface electrode, the portion where the non-magnetic paste is applied has the same function as in a case where the non-magnetic ferrite layer is inserted therein.

  • Patent number: 8810352
    Abstract: In a laminated inductor element, outer electrodes and terminal electrodes are electrically connected by via holes, internal wiring lines, and end surface electrodes. The via holes on an upper surface side are provided immediately under the outer electrodes and in a non-magnetic ferrite layer. The via holes on a lower surface side are provided immediately above the terminal electrodes and in a non-magnetic ferrite layer. Since outermost layers are defined by the non-magnetic ferrite layers, a parasitic inductance is not increased, even if the outermost layers are provided with the via holes. In this case, the internal wiring lines are not routed on a surface of the element. Therefore, there is no complication of a wiring pattern, and it is possible to prevent an increase in a mounting area of the element.

  • Publication number: 20090049107
    Abstract: When a database area multi-written or replicated in an external storage unit is separated, a database management system writes consistent data into the external storage unit. A method and system capable of controlling a timing of separating the replicated database area is provided. Furthermore, new data directory information necessary to access the replicated database is dynamically added based on the data directory information of the replication source database. A method and system capable of selecting whether to access the database which is the source of the replication or access the replicated database are provided. Thus, when the database area multi-written or replicated in an external storage unit is separated and physical replicated databases are created, it is possible to maintain consistency of the replicated databases while continuing transaction processing.

  • Publication number: 20070198924
    Abstract: In comparison to unnecessary page generation of the prior art, the page generation time according to the current invention is substantially reduced, and the generated page is efficiently accessed. Since in response to at least one of a predetermined set of update events, a page is dynamically generated in advance of a user page request and the dynamically generated page is stored, the current invention allows the efficient page access. The use of the prior art technologies such as proxy servers in combination further improves the cost of transmission of the page to the user according to the current invention.

  • Patent number: 7194678
    Abstract: In comparison to unnecessary page generation of the prior art, the page generation time according to the current invention is substantially reduced, and the generated page is efficiently accessed. Since in response to at least one of a predetermined set of update events, a page is dynamically generated in advance of a user page request and the dynamically generated page is stored, the current invention allows the efficient page access. The efficient page access is accomplished by storing the dynamically generated page as a static page at a URL identified by a page access call with an argument. Thus, the user accesses the previously generated dynamic page at a high-speed. The use of the prior art technologies such as proxy servers in combination further improves the cost of transmission of the page to the user according to the current invention.

  • Patent number: 7152067
    Abstract: A definition tool of the present invention declares columns which are concealed in external tables to a multi-database server. The multi-database server controls a decomposition and an execution of query messages such that the multi-database server does not perform an arithmetic using the concealed columns. The external database server encrypts the data of concealed columns in tables of query result tables. The multi-database server designates a range to be decrypted at the time of acquiring and integrating respective result tables. A client program acquires an integrated result table and decrypts the designated range. Since the data encrypted by the external database server is decrypted by and is referred to the client program, it becomes difficult for the multi-database server to refer to a content of the concealed columns.

  • Patent number: 6925462
    Abstract: The present invention relates to an optimization method in a database management system having the function of accessing external databases. Conventionally, whether functions contained in a query can be executed in external databases depends on a database management system having the functions, and therefore there has been a problem in that a database utilization method cannot apply to query optimization and query execution performance is reduced. To solve the above problem, a database management system having the function of accessing external databases is provided with an optimization step comprising the steps of: obtaining specification about whether to execute functions in a query in external databases; determining whether data referred to in a query is confined to one database; and determining whether a user specifies that the functions in the query are executed in external databases.
