Publication number: 20090008542Abstract: In a chromatograph mass spectrometer capable of defining an appropriate measurement time range and selectively performing a scan measurement, selected ion monitoring (SIM) measurement or simultaneous scan/SIM measurement in that time range, a total ion chromatogram 51 obtained by a scan measurement of a standard sample and a previously-created compound table 52 are displayed on the screen of a display unit in the process of setting parameters in a measurement condition table. An operator selects a compound that should undergo the simultaneous scan/SIM measurement, then places a checkmark in an appropriate check box in the compound table 52, and finally clicks the “Auto-Create” button 54. Then, a measurement time range for the selected compound is defined by adding a time span before and after the retention time of that compound, respectively, and a measurement condition table 53 is automatically created and displayed on the screen.Type: ApplicationFiled: March 7, 2006Publication date: January 8, 2009Inventor: Takashi Sumiyoshi

Patent number: 7333488Abstract: A routing/switching processing unit rewrites the inbound multicast address or the source address and the destination multicast address of the inbound flow identifier of a received packet and forwards the received packet to only output ports corresponding to a resulting outbound multicast address or flow identifier. A conversion table stores first multicast addresses or flow identifiers designated by transmission sources, second multicast addresses or flow identifiers to be used for forwarding to users data transmitted from the transmission sources, and signal port IDs of signal ports to which the users are connected. A multicast packet processing unit converts the first multicast address or flow identifier of a received multicast packet to a second multicast packet or flow identifier by referring to the conversion table, and forwards the address-converted packet to network interfaces having signal ports corresponding to the second multicast packet or flow identifier.Type: GrantFiled: January 14, 2005Date of Patent: February 19, 2008Assignee: Hitachi, Ltd.Inventor: Takashi Sumiyoshi

Publication number: 20070223731Abstract: Conventional independent component analysis has had a problem that performance deteriorates when the number of sound sources exceeds the number of microphones. Conventional l1 norm minimization method assumes that noises other than sound sources do not exist, and is problematic in that performance deteriorates in environments in which noises other than voices such as echoes and reverberations exist. The present invention considers the power of a noise component as a cost function in addition to an l1 norm used as a cost function when the l1 norm minimization method separates sounds. In the l1 norm minimization method, a cost function is defined on the assumption that voice has no relation to a time direction. However, in the present invention, a cost function is defined on the assumption that voice has a relation to a time direction, and because of its construction, a solution having a relation to a time direction is easily selected.Type: ApplicationFiled: January 31, 2007Publication date: September 27, 2007Inventors: Masahito Togami, Akio Amano, Takashi Sumiyoshi

Publication number: 20070177604Abstract: The invention reduces the initial setting cost, the management cost, and reconfiguration cost of QoS guarantee for network devices. A management device has a control unit and the storage unit. The control unit obtains the number of terminals contained in the network system and connection relations of the network system at the time of initial setting for QoS guarantee. A control unit stores an operation policy which an administrator inputs. The control unit creates QoS control configuration for each connection path between adjacent two network devices using the number of terminals in the network system, the connection relations, and the operation policy. And QoS control configuration is the information for controlling the QoS guarantee of network devices. And the control unit sets the QoS control configuration in the network devices.Type: ApplicationFiled: December 21, 2006Publication date: August 2, 2007Inventors: Yoji Ozawa, Hideki Okita, Takashi Sumiyoshi, Kenichi Sakamoto

Patent number: 5329628Abstract: A database system includes a database unit for storing a database, a managing processor and a processor. The managing processor manages the database unit and accesses the database unit in response to an inputted particular request. The processor internally generates a request in accordance with a user program, directly accesses the database unit in accordance with the generated request when the generated request is one of first predetermined requests, and outputs the generated request to the managing processor as a particular request when the generated request is one of second predetermined requests. Each of the second predetermined requests incurs a change in contents of the database, and the managing processor updates a log stored in a log unit in accordance with processing for the particular request.Type: GrantFiled: January 23, 1991Date of Patent: July 12, 1994Assignee: Hitachi, Ltd.Inventors: Shoji Yamamoto, Takashi Sumiyoshi
