Publication number: 20150242134Abstract: An example of the invention is a computer system managing actual storage areas provided by physical storage apparatuses as a single storage pool and allocating an actual storage area to a virtual volume from the storage pool when writing data to the virtual volume from the host computers. A management computer identifies, based on access path management information, access paths for access from the host computers to the virtual volume and usage status of the access paths for access to the virtual volume, and determines, based on the usage status of the access paths, target capacity ratios of actual storage areas allocated to the virtual volume from the physical storage apparatuses providing actual storage areas to the storage pool. The physical storage apparatuses allocate actual storage areas to the virtual volume based on an actual storage area capacity already allocated to the virtual volume and the target capacity ratios.Type: ApplicationFiled: October 22, 2012Publication date: August 27, 2015Inventors: Yusuke Takada, Takuya Okamoto, Takato Kusama

Publication number: 20140085469Abstract: Calibration method of cameras is performed by using images generated by imaging a peripheral area of a vehicle by the cameras, wherein the peripheral area of a vehicle includes a calibration index pre-set on a road surface where the vehicle is positioned. The cameras are mounted on the vehicle, and the calibration index includes intersections formed by at least two first parallel straight lines and two second parallel straight lines having different inclination from the two first parallel straight lines. The camera calibration method includes steps of generating a bird's-eye-view video by viewpoint-converting each of the images based on a first camera parameter that is stored in advance; recognizing the intersections from the generated bird's-eye-view video; and calculating a second camera parameter, via which a non-deviated bird's-eye-view video can be generated, based on the recognized intersections and information on positions and poses of the cameras.Type: ApplicationFiled: August 29, 2013Publication date: March 27, 2014Applicant: Clarion Co., Ltd.Inventors: Morihiko SAKANO, Keiji SATO, Yusuke TAKADA, Tsukasa OKADA

Publication number: 20130166570Abstract: An object of the present invention is to appropriately select a volume or the like to be allocated to a host computer, thereby decreasing work efficiency. Upon being inputted with a precondition (for example, a user ID, a host ID and a work label ID) based on information inputted from a user, a management server 10 identifies a search condition set corresponding to the precondition and recommends this search condition set to the user. The user can utilize the recommended search condition as-is, or after changing a portion thereof. The management server instructs a storage system to allocate the retrieved volume or the like to the host.Type: ApplicationFiled: September 8, 2010Publication date: June 27, 2013Applicant: HITACHI, LTD.Inventors: Yusuke Takada, Yoichiro Tsuge, Tetsuya Maita, Toshiyuki Haruma

Patent number: 7352342Abstract: It is an object of the present invention to provide a plasma display apparatus in which reliable erase discharge is performed and an erroneous discharge is suppressed, even when a discharge sustain period is shortened so as to realize a PDP having high definition. The above object is achieved in the following manner. In the discharge sustain period, a pulse applied in the later part of the discharge sustain period has a larger pulse width than a pulse applied in the earlier part of the discharge period, except for an initial pulse in the discharge sustain period. In addition, a called narrow pulse is applied in an erase period to perform an erase discharge. According to this method, wall voltages in discharge cells at the end of the discharge sustain period are raised to a higher level than in the related art. As a result, reliable erase discharge is performed, and an erroneous discharge is suppressed.Type: GrantFiled: January 31, 2007Date of Patent: April 1, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuaki Nagao, Yusuke Takada, Toru Ando, Masaki Nishimura

Patent number: 7176851Abstract: When applying sustain pulses to each discharge cell in a gas discharge panel, a pulse of the opposite polarity is briefly applied immediately before the leading edge of each sustain pulse. Or, the absolute voltage of each sustain pulse is set higher during a certain period from the leading edge of the sustain pulse than during a period from the lapse of the certain period to the trailing edge of the sustain pulse, and a pulse of the opposite polarity is briefly applied immediately after the trailing edge of the sustain pulse. As a result, discharge delays during a discharge sustain period are suppressed to improve image quality, and reactive currents are reduced to improve luminous efficiency.Type: GrantFiled: March 13, 2001Date of Patent: February 13, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akira Shiokawa, Ryuichi Murai, Yusuke Takada
