Patent number: 9002171Abstract: According to one embodiment, there is provided a control block including a read control processor for reading designated content, a time information processor for processing time information. A controller returns, to a user terminal, a response signal, and information indicating a second absolute time point when an operation is executed in response to a request signal generated by the user terminal at a first absolute time point. The controller stores time difference information indicating a time difference between the first and the second absolute time points. When responding to a further request signal sent from the requester via the network, the controller sets, as tag time information, time information obtained by correcting, using the time difference information, a current relative time period for which the designated content is read.Type: GrantFiled: December 3, 2012Date of Patent: April 7, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Hideo Kataoka, Hajime Aoyama

Patent number: 8488866Abstract: A inspection image data of the chip A is captured and the data representing the amount of correction of flare corresponded to the chip A is appropriately loaded from the map storage block. Next, a inspection image of the chip A? is captured, and the data representing the amount of correction of flare corresponded to the chip A? is loaded from the flare map storage block as the amount of shifting of the edge of the contour of the pattern. The amount of correction is converted, by a correction data generation block which is a correction data generator, into the amount of geometrical correction of pattern which provides correction data. In the comparison block, the images of the geometry of two chips are compared and corrected on the amount of correction of flare generated by a correction data generation block, to thereby judge whether defect is found or not.Type: GrantFiled: February 18, 2010Date of Patent: July 16, 2013Assignees: Renesas Electronics Corporation, Fujitsu Semiconductor LimitedInventors: Tsuneo Terasawa, Toshihiko Tanaka, Hiroyuki Shigemura, Hajime Aoyama, Osamu Suga
