  • Patent number: 9002171
    Abstract: 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.

  • Patent number: 8957166
    Abstract: A method for producing a propylene-based polymer, including polymerizing propylene or propylene and an ?-olefin except propylene in the presence of a catalyst with a horizontal polymerization reactor equipped with stirring vanes rotating around a horizontal axis therein by a continuous vapor-phase polymerization, which removes heat of polymerization by heat of vaporization of a liquefied propylene, wherein the reactor can set a plurality of area sections different in temperature in a horizontal direction inside the reactor, and satisfies at least one of i) a temperature difference, ?T1=T??T?, between an area section including an upstream end of the reactor (T?) and a downstream end (T?) thereof is 0.1 to 20° C. and ii) a temperature difference, ?T2=Tx?Tz, between an area section including a catalyst feed part (Tx) and dew point (Tz) of a mix gas in the reactor is 0 to 5° C.

  • Patent number: 8488866
    Abstract: 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.
