| 20110041503 | Turbine Protection Device - An object of the present invention is to provide a turbine protection device which can interrupt backflow from a deaerator to a turbine completely even if a check valve provided between the deaerator and the turbine can not interrupt the steam flow between the deaerator and the turbine completely. In order to achieve the above object, a control unit sends commands to a shutdown valve device so as to close the shutdown valve device when a differential pressure resulted from subtracting a pressure of a extraction steam from a pressure within the deaerator becomes greater than or equal to a first predetermined value. As a result, the backflow from the deaerator to the turbine is interrupted by a stop valve of the shutdown valve device. | 02-24-2011 |

| 20080251500 | CONTROLLER FOR WIRE-CUT ELECTRICAL DISCHARGE MACHINES - In a reference (n-th) machining pass, the wire travels along a machining route RTn and passes through a reentrant angular corner with wire position WMn, producing a workpiece edge Hn. In the following (n+1)-th machining pass, the wire travels along a machining route RTn+1, but the straight sections preceding and following the corner are replaced with a circular arc route so that the wire passes smoothly through a straight route, then a circular arc route, and then a straight route. The radius of curvature of the circular arc route is determined in the controller on the basis of the difference between the offset specified for the reference (n-th) machining pass and the offset specified for the (n+1)-th pass in which the circular arc route is inserted. Accordingly, the machining margin does not increase in the reentrant angular corner and the machining accuracy is thereby improved. | 10-16-2008 |
