Abstract:
A workflow executing method to execute a workflow of a plurality of steps according to a workflow definition. The method includes obtaining setting information of a user instructing execution of the workflow, which is setting information related to the execution of the workflow. The method also includes modifying the workflow definition corresponding to the workflow of which the user instructed execution, based on the obtained setting information. The method continues by dividing the workflow definition modified with the modifying unit for each workflow executing apparatus that executes the workflow definition. The method also includes executing at least one of the divided workflow definitions and sending at least one divided workflow definition to another workflow executing apparatus that executes processing based on the workflow definition, whereby workflow definitions are modified to match user settings, and the modified workflow definitions are divided to match apparatuses executing the workflow definition.
Abstract:
A workflow execution device is provided. The latest update date information relating to date when update is performed is added to each step of a workflow definition file. When executing each step of the workflow definition file, processing execution date information relating to date when the execution is performed is added to data processed. Subsequently, when executing each step of the workflow definition file, the final processing date of the data is determined from the processing execution date information added to the data processed. In a case where the update date determined from the latest update date information prior to the execution is later than the final processing date of the data to be processed in the execution, the processing in the execution is cancelled.

Abstract:
A dc power supply circuit connects a plurality of dc circuit breakers to a semi-conductor converter, returning again to the semi-conductor converter through a dc driving part such as an electric railcar connected to each dc circuit breaker. A second dc circuit breaker of larger capacity than the above-mentioned dc circuit breakers is provided in a return circuit and opened when a short circuit current is detected. A current decreasing means opens the second dc circuit breaker to decrease the short circuit current and includes, for example, a series-circuit of a resistor R and a reactor L. The dc power supply circuit has a large interruption capacity with low resistance loss.
Abstract:
A commutation type DC breaker having a commutation circuit electrically connected in parallel to a main contact. The main contact is connected between a DC power supply and a load. The commutation circuit is a series circuit of a commutation capacitor, a reactor and a commutation switch, with an energy absorption device electrically connected in parallel to the main contact. A switch or a breaker for preventing the flow of commutation current from the commutation circuit to the load in a non-load opening mode is connected between an electrical connection point (P), of the main contact and the commutation circuit, and the load and is opened substantially simultaneously with the opening of the main contact, or before the closure of the commutation switch. In this manner, the safety on the load in the non-load opening mode is enhanced.
Abstract:
A converter pressure control device for use in a converter waste gas disposing device wherein a calculator determines the difference between the pressure in a converter and atmospheric pressure and sets an operating parameter according to the detected difference. A pressure controller generates a control signal in accordance with the operating parameter and the difference in converter pressure and a predetermined value. The control signal is used to operate a damper to control the flow of waste gas through the converter.
Abstract:
A method for operating a converter on the basis of a direct observation of the slag-forming conditions in a vessel interior.A device for observing the vessel-interior light is disposed in a throughhole extending through the side wall of a top-blowing or top- and bottom-blowing converter to reach the vessel interior. The converter operation can be carried out at a high accuracy of the slag-amount control on the basis of this observation.
