  • Patent number: 11314752
    Abstract: A computer system includes a first computer and a second computer. The second computer includes, a minimum analysis dataset in which a data item serving as an analysis target and a repetition unit are defined in advance for each analysis target and an agent. The agent receives an analysis target data fetching designation including the minimum analysis dataset, a repetition range of repeating acquisition of data, and a repetition unit. The agent generates a first process that acquires data from the first computer and a first instance that executes processing within the first process on the basis of the repetition range and the repetition unit and activate the first instance to acquire the accumulated data from the first computer. When the processing of the first instance is completed, the agent generates a second process that executes analysis processing and a second instance that executes processing within the second process.

  • Patent number: 7604037
    Abstract: Die opening-closing means includes a servo motor and a movement conversion mechanism and is disposed between a support plate and a base stand. A movable plate is mounted on the support plate that is disposed on the base stand via a linear movement guide. In a forging cycle, die opening and closing is performed by activation of the die opening-closing means and tie bar fixing means at a rear surface side of the movable plate, and clamping force is obtained using a die clamping cylinder provided in the movable plate. When it is necessary to change over exclusive dies and change over is performed by: extending tie bar removal cylinders provided in a frame behind the movable plate so as to remove tie bars from a fixed plate; and moving a movable rail of internal rails to an open position and moving the change over carriage in along the internal rails from the outside.
