  • Publication number: 20030120577
    Abstract: A computer is used to perform the calculations for obtaining a capital composition corresponding to a predetermined default probability based on a probability distribution of a return on investment, a weighted average cost of capital based on the capital composition, a borrowing cost, and an equity cost, and a market efficiency value added from the weighted average cost of capital and a net operating profit after tax. The market efficiency value added obtained through these calculations is then displayed appropriately so as to provide support in decision-making.

  • Patent number: 5078008
    Abstract: An apparatus for controlling output shaft torque of an engine in an engine tester by correction inertia of the dynamometer, comprising an operation pattern generator, a dynamometer processing unit, a dynamometer controller, and a dynamometer. The torque signal fed back to the dynamometer controller is not from the shaft torque meter but is of the dynamometer torque, and is not affected by the torsional vibration, and is controlled with good stability. Further, no time lag caused by the inertia of the dynaomometer develops in controlling the torque of the output shaft. Therefore, the torque of the output shaft can be controlled with high response and accuracy.
