Filed: 2000-12-13
Abstract: PROBLEM TO BE SOLVED: To complete analysis and evaluation of total performance of electric system within a short period of time with a method of analyzing the performance of electric system including a motor and a control by utilizing an analysis model. SOLUTION: The number of flux linkages of motor is analyzed in regard to a discrete rotating angle and a discrete current value in which the rotating angle and current are respectively discretized with an adequate step under an FEM model as an analysis model. The discretization of the discrete rotating angle is conducted, when an absolute value of the differential value for the rotating angle in the number of flux linkages is large, in the step which is smaller than that when such absolute value is small. Accordingly, discretization of a plurality of discrete current values can be conducted, when the absolute value of the differential value for a current in the number of flux linkages is large, in the step which is smaller than that when the absolute value is small.  Therefore, according to this method, a degree depending on the FEM model to calculate the number of flux linkages can be lowered than that of the prior art. As a result, the time required for analysis, evaluation and design of the electric system can be reduced easily.

Inventor: MICHAEL G CRONIN
IPC: F16H47/04
Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a transmission assembly having a hydrostatic pressure driving type transmission with a variable displacement hydraulic device controlling a motor speed ratio. SOLUTION: This transmission assembly comprises a mechanical transmission connected to a hydrostatic pressure driving transmission and having a first range and a second range and an output shaft driven under a running speed ratio. When the mechanical transmission is shifted from the first range to the second range, torque caused by the hydrostatic pressure driving transmission is reversed. A synchronous running speed ratio is a motor speed ratio producing the same running speed ratio in both the first gear range and the second gear range. An iso-displacement running speed ratio is a ratio where the displacement of a variable displacement device in the second gear range is the same as that in the first gear range. A running speed ratio difference is a difference between the synchronous speed ratio and the iso-displacement running speed ratio.  A shifting from the first range to the second range is started from the iso- displacement running speed at the running speed ratio varying in the range smaller than 80% of the running speed ratio difference.

Title: Converged ion beam column including energy filter
Inventor: WANG LI
IPC: H01J37/153
Filed: 2000-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a converged static electron particle beam device capable of raising a current density by reducing the expansion of the particle energy to decrease the chromatic aberration in the system. SOLUTION: The resolution of static electron particle beam such as a converged ion beam (FIB) or the like is optimized by inserting an energy filter into the ion beam route. The energy filter serves to pass the ion having the required energy only and to scatter and remove the ion having the other surplus energy. The chromatic aberration of the ion beam is reduced by restricting the expansion of the ion beam energy. As a result, the current density of the ion beam rises. The energy filter can be composed of, for example, a Wien filter best fitted to an energy filter but no a mass filter. To generate the expansion of the energy, for example. Another energy filter can be used, which generate an electric field combining a tetrode field and a dipole field in the magnetic field using a tetrode structure between two magnetic pole pieces.
