Abstract:
In an authentication apparatus, coordinates input from a coordinate detector via a plurality of discontinuous holes or openings, cutouts or marks provided on a member which is used to specify the coordinates are detected, and an authentication is made based on a comparison result of the detected coordinates and a plurality of registered coordinates.
Abstract:
A vehicle steering control apparatus includes an actuator to vary a steering gear ratio of a vehicle wheel steer angle of a steerable wheel to a steering wheel angle. A controller controls the actuator to produce an actuator torque in a steering direction at a start of a driver's steering operation.
Abstract:
The present invention provides a process of producing an activated carbon for an electric double layer capacitor, which can produce easily and inexpensively an activated carbon free from fusing of carbon particles during activation and having a small diameter, a uniform particle diameter, and a relatively large specific surface area on a commercial scale. The process comprises the steps of calcining an easily graphitizable carbon material so that the reduction rates of the hydrogen/carbon atomic ratio (H/C) and the volatile components in the carbon material are 4 percent or more and 5 percent or more, respectively after calcination and activating the carbon material thereby producing an activated carbon for an electric double layer capacitor, having an average particle diameter of 0.5 to 7 μm and a BET specific surface area of 1500 to 3000 m2/g.

Abstract:
Before the execution of simulation, variation rates at the grid points of functions for the calculation of intersections between grid points and the surface of the shape to be analyzed of a simulation model are calculated; new grid spacings are calculated by performing calculation so that the greater the variation rate the narrower the grid spacing; and where, with respect to these grid spacings, aspect ratios far deviate from 1, finite difference grids are automatically optimized by adjusting the grid spacings so that the aspect ratios approach 1. Furthermore, during the execution of simulation, the variation rates of functions, whose values are physical quantities at different grid points, are calculated, and finite difference grids are automatically optimized by performing calculation so that the greater the the variation rate the narrower the grid spacing.
