The evaluating method includes: dipping a mirror-polished silicon wafer in a dilute hydrofluoric acid; washing the surface of the silicon wafer; subjecting the surface-washed silicon wafer to a heat treatment in an oxygen atmosphere to form a thermal oxidation film; forming a predetermined number of polycrystalline silicon electrodes having a predetermined area on the thermal oxidation film; applying a voltage to each electrode between the predetermined number of polycrystalline silicon electrod...

An SAT estimator 16 estimates the SAT generated between the road surface and the tire. A slip angle arithmetic unit 18 estimates the front wheel slip angle. A lateral force detector 180 computes the lateral force generated in the wheels. An SAT model value arithmetic unit 22 computes the SAT model value from the slip angle estimate and the lateral force value. A front-rear direction quantity-of-state arithmetic unit 240 computes the front-rear direction quantity of state generated in the wheels....

An SAT estimating section estimates self-aligning torque (SAT) on the basis of a steering torque, which is detected by a steering torque detecting section, and an assist torque, which is detected by an assist torque detecting section. An SAT model value computing section computes an SAT model value by using an integrated slip angle .alpha..sub.I. An SAT ratio/drift amount computing section computes, by on-line identification, a ratio (SAT ratio) of the SAT to the SAT model value, and a drift amo...

A MOS capacitor in which an insulating layer of thermal oxide film is disposed between the electrode 2 and the silicon wafer 1 is formed. While a light beam of an energy larger than 1.1 eV is irradiated on the electrode 2 and its periphery, electrons inject from the electrode 2 side (voltage is applied from the silicon wafer 1 side). The injected electrons are activated by the light irradiation. For both p-type or n-type semiconductor, the dielectric breakdown electric field strength can be prec...

Tire air pressure during high speed travel is estimated without a sensor for detecting the tire air pressure directly. An apparatus is constituted by a wheel speed sensor, road surface friction state estimator for estimating a friction state estimation value representing friction between the tire and a road surface from wheel speed detected by the wheel speed sensor, tire air pressure estimator for estimating any reduction in the tire air pressure based on the friction state estimation value, an...

To reduce the power dissipation of a static random access memory, a write enable signal is applied to the gates of load MOS transistors on bit lines which are connected to a memory cell. During the write-in time, the load MOS transistors are turned off so as to prevent as electric current from flowing from a power source into the earth through the memory cell.
