Patent EP-0152961-A2 (EP)
Inventor: TAGUCHI YOSHINORI
IPC: G06F3/033
Filed: 1985-02-22
Abstract: Disclosed is a position detecting apparatus which has a position detecting section (10, 20) having elongated magnetic bodies (11 a-11 e, 21a-21e) and a plurality of exciting lines (12a-12i, 22a-22i) and a plurality of detecting lines (13a-13h, 23a-23h) which are arranged altematingly such as to cross the magnetic bodies orthogonally thereto. A driving power source (30) is adapted to apply A.C. voltage of a predetermined frequency to the exciting lines. A position appointing magnetism generator (50) applies a local magnetic bias to the magnetic bodies. The position appointed by the position appointing magnetism generator is detected through the detection of the voltages induced in the detecting lines. According to this arrangement, the position appointing magnetism generator can be handled easily because it is not connected to any stationary part of the apparatus, and the position can be detected at a high precision without being affected by external induction and noises and without producing noise which would affect nearby devices.

Abstract: The insulating and stability characteristics of silicon dioxide gate oxide insulator for field effect transistors are enhanced by subjecting the silicon dioxide to an annealing in an ambient that contains a gaseous oxygen-containing species in an amount sufficient to provide a partial pressure from the oxygen-containing material of about 1.33 × 10⁻⁹ bar to about 1.33 × 10⁻² bar during annealing temperatures of about 500°C to about 1200°C. Such is carried out for a time sufficient to enhance the insulating and stability characteristics of the silicon dioxide insulator.
