Title: Formation of oxide film
Inventor: WADA TOSHIAKI
IPC: C23C14/34
Filed: 1986-06-02
Abstract: PURPOSE:To prevent side etching when an Al2O3 or SiO2 film formed by sputtering voltage to the substrate side and continuously dropping it within a specified range with the lapse of sputtering time. CONSTITUTION:When an Al2O3 or SiO2 film is formed on a substrate by sputtering, negative bias voltage is applied to the substrate side and continuously dropped from 200V to 0V with the lapse of sputtering time. The resulting oxide film is etched. The extent of side etching proceeding between a mask and the oxide film during etching is remarkably reduced as compared with the extent of side etching between a mask and an oxide film formed by conventional sputtering.

Abstract: PURPOSE:To prevent an unmanned traveling vehicle from running away and from getting out of a guiding line by decelerating target vehicle velocity by braking it with a brake cylinder when acceleration of the vehicle velocity is considerably large at the time of traveling down on a slope in an automatic traveling state. CONSTITUTION:In the brake mechanism of the unmanned traveling vehicle, a brake cylinder 37 is expanded/contracted with the revolution of a motor corresponding to a signal from a radio transmitter or the like, and a braking arm 33 is turned to right and left at fixed speed. Then, a controller part detects whether or not the acceleration of the vehicle velocity is higher than 0.3Km/h during 250 seconds as the critical acceleration not generated on the flat ground and in the case of YES, the downward slope is judged. Next, it is judged whether or not the brake cylinder 37 is set under an ON command and when the ON state is continued for 500 seconds, the velocity is decelerated for 0.2Km/h so as to be settled down within a critical range 3.5-5.5Km/h of the target vehicle velocity.
