Title: Sistema anticaída de un avión, con alerón posterior para tobera
Inventor: PORRAS VILA F JAVIER
IPC: B64C15/02
Filed: 2012-06-22
Granted: 2014-10-28
Abstract: El sistema anticaída de un avión, con alerón posterior para tobera, es un mecanismo de defensa contra una eventual caída. El sistema se sitúa en la popa, detrás de una Tobera (3) que recorre al avión de principio a fin, estrechándose en la zona posterior, esto hará que la fuerza del aire que lo recorra cuando el piloto abra la puerta anterior de dicha tobera (3), -en el caso de que el avión caiga en picado-, dicha fuerza, se multiplicará en ese estrechamiento, y, saldrá con mucha fuerza para impactar contra un alerón (6) móvil y posterior que añadimos frente a la salida del tubo (3). Esto permitirá que el avión remonte altura muy rápidamente, evitando así el posible impacto contra el suelo, y, no sólo eso, sino que además, el avión podrá mantenerse en vuelo todo el tiempo que le haga falta, aún sin motor.

Abstract: The transistor relates to a bipolar integrated circuit field effect transistor, esp. suitable for integrated circuits.  A thin insulator is used so that the current can flow by not thermal electron emission from semi-insulating layer but tunneling.  And there is an overlap range to induce an inversion layer.  The transistor is made by the steps of : making a window by source diffusion after growing an oxide on n-type epitaxial layer grown on n+-type wafer; growing field oxide to remove boron glass after diffusing boron; and forming turnneling oxide and simultaneously coating Al on the rear of wafer and source window.
