IPC: H01L29/12
Filed: 2000-10-02
Abstract: L'invention concerne un procédé permettant de former de manière contrôlée des nanostructures en silicium, tel qu'un réseau de fils quantiques en silicium. Une surface de silicium est vaporisée par un flux uniforme d'ions moléculaires d'azote sous vide extrêmement élevé, de façon à former un relief périodique du type vague, dans lequel les creux sont au même niveau que le bord de l'isolant en silicium de la matière SOI (isolant sur silicium). L'énergie ionique, l'angle d'incidence des ions à la surface de ladite matière, la température de la couche de silicium, la profondeur du relief de type vague, la hauteur dudit relief et la plage de pénétration des ions dans le silicium sont tous déterminés sur la base d'une longueur d'onde sélectionnée du relief comprise entre 9 nm et 120 nm. Un masque de nitrure de silicium comportant des bords suspendus est utilisé afin de déterminer la superficie de la surface de silicium sur laquelle le réseau est formé. Les impuretés sont éliminées de la surface de silicium dans la fenêtre du masque avant la vaporisation. Afin de former un réseau de fils quantiques en silicium, l'épaisseur de la couche de silicium SOI est sélectionnée de façon à être supérieure à la somme de la profondeur, de la hauteur et de la plage de pénétration des ions, la fabrication des fils de silicium étant commandée par une valeur seuil d'un signal d'émission ionique secondaire provenant de l'isolant SOI. La nanostructure peut être utilisée dans des dispositifs optoélectroniques et nanoélectroniques, tels qu'un transistor TEC.

Abstract: The invention relates to a mounting device for fastening a silencer to the barrel of a portable firearm. The mounting base (7) of a silencer is provided with a part (7) that can be twisted around the axis of the bore with respect to the barrel (9) and a stationary part (6). The aim of the invention is to provide a mounting device with which the effects of the silencer on the shot placement consistency of the pertaining arm can be compensated. To this end, the silencer is twisted from shot to shot when the arm is tested. In the position of twist that is found to be optimal, the part (7) that can be twisted and the stationary part (6) are firmly interlinked so that the angle of rotation of the silencer with respect to the barrel (9) is always the same every time the silencer is mounted on the arm.

Patent CA-2405417-A1 (CA)
Inventor: ZHANG ZHIYI
IPC: G01V3/28
Filed: 2001-04-05
Abstract: A Neural Network (NN) is used for borehole correction (205) of resistivity logging data (201). The method comprises two stages. In the first stage (Fig.  3), the entire range of possibilities of earth models relevant to borehole compensation is sampled and a suite of tool responses (105, 107) is generated, with and without the borehole. A wide range tools responses including the borehole effects are input to the NN and the NN is trained (113) to produce the corresponding borehole-free response. In the second stage (Fig.4), the NN  is validated by using as input tool responses (including borehole effects) that were not used in the training of the NN and comparing the output of the NN to the corresponding borehole-free response. If the agreement is good, then the NN has been validated and may be used to process subsequently acquired data that includes borehole effects.

Abstract: A colored music notation system and a method of colorizing music notation using seven colors that are easily distinguishable from one another, representing the seven unique notes in an octave. The color of a note may be chosen from a list of colors in CMYK format, with a tolerance of plus or minus ten points, preferably plus or minus five points in attributes for any of the colors. The colors may be reproduced by any printing method, including using a conventional personal computer. The colors are easily reproducible within acceptable tolerances on a wide variety of media and with a range of printing options, can be read under various lighting conditions, and do not make written music unpleasant to the eye. The colors are also sufficiently different to allow for easy recognition of common chord combinations by the recollection of simple groups of colors. In the preferred embodiment of the invention, notes affected by an accidental are the same color as the natural note to which they are related. The invention also provides a method for applying color to the keys a keyboard instrument.
