Title: Dispositif a semi-conducteur de silicium-germanium et son procede de fabrication

Abstract: Un dispositif à semi-conducteur doté d'une diode tunnel (23), convenant particulièrement à diverses applications. Ledit dispositif comprend deux régions à semi-conducteur (2, 3) adjacentes, présentant un type de conductivité opposé et ayant des niveaux de dopage si élevés qu'un claquage entre eux conduit à une conduction par effet tunnel. Le dispositif connu présente un inconvénient en ce que la caractéristique de courant-tension n'est pas encore assez raide pour certaines applications. Dans le dispositif de l'invention, les parties (2A, 3A) des régions de semi-conducteur (2, 3) adjacentes à la jonction (23) comprennent un cristal mixte de silicium et de germanium. On a découvert avec étonnement que le niveau de dopage du phosphore et du bore sont sensiblement augmentés, à condition que la même quantité d'impuretés que celle utilisée lors de la formation du reste des régions (2, 3) soit fournie. En conséquence, l'efficacité de l'effet tunnel est sensiblement améliorée, également en raison de la bande interdite réduite desdites régions (2A, 3A), et le dispositif de l'invention présente une caractéristique courant-tension beaucoup plus raide à la fois dans le sens direct et dans le sens inverse. Cela permet d'envisager, entre autres, une application avantageuse dans laquelle la jonction PN (23) à effet tunnel est utilisée comme une zone de transition entre deux diodes classiques, telles que des diodes PN ou PIN, qui sont utilisées en superposition et qui peuvent être formées dans un procédé de croissance épitaxiale selon l'invention. Les parties (2A, 3A) adjacentes à la jonction (22) à effet tunnel présentent de préférence une épaisseur de 5 à 30 nm et comprennent entre 10 et 50 at % de germanium. Le niveau de dopage peut être de 6 x 1019 voire même de plus 10?20 at/cm3¿. L'invention porte encore sur un procédé simple de fabrication d'un dispositif de l'invention, de préférence à une température comprise entre 550 °C et 800 °C.

Abstract: An interactive display apparatus comprises an audio subsystem (4), a control subsystem (5) and a plurality of video subsystems (2, 3). The video subsystems (2, 3) have access locally to image data, including image files and live video. The video subsystems (2, 3) are controlled by the control subsystem (5) which then sends command messages to the video subsystems (2, 3). A person watching the display (22, 42) of one of the video subsystems (2, 3) can dial into the audio subsystem (4) and thereby control the operation of the video subsystem (2, 3). To do this, the audio subsystem (4) notifies the control subsystem (5) of incoming audio command signals. It is to be noted that when the system is on line, the control subsystem (5) does not transfer image data to the video subsystem (2, 3) but merely sends commands setting the format of the images displayed on the screens (22, 42). <IMAGE>

Abstract: A method of preparing a porous film comprises electrodepositing material from a mixture onto a substrate, the mixture comprising: (I) a source of metal, inorganic oxide, non-oxide semiconductor/conductor or organic polymer, (II) a solvent such as water; and (III) a structure-directing agent such as octaethylene glycol monododecyl ether in an amount sufficient to form an homogeneous lyotropic liquid crystalline phase in the mixture. Electrodepositing the film from a lyotropic liquid phase in this manner provides a porous film having a substantially regular structure and substantially uniform pore size. Following deposition, the porous film may be treated to remove the structure-directing agent. The porous film may optionally be subjected to further treatment such as the electrochemical or chemical insertion of ionic species, the physical absorption of organic, inorganic or organometallic species, or the electrodeposition, solution phase deposition or gas phase deposition of organic, inorganic or organometallic species.

Abstract: A radar test system for testing a collision avoidance radar system. The radar test system includes circuitry to downconvert a signal from the collision avoidance radar to an intermediate frequency signal, to delay the intermediate frequency signal to simulate the delay of a return signal from an object located a particular distance from the collision avoidance radar system, and to upconvert and transmit the intermediate frequency signal back to the collision avoidance radar system to determine if the collision avoidance radar system provides accurate distance readings. The radar test system further couples the intermediate frequency signal to a spectrum analyzer. The spectrum analyzer can be used to determine if the collision avoidance radar system is operating within the 76-77 GHz frequency band allocated by the Federal Communications Commission (FCC). The radar test system further couples the intermediate frequency signal to a power meter. The power meter can be utilized to determine the power of the signal transmitted from the collision avoidance radar system.

Formatting instructions are transmitted from the computer to the reader that correspond to the type of the card. A command is sent for authenticating the personal code and the authentication command is verified in the reader. For a qualified authentication command, the reader is put into a secure mode which blocks anyone with fraudulent intentions from intervening in the procedure to obtain the personal code. The personal code is then inputted via the keypad of the reader, formatted for the particular type of card used, and the formatted code and the command for authenticating it are transmitted from the reader to the integrated circuit of the card. The card compares the formatted code with a pre-stored personal code.

Abstract: The present invention relates to (with reference to FIG. 1), apparatus (10) for playing a game. The apparatus (10) has a payment acceptor (30,31) for receiving payment of a stake from a player of the game. The apparatus (10) has a plurality of randomisers (60, 70) each of which can generate a random combination of indicia from a set of available indicia. The apparatus (10) has a plurality of selectors (52, 53) operable by a player for selecting one or more of the plurality of randomisers (60, 70) to be played in a turn of play. The apparatus (10) has activating means (54) for activating the randomisers (60, 70) and comparator means for determining a winning combination of indicia. The apparatus (10) has payment means (90) for awarding a winning payment to a winning player of the game. The activating means (54) in every turn of play activates all of the randomisers (60, 70) and in every turn of play each randomiser generates a random combination of indicia. Each of the randomisers (60, 70) comprises a set of rotatable mechanical reels. The randomisers (60, 70) operate independently of each other such that the chances of one randomiser (60, 70) generating a particular set of indicia are completely unaffected by the indicia generated by any other randomiser. Each of the plurality of selectors (52, 53) is associated with only one of the plurality of randomisers (60, 70) and is used by a player to select only the associated randomiser (60, 70) for play in a turn of play. The comparator means determines a winning combination of indicia by both separately for each set of reels (60, 70) checking whether the generated indicia comprises a winning combination and by checking which set or sets of reels (60, 70) have been selected for play. The comparator means determines a win only when a selected set of reels (60, 70) displays a winning combination of indicia.
