Title: Systeme et procede de repetition intempestive d'appels telephoniques
Inventor: LEONARDO PANELLI
IPC: H04M7/00
Filed: 2003-08-08
Abstract: L'invention concerne un procédé  transparent de répétition intempestive d'appels, selon lequel un appel téléphonique entre un destinateur et un destinataire peut être routé comme un appel à deux bras par le biais d'un troisième point. Un contrôleur d'appels permet de capturer la composition entrée du destinataire par l'abonné au niveau du téléphone d'origine et de la communiquer à un fournisseur de services de répétition intempestive d'appels via un réseau de données séparé. Ce fournisseur de services compose et connecte deux bras de l'appel téléphonique, un bras allant des locaux du fournisseur au destinateur et un autre allant du fournisseur au destinataire. Ces deux bras sont connectés au moyen de l'équipement et des locaux du fournisseur de services, ce qui permet d'obtenir une connexion entre le destinateur et le destinataire. Ce système fonctionne de manière transparente aux yeux de l'abonné sans présenter les retards ou les inconvénients des procédés de répétition intempestive connus jusqu'ici.

IPC: H01L21/324
Filed: 1990-04-25
Abstract: Procedure and Apparatus for Rapid Thermal Annealing of Implanted Semiconductors Abstract This invention is directed to the fabrication of semiconductor devices, especially those comprising III-V and II-VI compound semiconductor materials, and involves Rapid Thermal Annealing (RTA) of semiconductor wafers, especially those implanted with a dopant(s). The invention is also concerned with a black-box implement used in combination with the RTA. The process includes enclosing a wafer to be annealed within a "black-box" comprising components of a black body material and subjecting the black box with the wafer therein to an RTA. In a preferred embodiment the RTA comprises (a) a pre-anneal step which includes heating to a temperature and for a period sufficient to preheat the wafer so as to reduce thermal shock due to a main annealing step, (b) the main annealing step being at a temperature and for a period sufficient to remove damage caused to said surface by the dopant implantation and to activate implanted dopant, and (c) a post-anneal step carried out at a temperature and for a period sufficient to relieve stresses which may result from the main-annealing step. The combined use of the RTA and the black box leads to wafers substantially free of slip lines and with reproducibly high mobilities and uniform activation. (FIG. 1)

Title: Dropout-free center point fill method for displaying characters
Inventor: PAXTON WILLIAM H
IPC: G06T11/20
Filed: 1990-07-03
Abstract: ABSTRACT         An improved method is provided for displaying characters with improved legibility at relatively low resolution by modifying the center point fill method and displaying additional pixels as needed to maintain connectivity and avoid dropout problems.  Additional pixels are turned on as needed where a black section of the character crosses the midline between two adjacent horizontal or vertical pixel centers.  If the intersection of a black section of a character with a midline is entirely within one pixel which is not otherwise turned on then that pixel is turned on; if a black section of a character crosses between two such adjacent pixel reference points in parts of both pixels and if neither pixel is already on, the pixel having more of the black section, measured along the line between pixel centers (or other reference points), is turned on.

Title: Rapid heating, uniform, highly efficient griddle
Inventor: DICKENS DAVID
IPC: H05B6/12
Filed: 1990-12-13
Abstract: A basically commercial fast heat highly efficient griddle or other heated surface has interchangeable griddle plates including magnetically permeable materials having Curie temperatures which may be the same or different to provide different cooking temperatures, the plates being heated by induction coils providing sufficient energy to heat the plates to their effective Curie temperatures in the presence of loads and of a design to maintain a uniform cooking temperature across the griddle plate to within less than an inch of the edges of the plates. The plates may be placed in an enhanced idle condition at cooking temperature by placing a cover over the plates or region of a plate not in use.      Increased efficiency is further due to an insulator blanket placed between the griddle plates and coils.

Title: Battery cable connector
Inventor: WIESLER RUDOLPH
IPC: H01M2/30
Filed: 1991-02-08
Abstract: ABSTRACT OF THE DISCLOSURE    A cable connection assembly which includes a screw or bolt member threadably receiving a nut member prior to insertion through the aperture of the battery cable and into the threaded aperture of the battery terminal.  The nut member is withdrawn to a point adjacent the head of the bolt member.  The bolt member is then passed through the cable aperture and hand tightened into the terminal aperture.  Thereafter,  in one embodiment, a first tool engages the bolt head and a second tool engages the nut,  whereupon the nut is tightened against the washer cable end.  In the process, the torsional force on the battery terminal is substantially eliminated, with the tightening of the nut, while maintaining the position of the bolt, placing a slight axial force on the terminal during connection.  For disconnection, both tools are attached to the respective parts, and the nut is loosened while the bolt is maintained in position, resulting in no torsional force on the terminal. Alternatively, either or both of the nut member and bolt head may include wing members for enabling manual operation.
