Title: Method of making a glass envelope
Inventor: BECKEN KEITH J
IPC: B23K26/06
Filed: 2006-12-01
Abstract: A method of minimizing stress in an OLED device laser sealing process using an elongated laser beam. A laser beam having an intensity distribution which decreases as a function of distance from the longitudinal axis of the beam is passed through a mask to create an elongated beam having a length-wise intensity distribution which decreases as a function of distance from the axis of the beam and a substantially constant width-wise intensity distribution. The elongated beam is traversed over a line of frit disposed between two substrates. The tails of the length-wise intensity distribution provide for a slow cool down of the frit as the beam traverses the line of frit.

Title: Matcher.
Inventor: SCHILLER MICHAEL
IPC: G06K9/00
Filed: 1986-04-01
Abstract: A set of Search identification points (16) derived from an optical scan (12) of a finger are compared against File identification (18) points for the same finger. A multiple comparator (20) divides the finger image into multiple segments. The Search and File points from each segment are compared separately. A difference table (D.T.) (22) provides a proximity value Q for each search point. The D.T. is purged (28, 30) of all entries representing multiple Search points. The purge keeps those entries having the highest Q value. The purged D.T. with recalculated Q values is the basis for correcting the position of each Search point on the image plane to compensate for shift in finger position and for the variable distortion and changes that come about in a finger over time and upon successive applications of the finger to input scan (40). The corrected Search points are compared against the File points to establish a new D.T. A proximity value Q for each entry on this D.T. is calculated and a proximity value Q for the entire table is calculated. These proximity values in view of the number of entries on the difference table are used to verify identification in a scoring routine (52).

Title: Process for preparing multilayer printed circuit boards.
Inventor: RUSZCZYK STANLEY J
IPC: B05D3/10
Filed: 1987-09-10
Abstract: Multilayer printed circuit boards are fabricated by preparing a first layer in conventional manner by forming a resist image on a copper clad substrate, etching away unwanted copper, removing the resist from the circuit pattern and optionally applying a dielectric mask such as conventional solder mask to selected portions of the circuit pattern. A second layer, and optionally one or more subsequent layers, are fabricated by providing an image of a second circuit pattern in a predetermined location on said first layer, the image being formed using a suspension of cuprous oxide in a curable resin material. The image is cured at least partially and subjected to chemical reduction to convert at least a portion of the cuprous oxide to metallic copper such that the unreduced cuprous oxide in resin serves as a dielectric layer. The image is then electrolessly plated with copper to build up the circuit pattern and the latter is selectively coated with a dielectric mask before repeating the cycle to build up one or more additional layers. Solder can be applied to selected areas of any of said printed circuit layers at any appropriate time during fabrication. The above method of fabrication has advantages of economy of time, materials and labor as compared with methods hitherto employed to prepare multilayer boards in which a plurality of single boards are fabricated individually and then assembled as a sandwich or laminate by application of heat and pressure.

Filed: 1988-06-16
Abstract: Procédé consistant à remplir un support en un matériau actif avec une pâte préparée en malaxant un oxyde de plomb présentant une teneur en minium allant jusqu'à 90 % ou un mélange de cette poudre d'oxyde de plomb et d'une poudre de plomb avec de l'eau et de l'acide sulfurique en tant que composants principaux. Etant donné qu'on utilise une poudre d'oxyde de plomb présentant une teneur en minium allant jusqu'à 90 %, le minium à la surface de l'oxyde et l'oxyde de plomb dans le noyau des particules sont liés directement et la force de liaison entre les matériaux actifs lors du malaxage de la pâte est améliorée. La plaque ainsi préparée assure une meilleure adhésion de la pâte sur le support de matériau et une force de liaison importante entre les matériaux actifs. Par conséquent, le rendement du chargement de formation peut être amélioré grâce au minium et la durée de vie des accumulateurs s'en trouve prolongée.

Title: Fluxless soldering method.
Inventor: YONEYAMA TAKAO
IPC: C03C27/04
Filed: 1992-12-09
Abstract: A soldering method wherein, even when, for example, a pressure sensor unit having a sensor chip incorporating therein a highly integrated type semiconductor circuit is jointed to a metal stem, fluxless soldering can be performed without damaging the surface of the sensor chip. For this purpose, in forming a nickel layer for jointing by soldering and an oxidation preventing layer of a nickel layer on the surface of a member to be jointed, this oxidation preventing layer is formed before the soldering to a film thickness for suppressing exposure of nickel of the above-described nickel layer to the outermost surface of the member to be jointed after a thermal histeresis in association with the thermal histeresis to be received by the member to be jointed, the oxidation preventing layer is heated in a reducing atmosphere to melt a soldering foil and jointed to another member to be jointed by soldering. With this arrangement, even if the member to be jointed is subjected to the thermal histeresis before the soldering, exposure of the nickel layer, which is a base ground, to the outermost surface of the member to be jointed can be effectively suppressed, whereby substantially, there is no lowered soldering wettability on the jointed surface of the member to be jointed, even if the load imposed on the jointed portion is not increased during the jointing by soldering, satisfactory soldering wettability on the jointed surface can be realized, and, since the jointing by soldering is effected by heating in a reducing atmosphere, a fluxless soldering is possible that can provide highly tightly sealed jointed portion. Therefore, in jointing the pressure sensor unit having the sensor chip incorporating therein the highly integrated type semiconductor circuit to the metal stem, there is no need of loading the metal stem with the sensor chip facing downward, so that a disadvantage of damaging the surface of the sensor chip can be obviated.

Title: Method for improved manufacture of cement in long kilns.
Inventor: HANSEN ERIC R
IPC: F27B7/36
Filed: 1993-07-09
Abstract: The present invention is directed to a method and apparatus for controlling the kiln gas stream (90, 138) in a conventional long wet or dry process cement kiln (10). A portion of the kiln gas stream (90) can be withdrawn from the rotary kiln vessel (17) at a point upstream, relative to kiln gas flow of the chain system in the mineral drying zone (24). Alternatively, or in conjuction with bypass formation, the apparatus (256) can be used to add tertiary air to the kiln gas stream (90) to promote combustion efficiency downstream of the clinkering zone (28). Use of the present apparatus (56, 156) to form a kiln gas bypass stream (64) enhances operating efficiencies of long kilns by reducing dust loss, by facilitating isolation of high alkali by-product streams, by reducing alkali content of collected kiln dust, by increasing energy efficiency of long kiln operation, and by allowing greater overall control in the cement manufacturing process.

Title: Movable sheet for laminar flow and deicing
Inventor: SHATZ SOLOMON
IPC: B64C1/12
Filed: 1995-10-25
Abstract: A movable sheet overlying a wing is disclosed that creates laminar flow over its exposed surface. The movable sheet serves as an integral, retractable shield for protecting a suction support structure of a wing against contamination, and also serves as a movable, conductive substrate for deicing by means of electrical resistance or hot-gas heating. The invention includes a movable sheet that is mounted scroll-like on two motor-driven rollers. The sheet has a solid area without perforations that protects the suction support structure from contamination, and a porous area with perforations therethrough that allows boundary layer suction. The motor-driven rollers scroll the sheet to cover the suction support structure with either the solid area or the perforations of the sheet. Contact rollers at the edge of the sheet supply electrical current to resistively heat the sheet and melt any accumulated ice. The movable sheet can also be moved back and forth to dislodge the ice.
