Granted: 2005-06-21
Abstract: A method for fabricating high-resolution, biocompatible electrodes (11) is disclosed, allowing production of an electrochemical sensor which is capable of precise analyte concentration determination on a very small sample size. Electrically conducting material (3) is affixed to a first insulating substrate (4). A second insulating substrate (5) is then affixed to the electrically conducting material (3) and patterned using photolithography to define an electrode area (8). Alternatively, the electrically conducting material (3) may be screen printed directly onto a standard printed circuit board substrate (4) in the case of a counter or reference electrode. In either case, the substrate may be rigid or flexible. When the electrodes produced in accordance with the present invention are then used in an electrochemical sensor which includes a reagent, the small and highly-defined electrode areas (8,9) permit highly-accurate electrochemical  analyte measurements to be performed on very small sample sizes.

Filed: 1997-05-27
Granted: 2006-08-01
Abstract: An improved tensioner for an armature winder is provided which significantly reduces instantaneous increases in wire tension during winding or lead connection. System controls which control the drag of a hysteresis brake, monitor wire tension via a load cell, and control a dancer arm's position through limit sensors and a closed-loop proportional valve (which regulates the pressure within an air cylinder coupled to the dancer arm) are provided. These system controls significantly reduce instantaneous increases in wire tension during winding, during the start of winding, and during lead connection. A wire breakage detection device is also provided which monitors the wire during winding and signals the system controls if wire breakage is detected. Upon such detection, a rapid discharge valve discharges the air cylinder, and flyer arm rotation is halted prior to the wire becoming unthreaded from the flyer arm.

Title: Table-type electronic percussion instrument
Inventor: MIZUGUCHI MASAAKI
IPC: A47B37/00
Filed: 1997-07-15
Granted: 2001-11-06
Abstract: A table-type electronic percussion instrument is constructed of a table top, legs, pads as well as a musical-tone-generation circuit and a speaker system. Herein, the table board has a specific shape such as a pentagon-like shape which enables a number of persons to sit at it. The table top is supported by the legs and is constructed of a base material having a high rigidity and a finishing board like plywood. The finishing board covers a surface of the base material through which holes are formed. The pads are arranged on a surface of the dressing board to coincide with the locations of the holes. Sensors are provided inside of the holes and are attached to the backside of the finishing board. Thus, the sensors are arranged to detect a striking force imparted to any of the pads by a person. The musical tone generation circuit is provided beneath the table board to convert electric signals from the sensors to musical-tone signals. The speaker system is located beneath the table board to generate musical tones (e.g., percussion sounds) based on the musical-tone signals. For example, if the pads are to be reproduce electronic drums and/or electronic cymbals, the speaker system generates drum sounds and/or cymbal sounds when the pads are struck. Thanks to the table-like construction, the electronic percussion instrument can be shared by a number of persons to play an ensemble. Incidentally, the musical-tone-generation circuit contains a mixing circuit which performs mixing operations on the musical-tone signals corresponding to the pads and other musical tone signals supplied thereto. Thus, the musical-tone-generation circuit outputs mixed musical-tone signals, based on which the speaker system generates mixed musical sounds.

Abstract: L'invention concerne un procédé pour déceler, identifier et/ou trier des classes ou des sous-populations de molécules, en utilisant des marqueurs oligonucléotidiques. Les marqueurs oligonucléotidiques de l'invention comprennent des oligonucléotides choisis dans un jeu à hybridation croisée minimale. De préférence, ces oligonucléotides consistent chacun en une pluralité de sous-unités ayant de 3 à 9 nucléotides de longueur. Une sous-unité d'un jeu à hybridation croisée minimale forme un duplex ou un triplex présentant deux défauts d'appariement ou davantage avec le complément d'une autre sous-unité quelconque du même jeu. Le nombre de marqueurs oligonucléotidiques disponibles dans une forme d'exécution particulière dépend du nombre de sous-unités par marqueur et de la longueur de la sous-unité. Un aspect important de l'invention est l'utilisation de ces marqueurs oligonucléotidiques pour trier des polynucléotides par hybridation spécifique des marqueurs fixés aux polynucléotides, avec leurs compléments, sur des supports solides. Cette forme d'exécution permet d'assurer d'une manière automatique la manipulation et le triage de polynucléotides, ce qui est particulièrement utile dans des opérations parallèles à grande Bchelle, comme par exemple le séquençage d'ADN à grande échelle, la cartographie d'ARNm et dans des opérations similaires où de nombreux polynucléotides cibles ou de nombreux segments d'un polynucléotide cible unique sont séquencés simultanément.

Granted: 2002-04-23
Abstract: A robotic welding method for making a heat exchanger having tubes and inlet and outlet headers is disclosed. The headers have planar tubesheets and covers. The planar tubesheets are welded to the inlet and outlet ends of tubes. The tubesheets have two co-linear edge portions and a third edge intersecting a line through the two co-linear edge portions. The tubesheet has interior edges defining holes through which the ends of tubes extend. A robotic welding system is provided, with a sensor, a welding apparatus and a controller for controlling the movement and operation of the welding apparatus. The tubesheet is scanned to find the first and second co-linear edge portions, the third intersecting edge portion, and the face of the tubesheet. An actual origin is defined at the intersection of a first line through the first two co-linear edge portions found through scanning and a second line perpendicular to the line through the co-linear edge portions and extending through the third intersecting edge portion found through scanning and lying on the plane of the tubesheet face. The welding apparatus is moved to weld the tubesheet and tubes together. The positions of the welds are based upon the location of the actual origin of the tubesheet relative to the robotic system. After the tubesheet has been welded to the tube ends, the cover is welded to the tubesheet. The robotic welding system uses the same coordinate system that it has defined and performs additional scans of the cover to determine two points on each of the side faces of the cover and one point and each of the cover's end faces. The welding apparatus then welds the cover to the tubesheet along the edges of the cover faces.
