A novel method is disclosed for fabricating weaving heddles from wire stock by passing the wire through a rolling mill to give the stock a substantially elongated, that is, a comparatively thin and wide cross section. Then a plurality of longitudinal notches are embossed in the stock spaced apart a distance generally equal to the desired length of the heddles, whereupon each notch is spread by means of a wedging tool into an elongated slot to form an eye and there is inserted an eyelet member th...

Methods, apparatus, and computer program, for use in fabricating a chemical array. The method may use an apparatus which includes a head system, a transport system, and a processor. The head system has multiple groups of drop dispensers which move in unison, each group having multiple dispensers. The transport system can move the head system with respect to a substrate with different dispensers of the groups following respective paths. The processor can dispense droplets from dispensers during o...

A light guide is produced by the out-diffusion of boron oxide through a free surface of a uniform borosilicate mass. The resulting structure consists of increased index silica rich regions near the surface in contact with lower index regions of a composition approaching that of the unmodified borosilicate. The out-diffusion process, generally carried out at a temperature approaching the softening point of the glass, may be applied to a borosilicate tube to result in a fiber preform. Fibers drawn...

Transmission mode negative electron affinity gallium arsenide (GaAs) photthodes and dynodes and techniques for the fabrication thereof, utilizing multilayers of GaAs and gallium alluminum arsenide (GaAlAs) wherein the GaAs layer serves as the emitting layer and the GaAlAs serves as an intermediate construction layer and/or as an integral part of the component.

With a method for the fabrication of multilayers a laminate is obtained by the stacking of layers, which are formed by a carrier provided with a conductor pattern and interleaved by adhesive layers. The laminate is subjected to a process which is carried out in at least three phases: in the first phase moisture and air are extracted from the space in which the laminate is placed, in the second phase the laminate is pressed together under increasing temperature and in the third phase the pressing...

An improved IR detector and method of fabrication is disclosed. The improved IR detector comprises at least one detector element having a slab of bulk intrinsic semiconductor material, a pair of spaced electrodes formed on said slab, the space between the electrodes forming an interelectrode dimension of the slab, and an active region selectively formed in the interelectrode dimension of the slab between the electrodes.

A diamond body and an oxide substrate are simultaneously sputter-etched such that the diamond body is cleaned and a layer of the sputtered oxide is deposited on the clean surface of the diamond body, then a metallic layer is deposited on the oxide layer. This provides a metallized diamond body whose metallic layer will adhere to the body.

A photon sensitive film resistor is provided having a resistance measured megohms per centimeter. The method of fabrication insures that the resistance is uniformly distributed along the current path.

A vent structure for reliable long term operation at high temperatures is fabricated by annealing a tubing of predetermined length and size, placing a predetermined number of strands of stabilized zirconium oxide yarn of predetermined diameter longitudinally into one end of the tubing a predetermined distance therein, flattening and coiling and pressing the end portion of the tubing containing the yarn at predetermined pressures, annealing the formed tubing, and installing a particulate filter i...

A technique for the fabrication of thin film electrets designed for use in electroacoustic transducers involves depositing a thin film of aluminum or titanium upon a perfluorinated foil and etching away the film prior to deposition of gold. The resultant structure evidences superior adhesion characteristics and electrical characteristics comparable to those previously described.
