Abstract: An automated tool that can handle a sheet. The tool may include a flexible membrane that is attached to a frame. The flexible membrane may include a vacuum opening that is adapted to pull the sheet into the membrane. The vacuum opening may pull the outer edges of the sheet out of a tray when the membrane is deflected to a flat position. The tool may then move away from the tray wherein the outer edges of the membrane and sheet are pulled from an adjacent sheet. This effectively “peels” the sheet out of the tray.

Abstract: A low dielectric constant material has a polymeric network that is fabricated from a first and a second component. The first component comprises a polymeric strand, and the second component comprises a molecule having a central portion with at least three arms extending from the central portion, wherein each of the arms includes a backbone with a reactive group. The first component and the second component form the polymeric network in a reaction that involves at least one of the reactive groups when the first and second components are thermally activated. Contemplated low dielectric constant materials are advantageously employed in the fabrication of electronic devices, and particularly contemplated devices include integrated circuits.

Abstract: A piece of baggage comprises a relatively small electronic sound recorder and playback device, and a designated location for the device that constrains the device in a relatively fixed position. The baggage is preferably a general purpose piece, and more preferably has at least one or two shoulder straps. Exemplary pieces of baggage are knapsacks and pocketbooks, although computer carrying cases and some strap containing briefcases may also fit within these limitations. The electronic sound recorder and playback device may contain any suitable electronic circuitry, and may advantageously be configured to provide or at least assist in providing an alarm. The device may also be configured to record speech, music, or other sounds. The recorder/playback device should have sufficient capacity to record at least 120 seconds of speech, although both greater or lesser capacities are also contemplated.

Abstract: An absorbing ether-like compound including a siliconethoxy, silicondiethoxy, or silicontriethoxy species attached to a naphthalene or anthracene chromophore via an oxygen linkage is used as an organic light-absorbing compound. The absorbing ether-like compound is incorporated into spin-on glass materials to provide anti-reflective coating materials for deep ultraviolet photolithography. A method of synthesizing the light-absorbing ether compounds is based on the reaction of an alcohol-substituted chromophore with an acetoxysilicon compound in the presence of alcohol. A method of making absorbing spin-on-glass materials including the absorbing ether-like compounds is also provided.

Abstract: Anti-reflective coating materials for deep ultraviolet photolithography include one or more organic dyes incorporated into spin-on-glass materials. Suitable dyes are strongly absorbing over wavelength ranges around wavelengths such as 248 nm and 193 nm that may be used in photolithography. A method of making dyed spin-on-glass materials includes combining one or more organic dyes with alkoxysilane reactants during synthesis of the spin-on-glass materials.

Abstract: A method of making a dielectric film on a substrate from a composition containing an organohydridosiloxane resin is presented. The organohydridosiloxane resins have a cage conformation and 40 mole percent or greater of an organic substituent. The process of making a dielectric film includes forming a solution of a solvent and the organohydridosiloxane resin, dispensing the solution on a substrate, spinning the substrate, baking the substrate to remove the solvent, and curing the substrate to form the dielectric film. The dielectric films of the present invention exhibit dielectric constants of approximately 2.8 or lower.

Abstract: A method of making a dielectric film on a substrate from a composition containing an organohydridosiloxane resin is presented. The organohydridosiloxane resins have a cage conformation and up to 40 mole percent of an organic substituent. The process of making a dielectric film includes forming a solution of a solvent and the organohydridosiloxane resin, dispensing the solution on a substrate, spinning the substrate, baking the substrate to remove the solvent, and curing the substrate to form the dielectric film.

Abstract: An organohydridosiloxane polymer having a cage conformation, between approximately 0.1 to 40 mole percent carbon-containing substituent, and a dielectric constant of less than about 3.0 is disclosed. Each silicon atom of the cage polymer is bonded to at least three oxygen atoms and to either a hydrogen atom or an organic substituent. By providing such a caged structure having essentially no hydroxyl or alkoxy substituents, either on the polymer backbone or at terminal silicon atoms, essentially no chain lengthening polymerization can occur in solution. Such organohydridosiloxane resins having a molecular weight in the range from about 400 to about 200,000 atomic mass units were formed using a dual phase solvent system and either a solid phase or a phase transfer catalyst to assist the condensation of hydridotrihalosilane with at least one organotrihalosilane.

Abstract: An apparatus for producing signs has a weeder portion for separation of an image element from a non-image element in a sign material to produce a weeded sign material, and a work surface that is mechanically coupled to the weeder portion to receive the weeded sign material. The work surface is sized and dimensioned to allow manual access to the weeded sign material, and the apparatus has a laminator portion mechanically coupled to the work surface to produce a laminated weeded sign material. In a method to produce a sign, a sign material is weeded in a weeder portion of a sign producing apparatus to produce a weeded sign material. The weeded sign material is transferred to a work surface where it can be further processed. The work surface is mechanically coupled to the weeder portion, and processed weeded sign material is laminated in a laminator portion of a sign producing apparatus.

Abstract: The loudspeaker comprises a cone (2) and a beading (4) attached to the cone (2). The beading (4) is composed of a sprayable plastic layer which is soft in its solid state. The manufacture of the loudspeaker is facilitated by a process in which an open negative mold (16) is used in which the cone (2) is arranged and immobilized. Following this, the plastic is sprayed into the open negative mold (16) and the beading (4) is formed as a soft plastic layer which attaches itself to the cone (2).

In particular, the radial beams comprise a flange that supports the redistribution tray and a web of the beams preferably includes a plurality of openings to allow the passage of fluids across the vessel. In addition, the webs also carry the channels. The radial beams also support the mixing chamber and, in the area between the wall of the mixing chamber and the vessel wall, the radial beams may have a vertical height that slopes downward from the vessel wall to the mixing chamber wall.
