Patent CA-2658091-A1 (CA)
Inventor: YANAGIHARA MASAAKI
IPC: D02G1/08
Filed: 2007-07-11
Abstract: An unstretched multifilament yarn made of a PET type aromatic polyester containing a polyoxyalkylene polyether and an organic ionic compound is stretched and simultaneously false-twisted under specific conditions. The false twisting is stably conducted at a high speed without causing section deformation or fluffing to thereby give a yarn of a fibrous structure having an excellent texture and unsusceptibility to fibrillation. Thus, a polyester false twist yarn having excellent long-term antistatic properties is produced. The unstretched yarn in combination with an unstretched polyester yarn comprising a poly(methyl methacrylate) polymer and/or polystyrene polymer is stretched and simultaneously false-twisted under specific conditions to thereby stably produce at a high speed a composite false twist yarn which is free from fluffing, has excellent bulkiness, gives a spun-yarn feeling, and has excellent long-term antistatic properties. This composite false-twisted yarn is useful especially in applications where static electricity is desired to be diminished, such as school uniforms, uniforms, and dust-proof clothing.

Abstract: A pleated filter is made from a monocomponent monolayer nonwoven web of continuous monocomponent meltspun partially crystalline and partially amorphous oriented fibers of the same polymeric composition that are bonded to form a coherent and handleable web having a Gurley Stiffness of at least 100 mg and which further may be softened while retaining orientation and fiber structure. Rows of pleats are formed in the nonwoven web, and the web is cut to a desired size and shape to provide a pleated filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at at least some points of fiber intersection and having an average initial submicron efficiency of at least 15 % at a 1.52 meters/sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers, adhesive or other reinforcement in the filter media layer.

Patent CA-2661230-A1 (CA)
Inventor: KOSLOW EVAN E
IPC: D04H1/4382
Filed: 2007-05-29
Abstract: A process for making nanofibers includes preparing a fluid suspension of fibers, shear refining the fibers to create fibrillated fibers, and subsequently closed channel refining or homogenizing the fibrillated fibers to detach nanofibers from the fibrillated fibers. The shear refining of the fibers in the fluid suspension generates fiber cores having attached nanofibers. The closed channel refining or homogenizing of the fibrillated fibers is initially at a first shear rate and, subsequently, at a second, higher shear rate, to detach nanofibers from fiber cores and to create additional nanofibers from the fiber cores. The fiber suspension may flow continuously from the shear refining to the closed channel refining or homogenizing, and include controlling the rate of flow of the fiber suspension from the shear refining to the closed channel refining or homogenizing.

Abstract: A photocatalyst dispersion liquid contains titanium oxide particles, tungsten oxide particles, a phosphoric acid (salt) and a dispersion medium, and a containing amount of the phosphoric acid (salt) is from 0.001 mol times to 0.2 mol times with respect to the titanium oxide particles. In this photocatalyst dispersion liquid, the aggregation of the particles is suppressed and thus solid-liquid separation is not easily generated. According to this process for producing a photocatalyst dispersion liquid, titanium oxide particles are dispersed in a dispersion medium containing a phosphoric acid (salt) dissolved therein to obtain a titanium oxide particle dispersion liquid, and then tungsten oxide particles are mixed in the titanium oxide particle dispersion liquid.

Title: Method and apparatus for feedback signal generation in sigma-delta analog-to-digital converters
Inventor: SUNDSTROM LARS
IPC: H03M3/02
Filed: 2007-12-14
Abstract: A method and apparatus taught herein provide a digital-to-analog converter (DAC) for use in a conversion feedback path of a sigma-delta type analog-to-digital converter (ADC). The DAC uses current pulse shaping to generate a conversion feedback signal in each feedback cycle of the ADC that provides a consistent charge transfer for accurate digital conversion and has a controlled current pulse shape. In one or more embodiments, the DAC includes a capacitor circuit for charge storage and transfer and a (series) resistive circuit having variable resistance for current pulse shape control. In at least one embodiment, current pulse control limits a peak current of the conversion feedback signal, thereby reducing DC power consumption and gain-bandwidth (GBW) and slew rate requirements of the ADC's integration amplifier, and limiting residual (ending) current in each feedback cycle, which yields commensurate gains in (feedback cycle) clock jitter insensitivity.

Title: A lamp ballast and an illumination apparatus
Inventor: GORIKI TAKESHI
IPC: H02M7/48
Filed: 2008-04-16
Abstract: A illumination lamp ignition device is provided for making it possible to ignite a discharge lamp or an incandescent lamp on the optimum condition in all the cases. The ignition device is comprised of a DC-DC converter, an inverter that inverts the output from the DC-DC converter to an AC power and applies it to an illuminating load, an ignition circuit that generates a high voltage pulse from the AC power and outputs it to the illuminating load, and a controller that controls the DC-DC converter and the inverter to output a variable DC voltage and a variable frequency AC power. The controller has a starting mode that drives the inverter with a starting frequency to generate a high voltage pulse and an ignition mode for driving the inverter with an ignition frequency that is lower than the starting frequency. The controller also has a detection mode that makes the DC-DC converter output a predetermined level detecting DC voltage prior to an operation of the starting mode, a discharge lamp ignition program that makes the inverter operate the ignition mode subsequent to the starting mode after the detection mode, and an incandescent lamp ignition program that makes the inverter shift to the ignition mode without the involvement of the starting mode after the detection mode. When the detecting DC voltage is over a predetermined threshold value, the controller chooses the discharge lamp ignition program, but otherwise it chooses the incandescent lamp ignition program. At the time for the connection of the incandescent lamp, it can be ignited without applying the high voltage pulse, thereby preventing the reduction of its life.
